  • Publication number: 20180230544
    Abstract: The present disclosure describes methods of determining the risk of developing breast cancer in a subject or determining whether a subject suffers from breast cancer. The methods can comprise detecting the expression level of microRNAs (miRNAs) hsa-miR-186-5p (SEQ ID NO: 77) and/or hsa-miR-409-3p (SEQ ID NO: 178) in a bodily fluid sample obtained from the subject and determining whether it is upregulated or downregulated as compared to a control, wherein the upregulation of hsa-miR-186-5p (SEQ ID NO: 77) and/or downregulation of hsa-miR-409-3p (SEQ ID NO: 178) indicates that the subject has breast cancer or is at risk of developing breast cancers. Also encompassed are methods of prognosis or diagnosis of breast cancer by detecting expression levels of combinations of miRNAs and using a score based on a panel of miRNA markers.

  • Publication number: 20180119222
    Abstract: Present application relates to methods for determining whether a subject has heart failure or is at risk of having heart failure, specifically that of heart failure with reduced left ventricular ejection fraction (HFREF) and a heart failure with preserved left ventricular ejection fraction (HFPEF), comprising determining the level of selected miRNA(s) observed in a sample obtained from the subject and wherein an altered level of the miRNA(s) compared to control indicates that the subject has heart failure or is at risk of developing heart failure. Also encompassed are methods of determining an altered risk of death or disease progression to hospitalization and death based on alteration of selected miRNAs in a sample from the subject and kits thereof.

  • Publication number: 20170233822
    Abstract: Disclosed are methods of determining the likelihood of a subject having or developing a gastric cancer. The methods comprise measuring the expression level of at least one miRNA having at least 90% sequence identity with an miRNA as described herein in a non-cellular biofluid sample obtained from the subject, wherein differential expression of miRNA expression in the sample obtained from the subject, as compared to a control, may be indicative of the subject having gastric cancer and wherein the miRNA may be either an miRNA listed as “up-regulated” or an miRNA listed as “down-regulated”. Also disclosed is a method of determining the likelihood of a subject having or developing a stage of a gastric cancer.

  • Publication number: 20160304884
    Abstract: Described herein is the development of a multi-plasmid system (Compatible Antibiotic-free Multi-Plasmid System, CAMPS) for the expression of one or more nucleic acid sequences of interest in specially engineered host cells and grown in antibiotic-free medium. A panel of compatible plasmids was engineered in which each plasmid comprises an identical origin of replication (Ori) which only differs between plasmids in the loop sequence/s of the RNA I/II region of the Ori. Thus, these plasmids share the same replication mechanism but vary in copy numbers. In order to maintain these multiple plasmids without using antibiotics, multiple conditional essential genes (CEG) from the host genome were grafted into these plasmids. As a result, all of these co-existing plasmids carrying the CEG were maintained in a host where the corresponding CEGs were knocked out from the host's genome during fermentation. Said CAMPS system has broad utility in metabolic engineering and synthetic biology.
