Abstract
One of the main causes of death on the globe is cancer. Peroxisome-proliferator-activated receptors (PPARs) are nuclear hormone receptors, including PPARα, PPARδ and PPARγ, which are important in regulating cancer cell proliferation, survival, apoptosis, and tumor growth. Activation of PPARs by endogenous or synthetic compounds regulates tumor progression in various tissues. Although each PPAR isotype suppresses or promotes tumor development depending on the specific tissues or ligands, the mechanism is still unclear. PPARs are receiving interest as possible therapeutic targets for a number of disorders. Numerous clinical studies are being conducted on PPARs as possible therapeutic targets for cancer. Therefore, this review will focus on the existing and future uses of PPARs agonists and antagonists in treating malignancies. PubMed, Science Direct, and Scopus databases were searched regarding the effect of PPARs on various types of cancers until the end of May 2023. The results of the review articles showed the therapeutic influence of PPARs on a wide range of cancer on in vitro, in vivo and clinical studies. However, further experimental and clinical studies are needed to be conducted on the influence of PPARs on various cancers.

Abstract
Endometriosis is one of the major gynecological diseases of reproductive-age women. This disease is characterized by the presence of glands and stroma outside the uterine cavity. Several studies have shown the major role of inflammation, angiogenesis, adhesion and invasion, and apoptosis in endometriotic lesions. Nevertheless, the mechanisms underlying endometriotic mechanisms still remain unclear and therapies are not currently efficient. The introduction of new agents can be effective by improving the condition of patients. PPARγ ligands can directly modulate these pathways in endometriosis. However, data in humans remain low. Thus, the purpose of this review is to summarize the potential actions of PPARγ agonists in endometriosis by acting on inflammation, angiogenesis, invasion, adhesion, and apoptosis.

Abstract
Peroxisome proliferator-activated receptor γ (PPARγ), one of the transcription factors that regulate lipid metabolism and energy use in tumor cells, is a viable target for cancer therapy. In our search for potential PPARγ activator, extracts from five Formosan plants were tested. Among them, Momordica charantia L. showed the highest ability to activate PPARγ, which led us to identify its potential constituents. Among the seven compounds isolated from M. charantia, a triterpenoid, 5β,19-epoxy-19-methoxycucurbita-6,23-dien-3β,25-diol (compound 1), was identified as a PPARγ activator with an IC50 of 10 μM in breast cancer MCF-7 cells. Flow cytometric analysis indicated that compound 1 induced G1 cell cycle arrest which might be attributable to the modulation of phosphorylation and expression of numerous key signaling effectors, including cyclin D1, CDK6, and p53. Notably, compound 1 downregulated the expression of histone deacetylase 1, leading to increased histone H3 acetylation. Taken together, these findings suggest that compound 1 may have therapeutic applications in cancer treatment through PPARγ activation. Copyright © 2017 John Wiley & Sons, Ltd.

Abstract
This study was designed to evaluate the effect of beta-sitosterol (BS) on the peroxisome proliferator-activated receptor gamma (PPAR-γ) gene expression role in the activity of paraoxonase (PON-1) enzyme in oxidative stress status of irradiated rats. Animals were exposed to whole body γ-radiation single dose 6 Gy and received BS dose (40 mg·(kg body mass)-1·day -1, orally). In liver tissue, gene expression of PPAR-γ ligand was determined. Oxidative stress marker (malondialdehyde, MDA) and antioxidant enzyme activities (superoxide dismutase (SOD), catalase (CAT), PON-1, and arylesterase (ARE)) were assayed in serum and liver tissue. Also, serum lipid profile (cholesterol, triglycerides (TG), low-density lipoprotein cholesterol (LDL-c), and high-density lipoprotein cholesterol (HDL-c)) was measured. In irradiated animals that received BS, expression of PPAR-γ ligand increase significantly associated with increase in PON-1 and ARE enzyme activities. Also, the activities of SOD, CAT enzymes, and HDL-c levels display elevation. By contrast, significant decrease in MDA content, cholesterol, TG, and LDL-c levels were revealed after BS administration. Our findings in this study provide the evidence that BS has radio-protective effect via regulating the gene expression of PPAR-γ, causing an increase in PON-1 and ARE enzyme activities. This action of BS is due to its free radical scavenging properties, antioxidant effect, lowering of cholesterol, and PPAR-γ agonist properties.

Pioglitazone induces cell growth arrest and activates mitochondrial apoptosis in human uterine leiomyosarcoma cells by a peroxisome proliferator-activated receptor γ-independent mechanism. Naunyn Schmiedebergs Arch Pharmacol 2016; 390:37-48.

