Estradiol treatment prevents injury induced enhancement in spinal cord dynorphin expression.
Administration of the ovarian steroid estradiol in male and female animals has been shown to have neuromodulatory and neuroprotective effects in a variety of experimental models. In the present study, spinal tissues from dermatomes just above (T5-7, at

Enhanced dynorphin expression and secretion in pancreatic beta-cells under hyperglycemic conditions
Objective: Dynorphin, an endogenous opioid peptide predominantly expressed in the central nervous system and involved in stress response, pain, and addiction, has intrigued researchers due to its expression in pancreatic β-cells.
