T1001 is an antagonist of hypoxia-inducible factor-2α subunit (HIF-2α) which displaces residue M252 from inside the HIF-2α PAS-B pocket toward the ARNT subunit to weaken heterodimerization.
Apoptin-derived peptide, an antitumor polypeptide, exhibits cytotoxic effects by promoting apoptosis and necrosis in gastric cancer (GC) cells through the modulation of the PI3K / AKT / ARNT signaling pathway. It also impedes both the invasion and migration of cancer cells by inhibiting the expression and phosphorylation of the p85 subunit of PI3K, subsequently suppressing the PI3K / AKT pathway critical to gastric cancer development [1].
