Abstract Background Anoikis resistance plays a critical role in the tumor metastasis by allowing survival of cancer cells systemic circulation. We previously showed that long non-coding RNAs APOC1P1-3 (lncRNA APOC1P1-3) inhibit apoptosis breast cells. In this study, we explored its anoikis resistance. Methods induced two cell lines (MCF-7 and MDA-MB-231) under anchorage-independent culture cond...

ceramide as a second messenger is a key regulator in apoptosis and cytotoxicity. ceramide-metabolizing enzymes are ideal target in cancer chemo-preventive studies. neutral sphingomyelinase (nsmase), acid ceramidase (acdase) and glucosyl ceramide synthase (gcs) are the main enzymes in ceramide metabolism. silymarin flavonolignans are potent apoptosis inducers and silibinin is the most active com...

objective(s):higher cellular reactive oxygen species (ros) levels is important in reducing cellular energy charge (ec) by increasing the levels of key metabolic protein, and nitrosative modifications, and have been shown to damage the cardiac tissue of diabetic mice. however, the relation between energy production and heart function is unclear. materials and methods:streptozotocin (stz, 150 mg/...

Phenethyl isothiocyanate (PEITC) is a natural product that is among the most effective cancer chemopreventive agents known. Mechanistic studies indicate that the chemopreventive activity of PEITC is associated with its favorable modification of carcinogen metabolism and its induction of apoptosis. Here, we found that PEITC blocks tumor promoter (12-O-tetradecanoylphorbol-13-acetate or epidermal...

Hepatic dysfunction is a feature of dengue virus (DENV) infection. Hepatic biopsy specimens obtained from fatal cases of DENV infection show apoptosis, which relates to the pathogenesis of DENV infection. However, how DENV induced liver injury is not fully understood. In this study, we aim to identify the factors that influence cell death by employing an apoptosis-related siRNA library screenin...

Epithelial cell injury and apoptosis are recognised as early features in idiopathic pulmonary fibrosis and bleomycin-induced fibrosis in mice. Telomerase is a known apoptosis-alleviating factor. The role of telomerase was studied during bleomycin-induced lung epithelial cell (LEC) apoptosis in vitro in a mouse LEC line, and in vivo in LECs isolated from bleomycin-treated mice. The current autho...

Arylnaphthalene lignan lactones have attracted considerable interest because of their anti-tumor and anti-hyperlipidimic activities. However, to our knowledge, few studies have explored the effects of these compounds on human leukemia cell lines. In this study, five arylnaphthalene lignans including 6'-hydroxy justicidin A (HJA), 6'-hydroxy justicidin B (HJB), justicidin B (JB), chinensinaphtho...

To investigate the mechanism of baicalein in inducing human cervical cancer cell line C33A apoptosis. Baicalein (200 µM) was used to treat C33A cells. Cell proliferation was tested by the MTT assay. Cell apoptosis was detected by the TUNEL assay and caspase‑3 activity measurement. Cell cycle was determined by flow cytometry and associated gene expression at mRNA and protein levels. Nuclear fact...
