Nutritional abundance associated with chronic inflammation and dyslipidemia impairs the functioning of endoplasmic reticulum (ER) thereby hampering cellular responses to insulin. PHLPP1 was identified as a phosphatase which inactivates Akt, the master regulator of insulin mediated glucose homeostasis. Given the suggestive role of PHLPP1 phosphatase in terminating insulin signalling pathways, deeper insights into its functional role in inducing insulin resistance are warranted. Here, we show that PHLPP1 expression is enhanced in skeletal muscle of insulin resistant rodents which also displayed ER stress, an important mediator of insulin resistance...

The expression of fibroblast growth factor receptor (FGFR)-1 correlates with angiogenesis and is associated with prostate cancer (CaP) progression. To more precisely define the molecular mechanisms whereby FGFR1 causes angiogenesis in the prostate we exploited a transgenic mouse model, JOCK-1, in which activation of a conditional FGFR1 allele in the prostate epithelium caused rapid angiogenesis and progressive hyperplasia. By labeling the vasculature in vivo and applying a novel method to measure the vasculature in three dimensions, we were able to observe a significant increase in vascular volume 1 week after FGFR1 activation...
