Omics tools applied to the study of chagas disease vectors: Cytogenomics and genomics
(2021-06-01)
Chagas disease is an illness caused by the protozoan Trypanosoma cruzi that is distributed in 21 countries of Latin America. The main way of transmission of T. cruzi is through the feces of triatomines infected with the ...
B chromosomes: from cytogenetics to systems biology
(2017-02-01)
Though hundreds to thousands of reports have described the distribution of B chromosomes among diverse eukaryote groups, a comprehensive theory of their biological role has not yet clearly emerged. B chromosomes are ...
Cytogenomic Delineation and Clinical Follow-up of Two Siblings with an 8.5 Mb 6q24.2-q25.2 Deletion Inherited From a Paternal Insertion
(Wiley-Blackwell, 2014-09-01)
The chromosomal segment 6q24-q25 comprises a contiguous gene microdeletion syndrome characterized by intrauterine growth retardation, growth delay, intellectual disability, cardiac anomalies, and a dysmorphic facial ...
The b chromosomes of prochilodus lineatus (Teleostei, characiformes) are highly enriched in satellite dnas
(2021-06-01)
B or supernumerary chromosomes are dispensable elements that are widely present in numerous eukaryotes. Due to their non-recombining nature, there is an evident tendency for repetitive DNA accumulation in these elements. ...
The repetitive DNA element BncDNA, enriched in the B chromosome of the cichlid fish Astatotilapia latifasciata, transcribes a potentially noncoding RNA
(Springer, 2017-03-01)
Supernumerary chromosomes have been studied in many species of eukaryotes, including the cichlid fish, Astatotilapia latifasciata. However, there are many unanswered questions about the maintenance, inheritance, and ...
Trisomy 1q32 and monosomy 11q25 associated with congenital heart defect: cytogenomic delineation and patient fourteen years follow-up
(2014-08-22)
Abstract
Background
Partial duplication 1q is a rare cytogenetic anomaly frequently associated to deletion of another chromosome, making it difficult to define the precise ...
DNA transposon invasion and microsatellite accumulation guide W chromosome differentiation in a Neotropical fish genome
(Springer, 2019-12-01)
Sex chromosome differentiation is subject to independent evolutionary processes among different lineages. The accumulation of repetitive DNAs and consequent crossing-over restriction guide the origin of the heteromorphic ...
