Abstract

Insights

MicroRNAs (miRNAs) are key regulators in breast cancer progression and endocrine therapy resistance. Understanding their mechanisms offers promising new therapeutic strategies against this disease.

Area of Science:

  • Molecular Biology
  • Oncology
  • Genetics

Background:

  • Breast cancer is a leading cause of cancer death in women globally.
  • MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression.
  • Hormone-responsive miRNAs are implicated in breast cancer progression and endocrine therapy resistance.

Purpose of the Study:

  • To enhance understanding of microRNA (miRNA) roles in breast cancer.
  • To explore miRNA mechanisms for novel therapeutic development.
  • To identify miRNA targets for improved breast cancer treatment.

Main Methods:

  • This is a review article.
  • Focuses on summarizing existing research on miRNA mechanisms.
  • Covers signaling pathways, apoptosis, metastasis, cell cycle, ER-signaling, and drug resistance.

Main Results:

  • MicroRNAs (miRNAs) regulate key signaling pathways including TGF-beta and ER-signaling.
  • miRNAs are involved in critical cellular processes such as apoptosis and metastasis.
  • miRNA dysregulation contributes to breast cancer progression and drug resistance.

Conclusions:

  • MicroRNAs (miRNAs) show significant potential as therapeutic agents for breast cancer.
  • Targeting miRNAs could overcome endocrine therapy resistance.
  • Further research into miRNA mechanisms will advance breast cancer treatment.

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 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.

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.
