In addition, BRAF V600E mutations have been associated with oncogene-induced senescence in other benign tumors, providing clues to the pathogenesis of metanephric neoplasms in keeping with their overall benign behavior.
The presence of BRAF V600E and mitogen-activated protein kinase activation in a largely benign tumor supports the necessity for secondary events (e.g., p16 loss) in BRAF-driven oncogenesis.
To investigate the role of DUSP6 in the regulation of ERK1/2 (MAPK3/1)-dependent transcription, 42 benign neoplasms and 167 PTCs were retrospectively analyzed by immunohistochemistry with dideoxy sequencing to detect BRAF(V600E) mutation.
Human naevi (moles) are benign tumours of melanocytes that frequently harbour oncogenic mutations (predominantly V600E, where valine is substituted for glutamic acid) in BRAF, a protein kinase and downstream effector of Ras.
