Biomarkers and shear stress

Untitled

Costaining of pAkt-1S473 (red) and PECAM-1 (green) after 30 min flow-adaptation and 5 min ortho- (D) or retrograde flow (E). Image was obtained using Cat. No. 039200-301-J34L for p-Akt staining.

Research nowadays aims at working on models as similar as possible to the real physiological status. This includes the modification of cell culture conditions, For example, one should perform cell culture under “real” oxygen levels (e.g. hypoxia, normoxia, physioxia). For circulating cells, shear stress is a key factor, as cells behave in a different way depending on whether they are cultured under static or dynamic conditions. [Read more…]

Focus on the AKT cell signaling pathway…

AKT (Protein Kinase B or PKB), is a serine/threonine-specific protein kinase with known key involvement in glucose metabolism, apoptosis, cell proliferation, transcription and cell migration.
