Insights

Malignant mesothelioma (MM), linked to asbestos, is aggressive. This review explores microRNAs (miRNAs) as key players in MM development, offering potential as diagnostic markers and therapeutic targets.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Malignant mesothelioma (MM) is an aggressive pleural tumor primarily caused by asbestos exposure.
  • MM has a poor prognosis, with median survival of 9-12 months and long latency periods.
  • Tumor aggressiveness is linked to genomic and gene expression alterations.

Purpose of the Study:

  • To review the role of microRNAs (miRNAs) in malignant mesothelioma (MM) tumorigenesis.
  • To analyze published miRNA expression data to understand MM carcinogenesis mechanisms.
  • To discuss the potential of miRNAs as diagnostic biomarkers, prognostic factors, and therapeutic targets in MM.

Main Methods:

  • Review of published scientific literature focusing on miRNA expression data in MM.
  • Analysis of differential miRNA expression profiles in MM cells versus normal mesothelial cells.
  • Evaluation of the mechanistic roles of miRNAs in MM oncogenesis.

Main Results:

  • miRNAs are small non-coding RNAs that regulate gene expression.
  • Deregulation of miRNAs is common in cancer, including MM.
  • Differential miRNA expression suggests roles as oncogenes or tumor suppressors in MM.

Conclusions:

  • miRNAs are significantly implicated in the development and progression of malignant mesothelioma.
  • miRNA expression profiles hold promise for early diagnosis and prognosis of MM.
  • Targeting miRNAs may offer novel therapeutic strategies for MM patients.

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.

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...
