Intracellular Signalling: Switching off signals [PDF]
In hematopoietic cells, the protein tyrosine phosphatase PTP1C appears to play a central role in the termination of signalling by receptors that activate protein tyrosine kinases.

Loss of Pkd1 limits susceptibility to colitis and colorectal cancer
Colorectal cancer (CRC) is one of the most common cancers, with an annual incidence of ~135,000 in the US, associated with ~50,000 deaths. Autosomal dominant polycystic kidney disease (ADPKD), associated with mutations disabling the PKD1 gene, affects as

The urinary bladder "mucosa" or innermost portion of the bladder is composed of transitional epithelium, basement membrane, and the lamina propria. This chapter reviews the specialized anatomy of the bladder epithelium (urothelium) and speculates on possible communication mechanisms from urothelial cells to various cell types within the bladder wall ...

Inhibition of hypothalamic leukemia inhibitory factor exacerbates diet-induced obesity phenotype
Background The consumption of large amounts of dietary fats can trigger an inflammatory response in the hypothalamus and contribute to the dysfunctional control of caloric intake and energy expenditure commonly present in obesity.

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

Hedgehog (Hh) proteins constitute one family of a small number of secreted signaling proteins that together regulate multiple aspects of animal development, tissue homeostasis and regeneration. Originally uncovered through genetic analyses in Drosophila, their subsequent discovery in vertebrates has provided a paradigm for the role of morphogens in ...

Mechanodetection of neighbor plants elicits adaptive leaf movements through calcium dynamics
Plants detect their neighbors via various cues, including reflected light and touching of leaf tips, which elicit upward leaf movement (hyponasty). It is currently unknown how touch is sensed and how the signal is transferred from the leaf tip to the ...

Calcium ions (Ca(2+)) impact nearly every aspect of cellular life. This review examines the principles of Ca(2+) signaling, from changes in protein conformations driven by Ca(2+) to the mechanisms that control Ca(2+) levels in the cytoplasm and organelles.

Inducible disruption of TET dioxygenases in mouse embryonic stem cells results in chromosome mis-segregation and aneuploidies, due to Khdc3 downregulation suggesting a role for TET enzymes and DNA methylation patterns in maintaining genome stability.

Therapeutic approaches targeting CD95L/CD95 signaling in cancer and autoimmune diseases
Cell death plays a pivotal role in the maintenance of tissue homeostasis. Key players in the controlled induction of cell death are the Death Receptors (DR).
