  • Patent number: 11328791
    Abstract: A method for determining a human subject's risk of developing acute kidney injury (AKI) from acute myocardial infarction (AMI) includes: obtaining a blood sample; determining at least two miRNA expression levels therein, which are selected from miR-23a-3p, miR-24-3p, and miR-145-5p expression levels; calculating probability of developing AKI from AMI based on the at least two miRNA expression levels and a logistic regression model; comparing the probability with a predetermined standard; and determining that the human subject is at the risk of developing AKI when the probability is higher than the predetermined standard. A composition may be administered to the human subject for inhibiting development of AKI, if any.

  • Patent number: 9835636
    Abstract: Embodiments relate to serological markers for detecting the colorectal cancer and applications of the serological markers. A phospholipid scramblase1 (PLSCR1), a stomatin-like protein 2 (STOML2) or a transport protein Sec61? (SEC61?) increases expression in the blood at the earlier stage of the colorectal cancer. Detecting the expression of the PLSCR1, STOML2 or SEC61? protein or an induced autoantibody of each protein in a blood sample is used to diagnose the colorectal cancer. Moreover, the serological marker improves the detection efficiency and the sensitivity in detecting the colorectal cancer and is used to predict the prognosis. The serological markers are applied in preparing a detection device or inhibiting the growth of the colorectal cancer cells.

    Abstract: A urinary biomarker for urinary tract cancers and applications of the same are revealed. TACSTD2 is used as a non-invasive urinary biomarker for urinary tract cancers due to a feature that the TACSTD2 protein is increased significantly in urine of patients with urinary tract cancers. The quantitative urinary biomarker shows high specificity and high sensitivity for urinary tract cancer detection. Besides increasing screening efficiency, early diagnosis and early treatment of urinary tract cancers, the biomarker can also be used to assess malignancy of urinary tract cancers and monitor tumor progression for determining optimal treatment against the disease and improving the treatment results.

  • Publication number: 20120295288
    Abstract: UL16 binding protein 2 (ULBP2) is a protein overexpressed in pancreatic cancer tissues, and the ULBP2 levels are significantly higher in pancreatic cancer patients than those in healthy controls. This invention provides a method to detect pancreatic cancer using ULBP2 as a serological marker. The combination of ULBP2 and CA19-9 promotes the efficacy of pancreatic cancer detection. When measuring the blood ULBP2 levels in patients with other cancer types, including colorectal carcinoma, nasopharyngeal carcinoma and gastric cancer illustrates the blood ULBP2 levels are higher in patients with pancreatic cancer than other cancer types.
