Overview of Gene Research
PPM1D, also known as wild-type p53-induced phosphatase 1 (Wip1) or protein phosphatase 2C delta (PP2Cδ), is a serine/threonine phosphatase. It negatively regulates crucial cancer suppressor pathways, especially those related to the DNA damage response, including the tumor suppressor p53 [2,4].
Using conditional mouse models, researchers found that Ppm1d regulates the competitive fitness and self-renewal of hematopoietic stem cells (HSCs) with and without exogenous genotoxic stresses [1]. In vitro and in vivo experiments showed that loss of Ppm1d sensitizes leukemias to cytotoxic therapies, even without a Ppm1d mutation [1]. In addition, in Diffuse Midline Gliomas (DMGs), PPM1D truncating mutations that increase phosphatase stability act as clonal driver events, and PPM1D phosphatase activity is required for in vivo oncogenesis [3].
In conclusion, PPM1D is an important regulator in the DNA damage response and cancer-related pathways. Conditional mouse models have revealed its role in hematopoiesis and gliomagenesis, suggesting its potential as a therapeutic target in myeloid malignancy and gliomas [1,3].
