Characterization of the Rat Prodynorphin Gene [PDF]

open access: yesMolecular Endocrinology, 1989
The structure of full-length rat prodynorphin cDNA and the corresponding gene has been determined. The 2400 base rat prodynorphin mRNA is encoded by four exons. Exons 1 and 2 encode the majority of the 5'-untranslated sequence, while exons 3 and 4 contain the translated region; the entire 3' -untranslated region is contained on exon 4 as well.

Evolution of Proenkephalin and Prodynorphin [PDF]

open access: yesAmerican Zoologist, 1986
SYNOPSIS. Since the discovery of the enkephalins in 1975, three separate families of opioid peptides have been identified, proopiomelanocortin, proenkephalin, and prodynorphin. The lattertwo have multiple copies of the enkephalin sequence in larger enkephalin containing polypeptides (ECPs).

Parabrachial opioidergic projections to preoptic hypothalamus mediate behavioral and physiological thermal defenses

open access: yeseLife, 2021
Maintaining stable body temperature through environmental thermal stressors requires detection of temperature changes, relay of information, and coordination of physiological and behavioral responses. Studies have implicated areas in the preoptic area of

Functional bias of morphine and oliceridine under conditions of minor injury

open access: yesMolecular Pain, 2021
Recent reports suggest pain from surgical injury may influence the risks associated with exposure to opioids. In mice, hind-paw incision attenuates morphine-primed reinstatement due to kappa opioid receptor activation by dynorphin.

SEQUENCE ANALYSIS SUGGESTS POSITIVE SELECTION ON THE BOVINE PRODYNORPHIN GENE [PDF]

open access: yesBAG. Journal of Basic and Applied Genetics, 2020
Dynorphin A is an endogenous opioid peptide that is part of the KNDy system in the hypothalamus of mammals. This peptide acts as an inhibitor of the GnRH pulse generation, thus regulating the onset of puberty and reproductive cycles.

Ginsenoside Re protects methamphetamine-induced dopaminergic neurotoxicity in mice via upregulation of dynorphin-mediated κ-opioid receptor and downregulation of substance P-mediated neurokinin 1 receptor

open access: yesJournal of Neuroinflammation, 2018
Background We previously reported that ginsenoside Re (GRe) attenuated against methamphetamine (MA)-induced neurotoxicity via anti-inflammatory and antioxidant potentials.

Effect of PDYN rs2281285, rs2235749 and rs910080 gene polymorphisms on the intensity of depression symptoms and negative craving in heroin addicts [PDF]

open access: yesArchives of Biological Sciences, 2021
The present study was undertaken to explore whether prodynorphin (PDYN) polymorphisms have an effect on the intensity of depressive symptoms and negative craving in heroin addicts in a sample of 100 heroin addicts and 108 controls.

RETRACTED: Alcohol drinking alters stress response to predator odor via BNST kappa opioid receptor signaling in male mice

open access: yeseLife, 2020
Maladaptive responses to stress are a hallmark of alcohol use disorder, but the mechanisms that underlie this are not well characterized. Here, we show that kappa opioid receptor signaling in the bed nucleus of the stria terminalis (BNST) is a critical ...

Striatal fosB Expression Is Causally Linked with l-DOPA-Induced Abnormal Involuntary Movements and the Associated Upregulation of Striatal Prodynorphin mRNA in a Rat Model of Parkinson's Disease

open access: yesNeurobiology of Disease, 1999
Rats with unilateral dopamine-denervating lesions sustained a 3-week treatment with a daily l-DOPA dose that is in the therapeutic range for Parkinson's disease.

Ancient and recent positive selection transformed opioid cis-regulation in humans.

open access: yesPLoS Biology, 2005
Changes in the cis-regulation of neural genes likely contributed to the evolution of our species' unique attributes, but evidence of a role for natural selection has been lacking.
