Versatile and efficient genome editing with Neisseria cinerea Cas9

PAM identification of NcCas9 by PAM-DOSE The type II-C Cas9 orthologue NcCas9 is of small size (1082 aa) and is closely related to conventional Neisseria meningitidis Cas9 (NmeCas9)11 (Fig. 1a). The NcCas9 is 94% identical to Nme1Cas9, and the divergences lie mainly in the C-terminal PAM-interacting domain (PID) (Fig. 1a and S1)….

Metagenomic analysis of viromes in tissues of wild Qinghai vole from the eastern Tibetan Plateau

Overview of the viromes In all, 41 wild Qinghai voles were collected from pasture habitats located on the eastern Tibetan Plateau, China (Fig. 1). Tissue samples from liver, lung, spleen, small intestine (with content), and feces (large intestinal content) of each vole were disrupted, and viral RNA was extracted. The RNA…

Uncharted genetic territory offers insight into human-specific proteins

When researchers working on the Human Genome Project completely mapped the genetic blueprint of humans in 2001, they were surprised to find only around 20,000 genes that produce proteins. Could it be that humans have only about twice as many genes as a common fly? Scientists had expected considerably more….

Roles of circRNAs | CMAR

Introduction Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer, with an increasing global incidence, and a leading cause of cancer-related mortality.1 Although hepatitis B and C virus infections, cirrhosis, alcohol intake, and non-alcoholic fatty liver disease (NAFLD) are the main risk factors contributing to HCC.1,2 Approximately…

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…

High-purity production and precise editing of DNA base editing ribonucleoproteins

Abstract Ribonucleoprotein (RNP) complex–mediated base editing is expected to be greatly beneficial because of its reduced off-target effects compared to plasmid- or viral vector–mediated gene editing, especially in therapeutic applications. However, production of recombinant cytosine base editors (CBEs) or adenine base editors (ABEs) with ample yield and high purity in…
