Considering its frequency, high mortality rate as well as many etiological mysteries colorectal cancer is a challenge to contemporary science. In our study we analyzed RER + and RER--phenotypes and their relations with clinical-pathological characteristics of sporadic colorectal cancers. We also analyzed genetic alterations of tumor suppressor genes as well as their relation with microsatellite...

Microsatellites or simple sequence repeats (SSRs) have become the most popular source of genetic markers, which are ubiquitously distributed in many eukaryotic and prokaryotic genomes. This is the first study examining and comparing SSRs in completely sequenced genomes of the Bovidae. We analyzed and compared the number of SSRs, relative abundance, relative density, guanine-cytosine (GC) conten...

A number of human genes containing coding mononucleotide repeat sequences are particularly prone to mutations in tumors with defects in mismatch repair (MMR) genes (MSI-H cancers). In a large series of MSI-H colorectal tumors, we looked for mutations in 25 coding repeats contained in eight genes already known to be mutated in these cancers or in 17 other genes with an expected role in carcinoge...
