Comment on “Targeting AMPK, mTOR and β-Catenin by Combined Metformin and Aspirin Therapy in HCC: An Appraisal in Egyptian HCC Patients”

Abdelmonsif et al.  have recently reported that hepatocellular carcinoma (HCC) tends to exhibit higher levels of phosphorylated AMP-activated protein kinase (AMPK), phosphorylated mammalian target of rapamycin (mTOR), and β-catenin expression than pre-malignant conditions of cirrhosis. Notably, the combination of metformin and aspirin shows anti-tumor effect in HepG2 cells, with decreased levels of mTOR/AMPK and Wnt/β-catenin signal pathways. Given that metformin has been used for the treatment of type 2 diabetes mellitus and aspirin is one of the non-steroidal anti-inflammatory drugs (NSAIDs), this research holds much promise in terms of drug repositioning (DR) [1, 2]. Terfenadine, a histamine H1receptor antagonist, has been used for a long period to treat autoimmune disorders such as allergic dermatitis. In a typical DR therapeutic strategy, terfenadine suppresses the invasive and metastatic potentials of malignant melanoma. Mechanistically, terfenadine induces reactive oxygen...
