Our finding that abrogation of a ribosomal protein causes a specific G1 arrest confirms the strength of the refined Tet model for conditional gene knockdown.
An alternative hypothesis would be that abrogation of cell cycle arrest precedes apoptosis.
Recently, we reported that abrogation of LPA receptor 1 (LPamelioratedated murine collagen-induced arthritis, probably via inhibition of inflammatory cell migration, Th17 differentiation and osteoclastogenesis.
We surmise that abrogation of nuclear 100-kDa E-cadherin and β-catenin expression following butyrate treatment is related to the control of E-cadherin gene transcription.
Moreover, we have demonstrated that the tumor phenotype of HMGB1-secreting human MM cells requires HMGB1 for continued growth, and that abrogation of HMGB1 function may have therapeutic efficacy.
Recently, it has also been found that abrogation of Suv4-20h decreases the heterochromatic mark H4K20me3 at telomeric regions and facilitates telomere replenish during reprogramming (Marion et al., 2011).
We conclude that abrogation of respiration suppresses apoptosis and ROS production in a strongly proliferating cell population on solid media.
We have already demonstrated that abrogation of E-cadherin in mES cells does not affect their pluripotency [17], [18].
These results demonstrate that abrogation of E-cadherin mediated cell-cell contact results in increased ES cell proliferation.
This indicates that abrogation of the inhibitory effect of Notch signaling in the niche may promote the expansion of primitive cells, thus facilitating evolution of prostate tumors.
Finally, we demonstrated that abrogation of glycogen synthesis, by knock-down of GYS1 expression, impairs hypoxic preconditioning, suggesting a physiological role for the glycogen accumulated during chronic hypoxia.
