Protein kinase a transgenes: the many faces of cAMP.
The -adrenergic receptor/adenylyl cyclase/protein kinase A (PKA) axis is the central signaling pathway that serves to stimulate cardiac function. It is classically perceived as a linear signaling cascade (Figure), and cAMP is thought to be the second messenger responsible for the positive inotropic, chronotropic, and lusitropic effects of catecholamines. New data gained from a series of transge...
متن کاملExpression of Anaplastic Lymphoma Kinase Protein in Human Breast Cancer
Background & Objectives: Anaplastic lymphoma Kinase (ALK) is a receptor tyrosine kinase involved in the genesis of several human cancers. ALK was initially identified because of its involvement in anaplastic large cell lymphoma (ALCL). ALK is believed to foster tumorigenesis following activation by autocrine and/or paracrine growth loops. Studies reveal that the presence of anti-ALK antibodies ...
متن کاملTHE EFFECT OF THEOPHYLLINE ON THE KINETICS OF cAMP-DEPENDENT PROTEIN KINASE CATALYTIC SUBUNIT, cAMP, PROTEIN KINASE INHIBITOR AND THEIR RELATIONSHIP IN LUNG TISSUE
We have investigated the effect of theophylline on the kinetics of the catalytic subunit of protein kinase and related factors in lung tissue. The results show that the point of highest concentration of the C subunit of protein kinase which is active in casein phosphorylation is at 3h of incubation time, but in the presence of 100 Ilg/ InL and 10µg/mL theophylline, this is shifted to I.S an...
متن کاملProtein kinase A anchoring.
Specificity is perhaps the most enigmatic property of hormonemediated signaling pathways, especially when one considers that more than 30 hormones employ the ubiquitous second messengers, Ca, phospholipid, or cAMP, to relay messages from the cell membrane to intracellular effectors. In most cases the net signaling effect is to activate protein kinases or phosphoprotein phosphatases, which, in t...
متن کاملProtein Kinase Cε in the Platelet and Hippocampal Tissue as a Diagnostic Biological Marker in Alzheimer Disease
Introduction: Alzheimer disease (AD) is a neurodegenerative disorder characterized by the progressive loss of memory and other cognitive functions. Protein kinase Cε (PKCε) is an isoform that most effectively suppresses amyloid beta (Aβ) production and synaptic loss. Methods: In this study, spatial learning and memory for treated rats were evaluated by the Morris water maze test. The activity ...
