Insights

N6-methyladenosine (m6A) RNA modification regulates gene expression and cancer progression. This review details m6A

Area of Science:

  • Epigenetics
  • Molecular Biology
  • Oncology

Background:

  • N6-methyladenosine (m6A) is a crucial reversible epigenetic modification of RNA.
  • m6A regulates gene expression by influencing RNA fate, controlled by 'writers' and 'erasers'.
  • m6A modification's role in cancer progression is a rapidly growing area of research.

Purpose of the Study:

  • To review the significance of m6A modification in noncoding RNAs (ncRNAs).
  • To summarize the mechanisms by which m6A affects ncRNA function.
  • To discuss the implications of m6A-modified ncRNAs in cancer and their potential for clinical treatment.

Main Methods:

  • Literature review focusing on m6A modification in various ncRNAs.
  • Analysis of mechanisms underlying m6A regulation of ncRNA.
  • Synthesis of current research on clinical applications of m6A-modified ncRNAs in oncology.

Main Results:

  • ncRNAs, once overlooked, play significant roles in various diseases, including tumors.
  • m6A modification is prevalent in different types of ncRNAs, influencing their stability, localization, and interactions.
  • Dysregulation of m6A modification in ncRNAs contributes to tumor initiation and progression, acting as either tumor-promoters or suppressors.

Conclusions:

  • m6A modification of ncRNAs is a key regulatory mechanism in cancer.
  • Understanding these modifications offers novel therapeutic strategies for cancer treatment.
  • Targeting m6A pathways in ncRNAs holds significant promise for clinical oncology.

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...

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 the pre-miRNA...

RNA Stability01:53

RNA Stability

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

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.

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
