HER2/ErbB2 activates HSF1 and thereby controls HSP90 clients including MIF in HER2-overexpressing breast cancer

Generation of CHO Stable Cell Line Overexpressing HER2: an In Vitro Model for Breast Cancer

Background: Breast cancer is the most common female malignancy and the leading cause of cancer mortality in women worldwide. The human epidermal growth factor receptor2 (HER2) is a transmembrane tyrosine kinase receptor that is usually overexpressed in human breast cancers. Stable cell lines heterogeneously overexpressing HER2 are highly required as in vitro models for breast cancer research. T...

Treatment of HER2-overexpressing breast cancer.

The HER family of receptors consists of four closely related type 1 transmembrane TK receptors: HER1 (EGFR), HER2, HER3 and HER4. Signalling via the HER family of receptors underpins the majority of the intricate array of cellular activities on which cell survival and functionality depend. Aberrant HER2 expression and/or functionality have been implicated in the evolution of breast cancer and t...

Molecular Mechanisms of Trastuzumab Resistance in HER2 Overexpressing Breast Cancer

The epidermal growth factor receptor 2 (HER2) is a tyrosine kinase overexpressed in nearly 20% to 25% of invasive breast cancers. Trastuzumab is a humanized monoclonal antibody that targets HER2. The majority of patients with metastatic breast cancer initially respond to trastuzumab, however, within 1 year of treatment disease progresses. Several molecular mechanisms have been described as cont...

Novel Therapeutic Strategies and Combinations for HER2-Overexpressing Breast Cancer

MicroRNA and HER2-overexpressing Cancer

The discovery of microRNAs (miRNAs) has opened up new avenues for studying cancer at the molecular level, featuring a post-genomic era of biomedical research. These non-coding regulatory RNA molecules of ~22 nucleotides have emerged as important cancer biomarkers, effectors, and targets. In this review, we focus on the dysregulated biogenesis and function of miRNAs in cancers with an overexpres...
