Appetite regulation and metabolism -
The highly homologous, long half-life GLP-1 analog, liraglutide, has also been demonstrated as a well-tolerated body weight-reducing pharmacological agent in humans, yet transient nausea remains to be the most common side effect.
With the known additive satiating effects of GLP-1 and PYY, exploiting endogenous GLP-1 production may also yield a novel combinatorial anti-obesity approach. Early work in rats on a peptide with inhibitory action on stomach oxyntic glands lead to the advent of the name OXM for the now well established gut hormone.
Despite the probable involvement of the GLP-1 receptor in OXM signaling, the pathways are likely separate. Eliciting comparable satiating effects to GLP-1, along with the already well demonstrated anti-obesity potential of GLP-1, OXM may equally present as a strong gut hormone candidate for combating against the obesity epidemic.
The prevalence of obesity and its associated co-morbidities has increased substantially in the last number of decades, and the disease is now widely considered to be a global epidemic.
Currently, among approved anti-obesity therapies, only GI surgery can effectively lead to substantial weight loss results, accompanied by long-term sustainability. There has, however, been increasingly convincing evidence that the resulting weight loss following the surgery is due, at least in part, to an alteration in the circulating levels and physiology of certain gut hormones.
Although the gut-brain axis and a variety of hormone signaling pathways have been emerging as potentially powerful anti-obesity tools, the short half-life of many of the endogenous gut hormones must be considered.
The evidence presented herein strongly indicates that obesity research and the development of weight loss or weight management products should focus on the release and function of gut hormones, in connection to their association with receptors in the CNS, in particular the hypothalamus.
