New study reports increased spread of B.1.1.7 variant in Houston, Texas

Research led by Jimmy Gollihar from the CCDC Army Research Laboratory-South in Austin, Texas found the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant B.1.1.7 —first detected last fall in England — increased in Houston, Texas. The B.1.1.7 variant is rapidly spreading with a case doubling time of 6.9 days.

FDA-approved cancer drug blunts SARS-CoV-2 protein's detrimental effects

University of Maryland School of Medicine (UMSOM) researchers have identified the most toxic proteins made by SARS-COV-2 - the virus that causes COVID-19 – and then used an FDA-approved cancer drug to blunt the viral protein's detrimental effects. In their experiments in fruit flies and human cell lines, the team discovered the cell process that the virus hijacks, illuminating new potential candidate drugs that could be tested for treating severe COVID-19 disease patients.

Researchers examine circRNAs encoded by MERS-CoV, SARS-CoV-1 and SARS-CoV-2

New research published in Briefings in Bioinformaticsm has identified thousands of circRNAs in Betacoronaviruses, including MERS-CoV, SARS-CoV-1, and SARS-CoV-2, from the RNA-sequencing data of viral infections. These coronaviruses have a similar genomic structure with a diverse circRNA coding ability. Researchers have also systematically characterized circRNAs in coronaviruses, with regard to their size, sequence feature, expressions, genome, location preference, and functions. This opens the door to further explore and understand the mode of action of individual circRNAs in coronaviruses.

Research finds polymerase of SARS-CoV-2 can adopt an alternative structure

New research by German scientists has uncovered another form of coronavirus polymerase. The current polymerase thought to be used for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a viral RNA-dependent RNA polymerase (RdRp) for replication and transcription. It contains a monomeric enzyme with the catalytic subunit nsp12, two copies of subunit nsp8, and one copy of subunit nsp7.
