1 Further studies were performed to determine whether human chorionic gonadotropin (hCG) can interact with the insulin-like growth factor-I (IGF-I) signaling pathway to increase tyrosine phosphorylation of IRS-I. Tyrosine hypertrichosis 2 (generalised, congenital) Homo sapiens
2 The increased tyrosine phosphorylation of IRS-I seen in response to IGF-I stimulation following treatment with either hCG or forskolin was not due to an increase in IRS-I content. Tyrosine hypertrichosis 2 (generalised, congenital) Homo sapiens
3 Thus, we conclude that hCG/LH and IGF-I signaling pathways "cross-talk" to increase the levels of IRS-I tyrosine phosphorylation. Tyrosine hypertrichosis 2 (generalised, congenital) Homo sapiens
