Breast cancer is the most common malignancy among the women worldwide, causing half a million death annually. Invasive ductal carcinoma of the milk duct (IDC) represents up to 70% of all the breast cancers. Abnormal expression of human epidermal growth factor receptor 2 (HER2), estrogen receptor (ER) and progesterone receptor (PR) has been linked to a subset of breast cancers. However, an increasing number of patients do not express HER2, ER or PR and are known as triple negative breast cancer (TNBC). TNBCs are highly aggressive, untreatable by hormone or ani-HER2 therapy, and overall have a poor survival.
The genetic alterations behind TNBC development and progression are not well understood. Our goal is to understand the molecular mechanism(s) of TNBC with a view to develop suitable TNBC management strategies.
Endophilins are a family of proteins involved in clathrin mediated vesicular endocytosis and frequently altered in various cancers and implicated in biomarker development. Our laboratory is examining the potential role of these endophilins in breast cancer. We are also examining the potential role of various miRNAs and mitochondrial energy reprogramming in breast cancer.
