Methylation of promoter induced by SNAI2-DNMT3B complex promotes epithelial-mesenchymal transition and correlates with poor prognosis in ERα-positive breast cancers.

Estrogen receptor α (ERα) serves as an essential therapeutic predictor for breast cancer (BC) patients and is regulated by epigenetic modification. Abnormal methylation of cytosine phosphoric acid guanine islands in the estrogen receptor 1 (ESR1) gene promoter could silence or decrease ERα expression. In ERα-negative BC, we previously found snail family transcriptional repressor 2 (SNAI2), a zinc-finger transcriptional factor, recruited lysine-specific demethylase 1 to the promoter to transcriptionally suppress ERα expression by demethylating histone H3 lysine 4 dimethylation (H3K4me2).

Co-expression of VEGF-C and survivin predicts poor prognosis in esophageal squamous cell carcinoma.

Background: Lymphatic metastasis is one of the main factors affecting prognosis in esophageal squamous cell carcinoma (ESCC). Vascular endothelial growth factor-C (VEGF-C) is an important factor that promotes lymphangiogenesis. Survivin also plays a significant role in lymphatic invasion.

TRPC1 inhibits the proliferation and migration of estrogen receptor-positive Breast cancer and gives a better prognosis by inhibiting the PI3K/AKT pathway.

Purpose: Previous studies have indicated that transient receptor potential (TRP) channels can influence cancer development. The TRPC subfamily consists of seven subtypes, TRPC1 - TRPC7. Interestingly, the expression levels of TRPC1 have been shown to be totally different in different breast cancer cell lines.

[Effect of proteins extracted from mycelia of Omphalia lapidescens on inhibiting H, liver cancer in mice and regulating immune function].

Objective: To explore the effect of proteins extraceed from mycelia of Omphalia lapidescens on inhibiting H22 liver cancer in vivo.

Methods: 50 hepatoma 22 tumor bearing mice models were divided into five groups randomly:control group( CG), cyclophosphamide group, and 3 groups of incremental Hepatoma 22 dosages (5, 3, 1 mg/kg). All groups were i.

[Influence of modeling sodium on the dialysis disequilibrium syndrome in hemodialysis].

Objective: To observe the influence of modeling sodium on the dialysis disequilibrium syndrome in hemodialysis.

Methods: Sixteen patients received hemodialysis for the first time. Eight of them received the hemodialysis in the order of common sodium, modeling sodium, common sodium, and modeling sodium, whereas the other 8 patients were treated in the order of modeling sodium, common sodium, modeling sodium, and common sodium.
