Calmodulin Activates Phosphatidylinositol 3-Kinase [PDF]
Calmodulin and phosphatidylinositol 3-kinase are vital components of a number of common intracellular events. Calmodulin, a ubiquitous Ca2+-dependent effector protein, regulates multiple processes in eukaryotic cells, including cytoskeletal organization, vesicular trafficking, and mitogenesis.

The recruitment and activation of phosphatidylinositol 4-phosphate 5-kinases α critically regulate CD28-dependent signaling responses [PDF]
CD28 costimulatory receptor is a crucial determinant of the outcome of T lymphocyte activation. The engagement of CD28 by its natural ligands, B7.1/CD80 or B7.2/CD86, expressed on the surface of professional APC, lowers T cell receptor (TCR) activation ...

Inhibition of PI3K/Akt signaling suppresses epithelial-to-mesenchymal transition in hepatocellular carcinoma through the Snail/GSK-3/beta-catenin pathway [PDF]
Background/Aims Patients with advanced hepatocellular carcinoma (HCC) have a poor prognosis due to the lack of effective systemic therapies. Epithelial-to-mesenchymal transition (EMT) is a pivotal event in tumor progression, during which cancer cells ...

Signaling pathways for transduction of the initial message of the glycocode into cellular responses [PDF]
The sugar units of glycan structures store information and establish an alphabet of life. The language of the oligosaccharide coding units is deciphered by receptors such as lectins and the decoded message can be transduced by multiple signaling pathways.

Phosphatidylinositol 3‐kinases in tumor progression [PDF]
Many cellular processes have been identified in which phosphatidylinositol 3‐kinase has a key regulatory function. As an oncogene, it is also involved in the development of cancer. The transformation and progression of normal cells towards an advanced stage tumor and/or towards metastatic lesions involves a complex series of events, including genetic ...
