Insights

MicroRNAs (miRNAs) show promise as biomarkers for pediatric central nervous system (CNS) tumors. Further research into miRNA profiling can improve diagnosis, prognosis, and targeted therapies for these aggressive childhood cancers.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Childhood central nervous system (CNS) tumors remain a significant cause of mortality despite treatment advances.
  • Identifying molecular targets is crucial for improved diagnostics, prognostics, and targeted therapies.
  • MicroRNAs (miRNAs) are increasingly recognized for their role in cancer development and progression.

Purpose of the Study:

  • To provide an overview of recent advances in the diagnostic and prognostic potential of miRNAs in pediatric CNS tumors.
  • To highlight the scarcity of microRNA profiling studies in pediatric tumors.
  • To explore the role of miRNA dysregulation as an epigenetic driver of tumorigenesis.

Main Methods:

  • Literature review of recent advances in miRNA research for pediatric CNS tumors.
  • Focus on specific tumor types: medulloblastoma, ependymoma, pilocytic astrocytoma, glioblastoma, diffuse intrinsic pontine glioma, atypical teratoid/rhabdoid tumors, and choroid plexus tumors.
  • Analysis of the diagnostic, prognostic, and therapeutic implications of miRNA dysregulation.

Main Results:

  • MicroRNA dysregulation is implicated as an epigenetic driver in tumorigenesis.
  • Recent advances demonstrate the diagnostic and prognostic potential of miRNAs in various pediatric CNS tumors.
  • MicroRNA profiling offers a promising avenue for targeted therapeutic strategies.

Conclusions:

  • MicroRNAs hold significant potential as biomarkers for pediatric CNS tumors.
  • Further microRNA profiling studies are warranted to fully elucidate their role in diagnosis, prognosis, and treatment response.
  • Targeted therapies based on miRNA modulation could revolutionize childhood CNS cancer treatment.

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...

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...

Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

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.
The mTOR pathway or the...

lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
