Abstract Spermatogenesis is a complicated and highly regulated male gamete differentiation process that begins with the proliferation and differentiation of spermatogonia to the release of the mature spermatozoa. The autophagy-related gene atg7 has been reported as closely related to spermatogenesis and communication of Sertoli cell-germ cells in mice, including acrosome biogenesis, sperm flagellum development, and ectoplasmic specialization assembly. However, the function of es-ATG7 and its molecular regulatory mechanism during spermatogenesis in Crustacea remain largely unknown. Here, we cloned and identified es-atg7 from the testes of the Chinese mitten crabs Eriocheir sinensis and found that the expression of es-atg7 was relatively high… More >

Abstract Objective: This study aimed to explore the miR-1247-mediated promotion of osteosarcoma (OS) cell proliferation by SOX9. Methods: We recruited 97 OS patients admitted to our hospital (the observation group, OG) and 82 healthy people undergoing physical examinations (the control group, CG) over the same period into this study. The expression of miR-1247 and SOX9 in human OS cells in vitro was tested to determine the effect of miR-1247 and SOX9 on OS and to analyze the relationship between miR-1247 and SOX9. Results: We detected lowly expressed miR-1247 and highly expressed SOX9 in the peripheral blood of OS patients (P <… More >

Abstract Soybean agglutinin (SBA) is an important anti-nutritional factor in soybean. SBA can induce animal growth inhibition, cause pathological changes of intestinal tissue, and decrease in the immune system functioning. Recently, a great deal of research has been done on the effects of SBA on cell morphology, division, apoptosis, autophagy, as well as the correlated signal transduction pathway. This review mainly covers the chemical and biological characteristics of SBA, describes the multifaceted aspects of SBA anti-nutritional functions, and highlights the possible cellular and molecular mechanism of anti-nutritional effects of SBA. This review has important implications for the prevention and treatment of… More >

Abstract Increasing evidence indicates that aberrant expressions of some microRNAs are associated with cancer progression. However, the roles and biological mechanisms of miRNA-16-5p in human non-small cell lung cancer (NSCLC) are not to be well studied. Here, we validated that the expression of miR-16-5p was decreased significantly in NSCLC samples and cell lines. The correlation between the clinicopathological features of NSCLC and the miR-16- 5p expression showed that the expression of miR-16-5p in non-small cell lung cancer was linked with the advanced TNM stage, positive lymph node metastasis, with short overall survival (OS). Also, a negative correlation between miR-16-5p and Fermitin… More >

Abstract Incorporation of etoposide (ETP) into nanoemulsion (NE) containing polyunsaturated fatty acids (PUFAs) may potentially augment its antiproliferation effect on the cancer cells. The current study aimed to examine the in vitro antitumor activity of a novel formulation (ETP-BC/EP-NE) produced by combining the anticancer drug (ETP) with NE (BC/EP-NE) consisting of the black currant seed and organic evening primrose oils. The produced formulas were physically characterized using zetasizer measurements. Their cytotoxic effect was testified at concentrations ranges from 0.0001 to 5 μM using CCK-8. Apoptotic and anti-invasion effects were evaluated using the assays of mitochondrial membrane potential, annexin V-FITC double staining,… More >

Abstract Bronchial asthma is a common chronic inflammatory disease characterized by airway hyperresponsiveness (AHR), inflammatory cell infiltration, and airway remodeling. F-box/WD repeat-containing protein 7 (FBXW7), an E3 ubiquitin ligase, is required for various endothelial functions, such as cell migration, inflammation, and endothelial integrity. This study aimed to investigate the role of FBXW7 in lipopolysaccharide (LPS)-induced epithelial barrier impairment in bronchial epithelial cells in vitro. By using lentivirus-based technology, FBXW7 was overexpressed or silenced (24 h) in human bronchial epithelial (16HBE) cells, which were treated with LPS or not (24 h). Immunoprecipitation (IP) detection and Western blot analysis were used to evaluate… More >

Abstract Apurine/pyrimidine-free endonuclease 1 (APEX1) is a multifunctional enzyme that contributes to oxidizationmediated DNA-cleaved base excision repair and redox activation of transcription factors. However, the role of APEX1 during cardiomyocyte oxidative stress injury is not completely understood. In the present study, whether APEX1 protects oxidative damage-induced cardiomyocytes was investigated. mRNA and protein expression levels of APEX1 were downregulated in the mouse model of cardiac ischemia-reperfusion injury. Furthermore, the expression of APEX1 in hydrogen peroxide (H₂O₂)-treated neonatal mice cardiomyocytes was also decreased. APEX1 knockdown aggravated H₂O₂-treated cardiomyocyte apoptosis indexes. By contrast, APEX1 overexpression reversed H₂O₂-induced oxidative damage, as demonstrated by decreased caspase… More >

Abstract Chemotherapy is widely used for non-small cell lung cancer (NSCLC) patients at a late stage; however, NSCLC patients often acquire resistance to chemotherapeutic drugs, thus limiting the therapy efficacy. Melittin, a major component of bee venom, possesses anti-tumor activity in various cancer cells. Here, we examined the effects of melittin on A549/DDP cisplatin-resistant lung adenocarcinoma cells and xenografts formed from this cell line and investigated the possible target of melittin. Treatment with melittin resulted in the induction of cell apoptosis, glycolysis inhibition, and reduction of phosphorylated AKT (p-AKT) in A549/DDP cells. We also identified that tripartite motif-containing 8 (TRIM8) was… More >

Abstract Hyperlipidemia acute pancreatitis (HLAP) is a significant cause of AP, characterized by recurrent attacks, more complications and high incidence and mortality. HLAP is often accompanied by single or multiple organ damage. Negative regulation of interferon-regulatory factor 9 (IRF9) on sirtuin-1 (SIRT1) contributes to a range of diseases. However, the function of IRF9 and SIRT1, and the relationship of the two in HLAP with heart injury remain to be illustrated so far. Animal models of HLAP were set up by feeding with high-fat chow and subsequently injecting 20% L-arginine intraperitoneally. The degree of pancreas and heart tissue injury was evaluated.

Abstract This study investigates if the anti-tumor effect of Pterostilbene in the SKOV3 ovarian cancer (OC) cell line involves inhibition of cell metabolism and tested in this effect involves modulating AMPK and Akt-induced regulation of mTORC1. Initially, SKOV3 cells were cultured in the humidified conditions in DMEM media for 24 h with or without increasing concentration of Pterostilbene. Then, the cells were incubated with Pterostilbene (IC₅₀ = 50 µM) under similar conditions with or without pre-incubation with Dorsomorphin, an AMPK inhibitor. In a dose-dependent manner, Pterostilbene inhibited SKOV3 cell survival and increased their lysate levels of lactate dehydrogenase (LDH) and single-stranded… More >
