Identifying Mazama gouazoubira (Artiodactyla; Cervidae) chromosomes involved in rearrangements induced by doxorubicin

Genetics and Molecular Biology, 2017
The process of karyotype evolution in Cervidae from a common ancestor (2n = 70, FN = 70) has been marked by complex chromosomal rearrangements. This ancestral karyotype has been retained by the current species Mazama gouazoubira (Fischer 1814), for which

Single-cell multiomics analysis reveals dynamic clonal evolution and targetable phenotypes in acute myeloid leukemia with complex karyotype

Nature Genetics
Chromosomal instability is a major driver of intratumoral heterogeneity (ITH), promoting tumor progression. In the present study, we combined structural variant discovery and nucleosome occupancy profiling with transcriptomic and immunophenotypic changes

Phase‐Separation of YAP Mediates AJUBA Super Enhancer Activation to Promote Aberrant Mitosis in Breast Cancer

Advanced Science, EarlyView.
YAP undergoes phase separation to activate the AJUBA super‐enhancer, driving aberrant mitosis through spindle checkpoint dysregulation in breast cancer. This study uncovers a mechanistic link between YAP condensates, super‐enhancer activation, and aneuploidy formation.

FLT3 Length Mutations as Marker for Follow-Up Studies in Acute Myeloid Leukaemia [PDF]

, 2004
Length mutations within the FLT3 gene (FLT3-LM) can be found in 23% of acute myeloid leukaemia (AML) and thus are the most frequent mutations in AML. FLT3-LM are highly correlated with AML with normal karyotype and other cytogenetic aberrations of the ...

Karyotypic evolution in a human mucoepidermoid carcinoma [PDF]

Hereditas, 2008
Chromosomes were studied in cultured material from two different areas of a human mucoepidermoid carcinoma. The detailed banding analyses showed no less than 41 different karyotypes. Comparisons between these revealed (1) that the tumour probably had originated with a normal, diploid stemline; (2) that the progression had mainly proceeded by steps in a

Depletion of Sorcs3 Activates Totipotency in Mouse Embryonic Stem Cells by Modulating Key Signaling Pathways

Advanced Science, EarlyView.
In this article, Shuai and colleagues found that depletion of Sorcs3 could activate totipotency in mESCs, promising bidirectional differentiation potential to embryonic and extraembryonic lineages. The underlying mechanism might be activation of Tfap2c and repression of TGF‐β, PI3K‐AKT, and lysosome pathways.

Further insights on chromosomal evolution of the genus Enyalius with karyotype description of Enyalius boulengeri Etheridge, 1969 (Squamata, Leiosauridae)

Caryologia, 2021
The genus Enyalius is composed of 10 described species inhabiting forest areas in Amozônia, Cerrado and Atlantic forest biomes. Currently, eight species with high levels of chromosome variation have been karyotyped.

PARPi Combining Nanoparticle LIN28B siRNA for the Management of Malignant Ascites

Advanced Science, EarlyView.
This study demonstrates that co‐inhibition of LIN28B and PARP using siLin28b/DSSP@lip‐PEG‐FA nanoparticles in combination with the PARP inhibitor BMN673 effectively suppresses the accumulation of malignant ascites associated with advanced cancers.

Why Do Some Vertebrates Have Microchromosomes?

Cells, 2021
With more than 70,000 living species, vertebrates have a huge impact on the field of biology and research, including karyotype evolution. One prominent aspect of many vertebrate karyotypes is the enigmatic occurrence of tiny and often cytogenetically ...
