Insights

MicroRNAs (miRNAs), small regulatory RNAs, are newly recognized players in human cancer development. These molecules are crucial in tumorigenesis and offer potential as novel diagnostic and therapeutic anti-cancer tools.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Traditionally, cancer was viewed as a genetic disease driven by protein alterations.
  • Emerging research highlights the significant role of microRNAs (miRNAs) in human tumorigenesis.
  • miRNAs represent a critical regulatory layer in the molecular landscape of cancer.

Purpose of the Study:

  • To summarize recent advancements in understanding miRNA involvement in human cancer.
  • To illustrate the potential clinical applications of miRNA research in medical practice.

Main Methods:

  • Review of gene expression studies identifying deregulated miRNAs in cancer cells.
  • Analysis of functional studies elucidating the role of miRNAs in tumorigenesis.

Main Results:

  • Hundreds of miRNAs are found to be deregulated in various cancer types.
  • miRNAs are implicated in all molecular and biological processes driving cancer development.

Conclusions:

  • miRNAs are integral to the molecular basis of human cancer.
  • miRNAs hold promise for developing new diagnostic classifiers for cancer detection.
  • miRNAs are emerging as potential novel therapeutic agents for anti-cancer strategies.

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.

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...

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
