A cell is the basic unit of life, and death is inevitable for any cell. However, cancer cells that deviate from the normal track can resist death and survive. Ferroptosis is recently discovered as a modulated cell death different from other known forms of cell death in morphology, biochemistry, and genetics. It is characterized by iron-dependent lipid peroxidation regulated by various metabolic pathways. The incidence and mortality of genitourinary system cancer have been increasing recently. Although clinical practice therapy techniques have improved, no plan with a positive prognosis has been identified. For the therapy of cancer, ferroptosis opens up new avenues. Many studies have shown a complex link between ferroptosis and cancer, while some studies have also found the role of ferroptosis in genitourinary system-related cancers and therapeutic prospects. This article reviews the ferroptosis research progress in genitourinary system cancers, including bladder cancer, prostate cancer, ovarian cancer, and cervical cancer. It will also provide new ideas for the treatment of these cancers.

1  Introduction

Ferroptosis was originally discovered by Dixon et al. [1] in 2012 as a unique iron-dependent death, which is different from apoptosis, necrosis, and autophagy on a morphological, genetic and biochemical basis. It is due to lipid peroxide accumulation because of intracellular redox homeostasis imbalance caused by excessive iron. Iron chelating agents can reduce the iron level in cells and prevent the formation of active free radicals, preventing cell death [1]. Iron is a redox-active metal involved in the free radical formation and lipid peroxidation that plays an important role in controlling cell death. The sensitivity of cells to ferroptosis is regulated by various genes or proteins involved in iron homeostasis [2]. Cancer cells usually rely on more iron to fuel their growth than normal non-cancer cells, making them more susceptible to ferroptosis. Glutathione peroxidase4 (GPX4) is a selenoprotein expressed in most tissues and organs. It can detoxicate complex phospholipid hydroperoxide and inhibit the production of reactive oxygen species (ROS). GPX4 has been identified as a central regulator of ferroptosis, and inhibition of GPX4 activity or knockdown of the GPX4 gene can induce ferroptosis [3]. GPX4 typically reduces toxic phospholipid hydroperoxides into lipid alcohols using two electrons provided by glutathione (GSH). GSH is a tripeptide antioxidant synthesized from cysteine and is also the cofactor of many enzymes. Almost all cells can synthesize this thiol tripeptide and protect against the harmful effects of various endogenous stresses. Erastin can indirectly inactivate GPX4 by lowering GSH levels, leading to ROS accumulation and lipid peroxidation [1,4]. System Xc  and sulfur transfer pathways are the main sources of cysteine. Altering the GPX4 function through GSH depletion and cysteine starvation can lead to ferroptosis [1]. The system Xc consists of both the heavy chain SL7A11 (xCT) and a light chain SLC3A2 (4F2hc) that is connected by a disulfide bond; it absorbs extracellular cysteine and discharges intracellular glutamate, which is very important for the exchange of the system [5] (Fig. 1). However, due to the sulfur transfer pathway, some cells are resistant to ferroptosis and induced by inhibiting the system Xc function (such as Erastin).


Figure 1: Mechanisms of ferroptosis. Erastin, sorafenib, sulfasalazine, etc., promote ferroptosis by inhibiting system Xc ; RSL3, Withaferin, et promote ferroptosis by inhibiting GPX4; Intracellular iron ions generate ROS through fenton reaction; TfR and FPN regulate intracellular iron uptake and excretion, respectively

Ferroptosis-inducing agents (FINs) can be roughly divided into four main categories based on their modes of action: increasing intracellular labile iron pool (LIP); depleting GSH; depleting GPX4 and CoQ10 by the SQS-mevalonic acid pathway and targeted inactivation of GPX4 [6]. Recently, some new signaling pathways and regulatory factors have also been found to play a role in ferroptosis. A common example is the acyl CoA synthetase long-chain family member 4 (ACSL4) gene, which can regulate ferroptosis [7,8], Cell contact through the NF2-Hipo-Yap axis can resist ferroptosis caused by the cysteine starvation and GPX4 inactivation [9], and heat shock protein beta-1 (HSPB1) is a negative regulator of ferroptosis [10]. Interestingly, ferroptosis has been found to play an important role in cancer, acute renal failure, neurodegenerative diseases, diabetes, and other diseases. The emergence of ferroptosis has profoundly impacted various areas of life science, and a comprehensive understanding of the mechanism of ferroptosis will also help us solve existing diseases, especially cancer.

