Insights

N6-methyladenosine (m6A) RNA modifications and circular RNAs (circRNAs) interact to influence cancer development. Understanding this crosstalk offers new avenues for cancer diagnosis and treatment.

Area of Science:

  • Molecular Biology
  • Oncology
  • Epigenetics

Background:

  • N6-methyladenosine (m6A) is the most prevalent RNA modification, crucial in cancer.
  • Circular RNAs (circRNAs) are emerging regulators in biological processes.
  • m6A modification influences circRNA functions, and circRNAs target m6A regulators.

Purpose of the Study:

  • To review the functional crosstalk between m6A and circRNAs in cancer.
  • To illustrate the roles of m6A and circRNAs in cancer development.
  • To discuss potential applications and future research directions.

Main Methods:

  • Literature review of existing studies on m6A, circRNAs, and cancer.
  • Analysis of the mechanisms by which m6A affects circRNAs (biogenesis, stability, export).
  • Examination of how circRNAs regulate m6A regulators and target mRNAs.

Main Results:

  • m6A methylation impacts circRNA biogenesis, stability, and cytoplasmic export across various cancers.
  • circRNAs modulate the expression and degradation of m6A regulators.
  • circRNAs influence m6A modification of target mRNAs, affecting cancer progression.

Conclusions:

  • The interplay between m6A and circRNAs is integral to cancer development.
  • Further research into m6A and circRNAs can yield novel insights for cancer diagnosis and therapy.
  • Targeting this crosstalk presents potential therapeutic strategies for cancer patients.

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

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 Editing02:23

RNA Editing

RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...

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...

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...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
