Abstract
Previous epidemiological and animal studies have showed the lipid metabolic disruption of antimicrobial triclocarban (TCC) and triclosan (TCS). However, the present in vivo researches were mainly devoted to the hepatic lipid metabolism, while the evidence about the impacts of TCC/TCS on the adipose tissue is very limited and the potential mechanism is unclear, especially the molecular initiation events. Moreover, little is known about the toxic difference between TCC and TCS. This study aimed to demonstrate the differential adipogenic activity of TCC/TCS as well as the potential molecular mechanism via peroxisome proliferator-activated receptors (PPARα/β/γ). The in vitro experiment based on 3T3-L1 cells showed that TCC/TCS promoted the differentiation of preadipocytes into mature adipocytes at nanomolar to micromolar concentrations, which was approach to their human exposure levels. We revealed for the first time by reporter gene assay that TCC could activate three PPARs signaling pathways in a concentration-dependent manner, while TCS only activate PPARβ. The molecular docking strategy was applied to simulate the interactions of TCC/TCS with PPARs, which explained well the different PPARs activities between TCC and TCS. TCC up-regulated the mRNA expression of three PPARs, but TCS only up-regulated PPARβ and PPARγ significantly. Meanwhile, TCC/TCS also promoted the expression of adipogenic genes targeted by PPARs to different extent. The cellular and simulating studies demonstrated that TCC exerted higher adipogenic effects and PPARs activities than TCS. Our mice in vivo experiment showed that TCC could lead to adipocyte size increase, adipocyte lipid accumulation growing, fat weight and body weight gain at human-related exposure levels, and high fat diet exacerbated these effects. Moreover, male mice tended to be more susceptible to TCC induced obesogenic effect than female mice. This work highlights the potential obesogenic risks of TCC/TCS via PPARs signaling pathways, and TCC deserves more concerns for its higher activity.

Abstract
Purpose Puerarin is the main isoflavone extracted from Radix Puerariae lobata (Willd.) and exerts a strong protective effect on endothelial cells. This isoflavone also exerts proven angiogenic effects; however, the potential underlying mechanism has not been fully explored. Here in this work, we aimed to determine the proangiogenesis effect of a puerarin-attached lignin nanoparticle-incorporated hydrogel and explore the underlying mechanism. Materials and Methods Puerarin-attached lignin nanoparticles were fabricated and mixed with the GelMA hydrogel. After the hydrogel was characterized, the angiogenic effect was evaluated in a mouse hind-limb ischemia model. To further explore the mechanism of angiogenesis, human endothelial cell line EA.hy926 was exposure to different concentrations of puerarin. Wound healing assays and tube formation assays were used to investigate the effects of puerarin on cell migration and angiogenesis. qPCR and Western blotting were performed to determine the changes in the levels of angiogenesis indicators, autophagy indicators and PPARβ/δ. 3-MA was used to assess the role of autophagy in the puerarin-mediated angiogenesis effect in vivo and in vitro. Results The hydrogel significantly improved blood flow restoration in mice with hind-limb ischemia. This effect was mainly due to puerarin-mediated increases in the angiogenic capacity of endothelial cells and the promotion of autophagy activation. A potential underlying mechanism might be that puerarin-mediated activation of autophagy could induce an increase in PPARβ/δ expression. Conclusion The puerarin-attached lignin nanoparticle-incorporated hydrogel effectively alleviated blood perfusion in mice with hind-limb ischemia. Puerarin has a prominent proangiogenic effect. The potential mechanisms might be that puerarin-mediated autophagy activation and increase in PPARβ/δ.

Abstract
Osteoarthritis (OA) represents the foremost degenerative joint disease observed in a clinical context. The escalating issue of population aging significantly exacerbates the prevalence of OA, thereby imposing an immense annual economic burden on societies worldwide. The current therapeutic landscape falls short in offering reliable pharmaceutical interventions and efficient treatment methodologies to tackle this growing problem. However, the scientific community continues to dedicate significant efforts towards advancing OA treatment research. Contemporary studies have discovered that the progression of OA may be slowed through the strategic influence on peroxisome proliferator-activated receptors (PPARs). PPARs are ligand-activated receptors within the nuclear hormone receptor family. The three distinctive subtypes-PPARα, PPARβ/δ, and PPARγ-find expression across a broad range of cellular terminals, thus managing a multitude of intracellular metabolic operations. The activation of PPARγ and PPARα has been shown to efficaciously modulate the NF-κB signaling pathway, AP-1, and other oxidative stress-responsive signaling conduits, leading to the inhibition of inflammatory responses. Furthermore, the activation of PPARγ and PPARα may confer protection to chondrocytes by exerting control over its autophagic behavior. In summation, both PPARγ and PPARα have emerged as promising potential targets for the development of effective OA treatments.