2  Ferroptosis and Genitourinary System Cancer

2.1 Ferroptosis and Cancer

As the second leading cause of death worldwide, cancer threatens human health. Current cancer treatment methods are not very successful in eradicating cancer. However, many anticancer drugs have been used for clinical treatment and have also shown good therapeutic effects. However, serious problems exist, such as apoptosis avoidance, drug side effects, and drug resistance. The characteristics of iron addiction and ROS tolerance of cancer cells make them sensitive to ferroptosis. Recent evidence has shown that ferroptosis is related to cancer’s occurrence, progression, and drug resistance [11]. For example, metallothionein-1G knockout enhances the sensitivity of hepatocellular carcinoma to Sorafenib by promoting ferroptosis [12]. Furthermore, cancer of the genitourinary system has always been a serious threat to human life for both genders. Here, in this study, we will review the latest research advancement and progress of ferroptosis in the prostate, bladder, ovarian and cervical cancer, providing new approaches for treating related diseases.

2.2 Ferroptosis and Prostate Cancer

Prostate cancer (PCa) is the most common malignant tumor worldwide and is one of the three most common cancers in the United States [13]. About 10% of men who receive PCa treatment have metastasis [14]. Current metastatic disease treatment depends on androgen deprivation and androgen receptor (AR) regulation. However, androgen-targeted therapy usually fails in most patients with PCa and develops into castration-resistant prostate cancer (CRPC). Identifying more accurate markers is essential to improve the diagnosis and treatment of PCa [15] (Fig. 2). Based on the discovery of ferroptosis, Liao et al. [16] found that Pannexin 2 gene can be used as a new marker of ferroptosis and the malignant phenotype of prostate cancer cells. Pannexin 2 is necessary for the metastasis and invasion of the PCa cells. The expression of Pannexin 2 was significantly upregulated in the PCa tissues and cell lines as well, and it is considered to be an important factor affecting the severity of PCa. Therefore, Pannexin 2 can be used as a specific marker in patients with PCa. Knockdown of the Pannexin 2 results in increased intracellular iron divalent level and accumulation of malonaldehyde (MDA) which is a representative end-product of lipid peroxidation. The Nrf2 pathway plays a key role in ferroptosis. It was found that Pannexin 2 knockout can significantly reduce the mRNA and protein expression of Nrf2, as well as the expression of downstream genes (HO-1 and FTH1). Blocking the expression of Pannexin 2 can inhibit the proliferation, migration, and invasion of the PCa cells and increase the levels of ferrous iron and MDA. The Nrf2 activator oltipraz can restore the damage caused by Pannexin 2 knockout [16].


Figure 2: Ferroptosis and prostate cancer. Knockout of pannexin 2 and DECR1 induces ferroptosis; pannexin 2 knockout results in increased iron divalent ion and MDA levels, as well as decreased Nrf2 expression, thereby inhibiting HO-1 and FTH1 expression; Oltipraz can rescue the effect caused by pannexin 2 knockout; ITC-Ari-BSO not only acts on AR but also down-regulates GSH and promotes ferroptosis

Studies show that Pannexin 2 regulates the malignant phenotypes and ferroptosis of PCa cells via the Nrf2 pathway, and this target could be used as a novel treatment for PCa. If this approach is validated in vivo, Pannexin 2 could be used as the biomarker for early detection of PCa and a new method for treating PCa, which will ultimately benefit treating the disease. Nassar et al. [17] found that the DECR1 gene is upregulated in clinical prostate tumors, and DECR1 expression is closely related to the progression of PCa and the patient’s prognosis. By knocking out DECR1, lipid peroxidation and ferroptosis can be induced, and PCa proliferation and metastasis can be inhibited. For the treatment of CRPC, Qin et al. [18] designed and synthesized isothiocyanate (ITC) mixed AR antagonists (ITC-ARi). A reasonable combination of ITC-ARi and Buthionine sulfoximine (BSO), an inhibitor of GSH synthesis, could effectively down-regulate AR/AR splicing variants and induce ferroptosis in CRPC cells. This combination approach provides new ideas for the treatment of CRPC. Some studies have shown that the key factors regulating ferroptosis (GPX4, TFRC, FPN, Iron) may also play an important role in prostate cancer. Studies about androgen targeting therapy in prostate cancer have shown that GPX4 dependence and ferroptosis hypersensitivity in persister cells are associated with extensive lipid remodeling [19]. Overexpression of the transferrin receptor (TFRC) promotes the proliferation, migration, and invasion of the PCa cell lines [20]. Recombinant Ferroportin (FPN) inhibits the proliferation of prostate cancer cells by influencing both the iron efflux and cell cycle regulators [21]. At different stages of PCa (androgen-sensitive and insensitive), increasing iron content in the treatment strategies maximizes efficacy and may overcome resistance to the existing therapies [22]. It is important to note that Zhao et al. examined the cell survival of androgen-sensitive PCa cell line LNCaP and CRPC-like PCa cell line LNCAP-AL after treatment with the GPX4 inhibitor RSL3. They discovered that the former was more resistant to ferroptosis. And the activation of PLA2G4A by ATF6 controls this resistance. Based on this, they found that enzalutamide and the ATF6 inhibitor Ceapin-A7 can work together to halt the course of CRPC and trigger ferroptosis (2022) [23]. According to reports, apoptosis resistance is the fundamental mechanism of therapeutic resistance in PCa. Samy et al. discovered that diallyl trisulfide (DATS) could trigger ferroptosis targeting PCa and override apoptosis resistance [24]. Ferroptosis may be used to overcome the cancer cells’ resistance to apoptosis. Although studies on the regulation of ferroptosis in prostate cancer are frequently reported and showed a good therapeutic prospect, the real application of ferroptosis in clinical treatment needs both in vivo experiment validation and multi-demonstration.

