Abstract Cholinergic Receptor Nicotinic Alpha 5 (CHRNA5) is an important susceptibility locus for nicotine dependency and lung cancer. Depletion of CHRNA5 has been associated with reduced cell viability, increased apoptosis and alterations in cellular motility in different cancers yet not in breast malignancy. Herein we first showed the expression of CHRNA5 was variable and positively correlated with the fraction of total genomic alterations in breast malignancy cell lines and tumors indicating its potential role in DNA damage response (DDR). Next, we exhibited Brefeldin A supplier that silencing of CHRNA5 appearance in MCF7 breasts cancer cell range by RNAi affected appearance of genes involved with cytoskeleton, TP53 signaling, DNA synthesis.
