In the present study, selected ESCM actively proliferated for only about 3 to 6 days, before a significant reduction in proliferation occurred.
We reasoned that this effect could be the result of either a reduction in proliferation or an increase in cell death.
-JQ1 treatment also promoted withdrawal from the cell cycle, although this reduction in proliferation was shown to be independent of its anti-differentiation activity.
A forebrain-specific loss of Rac1 leads to an SVZ-specific reduction in proliferation, a concomitant increase in cell cycle exit, and premature differentiation.
Thus, RNAi mediated silencing of Nf-kB subunits in DLBCL cells with these mutations leads to dramatic reduction in proliferation, compared to DLBCL cells that harbor other non Nf-kB related mutations.
We hypothesized that this reduction in proliferation was due to C4S-mediated overactivation of fibroblast growth factor receptor 3 (FGFR3).
Treatment with triparanol, an inhibitor of Hedgehog signaling, resulted in a 60% decrease in tumor volume, a 30% decrease in cellularity, and a 20% reduction in proliferation rate.
ANALYSIS OF beta-CATENIN PROTEIN EXPRESSION IN LIVER TISSUE AND INTESTINAL ADENOMAS: Adenomas harvested from mice treated for 7 days with beta-catenin AODNs demonstrated clear downregulation of beta-catenin expression, which was accompanied by a significant reduction in proliferation.
What did correlate was the occurrence of the adhesion defect and the observed reduction in proliferation.
If the latter interpretation is correct there should be a similar reduction in proliferation in all tissues in kto mutant embryos, but such a general reduction in proliferation was not detected in a previous study [7].
Almost 50% of the analyzed mutants showed significant reduction in proliferation efficiency, with 20% displaying severe defects.
