Insights

Oncogenic microRNAs (miRNAs) drive breast cancer progression by affecting cell migration, apoptosis, proliferation, and angiogenesis. This review explores miRNA-based therapies, including mimics and inhibitors, for targeted breast cancer treatment.

Area of Science:

  • Molecular Biology
  • Oncology
  • Biochemistry

Background:

  • Oncogenic microRNAs (miRNAs) play a critical role in breast cancer (BC) progression.
  • These miRNAs influence key hallmarks of cancer, including cell migration, invasion, metastasis, apoptosis inhibition, cell proliferation, and angiogenesis.
  • Understanding the specific roles of oncogenic miRNAs offers potential for novel targeted BC therapies.

Purpose of the Study:

  • To review the key oncogenic miRNAs implicated in breast cancer progression.
  • To discuss miRNA-based therapeutic strategies for targeted breast cancer treatment.
  • To summarize evidence for the clinical potential of miRNA-based therapies in breast cancer.

Main Methods:

  • Comprehensive literature review of oncogenic miRNAs in breast cancer.
  • Analysis of miRNAs involved in cell migration, invasion, metastasis, apoptosis, proliferation, and angiogenesis.
  • Examination of various miRNA-based therapeutic approaches, including mimics, inhibitors, sponges, nanoparticles, and artificial miRNAs.

Main Results:

  • Identified key oncogenic miRNAs (e.g., miR-9, miR-21, miR-155, miR-17/92) involved in multiple BC processes.
  • Detailed various miRNA-based therapeutic modalities such as miRNA mimics, anti-miRNA oligonucleotides (AMOs), miRNA sponges, and nanoparticles.
  • Highlighted the potential of these therapeutic strategies for clinical application in breast cancer treatment.

Conclusions:

  • Oncogenic miRNAs are crucial drivers of breast cancer and represent promising therapeutic targets.
  • miRNA-based therapies, including mimics and inhibition strategies, offer novel avenues for targeted BC treatment.
  • Further research and clinical translation of these miRNA-based approaches are warranted for effective breast cancer management.

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.

Cancer-Critical Genes II: Tumor Suppressor Genes

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...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
