Abstract Background: HLA-DMA presents pathogen-derived antigens to CD4+ and CD8+ T cells, respectively, and plays a significant part in initiating the immune response. So far, the impact of HLA expression on the prognosis of BC cells is controversial, because few studies have shown that the expressions of some HLA genes are related to the improvement of the survival rate. Up till now, however, the relationship between HLA-DMA and LUAD has not yet been assessed. Methods: We analyzed the TCGA database and assessed the prognostic value of HLA-DMA in LUAD. We conducted the Kruskal–Wallis and Wilcoxon signed-rank test and utilized logistic regression… More >

Abstract 5-Fluorouracil (5-FU) is a commonly used chemotherapeutic agent for various cancers. However, the drug resistance developed by tumor cells hinders the therapeutic effect. Konjac glucomannan (KGM) is indicated to sensitize 5-FU-resistant hepatocellular carcinoma (HCC) cells to 5-FU. In our study, we found that KGM or 5-FU treatment alone did not affect the malignant cell behaviors and endoplasmic reticulum (ER) stress of 5-FU-resistant HCC cells or HepG2/5-FU and Bel-7402/5-FU cells, while cotreatment with KGM and 5-FU significantly facilitated HCC cell apoptosis and ER stress and suppressed cell proliferation potential and migration abilities. Moreover, we explored the underlying mechanism by which KGM… More >

Abstract PARP inhibitors have proven to be effective in conjunction with conventional therapeutics in the treatment of various solid as well as hematologic malignancies, particularly when the tumors are deficient in DNA repair pathways. However, as the case with other chemotherapeutic agents, their effectiveness is often compromised by the development of resistance. PARP inhibitors have consistently been reported to promote autophagy, a process that maintains cellular homeostasis and acts as an energy source by the degradation and reutilization of damaged subcellular organelles and proteins. Autophagy can exhibit different functional properties, the most prominent being cytoprotective. In addition, both cytotoxic and non-protective… More >

Abstract Glioma is a commonly diagnosed brain tumor that shows high mortality rate. Despite the great advancement of cancer therapy in recent years, chemotherapy is still an important approach for treatment of glioma. However, long-term chemotherapy usually causes serious side effects or complications. It is desirable to take strategies to enhance the efficacy of current chemotherapy. In the present study, we observed obvious upregulation of miR-374a in glioma cells. More importantly, we found that knockdown of miR-374a was able to enhance the etoposide-induced cytotoxicity against glioma cells. Mechanically, we demonstrated that FOXO1 was the target of miR-374a in glioma. Treatment with… More >

Abstract Apatinib is an oral TKI with antiangiogenic properties, and it is currently approved for the treatment of advanced gastric cancer in China. This agent has also been tested in other human solid tumors, including non-small cell lung cancer (NSCLC). Since the combination of chemotherapy and an antiangiogenic agent has been shown to be a feasible strategy in NSCLC, it is conceivable that a similar approach combining apatinib with chemotherapy may yield clinical activity. With this in mind, we investigated the efficiency of apatinib in combination with pemetrexed or docetaxel in advanced NSCLC. We treated a total of 20 patients with… More >

Abstract The main purpose of the study was to enhance the stability and therapeutic effects of Curcumin (Cur) through nanoformulation with gum Arabic (GA) as a coating agent through an efficient synthetic approach. The antioxidant properties of the developed nanoparticles (Cur/GANPs) were assessed through several in vitro assays, such as β-carotene bleaching activity, DPPH, and nitric oxide scavenging activities in addition to evaluating its inhibitory activity on angiotensin-converting enzyme (ACE). The cytotoxicity of Cur/GANPs was evaluated in vitro using different types of human cancer cells including breast cancer (MCF7, MDA-MB231), liver cancer (HepG2), and colon cancer (HT29) cells. The prepared particles… More >

Abstract

Microbial infections cause complicated health influences along with bad economic impacts. In the present investigation, three dominant seaweeds namely, Amphiroa anceps, Corallina officinalis and Sargassum filipendula were collected from different Egyptian sites at the Red Sea and Mediterranean Sea during autumn 2019. Organic extracts of the three algae were screened for their antibacterial activity against three pathogenic bacteria Salmonella typhiimurium, Staphylococcus aureus and Escherichia coli, in addition to in vitro antiviral activity against Rotavirus (RV), and Coxsackie virus B3 (CVB3) that cause severe diseases in human. Organic extract of A. anceps, C. officinalis and S. filipendula inhibit E. coli cells… More >

Abstract The medicinal plant of Acer tegmentosum Maxim is traditionally used in the southern part of Asia to treat oxidative stress-related diseases, including cancer, diabetes mellitus , wounds, infections, etc. Based on this, the current study was designed to investigate the phytochemical analysis, antioxidants and anti-cancer activities of Acer tegmentosum Maxim (AT). The total phenolic content (TPC), total flavonoid content (TFC), free radicals scavenging (DPPH and ABTS), chemical constituents as well as cytotoxicity potential ATWE (Acer tegmentosum Maxim water extracts) and ATEE (Acer tegmentosum Maxim ethanolic extracts) were tested. The cytotoxic efficacy ATWE and ATEE were studied in Human embryonic kidney… More >

Abstract This study aimed to identify the chemical composition of essential oil from fruits (EOAF) and the hexanic crude extract from aerial parts (At-Hex) of atemoya (Annona cherimola x Annona squamosa), a hybrid belonging to the Annonaceae family. Cytotoxic and antimicrobial activity was also evaluated. OEAF was obtained by hydrodistillation using a Clevenger apparatus, and their composition was analyzed by gas chromatography-mass spectrometry (GC-MS) analyses. Cytotoxicity was tested against human tumor cell lines HCT-116 (colon carcinoma), SF-295 (glioblastoma), OVCAR-8 (ovarian carcinoma) and HL60 (leukemia) using 3-(4,5-dimethyl-2-thiazolyl)-2,5- diphenyl-2H-tetrazolium bromide (MTT) assay, while antimicrobial activity was conducted by bioauthography method against eleven microorganisms… More >

Abstract A protective action of melatonin (MELAT) on docetaxel (DCT)-induced inflammation, apoptosis, and reactive free oxygen radical (fROS) generation values via blocking of TRPM2 calcium-permeable channel was investigated in different cells except for laryngo-tracheal epithelial (LT-Epi) cells. Hence, the protective action of MELAT on DCT-induced oxidative toxicity and inflammation in LT-Epi tissue and cells of mice were investigated in the current study. MELAT treatment ameliorated DCTinduced mitochondrial ROS in the LT-Epi cells by reducing the generation of fROS (cytosolic and mitochondrial), lipid peroxidation, and depolarization of the mitochondrial membrane, while increasing reduced glutathione (GSH), GSH peroxidase, and total antioxidant status.
