These transcriptional pathways coordinate PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/26757549 a program of hypertrophic gene expression that incorporates reactivation of fetal ventricular gene expression profiles and enhanced expression of downstream targets for example BNP and bMyHC, Coupled with preceding proof that PPARg ligands attenuate PH and activation of proliferative pathways within the lung and pulmonary vasculature,, these findings recommend that PPARg activation may represent a novel therapeutic intervention which will attenuate pathobiological derangements in each pulmonary vascular and RV signaling. As previously reported, employing the present mouse model of hypoxiainduced PH, treatment with the PPARg ligand, rosiglitazone, attenuated hypoxic increases in RVSP,RVH, and pulmonary vascular remodeling. Within the rat model of hypoxiainduced PH, in one particular study therapy with rosiglitazone attenuated hypoxiainduced RV hypertrophy and pulmonary vascular remodeling but not increases in RVSP, whereas in other folks, therapy with rosiglitazone attenuated hypoxiainduced increases in RVSP and pulmonary vascular remodeling but not increases in RVH Remedy with PPARg ligands also attenuated experimental PH and RV hypertrophyin ApoEmice caused by higher fat diets; in rats triggered by monocrotaline; or in rats treated with VEC-162 custom synthesis hypoxia or monocrotaline. The variations in responses to PPARg ligands amongst these models is probably attributable 
to differences in dosing, route, or duration of treatment, the species studied (mouse versus rat), and stimulus utilized to provoke PH. The present report extends those studies to demonstrate that pioglitazone also attenuates hypoxiainduced increases in Targeting PPARc to attenuate suitable ventricular hypertrophyChaudhry et al.Fig. Chronic hypoxia will not induce LVH or LV cardiomyocyte hypertrophy.
