Griseofulvin strongly suppressed the dynamic instability of individual microtubules in live MCF-7 cells by reducing the rate and extent of the growing and shortening phases.
GF (15 μM) reduced the time microtubules spent in growing and shortening phases by 53 and 31%, respectively while increased the time microtubule spent in the pause state (neither growing nor shortening detectably) by 103% compared to the control microtubules.
Adaptive dose-response designs are being considered as a means of shortening phase IIb studies and creating a seamless interface with phase III.
Further analysis revealed that nGO-PEG (1 1) treatment significantly accelerated FtsZ-ring assembly, shortening Phase 1 in the bacterial cell cycle.
(3) A post-transpression Shortening Phase, with large-scale, upright, open folds formed during minor N S shortening along the length of the belt (a phase of deformation correlated with high-angle convergence in the Inland Branch of the Damara Orogen at 530 510 Ma).
Compared with the normal controls, rats with acute liver injury had a significantly prolonged interdigestive MMC cycle, related mainly to longer MMC Phases I and IV, shortened MMC Phase III, and MMC Phase II characterized by increased migrating clustered contractions, which were probably major contributors to the gastrointestinal motility disorders.
Studies of ESCs have shown that their rapid cell division is associated with an unusual cell cycle composed of a predominant S phase and a markedly shortened G1 phase, compared to differentiated cells (Savatier et al., 1994; Savatier et al., 1996; White et al., 2005).
m Shortening Phases II and III could by itself reduce the expected cost of a new drug by 18%.
Each experiment included an abridged (shortened) nursery phase of 1 year.
In one study, Gd-based nanoparticles were used, with 250 kV photon irradiation, to kill SQ20B cells for increased DNA breaks and shortened G2/M phase blockage.
