Review of Kyotorphin Research: A Mysterious Opioid Analgesic Dipeptide and Its Molecular, Physiological, and Pharmacological Characteristics

open access: yesFrontiers in Medical Technology, 2021
Tyrosine-arginine (kyotorphin), an opioid analgesic dipeptide, was discovered more than 40 years ago in 1979. The evidence accumulated during this period has established the physiological significance of kyotorphin as a neuromodulating peptide, and ...

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

open access: yesCell 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 ...

Effects of rearing conditions on behaviour and endogenous opioids in rats with alcohol access during adolescence. [PDF]

open access: yesPLoS ONE, 2013
Causal links between early-life stress, genes and later psychiatric diagnoses are not possible to fully address in human studies. Animal models therefore provide an important complement in which conditions can be well controlled and are here used to ...

Thermodynamics and Kinetics of Folding of a Small Peptide

open access: yes, 2001
We study the thermodynamics and kinetics of folding for a small peptide. Our data rely on Monte Carlo simulations where the interactions among all atoms are taken into account.

Opioids in breast cancer: Between analgesia and modulation of tumour progression

open access: yesBritish Journal of Pharmacology, EarlyView.
Preclinical investigations consistently demonstrate that activation of μ‐opioid receptors and δ‐opioid receptors promote proliferation, migration, angiogenesis, epithelial‐mesenchymal transition, acquisition of cancer stem cell phenotypes, and chemoresistance.

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

open access: yesCell 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.

Structure of the Energy Landscape of Short Peptides

open access: yes, 2002
We have simulated, as a showcase, the pentapeptide Met-enkephalin (Tyr-Gly-Gly-Phe-Met) to visualize the energy landscape and investigate the conformational coverage by the multicanonical method.

Effect of different agonistic experiences on behavioural seizures in fully amygdala kindled rats [PDF]

open access: yes, 1992
Fully amygdala kindled rats were exposed to two different inter-male agonistic experiences in order to study the interaction between epilepsy and acute social stress.

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

open access: yesThe FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...
