Excessive centrosome abnormalities without ongoing numerical chromosome instability in a Burkitt's lymphoma

open access: yesMolecular Cancer, 2003
Numerical and structural centrosome abnormalities are detected in various human malignancies and have been implicated in the formation of multipolar mitoses, chromosome missegregation, and chromosomal instability.

High-grade serous ovarian carcinoma organoids as models of chromosomal instability

open access: yeseLife, 2023
High-grade serous ovarian carcinoma (HGSOC) is the most genomically complex cancer, characterized by ubiquitous TP53 mutation, profound chromosomal instability, and heterogeneity.

PIGN spatiotemporally regulates the spindle assembly checkpoint proteins in leukemia transformation and progression

open access: yesScientific Reports, 2021
Phosphatidylinositol glycan anchor biosynthesis class N (PIGN) has been linked to the suppression of chromosomal instability. The spindle assembly checkpoint complex is responsible for proper chromosome segregation during mitosis to prevent chromosomal ...

Chromosomal Instability Is Associated with Higher Expression of Genes Implicated in Epithelial-Mesenchymal Transition, Cancer Invasiveness, and Metastasis and with Lower Expression of Genes Involved in Cell Cycle Checkpoints, DNA Repair, and Chromatin Maintenance

open access: yesNeoplasia: An International Journal for Oncology Research, 2008
Chromosomal instability—a hallmark of epithelial cancers—is an ongoing process that results in aneuploidy and karyotypic heterogeneity of a cancer cell population.

Epigenetic Instability and Chromosomal Instability in Hepatocellular Carcinoma [PDF]

open access: yesThe American Journal of Pathology, 2006
The aim of this study was to clarify the association between the epigenetic instability phenotype and the chromosomal instability phenotype in primary hepatocellular carcinoma (HCC). Sixty primary HCC tumors were examined. Methylation status for nine CpG islands (the p16, COX2, GSTP1, RASSF1A, E-cadherin, and APC gene promoters, and the MINT 1, 25, and

In silico pathway analysis based on chromosomal instability in breast cancer patients

open access: yesBMC Medical Genomics, 2020
Background Complex genomic changes that arise in tumors are a consequence of chromosomal instability. In tumor cells genomic aberrations disrupt core signaling pathways involving various genes, thus delineating of signaling pathways can help understand ...

Studying chromosome instability in the mouse [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - Reviews on Cancer, 2008
Aneuploidy has long been recognized as one of the hallmarks of cancer. It nonetheless remains uncertain whether aneuploidy occurring early in the development of a cancer is a primary cause of oncogenic transformation, or whether it is an epiphenomenon that arises from a general breakdown in cell cycle control late in tumorigenesis.

A CINful way to overcome addiction: how chromosomal instability enables cancer to overcome its oncogene addiction

open access: yesEMBO Molecular Medicine, 2020
Oncogene‐addicted tumors present a valuable target for therapeutic intervention and an opportunity to achieve a wide therapeutic window. Nonetheless, resistance to targeted therapies is frequently observed and it arises through multiple mechanisms ...

Causes of Chromosomal Instability

open access: yes, 2015
The majority of human cancer cells are highly aneuploid harboring chromosome numbers deviating from the modal number of 46. In cancer, aneuploidy is a consequence of an increased rate of whole chromosome missegregation during mitosis, a process known as chromosomal instability (CIN).

Chromosomal Instability in Gastric Cancer Biology

open access: yesNeoplasia: An International Journal for Oncology Research, 2017
Gastric cancer (GC) is the fifth most common cancer in the world and accounts for 7% of the total cancer incidence. The prognosis of GC is dismal in Western countries due to late diagnosis: approximately 70% of the patients die within 5 years following ...
