Insights

Long noncoding RNAs (lncRNAs) are crucial in cellular responses to DNA damage. Their functions, regulated by N6-adenosine methylation (m6A), are vital for maintaining genomic stability and preventing cancer.

Area of Science:

  • Molecular Biology
  • Genetics
  • Cancer Research

Background:

  • Chemotherapy and radiation induce DNA damage, leading to cell apoptosis.
  • DNA double-stranded breaks (DSBs) are a critical form of DNA damage.
  • Eukaryotic organisms possess complex DNA repair mechanisms to maintain genomic integrity.

Purpose of the Study:

  • To review the origin and functions of long noncoding RNAs (lncRNAs).
  • To highlight the involvement of lncRNAs in DNA damage response pathways.
  • To explore the regulatory role of N6-adenosine methylation (m6A) in lncRNA function.

Main Methods:

  • Literature review of studies on lncRNAs and DNA damage.
  • Analysis of lncRNA involvement in DNA repair mechanisms.
  • Examination of m6A modification's impact on lncRNA function in DNA damage response.

Main Results:

  • lncRNAs are significantly involved in cellular responses to DNA damage.
  • N6-adenosine methylation (m6A) dynamically regulates lncRNA roles in DNA repair.
  • Dysregulation of lncRNAs and their functions can contribute to tumorigenesis.

Conclusions:

  • lncRNAs are key players in the DNA damage response.
  • Understanding lncRNA regulation, including m6A modification, is crucial for cancer research.
  • lncRNAs' roles in gene expression and autophagy also link them to cancer development.

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...

Types of RNA01:20

Types of RNA

Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

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...

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
