Abstract Background: Photodynamic therapy (PDT) may eradicate residual malignant cells following sarcoma resection, through reactive oxygen species (ROS) mediated cytotoxicity, thus improve clinical outcomes. This study aims to assess the efficacy of 5-aminolevulinic acid (5-ALA) as a photosensitizer in combination with red light (RL) for PDT of bone sarcoma cells in vitro. Methods: Three bone sarcoma cell lines underwent treatment with 5-ALA and RL or sham-RL (SL). 5-ALA uptake was assessed using flow cytometry. Production of ROS was measured using CellROX Green staining and fluorescence microscopy. Cell viability was assessed using Cell Counting Kit-8 assays. Results: All cell… More >

Abstract Colorectal cancer (CRC) is the third most common malignancy worldwide and the second leading cause of cancer-related deaths, accounting for approximately 10% of all cancer cases. By 2050, CRC incidence is expected to rise substantially, driven by population aging and greater exposure to risk factors in developing countries. Despite advances in medicine and pharmacy, the effectiveness of available treatments remains limited, underscoring the urgent need for innovative therapeutic strategies. This review summarizes and critically evaluates currently available CRC therapies and explores new emerging directions. Particular attention is given to the role of immunotherapy, targeted therapies,… More >

Abstract The prolonged and intricate history of oncological treatments has transitioned significantly since the introduction of chemotherapy. Substantial therapeutic benefits in cancer therapy have been achieved by the integration of conventional treatments with molecular biosciences and omics technologies. Human epidermal growth factor receptor, hormone receptors, and angiogenesis factors are among the established therapies in tumor reduction and managing side effects. Novel targeted therapies like KRAS G12C, Claudin-18 isoform 2 (CLDN18.2), Trophoblast cell-surface antigen 2 (TROP2), and epigenetic regulators emphasize their promise in advancing precision medicine. However, in many cases, the resistance mechanisms associated with these interventions… More >

Abstract Breast cancer is one of the most prevalent malignancies among women and comprises a heterogeneous spectrum of molecular subtypes with distinct biological behaviors. Among various regulatory molecules, sphingolipids play pivotal roles in dynamically modulating fundamental cellular processes such as proliferation, apoptosis, and metastasis through metabolic interconversions, including phosphorylation, glycosylation, and the generation of sphingosine-1-phosphate. This review aims to elucidate the mechanisms through which sphingolipid metabolism orchestrates cancer cell fate and drives breast cancer progression. Particular emphasis is placed on the balance between proapoptotic ceramides and pro-survival metabolites, such as sphingosine-1-phosphate, which collectively influence tumor growth More >

Abstract Uveal melanoma (UM) is the most common intraocular cancer, with approximately 5.2 individuals per million affected annually in the United States. It represents approximately 3% of the global malignant melanoma cases, accounting for 80% of the overall noncutaneous melanomas. Clinically, it remains silent in about 30% of the cases; when symptomatic, it generally causes metamorphopsia (painless loss or distortion of vision) and/or photopsia (flashing or flickering of light in the visual field). Discoloration of the iris, astigmatism, glaucoma, and even blindness are other, less common clinical manifestations. Several pathophysiological mechanisms underlie the development of UM.… More >

Abstract Parasitic infections are increasingly recognized as contributors to cancer development, yet the underlying oncogenic mechanisms remain insufficiently understood. Growing evidence from molecular oncology, immunology, and microbiome research suggests that chronic parasitic infections may drive tumorigenesis through sustained inflammation, deregulated signaling pathways, genomic instability, and the release of parasite-derived exosomes that reshape the tumor microenvironment. These insights underscore the need to integrate parasitology with cancer biology to understand infection-associated malignancies better. The aim of this narrative review is to synthesize current knowledge on how selected parasites contribute to cancer development and to highlight emerging therapeutic and… More >

Abstract Lung cancer is the most common but fatal malignant tumor worldwide. Patients with lung cancer experienced a relatively low 5-year overall survival rate, and issues such as metastasis and drug resistance remain prominent challenges in its clinical management. Neddylation, a novel type of post-translational modification, was overactivated in lung cancer and was closely associated with its occurrence, development, metastasis, and drug resistance.

Abstract Prostate cancer (PCa) remains a major cause of cancer-related mortality in men, largely due to therapy resistance and metastatic progression. Increasing evidence highlights the tumor microenvironment (TME), particularly cancer-associated fibroblasts (CAFs), as a critical determinant of disease behavior. CAFs constitute a heterogeneous population originating from fibroblasts, mesenchymal stem cells, endothelial cells, epithelial cells undergoing epithelial–mesenchymal transition (EMT), and adipose tissue. Through dynamic crosstalk with tumor, immune, endothelial, and adipocyte compartments, CAFs orchestrate oncogenic processes including tumor proliferation, invasion, immune evasion, extracellular matrix remodeling, angiogenesis, and metabolic reprogramming.

We previously found a strong correlation between SH3 domain GRB2-like endophilin B1 (SH3GLB1) and superoxide dismutase 2 (SOD2), which converts O₂ to hydrogen peroxide (H₂O₂). Prior studies show that H₂O₂ redox signaling is vital for physiological processes and can drive tumor progression. Therefore, we aim to define how H₂O₂ signaling regulates SH3GLB1 and AKT (protein kinase B) pathways in GBM and to assess whether modulating H₂O₂ reverses temozolomide (TMZ) resistance.

Abstract Background: In clinical practice, approximately 80% of prostate cancer (PC) cases are localized and can achieve favorable outcomes with appropriate treatment. Conversely, some remaining cases exhibit an aggressive phenotype or develop resistance to therapeutic interventions, leading to tumor metastasis and a poorer prognosis.
