Abstract
Systems, methods, and computer readable media for diagnosing or characterizing epithelial cancer or its stages based on the level of expression of the Wnt5a gene or protein are provided. The level of nucleic acids encoding Wnt5a or the level of Wnt5a protein is measured in a tissue sample, and the level is compared with reference values. Methods for inducing senescence of an epithelial cancer cell are also provided.
Claims5
A method, comprising detecting Wnt5a protein levels that are lower than the Wnt5a protein levels of normal ovarian epithelial cells or normal fallopian tube epithelial cells in an epithelial ovarian tumor, and inducing senescence in cells of the tumor by contacting the cells with an amount of Wnt5a protein, or biologically active fragment thereof, effective to activate the histone repressor A (HIRA)/promyelocytic leukemia (PML) pathway in the cells, thereby inducing senescence in the cells of the tumor.
A method, comprising detecting Wnt5a mRNA levels that are lower than the Wnt5a mRNA levels of normal ovarian epithelial cells or normal fallopian tube epithelial cells in an epithelial ovarian tumor, and inducing senescence in cells of the tumor by contacting the cells with an amount of Wnt5a protein, or biologically active fragment thereof, effective to activate the histone repressor A (HIRA)/promyelocytic leukemia (PML) pathway in the cells, thereby inducing senescence in the cells of the tumor.
