The tolerance of aneuploidy in yeast

open access: yesGenetical Research, 1970
SUMMARYSingle ascospore cultures from triploids were screened as a potential source of disomic tester stocks for the purpose of genetical mapping of chromosomes in yeast. A high tolerance of aneuploidy was found, and strains disomic for only one chromosome were rare.

DNA methylation and copy number alterations in the progression of HPV-associated high-grade vulvar intraepithelial lesion. [PDF]

open access: yesInt J Cancer
What's new? Patients with human papillomavirus (HPV)‐associated high‐grade vulvar intraepithelial lesion (HSIL) often undergo damaging treatments to prevent progression to cancer. Molecular characterization of HSIL to assess progression risk could reduce the need for aggressive interventions. Here, cancer risk stratification of HSIL was investigated by

Stem-Like Adaptive Aneuploidy and Cancer Quasispecies [PDF]

open access: yesarXiv, 2013
We analyze and reinterpret experimental evidence from the literature to argue for an ability of tumor cells to self-regulate their aneuploidy rate. We conjecture that this ability is mediated by a diversification factor that exploits molecular mechanisms common to embryo stem cells and, to a lesser extent, adult stem cells, that is eventually ...

Distinct clinicopathological characteristics, genomic alteration and prognosis in breast cancer with concurrent TP53 mutation and MYC amplification

open access: yesThoracic Cancer, Volume 13, Issue 24, Page 3441-3450, December 2022., 2022
Breast cancer with concurrent TP53 mutation and MYC amplification demonstrated higher grade and stage, more positive HER2 status, higher Ki67 levels, and more mutations in genes involved in ERBB and TGF‐β signaling pathways, as well as exclusive FANCG/CDKN2B/QKI copy number amplifications.

Machine-learning analysis reveals an important role for negative selection in shaping cancer aneuploidy landscapes

open access: yesGenome Biology
Background Aneuploidy, an abnormal number of chromosomes within a cell, is a hallmark of cancer. Patterns of aneuploidy differ across cancers, yet are similar in cancers affecting closely related tissues.

Serine-Dependent Sphingolipid Synthesis Is a Metabolic Liability of Aneuploid Cells

open access: yesCell Reports, 2017
Aneuploidy disrupts cellular homeostasis. However, the molecular mechanisms underlying the physiological responses and adaptation to aneuploidy are not well understood.

The Heterotaxy Gene CCDC11 Is Important for Cytokinesis via RhoA Regulation

open access: yesCytoskeleton, EarlyView.
ABSTRACT Mutations in CCDC11 (cfap53) have been identified in multiple patients with heterotaxy (Htx), a disorder of left–right (LR) patterning of the internal organs. In Xenopus, depletion of Ccdc11 causes defects in LR patterning, recapitulating the patient phenotype. Upon Ccdc11 depletion, monociliated cells of the Left–Right Organizer (LRO) exhibit

Chinese expert consensus on the diagnosis and treatment of HER2‐altered non–small cell lung cancer

open access: yesThoracic Cancer, Volume 14, Issue 1, Page 91-104, January 2023., 2023
To improve the diagnosis and treatment of HER2‐altered non‐small cell lung cancer in China, we reached consensus on detection strategy based on alteration type, sample selection, detection method, quality control, and treatment suggestion. Moreover, we systematically reviewed the clinical efficacy, resistance mechanisms, and development status of HER2‐

Clinical and molecular correlates of tumor aneuploidy in metastatic non-small cell lung cancer

open access: yesScientific Reports
Recent studies have linked elevated tumor aneuploidy to anti-tumor immune suppression and adverse survival following immunotherapy. Herein, we provide supportive evidence for tumor aneuploidy as a biomarker of response to immunotherapy in patients with ...

Deep Learning Models Delineates Multiple Nuclear Phenotypes in H&E Stained Histology Sections [PDF]

open access: yesarXiv, 2018
Nuclear segmentation is an important step for profiling aberrant regions of histology sections. However, segmentation is a complex problem as a result of variations in nuclear geometry (e.g., size, shape), nuclear type (e.g., epithelial, fibroblast), and nuclear phenotypes (e.g., vesicular, aneuploidy). The problem is further complicated as a result of
