BCL2 and plasma cell myeloma: In our study, using mRNA sequencing, IPA pathway analysis, and western blotting, we showed that CLF treatment induces the proteins involved ER stress pathway, including the ER stress sensors inositol-requiring enzyme 1 (IRE1), PKR-like ER kinase (PERK, EIFA2K3), and activating transcription factor 6 (ATF6), as well as the proteins involved in autophagy in myeloma, which in turn results in induction of apoptosis through the mitochondria-mediated pathway and BCL2-family proteins.
