siRNA - Small Interfering RNAs

17.3K
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
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...

Experimental RNAi

6.5K
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

RNA Interference

26.8K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
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...

Area of Science:

  • Biochemistry
  • Computational Biology
  • Peptide Science

Background:

  • Antisense peptide technology (APT) is a heuristic algorithm for rational peptide design.
  • Empirical data suggests peptides with complementary amino acids exhibit higher interaction probability and affinity.
  • This interaction is linked to the genetic code's structure, independent of codon translation direction.

Purpose of the Study:

  • To explore the concept of complementary peptide interaction.
  • To summarize potential applications of APT in diagnostics and bioengineering.
  • To address challenges and propose solutions for APT implementation.

Main Methods:

  • The study discusses the theoretical underpinnings of complementary peptide interactions.
  • APT methodology was validated using the SARS-CoV-2 model.
  • The CABS-dock server was employed for binding predictions.

Main Results:

  • The CABS-dock server accurately predicted antisense peptide binding to the SARS-CoV-2 receptor binding domain.
  • Binding site predefinition was not necessary for accurate predictions.
  • The study demonstrated the practical application of APT in a viral context.

Conclusions:

  • APT offers a rational approach to peptide design with significant advantages over random screening.
  • The technology has the potential for considerable time and resource savings.
  • Combining APT with computational and immunochemical methods can enhance its utility.