Abstract
As the primary molecular target, there is still a gap between the peroxisome proliferator-activated receptors (PPARs) regulation and the adverse health effects caused by per- and polyfluoroalkyl substances (PFASs). The effects of PFASs on cellular differentiation regulated by PPARs is likely significant given the association of PFASs exposure with obesity and decreased bone density. Human mesenchymal stem cells (hMSCs) were used as an in vitro model to assess the roles of PPAR subtypes in the multipotent differentiation of hMSCs affected by perfluorooctanesulfonate (PFOS), perfluorooctanoic acid (PFOA) and their replacement compounds. PFASs increased the expression of three PPAR subtypes in proliferating and differentiating hMSCs. Meanwhile, PFOS and PFOA decreased osteogenesis, enhanced adipogenesis, and increased bone turnover in hMSCs. Similarly, PFOA alternatives, hexafluoropropylene oxide dimer acid (HFPO-DA) and hexafluoropropylene oxide trimer acid (HFPO-TA), exhibited similar or even higher potency in affecting stem cell differentiation compared with PFOA. Perfluorohexanesulfonate (PFHxS) inhibited osteogenesis with comparable potency to PFOS. In contrast, 6:2 chlorinated poly-fluoroalkyl ether sulfonate (6:2Cl-PFESA) enhanced osteogenesis. PPARβ expression is significantly positively correlated with osteogenesis and osteoprotegerin (OPG) secretion in 6:2Cl-PFESA treated cells. shRNA knockdown of PPARβ remarkably reversed the osteogenic effects of 6:2Cl-PFESA and enhanced the adipogenic effects of the six chemicals. The results suggested that the adverse effects and relative potency of PFASs on the multipotent differentiation of hMSCs were dependent on the integrated action of the three PPAR subtypes, which facilitates a better understanding of the molecular initiating events of PFASs. The present study may well explain the mechanism of the decreased bone density and increased obesity incidence among those exposed to legacy PFASs, and indicates the necessity of further health risk assessment for the alternatives.

Abstract
Prostaglandins (PGs) are highly reactive small lipophilic molecules derived from polyunsaturated fatty acids of the cell membrane and play a key role in the resolution of inflammation processes. 15-deoxy-Δ12,14-PGJ2 (15dPGJ2) is a cyclopentenone PG (CyPG) of the J series with anti-inflammatory, anti-proliferative and pro-apoptotic effects. This CyPG can signal through: (i) the PGD2 receptor (DP2) and peroxisome proliferator-activated receptor γ (PPARγ) or (ii) by covalent binding to protein nucleophiles, such as, thiols groups of cysteine, lysine or histidine via a Michael addition reaction, modifying its structure and function. In this work we show that acidophilic granulocytes (AGs) of gilthead seabream (Sparus aurata L.), the functional equivalent to mammalian neutrophils, constitutively expressed ppara, pparb and pparg genes, the latter showing the highest expression and up-regulation when stimulated by bacterial DNA. In addition, we tested the ability of 15dPGJ2, and its biotinylated analog, as well as several PPARγ ligands, to modulate reactive oxygen species (ROS) and/or cytokines production during a Toll like receptor (TLR)-mediated granulocyte response. Thus, 15dPGJ2 was able to significantly decrease bacterial DNA-induced ROS production and transcript levels of pparg, interleukin-1β (il1b) and prostaglandin-endoperoxide synthase 2 (ptgs2). In contrast, its biotinylated analog was less potent and a higher dose was required to elicit the same effects on ROS production and cytokine expression. In addition, different PPARγ agonists were able to mimic the effects of 15dPGJ2. Conversely, the PPARγ antagonist T007097 abolished the effect of 15dPGJ2 on DNA bacterial-induced ROS production. Surprisingly, transactivation assays revealed that both 15dPGJ2 and its biotinylated analog signaled via Pparα and Pparβ, but not by Pparγ. These results were further confirmed by HPLC/MS analysis, where Pparβ was identified as an interactor of biotin-15dPGJ2 in naïve and DNA-stimulated leukocytes. Taken together, our data show that 15dPGJ2 acts both through Ppar activation and covalent binding to proteins in fish granulocytes and identify for the first time in vertebrates a role for Pparα and Pparβ in the resolution of inflammation mediated by 15dPGJ2.

Abstract
Peroxisome proliferator-activated receptors (PPARs) function as nuclear transcription factors upon the binding of physiological or pharmacological ligands and heterodimerization with retinoic X receptors. Physiological ligands include fatty acids and fatty-acid-derived compounds with low specificity for the different PPAR subtypes (alpha, beta/delta, and gamma). For each of the PPAR subtypes, specific pharmacological agonists and antagonists, as well as pan-agonists, are available. In agreement with their natural ligands, PPARs are mainly focused on as targets for the treatment of metabolic syndrome and its associated complications. Nevertheless, many publications are available that implicate PPARs in malignancies. In several instances, they are controversial for very similar models. Thus, to better predict the potential use of PPAR modulators for personalized medicine in therapies against malignancies, it seems necessary and timely to review the three PPARs in relation to the didactic concept of cancer hallmark capabilities. We previously described the functions of PPAR beta/delta with respect to the cancer hallmarks and reviewed the implications of all PPARs in angiogenesis. Thus, the current review updates our knowledge on PPAR beta and the hallmarks of cancer and extends the concept to PPAR alpha and PPAR gamma.
