Alternative splicing of synuclein gamma in endometrial cancer: identification of a novel isoform.

ABSTRACT: Synuclein gamma (SNCG) is under consideration as a potential biomarker in cancer biology. Up to date four different SNCG variants are described. Due to growing evidence suggesting correlations between aberrant alternative splicing processes and cancer progression, we investigated the effects of peritumoural conditions on expression pattern of SNCG in endometrial cancer (EC) in vitro. Compared to breast cancer cell lines, mRNA expression levels of all known SNCG isoforms 1-4 are significantly reduced in EC cell lines. We identified a novel alternatively spliced variant of isoform 2 (isoform 2 short) which is found highly expressed in EC cell lines. Hypoxia and acidosis trigger an up-regulation of isoform 2 short. EC cell lines are characterized by low SNCG protein levels under control condi
