Research Overview

Omentin-1

Lower omentin-1 levels are often associated with obesity, insulin resistance, and metabolic syndrome. Research continues on its use as a biomarker and as a mechanistic lead for AMPK-linked metabolic interventions.

hGHRH(1-44)

Human GHRH(1-44) amide has been used extensively to characterize hypothalamic control of pituitary somatotrophs and the downstream GH/IGF-1 axis. It remains a standard comparator in studies of GHRH agonism, secretion dynamics, and receptor pharmacology.
