Key resistance pathways include: lactylated IGF2BP3 activating PCK2-NRF2 to counter lenvatinib-induced stress; ALDOA lactylation enhancing liver cancer stem cell self-renewal for chemoresistance; MOESIN lactylation in Regulatory T cells (Tregs) weakening anti-PD-1 efficacy. This evidence concerns the gene IGF2BP3 and liver cancer.
