The Retinoblastoma Gene

The 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,...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Genomic Imprinting and Inheritance

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Mismatch Repair

Mismatch Repair

Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...

Cancers Originate from Somatic Mutations in a Single Cell

Cancers Originate from Somatic Mutations in a Single Cell

Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Area of Science:

Ophthalmology
Genetics
Molecular Biology

Background:

DNA integrity is crucial for cellular function but is threatened by environmental mutagens.
Cells possess DNA repair mechanisms, but their failure can lead to genomic instability.
The role of genomic instability in eye diseases is an emerging area of research.

Purpose of the Study:

To review the association between genomic instability and specific ocular diseases.
To highlight the importance of DNA repair proteins in eye health.
To explore potential therapeutic strategies based on genomic stability.

Main Methods:

Literature review of studies on genomic instability and ocular diseases.
Analysis of the role of key DNA repair proteins (pRb, p53, RAD21) in ocular conditions.
Categorization of eye diseases based on their underlying mechanisms of genomic instability.

Main Results:

Five ocular diseases are associated with genomic instability: retinoblastoma, pterygium, Fuchs' corneal endothelial dystrophy, age-related macular degeneration, and sclerocornea.
Retinoblastoma and pterygium are linked to cell cycle abnormalities.
Fuchs' dystrophy and age-related macular degeneration involve DNA damage from oxidative stress and UV radiation, while sclerocornea is associated with cohesin complex mutations.

Conclusions:

Genomic instability, resulting from impaired DNA repair, contributes to ocular pathologies.
Understanding these links can inform novel therapeutic approaches for eye diseases.
Targeting genomic stability offers potential for disease prevention and treatment.
