Abstract Text PTEN is known to be frequently mutated in uterine cancer and also dephosphorylates FAK. Here, we examined the impact of PTEN alterations on the response to treatment with a FAK inhibitor (GSK2256098). In vitro and in vivo therapeutic experiments were carried out using PTEN-mutated and PTEN-wild-type models of uterine cancer alone and in combination with chemotherapy. Treatment with GSK2256098 resulted in greater inhibition of pFAK(Y397) in PTEN-mutated (Ishikawa) than in PTEN-wild-type (Hec1A) cells. Ishikawa cells were more sensitive to GSK2256098 than the treated Hec1A cells. Ishikawa cells were transfected with a wild-type PTEN construct and pFAK(Y397) expression was unchanged after treatment with GSK2256098. Decreased cell viability and enhanced sensitivity to chemotherapy (paclitaxel and topotecan) in combination with GSK2256098 was observed in Ishikawa cells as compared with Hec1a cells. In the Ishikawa orthoptopic murine model, treatment with GSK2256098 resulted in lower tumor weights and fewer metastases than mice inoculated with Hec1A cells. Tumors treated with GSK2256098 had lower microvessel density (CD31), less cellular proliferation (Ki67), and higher apoptosis (TUNEL) rates in the Ishikawa model when compared with the Hec1a model. From a large cohort of evaluable patients, increased FAK and pFAK(Y397) expression levels were significantly related to poor overall survival. Moreover, PTEN levels were inversely related to pFAK(Y397) expression. These preclinical data demonstrate that PTEN-mutated uterine cancer responds better to FAK inhibition than does PTEN wild-type cancer. Therefore, PTEN could be a biomarker for predicting response to FAK-targeted therapy during clinical development.

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.

PTEN wild-type uterine cancer decreased response GSK2256098 Preclinical Actionable In a preclinical study, GSK2256098 treatment resulted in a decreased response in uterine cancer cells with PTEN wild-type versus uterine cancer cells harboring a PTEN mutation (PMID: 25833835). 25833835
PTEN mutant uterine cancer sensitive GSK2256098 + Paclitaxel Preclinical Actionable In a preclinical study, uterine cancer cells harboring a PTEN mutation were more sensitive to the combination of GSK2256098 and Taxol (paclitaxel) than uterine cancer cells wild-type for PTEN, resulting in decreased tumor growth in culture and in mouse models (PMID: 25833835). 25833835
PTEN mutant uterine cancer sensitive GSK2256098 + Topotecan Preclinical Actionable In a preclinical study, uterine cancer cells harboring a PTEN mutation were more sensitive to the combination of GSK2256098 and Hycamtin (topotecan) than uterine cancer cells wild-type for PTEN, resulting in decreased tumor growth in culture and in mouse models (PMID: 25833835). 25833835
PTEN mutant uterine cancer sensitive GSK2256098 Preclinical Actionable In a preclinical study, uterine cancer cells harboring a PTEN mutation demonstrated sensitivity to GSK2256098, resulting in inhibition of Ptk2 (Fak) phosphorylation, decreased tumor growth, and apoptosis both in culture and in mouse models (PMID: 25833835). 25833835
