2013 APR 23 (NewsRx) — By a News Reporter-Staff News Editor at Life Science Weekly — Researchers detail new

data in Peptide Proteins. According to news reporting originating in Ottawa, Canada, by NewsRx journalists, research

stated, “An important disease among human metabolic disorders is type 2 diabetes mellitus. This disorder involves multiple

physiological defects that result from high blood glucose content and eventually lead to the onset of insulin resistance.”

The news reporters obtained a quote from the research from Carleton University, “The combination of insulin resistance,

increased glucose production, and decreased insulin secretion creates a diabetic metabolic environment that leads to a

lifetime of management. Appropriate models are critical for the success of research. As such, a unique model providing

insight into the mechanisms of reversible insulin resistance is mammalian hibernation. Hibernators, such as ground squirrels

and bats, are excellent examples of animals exhibiting reversible insulin resistance, for which a rapid increase in body

weight is required prior to entry into dormancy. Hibernator studies have shown differential regulation of specific molecular

pathways involved in reversible resistance to insulin. The present review focuses on this growing area of research and

the molecular mechanisms that regulate glucose homeostasis, and explores the roles of the Akt signaling pathway during

hibernation. Here, we propose a link between hibernation, a well-documented response to periods of environmental stress,

and reversible insulin resistance, potentially facilitated by key alterations in the Akt signaling network, PPAR-gamma/PGC-1

alpha regulation, and non-coding RNA expression. Coincidentally, many of the same pathways are frequently found to be

dysregulated during insulin resistance in human type 2 diabetes.”

According to the news reporters, the research concluded: “Hence, the molecular networks that may regulate reversible

insulin resistance in hibernating mammals represent a novel approach by providing insight into medical treatment of insulin

resistance in humans.”
