Although ginkgo biloba extract (GBE) was shown to have antioxidant effects, little has been reported on the ability to GBE to help endothelial progenitor cells (EPCs) resist oxidative stress. The present study evaluated the influence of different concentrations of GBE on superoxide dismutase (SOD) and apoptosis of diabetic peripheral blood EPCs. Twenty-five diabetic patients without any ... more
Isoflurane can induce widespread cytotoxicity. We hypothesized that isoflurane induces apoptosis partly by causing excessive calcium release from the endoplasmic reticulum (ER) via direct activation of inositol 1,4,5-trisphosphate receptors (IP3R). Rat pheochromocytoma cells cultured for seven days with nerve growth factor were divided into four groups: control group (C), IP ... more
In several species, placentation involves the presence of two different membranes responsible for maternal-fetal exchanges: the yolk sac and the chorioallantoic placenta. The yolk sac plays important roles in embryonic survival, mainly during the early stages of gestation. In bovine, it is a transitional membrane that is present until day 50-70 of pregnancy. Herein, we evaluated the ... more
We explored whether p53 upregulated modulator of apoptosis (PUMA) gene transfection could enhance the sensitivity of epirubicin-induced apoptosis of MCF-7 breast cancer cells. The liposome-mediated recombinant eukaryotic expression vector PUMA-pCDNA3 and empty vector plasmid were stably transfected into MCF-7 cells. Epirubicin (0.01-100 μM) was applied to MCF-7, MCF-7/PUMA, and ... more
We observed the influence of different concentrations of Rhizoma paridis total saponins (RPTS) on the apoptosis of colorectal cancer cells and explored the internal mechanism involved. We determined whether RPTS influences the interleukin-6 (IL-6)/Janus kinase (JAK)-signal transducer and activator of transcription-3 (STAT3) apoptosis molecular pathway and looked for colon cancer ... more
Swainsonine (SW), an extract from Astragalus membranaceus, represents a new class of compounds that inhibit growth and induce apoptosis in a cancer model. In this study, we demonstrated the effect of Fyn on SW-induced apoptosis in 293T cells. Western blotting was used to measure the expression of the apoptosis-related factors caspase-3, Bcl-2, Bax, and the key factor Akt (also ... more
Rat liver regeneration (RLR) induced by partial hepatectomy involves cell proliferation regulated by numerous factors, including microRNAs (miRNAs). miRNA high-throughput sequencing has been established and used to analyze miRNA expression profiles. This study showed that 39 miRNAs were related to RLR through the analysis of miRNA high-throughput sequencing. Their role toward rat normal ... more
The objective of this study was to observe the acute cytotoxic effects of hematoporphyrin monomethyl ether sonodynamic therapy (HMME-SDT) on hypertrophic scar fibroblasts of rabbit ears. We first assessed the effects of different irradiation times and HMME concentrations on the survival of hypertrophic scar fibroblasts using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium ... more
We investigated the effect of p38MAPK/AP-1 (activator protein-1) signaling on the apoptosis of osteoblasts induced by high glucose. A lentivirus vector of small hairpin RNA (shRNA) targeting p38MAPK was constructed in vitro. Osteoblasts MC3T3-E1 cultured in vitro were treated with vehicle, high glucose, p38MAPK-shRNA transfection, p38MAPK inhibitor, and unrelated shRNA ... more
We examined the effect of transforming growth factor-b inducible early gene-1 (TIEG1) on the apoptosis of leukemic cell lines and expression of B-cell lymphoma 2 (Bcl-2) and phosphatase and tensin homolog (Pten). Four leukemic cell lines (HL-60, U937, Raji, and K562) were treated with 0, 1, 5, 10, and 20 ng/mL TIEG1, respectively. The cell growth inhibitory ratio was assessed using the ... more
