Insights

MicroRNAs (miRNAs) are key gene regulators. Their abnormal levels, through oncomiRs or loss of tumor suppressors, drive cancer, emphasizing miRNA

Area of Science:

  • Molecular Biology
  • Genetics
  • Cancer Research

Background:

  • MicroRNAs (miRNAs) are crucial regulators of gene expression.
  • Dysregulation of miRNAs, including amplification of oncomiRs or loss of tumor suppressor miRNAs, is implicated in human cancer.
  • Global miRNA depletion due to alterations in miRNA biogenesis machinery is also oncogenic.

Purpose of the Study:

  • To highlight the significance of miRNA dysregulation in cancer.
  • To underscore the role of novel miRNA regulatory factors and pathways in tumorigenesis.

Main Methods:

  • Review of existing literature on miRNA function in gene regulation.
  • Analysis of genetic and epigenetic alterations affecting miRNA biogenesis.
  • Examination of the impact of individual miRNA alterations on tumorigenesis models.

Main Results:

  • Specific miRNA amplifications (oncomiRs) or losses promote cancer.
  • Genetic and epigenetic changes leading to global miRNA depletion contribute to oncogenesis.
  • Novel regulatory factors and pathways influencing miRNA activity have been identified.

Conclusions:

  • MiRNA dysregulation is a critical factor in cancer development.
  • Understanding miRNA regulatory networks is essential for cancer research.
  • Further investigation into novel miRNA pathways may reveal new therapeutic targets.

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 Nucleolus

The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...
