CZ ID: a cloud-based, no-code platform enabling advanced long read metagenomic analysis

Metagenomics has enabled the rapid, unbiased detection of microbes across diverse sample types, leading to exciting discoveries in infectious disease, microbiome, and viral research. However, the analysis of metagenomic data is often complex and computationally resource-intensive. CZ ID is a free, cloud-based genomic analysis platform that enables researchers to detect microbes using metagenomic data, identify antimicrobial resistance genes, and generate viral consensus genomes. With CZ ID, researchers can upload raw sequencing data, find matches in NCBI databases, get per-sample taxon metrics, and perform a variety of analyses and data visualizations. The intuitive interface and interactive visualizations make exploring and interpreting results simple. Here, we describe the expansion of CZ ID with a new long read mNGS pipeline that accepts Oxford Nanopore generated data (czid.org). We report benchmarking of a standard mock microbial community dataset against Kraken2, a widely used tool for metagenomic analysis. We evaluated the ability of this new pipeline to detect divergent viruses using simulated datasets. We also assessed the detection limit of a spiked-in virus to a cell line as a proxy for clinical samples. Lastly, we detected known and novel viruses in previously characterized disease vector (mosquitoes) samples.

Databiology Lab CORONAHACK: Collection of Public COVID-19 Data

COVID-19 has had an unprecedented global impact in health and economy affecting millions of persons world-wide. To support and enable a collaborative response from the global research communities, we created a data collection for different public sources for anonymized patient clinical data, imaging datasets, molecular data as nucleotide and protein sequences for the SARS-CoV-2 virus, reports of count of cases and deaths per city/country, and other economic indicators in Databiology Lab (https://www.lab.databiology.net/) where researchers could access these data assets and use the hundreds of available open source bioinformatic applications to analyze them. These data assets are regularly updated and was used in a successful virtual 3-day hackathon organized by Databiology Ltd and Mindstream-AI where hundreds of attendees to work collaboratively to analyze these data collections.

Overview of the expression of key regeneration genes in embryo development and matured tissues in Axolotl (Ambystoma mexicanum)

The axolotl is a Mexican endangered species with the capability to perform tissue regeneration in amputated extremities. Being an important research model, the complete genome of the Axolotl was sequenced in 2018 for the first time, revealing an enormous genome: the largest of any animal ever sequenced, and about 10 times larger than the human genome, a new landmark achievement in biology research. In this report, we collected 70 known genes that play an important role in tissue regeneration and searched for their expression during embryo development, regeneration, and in 6 adult tissues: the heart, liver, gills, front leg, rear leg, and tail. We observe those 70 genes expression levels in the 3 conditions and approximately 3 genes seem to be expressed exclusively in regeneration. This report displays a few insights on how this marvelous species can modulate its regenerative capabilities. There is still much more to explore with the Axolotl. Further research into their regenerative capabilities could provide researchers with the perspicacity to possibly accomplish human limb regeneration.
