The hypothalamus integrates peripheral signals and modulates food intake and energy expenditure by regulating the metabolic function of peripheral tissues, including the liver and adipose tissue. In a previous study, we demonstrated that s-resistin, an intracellular resistin isoform highly expressed in the hypothalamus and upregulated during aging, is important in the central control of energy homeostasis, affecting mainly the peripheral response to insulin by still unknown mechanisms. Herein, using an intracerebroventricular injection of a specific lentiviral RNAi against s-resistin, we assessed, in the Wistar rat, the effects of central s-resistin downregulation on the expression and phosphorylation levels of intermediates involved in insulin signaling and the inflammatory response in epididymal white adipose tissue (eWAT) and liver.

Article Synopsis
  • Rigid spine syndrome is a rare condition in children marked by progressive scoliosis, neck and spine stiffness, muscle weakness, and breathing issues, primarily linked to genetic variations in the SELENON gene.
  • Recent research identified additional genetic variants in the HMGCS1 gene in five patients, suggesting it plays a role in this syndrome, despite it not being previously linked to any diseases.
  • Functional studies of the HMGCS1 variants showed altered protein stability and activity, and experiments in zebrafish indicated that these mutations severely impact development, but can be rescued by introducing healthy HMGCS1 mRNA.
