Silencing 22/50 of these genes, many of which are involved in DNA repair, caused cancer cell death, suggesting that these genes are …
WebFeb 6, 2024 · Chromosomal Instability is a mechanism to circumvent oncogene addiction. Genetic alterations driving resistance were most probably acquired during the course of the treatment. The most predominant genetic alteration in resistant tumors of a Kras-driven breast cancer mouse model was an amplification of the cMet oncogene. WebMay 15, 2011 · Chromosomal instability (CIN) is associated with poor prognosis in human cancer. However, in certain animal tumor models elevated CIN negatively impacts upon organism fitness, and is poorly tolerated by cancer cells.

Risk … WebChromosomal instability (CIN) is an emerging hallmark of cancer and its role in therapeutic responses has been increasingly attracting the attention of the research community. To target the vulnerability of tumors with high CIN, it is important to identify the genes and mechanisms involved in the maintenance of CIN. In our work, we recognize …
WebDec 3, 2024 · Abstract. Chromosomal instability (CIN) is the result of ongoing changes in the number (aneuploidy) and structure of chromosomes. CIN is induced by chromosome missegregation in mitosis and leads to karyotypic diversity within the cancer cell population, thereby adding to intratumor heterogeneity. Regardless of the overall pro-oncogenic …
