Aberrant Epigenetic Reprogramming in the First Cell Cycle of Bovine Somatic Cell Nuclear Transfer Embryos.

Zygotic epigenetic reprogramming is the major initial event in embryo development to acquire a totipotent potential. However, the patterns of epigenetic modifications in bovine zygote were not well clarified, especially in the first cell cycle of bovine somatic cell nuclear transfer (SCNT) embryos. This study was conducted to examine the patterns of DNA methylation (5-methylcytosine [5mc] and 5-hydroxymethylcytosine [5hmc]) and histone H3 lysine 9 methylation (H3K9m2 and H3K9m3) in the first cell cycle of bovine fertilization (IVF) and SCNT embryos.

MiR-525-5p Repressed Metastasis and Anoikis Resistance in Cervical Cancer via Blocking UBE2C/ZEB1/2 Signal Axis.

Background: Accumulating evidence indicated that miRNAs are important regulators involved in cancer biology.

Aims: We aimed to investigate the biological functions and potentially underlying molecular mechanism of miR-525-5p in CC.

Methods: RT-PCR and Western blot assay were performed to detect mRNA and protein expression.

[Triptolide induces autophagy of ovarian granulosa cells via PI3K/AKT/m TOR pathway].

The aim of this paper was to observe the concentration,time and mechanism of autophagy induced by triptolide( TP) in ovarian granulosa cells( OGCs). CCK-8 method was used to compare the inhibitory effects of TP at different concentrations on primary cultured rat OGCs and IC50 was calculated. The effects of TP at different concentrations and time points on the expression of OGCs autophagy factor protein and the cascade of PI3 K/AKT/m TOR pathway were detected by Western blot.
