The protein encoded by PDYN is a preproprotein that is proteolytically processed to form the secreted opioid peptides beta-neoendorphin, dynorphin, leu-enkephalin, rimorphin, and leumorphin.

Genetic and epigenetic factors within PDYN are related to risk for alcoholism.
These results indicate that KOR (show OPRK1 ELISA Kits) can form a heterodimer with B2R (show BDKRB2 ELISA Kits) and this leads to increased protein kinase A activity by the CREB (show CREB1 ELISA Kits) signaling pathway, leading to a significant increase in cell proliferation.
This study found a significant haplotype-by-sex interaction, suggesting association with alcohol dependence in males but not females. The findings suggest that sex-dependent effects of PDYN variants in alcohol dependence are phenotype-specific.
PDYN gene promoter polymorphism might contribute to familial-risk temporal lobe epilepsy. (Review, meta-analysis)
The results demonstrate that DYN 1-17 and certain N-terminal fragments, produced in an inflamed environment, play an anti-inflammatory role by inhibiting NF-kappaB (show NFKB1 ELISA Kits)/p65 translocation.
Enhanced event-related potentials amplitudes suggest a hyper-active performance monitoring system in high PDYN expression individuals, and this might also be an indicator of a higher risk for internalizing disorders
This study generated the first mouse model for SCA23 and shown that mice expressing PDYN-R212W recapitulate many characteristics of the human phenotype of SCA23
Studied differential DNA-protein interactions of PDYN and OPRK1 (show OPRK1 ELISA Kits) SNPs significantly associated with alcohol dependence.
REST represses PDYN expression in SH-SY5Y cells and the adult human brain and may have implications for mental health and brain/mental disorders.
This study demonistratedn that Neurocognitive and neuroinflammatory correlates of PDYN mRNA expression in the anterior cingulate in postmortem brain of HIV-infected subjects.
Mechanical allodynia produced by monosodium iodoacetate (MIA (show MIA ELISA Kits)) was enhanced in mice lacking KOR (show OPRK1 ELISA Kits) or PDYN gene. In contrast with the nociceptive manifestations induced by osteoarthritis, the increased microglial expression on the lumbar section of the spinal cord after MIA (show MIA ELISA Kits) administration was similar in KOR (show OPRK1 ELISA Kits)-KO, PDYN-KO and WT littermates. Moreover, anhedonic- and anxiolytic-like states were revealed after MIA (show MIA ELISA Kits) administration.
steroidal environment and energy state negatively regulate kisspeptin (Kiss1 (show KISS1 ELISA Kits)), neurokinin B (Tac2), and dynorphin (Pdyn) gene expression.
These pathways are consistent with previously reported behavioral and biochemical phenotypes that typify mice lacking ENT1 (show SLC29A1 ELISA Kits). Moreover, we validated decreased expression of the SNARE complex protein VAMP1 (synaptobrevin-1 (show VAMP1 ELISA Kits)) in the dHip as well as decreased expression of pro-dynorphin (PDYN), neuroendocrine convertase (PCSK1 (show PCSK1 ELISA Kits)), and Leu-Enkephalin (dynorphin-A) in the nucleus accumbens
DYN-A(2-17) interacts with Orexin A in the paraventricular hypothalamic nucleus to modulate food intake in mice.
We found potential links between the alterations in expression of Tsc22d3 (show TSC22D3 ELISA Kits), Nfkbia (show NFKBIA ELISA Kits) and Pdyn, and different aspects of susceptibility to stress.
This study identify that photostimulation of dyn-expressing cells in discrete subregions within the NAcSh drive opposing motivational behavioral states
The results of this study indicated that PDYN have a differential role in cue-induced reinstatement of cocaine-seeking behavior.
Double NPY (show NPY ELISA Kits) and dynorphin deletion resulted in heavier mice, with increased adiposity, despite no significant changes in food intake or UCP-1 (show UCP1 ELISA Kits) activity.
These findings identify a unique cellular process by which orexin (show OX ELISA Kits) can occlude the reward threshold-elevating effects of coreleased dynorphin and thereby act in a permissive fashion to facilitate reward.
Data suggest that activation of neurokinin 3 and kappa-opioid receptors (NK3R (show TACR3 ELISA Kits) and KOR (show OPRK1 ELISA Kits)) excites and inhibits kisspeptin, neurokinin B (NKB), and dynorphin (KNDy neurons).
The investigation of Dyn (show SPTBN4 ELISA Kits) A 1-17 metabolism at the blood-brain barrier (BBB (show ALMS1 ELISA Kits)) is important since the metabolites exhibit unique biological functions compared to the parent compound.
The Xen-dorphin prohormone is a new opioid-like prohormone distinct from proenkephalin (show PENK ELISA Kits) and prodynorphin.
The expression of the genes coding for proopiomelanocortin (POMC (show POMC ELISA Kits)), proenkephalin (PENK (show PENK ELISA Kits)) and prodynorphin (PDYN) in porcine luteal cells isolated from corpora lutea (CL) collected on days 3-6, 8-10 and 13-16 of the oestrous cycle is reported.
Influence of age and 17beta-estradiol on kisspeptin, neurokinin B, and prodynorphin gene expression in the arcuate-median eminence.
The protein encoded by this gene is a preproprotein that is proteolytically processed to form the secreted opioid peptides beta-neoendorphin, dynorphin, leu-enkephalin, rimorphin, and leumorphin. These peptides are ligands for the kappa-type of opioid receptor. Dynorphin is involved in modulating responses to several psychoactive substances, including cocaine. Multiple alternatively spliced transcript variants encoding the same protein have been found for this gene.
