Summary
Xeroderma pigmentosum complementation group C (XPC) protein, a DNA damage sensor, is elevated in basal cell carcinoma (BCC). Lower XPC levels correlate with high-risk BCC, suggesting a role in skin cancer development.
Area of Science:
- Molecular biology
- Dermatology
- Cancer research
Background:
- Xeroderma pigmentosum complementation group C (XPC) protein is a key DNA damage sensor.
- Mutations in XPC genes lead to photosensitivity and increased skin cancer risk.
- The distribution of XPC protein in basal cell carcinoma (BCC) is not well understood.
Purpose of the Study:
- To investigate the association between XPC protein and basal cell carcinoma (BCC).
- To analyze XPC protein expression levels in BCC tissues compared to normal skin.
Main Methods:
- Immunohistochemistry was used to examine XPC protein expression.
- The study included 86 cases of BCC and paired adjacent normal epidermis.
Main Results:
- Nuclear XPC expression was significantly higher in BCC tissues than in adjacent normal epidermis (p<0.001).
- Reduced XPC expression was linked to high-risk BCC (p=0.045).
- XPC expression levels did not show significant association with patient age, gender, or body area.
Conclusions:
- XPC protein is associated with basal cell carcinoma (BCC).
- Further research is needed to confirm if this XPC-BCC interaction is specific to certain cancer types.
- Investigating the underlying mechanisms of the XPC-BCC interaction is warranted.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

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...

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...

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,...

5.1K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...
