Накратко на български

Фосфорилирането на хистидина в протеините се изучава чрез генетично модифицирани мишки, за да се види как влияе върху теглото и метаболизма. Това помага за разбирането на механизмите при затлъстяването и диабета тип 2.

Histidine Phosphorylation and Obesity

Protein histidine phosphorylation is a poorly characterized post-translational modification. Its importance in mammalian cellular function is emerging from the discovery of histidine kinases and phosphatases and their substrates. Recently, histidine phosphorylation has been involved in heart failure and cancer. Obesity and type 2 diabetes remain challenging disorders due to growing prevalence around the world and poorly efficient treatments. Regarding metabolic disorders, histidine phosphorylation state has been associated with insulin secretion regulation in pancreas. However, the role of histidine phosphorylation in insulin sensitivity in liver, skeletal muscle or adipose tissue and/or in obesity is still not known. The main aim of the present project was to determine whether protein histidine phosphorylation plays a role in obesity-associated metabolic dysfunction. Thus, we determined if obesity modify global histidine phosphorylation level, histidine kinases and phosphatases expression or activity, and specific protein histidine phosphorylation. Then, we wanted to evaluate whether a change of histidine phosphorylation level can impact whole-body glucose metabolism and body weight/composition by using transgenic mice deficient in the main histidine phosphatase, LHPP.
