Protocol

Cell Assay [2]
Human umbilical vein ECs (HUVECs) are cultured in EGM-2. Subconfluent HUVECs are made quiescent by serum starvation [EBM-2 containing 0.1% fetal bovine serum (FBS)] for 4 h. The cells are pretreated with the PPARδ ligand L-165041 or GW501516 for 6 h followed by VEGF (10 ng/mL) induction [2].

Animal Administration [3]
LDLR−/− mice are divided into vehicle (0.1 N NaOH) and L-165041 (5 mg/kg/day) group (9 animals in each group). LDLR−/− mice receive either NaOH or L-165041 via daily intraperitoneal injection (i.p.) for 16 weeks with the Western diet. Body weight is measured once a week and the blood samples for a serum parameter analysis are collected using an eye-bleeding method every 4 weeks. At the end of the experiment, LDLR−/− mice are fasted for 24 h before sacrificed and the liver samples are either fixed in formalin or frozen at −70°C for further analysis. All animals are housed in polycarbonate cages in a room with a 12-h light/12-h dark cycle, and maintained at a constant temperature of 22°C[3].

Background on L-165041

Ki: 6 nM for PPARγ

Peroxisome proliferator-activated receptor (PPARγ) is known to be expressed ubiquitously and involved in lipid and glucose metabolism. Studies have demonstrated that PPARγ is expressed in endothelial cells and plays a potential role in endothelial proliferation and survival. L-165041 is reported as a selective and potent PPARγ ligand.

In vitro: L-165041, which is a selective and potent PPARδligand, displayed in this specified transactivation system, apart from its highly efficacious PPARδ agonist activity, partial and full agonism at, respectively, PPARγ2 and PPARαsubtypes [1].

In vivo: L-165041 could drastically reduce lipid accumulation in the mouse liver, decreasing total hepatic triglyceride and cholesterol content compared to the vehicle group. Gene analysis demonstrated that L-165041 lowered hepatic expression of PPARγ, apolipoprotein B, IL-1β, and interleukin-6. In contrast, L-165041 increased hepatic expressions of PPARδ, lipoprotein lipase, and ATP-binding cassette transporter G1 (ABCG1) [2].

Clinical trial: Up to now, L-165041 is still in the preclinical development stage.

PPAR delta agonist L-165041 inhibits rat vascular smooth muscle cell proliferation and migration via inhibition of cell cycle.[Pubmed:18585719]

Atherosclerosis. 2009 Feb;202(2):446-54.

The peroxisome proliferator-activated receptor (PPAR) family of nuclear hormone receptors consists of three subtypes (alpha, beta/delta, and gamma). PPAR delta is ubiquitously expressed and involved in lipid and glucose metabolism. However, the effect of PPAR delta on vascular smooth muscle cell (VSMC) proliferation and migration has not been fully elucidated yet. Here, we investigated the effect of L-165041, a selective ligand for PPAR delta, on PDGF-induced rat VSMC proliferation. Our data show that L-165041 inhibited rat VSMC proliferation in a dose dependent manner by blocking G(1) to S phase progression and repressing the phosphorylation of retinoblastoma protein (Rb). Furthermore, L-165041 inhibited PDGF-induced expression of cyclin D1 and CDK4. These effects less likely involve PPAR gamma pathway because PPAR gamma antagonist GW9662 pretreatment failed to reverse the inhibitory effect of L-165041 on rVSMC proliferation and migration. For in vivo studies, L-165041 was administered to Sprague-Dawley rats using osmotic pumps before and after the carotid balloon injury, and L-165041 decreased neointima formation after the carotid injury. In conclusion, our results suggest that PPAR delta ligand L-165041 can be a therapeutic agent to control pathologic cardiovascular conditions such as restenosis and atherosclerosis.

The PPARbeta agonist L-165041 promotes VEGF mRNA stabilization in HPV18-harboring HeLa cells through a receptor-independent mechanism.[Pubmed:24172859]

Cell Signal. 2014 Feb;26(2):433-43.

