Project description:Next-Generation-Sequencing (NGS) technologies have led to important improvement in the detection of new or unrecognized infective agents, related to infectious diseases. In this context, NGS high-throughput technology can be used to achieve a comprehensive and unbiased sequencing of the nucleic acids present in a clinical sample (i.e. tissues). Metagenomic shotgun sequencing has emerged as powerful high-throughput approaches to analyze and survey microbial composition in the field of infectious diseases. By directly sequencing millions of nucleic acid molecules in a sample and matching the sequences to those available in databases, pathogens of an infectious disease can be inferred. Despite the large amount of metagenomic shotgun data produced, there is a lack of a comprehensive and easy-use pipeline for data analysis that avoid annoying and complicated bioinformatics steps. Here we present HOME-BIO, a modular and exhaustive pipeline for analysis of biological entity estimation, specific designed for shotgun sequenced clinical samples. HOME-BIO analysis provides comprehensive taxonomy classification by querying different source database and carry out main steps in metagenomic investigation. HOME-BIO is a powerful tool in the hand of biologist without computational experience, which are focused on metagenomic analysis. Its easy-to-use intrinsic characteristic allows users to simply import raw sequenced reads file and obtain taxonomy profile of their samples.
Project description:26 breast cancer patient serum EV derived RNA and 4 control serum EV derived RNA was sequenced to explore the diagnostic potential of EV. EV RNA was isolated by EXOQUICK® Exosome isolation and RNA purification kit for serum/plasma (System Biosciences,CA) and was reverse transcribed to make amplified cDNA by SMART seq v4 ultra-low input RNA kit (Takara Bio Inc, USA). A sequencing library was made using 1 ng of sheared cDNA using The Low Input Library Prep Kit v2 (Takara Bio Inc, USA). DNA unique Dual index kit was used to combine libraries for sequencing (Takara Bio Inc, USA). NOVASEQ 6000 was used for sequencing to generate 25 million paired end reads per sample.
