SCD and gastric cancer: SIRT6 inhibited the malignant progression of GC by activating the Keap1/NRF2 signaling pathway and upregulating the expression of GPX4.[98] Further, GC cells enhanced their SCD1 expression by secreting exo‐lncFERO into GC stem cells (GCSCs), which inhibited the expression of ferritin by directly interacting with SCD1 mRNA or by recruiting hnRNPA1.
