Application

La insulina humana se ha utilizado:
  • en el medio de cultivo necesario para la adipogénesis de las células madre adiposas (ASC)
  • para estudiar el efecto de la insulina en los cerebros de ratas jóvenes y envejecidos.
  • para estudiar el efecto de la insulina sobre las acciones inflamatorias del receptor 2 activado por proteasa (PAR2) utilizando un modelo de ratón.

Biochem/physiol Actions

Hormona polipeptídica bicatenaria producida por las células β de los islotes pancreáticos. Su peso molecular es de ~ 5800 Da) Las cadenas α y β se unen por dos enlaces disulfuro intercatenarios. La cadena α contiene un puente disulfuro intracatenario. La insulina regula la captación, utilización y almacenamiento celulares de glucosa, aminoácidos y ácidos grasos, e inhibe la hidrólisis de glucógeno, proteínas y grasas.

Glucose homeostasis and growth essentially depend on the hormone insulin engaging its receptor. Despite biochemical and structural advances, a fundamental contradiction has persisted in the current understanding of insulin ligand-receptor interactions. While biochemistry predicts two distinct insulin binding sites, 1

The role of insulin in the brain is still not completely understood. In the periphery, insulin can decrease inflammation induced by lipopolysaccharide (LPS); however, whether insulin can reduce inflammation within the brain is unknown. Experiments administrating intranasal insulin to young

Mammalian cells contain three closely related heterochromatin protein 1 (HP1) isoforms, HP1alpha, beta and gamma, which, by analogy to their unique counterpart in Schizosaccharomyces pombe, have been implicated in gene silencing, genome stability and chromosome segregation. However, the individual importance

Exogenous vertebrate-derived factors circulating in the blood have the capacity to modulate the biology of haematophagous insects. These include insulin, insulin growth factor 1 (IGF) and transforming growth factor β1 (TGFβ). The effects of the consumption of these three proteins

The recent development of a rat model that closely resembles the metabolic syndrome allows to study the mechanisms of amelioration of the syndrome by exercise training. Here, we compared the effectiveness for reducing cardiovascular risk factors by exercise training programmes
