  • Publication number: 20230272493
    Abstract: Methods of detecting, including early detection, of cancer mediated by SARS-CoV-2 and HPV, may include detection of such viral infections alone or together with one or more biomarkers selected from gene specific DNA methylation levels, whole genome DNA methylation levels, host RNA expression levels, T-Cell receptor amount or clonality, B-Cell receptor amount or clonality, microbiome. One method includes analysis of SARS-CoV-2 nucleic acid and the one or more biomarkers from samples of the same tissue, biofluid, or both. These methods are useful for, among other things, assessing the effectiveness of treatment, monitoring relapse, and clinical staging of cancer. These methods are also useful for among other things to monitor the effectiveness of strategies and therapies used to modify lifestyle and contextual effects to prevent disease, foster wellness and enable health promotion.

  • Patent number: 10457992
    Abstract: In accordance with one or more embodiments, the inventors have conducted the first comprehensive integrated genomic and epigenomic analysis in HNSCC, focusing on identifying genes that have concurrent promoter methylation, mutation and expression downregulation. The intersection of unbiased genome-wide methylation sequencing and methylation array screens uncovered 316 genes, which undergo promoter methylation in HNSCC. Close to 60% concordance was found between concurrent greater promoter methylation and gene downregulation, with PAX1 and PAX5 exhibiting the greatest expression loss. Methods for analyzing tissue samples from a subject for increased risk of poor survival outcomes from HNSCC are provided. Kits for measuring promoter methylation of the genes are also provided.

  • Patent number: 10428391
    Abstract: Methods and kits for triaging a human papillomavirus (HPV)-positive woman into colposcopy are disclosed. The methods comprise determining the promoter methylation level of the promoter regions of a group of genes (e.g., viral and host genes) that exhibit increased promoter methylation in women having CIN2+ lesions as compared to women having no intraepithelial lesions or malignancy (NILM).

  • Publication number: 20180223338
    Abstract: Methods for analyzing the bacterial microbiome of a subject and triaging the subject into treatment for head and neck squamous cell cancer from a saliva or tissue sample are provided. The methods also provide means for differentiation of different cancer patient cohorts from the bacterial microbiome of a subject.

  • Patent number: 9809864
    Abstract: Methods for the quantifying HPV Trans Renal DNA (TrDNA) from a urine sample from a subject using a dual sequence-capture approach are disclosed. The presently disclosed methods can be used to predict cancers including, but not limited to, cervical, anal, penile, and oropharyngeal cancers.

  • Publication number: 20170233817
    Abstract: The present invention relates to the field of cancer. More specifically, the present invention provides methods and compositions useful in the diagnosis and treatment of head and neck squamous cell carcinoma. As described herein, and particularly in reference to the figures, the present inventors have discovered that OTUs and several microbial communities at different taxonomic levels discriminates HNSCC from normal control samples, HPV+ and HPV? samples and pre- vs. post-surgical treatment samples. Appropriate diagnostic and treatment strategies can be employed based on the identification of the microbiota in patients' saliva.

  • Publication number: 20150045241
    Abstract: The present invention provides methods of determination of a global DNA methylation index (GDMI) in a sample from a subject, using a variety of methods which can detect global, genome-wide, and gene-specific DNA methylation to create methylation portraits that can be used for early detection, diagnosis, and clinical management in the personalized medicine space. Further, the invention provides methods of diagnosis of cancer, including gastric cancer and hepatocellular cancer in a subject, by comparing the GDMI in a sample obtained from a subject to the methylation index of standard controls. These methods allow diagnosis of gastric carcinoma and liver cancer in patients who may be asymptomatic or have inconclusive pathology, and allowing earlier treatment of the subject.
