Fibroblast activation protein (FAP), an integral membrane serine protease, is found on fibro- and osteo-sarcoma and on myofibroblasts in epithelial carcinoma, but rarely on other adult tissue. FAP has been demonstrated to be an excellent target for tumor imaging in clinical trials, and antibodies and other FAP-targeting drugs are in development. Here we have shown that FAP overexpression increased...
Lipotoxicity plays a vital role in development and progression of type 2 diabetes. Prolonged elevation of free fatty acids especially the palmitate leads to pancreatic β-cell dysfunction and apoptosis. Curcumin (diferuloylmethane), a polyphenol from the curry spice turmeric, is considered to be a broadly cytoprotective agent. The present study was designed to determine the protective effect of curcumin...
A number of effective anti-cancer drugs contain either indole or quinoline group. Compounds fused indole and quinoline moieties altogether as indolylquinoline were rarely reported as anti-cancer agents. We reported here that a synthetic indolylquinoline derivative, 3-((7-ethyl-1H-indol-3-yl)-methyl)-2-methylquinoline (EMMQ), inhibited the growth of human non-small cell lung cancer (NSCLC) cells in...
Epigenetic abnormalities are associated with non-small cell lung cancer (NSCLC) initiation and progression. Epigenetic drugs are being studied and in clinical trials. However, the molecular mechanism underlying the apoptosis by the epigenetic agents remains unclear. SUV39H1 is an important methyl-transferase for lysine 9 on histone H3 and usually related to gene transcriptional suppression, and chaetocin...
The execution phase of apoptosis involves many processes which modify cellular molecules for an efficient and quiet elimination of the dead cell. These include exposure and secretion of “eat-me” signals, to attract phagocytes, as well as degradation of immune-stimulating cell debris. During this phase apoptotic microparticles (MPs) are released from the dying cell. The remaining cell remnant forms...
The main purpose of this study was to investigate effect of salidroside (Sal) on myocardial ischemia reperfusion injury in rats and the underlying mechanism. Myocardial ischemia reperfusion injury (MI/RI) model was treated with 30 min of left anterior descending (LAD) occlusion followed by 24 h of reperfusion. The male Sprague–Dawley rats were randomly divided into 7 groups: (1) Sham; (2) Sham + diltiazem...
Apoptosis is essential for normal development and the maintenance of homeostasis. It plays a necessary role to protect against carcinogenesis by eliminating damaged cells. Many studies have demonstrated that the dysregulation of apoptosis results in cancer and this provides an approach to develop therapeutic agents via inducing apoptosis. In our previous studies 4β-cinnamido linked podophyllotoxin...
The acylphloroglucinols hyperforin (Hypf) and myrtucommulone A (MC A) induce death of cancer cells by triggering the intrinsic/mitochondrial pathway of apoptosis, accompanied by a loss of the mitochondrial membrane potential and release of cytochrome c. However, the upstream targets and mechanisms leading to these mitochondrial events in cancer cells remain elusive. Here we show that Hypf and MC A...
Apoptosis has been postulated to play an important role during feline infectious peritonitis virus (FIPV) infection; however, its mechanism is not well characterized. This study is focused on apoptosis and transcriptional profiling of FIPV-infected cells following in vitro infection of CRFK cells with FIPV 79-1146 WSU. Flow cytometry was used to determine mode of cell death in first 42 h post infection...
Heat has been used as a medicinal and healing modality throughout human history. The combination of hyperthermia (HT) with radiation and anticancer agents has been used clinically and has shown positive results to a certain extent. However, the clinical results of HT treatment alone have been only partially satisfactory. Cell death following HT treatment is a function of both temperature and treatment...
