Microvascular complications of diabetes 6

Pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis.

翻译后修饰

  • Nitrated under oxidative stress. Nitration coupled with oxidation inhibits the catalytic activity
  • Acetylation at Lys-122 decreases enzymatic activity. Deacetylated by SIRT3 upon exposure to ionizing radiations or after long fasting (By similarity)
  • Polyubiquitinated; leading to proteasomal degradation. Deubiquitinated by USP36 which increases protein stability
