Insights

Circular RNAs (circRNAs) interact with RNA-binding proteins (RBPs) to regulate gene expression in cancer. Understanding these circRNA-protein interactions (CPIs) is key to developing novel anti-cancer therapies.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • Circular RNAs (circRNAs) are a class of non-coding RNAs with regulatory roles in eukaryotes.
  • RNA-binding proteins (RBPs) are critical in cancer progression, influencing tumorigenesis, metastasis, and drug response.
  • circRNA-protein interactions (CPIs) are increasingly recognized for their impact on gene expression and cancer development.

Purpose of the Study:

  • To review recent advances in circRNA-protein interactions (CPIs) in cancer.
  • To discuss the functions and mechanisms of CPIs across gene expression stages.
  • To explore the role of CPIs in tumor drug resistance and potential therapeutic applications.

Main Methods:

  • Literature review of recent research on circRNA-protein interactions.
  • Analysis of studies detailing CPI functions in cancer gene expression.
  • Examination of evidence linking CPIs to cancer drug resistance.

Main Results:

  • CPIs influence gene expression at transcriptional, splicing, translational, and post-translational levels.
  • circRNAs modulate RBP activity, affecting tumor initiation, progression, and metastasis.
  • CPIs play a significant role in the development of tumor drug resistance.

Conclusions:

  • circRNA-protein interactions are crucial regulators in cancer biology.
  • Understanding CPIs offers potential for developing new anti-cancer therapeutic strategies.
  • Targeting CPIs may overcome drug resistance and improve cancer treatment outcomes.

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...

Regulation of Expression at Multiple Steps01:23

Regulation of Expression at Multiple Steps

The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

Epigenetic Regulation01:37

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Circadian Rhythms and Gene Regulation

The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Regulation of Expression Occurs at Multiple Steps

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

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...
