genomic and epigenetic instability in colorectal cancer

abstract: colorectal cancer (crc) is the third most common cancer in men and the second most common cancer in women worldwide. both genetic and epigenetic alterations are common in crc and are the driving force of tumorigenesis. chromosomal instability, microsatellite instability and cpg island methylator phenotype pathways are responsible for genetic instability in colorectal cancer. chromosom...

p16INK4a Prevents Centrosome Dysfunction and Genomic Instability in Primary Cells

Aneuploidy, frequently observed in premalignant lesions, disrupts gene dosage and contributes to neoplastic progression. Theodor Boveri hypothesized nearly 100 years ago that aneuploidy was due to an increase in centrosome number (multipolar mitoses) and the resultant abnormal segregation of chromosomes. We performed immunocytochemistry, quantitative immunofluorescence, karyotypic analysis, and...

Loss of polycystin-1 causes centrosome amplification and genomic instability.

Autosomal dominant polycystic kidney disease (ADPKD) is the most common monogenetic disease predominantly caused by alteration or dysregulation of the PKD1 gene, which encodes polycystin-1 (PC1). The disease is characterized by the progressive expansion of bilateral fluid-filled renal cysts that ultimately lead to renal failure. Individual cysts, even within patients with germline mutations, ar...
