RNAsignalvägar
RNAsignalvägar refers to the biological pathways that involve RNA molecules in the regulation of cellular processes. These pathways are critical for gene expression, development, and cellular response to stimuli. RNA molecules, beyond their well-known role as messengers in protein synthesis (mRNA), can act as regulators themselves. This includes microRNAs (miRNAs), small interfering RNAs (siRNAs), and long non-coding RNAs (lncRNAs), each participating in distinct signaling mechanisms.
MicroRNAs are short RNA molecules that typically bind to complementary sequences in target mRNAs, leading to
Small interfering RNAs play a similar role in gene silencing, often originating from exogenous sources like
Long non-coding RNAs are a diverse group of RNA molecules longer than 200 nucleotides that do not
Together, these different types of regulatory RNAs form complex RNAsignalvägar that are essential for cellular homeostasis
