Could rotavirus vaccine platforms aid in the immunization campaign against SARS-CoV-2?
Rotavirus is a common diarrheal disease that affects young children. Live oral rotavirus vaccines have been used to reduce its incidence in many countries. However, with the onset of the coronavirus disease 2019 (COVID-19) pandemic, and amid focus on vaccines…

Regulation of Gene Expression
Gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. Expression of genes can be controlled with the help of regulatory proteins at numerous levels. These regulatory proteins…

What is Sugar-Coated RNA?
“Sugar-coated RNA” is a term that was coined after a pre-printed article last year reported that some sugars seem to bind to RNAs, molecules that carry DNA instruction for protein synthesis and catalyze chemical reactions. Image Credits: nobeastsofierce /…

Researchers identify RNA molecule that helps lung cancer cells evade immune system
Researchers in Spain have identified a non-coding RNA molecule that helps lung cancer cells proliferate and avoid being killed by the body’s immune cells. The study, which will be published August 27 in the Journal of Cell Biology (JCB), suggests that…
