Taxonomic profiling of metagenomics samples: Get to know your loyal residents

Numerous colonies of different organisms live virtually everywhere on Earth, even in and on our bodies. They are called microbes and we all know about them. But do we really? Actually, the human race knew nothing about microbes before the 17th century. There were some assumptions and hypotheses, but their …

Differential Methylation Analysis

With few exceptions, every human cell is composed of an identical DNA sequence. However, there are around 200 different cell types in our bodies. What is the underlying reason? Each different cell type represents a specific gene expression pattern. One of the main mechanisms that enables this is epigenetics. Epigenetics …

Optimized Workflow for Bisulfite Sequencing Data Analysis

Epigenetics is an extra layer of information that is not encoded in the primary sequence of an organism’s DNA. While several mechanisms of epigenetic regulation exist, DNA methylation is one of the most commonly studied ones. Typically, the presence of methylated cytosines within a promoter region represses gene expression. The …

Spatial Transcriptomics on the Seven Bridges Platform

As our understanding of biology deepens, many researchers are moving away from bulk gene expression analyses to single-cell analyses. However, current RNA-Seq methods that assay pooled RNA from tissue samples, or even from single cells, fail to conserve the spatial distribution of gene expression within the original tissue. In addition, …

Smart Variant Filtering

The variant filtering process consists of selecting highly confident variants and removing the ones that are falsely called. Secondary genomic DNA analysis is mainly oriented toward alignment and variant calling, assuming the accuracy of these two would provide major influence on the overall quality. The variant filtering step used to …

Circulating Tumor DNA Analysis on the Seven Bridges Platform

Next Generation Sequencing (NGS) has brought significant improvements in all areas of biotechnology and healthcare — and cancer screening is no exception. The latest game-changer is liquid biopsy, a novel and challenging NGS application. By directly measuring and analyzing circulating tumor DNA (ctDNA) in blood, liquid biopsy is a promising, …
