Alexander V. Sirotkin “The role of protein kinases in control of ovarian functions”

2667 views | Sep 13 2011

Control of basic physiological processes including reproduction requires multilevel signaling system, which includes hormones, growth factors and related molecules, their receptors and binding proteins, whose alter expression of target genes via protein kinases (PKs) and transcription factors. These signaling substances can control reproductive processes via production, binding and metabolism of regulators of cell cycle, apoptosis, secretory activity, differentiation and oogenesis.

Boosani “Endogenous angiogenesis inhibitors affecting cell survival pathways”

2433 views | Sep 13 2011

Phosphatidylinositol 3-kinases (PI3 kinases) are a group of enzymes categorized into three different classes, among them class I isoforms are well characterized (Stein, 2001). These kinases are the key enzymes that are vital for cell survival with essential role in several cellular functions such as growth, proliferation, differentiation, motility, and intracellular signaling. PI3 Kinases are activated by tyrosine kinases with Akt being the downstream effector molecule (Hennessy et al., 2005). [Read the Full Post]

Novel CDK2 Inhibitors as Anti-Tumor Agents

2420 views | Sep 09 2011

Conventional anti-cancer drugs have mainly focused on targeting DNA synthesis and cell division.n order to avoid these adverse effects, investigators begin to develop a new class of anti-cancer agents, and signal transduction or secondary message inhibitors is one of the successful research findings.

HDACs, play important roles in kidney development

5458 views | Sep 08 2011

Histone deacetylases (HDACs) regulate fundamental biological processes such as cellular proliferation, differentiation, and survival via genomic and non-genomic effects. Some data suggest that HDACs may play a important role in kidney development. [Read the Full Post]

p38 MAPK inhibitor, FR167653, a potent therapy against PTHrP-induced osteoclastogenesis and bone resorption-related diseases

3113 views | Sep 07 2011

Study on mechanism indecates that PTHrP stimulates osteoclastogenesis by increasing receptor activator of NF-kB ligand (RANKL) expression. p38 MAPK is required for osteoclast differentiation. This implies the existence of relationship between p38 MAPK and PTHrP in osteoclastogenesis. [Read the Full Post]

FGFs and the downstream signaling involve in tissue regeneration

4084 views | Sep 06 2011

FGFs have the biological activity of inducing cell proliferation, migration, differentiation, and angiogenesis. As one of the critical components in tissue regeneration, fibroblast growth factors (FGFs) shown the potential effects on the repair and regeneration of tissues. [Read the Full Post]

PI3K/Akt inhibition modulates multidrug resistance

4483 views | Sep 05 2011

Multidrug resistance (MDR), characterized by cancer cell resistance to multiple chemotherapeutic drugs, is a major clinical obstacle in the treatment of hematological malignancies. And many investigators have comfirmed that the PI3K/Akt pathway is associated with chemoresistance in cancer cells. [Read the Full Post]
