Imatinib is actively transported by organic cation transporter-1 (OCT-1) influx transporter, and low OCT-1 activity in diagnostic chronic myeloid leukemia blood mononuclear cells is significantly associated with poor molecular response to imatinib. Herein we report that, in diagnostic chronic myeloid leukemia mononuclear cells and BCR-ABL1+ cell lines, peroxisome proliferator-activated receptor...

The incidence of reproductive disorders is constantly increasing and affects 15% couples, with male's abnormalities diagnosed in almost half the cases. male gonads exert two major functions testis productions gametes (exocrine function) sexual hormones (endocrine function). In last decades, next to steroid receptors such as estrogen androgen receptors, involvement other members nuclear receptor...

in this presentation, we review briefly on biogenesis of peroxisomes with regard to the recent findings on biogenesis. peroxisomes perform a range of various functions as oxidation of very long chain fatty acids, generation and removal of hydrogen peroxide, while peroxisomes have also been implicated in β-oxidation of aromatic and cyclic compounds, synthesis of plasmalogens, isoprenoids, lysine...

The present study was designed to investigate the pattern of time-dependent expression of peroxisome proliferator-activated receptors (PPARα, β, and γ) after global cerebral ischemia and reperfusion (I/R) damage in the rat hippocampus. Male Sprague Dawley (SD) rats were subjected to global cerebral I/R. The rat hippocampi were isolated to detect the expression of PPARs mRNA and protein levels a...

Kinase-linked receptors and nuclear receptors connect external cues to gene transcription. Among nuclear receptors, peroxisome proliferator-activated receptors (PPARs) are of special interest in relation to widespread human diseases. Mapping out connections between PPARs and kinase-linked receptor signaling is central to better understand physiological and pathophysiological processes and to be...

    Fibrates, as hypolipidemic drugs known as agonists of peroxisome proliferator-activated receptors, diminish inflammatory responses. Studies have shown that incorporation of a silicon atom into a drug structure improves its pharmacological potency, modifies its selectivity toward a given target, or changes its metabolic rate, in addition to increasing the lipophilicity of the compounds. A si...

Psoriasis is a polygenic, inflammatory and progressive disease, characterized by an abnormal differentiation and hyperproliferation of keratinocytes, associated with impaired immunologic activation and systemic disorders, while psoriatic arthritis is a chronic inflammatory articular disease. Pathophysiology of psoriasis comprises a dysfunction of the immune system cells with an interactive netw...

Peroxisome proliferator-activated receptors (PPARs) are transcriptional factors involved in the regulation of insulin resistance and adipogenesis. Cinnamon, a widely used spice in food preparation and traditional antidiabetic remedy, is found to activate PPARgamma and alpha, resulting in improved insulin resistance, reduced fasted glucose, FFA, LDL-c, and AST levels in high-caloric diet-induced...

A common building block for the synthesis of amorfrutin and cajaninstilbene acid derivatives has been developed. The library of synthesized compounds has enabled identification of new nontoxic ligands of peroxisome proliferator-activated receptors (PPAR) and potential inhibitors of the transcriptional corepressor protein NCoR. The biological data holds promise in identification of new potential...

A peroxisome proliferator-responsive element is located in the 5'-flanking region of the gene encoding rat hydratase-dehydrogenase, the second enzyme of the peroxisomal beta-oxidation pathway. DNase I footprint analysis with nuclear extracts from proliferator-responsive rat H4IIEC3 cells revealed two protected regions within the 196-base pair peroxisome proliferator-responsive element. Both reg...
