The selective knockdown of genes such as TP53, led to a decrease in G1 length and thus an overall increase in cell proliferation (Supplementary Fig. 2d) PubMed:29686391
P2X7 activation is followed by a number of downstream events, including release of pro-inflammatory mediators, cell death, and proliferation. PubMed:27314526
In VSMC pretreated with the ERK-2 inhibitor PD98059 (10 mM), migration induced by heme was partially inhibited (Fig. 3A) and heme proliferative effect on VSMC was impaired (Fig. 3B). PubMed:22954673
Carbon monoxide has vasodilatory, anti-proliferative, anti-inflammatory and antioxidant properties, whereas bilirubin, the product of biliverdin reductase, is an antioxidant (Baranano et al, 2002). PubMed:25307023
Thus, the antioxidant, anticoagulant, anti-proliferative and vasodilating effects of the HMOX1 and biliverdin reductase systems probably compensate for the nitric oxide (NO) scavenging, vasoconstrictive, proliferative, inflammatory and pro-oxidant effects of circulating free haemoglobin, haem and haem-iron, which are discussed below (Rother et al, 2005). PubMed:25307023
Heme effects were shown to be redoxsensitive, since the antioxidant Trolox (100 mM) abrogated heme-induced VSMC migration and proliferation (Fig. 1C,D). PubMed:22954673
Moreover, DPI strongly inhibited heme-induced VSMC migration (Fig. 2B) and blunted the proliferative capability of heme-treated VSMC that reached levels below the controls. (Fig. 2C), indicating that heme effects on VSMC migration and proliferation are modulated by NADPHox. PubMed:22954673
As can be observed in Fig. 1, heme has a potent chemotactic activity on VSMC (Fig. 1A), and is also a potent inducer of VSMC proliferation (Fig. 1B). PubMed:22954673

Among the redox-sensitive molecules, ERK-2, a member of MAPK family, is of crucial importance to VSMC proliferation and migration [21]. PubMed:22954673
