Described are devices for treating disease in subjects wherein the devices include a sponge comprising a hydrogel, extracellular vesicles (EVs), and an agent. Methods of using the devices to treat or prevent disease such as esophageal adenocarcinoma are also described.

Device and method to treat esophageal disorders

The present invention relates to the field of gastric cancer. More specifically, the present invention provides methods and compositions for diagnosing and treating gastric cancer. In a specific embodiment, a method for diagnosing gastric cancer or a likelihood thereof in a patient comprises the steps of (a) providing a sample from the patient; (b) measuring the methylation levels of one or more biomarkers in the sample collected from the patient; and (c) predicting gastric cancer in the patient if the biomarkers are hypermethylated. In a more specific embodiment, the one or more biomarkers comprises tight junction protein claudin-1 1 (CLD-N11), the transcription factor BarH-like homeobox (BARX1), basonuclin1 (BNC1), Coagulation factor C homolog (COCH), filamin C gamma (FLNC), cytoglobin B (CYGB), glutamine-fructose-6-phospahe-transaminase-2 (GFPT2), heat-shock-70 kDa protein-6 (HSPA6), snail homolog 1 (SNAL1), skin calmodulin-related factor (SCARF), and tumor protein p53 binding protein 2 (TP53BP2).

Methods and compositions for diagnosing and treating gastric cancer

The present invention relates to the field of cancer. More specifically, the present invention relates to the use of biomarkers to detect colorectal cancer. In one aspect, the present invention provides methods for qualifying colorectal cancer status including, but not limited to, diagnosis, prognosis, and risk stratification, in patients. In one embodiment, a method for diagnosing colorectal cancer (CRC) in a patient comprises the steps of (a) collecting a sample from the patient; (b) measuring the methylation levels of one or more biomarkers in the sample collected from the patient; and (c) comparing the methylation levels of the one or more biomarkers with predefined methylation levels of the same biomarkers that correlate to a patient having CRC and predefined methylation levels of the same biomarkers that correlate to a patient not having CRC, wherein a correlation to one of the predefined methylation levels provides the diagnosis.

DNA hypermethylation diagnostic biomarkers for colorectal cancer

This invention relates, e.g., to methods for predicting a subject's risk for developing esophageal adenocarcinoma (EAC) or high-grade dysplasia (HGD), comprising determining in a sample from the subject the methylation levels of transcriptional promoter regions of various combinations of, among other genes, (a) cadherin 13, H-cadherin (heart) (CDH13); (b) tachykinin-1 (TAC1); (c) nel-like 1 (NELL1); (d) A-kinase anchoring protein 12 (AKAP12); (e) somatostatin (SST); (f) transmembrane protein with EGF-like and two follistatin-like domains (HPP1); (g) CDKN2a, cyclin-dependent kinase inhibitor 2a (p16); or (h) runt-related transcription factor 3 (RUNX3).

Methods for predicting esophageal adenocarcinoma (EAC)

The present invention relates to the field of biomarkers. More specifically, the present invention relates to the use of microRNAs to diagnose and monitor various diseases such as cancer. In particular embodiments, microRNA expression levels can serve as diagnostic biomarkers in inflammatory bowel disease-associated neoplasia (IBDN). More specifically, in certain embodiments, the present invention can be used to differentiate or distinguish IBDN from sporadic colorectal cancer (S-CRC), IBD-Dysplasia, IBD and/or normal.

Methods and compositions useful for diagnosing inflammatory bowel disease-associated neoplasia

The present invention is directed to methods for diagnosing cancer in a subject. Morphologically normal epithelial cells of the esophagus are assayed for marker expression. Characteristic expression of the markers indicates the presence of cancer or the predisposition to cancer. A panel of eleven markers are particularly good at identifying cancer and the predisposition to cancer.

Esophageal cancer markers

Cancers are extremely heterogeneous in terms of the frequency and types of mutations present in different malignant tumors. Thus, it is likely that uniform clinical treatment is not optimal for all patients, and that the development of individualized therapeutic regimens may be beneficial. Multiple, unique small peptides bind to cell lines derived from different colon adenocarcinomas. Within two hours of contact, the colorectal cancer cells are able to transfer aP radioisotope from the small peptides to cellular proteins; the transfer occurs at a substantially higher rate than in the colorectal cancer cells than in cell lines derived from other cancers or from normal tissues.
