This study found that selectively inactivating ribonucleotide excision repair in mouse epidermis leads to DNA damage, keratinocyte intraepithelial neoplasia, and squamous cell carcinoma, indicating a potential tumor-promoting mechanism related to compromised genome maintenance.

August 2018 in “Cancer research” In this study, researchers found that selectively disabling ribonucleotide excision repair in mouse epidermis caused DNA damage, skin inflammation, and led to skin cancer, suggesting a potential role for this repair mechanism in tumorigenesis.

July 2002 in “EMBO journal” This study found that RXRα/RARγ heterodimers are necessary for retinoic acid-induced keratinocyte proliferation in the skin, while normal epidermal maintenance does not require RAR-mediated signaling.
March 2026 in “The Journal of Steroid Biochemistry and Molecular Biology” This study found that mice lacking both vitamin D and calcium-sensing receptors in epidermal keratinocytes are predisposed to developing squamous cell carcinoma as they age, due to impaired oxidative stress response and reduced DNA repair capabilities.
August 2015 in “Free Radical Biology and Medicine” Some treatments can improve skin's defense against damage, but overuse may cause other skin problems.
