Defective FGFR1 Signaling Disrupts Glucose Regulation: Evidence From Humans With Mutations.

Context: Activation of fibroblast growth factor receptor 1 (FGFR1) signaling improves the metabolic health of animals and humans, while inactivation leads to diabetes in mice. Direct human genetic evidence for the role of FGFR1 signaling in human metabolic health has not been fully established.

Objective: We hypothesized that individuals with naturally occurring variants ("experiments of nature") will display glucose dysregulation.

Chitosan Nanoparticles Potentiate the in vitro and in vivo Effects of Curcumin and other Natural Compounds.

The development of biodegradable nanoparticles is an important tool for the biological transport of chemical compounds. The nanoencapsulation reduces the biopharmaceutical and pharmacokinetic drawbacks of compounds and enhances their biological properties. Naturally occurring polymers such as proteins and polysaccharides have been widely applied in the development of nanostructured systems of several therapeutic agents.

Animal models for genetic neuromuscular diseases.

The neuromuscular disorders are a heterogeneous group of genetic diseases, caused by mutations in genes coding sarcolemmal, sarcomeric, and citosolic muscle proteins. Deficiencies or loss of function of these proteins leads to variable degree of progressive loss of motor ability. Several animal models, manifesting phenotypes observed in neuromuscular diseases, have been identified in nature or generated in laboratory.
