PTEN and melanoma: We administered MitoQ and its control compound decyl-TPP (dTPP) in the drinking water of 3-week-old BrafCA/+Ptenfl/flTyr-Cre0/+ mice (designated BPT mice) [16] with early stages of malignant melanoma (they had been painted with tamoxifen on the flank skin 2–3 days after birth to activate BRAFV600E expression and inactivate Pten in melanocytes).
