Five lactobacillus strains which were obtained from traditional fermented foods in western China, were examined for use as probiotics and for anticancer biological products. The cell walls and cytoplasm extracts from lactobacillus strains were tested for anti-proliferative activity and induction of apoptosis. The results showed the cell walls showed significant direct anticancer activity. 16S rRNA...
The current study showed that safflower yellow pigment can protect the endothelial cells, reduce the incidence of coronary restenosis, but the specific mechanisms have not been reported. Objective: To establish in vitro hemolytic blood lecithin-induced endothelial cell models of restenosis and of safflower yellow pigment on the vascular endothelial cell protection. Methods Cultured human umbilical...
To study the effect of β-ray irradiation on apoptosis in human benign hyperplastic prostate tissue. 20 BPH patients were randomly divided into 4 groups, no irradiation was applied in the control group, 90Sr/90Y β-ray individually irradiated the other 3 groups for 1 day, 4 days and 7 days. The apoptosis of human hyperplastic prostate tissues were studied by TUNEL detection, flow cytometry and agarose...
Low-power laser irradiation (LPLI), a non-damage physical therapy, which has been used clinically for decades of years, was shown to promote cell proliferation and prevent apoptosis. Apoptosis is a contributing pathophysiological mechanism of Alzheimer's disease (AD). However, whether LPLI could prevent apoptosis in AD model is not clear. In this study, we demonstrated for the first time that LPLI...
The aim of this study was to investigate the expression of Fas and Fas ligand (FasL) and to determine the signifficance of these molecules in lung cancer cell lines. Immunoblotting, RT- PCR and flow cytometric analyses were carried out to measure the expression of Fas and FasL and to examine their interactions and e.ects on cell growth and apoptosis. Fas and FasL were co-expressed in most of the cell...
In order to study mitochondria signal transduction pathway of apoptosis of SGC-7901 induced by n-butanol extract from Capparis spionosa L. (CSBE), effect of apoptosis of SGC-7901 induced by CSBE was observed. In addition, the changes of initiator, effector and marker in process of mitochondria signal transduction pathway were surveyed. The inhibitory and killing effects of SGC-7901 induced by CSBE...
To observe the effect of solanine on the membrane potential of mitochondria in HepG2 cells and [Ca2+]i in the cells, and to uncover the mechanism by which solanine induces apoptosis. HepG2 cells are double stained with TMRE and Fluo-3/AM, and both the change in membrane potential of mitochondria and that of [Ca2+]i in the cells are observed using LCSM. The results of double staining with TMRE and...
Human mitochondrial proteins are involved in fundamental biological process including apoptosis, energy production and many metabolic pathways, prediction of mitochondrial proteins is a major challenge in genome annotation. In this study, we implemented a machine learning approach and developed reliable neural network and SVM based methods to classify human mitochondria proteins with high confidence...
