  • Publication number: 20230046649
    Abstract: The current invention pertains to miRNAs that are differentially expressed in samples of an individual having pancreatic cancer, or having a high risk of developing pancreatic cancer, as compared to the corresponding sample of an individual not having pancreatic cancer, or having low risk of developing pancreatic cancer, respectively. In certain embodiments, the miRNAs are differentially expressed in a tissue sample or blood plasma sample of an individual having a pancreatic lesion and having a high risk of developing pancreatic cancer as compared to the corresponding tissue sample or blood sample of an individual having the pancreatic lesion and having no risk or low risk of developing pancreatic cancer. These differentially expressed miRNAs can be used as biomarkers for diagnosis, treatment, and/or prevention of pancreatic cancer, particularly, in a subject having a pancreatic lesion.

  • Patent number: 9528982
    Abstract: Despite initial sensitivity BAD-protein phosphorylation were evaluated in patient samples and cell lines as determinants of chemo-sensitivity and/or clinical outcome, and as therapeutic targets. Induced in-vitro OVCA cisplatin-resistance was associated with BAD-pathway expression. Expression of the pathway was also associated with resistance of 7 different cancers cell-types to 8 chemotherapeutic agents. Phosphorylation of the BAD-protein was associated with platinum-resistance in OVCA cells and primary OVCA specimens, and also overall patient survival. Targeted modulation of BAD-phosphorylation levels influenced cisplatin-sensitivity. A 47-gene BAD-pathway signature was associated in-vitro phospho-BAD levels and with survival of 838 patients with ovarian, breast, colon, and brain cancer. The survival advantage associated with both BAD-phosphorylation and also the BAD-pathway signature was independent of surgical cytoreductive status.

  • Patent number: 9195796
    Abstract: The invention provides for malignancy-risk gene signatures that predict the risk of developing breast cancer, the recurrence of breast cancer, and/or the metastasis of breast cancer. These signatures have numerous clinical applications including assessing risk of breast cancer development following routine breast biopsy, assessing the need for adjuvant radiotherapy after lumpectomy, and determining the need for completion mastectomy following lumpectomy for the breast cancer patient and other treatment plans that are personalized for the patient.

  • Patent number: 9063143
    Abstract: The phosphorylation status of the BAD protein is a determinant of ovarian cancer cell responsiveness to platinum chemotherapy. Indirect manipulation of BAD phosphorylation status influences cisplatin sensitivity. BAD phosphorylation represents a biomarker that predicts platinum sensitivity and is a therapeutic target to increase platinum sensitivity. The methods employ phospho-specific antibody against a particular amino acid residue or site. Phospho-specific protein characterization methods include immunohistochemical (IHC), flow cytometric, immunofluorescent, capture-and-detection, or reversed phase assay.

  • Patent number: 8741575
    Abstract: The present invention relates to biomarkers for neoplasias such as high grade gliomas. The inventors have discovered that the overexpression of senescence associated genes (SAG) is associated with a poor prognosis in subjects with high grade gliomas. The present invention provides SAG biomarkers for predicting response to therapy for subjects having high grade glioma based on dividing the samples into high and low risk groups; diagnosing high grade glioma; monitoring progression of high grade glioma from one biological state to another; and determining efficacy of treatment for high grade gliomas.

  • Publication number: 20130252831
    Abstract: A “malignancy-risk” (MR) gene signature score was developed with abundant proliferative genes using principal component analysis. This MR gene signature was shown to be a predictive and prognostic factor of overall survival in early-stage NSCLC. The malignancy-risk signature showed a significant association with OS, with poor survival seen in patients having a higher MR score and better survival seen in patients having a low MR score. As a prognostic factor, the MR gene signature showed a positive correlation with TNM stage, histologic grade, and smoking status. Combination of the MR signature with each clinical parameter often showed the best survival in the low MR group with good clinical outcome. The MR gene profile, tested with a PCA scoring method, discriminated overall survival in lung cancer patients was a predictor independent of pathological staging and other clinical parameters.
