1 A selective beta2AR antagonist mirrored propranolol"s effects on HemSCs in a dose-dependent fashion, and a selective beta1AR antagonist had no effect, supporting a role for beta2AR signaling in IH pathobiology. Propranolol adrenoceptor beta 2 Homo sapiens
2 We have thus demonstrated that propranolol acts on HemSCs in IH to suppress proliferation and promote apoptosis in a dose-dependent fashion via beta2AR perturbation, resulting in reduced cAMP and MAPK activation. Propranolol adrenoceptor beta 2 Homo sapiens
3 Furthermore, propranolol acts via perturbation of beta2AR, and not beta1AR, although both receptors are expressed in HemSCs. Propranolol adrenoceptor beta 2 Homo sapiens
