Relevant evidence for this has come from adult fMRI research; for example, Grant, Courtemanche, and Rainville (2011) found that proficient meditators display less activation in brain regions of executive functioning (lateral and medial PFC, ACC) while attending to pain.
In addition, all three are synthetic lethal with mrc1deletion [ 36]. pol2-16, which lacks the N-terminal (residues 176 to 1,134), is checkpoint proficient but displays a slow progression of the replication fork [ 41], while pol2 11, which lacks a fraction of its C-terminal, is checkpoint deficient [ 32, 42].
RB-proficient cells displayed a significant decrease in DNA replication upon exposure to CDDP, independent of p53 status.
As a direct test of cellular senescence, RB-proficient cells displayed a 4- to 5-fold increase in β-galactosidase staining over both the untreated control cells and the RB-deficient cells in the absence or presence of CDDP (Figure 2B, right panel).
Lead compounds from two different chemical series, represented by compounds 17 and 38, displayed proficient in vitro reactivation of GF-inhibited hAChE, while also possessing low inhibition of native enzyme.
Bearing in mind these reports and their implication that the C-terminal domain of Chk1 may have a negative impact on its catalytic activity, we might have expected that the checkpoint proficient Chk1D469G mutant would display an elevated level of kinase activity both in the absence and presence of damage.
Indeed there is a high likelihood that health workers who are highly proficient, client-oriented and display adaptive and proactive behaviours, will demonstrate high responsiveness towards clients.
The D384Med cells, which were proficient in both pathways, displayed intermediate sensitivity.
Mucosal cells derived from a normal biopsy (patient ID 18) displayed more proficient DNA maturation after a chase period of only 1 h (P<0.01).
Furthermore, RB-proficient p53DD cells displayed a senescent-like morphology as early as 2 days after exposure to CDDP, while RB-deficient cells grew uninhibited in the presence of CDDP (Figure 2B, left panel).
