Inhibition of α-enolase affects the biological activity of breast cancer cells by attenuating PI3K/Akt signaling pathway.

This study aimed at exploring the role of α-enolase (ENO1) in proliferation, invasion, and cell apoptosis in MDA-MB-231 and MCF-7 breast cancer human cells, to provide a theoretical basis for the clinical treatment of breast cancer. MATERIALS AND METHODS: MDA-MB-231 and MCF-7 cells were randomly divided into five groups: normal control group (Control group), negative control group (negative control virus, NC group), and shENO1 (sh1, sh2, and sh3) group, respectively. The expressions of ENO1 mRNA and protein were measured by Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) and Western blot, respectively. Cell proliferation, cell invasion ability, and cell apoptosis rate were detected by methyl thiazolyl tetrazolium (MTT) assay, transwell invasion assay, and flow cytometer, respectively. The expressions of the proteins correlated with phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway were analyzed by Western blot. RESULTS: In MDA-MB-231 and MCF-7 cells, the gene and protein expressions of ENO1 in the three sh groups in MDA-MB-231 and MCF-7 cells were significantly lower than those in control group and NC group. In MDA-MB-231 and MCF-7 cells, the gene and protein expressions of ENO1 in the three sh groups were significantly lower than those in control group and NC group. Compared with NC group, the proliferation activity, invasion ability, and apoptosis rate of shENO1 group were significantly decreased (p

CONCLUSION: The best of our knowledge it is the third description of brachial plexus schwannoma associated with breast cancer and the first with a synchronous association. The knowledge of this pathology and its potential to alter treatment justify the reporting of the present case. PMID: 32083563 [PubMed - as supplied by publisher]

In spite of attempts to classifying breast cancer according to its histological and molecular properties, it is almost considered as a dilemma in treatment. Nowadays, public and medical attentions have primary focused on foods with anti-cancer properties to alleviate the cancer problems. Flavonoid components such as Quercetin (Qu) as dietary substances with high attention of ordinary people might provide potentia...

Authors: Shiroma PR, Velasquez T, Usset TJ, Wilhelm JH, Thuras P, Baltutis E Abstract INTRODUCTION: Obesity is prevalent among users of Veteran's Health Administration services, where it is comorbid with depression, post-traumatic stress disorder, type 2 diabetes, cardiovascular disease, colon, and breast cancer. Among obese subjects, severe obesity represents a subpopulation with the highest risk of depression. We investigate the antidepressant effect of a local VA weight management program (Managing Overweight Veterans Everywhere - MOVE) among depressed veterans with severe obesity. MATERIAL AND METHODS: In a...

We describe below a patient who has shown a response to combination of chemotherapy with Elenagen, a plasmid encoding p62. Elenagen was tested in a previous phase I/II study in patients with refractory solid tumors and shown to be safe. Also, plasmid ability to halt tumor progression and restore sensitivity to chemotherapy was found. Preclinical data supports effects on tumor grade and change the tumor's microenvironment in spontaneous canine breast cancers. We describe here a 48-year old female with triple-negative and BRCA1/2-negative breast cancer who had a primary resistance to chemotherapy and negative dynamics despit...

TahtamouniAbstractCephalostatin 1, a potent anti-cancer agent, is a natural bis-steroidal alkaloid that causes cell death in the subnanomolar to picomolar ranges via an atypical apoptosis pathway. Although cephalostatin 1 is a highly effective anticancer drug, its availability limits its utilization. We previously reported the synthesis of two 12'α-hydroxy derivatives of cephalostatin 1 that induce cell death by activating the ER str...
