Disease relevance of Aneuploidy

  • The Rpa1 mutation resulted in defects in DNA double-strand break repair and precipitated chromosomal breaks as well as aneuploidy in primary heterozygous mutant mouse embryonic fibroblasts [1].
  • Eight of the nine specimens of infiltrating ductal carcinoma that contained high levels of LIP were negative for estrogen receptor and progesterone receptor (ER-/PR-); all nine tumors were aneuploid and poorly differentiated, and eight of nine were highly proliferative [2].
  • However, the DNA histograms of cells in hyperbasophilic (intensely toluidine blue-positive) foci were aneuploid (2C-18C) and resembled those of cells in hepatocellular carcinomas (2C-23C) [3].
  • BACKGROUND & AIMS: Expression of the mucin-associated carbohydrate antigen sialyl-Tn (STn) and DNA aneuploidy has each been shown to correlate with malignant transformation in patients with sporadic colon cancer and in those with ulcerative colitis (UC) [4].
  • Although SMAD4 mutations have been associated with late-stage or metastatic disease, our combined molecular and cytogenetic data best fit a model in which SMAD4 mutations occur before colorectal cancers become aneuploid/polyploid, but after the MSI(+) and MSI(-) pathways diverge [5].
 

Psychiatry related information on Aneuploidy

 

High impact information on Aneuploidy

  • Plk4+/- embryonic fibroblasts had increased centrosomal amplification, multipolar spindle formation and aneuploidy compared with wild-type cells [8].
  • Constitutional aneuploidy and cancer predisposition caused by biallelic mutations in BUB1B [9].
  • We identified a common genetic variant in STK15 (resulting in the amino acid substitution F31I) that is preferentially amplified and associated with the degree of aneuploidy in human colon tumors [10].
  • Meiotic arrest and aneuploidy in MLH3-deficient mice [11].
  • We have previously shown in small numbers of patients that disruption of TP53 and CDKN2A typically occurs before aneuploidy and cancer [12].

Associations of Aneuploidy with chemical compounds

  • Relating the level of cathepsin D to other prognostic factors in the patients with node-negative disease, we found an association with aneuploidy but none with estrogen or progesterone receptors, tumor size, or the age of the patient [28].
  • (i) Random aneuploidy was detected before transformation in up to 90% of CH embryo cells treated with the carcinogen nitrosomethylurea (NMU) [29].
  • Avicins, a family of triterpenoid saponins from Acacia victoriae (Bentham), suppress H-ras mutations and aneuploidy in a murine skin carcinogenesis model [30].
  • Sperm nuclei from eight normal, healthy donors were hybridized in situ with the biotin-labeled Y-specific pHY2.1 DNA probe to evaluate the X:Y ratio, the location of the Y chromosome, and the frequency of Y aneuploidy in human sperm [31].
  • Expression of BubR1Delta579Delta610 augmented the mitotic delay induced by spindle disruption in transfected cells as well as in clones engineered to inducibly express the mutant protein upon exposure to doxycycline and ultimately led to increased aneuploidy [32].
 

Gene context of Aneuploidy

  • Furthermore, although BubR1 hypomorphic mice have less aneuploidy than Bub3/Rae1 haploinsufficient mice, they age much faster [33].
  • Thus, both increased and decreased NDC1 dosage can lead to aneuploidy [34].
  • The mitotic spindle checkpoint protein Bub1 has been found to be mutated at low frequency in certain human cancers characterized by aneuploidy [35].
  • The MPC, detected on the basis of bright CD38 expression (CD38+2), demonstrated DNA aneuploidy in 65% of cases (DNA index range of 0.9 to 1.3) [36].
  • These experiments reveal an important new functional assay regulated by the BRCA1-dependent ubiquitin ligase, and the results suggest that the loss of this BRCA1 activity could cause the centrosome hypertrophy and subsequent aneuploidy typically found in breast cancers [37].
