Furthermore, lipid β-oxidation and mitochondrial OxPhos were crucial for tumor repopulation of regressed pancreatic tumors in vivo (Viale et al., 2014); for in vivo age-related resistance to BRAF/MEK inhibition of melanoma (Alicea et al., 2020); and for anoikis resistance and tumor progression in ovarian cancer (Sawyer et al., 2020). The gene discussed is MAP2K7; the disease is neoplasm.
