Insights

MicroRNAs (miRNAs) regulate gene expression and are crucial in human diseases like cancer. Their varying levels in tissues and cancers can serve as diagnostic biomarkers.

Area of Science:

  • Molecular Biology
  • Genetics
  • Biochemistry

Background:

  • MicroRNAs (miRNAs) are novel regulators of gene expression.
  • Initially identified in invertebrates for developmental timing, their roles have expanded to diverse biological processes.
  • Emerging evidence highlights the significance of miRNAs in human diseases, particularly cancer.

Purpose of the Study:

  • To review the multifaceted roles of microRNAs in biological processes.
  • To explore the involvement of microRNAs in the development and progression of cancer.
  • To discuss the potential of microRNAs as therapeutic targets and diagnostic biomarkers in oncology.

Main Methods:

  • Literature review of studies on microRNA function and disease association.
  • Analysis of research on microRNAs as oncogenes and tumor suppressors.
  • Examination of data on miRNA expression profiles in various tissues and cancers.

Main Results:

  • MicroRNAs play critical roles in regulating gene expression across various biological functions.

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...

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.

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)...
