background: peroxisome proliferative-activated receptors (ppars) are nuclear receptors that involved in cellular lipid metabolism and differentiation. the subtype ? of the ppar family (ppar?) plays important roles in physiologic functions of ovaries. objective: to determine correlation between ppar? protein level in granulosa cells and pregnancy rate in women undergoing in-vitro fertilization (...
Peroxisome proliferators cause liver cell proliferation in addition to other pleiotropic effects such as peroxisome proliferation and induction of certain peroxisomal and cytosolic enzymes in liver. Since dexamethasone has been shown to inhibit mitogen-induced liver cell hyperplasia, we examined whether dexamethasone inhibits only cell proliferation without affecting peroxisome proliferation in...
To determine whether or not the expression of mevalonate pyrophosphate decarboxylase (MPD) depends on the proliferation of peroxisomes, we examined change in the protein level of MPD in the crude extract, the cytosol and the peroxisome-enriched fraction of the livers of rats administered peroxisome proliferative drugs. No increase of MPD was observed in any of these fractions. These data sugges...
Trichloroethylene (TCE) and related hydrocarbons constitute an important class of environmental pollutants whose adverse effects on liver, kidney, and other tissues may, in part, be mediated by peroxisome proliferator-activated receptors (PPARs), ligand-activated transcription factors belonging to the steroid receptor superfamily. Activation of PPAR induces a dramatic proliferation of peroxisom...
objective(s): t-cell acute lymphoblastic leukemia (t-all) is an aggressive hematologic malignant tumor. administration of chemical compounds influencing apoptosis and t cell development has been discussed as promising novel therapeutic strategies. valproic acid (vpa) as a recently emerged anti-neoplastic histone deacetylase (hdac) inhibitor and pioglitazone (pgz) as a high-affinity peroxisome p...

The epithelial‑mesenchymal transition (EMT) of retinal pigment epithelial (RPE) cells is an important underlying mechanism proliferative vitreoretinopathy (PVR). We previously found that L‑carnitine (β‑hydroxy‑γ‑N-trimethylammonium‑butyrate, LC) was significantly lower during the transforming growth factor‑β1 (TGF‑β1)‑induced EMT process in ARPE‑19 cells. present study assessed role LC RPE migr...
Dehydroepiandrosterone, a major secretory steroid hormone of the human adrenal gland, possesses mitoinhibitory and anticarcinogenic properties. It also induces peroxisome proliferation in the livers of rats and mice. Because peroxisome proliferators exhibit hepatocarcinogenic potential, it is necessary to examine the long term hepatic effects of dehydroepiandrosterone since this hormone is cont...
Progenitor/stem cell populations of epithelium are known to reside in the small-sized cell population. Our objective was to physically isolate and characterize an oral keratinocyte-enriched population of small-sized progenitor/stem cells. Primary human oral mucosal keratinocytes cultured in a chemically defined serum-free culture system, devoid of animal-derived feeder cells, were sorted by rel...
