Inhibition of Food Intake by PACAP in the Hypothalamic Ventromedial Nuclei is Mediated by NMDA Receptors [PDF]

open access: yes, 2014
Central injections of pituitary adenylate cyclase-activating polypeptide (PACAP) into the ventromedial nuclei (VMN) of the hypothalamus produce hypophagia that is dependent upon the PAC1 receptor; however, the signaling downstream of this receptor in the

MicroRNAs as the critical regulators of protein kinases in prostate and bladder cancers

open access: yesEgyptian Journal of Medical Human Genetics, 2021
Background Bladder cancer (BCa) and prostate cancer (PCa) are frequent urothelial and genital malignancies with a high ratio of morbidity and mortality which are more common among males.

Rapamycin induces transactivation of the EGFR and increases cell survival. [PDF]

open access: yes, 2009
The mammalian target of rapamycin (mTOR) signaling network regulates cell growth, proliferation and cell survival. Deregulated activation of this pathway is a common event in diverse human diseases such as cancers, cardiac hypertrophy, vascular ...

The Jak/STAT signaling pathway is downregulated at febrile temperatures. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: The Janus family of kinases (JAKs), Jak1, Jak2, Jak3, and Tyk2, constitute a subgroup of non-receptor protein tyrosine kinases. Upon cytokine binding, the receptor-associated kinases are activated and phosphorylate tyrosine residues in their ...

Activation of tyrosine kinases by mutation of the gatekeeper threonine. [PDF]

open access: yes, 2008
Protein kinases targeted by small-molecule inhibitors develop resistance through mutation of the gatekeeper threonine residue of the active site. Here we show that the gatekeeper mutation in the cellular forms of c-ABL, c-SRC, platelet-derived growth ...

Evidence of the presence of calcium/calmodulin-dependent protein kinase IV in human sperm and its involvement in motility regulation [PDF]

open access: yes, 2005
The mechanisms involved in the regulation of mammalian sperm motility are not well understood. Calcium ions (Ca(2+)) have been suggested to play a key role in the maintenance of motility; nevertheless, how Ca(2+) modulates this process has not yet been ...

Protein-tyrosine phosphorylation in Bacillus subtilis: a 10-year retrospective

open access: yesFrontiers in Microbiology, 2015
The discovery of tyrosine-phosphorylated proteins in Bacillus subtilis in the year 2003 was followed by a decade of intensive research activity. Here we provide an overview of the lessons learned in that period.

Phospho.ELM:a database of experimentally verified phosphorylation sites in eukaryotic proteins [PDF]

open access: yes, 2004
BACKGROUND: Post-translational phosphorylation is one of the most common protein modifications. Phosphoserine, threonine and tyrosine residues play critical roles in the regulation of many cellular processes.

Hanks-Type Serine/Threonine Protein Kinases and Phosphatases in Bacteria: Roles in Signaling and Adaptation to Various Environments [PDF]

open access: yes, 2018
Reversible phosphorylation is a key mechanism that regulates many cellular processes in prokaryotes and eukaryotes. In prokaryotes, signal transduction includes two-component signaling systems, which involve a membrane sensor histidine kinase and a ...
