General Design Methods for mRNA Drugs

Pharma Mirror

Scientists have been striving to optimize mRNA stability, immunogenicity, translation efficiency, and delivery systems to achieve efficient and safe mRNA delivery. Messenger RNA (mRNA) is a single-stranded ribonucleic acid transcribed from the DNA chain, carrying the encoding information for protein synthesis.

New CRISPR-Based Tool Called PASTE Gene Editing Inserts Large DNA Sequences at Desired Sites

XTalks

Developed by MIT researchers Jonathan Gootenberg and Omar Abudayyeh, PASTE (Programmable Addition via Site-specific Targeting Elements) gene editing technology can insert genes as long as 36,000 DNA base pairs to liver cells in mice as well as several types of human cells.

Scientists implicate non-cardiac genes in congenital heart disease

Scienmag

CHAPEL HILL, NC – Inside embryonic cells, specific proteins control the rate at which genetic information is transcribed from DNA to messenger RNA – a crucial regulatory step before proteins are created. Then, organs develop and hopefully function properly.

Why Proviral DNA Drug Resistance Testing is Useful in Guiding Treatment Decisions for HIV-1 Patients

XTalks

Compared to standard plasma HIV-1 RNA drug resistance profiling, which requires a viral load of at least 500 copies per mL, proviral HIV-1 testing can be performed on samples with much lower virion counts of <50 copies per mL (below the detectable limit in RNA testing). Proviral DNA Genotyping. HIV Drug Resistance Testing.