Surprisingly, ferroptosis can predict disease-free survival (DFS) and immunotherapy response for PCa patients following radical prostatectomy in addition to killing cancer cells [25,26]. In addition, by comparing the data of whole genome patients, Li et al. [27], they were found that the characteristics of genomic changes in Chinese patients were significantly different from those in western populations, and the mutations or deletions of these genes may have other effects on the occurrence of ferroptosis. Therefore, accelerated research on the role of ferroptosis in prostate cancer will provide new strategies for treating prostate cancer patients and, hopefully, the radical treatment of prostate cancer.

2.3 Ferroptosis and Bladder Cancer

Bladder cancer (BCa) is one of the most common epithelial malignancies and the second most common urogenital malignancy globally [28]. In China, bladder cancer ranks first among male genitourinary malignancies. Depending on the extent of the tumor invasion and depth, BCa can be classified as either muscle-invasive bladder cancer (MIBC) or non-muscle-invasive bladder cancer (NMIBC). Radiation therapy, adjuvant immunotherapy, radical cystectomy (RC), and other options are available to patients with the former [29]. Intravesical chemotherapy and intravesical bacillus Calmette-Guérin (BCG) immunotherapy are two treatment options for NMIBC patients [30]. One of the primary treatments for BCa is cisplatin-based combination chemotherapy, but the effectiveness of this treatment has been severely limited due to the development of cisplatin resistance. In 2014, Drayton et al. [31] discovered a new mechanism of cisplatin resistance: Increased microRNA-27a expression mediates the intracellular glutathione regulation. Cisplatin resistance is mediated by the increased SLC7A11 expression and glutathione production. Overexpression of miRNA-27a reduces SLC7A11 and intracellular glutathione levels and re-sensitizes drug-resistant cells to cisplatin. Inhibition of SLC7A11 by sulfasalazine also re-sensitized the cisplatin-resistant bladder cancer cells. Both glutathione and SLC7A11 are also considered regulatory factors in ferroptosis. Although Drayton RM did not directly associate this result with the ferroptosis, FINs could inhibit SLC7A11 function and reduce the GSH production. Thus, we speculated that FINs might also play a similar role in cisplatin resistance in bladder cancer. However, this needs further experimental proof, and this method may be a new way to treat bladder cancer. Currently, there is no direct report on how ferroptosis regulates bladder cancer, but current studies show that ferroptosis-related factors play an important role in bladder cancer. For example, reduced serum iron ion levels may be an important cause of bladder cancer [32]. The expression of MIR497HG inhibits the growth, migration, and invasion of BCa cells in vitro by affecting Hippo/YAP and TGF-β/Smad signaling pathways [33]. Verteporfin inhibits YAP-induced bladder cancer cell growth and invasion through the Hippo signaling pathway [34]. Genetic variation in the GSH pathway may affect cancer recurrence in non-muscle-invasive bladder cancer patients [35]. Inhibiting the expression of YAP and Nrf2 can affect the migrative ability of drug-resistant bladder cancer cells and significantly improves the sensitivity to cisplatin [36]. At the same time, an accurate cancer prognosis can improve the survival rate of patients. Zhou et al. developed a bladder cancer risk model based on ferroptosis, which can help clinicians evaluate the prognosis, immunotherapy outcome, and chemotherapy response of patients with bladder cancer [37]. Xia et al. developed a scoring system based on ferroptosis to predict the prognosis of BCa patients and is closely connected to TNM classification, tumor grade, and other clinical characteristics [38]. There are numerous reports about the prediction of BCa at this time [3942]. Treatment of bladder cancer benefits from knowledge of the connection between ferroptosis and bladder cancer. In addition to paying close attention to the prognosis of ferroptosis on BCa, we should also investigate the molecular mechanism of ferroptosis in the therapy of BCa.

