Exposure to ultraviolet light (UV) may cause a type of DNA mutation not previously known to be associated with skin cancer, according to researchers who sequenced the genome of UV-irradiated yeast samples.
A new understanding of why men are more prone to skin cancer
Men are genetically more prone to skin cancers such as melanoma, and now researchers may know why. According to investigators, the x chromosome contains three genes with significant mutations, of which one was only found in men.
Skin barrier gene defect linked to eczema in babies
Filaggrin gene defects may be linked to the development of eczema sooner than previously thought in newborn babies, based on information from a new study. Wheeze and nasal disease were also linked to the common skin barrier defect, according to the study published in the Journal of Allergy and Clinical Immunology (Apr. 28, 2020).
New insights into T cell reaction to UVR inflammation
Exposure to ultraviolet radiation causes a pair of specific T cell types in the skin to intervene to suppress inflammation and help the skin repair itself, according to a new study. The study, published online in Clinical & Translational Immunology (Apr. 2, 2020), found that T cells D4+GATA3+ and CD8+GATA3+ are sent to the inflamed area and can affect the area for two weeks.
Discovery of new RNA molecule could be key for early detection of skin cancer
The discovery of a new RNA molecule could lead to earlier detection of squamous cell carcinoma in the future, according to a new study. The study, published in the American Journal of Pathology (Feb. 2020; 190(2):503-517), found that the molecule, named PRECSIT, is integral in determining how squamous cell carcinoma grows and spreads.
