lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

9.7K
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...

Rous Sarcoma Virus (RSV) and Cancer

6.1K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Abnormal Proliferation02:23

Abnormal Proliferation

5.0K
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...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.6K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

The Ras Gene02:38

The Ras Gene

7.0K
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a...

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Pediatric solid tumors constitute approximately 40% of childhood cancers, arising from developmental disruptions in precursor cells.
  • Unlike adult tumors, pediatric tumors exhibit fewer genetic mutations in protein-coding genes, suggesting alternative oncogenic mechanisms.
  • Non-coding RNAs (ncRNAs) are crucial regulators of epigenetic and post-translational processes, implicated in oncogenic networks.

Purpose of the Study:

  • To review the role of ncRNAs in rare extracranial pediatric solid tumors.
  • To focus on microRNAs and long non-coding RNAs in the development of these cancers.
  • To emphasize the functional contributions and molecular interactions of ncRNAs in pediatric tumor formation.

Main Methods:

  • Literature review focusing on ncRNAs (microRNAs and long non-coding RNAs).
  • Analysis of the role of ncRNAs in the oncogenesis of rare extracranial pediatric solid tumors.
  • Examination of molecular interactions and functional contributions of ncRNAs in tumor development.

Main Results:

  • Evidence implicates ncRNAs in the regulation of oncogenic networks relevant to pediatric cancers.
  • MicroRNAs and long non-coding RNAs are highlighted as key players in the development of rare pediatric solid tumors.
  • ncRNAs influence epigenetic and post-translational regulation, contributing to tumor formation.

Conclusions:

  • Dysregulation of ncRNAs, including microRNAs and long non-coding RNAs, is likely critical in the pathogenesis of rare pediatric solid tumors.
  • Understanding ncRNA functions offers insights into the complex regulatory failures driving pediatric oncogenesis.
  • Further research into ncRNAs may reveal novel therapeutic targets for challenging childhood cancers.
