The half inhibitory concentration (IC50) of total alkaloids on HeLa cell lines was detected via the preliminary experiment, the influences of total alkaloids at different concentrations on the proliferation of HeLa cell lines were detected via methyl thiazolyl tetrazolium (MTT) assay, and the cell growth curve was plotted. Moreover, the cell cycle and apoptosis after treatment with total alkaloids at different concentrations were detected via flow cytometry, and the caspase-3 gene and protein expressions were detected via reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting. The IC50 of total alkaloids in Caulis Mahoniaeon HeLa cell lines was 12.5 μg/mL. With the gradual increase of concentration of total alkaloids in the treatment of cervical cancer cells, the inhibitory rate on cancer cells was gradually increased, and the proportion of cells in the G0/G1 phase was gradually decreased, while that in S and G2/M phases was gradually increased. Besides, with the increase in the concentration of total alkaloids, the apoptotic rate of cervical cancer cells was gradually increased, and both caspase-3 gene and protein expressions were also gradually increased.

The response surface methodology was applied to optimize and determine the interaction among the process variables in bacteriocin production by Lactobacillus plantarum and determine their optimum levels. Chloroform-Methanol (2:1 v/v) was used for crude bacteriocin extraction through the liquid-liquid extraction method, and its antimicrobial activity was assessed.

This study investigated the fundamental molecular function of the TALNEC2 in the pathogenesis of cerebral infarction to provide insights on the potential novel therapeutic agents in cerebral infarction. RT-qPCR measured expression of TALNEC2 and JNK in human neural cell line SH-SY5Y. Cell transfection upregulated or silenced the genes with MTT assay examining cell viability. RT-qPCR detected cell death in the apoptosis biomarker caspase-3, inflammation in the biomarkers C-reactive protein (CRP) and IL-6 and verified cell proliferation via the ki67 and PCNA markers. Luciferase assay was performed to see the luciferase activity and western blotting determined the protein expression of JNK in proliferation, inflammation. The results demonstrated that TALNEC2 was highly expressed after OGD/R treatment in nerve cells after cerebral infarction. In addition, TALNEC2 silencing prevented apoptosis and inflammation of nerve cells after cerebral infarction. TALNEC2 directly interacted with miR-19a-3p to regulate JNK protein expression. Lastly, miR-19a-3p inhibitor abolished the protective effect of si-TALNEC2 against OGD/R induced damage in vitro. In summary, this study has demonstrated that TALNEC2 is a positive moderator for pathogenesis of cerebral infarction. Furthermore, our conclusions provide further insights on the interplay among TALNEC2, miR-19a-3p and JNK in cerebral infarction.

Here we analyze these potential CRC biomarkers in a Mexican population. In this study, 124 patients with sporadic CRC and 37 healthy individuals were examined as a reference group. The ccfDNA was isolated from plasma samples of all included subjects. The ccfDNA concentration was determined by fluorometry and the integrity index (ALU247/ALU115 ratio) by quantitative PCR amplification (qPCR) of ALU sequences. The results show that ccfDNA concentration was higher in CRC patients than in the reference group (P=0.001). The integrity index showed no significant differences between these groups (P=0.258), except for histological type (P=0.012). A higher ccfDNA concentration was also associated with patients younger than 50 years (P=0.030). The ccfDNA concentration showed significant discriminatory power (AUC: 0.854, C.I.: 0.78-0.92, P=0.001) between patients and the reference group and between tumor-node-metastasis (TNM) stages.

This study aims to investigate the alleviating effect of TFPFC on brain neurological impairment and its influences on Nuclear factor E2-related factor 2 (Nrf2) and heme oxygenase 1 (HO-1) expressions in rats with Ischemia-Reperfusion. The rat model of Ischemia-Reperfusion was established, and rats were treated with TFPFC or normal saline.

The influences of TFPFC treatment on the proliferative activity and apoptosis of oxygen and glucose deprivation/reoxygenation (OGD/R) neural stem cells were detected via methyl thiazolyl tetrazolium (MTT) assay and flow cytometry. Moreover, the malondialdehyde (MDA) level and superoxide dismutase (SOD) activity were measured to evaluate the oxidative stress effect. The influences of TFPFC treatment on the protein and messenger ribonucleic acid (mRNA) expressions of Nrf2 and HO-1 were analyzed using reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting.
