Protein Effect no effect
Gene Variant Descriptions PTEN dec exp indicates decreased expression of the Pten protein and/or mRNA. However, the mechanism causing the decreased expression is unspecified.
Associated Drug Resistance
Category Variants Paths

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.

PTEN dec exp renal cell carcinoma no benefit Everolimus Case Reports/Case Series Actionable In a retrospective analysis from a Phase II clinical trial, patients with metastatic renal cell carcinoma treated with Afinitor (everolimus) had no difference in progression-free survival when stratified by high expression (n=17) and low expression (n=21) of Pten (PMID: 26951309). 26951309
PTEN dec exp triple-receptor negative breast cancer sensitive Ipatasertib Preclinical - Pdx Actionable In a preclinical study, Ipatasertib (GDC-0068) reduced tumor growth in a patient-derived xenograft (PDX) model of triple-negative breast cancer with low PTEN expression (PMID: 32205017). 32205017
PTEN dec exp renal cell carcinoma no benefit Apitolisib Case Reports/Case Series Actionable In a retrospective analysis from a Phase II clinical trial, patients with metastatic renal cell carcinoma treated with Apitolisib (GDC-0980) had no difference in progression-free survival when stratified by high expression (n=17) and low expression (n=19) of Pten (PMID: 26951309). 26951309
PTEN dec exp Advanced Solid Tumor sensitive GSK2636771 Phase Ib/II Actionable In a Phase I/II trial, GSK2636771 treatment inhibited Akt signaling, and resulted in partial response in 2% (1/53) and stable disease in 25% (13/53) of patients with PTEN-deficient advanced solid tumors (J Clin Oncol 32:5s, 2014 (suppl; abstr 2514)). detail...
PTEN dec exp melanoma sensitive SAR260301 Preclinical - Cell line xenograft Actionable In a preclinical study, SAR260301 inhibited tumor growth in xenograft models of melanoma cell lines harboring PTEN deficiency (PMID: 24387221). 24387221
PTEN dec exp melanoma decreased response Nivolumab Clinical Study - Cohort Actionable In a clinical study, melanoma patients with PTEN expression in less than 10% of tumor cells demonstrated decreased response to anti-PD-1 antibodies, including Opdivo (nivolumab), as compared to patients in which PTEN is present in over 10% of tumor cells (PMID: 26645196). 26645196
PTEN dec exp triple-receptor negative breast cancer predicted - sensitive Alpelisib + Everolimus Preclinical - Pdx & cell culture Actionable In a preclinical study, combination treatment with Piqray (albelisib) and Afinitor (everolimus) synergistically inhibited cell viability of PTEN-deficient triple-negative breast cancer patient-derived cells in culture, and led to inhibition of tumor growth in patient-derived xenograft (PDX) models (PMID: 36900375). 36900375
PTEN dec exp melanoma decreased response Pembrolizumab Clinical Study - Cohort Actionable In a clinical study, melanoma patients with PTEN expression in less than 10% of tumor cells demonstrated decreased response to anti-PD-1 antibodies, including Keytruda (pembrolizumab), compared to patients in which PTEN is present in over 10% of tumor cells (PMID: 26645196). 26645196
PTEN dec exp Advanced Solid Tumor predicted - sensitive Pemetrexed Disodium + Sorafenib Phase I Actionable In a Phase I clinical trial, low Pten expression or lack of Pten expression was associated with better response to treatment with the combination of Alimta (pemetrexed) and Nexavar (sorafenib) in patients with advanced solid tumors (PMID: 27213589). 27213589
PTEN dec exp triple-receptor negative breast cancer predicted - sensitive Ipatasertib + Paclitaxel Phase II Actionable In a Phase II trial, Ipatasertib (GDC-0068) in combination with Abraxane (paclitaxel) resulted in improved progression free survival (6.2 vs 3.7 months) compared to placebo in triple-receptor negative breast cancer patients with low Pten expression (PMID: 28800861; NCT02162719). 28800861
