Sex chromosomes and micronuclei in human lymphocytes.

open access: yes, 1996
The objectives of this study were to determine in humans the relationship between sex chromosome loss and increased micronucleus frequencies with age, the establishment of sex chromosome loss frequencies unbiased by cellular survival factors, the ...

An Automated, Single Cell Quantitative Imaging Microscopy Approach to Assess Micronucleus Formation, Genotoxicity and Chromosome Instability

open access: yesCells, 2020
Micronuclei are small, extranuclear bodies that are distinct from the primary cell nucleus. Micronucleus formation is an aberrant event that suggests a history of genotoxic stress or chromosome mis-segregation events.

Micronuclei images and quantification.

open access: yes, 2018
FSS exposure results in an increase in CREST-positive micronuclei. Micronuclei were observed in all cell populations and quantified on multiple slides using CREST (green) and DAPI (red) staining for control and adherent cell populations (after three ...

MITF maintains genome stability in nonmelanocyte lineages

open access: yesMolecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

The effects of sex, age and cigarette smoking on micronucleus and degenerative nuclear alteration frequencies in human buccal cells of healthy Bosnian subjects

open access: yesJournal of Health Sciences, 2013
Introduction: This study was performed to establish a baseline value of micronucleus frequency in buccal cells and to estimate the impact of the most common factors (sex and age, and smoking) on micronucleus and degenerative nuclear alteration ...

Chromothripsis from DNA damage in micronuclei [PDF]

open access: yesNature, 2015
Genome sequencing has uncovered a new mutational phenomenon in cancer and congenital disorders called chromothripsis. Chromothripsis is characterized by extensive genomic rearrangements and an oscillating pattern of DNA copy number levels, all curiously restricted to one or a few chromosomes.

Translating whole‐genome doubling into precision medicine in cancer

open access: yesMolecular Oncology, EarlyView.
Whole‐genome doubling creates a WGD‐positive tumor state characterized by persistent chromosomal instability, karyotypic diversification, and cellular stress. These same biological pressures drive aggressive tumor evolution while exposing therapeutic vulnerabilities, providing a rationale for WGD‐informed precision medicine. Whole‐genome doubling (WGD)

PARG silencing decreased BaP-induced micronuclei formation.

open access: yes, 2016
Representative photo micrographs were shown as following: A, Normal mononucleated (m), binucleated (b), andtrinucleated (t) cells without micronuclei (100×). B, Binucleated cell without micronuclei (1000×). C, Multiple micronuclei (arrows) in binucleated

DNA content, repeatome composition and origin of the Zea mays micronuclei

open access: yesScientific Reports
Micronuclei originate from DNA damage generated by clastogenic and/or by aneugenic effects. Depending on the pattern of damage, they may have distinct genomic origin and composition.
