Insights

MicroRNAs (miRNAs) and other non-coding RNAs (ncRNAs) play crucial roles in gene regulation and cancer development. Research highlights their potential as diagnostic tools and novel anti-cancer therapies.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • Non-coding transcripts, including microRNAs (miRNAs), are increasingly recognized for their roles in gene regulation and RNA processing.
  • The complex network of non-coding RNAs (ncRNAs) suggests the existence of unidentified molecular classes involved in transcriptional regulation.
  • MicroRNAs and other ncRNAs are implicated in human tumorigenesis, adding a new dimension to cancer's molecular landscape.

Purpose of the Study:

  • To summarize recent advancements in understanding the involvement of miRNAs and other ncRNAs in cancer.
  • To illustrate the potential clinical applications of this knowledge in medical practice.
  • To highlight the diagnostic and therapeutic potential of miRNAs in oncology.

Main Methods:

  • Review of recent scientific literature on non-coding RNAs and cancer.
  • Analysis of gene expression studies identifying deregulated miRNAs in cancer cells.
  • Examination of functional studies elucidating the role of miRNAs in tumorigenesis.

Main Results:

  • Hundreds of miRNAs are deregulated in cancer cells, indicating widespread involvement in the disease.
  • Functional studies confirm that miRNAs are integral to all molecular and biological processes driving tumorigenesis.
  • Emerging evidence points to the utility of miRNAs in cancer diagnostics and therapeutics.

Conclusions:

  • MicroRNAs and other non-coding RNAs represent a significant layer in cancer's molecular architecture.
  • Understanding these molecules offers new avenues for cancer diagnosis, with miRNA-based classifiers on the horizon.
  • MicroRNAs hold promise as novel therapeutic agents for anti-cancer treatments.

lncRNA - Long Non-coding RNAs02:39

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 (lncRNA)...

Cancer-Critical Genes I: Proto-oncogenes01:33

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...

mTOR Signaling and Cancer Progression03:03

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.
