Implications of Endogenous Small Regulatory RNAs on Gene Silencing in Mollusks

Cory Von Eiff, Beatriz Schueng Zancanela, Megan Gima, Kevin Quito, Manitejus Kotikalapudi, Sergio Valdivia, Yulica Santos‐Ortega, Alex Sutton Flynt

This study evaluates sRNA biogenesis in mollusks, finding no endogenous siRNA pathway but abundant piRNAs, with implications for RNAi applications in this phylum.

Processing of Genomic RNAs by Dicer in Bat Cells Limits SARS-CoV-2 Replication

Iyanuoluwani J. Owolabi, Shazeed-Ul Karim, Sweta Khanal, Sergio Valdivia, Christopher Frenzel, Fengwei Bai, Alex Sutton Flynt

The paper shows that Dicer processes SARS-CoV-2 genomic RNAs in bat cells, limiting viral replication, and highlights distinct antiviral mechanisms in bats compared to other mammals.
