Insights

Long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) play crucial roles in gastric cancer. Understanding their cross-talk offers new avenues for diagnosing and treating this deadly disease.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Gastric cancer is a leading cause of cancer mortality globally.
  • Current diagnostic and treatment strategies for gastric cancer have limitations.
  • The molecular mechanisms driving gastric cancer progression are not fully elucidated.

Purpose of the Study:

  • To review the current understanding of interactions between long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) in gastric cancer.
  • To highlight the role of lncRNA-miRNA cross-talk in gastric cancer development and progression.
  • To explore potential diagnostic and therapeutic applications of lncRNA-miRNA interactions.

Main Methods:

  • Literature review of recent research on lncRNA-miRNA interactions in gastric cancer.
  • Analysis of studies focusing on the regulatory roles of lncRNAs and miRNAs.
  • Synthesis of findings related to the cross-talk between these non-coding RNAs.

Main Results:

  • Non-coding RNAs, including lncRNAs and miRNAs, are critical regulators of cellular processes.
  • Complex cross-regulatory networks exist between lncRNAs and miRNAs.
  • lncRNA-miRNA interactions significantly influence gastric cancer pathogenesis.

Conclusions:

  • The intricate interplay between lncRNAs and miRNAs is a key factor in gastric cancer.
  • Targeting lncRNA-miRNA cross-talk presents promising opportunities for novel gastric cancer therapies.
  • Further research into these interactions can improve early detection and treatment outcomes for gastric cancer.

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...

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 the pre-miRNA...

Non-LTR Retrotransposons

As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
