Opioid precursor protein isoform is targeted to the cell nuclei in the human brain [PDF]

open access: yes, 2017
Background: Neuropeptide precursors are traditionally viewed as proteins giving rise to small neuropeptide molecules. Prodynorphin (PDYN) is the precursor protein to dynorphins, endogenous ligands for the kappa-opioid receptor.

Hyperpolarization Modulation of the T-Type hCa<sub>v</sub>3.2 Channel by Human Synenkephalin [1-53], a Shrew Neurotoxin Analogue without Paralytic Effects. [PDF]

open access: yesAngew Chem Int Ed Engl
Human synenkephalin [1–53] (hSYN), an analogue peptide of shrew saliva neurotoxins, was synthesized and its structural characteristics studied. Synthetic hSYN potently activated the T‐type voltage‐gated Ca channel hCav3.2 but did not paralyze mealworms. These findings offer new insight into neurological disorder treatment and evolutionary mechanisms of

Biomimetic Chemistry on Tandem Protein/Lipid Damages under Reductive Radical Stress

open access: yesCHIMIA, 2008
The study of radical stress in the biological environment needs a comprehensive vision of all possible reactive species and their mechanisms. Among them, reductive stress is evaluated for its selective target of sulfur-containing compounds.

p-Cresol and p-Cresyl Sulphate Boost Oxidative Stress: A Systematic Review of Recent Evidence. [PDF]

open access: yesBasic Clin Pharmacol Toxicol
ABSTRACT Recent studies have emphasized the significant role of p‐cresol and its conjugated form, p‐cresyl sulphate (PCS), in enhancing oxidative stress, leading to potential detrimental effects on various biological systems. Both p‐cresol and PCS contribute to increased production of reactive oxygen species (ROS), which can result in tissue damage ...

Multi-physics Extension of OpenFMO Framework

open access: yes, 2007
OpenFMO framework, an open-source software (OSS) platform for Fragment Molecular Orbital (FMO) method, is extended to multi-physics simulations (MPS). After reviewing the several FMO implementations on distributed computer environments, the subsequent ...

Acetaldehyde‐enkephalins: pronounced changes in the opiate activity of methionine‐enkephalin and leucine‐enkephalin on reaction with acetaldehyde [PDF]

open access: yesFEBS Letters, 1980
We have shown that the two major endogenous opioid peptides, methionine-enkephalin and leucineenkephalin [ 1,2] (enkephalin [Met’] and enkephalin[Leu’]) rapidly react with acetaldehyde in aqueous buffers to give a stable ‘acetaldehyde-enkephalin’ adduct, referred to as ‘acetaldehyde-enkephalin[Met’]’ and ‘acetaldehyde-enkephalin [Leu’]‘, respectively ...

Dnmt3a regulates emotional behavior and spine plasticity in the nucleus accumbens. [PDF]

open access: yes, 2010
Despite abundant expression of DNA methyltransferases (Dnmts) in brain, the regulation and behavioral role of DNA methylation remain poorly understood. We found that Dnmt3a expression was regulated in mouse nucleus accumbens (NAc) by chronic cocaine use ...

White Adipose Tissue Browning and Cross Talk With Metabolic Diseases and Tumors: From Molecular Mechanisms to Clinical Translation

open access: yesMed Research, EarlyView.
White adipose tissue undergoes browning under endogenous and exogenous stimuli, primarily regulated by core molecules such as PRDM16 and UCP1. It exhibits a double‐edged sword effect in metabolic diseases and tumors: while mitigating metabolic disease impacts and suppressing early‐stage tumors through nutritional competition, it may accelerate cachexia
