Transcriptome-based repurposing of apigenin as a potential anti-fibrotic agent targeting hepatic stellate cells. Sci Rep 2017; 7:42563.

Abstract
We have used a computational approach to identify anti-fibrotic therapies by querying a transcriptome. A transcriptome signature of activated hepatic stellate cells (HSCs), the primary collagen-secreting cell in liver, and queried against a transcriptomic database that quantifies changes in gene expression in response to 1,309 FDA-approved drugs and bioactives (CMap). The flavonoid apigenin was among 9 top-ranked compounds predicted to have anti-fibrotic activity; indeed, apigenin dose-dependently reduced collagen I in the human HSC line, TWNT-4. To identify proteins mediating apigenin's effect, we next overlapped a 122-gene signature unique to HSCs with a list of 160 genes encoding proteins that are known to interact with apigenin, which identified C1QTNF2, encoding for Complement C1q tumor necrosis factor-related protein 2, a secreted adipocytokine with metabolic effects in liver. To validate its disease relevance, C1QTNF2 expression is reduced during hepatic stellate cell activation in culture and in a mouse model of alcoholic liver injury in vivo, and its expression correlates with better clinical outcomes in patients with hepatitis C cirrhosis (n = 216), suggesting it may have a protective role in cirrhosis progression.These findings reinforce the value of computational approaches to drug discovery for hepatic fibrosis, and identify C1QTNF2 as a potential mediator of apigenin's anti-fibrotic activity.

Abstract
BACKGROUND The present study has been designed to investigate the effect of sodium cromoglycate and ketotifen, mast cell stabilizers in hyperhomocysteinemia-induced cardiac hypertrophy in rats. METHODS Rats were administered L-methionine (1.7 g/kg/day PO) for 8 weeks to produce hyperhomocysteinemia. Sodium cromoglycate (24 mg/kg/day IP) and ketotifen (1mg/kg/day IP) treatments were started from first day of administration of L-methionine and continued for 8 weeks. The development of cardiac hypertrophy was assessed in terms of measuring mean arterial blood pressure (MABP), ratio of left ventricular (LV) weight to body weight (LVW/BW), LV wall thickness (LVWT), LV protein content, and LV collagen content. Further, the oxidative stress in heart was assessed by measuring lipid peroxidation, superoxide anion generation, and reduced glutathione (GSH). Moreover, the cardiomyocyte diameter and LV mast cell density were determined using hematoxylin-eosin and toluidine blue staining, respectively. RESULTS The L-methionine administration produced hyperhomocysteinemia, which significantly increased MABP, oxidative stress, and density of mast cells and consequently produced cardiac hypertrophy by increasing cardiomyocyte diameter, LVW/BW, LVWT, LV protein and collagen content. However, sodium cromoglycate and ketotifen treatments significantly attenuated hyperhomocysteinemia-induced oxidative stress and pathological cardiac hypertrophy without significantly altering MABP. Moreover, sodium cromoglycate and ketotifen treatments did not affect serum homocysteine levels. CONCLUSIONS Thus, it may be concluded that hyperhomocysteinemia-induced cardiac hypertrophy is associated with an increase in oxidative stress and density of mast cells in heart. Sodium cromoglycate and ketotifen may have attenuated hyperhomocysteinemia-induced pathological cardiac hypertrophy, possibly by reducing oxidative stress and preventing the degranulation and increase in density of mast cells.

Abstract
Mast cells originate from pluripotent progenitor cells in bone marrow and are major players in the inflammation process. The involvements of mast cells in various cardiovascular complications such as arrhythmias, ischaemia reperfusion injury and graft rejection are well documented. Moreover, recent studies suggest the involvement of mast cells in cardiac hypertrophy and heart failure. The present review focuses on the role of mast cells in the development of cardiac hypertrophy and heart failure.

