Pterostilbene is equally potent as resveratrol in inhibiting 12‐O‐tetradecanoylphorbol‐13‐acetate activated NFκB, AP‐1, COX‐2, and iNOS in mouse epidermis

Abstract: Resveratrol, a phytoalexin present in grapes, has been reported to inhibit multistage mouse skin carcinogenesis. Recent studies showed that topically applied resveratrol significantly inhibited cyclooxygenase-2 (COX-2) expression and activation of nuclear factor-kappaB (NF-kappaB) induced by tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA) in mouse epidermis. The aim of the present study was to further explore the effect of resveratrol on TPA-induced signaling pathways in mouse epidermis and to compare with its dimethylether, pterostilbene. Resveratrol and pterostilbene significantly reduced activator protein 1 (AP-1) and NF-kappaB activation. In the case of AP-1, the binding of c-Jun subunit was particularly affected, while only slight effect on c-Fos binding to TPA-responsive element (AP-1 binding consensus sequence) (TRE) site was observed. Both stilbenes inhibited the activation of NF-kappaB by blocking the translocation of p65 to the nucleus and increasing the retention of IkappaBa in the cytosol. The latter might be related to decreased activity of IkappaB kinase and/or proteasome 20S. Reduced activation of transcription factors decreased the expression and activity of COX-2 and inducible nitric oxide synthase (iNOS). In most assays, pterostilbene was either equally or significantly more potent than resveratrol. Pterostilbene might show higher biological activity due to its possible better bioavailability, since substitution of hydroxy with methoxy group increases lipophilicity.

Estimating Global Burden of Disease due to congenital anomaly : An analysis of European data

Abstract: Objective To validate the estimates of Global Burden of Disease (GBD) due to congenital anomaly for Europe by comparing infant mortality data collected by EUROCAT registries with the WHO Mortality Database, and by assessing the significance of stillbirths and terminations of pregnancy for fetal anomaly (TOPFA) in the interpretation of infant mortality statistics. Design, setting and outcome measures EUROCAT is a network of congenital anomaly registries collecting data on live births, fetal deaths from 20 weeks’ gestation and TOPFA. Data from 29 registries in 19 countries were analysed for 2005–2009, and infant mortality (deaths of live births at age Results According to WHO, 17%–42% of infant mortality was attributed to congenital anomaly. In 11 EUROCAT countries, average infant mortality with congenital anomaly was 1.1 per 1000 births, with higher rates where TOPFA is illegal (Malta 3.0, Ireland 2.1). The rate of stillbirths with congenital anomaly was 0.6 per 1000. The average TOPFA prevalence was 4.6 per 1000, nearly three times more prevalent than stillbirths and infant deaths combined. TOPFA also impacted on the prevalence of postneonatal survivors with non-lethal congenital anomaly. Conclusions By excluding TOPFA and stillbirths from GBD years of life lost (YLL) estimates, GBD underestimates the burden of disease due to congenital anomaly, and thus declining YLL over time may obscure lack of progress in primary, secondary and tertiary prevention.
