“…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.…”

Protein tyrosine kinases (PTKs) are essential for eukaryotic signaling. By targeting select PTKs, the group of drugs known as Tyrosine kinase inhibitors (TKIs) have proven to be effective for treating multiple diseases ranging from cancer to pulmonary fibrosis. However, some TKIs also paradoxically lead to the development of adverse conditions such as pulmonary arterial hypertension (PAH) by promoting endothelial cell dysfunction (ECD). We hypothesize that (1) subsets of PTKs may disproportionately modulate signaling pathways critical for endothelial homeostasis, such as BMPR2 signaling, and (2) inhibiting those pro-endothelial PTKs can promote the development of ECD. Herein we use an agnostic high-throughput siRNA screen to investigate how PTKs affect the canonical BMPR2 signaling pathway. Our major finding is that within the Src-family of non-receptor PTKs, the Src-B family promotes canonical BMPR2 signaling while the Src-A family suppresses it. We focus on two representative members of each family, Lck (for Src-B) and Fyn (for Src-A) that are the strongest activators or inhibitors of BMPR2 signaling in the screen. We confirm that Lck is expressed in the endothelium of pulmonary arteries and show that Lck knockout (termed si-Lck) in pulmonary artery endothelial cells (PAECs) suppresses canonical BMPR2 signaling while Fyn knockout (termed si-Fyn) promotes canonical BMPR2 signaling. Furthermore, Lck and Fyn are responsible for opposing functional behaviors in PAECs: si-Lck promotes apoptosis and interferes with tube formation while si-Fyn suppresses apoptosis and promotes tube formation. After analyzing the whole-transcriptome signature of si-Lck and si-Fyn PAECs we find that in addition to BMPR2 signaling suppression, si-Lck (and not si-Fyn) increases a broad number of ECD markers and increases canonical NF-κβ signaling. In summary, for the first time we show that Src-A and B Family of PTKs exert differential control over key endothelial cell signaling pathways resulting in direct phenotypic consequences. This knowledge may help to guide the design of more precise TKIs which avoid adverse drug reactions brought about through endothelial cell dysfunction.

“…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].…”

Cellular senescence is a cell state involved in both physiological and pathological processes such as age-related diseases and cancer. While the mechanism of senescence is now well known, its role in tumorigenesis still remains very controversial. The positive and negative effects of senescence on tumorigenesis depend largely on the diversity of the senescent phenotypes and, more precisely, on the senescence-associated secretory phenotype (SASP). In this review, we discuss the modulatory effect of nitric oxide (NO) in SASP and the possible benefits of the use of NO donors or iNOS inducers in combination with senotherapy in cancer treatment.
