Resistance of Sézary cells to TNF‐α‐induced apoptosis is ...

2012-4-1 · Abstract: Failure to execute an apoptotic programme is one of the critical steps and a common mechanism promoting tumorogenesis. Immediate early responsive gene 3 (IER3) has been shown to be upregulated in several cancers. IER3 is a stress‐induced gene, which upregulation leads to reduction in production of reactive oxygen species (ROS) protecting malignant cells from apoptosis. We observed ...

Cell disruption for microalgae biorefineries

2015-3-1 · Cell disruption is thus achieved through high-pressure impact (shear forces) of the accelerated fluid jet on the stationary valve surface as well as hydrodynamic cavitation from the pressure drop induced shear stress (Chisti and Moo-Young, 1986, Halim et al., 2012a, Halim et al., 2012b). Cavitation is defined as a 3-step phenomenon taking place ...