Abstract
The peroxisome proliferator-activated receptor γ (PPARγ) agonists, thiazolidinediones, including pioglitazone (PIO) exhibit anti-tumour activities in cancer cells. The present study investigates the effects of PIO on cell proliferation and apoptosis in SK-UT-1 cells, a human uterine leiomyosarcoma cell line, and human uterine smooth muscle cells (HUtSMC). The proliferation and viability of SK-UT-1 cells treated with vehicle or PIO were assessed by cell counting and WST-1 assay. The activity of MEK/ERK and p38 MAPK signalling pathways and the expression of p53, the cyclin-dependent kinase inhibitor, p21, Bax, Bad and Bim proteins and cleaved caspase-3 were analysed by Western blotting. Quiescent SK-UT-1 cells intensively proliferate and display high levels of phosphorylated, activated MEK1/2, ERK1/2 and p38 MAPK. PIO (10 or 25 μM) induced time- and dose-dependently cell-growth arrest, reduced the cell numbers and effectively suppressed the over-activated MEK/ERK and p38 MAPK signalling pathways as evidenced by the abolished levels of phosphorylated MEK1/2, ERK1/2 and p38 MAPK. PIO activated the intrinsic apoptotic pathway, i.e. up-regulated the p53, p21, Bax and Bad proteins and cleaved caspase-3. PIO also reduced cell numbers of highly proliferative SK-UT-1 cells cultured in growth medium. The anti-proliferative and pro-apoptotic actions of PIO were not PPARγ dependent and exclusive for SK-UT-1 cells as PIO did not interfere with the proliferation of HUtSMC. The pronounced anti-tumorigenic effects of PIO in SK-UT-1 cells address an important issue about the relevance of the PPARγ agonist in the treatment of the human uterine leiomyosarcoma.

The Inflammation Response to DEHP through PPARγ in Endometrial Cells. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2016; 13:ijerph13030318.

Abstract
Epidemiological studies have shown the possible link between phthalates and endometrium-related gynecological diseases, however the molecular mechanism(s) behind this is/are still unclear. In the study, both primary cultured endometrial cells and an endometrial adenocarcinoma cell line (Ishikawa) were recruited to investigate the effects of di-(2-ethylhexyl) phthalate (DEHP) at human-relevant concentrations. The results showed that DEHP did not affect the viability of either type of cell, which showed different responses to inflammation. Primary cultured cells showed stronger inflammatory reactions than the Ishikawa cell line. The expression of inflammatory factors was induced both at the mRNA and protein levels, however the inflammation did not induce the progress of epithelial-mesenchymal transition (EMT) as the protein levels of EMT markers were not affected after exposure to either cell type. Further study showed that the mRNA levels of peroxisome proliferator-activated receptor gamma (PPARγ) wereup-regulated after exposure. In all, our study showed that human-relevant concentrations of DEHP could elicit the inflammatory response in primary cultured endometrial cells rather than in Ishikawa cell line. PPARγ may act as the mediating receptor in the inflammation reaction.

Abstract
Apoptosis is an important process in the reconstruction of endometrium within the menstrual cycle. The balance between cell proliferation and apoptosis regulates the periodic repair and shedding of endometrial cells and leads to the menstruation or prepare the mucosal layer of endometrium for the implantation of the embryo. Many factors with pro- and antiapoptotic action, such as B cell lymphoma/leukemia-2 and inhibitors apoptosis proteins families, caspases, tumor necrosis factor receptors, phosphatase and tensin homolog, proliferator-activated receptor gamma, microRNAs and others are differently expressed in the endometrial tissue at phases of menstrual cycle. Receptivity of the endometrium at the period of “window of implantation” is associated with the significant increase of apoptosis in endometrium to allow the embryo to be successfully implanted. The impairment of apoptosis regulation in the endometrium at this period often is observed in infertile women with endometriosis, tubal factor, polycystic ovary syndrome, etc.. In many cases the impairment of apoptosis regulation in the endometrium is the main cause of in vitro fertilization (IVF) treatment failure in these patients. As of today, the exact mechanisms and factors mediating the apoptotic process in normal endometrium and in infertile women are not fully understood. Herein, the literature data concerning the endometrial apoptosis regulation in general, and in light of the influence of apoptosis upon IVF treatment outcome are reviewed. The possibility to use some parameters of endometrial apoptosis for prediction of the successful pregnancy achievement in women participating in IVF protocols also is discussed.
