Cytogenetic techniques in current biomedical research. Part II: chromosomal rearrangements

Фундаментальная и клиническая медицина, 2022
Mutations represent a natural mechanism for adaptation of species to changing environmental conditions. Chromosomal rearrangements play a pivotal role in the evolution, as evidenced by the comparison of human and non-human primate karyotypes, and have ...

Clonal karyotype evolution involving ring chromosome 1 with myelodysplastic syndrome subtype RAEB-t progressing into acute leukemia [PDF]

, 2006
s Karyotypic evolution is a well-known phenomenon in patients with malignant hernatological disorders during disease progression. We describe a 50-year-old male patient who had originally presented with pancytopenia in October 1992.

Lnc‐HZ05 Suppresses Trophoblast Cell Migrasome Formation by Disrupting TGFβ2 Pathway in Unexplained Recurrent Miscarriage

Advanced Science, EarlyView.
TGFβ2 signaling‐mediated migration/invasion and migrasome formation are suppressed in recurrent miscarriage (RM) versus healthy control villous tissues and are negatively associated with unexplained RM. In mechanism, TGFβ2 promotes trophoblast cell migration/invasion and migrasome formation, all of which are suppressed by lnc‐HZ05. In details, lnc‐HZ05

Karyotypes of three species of marine catfishes from Brazil

Brazilian Journal of Oceanography, 1994
The chromosomes of three species of fishes belonging to the family Ariidae -Netuma barba, Genidens genidens and Amis parkeri - were studied after conventional Giemsa staining. All three species have a diploid chromosome number of 2n = 56.

Cytogenetic techniques in current biomedical research. PART III: numerical alterations of human karyotype

Фундаментальная и клиническая медицина, 2022
Numerical abnormalities of karyotype are the result of genome mutations. Unlike gene and chromosomal abnormalities, genome mutations do not disrupt the structure of DNA or chromosomes. The cause of numerical changes in the karyotype is a violation of the

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.

Pneumocystis carinii karyotypes [PDF]

Journal of Clinical Microbiology, 1990
Pulsed-field gel electrophoresis techniques were used to examine the chromosomes of Pneumocystis carinii isolated from laboratory rats and two human subjects. P. carinii organisms isolated from each of four rat colonies and from two patients each produced a distinct band pattern, but in all cases the bands ranged in size from 300 to 700 kilobase pairs.

A Set of Novel Venom Proteins Enables Parasitoid Wasps to Exploit Older Hosts and Coexist with Competitors

Advanced Science, EarlyView.
This study elucidates a molecular mechanism enabling species coexistence between parasitoid wasps, showing how Asobara japonica uses a set of novel venom proteins to delay host development and exploit older hosts, thereby achieving temporal niche partitioning with Leptopilina drosophilae. Abstract Interspecific competition can drive species coexistence

Apomixis for no bacteria-induced thelytoky in Diglyphus wani (Hymenoptera: Eulophidae)

Frontiers in Genetics, 2023
In Hymenoptera species, the reproductive mode is usually arrhenotoky, where haploid males arise from unfertilized eggs and diploid females from fertilized eggs.

Measured parental height in Turner syndrome—a valuable but underused diagnostic tool [PDF]

, 2017
Early diagnosis of Turner syndrome (TS) is necessary to facilitate appropriate management, including growth promotion. Not all girls with TS have overt short stature, and comparison with parental height (Ht) is needed for appropriate evaluation.
