The SGLT2 inhibitor improves ER stress. SGLT2 inhibitor treatment inhibits the loss of GRP78 from transducers by activating Sirt1, thus inhibiting the development of ER stress. The downstream signalling pathways of PERK, ATF6 and IRE1α can induce the transcription of CHOP. CHOP upregulates the expression of the pseudokinase tribbles homologue 3 gene and weakens the inhibitory effect of AKT on the expression of caspase-9 and caspase-3. On the other hand, CHOP promotes the expression of Bax and Bak and inhibits the expression of Bcl-2, Bcl-XL and MCL-1. IRE1α also promotes apoptosis by sequentially activating ASK1 and JNK
