Targeted Cell Reprogramming Produces Analgesic Chromaffin-Like Cells from Human Mesenchymal Stem Cells

Cell Transplantation, 2013
Transplantation of allogeneic adrenal chromaffin cells demonstrated the promise of favorable outcomes for pain relief in patients. However, there is a very limited availability of suitable human adrenal gland tissues, genetically well-matched donors in ...

Methionine Enkephalin Suppresses Osteocyte Apoptosis Induced by Compressive Force through Regulation of Nuclear Translocation of NFATc1

JBMR Plus, 2020
Mechanical stress stimulates bone remodeling, which occurs through bone formation and resorption, resulting in bone adaptation in response to the mechanical stress. Osteocytes perceive mechanical stress loaded to bones and promote bone remodeling through

Genetically Engineered Human Mesenchymal Stem Cells Produce Met-Enkephalin at Augmented Higher Levels in Vitro

Cell Transplantation, 2006
We have reported that transplantation of adrenal medullary chromaffin cells that release endogenous opioid peptides into pain modulatory regions in the CNS produce significant antinociceptive effects in patients with terminal cancer pain.

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

CHIMIA, 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.

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

FEBS 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 ...

Cancer‐related pain: A bidirectional modulator of cancer progression

Clinical and Translational Medicine, Volume 16, Issue 9, September 2026.
CRP and tumour progression engage in a dynamic, bidirectional circuit mediated by multiple mechanisms involving neuroimmunology and cancer ‐neuroscience. Analgesic interventions may affect tumour progression, while anticancer therapies can influence pain. Targeting pain in cancer may have promising therapeutic value in cancer progression.

Proteome‐Wide Prediction of Putative Bemisia tabaci Effector Candidates and Transient Validation of BtApe‐Mediated Suppression of Tomato Immune Responses

Archives of Insect Biochemistry and Physiology, Volume 122, Issue 3, July 2026.
The workflow illustrates the process of identifying and preliminarily validating the functionality of effectors in Bemisia tabaci. The proteome of B. tabaci served as the initial input for a multiparameter effector prediction pipeline, which integrates secretory features, subcellular targeting predictions, and parallel computational tools to generate a

Sensory Neuropeptides and Endogenous Opioids Expression in Human Dental Pulp with Asymptomatic Inflammation: In Vivo Study

Mediators of Inflammation, 2015
Purpose. This study quantified the expression of substance P (SP), calcitonin gene-related peptide (CGRP), β-endorphins (β-End), and methionine-enkephalin (Met-Enk) in human dental pulp following orthodontic intrusion. Methods.

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,
