Insights

Circular RNAs (circRNAs) are key regulators in human cancers, influencing processes like proliferation and metastasis. This review highlights how circRNAs modulate their host genes, impacting cancer progression and offering new therapeutic targets.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • Circular RNAs (circRNAs) are covalently closed RNA molecules with stable, tissue-specific expression.
  • They play critical roles in cancer, acting as tumor suppressors or oncogenes.
  • circRNAs function as miRNA/protein sponges, protein scaffolds, or translation templates.

Purpose of the Study:

  • To review the latest research on how circRNAs regulate their host genes in human cancers.
  • To elucidate the mechanisms by which circRNAs influence cancer progression via host gene modulation.
  • To enhance understanding of the circRNA-host gene interaction in the context of cancer.

Main Methods:

  • Literature review of recent studies on circRNA-host gene interactions in cancer.
  • Analysis of molecular mechanisms underlying circRNA-mediated gene regulation.
  • Synthesis of findings on the roles of circRNAs in cancer hallmarks.

Main Results:

  • circRNAs significantly impact cancer progression by modulating host gene expression and function.
  • These regulatory interactions are implicated in tumorigenesis, proliferation, apoptosis, metastasis, invasion, and chemoresistance.
  • circRNAs offer insights into novel diagnostic and therapeutic strategies for cancer.

Conclusions:

  • circRNAs are crucial regulators of host genes in human cancers.
  • Understanding circRNA-host gene interactions is vital for comprehending cancer biology.
  • Further research into these interactions may lead to targeted cancer therapies.

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...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Types of RNA

Overview
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 the regulation of 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.

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...
