LGALS1 and breast carcinoma: Interestingly, a similar expression pattern in the different breast cancer subtypes was identified for some genes that we found co-regulated or regulated by ERO1 in our in vitro studies and belonging to the angiogenesis (VEGFA, SERPINE1, MMP1, LGALS1, TGFB1, TFRC, PLAU), to the PERK/ATF4/CHOP pathway of UPR (PERK/EIF2AK3, ATF4, CHOP/DDIT3 and EIF2 alpha/EIF2S1) and the ERO1’s cognate, PRDX4 [17].
