Alternative polyadenylation (APA) generates transcript isoforms with different 3’UTR lengths due to selection of one of several poly(A) signals on pre-mRNAs. Given that these isoforms may be differentially regulated by trans factors, consequences of deregulated APA could be important, especially in cancers. Earlier, we identified SNX3 (sorting nexin 3) as an APA regulated mRNA. SNX3 binds to endosomal phospholipids and has a role in receptor recycling. We hypothesized SNX3 proteins levels to be deregulated by APA and that might have consequences in receptor dynamics in cancers. We developed SNX3 silenced cell line models to examine the phenotypical consequences. We examined known receptor cargo molecules to test for their dependencies on SNX3 mediated receptor recycling. Our results suggest SNX3 to have a pivotal role in modulating receptor levels and that may have important consequences in cellular signaling pathways. Our future work will aim to better understand the consequences of regulated APA and how SNX3 might regulate neoplastic phenotypes
