Originally characterized as the primary luteotropic signal of early pregnancy, hCG is recognized as a pleiotropic molecule investigated across reproductive endocrinology, GPCR pharmacology, steroidogenesis, immunomodulation, angiogenesis, and endometrial biology. With thousands of indexed peer-reviewed publications, hCG ranks among the most thoroughly characterized hormones in biomedical research. Key Research Highlights Research AreaKey Finding LHCGR ActivationCryo-EM structures of full-length LHCGR-hCG-Gs complex reveal "push-and-pull" activation mechanism with conserved tethered agonist peptide P10 (Duan et al., 2021, Nature) Biased AgonismhCG 5-fold more potent than LH for cAMP (EC₅₀ 107 pM vs. 530 pM); hCG biased toward sustained cAMP/PKA steroidogenic signaling vs. LH ERK1/2 preference (Casarini et al., 2012) Endometrial BiologyhCG-activated LHCGR increases HOXA10, ITGB3, FOXO1, and LIF expression; modulates autophagy via ERK1/2 and mTOR; epigenetic H3K27Ac changes at decidualization-associated genes (Wang et al., 2024; Žukauskaite et al., 2025) Research Applications GPCR biased agonism and LHCGR signaling studies Steroidogenesis and StAR protein pathway investigation Reproductive endocrinology and spermatogenesis models Endometrial receptivity and epigenetic regulation research Maternal-fetal immune tolerance investigation Angiogenesis and EG-VEGF pathway studies Research Use Only.
