Comparison of these selective PDIA1 inhibitors with E64FC26; a potent pan‐style inhibitor which inhibits; PDIA1, PDIA3, PDIA4, PDIA6 and TXNDC5, would give an indication as to whether inhibition of PDIA1 alone is sufficient for suppressing cancer cell growth.54 The gene discussed is PDIA4; the disease is cancer.
