Specifically, previous research on the Mia PaCa‐2 pancreatic cancer cell line has shown that SFN suppresses the expressions of heat shock protein 90 (Hsp90) and its associated proteins, including Akt, cyclin‐dependent kinase 4 (CDK4), and p53, while stimulating the activity of cysteine aspartase (caspase)‐3 to exhibit anti‐cancer effects [10]. Here, CDK4 is linked to cancer.
