ASK1: a new therapeutic target for kidney disease.

ASK1: a new therapeutic target for kidney disease. Am J Physiol Renal Physiol. 2016 May 25;:ajprenal.00208.2016 Authors: Tesch G, Ma FY, Nikolic-Paterson DJ Abstract Stress-induced activation of p38 MAPK and JNK signaling is a feature of both acute and chronic kidney disease and is associated with disease progression. Inhibitors of p38 MAPK or JNK activation provide protection against inflammation and fibrosis in animal models of kidney disease; however, clinical trials of p38 MAPK and JNK inhibitors in other diseases (rheumatoid arthritis and pulmonary fibrosis) have been disappointing. Apoptosis signal-regulating kinase 1 (ASK1) acts as an upstream regulator for the activation of p38 MAPK and JNK in kidney disease. Mice lacking the Ask1 gene are healthy with normal homeostatic functions and they are protected from acute kidney injury induced by ischemia-reperfusion and from renal interstitial fibrosis induced by ureteric obstruction. Recent studies have shown that a selective ASK1 inhibitor substantially reduced renal p38 MAPK activation and halted the progression of nephropathy in diabetic mice and this has led to a current clinical trial of an ASK1 inhibitor in patients with stage 3 or 4 diabetic kidney disease. This review explores the rationale for targeting ASK1 in kidney disease and the therapeutic potential of ASK1 inhibitors based on current experimental evidence.

ChallagundlaAbstractThe regulation of the pleiotropic transcription factor, nuclear factor-κB (NF-κB) by miRNAs and proteins is extensively studied. More recently, the NF-κB signaling was also reported to be regulated by several long non-coding RNAs (lncRNAs) that constitute the major portion of the noncoding component of the human genome. The common NF-κB associated lncRNAs include NKILA,...

This article has critically evaluated the research published after the 9th European Workshop in Periodontology in November 2012 to ascertain whether recent research has affected the merit of the manifesto. It was found that recent research supports the manifesto regarding diabetes mellitus, cardiovascular disease and adverse pregnancy outcomes, although further high-quality randomised controlled trials are required to support the manifesto statement that "certain populations of pregnant women may benefit from periodontal therapy." Furthermore, there is now good evidence from systematic reviews for an association ...

ABSTRACTDiabetes mellitus among older men has been associated with increased bone mineral density, but paradoxically increased fracture risk. Given the interactions among medication treatment, glycemic control, and diabetes ‐associated comorbidities, the relative effects of each factor remains unclear. This retrospective study includes 652,901 male Veterans age ≥65 years with diabetes and baseline hemoglobin A1c (HbA1c) value. All subjects received primary care in the Veterans Health Administration (VHA) from 2000 to 2010. Administrative data included ICD9 diagnoses and pharmacy records, and was linked to Medicare fee...

AbstractStrongyloides stercoralis (S. stercoralis), a human intestinal nematode, can lead to hyper/disseminated (HD) infection in patients treated with corticosteroids. Here, we report a case of strongyloidiasis in a 58-year-old female with a history of rheumatoid arthritis (RA) and type 2 diabetes mellitus (T2DM). The patient presented with abdominal pain and gastrointestinal (GI) bleeding. Stool was negative for parasitic agents in the first direct smear examination, and the patient with the probable diagnosis ofHelicobacter pylori (H. pylori) infection or Crohn ’s disease received antibiotics and corticosteroids. ...