Abstract
The present study has been designed to investigate the effects of fenofibrate, a peroxisome proliferator-activated receptor (PPAR)alpha agonist, rosiglitazone, a PPARgamma agonist and the combination of both fenofibrate and rosiglitazone in partial abdominal aortic constriction (PAAC)-induced pathological cardiac hypertrophy in rats. Rats were subjected to PAAC for 4 weeks to produce pathological cardiac hypertrophy. The fenofibrate (3 mg/kg day(-1), p.o.), rosiglitazone (3 mg/kg day(-1), p.o.) and the combination of both fenofibrate (3 mg/kg day(-1), p.o.) and rosiglitazone (3 mg/kg day(-1), p.o.) were administered 3 days before PAAC and continued for 4 weeks after PAAC. The development of cardiac hypertrophy was assessed in terms of measuring ratio of left ventricular (LV) weight to body weight (LVW/BW), LV wall thickness (LVWT), LV protein content and LV collagen content. Further, the collagen accumulation in left ventricle was analyzed using picrosirius red staining. Moreover, the cross-sectional area (CSA) of cardiomyocytes was assessed using hematoxylin and eosin staining and measured using a NIH Scion image analyzer. The PAAC produced cardiac hypertrophy by increasing LVW/BW, LVWT, LV protein content, LV collagen content and mean CSA of cardiomyocytes. However, treatment with fenofibrate and rosiglitazone either alone or in combination significantly attenuated PAAC-induced increase in LVW/BW, LVWT, LV protein content, LV collagen content and mean CSA of cardiomyocytes. The combination of fenofibrate and rosiglitazone was more effective in attenuating the PAAC-induced cardiac hypertrophy than either drug alone. Thus, it may be concluded that dual activation of PPARalpha and PPARgamma may provide synergistic benefits in preventing the development of pathological cardiac hypertrophy.

Abstract
Peroxisome proliferator activated receptors (PPARs) are members of the nuclear hormone receptor superfamily of ligand-activated transcription factors. The PPAR subfamily consists of three members: PPARalpha, PPARgamma, and PPARbeta/delta. Fibrates are acting via PPARalpha, and they are used as lipid-lowering agents. PPARgamma agonists reduce insulin resistance and have been used in the treatment of type 2 diabetes. As the knowledge of the pleiotropic effects of these agents advances, further potential indications are being revealed, including a novel role in the management of cardiovascular disorders (CVD). PPARalpha/gamma dual agonists are currently under development and hold considerable promise in the management of type 2 diabetes and provide an effective therapeutic option for treating the multifactorial components of CVD. Several experimental and clinical evidences elucidated the beneficial effects of PPAR ligands in prevention and treatment of various CVD. However, PPARalpha and PPARgamma agonists have been shown to be proinflammatory and proatherogenic in a few studies. Further, PPARgamma ligands have been noted to be involved in the pathogenesis of congestive heart failure. These controversial results obtained from a few studies created further complication in understanding the role of PPARs. The function of PPARdelta and its potential as a cardiovascular therapeutic target are currently under investigation. The present review focuses on the merits and limitations of PPAR agonists with regard to their use in CVD.

Abstract
Heart failure, a complex disorder with heterogeneous aetiologies remains one of the most threatening diseases known. It is a clinical syndrome attributable to a multitude of factors that begins with the compensatory response known as hypertrophy, followed by a decompensated state that finally results in heart failure. Given the lack of a unified theory of heart failure, future research efforts are required to unify and synthesize our current understanding of the multiple mechanisms that control remodelling in heart under various stress conditions. During the past few decades, use of animal models has provided new insights into the complex pathogenesis of this syndrome. Rodents have contributed significantly in the understanding of the pathogenesis and progression of heart failure. With the advent of the transgenic era, rodent models have revolutionized preclinical research associated with heart failure. These models combined with physiological measurements of cardiac hemodynamics, are expected to yield more valuable information regarding the molecular mechanisms of heart failure and aid in the discovery of novel therapeutic targets. However, all animal models used have advantages and limitations, and the issues determining transfer from preclinical to clinical require critical evaluation. The present review focuses upon rodent models of heart failure.
