September 2019 in “Journal of Cell Biology” This study found that despite carrying an activating Hras mutation, hair follicle stem cells integrate into normal skin without causing tumors, unlike similar mutations in the epidermis, suggesting unique tumor-suppressing mechanisms in hair follicles.
This study found that GNAQQ209L expression in mouse melanocytes led to reduced survival in the interfollicular epidermis due to paracrine signaling, while GNAQQ209L boosted survival in a different microenvironment.
In this study, researchers discovered that the HrasG12V oncogenic mutation in murine skin epithelial cells initially promotes progenitor cell renewal but later leads to a balanced differentiation, stabilizing clone growth.
