Ras
Definition:
(n.) See 2d Reis.
Example Sentences:
(1) The effects of hormonal promotion of T24-ras oncogene-transfected rat embryo fibroblasts (REF) were compared to cotransformation of these cells with adenovirus E1A and ras.

(3) Here we co-inject RB protein with c-myc, EJ-ras, c-fos or c-jun protein.
(4) These results suggest that a certain minimum level of expression of c-myc is required for the maintenance of ras transformation in NIH 3T3 cells.
(5) This is the first clear example of activation of the K-ras gene by ethylating agents in a rodent lung tumor system.
(6) A total of 28 cell lines were selected for Geneticin - resistance and inoculated into the footpads of syngeneic animals following co-transfection with pSV2neo and genomic DNA, or transfection with plasmid constructs containing neo and the activated Ha-ras oncogene.
(7) In the second study, CFA, TiterMax, Adjuvax and RAS were compared in rabbits, mice and goats.
