Nicotine Effects and the Endogenous Opioid System

Journal of Pharmacological Sciences, 2014
.: Nicotine (NIC) is an exogenous ligand of the nicotinic acetylcholine receptor (nAChR), and it influences various functions in the central nervous system. Systemic administration of NIC elicits the release of endogenous opioids (endorphins, enkephalins,

Changes in Liver Metabolome Induced by Pterostilbene and Resveratrol in a Rat Model of Liver Steatosis

Molecular Nutrition &Food Research, Volume 69, Issue 15, August 2025.
Resveratrol and pterostilbene reduced the steatotic status of animals fed a high‐fat, high‐sucrose diet, involving differential and specific mechanisms of action for each stilbene. Thus, changes in riboflavin metabolism, nicotinamide mononucleotide metabolism, or in the LysoPC(18:1)‐mediated effects contribute to the specific actions of pterostilbene ...

Opioid receptors in cardiovascular function

British Journal of Pharmacology, Volume 182, Issue 16, Page 3710-3725, August 2025.
Opioid receptors are G protein‐coupled receptors expressed by various cells in the heart, including myocytes and nerve fibres, and play a crucial role in modulating cardiac function. These receptors influence neural transmission, heart rate and myocyte contractility, offering cardioprotection.

Hyperpolarization Modulation of the T‐Type hCav3.2 Channel by Human Synenkephalin [1–53], a Shrew Neurotoxin Analogue without Paralytic Effects

Angewandte Chemie, Volume 137, Issue 27, July 1, 2025.
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

Multi‐Omics Analyses on Maya‐Land Tomatoes Shed Light on Plant Strategies to Thrive in High Temperatures

Physiologia Plantarum, Volume 177, Issue 4, July/August 2025.
ABSTRACT Heat stress limits tomato yield and quality. Deciphering the key genes and metabolites related to heat tolerance is essential for selecting tolerant varieties. In this study, we profiled the transcriptomes and metabolomes of roots and shoots in response to heat stress from a Maya‐land ecotype of heirloom tomato (Calkiní), which grows in ...
