Webearlier findings that subtle variations in PTEN activity directly translate into cancer susceptibility [5]. Indeed, modest increases in PTEN activity translate into substan-tially improved cancer protection. PTEN and obesity Overexpression of PTEN in mice results in reduced body weight [12,13]. This phenotype is not surprising consider- WebFeb 4, 2016 · The recent establishment of Tyr:CreER;Braf V600E/+;Pten lox/lox mice (BP mice) in a C57BL/6 background, which spontaneously develop Braf-mutant, Pten-null melanomas after the induction of Cre expression, provides a valuable model to evaluate the therapeutic effects of cancer treatments in melanoma with PTEN loss .
