Human Epidermal Growth Factor Receptor-2 gene polymorphism and breast cancer risk in women from the Northeastern region of Brazil

Clinics; 75 (), 2020
OBJECTIVES: In the Human Epidermal Growth Factor Receptor-2 (HER2) rs1136201 variant, the presence of the G allele may promote cellular alterations and increase breast cancer risk, in addition to enhanced cellular proliferation, tumor aggressiveness, and metastases. The aim of this study was to investiga...

Functional and genomic characterization of three novel cell lines derived from a metastatic gallbladder cancer tumor

Biol. Res; 53 (), 2020
BACKGROUND: Gallbladder cancer (GBC) is the most common tumor of the biliary tract. The incidence of GBC shows a large geographic variability, being particularly frequent in Native American populations. In Chile, GBC represents the second cause of cancer-related death among women. We describe here the es...

Association of menopausal status, expression of progesterone receptor and ki67 to the clinical response to neoadjuvant chemotherapy in luminal breast cancer

Abstract Objective To identify the biomarkers of response to neoadjuvant chemotherapy in early luminal breast cancer. Methods A cross-sectional study that included all patients with early or locallyadvanced luminal breast cancer submitted to neoadjuvant chemotherapy between 2013 and 2014. Demographic...

The ERBB2 gene polymorphisms rs2643194, rs2934971, and rs1058808 are associated with increased risk of gastric cancer

Braz. j. med. biol. res; 52 (5), 2019
Gastric cancer (GC) is the third most lethal type of cancer worldwide. Single nucleotide polymorphisms (SNPs) in regulatory sites or coding regions can modify the expression of genes involved in gastric carcinogenesis, as ERBB2, which encodes for the tyrosine-kinase receptor HER-2. The aim of this work w...

Expresión de cadherinas E y P en los tipos moleculares de cáncer de mama

Invest. clín; 56 (2), 2015
La transición epitelial-mesenquimal es un proceso mediante el cual las células tumorales pierden sus marcadores epiteliales y facilita la migración a órganos distantes. En este proceso intervienen diversas proteínas de adhesión celular, tales como la cadherina E y la cadherina P. El presente estudi...
