The implementation of the Plan Esperanza and response to the imPACT Review.

Following the implementation of the National Cancer Prevention and Control Results-based Budget Programme (PpR Cancer-024) in 2011, the Peruvian Government approved the Plan Esperanza-a population-based national cancer control plan-in 2012. Legislation that ensured full government-supported funding for people who were otherwise unable to access or afford care and treatment accompanied the Plan. In 2013, the Ministry of Health requested an integrated mission of the Programme of Action for Cancer Therapy (imPACT) report to strengthen cancer control in Peru.

Hypoxia-inducible factor-1 mediates neuronal expression of the receptor for advanced glycation end products following hypoxia/ischemia.

Activation of the receptor for advanced glycation endproducts (RAGE) by its multiple ligands can trigger diverse signaling pathways with injurious or pro-survival consequences. In this study, we show that Rage mRNA and protein levels were stimulated in the mouse brain after experimental stroke and systemic hypoxia. In both cases, RAGE expression was primarily associated with neurons.

Structural and functional adaptation to hypoxia in the rat brain.

Chronic exposure to a hypoxic environment leads to structural and functional adaptations in the rat brain. One significant adaptation is a decrease in intercapillary distances through a near doubling of the capillary density, which begins after about 1 week of hypoxic exposure and is completed by 3 weeks. Hypoxic angiogenesis is controlled by activation of downstream genes by Hypoxia Inducible Factor-1 and Angiopoietin-2.

Inhibitors of mitochondrial complex I attenuate the accumulation of hypoxia-inducible factor-1 during hypoxia in Hep3B cells.

Hypoxia-inducible factor 1 (HIF-1) is a heterodimeric transcription factor that regulates transcriptional activation of several genes that are responsive to oxygen lack, including erythropoietin, vascular endothelial growth factor, various glycolytic enzymes and the GLUT-1 glucose transporter. Because mitochondria have been postulated to be involved in the regulation of HIF-1, we tested the effects of mitochondrial electron transport chain complex I inhibitors, rotenone and 1-methyl-4-phenylpiridinium (MPP(+)), on hypoxic-induced accumulation of HIF-1 alpha, the regulated component of the dimer. We found, consistent with our previous observations in Cath.

Role of nitric oxide in the regulation of HIF-1alpha expression during hypoxia.

Hypoxia-inducible factor-1 (HIF-1), a heterodimeric transcription factor consisting of HIF-1alpha and HIF-1beta subunits, controls the expression of a large number of genes involved in the regulation of cellular responses to reduced oxygen availability. The oxygen-regulated subunit, HIF-1alpha, is stabilized in cells exposed to hypoxia. The regulation of hypoxic responses by nitric oxide (NO) is believed to have wide pathophysiological relevance, thus we investigated whether NO affects HIF-1 activation in hypoxic cells.
