Aneuploidy, loss or gain of whole chromosomes, is a prominent feature of carcinomas, and is generally considered to play an important role in the initiation and progression of cancer.

Aneuploidy is a characteristic of cancer, with greater than 90% of all solid tumors in humans carrying an aberrant karyotype. Yet, whether or how this condition contributes to tumorigenesis is not understood. Here we summarize our recent findings on the effects of aneuploidy on cell physiology and proliferation. 2019-09-23 · Aneuploidy.

En cancersjukdom går igenom flera olika faser. Vanligtvis tar det länge innan cancern börjar utvecklas Tumor-stroma interactions in colon cancer.

Aneuploidy, an aberrant chromosome number, has been recognized as a common characteristic of cancer cells for more than 100 years and has been suggested as a cause of tumorigenesis for nearly as long. However, this proposal had remained untested due to the difficulty of selectively generating aneuploidy without causing other damage.

Aneuploidy, defined as chromosome gains and losses, is a hallmark of cancer. However, compared with other tumor types, extensive aneuploidy is relatively rare in prostate cancer. Thus, whether numerical chromosome aberrations dictate disease progression in prostate cancer patients is not known.

Glioblastoma is an aggressive cancer of the brain. It is a very fast-growing cancer that spreads quickly. Glioblastoma is the most common type of malignant brain tumor in adults.

… 2018-05-10 · Interestingly, a complex relationship between aneuploidy and cancer has also been revealed, proposing that aneuploidy can either promote or inhibit cancer progression depending on the evolutionary context. This has led to the paradox of aneuploidy in cancer [45, 46]. There have been attitude changes towards the study of aneuploidy as well. Aneuploidy is the presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46. It does not include a difference of one or more complete sets of chromosomes. 2006-12-01 · Aneuploidy has been recognized as a common characteristic of cancer cells for >100 years.

Here we summarize our recent findings on the effects of aneuploidy on cell physiology and proliferation. Here we mapped the aneuploidy landscapes of about 1,000 human cancer cell lines, and analysed genetic and chemical perturbation screens 2-9 to identify cellular vulnerabilities associated with aneuploidy.

Germline mutations in the mitotic checkpoint component BUBR1 and the centrosomal protein CEP57 have been identified in MVA patients, providing strong evidence that mitotic checkpoint defects can cause aneuploidy in humans [ 15 , 16 , 17 ]. 2019-07-02 · Background DNA aneuploidy has attracted growing interest in clinical practice. Nevertheless, its prognostic value in gastric cancer patients remains controversial. This meta-analysis aims to explore the impact of DNA ploidy status on the survival of gastric cancer patients.

Aneuploidy can lead to fatal conditions during development, and to cancer in an adult organism. A safety mechanism may exist that helps the body to detect and remove these cells. Yet, exactly this happens is still poorly understood: in particular, it is unclear how cells manage to ‘count’ their chromosomes.

Cancer is driven by multiple types of genetic alterations, which range in size from point mutations to whole-chromosome gains and losses, known as aneuploidy.

However, this proposal had remained untested due to the difficulty of selectively generating aneuploidy without causing other damage. Aneuploidy, defined as chromosome gains and losses, is a hallmark of cancer. However, compared with other tumor types, extensive aneuploidy is relatively rare in prostate cancer. Thus, whether numerical chromosome aberrations dictate disease progression in prostate cancer patients is not known. There is evidence that aneuploidy makes cancer cells more aggressive, but it has been difficult to definitively demonstrate that link because in most types of cancer nearly all tumors are aneuploid, making it difficult to perform comparisons. Analyzing >10,000 human cancers, Taylor et al. show that aneuploidy is correlated with somatic mutation rate, expression of proliferation genes, and decreased leukocyte infiltration.
