Summary: Osteoarthritis (OA) is a common degenerative joint disease that is exacerbated by population aging, resulting in a significant economic burden. Current therapies are inadequate, but research on peroxisome proliferator-activated receptors (PPARs) shows promise in slowing OA progression. PPARs have emerged as potential targets for effective OA treatments.

Summary: PPARs play vital roles in pregnancy, and dysfunctions of PPARs may lead to various related pregnancy diseases such as recurrent miscarriage and preeclampsia. This review discusses the impact of regulating PPARs on trophoblast physiological conditions and explores the underlying mechanisms of PPARs in controlling pregnancy-related processes.

Summary: PPARs, belonging to the nuclear hormone receptor superfamily, play important roles in regulating lipid and carbohydrate metabolisms, as well as various cell functions and physiological processes. Their ability to modulate antioxidant genes expression and inhibit pro-inflammatory mediators synthesis makes them key regulators in cellular response against oxidative stress.

Summary: Inherited metabolic disorders (IMDs) are genetic disorders that disrupt specific metabolic pathways, leading to biochemical, clinical, and pathophysiological consequences. Secondary mitochondrial dysfunction, particularly oxidative phosphorylation impairment and elevated reactive oxygen species, has been found to play a crucial role in many of these disorders. Peroxisomal proliferator-activated receptors (PPARs), a group of nuclear hormone receptors, regulate various cellular functions and processes, including oxidative stress response, inflammation, lipid metabolism, and mitochondrial bioenergetics. Activation of PPARs has shown to improve oxidative phosphorylation and reduce reactive species levels, making pharmacological treatment with PPAR activators a promising approach for IMDs. This review summarizes preclinical and clinical data on the effects of PPARs in IMDs.

Summary: This review focuses on the mechanisms by which nuclear receptors mediate transcriptional responses, with a specific emphasis on the role of PPARγ in regulating blood pressure. Genetic and clinical trial data demonstrate the importance of PPARγ in hypertension, and the tissue- and cell-specific molecular mechanisms by which PPARs modulate blood pressure and related phenotypes are detailed. The role of placental PPARs in preeclampsia is also discussed, along with future research directions and implications for novel therapies.

Summary: This study investigated the role of platelet IKCa channels in platelet function and NO generation. The results showed that activation of IKCa channels can inhibit platelet aggregation by reducing calcium signaling and granule secretion. This finding provides a new target for the development of antiplatelet drugs that limit atherothrombosis.

Summary: This study summarizes the physiological importance and clinical significance of PPARs and reviews the experimental evidence that natural products mediate metabolic syndrome via PPARs. The majority of currently described natural compounds are mild PPAR-selective agonists with therapeutic effects that are equivalent to synthetic medicines but less harmful adverse effects. Conclusion: PPAR agonists can be combined with natural products to treat and prevent metabolic syndrome.

Summary: NBIF is identified as a potent natural inducer of UGT1A1, mainly activating and up-regulating PPAR alpha and PPAR gamma to induce UGT1A1 expression. This finding suggests that NBIF could be a promising lead compound for the development of more efficacious UGT1A1 inducers to treat hyperbilirubinaemia and UGT1A1-associated drug toxicities.

Summary: Endometrial carcinoma is the most common malignant tumor of the female genital tract in the United States. Peroxisome proliferator-activated receptors (PPARs) are nuclear receptor proteins which regulate gene expression. In our literature review of 27 relevant studies published between 2000 and 2023, it was found that PPAR alpha and PPAR beta/delta isoforms were upregulated in endometrial cancer cells, while PPAR gamma levels were significantly lower. Interestingly, PPAR agonists were found to be potent anti-cancer therapeutic alternatives. Overall, PPARs seem to play a significant role in endometrial cancer.

Summary: Preeclampsia is a common hypertensive disorder in pregnancy, and PPARs play a significant role in its pathophysiology. Studies have shown contradictory conclusions regarding PPAR expression in preeclamptic placentae, but PPAR gamma agonists have been identified as a novel and potent anti-preeclamptic treatment option.

Summary: This study investigates the effects of Aβ(1-42) toxicity on the maturation of astrocyte/oligodendrocyte co-cultured precursor cells and the potential beneficial effects of the anti-inflammatory and neuroprotective compound co-ultra PEALut. The results show that Aβ(1-42) induces astrocyte reactivity and inflammation, leading to reduced levels of growth factors important for OPCs maturation. Co-ultra PEALut counteracts these negative effects and preserves the morphology of co-cultured oligodendrocytes through mechanisms involving PPAR-α.

Summary: The nuclear liver X receptors (LXRα/β) and peroxisome proliferator-activated receptors (PPARα/γ) play a role in regulating lipid metabolism and inflammation. The activation of these receptors has neuroprotective effects and may be a potential treatment for neurodegenerative disorders like Alzheimer's Disease (AD). The brown seaweed Sargassum fusiforme contains compounds that activate these receptors and have been shown to prevent disease progression in a mouse model of AD.

Summary: The levels of endogenous PPAR gamma ligands PGJ2 and 15(S)-HETE are significantly decreased in PTC. Inhibition of ER alpha or activation of ER beta can inhibit PTC by stimulating the production of endogenous PPAR gamma ligands to induce apoptosis in cancer cells.