2.4 Ferroptosis and Ovarian Cancer

Ovarian cancer is one of the most common cancers in women and is a highly fatal gynaecological malignant tumor worldwide [43]. Clinically, ovarian cancer exhibits a deceptive beginning. Most ovarian cancer patients pass away from advanced disease because there are few reliable symptoms and biomarkers at an early stage. One of the current conventional therapies for advanced ovarian cancer is platinum-based chemotherapy. Since ferroptosis was reported, many studies have shown a strong link between iron death and ovarian cancer (Fig. 3). In 2017, Basuli et al. [44] found iron “addiction” is a new target in ovarian cancer treatment. The increase of iron efflux can inhibit the proliferation of ovarian cancer cells and reduce the tumor load and metastasis of ovarian cancer in vivo. They noted that ovarian cancer stem cells are sensitive to both the ferroptosis-inducing drugs and iron-chelating agents, providing a new target for ovarian cancer treatment. Cisplatin is the most effective anticancer drug, but it has significant limitations due to drug resistance of tumor cells and toxic side effects caused by high drug use. Chan et al. [45] found that MAP30 isolated from the bitter gourd seeds can also act as a FIN for ovarian cancer cells. MAP30 can enhance lipid peroxidation by inhibiting the GPX4, reducing GSH/GSSG ratio, and increasing ROS quantity. In addition, MAP30 can inhibit the migration, invasion, and proliferation of cancer cells in various ovarian cancer cells without producing adverse reactions. It can also enhance the sensitivity of cancer cells to cisplatin when combined with cisplatin. Meanwhile, Cheng et al. [46] showed that Erastin, in conjunction with cisplatin, inhibits ovarian cancer growth via ferroptosis in vivo and in vitro. In particular, HE staining of tissue sections showed a low degree of organ injury upon cisplatin and Erastin combination therapy. The combination therapy induces the increased ACSL4 and COX-2 expression in HEY cells and significantly inhibits the GPX4 and FTH1 expression. Although this is an effective therapeutic approach, Erastin cannot be used directly in the clinic as it is metabolically unstable in vivo. Therefore, searching for Erastin analogues or alternative compounds will open new avenues for the clinical treatment of ovarian cancer worldwide. In 2019, Tesfay et al. [47] found that stearoyl-CoA-desaturase-1 (SCD1) is highly expressed in ovarian cancer; blocking SCD1 in vitro and in vivo can regulate lipid metabolism and make ovarian cancer cells sensitive to the FINs. In addition, researchers found that SLC7A11 is a key ferroptosis factor that significantly upregulated ovarian cancer cells. Sun et al. [48] reported that cocaine extract lidocaine promotes ferroptosis in ovarian cancer cells via targeting the miR-382-5p/SLC7A11 axis. Lidocaine upregulates miR-382-5p and subsequently inhibits the SLC7A11 to induce ferroptosis. However, due to the lack of direct evidence and model validation of the effect of lidocaine on ferroptosis, its clinical value in the treatment of ovarian cancer needs to be demonstrated in detail. Drug inhibition of Poly ADP-Ribose polymerases (PARP) is the main treatment strategy for breast cancer (BRCA) mutant ovarian cancer. Hong et al. [49] found that PARP inhibition promotes ferroptosis by inhibiting the SLC7A11. They demonstrated that the PARP, in combination with FINs, can sensitize BRCA-proficient ovarian cancer cells to PARP inhibitor olaparib, which provides a promising treatment strategy for using PARP inhibitors in BRCA-proficient ovarian cancer. Jin et al. discovered that SNAI2 knockdown would reduce the production of SLC7A11 protein and enhance the occurrence of ferroptosis, which can decrease the advancement of ovarian cancer. SNAI2 is a zinc finger protein that encodes the SNAI transcription factor family. The authors discovered that SNAI2 could bind to the GPX4 promoter as well as the SLC7A11 promoter at the same time. However, they did not specify specifically how these two promoters were related [50]. Inhibiting the growth of ovarian cancer and promoting ferroptosis may be the dual targets of SNAI2. Cai colleagues. Discovered that the lncRNA ADAMTS9-AS1 attenuates ferroptosis in epithelial ovarian cancer by inhibiting the miR-587/SLC7A11 axis [51]. These data suggest that SLC7A11 may significantly influence the relationship between ferroptosis and ovarian cancer. Cancer cells avoid ferroptosis through genetic regulation of the expression of related proteins. Recently, You et al. [52] constructed an ovarian cancer scoring system based on ferroptosis-related gene expression and discovered a potential drug, DMOG, which can help doctors predict tumor progression. To maintain their ability to increase, ovarian cancer cells appear to have bidirectional resistance to ferroptosis and apoptosis. An important treatment approach is to influence the death mechanism of cancer cells in multiple directions. Further research into the connection between ferroptosis and ovarian cancer is extremely important.

