This presentation will examine
RNA interference with a focus
on the mechanism of
RNA interference,
RNAI, its discovery, and
its fundamental role in
gene regulation and
cellular defense.
We'll outline the roles of
small interfering RNAs and
micro RNAs and how they guide
silencing complexes to
specific messenger RNAs.
The significance of RNAI
in development, disease,
and its application
in biotechnology
and medicine will be discussed,
along with therapeutic
advances and
challenges in specificity
and delivery.
Finally, we'll highlight
ongoing efforts
to overcome these obstacles,
expanding the potential of
RNAI in research and treatment.
We will explore RNA
interference or RNAI.
Discovered just over
two decades ago,
RNAI is a natural mechanism by
which cells regulate gene
expression and
defend themselves,
especially against
genomic parasites
like viruses and
transposable elements.
The core of RNAI involves
small RNA molecules that
recognize specific
messenger RNAs
and silence their expression.
RNAI is widely used in research,
biotechnology, and medicine and
shows promise for human
disease treatment.
At the heart of RNAI are
two families of
small RNA molecules,
small interfering
RNAs and microRNAs.
Both guide the RNA induced
silencing complex.
Double stranded RNA from
viruses or endogenous genes is
processed by DCR into 21
to 23 nucleotide sRNAs.
