HOX transcript antisense intergenic RNA (HOTAIR), a well‑known long non‑coding RNA, plays an important role in the regulation of epithelial‑to‑mesenchymal transition (EMT). In this study, we propose novel mechanism through which HOTAIR promotes EMT by switching histone H3 lysine 27 acetylation to methylation at E‑cadherin promoter, induces transcriptional inhibition E‑cadherin. recruits polycomb repressive complex 2 (PRC2) catalyze H3K27me3; however, whether is associated with 27, marker...

In this paper, we propose an optimized power distribution method for hybrid electric energy storage systems vehicles (EVs). The system (HESS) uses two isolated soft-switching symmetrical half-bridge bidirectional converters connected to the battery and supercapacitor (SC) as a composite structure of protection structure. converter can precisely control charge discharge SC battery. Spiral wound SCs with mesoporous carbon electrodes are used units EVs. Under 1050 operating conditions EV...

The ubiquitin-conjugating enzyme 2C (UBE2C) is the key component in ubiquitin proteasome system (UPS) by partnering with anaphase‑promoting complex (APC/C). A high UBE2C protein expression level has been reported various types of human tumors. However, little known about precise mechanism which downregulated gastric cancer. We found MGC‑803 and SGC‑7901 cancer cells UBE2C‑deficient G2/M phase arrest cell cycle subsequently decreased adenocarcinoma tumorigenesis. In previous study, we...
