Insights

MicroRNAs regulate cancer stem cells, which drive tumor growth and relapse. Understanding these microRNAs offers new therapeutic targets for cancer treatment.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Cancer stem cells (CSCs) are a tumor subpopulation driving heterogeneity, treatment failure, and relapse.
  • The regulatory mechanisms governing CSCs remain largely undefined.
  • MicroRNAs (miRNAs) are small non-coding RNAs crucial for stem cell regulation.

Purpose of the Study:

  • To review the current understanding of microRNAs' role in cancer stem cell regulation.
  • To highlight miRNAs as potential therapeutic targets in various human malignancies.

Main Methods:

  • Literature review of studies investigating miRNA involvement in cancer stem cells.
  • Analysis of miRNA functions as tumor suppressors or oncogenes in CSCs.

Main Results:

  • Emerging evidence implicates miRNAs in the evolution and maintenance of cancer stem cells.
  • miRNAs function as either tumor suppressors or oncogenes in CSCs across diverse cancers.
  • miRNAs are implicated in critical gene expression pathways within CSCs.

Conclusions:

  • MicroRNAs play a significant role in regulating cancer stem cells.
  • Targeting miRNAs involved in CSC regulation presents a promising therapeutic strategy for cancer treatment.

Cancer Stem Cells and Tumor Maintenance

Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

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 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...

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells

A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