2.5 Ferroptosis and Cervical Cancer

Currently, cervical cancer remains the leading cause of cancer-related death in women worldwide. Persistent infection with high-risk human papillomavirus (HR-HPV) is the primary cause of cervical cancer [53]. There are more than 200 types of HPV, but only 52 types can cause cancer development. According to clinical data and related studies, HPV types 16 and 18 are closely associated with the occurrence of cervical cancer. Although chemotherapy, radiotherapy, and surgery are available, the survival rate is quite low due to tumor recurrence, metastasis, and drug resistance. The discovery of ferroptosis provides a new target for the treatment of cervical cancer (Fig. 4). Wu et al. [54] found that the expression level of circEPSTI1 was high in cervical cancer cells, and the knockout of this gene could inhibit the proliferation of cervical cancer cells. By silencing circEPSTI1, it was found that the ratio of GSH/GSSG and the expression of GPX4 were decreased, and the accumulation of lipid peroxides on the cell membrane is increased in ferroptosis, which was caused by the inhibition of the SLC7A11 expression. This is the first time circRNAs are associated with ferroptosis, providing a new target for treating cervical cancer. Xiaofei et al. [55] also found that oleanolic acid (OA), a substance naturally existing in leaves, fruits, and roots of plants, inhibits the proliferation of cervical cancer cells by regulating the ACSL4 ferroptosis signaling pathway. ACSL4-mediated activation of ferroptosis reduces the size of cervical cancer tumors and the viability of Hela cells. At the same time, OA, as a natural activator of ACSL4, may enhance its anticancer effect in cervical cancer. This study suggests that OA may be a potential anticancer drug for cervical cancer. According to research on Sanguinarine (SNG) by Alakkal et al. [56], SNG caused ferroptosis through SL7A11 and apoptosis through caspase-3 in human cervical carcinoma. A second death mechanism was likewise blocked by the administration of an RCD inhibitor [56]. This raises the question of whether cancer cells’ regulation of H2O2 is what leads to medication resistance. To address the issue of treatment resistance, it is crucial to study how cancer cells control H2O2. Ferroptosis, however, does not always have an anti-tumor impact. According to Wang et al. [57], an anti-ferroptosis impact would be triggered by prolonged ferroptosis. This effect raises the Kirsten rat sarcoma viral oncogene homolog (KRAS), which accelerates the development of squamous cell carcinoma (SCC) [57]. Additionally, Liu et al. discovered that miR-193a-5p/GPX4 and circular RNA circACAP2 prevented ferroptosis in cervical cancer’s malignant progression [58]. An important development in the fight against tumor treatment resistance is discovering the relationship between ferroptosis and apoptosis. The impact of genes associated with ferroptosis in determining the prognosis of cervical cancer has also been found in related investigations [59,60]. The use of ferroptosis in diagnosing and treating.

3  Prospect

Cell death plays an important role in normal development, homeostasis, and prevention of hyperproliferative diseases. With the discovery of ferroptosis’s role in the treatment of human diseases, the ferroptosis mechanism has attracted more and more attention from researchers, and new FINs have gradually entered people’s vision, such as iron-based nanomaterials based on nanotechnology (iron oxide nanoparticles, FePt nanoparticles, etc.) and indirect iron-based nanomaterials. Iron oxide nanoparticles have been found to kill cancer cells by increasing iron and ROS levels. Cancer is scary because it has many biological characteristics, such as autonomy, aggressiveness, metastasis, abnormal differentiation, loss of contact inhibition, etc. Since cancer cells are sensitive to iron, inducing ferroptosis in the cancer cells by the ferroptosis mechanism will be a new way of cancer treatment. In addition, transfection key factors such as P53 and ACSL4 into tumor cells can also be used for cancer treatment. Ferroptosis opens a new avenue for treating malignant tumors of genitourinary system cancer, including prostate, bladder, ovarian and cervical cancers, which seriously threaten mental and physical health. Combining ferroptosis with traditional cancer treatments to trigger multimodal cancer cell death or finding new cancer therapies based on ferroptosis is expected to make a breakthrough in the current clinical cancer treatment.
