Vhl deletion in renal epithelia causes HIF-1 α-dependent, HIF-2α-independent angiogenesis and constitutive diuresis.
Vhl deletion in renal epithelia causes HIF-1α-dependent, HIF-2α-independent angiogenesis and constitutive diuresis. Oncotarget. 2016 Aug 12; Authors: Schönenberger D, Rajski M, Harlander S, Frew IJ Abstract One of the earliest requirements for the formation of a solid tumor is the establishment of an adequate blood supply. Clear cell renal cell carcinomas (ccRCC) are highly vascularized tumors in which the earliest genetic event is most commonly the biallelic inactivation of the VHL tumor suppressor gene, leading to constitutive activation of the HIF-1α and HIF-2α transcription factors, which are known angiogenic factors. However it remains unclear whether either or both HIF-1α or HIF-2α stabilization in normal renal epithelial cells are necessary or sufficient for alterations in blood vessel formation. We show that renal epithelium-specific deletion of Vhl in mice causes increased medullary vascularization and that this phenotype is completely rescued by Hif1a co-deletion, but not by co-deletion of Hif2a. A physiological consequence of changes in the blood vessels of the vasa recta in Vhl-deficient mice is a diabetes insipidus phenotype of excretion of large amounts of highly diluted urine. This constitutive diuresis is fully compensated by increased water consumption and mice do not show any signs of dehydration, renal failure or salt wasting and blood electrolyte levels remain unchanged. Co-deletion of Hif1a, bu...

CONCLUSION: The proposed PHARMAC criteria will give access to these important drugs to those people with T2DM who will likely benefit the most. PMID: 33032305 [PubMed - in process]
Authors: Peng C, Cohen DJ Abstract INTRODUCTION: Esophageal squamous cancer remains an important cause of mortality worldwide with two new immunotherapy drugs recently approved for metastatic disease. AREAS COVERED: The authors review the epidemiology and genomics of esophageal squamous cell carcinoma. They also examine prior trials involving targeted agents under investigation as well immunotherapies that have been approved and novel combinations. EXPERT OPINION: Great advances have been made in characterizing the molecular changes in esophageal carcinoma. However, relatively few drugs have shown benefit i...
Authors: Siamashvili M, Davis S Abstract INTRODUCTION: Bromocriptine mesylate quick release (QR) is a dopamine D2 receptor agonist and is the only oral, primarily centrally acting drug that can be used for the treatment of adults with type 2 diabetes. AREAS COVERED: The authors describe current recommendations on the use of bromocriptine mesylate QR. Major efficacy and safety parameters of the late phase trials, including The Cycloset Safety Trial, have been identified and presented. EXPERT OPINION: Efficacy of bromocriptine mesylate QR monotherapy appears to be low but is compensated by favorable safety pr...

TYPE 2 diabetes may feel like a minefield - can you eat this or that without spiking blood sugar levels? If you're feeling peckish, what's a good, healthy option for lunch?
CONCLUSIONS: Young adult IS patients in Korea exhibit low awareness and poor management of their risk factors. Although the short-term outcome was relatively favorable in those patients, having SLE was associated with unfavorable outcomes. More attention needs to be paid for improving awareness and controlling risk factors in this population. PMID: 33029967 [PubMed]
ConclusionWe consider that this technique is useful, however, we have to exercise care in malignant cases as the true-positive rate may be low.
