Screening of human bladder tumors and urine sediments for the presence of H-ras mutations.

Abstract excerpt

A series of 111 human bladder tumors were screened using oligonucleotide mutant specific probes, restriction enzyme analysis and single-stranded confirmation polymorphism (SSCP) for the presence of H-ras activation events. Thirty-three tumors were found to harbor H-ras mutations where a glycine to valine (G-->T) change in codon 12 was the most common point mutation recorded (26 tumors). Additional mutations...
