Summary
Retinoblastoma research, initiated by the RB1 tumor suppressor gene discovery, continues to explore genetic events driving cancer progression. Understanding phenotypic variations offers insights into uncontrolled cell proliferation and retinoblastoma pathogenesis.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Retinoblastoma research established the 'two-hit model' of oncogenesis.
- The RB1 gene was the first identified tumor suppressor gene.
- Understanding retinoblastoma pathogenesis requires investigating genetic and stochastic events in cell proliferation.
Purpose of the Study:
- To review recent developments in retinoblastoma research.
- To elucidate the molecular basis of retinoblastoma phenotypic variations.
- To revise the understanding of retinoblastoma pathogenesis and progression.
Main Methods:
- Comparative genomic hybridization (CGH) studies.
- Gene expression profiling.
- Review of existing literature on retinoblastoma.
Main Results:
- Phenotypic variations in retinoblastoma provide clues to disease pathogenesis.
- Gene expression and CGH studies probe genes controlling cellular development (proliferation, differentiation, apoptosis).
- Research is ongoing to identify the cell of origin for retinoblastoma.
Conclusions:
- Recent advancements are reshaping the understanding of retinoblastoma pathogenesis.
- Further research into genetic events and cell of origin is crucial.
- Elucidating molecular mechanisms will enhance insights into tumor progression.

01:20The Retinoblastoma Gene
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,...

01:03Rous Sarcoma Virus (RSV) and Cancer
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.
