In vitro and in vivo evaluation of dasatinib and imatinib on physiological parameters of pulmonary arterial hypertension

Abstract: The results of these studies indicated that dasatinib did not induce physiological changes or molecular signatures consistent with PAH when compared to positive controls. Instead, dasatinib induced changes consistent with imatinib. Both dasatinib and imatinib induced biochemical and structural changes consistent with a protective effect for PAH. These data suggest that other factors of unclear etiology contributed to the development of PAH in patients treated with dasatinib.

“…The extreme differences in terms of effects on pulmonary circulation between imatinib and dasatinib suggest that dasatinib-induced pulmonary vascular toxicity is molecule-related rather than class-related. On the other side, in vivo and in vitro studies aimed at evaluating the effects of dasatinib and imatinib on pulmonary vasculature demonstrated that both TKI increased levels of nitric oxide, a potent vasodilator, without inducing PAH-related adverse remodeling, thus suggesting that both the drugs could promote beneficial effects for PAH [48]. These results are in contrast with the clinical evidence of dasatinibinduced PAH.…”

“…Specifically, Fyn has been studied in endothelial and smooth muscle cells [27,28] while Lck is traditionally believed to exist in T-Cells and to a lesser degree NK-Cells. It is only more recently that we and other have shown Lck is expressed in PAECs and HUVECs, respectively [25,29]. It remained unknown if Lck was present at a protein or message level in the pulmonary endothelium of human lungs, or if it was altered in disease.…”

“…Many modifications can be induced by these two senolytic drugs of NO levels. Indeed, dasatinib can induce an increase in plasma NO in pulmonary artery and smooth muscle cells [124]. Additionally, Hu et al (2018) recently found that Src inhibition by dasatinib increases iNOS, a pro-inflammatory macrophage marker, in both intestinal and bone marrow-derived macrophages [125].…”
