Xeroderma pigmentosum complementation group C (XPC) protein is crucial for DNA repair and preventing skin cancer. Emerging research highlights its broader role in non-dermatologic cancers, suggesting potential as a biomarker.
Area of Science:
- Molecular Biology
- Genetics
- Cancer Research
Background:
- Xeroderma pigmentosum complementation group C (XPC) protein initiates global-genomic nucleotide excision repair (GG-NER).
- XPC deficiency leads to UV-induced DNA damage and skin cancer susceptibility.
- XPC's role extends beyond GG-NER to other DNA repair pathways and cellular responses.
Purpose of the Study:
- To review the literature on XPC's role in non-dermatologic cancer.
- To explore XPC's involvement in DNA repair, damage response, and transcriptional regulation.
- To discuss XPC as a potential prognostic and therapeutic biomarker in various cancers.
Main Methods:
- Literature review of XPC's function in DNA repair.
- Analysis of XPC's involvement in non-dermatologic cancer development.
- Evaluation of XPC expression and polymorphisms as biomarkers.
Main Results:
- XPC is vital for GG-NER, protecting against UV-induced DNA damage and skin cancer.
- XPC influences non-dermatologic cancer development through multiple DNA repair and response pathways.
- XPC expression levels and genetic variations may impact cancer prognosis and treatment.
Conclusions:
- XPC plays a multifaceted role in cancer prevention and progression beyond its established function in GG-NER.
- XPC is a promising biomarker for predicting cancer development, progression, and treatment outcomes.
- Further research into XPC's functions could lead to novel therapeutic strategies for various cancers.

Nucleotide Excision Repair
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...
