Abstract:
The two biological evidences to endorse the antiviral activity of RNA interference (RNAi) are biogenesis of viral-siRNA (v-siRNA) by the host and encoding of RNAi-suppressor protein by viral genome. It has been recently established that mammals and mammalian cell lines mount antiviral RNAi to defend themselves against the invading viruses. The large part of viral pathogenicity is also due to the RNAi suppressor proteins. In this context it is only natural to ask what kinds of RNAi suppressors are encoded by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the central character of the present pandemic. The following mini review addresses this question.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...
Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
