Insights

Natural antisense transcripts (NATs) regulate gene expression and are implicated in cancer. This review highlights NATs' mechanisms in cancer biology and their therapeutic potential.

Area of Science:

  • Molecular Biology
  • Genetics
  • Cancer Research

Background:

  • Natural antisense transcripts (NATs) are RNA molecules transcribed from the opposite DNA strand, overlapping with sense transcripts.
  • NATs influence gene expression at multiple levels, including epigenetic, transcriptional, and post-translational modifications.
  • Dysregulation of NATs is observed in various cancers, suggesting their role in tumorigenesis.

Purpose of the Study:

  • To summarize current knowledge on NATs in cancer biology.
  • To elucidate the mechanisms by which NATs regulate cancer hallmarks.
  • To discuss the therapeutic potential of NATs in cancer treatment.

Main Methods:

  • Literature review and synthesis of existing studies on NATs in cancer.
  • Analysis of NATs' roles in epigenetic regulation, gene expression, and protein modification.
  • Exploration of NATs as potential biomarkers and therapeutic targets.

Main Results:

  • NATs play crucial roles in regulating key cancer pathways and hallmarks.
  • Specific NATs have been identified as potential oncogenes or tumor suppressors.
  • NATs offer novel avenues for targeted cancer therapies.

Conclusions:

  • NATs are pivotal regulators in cancer development and progression.
  • Targeting NATs presents a promising strategy for future cancer therapies.
  • Further research is needed to fully understand and exploit NATs' therapeutic potential.

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

siRNA - Small Interfering RNAs

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...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

Epigenetic Regulation01:37

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
