Loss of CDKN2A expression is a frequent event in primary invasive melanoma and correlates with sensitivity to the CDK4/6 inhibitor PD0332991 in melanoma cell lines
Excerpt:
In 47 melanoma cell lines homozygous loss, methylation or mutation of CDKN2A gene or loss of protein (p16INK4A) predicted sensitivity to the CDK4/6 inhibitor PD0332991, while RB1 loss predicted resistance.