Peroxisome Proliferator-Activated Receptor-beta (PPARbeta) is a ligand-inducible transcription factor activated by both natural (fatty acids and derivatives) and high affinity synthetic agonists. It is thought to play a role in angiogenesis development and Vascular Endothelial Growth Factor (VEGF) regulation but its contribution remains unclear. Until now, the PPARbeta agonism effect on VEGF expression in cervical cancer cells was unknown. This led to our interest in assessing the effect of PPARbeta activation on the regulation of different VEGF isoforms mRNA expression and the impact of E6 viral oncoprotein and its target p53 on this regulation in cervical cancer cells. Here, we showed that the PPARbeta agonist L-165041 induces VEGF(121), VEGF(165) and VEGF(189) expression in HPV (Human Papillomavirus) positive HeLa cells but not in HPV negative cells. The underlying mechanisms did involve neither E6 oncoprotein nor p53. We highlighted a novel mode of PPARbeta ligand action including a post-transcriptional regulation of VEGF mRNA expression through the p38 MAPK signaling pathway and the activation of the mRNA-stabilizing factor HuR. But most importantly, we clearly demonstrated that L-165041 acts independently of PPARbeta since its effect was not reversed by a chemical inhibition with a specific antagonist and the siRNA-mediated knockdown of the nuclear receptor. As VEGF is crucial for cancer development, the impact of PPARbeta ligands on VEGF production is of high importance. Thus, the molecular mechanism of their action has to be elucidated and as a result, PPARbeta agonists currently in clinical trials should be carefully monitored.

PPARdelta ligand L-165041 ameliorates Western diet-induced hepatic lipid accumulation and inflammation in LDLR-/- mice.[Pubmed:19766624]

Eur J Pharmacol. 2009 Nov 10;622(1-3):45-51.

Although peroxisome proliferator-activated receptor delta (PPARdelta) has been implicated in energy metabolism and lipid oxidation process, detailed roles of PPARdelta in lipid homeostasis under pathologic conditions still remain controversial. Thus, we investigated the effect of PPARdelta ligand L-165041 on Western diet-induced fatty liver using low-density lipoprotein receptor-deficient (LDLR(-/-)) mice. LDLR(-/-) mice received either L-165041 (5mg/kg/day) or vehicle (0.1N NaOH) with Western diet for 16 weeks. According to our data, L-165041 drastically reduced lipid accumulation in the liver, decreasing total hepatic cholesterol and triglyceride content compared to the vehicle group. Gene expression analysis demonstrated that L-165041 lowered hepatic expression of PPARgamma, apolipoprotein B, interleukin 1 beta (IL-1beta), and interleukin-6. In contrast, L-165041 increased hepatic expressions of PPARdelta, lipoprotein lipase (LPL), and ATP-binding cassette transporter G1 (ABCG1). Our data suggest that L-165041 might be effective in preventing Western diet-induced hepatic steatosis by regulating genes involved in lipid metabolism and the inflammatory response.

The PPARdelta ligand L-165041 inhibits VEGF-induced angiogenesis, but the antiangiogenic effect is not related to PPARdelta.[Pubmed:22234939]

J Cell Biochem. 2012 Jun;113(6):1947-54.

Peroxisome proliferator-activated receptor (PPAR)delta is known to be expressed ubiquitously and involved in lipid and glucose metabolism. Recent studies have demonstrated that PPARdelta is expressed in endothelial cells (ECs) and plays a potential role in endothelial survival and proliferation. Although PPARalpha and PPARgamma are well recognized to play anti-inflammatory, antiproliferative, and antiangiogenic roles in ECs, the general effect of PPARdelta on angiogenesis in ECs remains unclear. Thus, we investigated the effect of the PPARdelta ligand L-165041 on vascular EC proliferation and angiogenesis in vitro as well as in vivo. Our data show that L-165041 inhibited VEGF-induced cell proliferation and migration in human umbilical vein ECs (HUVECs). L-165041 also inhibited angiogenesis in the Matrigel plug assay and aortic ring assay. Flow cytometric analysis indicated that L-165041 reduced the number of ECs in the S phase and the expression levels of cell cycle regulatory proteins such as cyclin A, cyclin E, CDK2, and CDK4; phosphorylation of the retinoblastoma protein was suppressed by pretreatment with L-165041. We confirmed whether these antiangiogenic effects of L-165041 were PPARdelta-dependent using GW501516 and PPARdelta siRNA. GW501516 treatment did not inhibit VEGF-induced angiogenesis, and transfection of PPARdelta siRNA did not reverse this antiangiogenic effect of L-165041, suggesting that the antiangiogenic effect of L-165041 on ECs is PPARdelta-independent. Together, these data indicate that the PPARdelta ligand L-165041 inhibits VEGF-stimulated angiogenesis by suppressing the cell cycle progression independently of PPARdelta. This study highlights the therapeutic potential of L-165041 in the treatment of many disorders related to pathological angiogenesis.
