In 2015, we brought in many new features and improvements based on your requirements and feedback. We expanded the Strand NGS epigenomics toolkit by adding the MeDIP-Seq workflow in the v2.5 release. We also added new features like the alignment workflow and SV detection for split reads (watch the webinar), a browser-based copy number variation (CNV) view (watch the webinar), and correlation analysis. 2015 was also a year with some great publications that cited Avadis NGS and Strand NGS. Here is a small selection:
K-bZIP Mediated SUMO-2/3 Specific Modification on the KSHV Genome Negatively Regulates Lytic Gene Expression and Viral Reactivation (Wan-Shan Yang, et al.) published in PLoS Pathogens. The authors looked at ChIP-Seq data as well as RNA-Seq data to study the association of SUMO paralog genome modifications with KSHV (one of the seven known human oncoviruses) reactivation. Avadis NGS was used to align ChIP-Seq data to the KSHV genome build and to delineate the SUMO-1 and SUMO-2/3 binding patterns. RNA-Seq reads that did not align with hg19 were mapped with the KSHV genome in Avadis NGS and differential gene expression was determined based on sample wise transcript RPKM values reported by Avadis NGS and verified by RT-qPCR.
Novel roles for LIX1L in promoting cancer cell proliferation through ROS1-mediated LIX1L phosphorylation (Satoki Nakamura, et al.) published in Nature Scientific Reports. The authors report novel roles of Limb expression 1-like (LIX1L) in promoting cancer cell proliferation through ROS1- mediated LIX1L phosphorylation in oesophagus, gastric, breast, lung, thyroid, ovarian, kidney, liver, colon, prostate and pancreatic cancers. Strand NGS was used for alignment, filtering, quantification and statistical analysis of small RNA sequencing data, as well as prediction of miRNA targets.
Lysine-specific demethylase LSD2 suppresses lipid influx and metabolism in hepatic cells (Katsuya Nagaoka, et al.) published in Molecular and Cell Biology. The authors integrated transcriptomic, metabolomic and ChIP-Seq data to demonstrate the role of LSD2 in homeostatic control of the lipid metabolism in mouse hepatocytes. Avadis NGS was used to analyze and visualize the ChIP-Seq data.
Sex Specification and Heterogeneity of Primordial Germ Cells in Mice (Akihiko Sakashita,et al.) published in PLoS One. The authors report on female and male specific gene expression in the mouse primordial germ cells and the complex gene expression networks involved in PGC sex differentiation. RNA-Seq data analysis including quantification, normalization, fold change analysis and principal component analysis (bi-dimensional PCA) was performed in Strand NGS.
Congratulations to these authors and all the others who have seen their research efforts rewarded with a publication of their work.
This webinar, will highlight the Strand NGS Pipeline Manager feature. In this webinar, you will learn how to customize pipelines and share them with other Strand NGS users. This webinar will give a brief glimpse of an elaborate pipeline that aligns reads, filters poor-quality matches, computes coverage metrics, identifies variants, checks for sample cross-contamination, and emails quality reports – all from within Strand NGS. Vamsi will also be available for live questions at the event.

We are excited to be a part of the Annual Meeting of The American Society of Human Genetics (ASHG) again, this time in Baltimore, Maryland from 6- 10 October 2015. Come and meet us to learn more about our best-in-class next-generation sequencing (NGS) data analysis software Strand NGS and Agilent Technologies state-of-the-art multi-omics analysis software GeneSpring.
You can meet our representatives for a one-on-one discussion or a live demo of Strand NGS and GeneSpring suite at Agilent Technologies booth #701. To schedule a demo / one-on-one meeting, please write to us at firstname.lastname@example.org
The Strand team will also present four posters at the ASHG conference this year. One of our posters titled ‘Detection of translocations in clinical cancer samples using targeted NGS data‘, presented as part of the ‘Clinical Genetic Testing’ has scored high points by the ASHG reviewers committee and will feature among the top 10%, so make sure you mark your calendars to come and take a look. The other three posters will be presented in the ‘Bioinformatics and Genomic Technology’ sessions. Listed below are the details
Date: 7th Oct 2015
Session: Bioinformatics and Genomic Technology

Structural Variants (SVs) have long been implicated in many human diseases such as cancer, making their detection important in clinical genomics. Strand NGS 2.5 includes a new workflow step for detecting these variants based on split reads that span the breakpoints corresponding to the variants. Detection of SVs using split reads provides breakpoints with a higher precision compared to the methods based on paired-end reads. In this webinar, we will describe this method and demonstrate its application to detection of somatic gene fusions in targeted sequencing data. We will also show how the detected SVs can be visually validated in the elastic genome browser of Strand NGS.

In this month’s webinar, we will demonstrate and assess the algorithms in StrandNGS for both narrow and broad peak calling. Specifically, results from using ‘MACS’ algorithm for detecting the FOXA1 transcription factor binding sites and from ‘Find Enriched Regions’ approach for detecting histone H3K36 modification regions will be discussed.
Integrative RNA and ChIP-Seq analysis of regulatory T-cells , a Strand NGS application note describes how integrated multi-omics functionality in Strand NGS was used to find the regulatory role of FoxP3 in T-regulatory and T-helper cells. Learn how the gene expression profiles from RNA-Seq and FoxP3 DNA-protein binding sites from ChIP-Seq are integrated. For mor information, please write to us
