Epicatechin induces NF-kappa B, activator rotein-1 (AP-1) and nuclear transcription factor erythroid 2p45-related factor-2 (Nrf2) via phosphatidylinositol-3-kinase/protein kinase B (PI3K/AKT) and extracellular regulated kinase (ERK) signalling in HepG2 cells [PDF]
The dietary flavonoid epicatechin has been reported to exhibit a wide range of biological activities. The objective of the present study was to investigate the time-dependent regulation by epicatechin on the activity of the main transcription factors (NF-

Protein kinase A-dependent phosphorylation of B/K protein [PDF]
We have previously isolated a novel protein "B/K" that contains two C2-like domains. Here, we report the isolation and mRNA distribution of a human B/K isoform, and protein kinase A (PKA)-dependent phosphorylation of the B/K protein. The 1.5 kb human B/K cDNA clone exhibits 89% and 97% identities with rat B/K in the sequences of nucleotide and amino ...

Interaction between Yeast Cdc6 Protein and B-Type Cyclin/Cdc28 Kinases [PDF]
During purification of recombinant Cdc6 expressed in yeast, we found that Cdc6 interacts with the critical cell cycle, cyclin-dependent protein kinase Cdc28.

Mechanism of Protein Kinase B Activation by Cyclic AMP-Dependent Protein Kinase [PDF]
Activation of protein kinase B (PKB) by growth factors and hormones has been demonstrated to proceed via phosphatidylinositol 3-kinase (PI3-kinase). In this report, we show that PKB can also be activated by PKA (cyclic AMP [cAMP]-dependent protein kinase) through a PI3-kinase-independent pathway. Although this activation required phosphorylation of PKB,

Distinct signalling pathways mediate insulin and phorbol ester- stimulated eukaryotic initiation factor 4F assembly and protein synthesis in HEK 293 cells [PDF]
Stimulation of serum-starved human embryonic kidney (HEK) 293 cells with either the phorbol ester, 12-O-tetradecanoylphorbol-13-acetate (TPA), or insulin resulted in increases in the phosphorylation of 4E-BP1 and p70 S6 kinase, eIF4F assembly, and ...

Regulated Association of Protein Kinase B/Akt with Breast Tumor Kinase [PDF]
Increased protein-tyrosine kinase activity is a prognostic indicator of decreased disease-free survival in patients with advanced breast tumors. Breast tumor kinase (Brk) is a soluble protein-tyrosine kinase overexpressed in the majority of breast cancers and also in normal skin and gut epithelium, but not in normal breast epithelial cells.
