WebNov 1, 2024 · Chromosome instability (CIN) is an abnormal phenotype, characterized by progressive numerical and/or structural chromosomal changes, which is observed in virtually all cancer types. CIN generates intratumoral heterogeneity, drives cancer development, and promotes metastatic progression, and thus, it is associated with highly aggressive, drug ... WebMay 19, 2024 · Chromosome instability (CIN) has been repeatedly associated with aging and progeroid phenotypes. Moreover, brain-specific CIN seems to be an important element of pathogenic cascades leading to neurodegeneration in late adulthood. Alternatively, CIN and aneuploidy (chromosomal loss/gain) syndromes exhibit accelerated aging …

In colorectal cancers, this instability is most often due to chromosomal … WebChromosomal instability (CIN) is one of the hallmarks of cancer that can lead to abnormal chromosome number (aneuploidy) and structure. Chromosomal instability is defined as the gain or loss of chromosome(s) during mitosis ( Lengauer, Kinzler, & Vogelstein, 1998 ; McGranahan, Burrell, Endesfelder, Novelli, & Swanton, 2012 ).
WebFeb 16, 2024 · Chromosomal instability (CIN) is an important marker of cancer, which is closely related to tumorigenesis, disease progression, treatment efficacy, and patient prognosis. However, due to the limitations of the currently available detection methods, its exact clinical significance remains unknown. Previous studies have demonstrated that … WebChromosomal instability (CIN) is a pervasive feature of human cancers involved in tumor initiation and progression and which is found elevated in metastatic stages. CIN can provide survival and adaptation advantages to human cancers. However, too much of a good thing may come at a high cost for tumor cells as excessive degree of CIN-induced …
