Vesicular trafficking-related proteins as the potential therapeutic target for breast cancer

Vesicular trafficking between endoplasmic reticulum and Golgi plays a major role in the growth and proliferation of breast cancer cells. Various proteins regulate this ER-Golgi kinetics; however, their potential as therapeutic targets in breast cancer has not been much evaluated. In the present review, we try to shed light on the implication of vesicular trafficking-related proteins like Rab family of proteins, in the pathogenesis of breast cancer via promoting cancer cell proliferation and invasion. The literature for this review was mainly searched in PubMed during the years 2014 to 2018 by using the keywords, 'breast cancer', 'breast cancer and its current treatments', 'breast cancer and vesicular trafficking', 'Rab family proteins in breast cancer', etc. Targeting proteins involved in vesicular transport like Rab GTPases, the neural precursor cell-expressed developmentally downregulated protein 9 (NEDD9), runt-related transcription factor 2 (RUNX2), human rhomboid family-1 (RHBDF1), monocarboxylate transporter 4, etc., would aid in designing improved therapeutics for the treatment of breast cancer.
