Abstract Text Tyrosine phosphorylation is important in signaling pathways underlying tumorigenesis. We performed a mutational analysis of the protein tyrosine kinase (PTK) gene family in cutaneous metastatic melanoma. We identified 30 somatic mutations affecting the kinase domains of 19 PTKs and subsequently evaluated the entire coding regions of the genes encoding these 19 PTKs for somatic mutations in 79 melanoma samples. We found ERBB4 mutations in 19% of individuals with melanoma and found mutations in two other kinases (FLT1 and PTK2B) in 10% of individuals with melanomas. We examined seven missense mutations in the most commonly altered PTK gene, ERBB4, and found that they resulted in increased kinase activity and transformation ability. Melanoma cells expressing mutant ERBB4 had reduced cell growth after shRNA-mediated knockdown of ERBB4 or treatment with the ERBB inhibitor lapatinib. These studies could lead to personalized therapeutics specifically targeting the kinases that are mutationally altered in individual melanomas.

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"

Sorting

  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.
