Am J Reprod Immunol 2011; 66: 527–533 Problem  Polycystic ovary syndrome (PCOS) is a common gynecological endocrine disorder. This study was to evaluate whether insulin receptor substrate (IRS)-2 Gly1057Asp polymorphism influences chronic inflammatory parameters in Taiwanese patients with PCOS. Method of

study  DNA was extracted from whole blood samples for genotyping and detection of IRS-2 Gly1057Asp polymorphism in 129 PCOS women and 109 control women. Selleck Trichostatin A Ninety-seven PCOS women accepted metformin treatment for 3 months, and low-grade chronic inflammatory markers were assessed. Results  selleck compound The

levels of IL-6 were significantly elevated in PCOS women compared with normal women. Among allelic variant of IRS-2, concentrations of IL-6 were greater in IRS-2 homozygous Asp population. Treatment with metformin significantly reduced IL-6, especially in PCOS patients with IRS-2 homozygous Asp variant. Conclusion  The results showed that IL-6 may be an early low-grade chronic inflammatory marker among PCOS patients with IRS-2 polymorphism in Taiwanese population. This pharmacologic study in IRS-2 polymorphism may provide more information Sorafenib for preventing long-term complications in PCOS. “
“Pyriproxyfen is a juvenile hormone mimic of vital importance for insect development with little risk to humans. This study was performed to investigate whether large doses of pyriproxyfen affect the immune response in mammals. Mice were immunized thrice with ovalbumin in 5% ethanol, with or without pyriproxyfen or alum. Large doses of pyriproxyfen (9 or 15 mM) significantly enhanced specific total IgG immune response. This enhancement was no longer present 24 hr after treatment with

pyriproxyfen. These results suggest that pyriproxyfen is a safe chemical. Moreover, pyriproxyfen induced higher titers of IgG2a and enhanced tumor necrosis factor-alpha and gamma-interferon responses whereas alum induced IgG1 with enhanced interleukin-4 and -10. These observations indicate that the mechanism of immune enhancement by pyriproxyfen may differ from that of alum. Juvenile hormones are a group of sesquiterpenes that regulate diverse aspects of insect physiology and ensure the growth and development of larvae while preventing metamorphosis [1]. Several JHAs that are stable in the environment and mimic the biological action of JH as insect growth regulators, including methoprene, fenoxycarb and pyriproxyfen, have been synthesized [2]. Although the mechanisms of action of JHs remain unclear, the lipophilic nature of sesquiterpene JHs suggests an intracellular receptor-mediated action.
