FOXP2 and breast cancer: MSCs can induce fatty acid oxidation by upregulating mitofusin 2, a mitochondrial fusion-inducible factor, Carnitine Palmitoyl Transferase 1 (CPT1), and lncRNA MACC1-AS1 in gastric cancer, which finally leads to enhancement of stemness.230–232 Plus, the direct contact between MSCs and breast cancer cells upregulates the miR-199a in cancer cells, which subsequently represses the transcriptional regulator forkhead box P2 (FOXP2) and finally leads to higher stemness.233
