Bracken fern-induced malignant tumors in rats: absence of mutations in p53, H-ras and K-ras and no microsatellite instability

Specific codon 13 K-ras mutations are predictive of clinical outcome in colorectal cancer patients, whereas codon 12 K-ras mutations are associated with.. Moerkerk P, Arends JW,

In the current study, we have evaluated the radiation- induced modulation of EGFR, ERCC1 and p53 in cervical cancer cell lines and in malignant tissues from 10 patients diagnosed

Phosphorimages of high mobility DNA adducts detected in calf thymus DNA modified in vitro with APT (A) and the upper gastrointestinal tract of mice following treatment with bracken

Therefore, our results suggest that liver mutations in exons 5, 6, 7 and 8 of TP53 gene and exons 1 and 2 of H-RAS and K-RAS genes are not among the early molecular

The ability of US in estimating the size of malignant tumors was 71%, compared to 100% of benign tumors (p=0.03), with no significant difference between SGCT and NSGCT.. Necrosis

In the present study, we identified mutations in exons 9 and 20 of the PIK3CA gene in primary breast tumors from Brazilian breast cancer patients, and we analyzed the

gastric samples with microsatellite instability, our results indicate that genetic alterations of the APC gene commonly present in colorectal tumors are infrequent in sporadic
