New bioinformatics method to analyze viral sgRNA

Single guide ribonucleic acid (sgRNA) molecules are produced by discontinuous transcription, in which viral RNA-dependant RNA polymerase pauses early negative-sense RNA synthesis and then jumps to the other end of the genome. The specifics of this process are still not fully understood. Since sgRNAs can play an important role in…

Large-scale genome-wide study reveals climate adaptive variability in a cosmopolitan pest

Genomic data The foundational resource for this study was a dataset of 40,107,925 nuclear SNPs sequenced from a worldwide sample of 532 DBM individuals collected in 114 different sites based on our previous project15. DNA was extracted from each of the 532 individuals using DNeasy Blood and Tissue Kit (Qiagen,…

eli5 RNA Spike-ins : explainlikeimfive

I’m a data scientist trying to branch out into more bioinformatics/genetics. My tutorial is counting spike-ins, but his explanation was over my head: 1 – AnnData and Preprocessing spike-ins | Kaggle ” Because this is smartseq2 data, we may have spike-ins. An RNA spike-in is an RNA transcript of known…

Startup BugSeq Bioinformatics Achieves High SARS-CoV-2 Detection Rate With Nanopore Sequencing

CHICAGO – Canadian startup BugSeq Bioinformatics has devised a method of detecting pathogens via metagenomic nanopore sequencing that the company says is more accurate and sensitive than PCR and microbial cultures. Notably, the technology does not need to target specific pathogens like PCR and microbial culture tests must. The firm…

Pericentromeric noncoding RNA changes DNA binding of CTCF and inflammatory gene expression in senescence and cancer

Significance During the aging process, senescent cells secrete inflammatory factors, causing various age-related pathologies. Thus, controlling the senescence-associated secretory phenotype (SASP) can tremendously benefit human health. Although SASP seems to be induced by the alteration of chromosomal organization, its underlying mechanism remains unclear. Here, it has been revealed that noncoding…
