Insights

MicroRNAs (miRNAs) are small RNAs regulating cell processes. Their dysregulation contributes to breast cancer development and progression, offering potential as therapeutic and diagnostic targets.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Breast cancer is a leading cancer in women, with unclear causes.
  • MicroRNAs (miRNAs) are small, non-coding RNAs regulating gene expression.
  • Aberrant miRNA expression is implicated in cellular dysfunction and disease progression.

Purpose of the Study:

  • To review the nature and function of miRNAs.
  • To elucidate the role of miRNAs in breast cancer etiology and progression.
  • To explore miRNA potential as therapeutic agents and diagnostic biomarkers.

Main Methods:

  • Literature review of scientific publications on miRNAs and breast cancer.
  • Analysis of miRNA biogenesis, function, and regulatory mechanisms.
  • Discussion of current research on miRNA involvement in oncogenesis and tumor suppression.

Main Results:

  • MicroRNAs regulate critical cellular processes including proliferation, differentiation, and apoptosis.
  • Dysregulated miRNA expression impacts oncogenes and tumor suppressor genes, driving breast cancer.
  • miRNAs demonstrate significant potential in breast cancer diagnostics and therapeutics.

Conclusions:

  • MicroRNAs play a crucial role in the molecular pathogenesis of breast cancer.
  • Targeting miRNAs offers promising avenues for novel breast cancer treatments.
  • miRNAs represent valuable biomarkers for early detection and prognosis of breast cancer.

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.
The mTOR pathway or the...

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)...
