Registered report: Kinase-dead BRAF and oncogenic RAS cooperate to drive tumor progression through CRAF

279 views | Jun 11 2018

Bhargava A et al. indicated that Heidorn and colleagues report that paradoxical activation of the RAF-RAS-MEK-ERK pathway by BRAF inhibitors when applied to BRAF(WT) cells is a result of BRAF/CRAF heterodimer formation upon inactivation of BRAF kinase activity, and occurs only in the context of active RAS.

N-3 polyunsaturated fatty acids increase hepatic fibroblast growth factor 21 sensitivity via a PPAR-γ-β-klotho pathway

936 views | Jun 11 2018

Yang W et al. indicated n-3 PUFAs increase hepatic FGF21 sensitivity and β-klotho expression probably through a PPAR-γ-dependent mechanism, and may thereby exert hepatic beneficial effects on lipid metabolism. [Read the Full Post]

Impairment of hypoxia-induced HIF-1α signaling in keratinocytes and fibroblasts by sulfur mustard is counteracted by a selective PHD-2 inhibitor

1348 views | Jun 10 2018

Deppe J, et al. described a pathomechanism by which SM negatively affects hypoxia-stimulated HIF-1α signaling in keratinocytes and fibroblasts and thus possibly contributes to delayed wound healing in SM-injured patients that could be treated with PHD-2 inhibitors. [Read the Full Post]

Encapsulation of curcumin in polyelectrolyte nanocapsules and their neuroprotective activity

960 views | Jun 10 2018

Szczepanowicz K et al. indicated the utility of PLL/PGA shell nanocapsules as a promising, alternative way of curcumin delivery for neuroprotective purposes with improved efficiency and reduced toxicity. [Read the Full Post]

Structural and Functional Role of Acetyltransferase hMOF K274 Autoacetylation

262 views | Jun 09 2018

McCullough CE et al. pointed to the critical and specific role of hMOF Lys-274 autoacetylation in hMOF stability and cognate substrate acetylation and argues that binding of Ac-CoA to hMOF likely drives Lys-274 autoacetylation for subsequent cognate substrate acetylation. [Read the Full Post]
