Title Inhibitor-sensitive FGFR2 and FGFR3 mutations in lung squamous cell carcinoma.
URL
Abstract Text A comprehensive description of genomic alterations in lung squamous cell carcinoma (lung SCC) has recently been reported, enabling the identification of genomic events that contribute to the oncogenesis of this disease. In lung SCC, one of the most frequently altered receptor tyrosine kinase families is the fibroblast growth factor receptor (FGFR) family, with amplification or mutation observed in all four family members. Here, we describe the oncogenic nature of mutations observed in FGFR2 and FGFR3, each of which are observed in 3% of samples, for a mutation rate of 6% across both genes. Using cell culture and xenograft models, we show that several of these mutations drive cellular transformation. Transformation can be reversed by small-molecule FGFR inhibitors currently being developed for clinical use. We also show that mutations in the extracellular domains of FGFR2 lead to constitutive FGFR dimerization. In addition, we report a patient with an FGFR2-mutated oral SCC who responded to the multitargeted tyrosine kinase inhibitor pazopanib. These findings provide new insights into driving oncogenic events in a subset of lung squamous cancers, and recommend future clinical studies with FGFR inhibitors in patients with lung and head and neck SCC.

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. 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 on a longer phrase with spaces (i.e. "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.

Votrient (pazopanib) is approved for renal cell carcinoma and soft tissue sarcoma (FDA.gov).
Gene Variant Impact Protein Effect Variant Description Associated with drug Resistance
FGFR2 K659E missense gain of function FGFR2 K659E (also referred to as K660E from the FGFR2IIIb isoform) lies within the protein kinase domain of the Fgfr2 protein (UniProt.org). K659E results in a growth advantage relative to wild-type Fgfr2 in a competition assay and increased transformation activity in cultured cells (PMID: 34272467), increased phosphorylation of downstream signaling molecules, induces colony formation in culture (PMID: 23786770), and results in the ability to induce senescence and cooperate with Myc to induce transformation of cell lines in culture (PMID: 19403560).
FGFR2 K660E missense gain of function FGFR2 K660E (corresponds to K659E in the canonical isoform) lies within the protein kinase domain of the Fgfr2 protein (UniProt.org). K660E results in increased phosphorylation of Fgfr2, activation of downstream signaling, and is transforming in cell culture (PMID: 23786770). Y
FGFR2 P253R missense gain of function - predicted FGFR2 P253R lies within the extracellular domain of the Fgfr2 protein (UniProt.org). P253R results in transformation activity similar to wild-type Fgfr2 in one study (PMID: 34272467), but a growth advantage relative to wild-type Fgfr2 in a competition assay (PMID: 34272467), loss of ligand specificity, activation of the p38/MAPK pathway in transgenic mouse models, and is transforming in cell culture (PMID: 11121055, PMID: 20175913, PMID: 23786770), and therefore, is predicted to lead to a gain of Fgfr2 protein function.
FGFR2 W290C missense gain of function FGFR2 W290C lies within the Ig-like C2-type domain 3 of the Fgfr2 protein (UniProt.org). W290C does not result in increased Fgfr2 phosphorylation, but increases both ligand-dependent and ligand-independent dimerization of Fgfr2 (PMID: 23786770), results in a growth advantage relative to wild-type Fgfr2 in a competition assay (PMID: 34272467), is transforming in cell culture (PMID: 23786770, PMID: 34272467), and promotes tumor formation in xenograft models (PMID: 23786770).
