Introduction: The very aggressive soft tissue and bone pediatric tumor Ewing’s sarcoma (ES) is caused in most cases by the chromosomal translocation t(11;22)(q24;q12), which encodes an aberrant chimeric transcription factor (EWS-FLI1) that regulates target genes, including the critical on...
BACKGROUND: We developed simple sequence repeats (SSR) for Eremanthus erythropappus (DC.) MacLeish, an endangered tree species endemic to the Brazilian Savanna and Atlantic Forest biomes, and tested their transferability to two closely related Eremanthus species. RESULTS: Using a genomic library enriche...

Fourteen novel microsatellite loci are described and characterized in two species of electric eels, Electrophorus variiand E. voltaifrom floodplains and rivers of the Amazon rainforest. These loci are polymorphic, highly informative, and have the capacity to detect reliable levels of genetic diversity. L...
The Neotropical catfish species Ageneiosus pardalis, Pimelodus grosskopfii, and Sorubim cuspicaudus are important fishery resources in Colombia that show historical declines in their capture. This study used next-generation sequencing with 454 FLX technology (Roche Applied Science) and bioinformatics ana...

BACKGROUND: Polymorphic microsatellite markers were developed for Gaultheria pumila (Ericaceae) to evaluate genetic diversity and population structure within its native range in Chile. This is a very important Ericaceae endemic to Chile with a large commercial potential. Its resistance to different abiot...
Background: Pearl oyster Pinctada fucata martensii is cultured for producing round nucleated pearls. Pearl production involves a surgical operation where a mantle tissue graft from a donor oyster and a round nucleus are implanted in the gonad of a host oyster. Whether the mantle graft implanted in the go...
Background: Memecylon species are commonly used in Indian ethnomedical practices. The accurate identification is vital to enhance the drug's efficacy and biosafety. In the present study, PCR based techniques like RAPD, ISSR and DNA barcoding regions, such as 5s, psbA-trnH, rpoC1, ndh and atpF-atpH, were ...
Las secuencias repetidas en tándem, específicamente los mini y micro satélites, han demostrado ser muy eficaces en la clasificación de bacterias patogénicas como B. anthracis, M. tuberculosis y P. aeruginosa, entre otras. En humanos es manifiesta su participación estando relacionados con más de oc...
Piabanha (Brycon insignis) is a freshwater fish species from the drainages in Southeastern Brazil. During the 1950s, it was an important economic and food resource for local populations, but dramatic and continuous environmental degradation seriously jeopardized the B. insignis populations in the region....
Small amounts of DNA circulate in both healthy and diseased human plasma/serum, and increased concentrations of DNA are present in the plasma of cancer patients. Characteristics of tumor DNA have been found in genetic material extracted from the plasma of cancer patients. These features include decreased...
