TYK2 and liver cancer: Kaempferol also decreases the expression level of miR-21, cytokine signaling 3 (SOCS3), signal transducer and activator of transcription 3 (STAT3), CDK1, cyclin B, PI3K/AKT/mTOR and p-mTOR signaling pathway, and hypoxia-inducible factor 1 (HIF-1) in human hepatic cancer cells and enhanced the expression of Janus kinase 1 (JAK1), tyrosine kinase 2 (Tyk2), STAT1/2, endogenous interferon (IFN)-α-regulated genes, phosphatase and tensin homologue (PTEN), microtubule-associated protein 1A/1B-light chain 3 (LC3-II), p44/42 MAPK, beclin 1, and autophagy-related gene (Atg) 5, 7, and 12 [60,61,62,63].
