Prevalence of chromosome anomalies in a deer farm with fertility decline in Malaysia

Future Science OA, 2020
Background: A number of factors are known to reduce fertility rate in animals and one of the important categories of such factors is chromosome anomalies. They can occur with or without causing phenotypic abnormalities on animals; in some cases, they may

Chromosome Banding and Mechanism of Chromosome Aberrations

, 2021
Chromosome identification depends on the morphological features of the chromosome and therefore karyotype and its banding pattern analyses are the most suitable technique to identify each and every chromosome of a chromosome complement. Moreover, aberrations caused by breaks play an important role in the evolution of a chromosome set and chromosome ...

A large‐scale retrospective study in metastatic breast cancer patients using circulating tumour DNA and machine learning to predict treatment outcome and progression‐free survival

Molecular Oncology, EarlyView.
There is an unmet need in metastatic breast cancer patients to monitor therapy response in real time. In this study, we show how a noninvasive and affordable strategy based on sequencing of plasma samples with longitudinal tracking of tumour fraction paired with a statistical model provides valuable information on treatment response in advance of the ...

Clonal chromosomal and genomic instability during human multipotent mesenchymal stromal cells long-term culture. [PDF]

PLoS ONE, 2018
Spontaneous mutagenesis often leads to appearance of genetic changes in cells. Although human multipotent mesenchymal stromal cells (hMSC) are considered as genetically stable, there is a risk of genomic and structural chromosome instability and ...

Multi‐omic characterization of consensus molecular subtype 1 (CMS1) colorectal cancer with dampened immune response improves precision medicine

Molecular Oncology, EarlyView.
This study highlights the importance of multi‐omic analyses in characterizing colorectal cancers. Indeed, our analysis revealed a rare CMS1 exhibiting dampened immune activation, including reduced PD‐1 expression, moderate CD8+ T‐cell infiltration, and suppressed JAK/STAT pathway.

COMPARISON BETWEEN TWO FISH TECHNIQUES IN THE IN VITRO STUDY OF CYTOGENETIC MARKERS FOR LOW-DOSE X-RAY EXPOSURE IN HUMAN PRIMARY FIBROBLASTS

Frontiers in Genetics, 2013
This work is about the setup of an in vitro system to report low-dose of X-rays as measured as cytogenetic damage. Q- and m-FISH, for telomere length and chromosome instability analysis respectively, were compared to evaluate their sensitivity in the low-

m-FISH analysis reveals complexity of chromosome aberrations in individuals occupationally exposed with internal plutonium: A pilot study to assess the relevance of complex aberrations as biomarkers of exposure to high-LET α particles [PDF]

, 2005
We recently demonstrated that a significant proportion of apparently stable insertions induced after exposure to a mean of 1 α particle/cell, detected using 3-colour FISH, were part of larger unstable complexes when visualised by 24-colour FISH ...
