We aimed to investigate the effects of grape seed extract (GSE) and vitamin E (Vit E) on oxidative stress and apoptosis in the hippocampus of streptozotocin-induced diabetic rats. In Control, Diabetic, and Diabetic treated with GSE (Diabetic+GSE) and vitamin E (Diabetic+Vit E) groups, oxidative stress index (OSI), TUNEL staining and Bcl-2, Bcl-XL, Bax, caspase-3, -9, and -8, Cyt-c, TNF-α, and NF-κB...
The shiitake mushroom Lentinula edodes has health benefits and is used to treat various diseases due to its immunomodulatory and antineoplastic properties. In the present study, the Latcripin-13 domain, isolated from L. edodes, was expressed in Escherichia coli Rosetta-gami(DE3) in the form of inclusion bodies. The Latcripin-13 domain was purified by Ni–His affinity chromatography with high purity...
The mammalian genome contains numerous genes encoding transcription factors that contain Krüppel-associated box (KRAB) and C2H2-type zinc finger (ZF) motifs (KRAB-ZF). In the present study, we identified KRAB-ZF genes expressed in the mouse testis or ovary, and selected three genes that exhibit gonad-specific or gonad-predominant expression. In vitro analyses showed that these gonadal KRAB-ZF proteins...
MicroRNAs the small (18–22 in length) noncoding RNA molecules are negative regulators of gene expression, modulating biological processes of cell differentiation, survival and death. The latter two phenomena are critical in tumour biology. We provide here the results of human genome wide target prediction of one such microRNA, hsa-miR-24-2, shown to target genes essential for initiating cellular stability...
In this study, we aimed to assess the neuroprotective effect of sevoflurane preconditioning in a cerebral focal ischemia–reperfusion rat model. Sixty Sprague Dawley rats were divided into six groups: sham operated group, cerebral focal ischemia–reperfusion (CIR) group, CIR+sevoflurane preconditioning (SP) (2%) group, CIR+sevoflurane preconditioning (2.5%) group, CIR+sevoflurane preconditioning (3%)...
In addition to its actions outside the cell, cellular uptake and nuclear import of insulin-like growth factor binding protein-3 (IGFBP-3) has been recognized for almost two decades, but knowledge of its nuclear actions has been slow to emerge. IGFBP-3 has a functional nuclear localization signal and interacts with the nuclear transport protein importin-β. Within the nucleus IGFBP-3 appears to have...
Achilles tendon pathology (ATP) is a degenerative condition which exhibits excessive tenocyte apoptosis. Tumour necrosis factor receptor 1 (TNFR1), caspase-3 (CASP3) and caspase-8 (CASP8) are important regulators of apoptosis. To date, the effects of variation within the genes for TNFR1 and CASP3 as risk factors for ATP have not been described. There is evidence that two single nucleotide polymorphisms...
Systemic therapy with cytotoxic agents provides marginal benefit in hepatocellular carcinoma (HCC) treatment especially for patients with advanced HCC. Cisplatin is one of the most active cytotoxic agents for HCC treatment. However, acquisition of cisplatin resistance is common, and one important underlying mechanism of such resistance is apoptosis-resistance. In this study, we found that miR-363...
Ubiquitin-specific protease 22 (USP22) can regulate the cell cycle and apoptosis in many cancer cell types, while it is still unclear whether the deubiquitinating enzyme activity of USP22 is necessary for these processes. As little is known about the impact of USP22 on the growth of HeLa cell, we observed whether USP22 can effectively regulate HeLa cell growth as well as the necessity of deubiquitinating...
Gene therapy, a significantly crucial strategy for treatment of malignancies, has been gradually accepted in recent years. However, this therapeutic approach has being facing great challenges concerning problems which include complicated development of cancer with multiple gene control, effective target shortage, low efficiency of gene transferring and safety of the vector delivery system. Shepherdin,...
To investigate the role of miR-221/222 in cell proliferation and apoptosis in human prostate cancer cells, and examine the effects of miR-221/222 on caspase-10 expression.Prostate cancer cells were transfected with miR-221/222 mimics or inhibitors. Cell proliferation was assessed by MTT assay. The expression levels of miR-221/222 were detected with quantitative real-time PCR. Apoptosis was induced...
Glioblastoma is the deadliest brain tumor in humans. Recent studies suggested that 5-aza-2-deoxycytidine (AzaC) could inhibit cell cycle progression in human glioblastoma stem cells by an indirect increase in expression of the tumor suppressor microRNA-137 (miR-137). Delphinidin (DPN), a new anthocyanidin, inhibits cell growth in different cancers. We investigated inhibition of glioblastoma growth...
