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

Protein tyrosine kinases couple the interleukin‐2 receptor to p21ras
AbstractThe T cell growth factor interleukin‐2 (IL‐2) induces p21ras activation in T lymphocytes. We have previously shown that a protein kinase C (PKC)‐mediated pathway for p21ras regulation exists in T cells and that the IL‐2 receptor (IL‐2R) can couple to p21ras independently of the presence of the PKC pathway for p21ras regulation.

Receptor protein tyrosine kinase EphB4 is up-regulated in colon cancer [PDF]
We have used commercially available cDNA arrays to identify EphB4 as a gene that is up-regulated in colon cancer tissue when compared with matched normal tissue from the same patient.Quantitative RT-PCR analysis of the expression of the EphB4 gene has shown that its expression is increased in 82% of tumour samples when compared with the matched normal ...

Severe B Cell Deficiency in Mice Lacking the Tec Kinase Family Members Tec and Btk [PDF]
The cytoplasmic protein tyrosine kinase Tec has been proposed to have important functions in hematopoiesis and lymphocyte signal transduction. Here we show that Tec-deficient mice developed normally and had no major phenotypic alterations of the immune ...

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

Novel protein kinase signaling systems regulating lifespan identified by small molecule library screening using Drosophila. [PDF]
Protein kinase signaling cascades control most aspects of cellular function. The ATP binding domains of signaling protein kinases are the targets of most available inhibitors. These domains are highly conserved from mammals to flies.

The power of microRNA regulation—insights into immunity and metabolism
MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...
