Summary: Naringenin, an activator found in citrus fruits, has beneficial effects on thermogenesis and insulin sensitivity. Our study investigated if carotenoids can enhance the metabolic effects of naringenin on adipocytes. Results showed that beta-carotene acts synergistically with naringenin to improve thermogenesis and glucose metabolism genes.

Summary: Atherosclerosis, a major factor of cardiovascular disease, is influenced by inflammation, dyslipidemia, and oxidative stress. Peroxisome proliferator-activated receptors (PPARs), as nuclear receptors, have tissue- and cell-specific expression and regulate genes involved in lipid metabolism, inflammation, and redox homeostasis. Despite controversies, accumulating evidence supports the role of PPAR activation in attenuating atherosclerosis. Recent advances provide valuable insights into the mechanisms of PPAR activation.

Summary: Obesity leads to chronic low-grade inflammation, causing diabetes, steatosis, and insulin resistance. Activation of the p38 pathway in macrophages plays a crucial role in this inflammation, suggesting p38 inhibition as a potential treatment for obesity comorbidities. However, lack of p38 activation in myeloid cells worsens high-fat diet-induced obesity, diabetes, and steatosis. Deficient p38 activation increases macrophage IL-12 production, leading to inhibition of hepatic FGF21 and reduction of thermogenesis in the brown fat.

Summary: In this study, the structural and energetic mechanism of RXRα-PPARγ heterodimer in bound or unbound state to DNA and in complex with co-crystallized ligands was explored through simulations and analysis. The results suggest that DNA binding alters the correlated motions and conformational mobility within the system, affecting the dimerization and binding affinity of RXRα-PPARγ complex. Additionally, PPARγ plays a greater role in regulating the free and bound DNA state.

Summary: Activation of systemic, renal vessel and renal tissue levels of PPAR gamma by chronic pioglitazone treatment has beneficial effects on endotoxemia-related TNF alpha/NF kappa B-mediated acute and chronic renal inflammation in cirrhosis. This study revealed that normalization of renal and renal arterial levels of PPAR gamma effectively prevented LPS-induced acute and chronic renal dysfunction in cirrhotic ascitic rats.

Summary: This study found that the expression levels of IL-17 were significantly increased in pregnant women with preeclampsia (PE), and IL-17 may serve as a sensitive biomarker for PE. Overexpression of IL-17 promoted the viability, migration, and invasion of trophoblast cells, while knockdown of IL-17 inhibited these effects. Furthermore, IL-17 activated the PPAR-gamma/RXR-alpha/Wnt signaling pathway to promote proliferation, migration, and invasion of trophoblast cells.

Summary: There is a close relationship between intestinal inflammation and nutrition in patients with inflammatory bowel disease (IBD). Patients with active IBD have poor nutritional status, reduced levels of short-chain fatty acids, and altered expression of tight junction proteins in the intestine.

Summary: Cardiotoxicity can be a complication caused by drugs and chemicals, affecting morbidity, quality of life, and mortality. The role of peroxisome proliferator-activated receptors (PPARs) in controlling gene expression related to lipid metabolism and inflammation in the heart has been identified. Natural chemicals can protect against cardiotoxicity by targeting PPARs.

Summary: The study demonstrates that targeting the PPAR gamma/RXR alpha heterodimer with pioglitazone and bexarotene is effective in reducing cell proliferation in head and neck squamous cell carcinoma. There is potential for clinical application, but further research is needed to fully explore the chemopreventive potential of these medications.

Summary: Bexarotene, a selective RXR agonist, has shown protective effects against hyperalgesia induced by LPS in a mouse model of inflammatory pain. It is possible that these effects are mediated by decreased activity of the TLR4/MyD88/TAK1/NF-kappa B/COX-2 signaling pathway in the central nervous system, as well as increased formation of pro-inflammatory cytokines.

Summary: The review evaluates the potential of using CRP as a biomarker for psychiatric disorders, based on accumulating evidence from large studies and meta-analyses. CRP may serve as a 'psychiatric biomarker' to inform clinicians about neuroinflammation, medication effects, cardiometabolic status, comorbidities, and potentially guide treatment selection based on clinical outcomes.

Summary: The present study aimed to explore the contribution of mammalian target of rapamycin (mTOR) in DOCA salt-induced hypertension and related pathophysiological changes in cardiovascular and renal tissues. The results showed that mTOR played an important role in regulating blood pressure and the development of cardiovascular and renal pathophysiological changes. Pharmacological inhibition of mTOR could serve as a novel target for the treatment of hypertension.
