Meiosis and chromosome painting of sex chromosome systems in Ceboidea

American Journal of Primatology, 2001
AbstractThe identity of the chromosomes involved in the multiple sex system ofAlouatta caraya(Aca) and the possible distribution of this system among other Ceboidea were investigated by chromosome painting of mitotic cells from five species and by analysis of meiosis at pachytene in two species.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Assessment of Molecular Cytogenetic Methods for the Detection of Chromosomal Abnormalities [PDF]

, 2006
Some marker chromosomes and chromosome rearrangements are difficult to identify using G-bands by Giemsa staining after trypsin treatment (G-banding) alone.

Genomic restructuring in the Tasmanian devil facial tumour: chromosome painting and gene mapping provide clues to evolution of a transmissible tumour. [PDF]

PLoS Genetics, 2012
Devil facial tumour disease (DFTD) is a fatal, transmissible malignancy that threatens the world's largest marsupial carnivore, the Tasmanian devil, with extinction.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Characterization of two marker chromosomes in a patient with acute nonlymphocytic leukemia by two-color fluorescence in situ hybridization [PDF]

, 1993
A patient with acute nonlymphocytic leukemia (ANLL), M5b according to French-American-British (FAB) classification, showed monosomy 16, an extra 1p−, and a 21q+. These derivative chromosomes could not be defined by GTG-banding.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Chromosome painting in Arabidopsis thaliana [PDF]

The Plant Journal, 2001
Summary Chromosome painting, that is visualisation of chromosome segments or whole chromosomes based on fluorescence in situ hybridization (FISH) with chromosome‐specific DNA probes is widely used for chromosome studies in mammals, birds, reptiles and insects.

The evolution of the hypotetraploid Catolobus pendulus genome – the poorly known sister species of Capsella

Frontiers in Plant Science, 2023
The establishment of Arabidopsis as the most important plant model has also brought other crucifer species into the spotlight of comparative research. While the genus Capsella has become a prominent crucifer model system, its closest relative has been ...

Comparative Chromosome Painting in Carnivora and Pholidota [PDF]

Cytogenetic and Genome Research, 2012
The order of Carnivora has been very well characterized with over 50 species analyzed by chromosome painting and with painting probe sets made for 9 Carnivora species. Representatives of almost all families have been studied with few exceptions (Otariidae, Odobenidae, Nandiniidae, Prionodontidae).
