Alterations in <i>MEK1/2</i> occur in cancers, both in the treatment-naïve state and following targeted therapies, most notably BRAF and MEK inhibitors in <i>BRAF</i>-V600E-mutant melanoma and colorectal cancer.

BRAF V600E is the predominantly occurring mutation of the cytoplasmic kinase BRAF, and, in colorectal cancer, its determination provides a diagnostic exclusion criterion for hereditary nonpolyposis colorectal cancer.

BRAF was mutated in 7.6% (484 of 6353) of colorectal cancer and 9.1% (29 of 317) of SBA samples, but V600E mutations were much less common in SBA, representing only 10.3% (3 of 29) of BRAF-mutated cases.

CIMP-specific inactivation of BRAF(V600E)-induced senescence and apoptosis pathways by IGFBP7 DNA hypermethylation might create a favorable context for the acquisition of BRAF(V600E) in CIMP+ colorectal cancer.

Circulating 25(OH)D was also inversely associated with <i>BRAF</i> V600E-positive colorectal cancer (per 25 nmol/L increment: HR, 0.71; 95% CI, 0.50-1.01).
