(14) Upon stimulation with NGF, the percentage of Ras.GTP increased to 24% after 2 min, and the high level of Ras.GTP was maintained for at least 16 h. On the other hand, the activation of Ras by FGF and IL-6 showed distinct kinetics; about 3-fold increase of Ras.GTP was detected at 10 min, and afterward, the level returned to the basal level within 60 min.
(15) Transfection with normal and activated C-H-ras oncogenes only led to increases in the IC50s of alkylating agents.

(19) The Wap-ras gene was stably introduced into the mouse germ line of five transgenic mice (one male and four females).
(20) These results suggest that ras, fos, mos, src, and erbB-2 use a common cellular pathway for transforming cells.

(4) A semi-automated quantitative fluorescence image analysis (QFIA) technique was developed with the Leitz TAS-Plus to detect bladder cancer using hyperploidy in urinary cells.
(5) Because the low thymidine and folic acid condition of medium 199 is known to induce chromosome and chromatid gaps and breaks at folate-sensitive fragile sites, other fragile site-induction regimes were examined to determine if the TAs seen in GM6892A were due to a fragile site in the Yq12 band.
