What's the difference between ras and was?

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.
  • (2) Large gender differences were found in the correlations between the RAS, CR, run frequency, and run duration with the personality, mood, and locus of control scores.
  • (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.
  • (8) One week after initiation is 1-2 months before the appearance of benign papillomas that harbor activated Ha-ras oncogenes when the initiated mice are promoted with the tumor promoter phorbol 12-myristate 13-acetate.
  • (9) The other three oncogenes namely c-K-ras, c-H-ras and c-myc, were not detected in these two carcinomas or the non-cancerous liver tissue adjacent to the carcinomas.
  • (10) Thus, a4 and a2 alleles of the c-Ha-ras-1 may perhaps be viewed as genetic markers of predisposition to lung, ovarian and thyroid cancer, respectively, in combination with other clinical parameters.
  • (11) Additionally, the amount of mRNAs for preproenkephalin as well as for the cellular proto-oncogenes c-myc, c-fos and c-H-ras, which are thought to be mediators of intracellular signal transduction, was determined in hippocampus in these same animals.
  • (12) The degree of staining for ras 11 was significantly related to the grade of differentiation and increased from Dukes stage A to C. Strong staining for ras 11 predicted a significantly shorter recurrence-free interval (p less than 0.001).
  • (13) The effects of oxidant stress were studied in immortalised hamster (BHK-21) and rat (208F) cell lines before and after transformation to the malignant state with polyoma virus, or activated H-ras, respectively.
  • (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.
  • (16) These cell lines also overexpress the Ha-ras proto-oncogene.
  • (17) In one patient with gastric carcinoma a c-Ha-ras-1 overexpression was detected due to its amplification both in tumour tissues and in regional metastasis.
  • (18) Our study gives further evidence that erb B, myc, Ha-ras and fos proto-oncogenes are involved in the control of cell growth and in the process of rat hepatocarcinogenesis.
  • (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.

Was


Definition:

  • (imp.) of Be
  • (v.) The first and third persons singular of the verb be, in the indicative mood, preterit (imperfect) tense; as, I was; he was.
