Insights

Non-coding RNAs (ncRNAs) can encode polypeptides, challenging previous beliefs. These ncRNA-encoded polypeptides play crucial regulatory roles in cancer progression and evolution.

Area of Science:

  • Molecular Biology
  • Genetics
  • Cancer Research

Background:

  • Non-coding RNAs (ncRNAs) were traditionally considered non-protein-coding.
  • Recent findings indicate that certain ncRNAs can indeed produce polypeptides.
  • ncRNAs are increasingly recognized for their regulatory roles in diseases, especially cancer.

Purpose of the Study:

  • To explore the novel regulatory functions of polypeptides encoded by long non-coding RNA (lncRNA), primary miRNA (pri-miRNA), and circular RNA (circRNA).
  • To investigate the mechanisms by which these ncRNA-encoded polypeptides influence cancer.
  • To discuss the evolutionary implications of these polypeptides.

Main Methods:

  • Literature review of recent studies on ncRNA-encoded polypeptides.
  • Analysis of the functional roles of these polypeptides in cancer initiation and progression.
  • Examination of evolutionary conservation and emergence.

Main Results:

  • ncRNA-encoded polypeptides exhibit diverse regulatory functions in cancer.
  • These polypeptides interact with proteins and modulate signaling pathways.
  • They influence miRNA stability, cancer progression, malignancy, and drug resistance.

Conclusions:

  • ncRNA-encoded polypeptides represent a significant, newly discovered layer of gene regulation.
  • Their roles in cancer are multifaceted, impacting various clinical challenges.
  • Understanding these polypeptides offers new avenues for cancer research and therapy.
  • Their evolutionary emergence highlights a fundamental transition in molecular biology.

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...

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.

Experimental RNAi02:15

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

Nucleic Acid Structure01:25

Nucleic Acid Structure

The pentose sugar in DNA is deoxyribose, while in RNA the pentose sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the ribose's second carbon and a hydrogen on the deoxyribose's second carbon. The phosphate residue attaches to the hydroxyl group of the 5′ carbon of one sugar and the hydroxyl group of the 3′ carbon of the sugar of the next nucleotide, which forms  a 5′ to 3′ phosphodiester linkage.

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
