  • Phosphatase and tensin homolog is 47-kDa protein and was first identified as a candidate tumor suppressor gene in 1997 after its positional cloning from a region of chromosome 10q23 known to exhibit loss in a wide spectrum of tumor types. Since then, mutations of PTEN have been detected in a variety of human cancers including breast, thyroid, glioblastoma, endometrial, and prostate cancer, and melanoma. Inherited mutations in this gene also predispose carriers to develop Cowden's disease, a heritable cancer risk syndrome, and several related conditions. PTEN is classified as a tumor suppressor because its activity is lost by deletion, mutation, or through epigenetic changes.
  • PTEN protein has both protein phosphatase and lipid phosphatase activity.
  • the tumor suppressive function of PTEN has mainly been attributed to its lipid phosphatase activity, a role for PTEN protein phosphatase activity in cell-cycle regulation and inhibition of cell invasion in vitro has been suggested as well.
  • Loss of PTEN function seems to be responsible for many of the phenotypic features of melanoma, thus PTEN may serve as a potential target for drug development.
  • most types of tumors with PTEN alteration also carry other genetic changes, making the role of PTEN more ambiguous.
  • PTEN homozygous deletions and missense mutations alone are sufficient to cause tumorigenesis in certain tissues but not in others. However, even when mutation of PTEN alone has minimal effects, it frequently contributes to tumorigenesis in the context of other genetic alterations. See Aguissa-Toure et al., Cellular and Molecular Life Sciences 69: 1475-1491 (2012).
  • T cell-mediated immunotherapies are promising cancer treatments. However, many patients still fail to respond to these therapies. The molecular determinants of immune resistance are poorly understood. Loss of PTEN in tumor cells in preclinical models of melanoma inhibits T cell-mediated tumor killing and decreases T-cell trafficking into tumors. In patients (e.g., subjects), PTEN loss correlates with decreased T-cell infiltration at tumor sites, reduced likelihood of successful T-cell expansion from resected tumors, and inferior outcomes with PD-1 inhibitor therapy. PTEN loss in tumor cells increased the expression of immunosuppressive cytokines, resulting in decreased T-cell infiltration in tumors, and inhibited autophagy, which decreased T cell-mediated cell death.
  • PI3Kb selective RI3Kb
  • the PI3K pathway plays a critical role in cancer by regulating several critical cellular processes, including proliferation and survival.
  • One of the most common ways that this pathway is activated in cancer is by loss of expression of the tumor suppressor PTEN, which is a lipid phosphatase that dampens the activity of PI3K signaling. Loss of PTEN corresponds with increased activation of the PI3K-AKT pathway in multiple tumor types. Loss of PTEN occurs in up to 30% of melanomas, frequently in tumors with a concurrent activating BRAF mutation. Id.

  • PTEN deficient or “PTEN deficiency” refers to a cancer with a deficiency of the tumor suppressor function of PTEN, e.g., loss of expression of the PTEN tumor supporessor.
  • deficiency includes mutation in the PTEN gene, reduction or absence of PTEN protein when compared to PTEN wild-type, or mutation or absence of other genes that cause suppression of PTEN function. It includes PTEN activity or expression lost by deletion, mutation, or through epigenetic changes. Multiple mechanisms exist for the regulation of PTEN, including transcription, mRNA stability, microRNA (miRNA) targeting, translation, and protein stability.
  • PTEN is transcriptionally silenced by promoter methylation in endometrial, gastric, lung, thyroid, breast and ovarian tumors, as well as glioblastoma. Mutations resulting in the loss of function or reduced levels of PTEN, as well as PTEN deletions or alteration are found in many sporadic tumors. See Aguissa-Toure et al., supra.
