This may be a reflection of the fact that PCa metastasis is not as dependant on abrogation of cell proliferation control as compared with other factors such as loss of cell cell/cell extracellular matrix adhesion, increased cell motility, basement membrane penetration, angioneogenesis, and immune escape through impaired expression of surface tumour antigens (Hrouda and Kirby, 1998).
Hoy acknowledges that one of the biggest changes he has faced in adapting to motor racing is the abrogation of some level of control – that things on track will occur about which you can do nothing – not least at Le Mans where the closing speeds between the four classes of cars is huge.
For example, abrogation of either Golgi quality control (Δvps10, Δgga1, Δtul1) or ER quality control (Δdoa10, Δhrd1, Δire1) systems significantly enhanced the PM integrity defect observed for Δart1 mutant cells during heat stress.
This suggests that transformation of DSBR-deficient cells follows abrogation of specific cell-cycle control and apoptosis mechanisms, and results in genetic instability and tumor progression along distinguishable pathways.
As expected, because of low levels of pAkt (Serine 473) in MDA-MB-231 cells, treatment with LY294002 resulted in complete abrogation of pAkt in both control and Runx2 knockdown cells.
It may be that TGF-beta growth inhibition occurs via multiple mechanisms and that the loss of one pathway during tumour progression does not necessarily result in the abrogation of TGF-beta-induced growth control.
LNCaP cells are also sensitive to IL-6 as an interesting study demonstrated that IL-6 exposed tumors injected into nude mice demonstrated an abrogation of proteins involved in cell cycle control.
In addition, it would seem that showing the control of a mutant with abrogation of the RNA binding could be useful in the stress granule assays.
As control for pharmacological inhibition of ATM, abrogation of Chk2 phosphorylation was evaluated and shown to be reduced (Fig. 4C).
It reversely follows that its absence may be involved in an increase in the burden of acute infectious viral loads and abrogation of virus-specific cellular immune responses, leading to initial control failure in HIV infections.
