Introducción y objetivos: Una de las pocas especies de árboles adaptados a las condiciones ecológicamente limitantes del desierto de Atacama es Geoffroea decorticans, conocido como chañar. Es un valioso recurso multipropósito utilizado como alimento y producto medicinal. Sin embargo, aún no se han desarrollado marcadores de ADN codominantes específicos para esta especie que permitan realizar estudios genéticos en la especie. El objetivo del presente trabajo fue desarrollar y validar marcadores microsatélites (SSR) para G. decorticans, con el fin de analizar en el futuro su diversidad genética y estructura genética poblacional. M&M: Se buscaron marcadores SSR en el genoma de G. decorticans a partir del método Next-Generation Sequencing (NGS), y se validaron a través de treinta individuos distribuidos en diferentes localidades del norte de Chile. Resultados: Se identificó un total de ~144.117 loci de microsatélites y de ellos se usó un grupo de 41 pares de cebadores para la validación. Los fragmentos amplificados variaron de 106 pb a 225 pb, el número de alelos varió de 2 a 9, y el valor PIC de los 41 loci SSR osciló entre 0,32 y 0,86, con un promedio de 0,64. Conclusiones: Por primera vez se desarrollaron marcadores SSR putativamente neutros específicos de la especie G. decorticans con el fin de promover estudios genéticos para la conservación de la especie. El presente estudio provee 38 nuevos marcadores SSR polimórficos, los cuales podrían servir como una herramienta efectiva para estimar la diversidad genética, estructura genética y para ser empleados en programas de mejora.

Background: Numerous sequencing techniques have been progressed since the 1960s with the rapid development of molecular biology studies focusing on DNA and RNA. Methods: a great number of articles, book chapters, websites are reviewed, and the studies covering NGS history, technology and applications to cancer therapy are included in the present article. Results: High throughput next-generation sequencing (NGS) technologies offer many advantages over classical Sanger sequencing with decreasing cost per base and increasing sequencing efficiency. NGS technologies are combined with bioinformatics software to sequence genomes to be used in diagnostics, transcriptomics, epidemiologic and clinical trials in biomedical sciences. The NGS technology has also been successfully used in drug discovery for the treatment of different cancer types. Conclusion: This review focuses on current and potential applications of NGS in various stages of drug discovery process, from target identification through to personalized medicine.

Introduction To evaluate a next-generation sequencing (NGS) workflow in the screening and diagnosis of thalassemia. Methods In this prospective study, blood samples were obtained from people undergoing genetic screening for thalassemia at our centre in Guangzhou, China. Genomic DNA was polymerase chain reaction (PCR)-amplified and sequenced using the Ion Torrent system and results compared with traditional genetic analyses. Results Of the 359 subjects, 148 (41%) were confirmed to have thalassemia. Variant detection identified 35 different types including the most common. Identification of the mutational sites by NGS were consistent with those identified by Sanger sequencing and Gap-PCR. The sensitivity and specificities of the Ion Torrent NGS were 100%. In a separate test of 16 samples, results were consistent when repeated ten times. Conclusion Our NGS workflow based on the Ion Torrent sequencer was successful in the detection of large deletions and non-deletional defects in thalassemia with high accuracy and repeatability.

(1) Background: Human papillomaviruses (HPVs) are known to be related to the development of about 5% of all human cancers. The clinical relevance of HPV infection has been deeply investigated in carcinomas of the oropharyngeal area, uterine cervix, and anogenital area. To date, several different methods have been used for detecting HPV infection. The aim of the present study was to compare three different methods for the diagnosis of the presence of the HPV genome. (2) Methods: A total of 50 samples were analyzed. Twenty-five of them were tested using both next generation sequencing (NGS) and VisionArray® technology, the other 25 were tested using Hybrid Capture (HC) II assay and VisionArray® technology. (3) Results: A substantial agreement was obtained using NGS and VisionArray® (κ = 0.802), as well as between HC II and VisionArray® (κ = 0.606). In both analyses, the concordance increased if only high risk HPVs I(HR-HPVs) were considered as “positive”. (4) Conclusions: Our data highlighted the importance of technical choice in HPV characterization, which should be guided by the clinical aims, costs, starting material, and turnaround time for results.
