Experiments with gene-targeted mice showed that Bim is required for the death of thymocytes in response to growth factor withdrawal, calcium flux, taxol treatment, as well as strong T cell receptor ligation (6, 7).
The pro-apoptotic BH3-only protein Bim has been shown to be essential for the initiation of several pathways that induce apoptosis in thymocytes (7), including cytokine withdrawal and calcium flux.
These results suggest that an increased withdrawal of metabolite flux from the Calvin cycle to increase the rate of glycolysis may represent an important mechanism in combating butanol toxicity.
"The rules around withdrawal are still in flux, and they may change by August," Landis says.
Bim is critical for the apoptosis of lymphocytes evoked by diverse cytotoxic insults, including cytokine withdrawal and deregulated calcium flux, 14 and contributes modestly to DNA damage-induced apoptosis, 15 even though the bim gene lacks a binding site for the tumour suppressor p53.
The influence of parametric modulation of the crystal withdrawal rate and the mass flux of dissolved matter into a crystallizer upon both the neutral stability surface of steady states and the amplitude and frequency of auto-oscillating regimes of continuous crystallization are investigated.
These included gene expression, cell adhesion, bioenergetics, glutamate toxicity, cell death, calcium flux, and trophic factor withdrawal.
Trump's planned withdrawals from Afghanistan and Syria are in something of a state of flux, in large part because of concerns among military brass and Republicans about pulling out too quickly and leaving a vacuum.
Xc is the critical sludge concentration determining the limiting flux FL (total flux resulted from the gravity settling rate and applied sludge-withdrawal rate) for the underflow concentration Xu (Metcalf and Eddy 1998).
This indicated higher relative fluxes in the non-oxidative part of the PPP when compared to the rate of withdrawal of pentose phosphates to His biosynthesis.
