  • Publication number: 20220265723
    Abstract: Described herein are methods for transfecting mesenchymal stem cells (MSCs) with a nucleic acid construct using a cationic polymer, a first reagent capable of redirecting endocytosed nucleic acids from intracellular acidic compartments, and a second agent capable of stabilizing a microtubular network of the MSCs. The methods are free of virus-based transfection vehicle materials and the transfected MSCs have substantially unchanged multipotent phenotype. In certain embodiments, the transfected MSCs express functional genes comprising suicide gene, such as cytosine deaminase or uracil phosphoribosyltransferase. Also described are methods for the treatment of diseases, such as cancer, using such transfected cells in combination with 5FC, 5FU, GCV, as well as kits and composition relating thereof.

  • Publication number: 20220119823
    Abstract: The invention provides, inter alia, a nucleic acid (e.g. expression vector) that comprises at least a first coding sequence and a second coding sequence. Each conding sequence is under the control of an inducible promoter of defined strength. Different promoters can have different strengths. Each promoter is responsive to the same inducer. The invention also provides: methods of expressing coding regions, methods of making a product of a multi-enzyme pathway, and methods of optimizing the yield of a product of a multi-enzyme metabolic pathway using the nucleic acids provided by the invention. Also disclosed is a method of non-enzymatic gene cloning useful for practicing the invention.

  • Publication number: 20220081722
    Abstract: We describe a method of diagnosing a gastric cancer. The method may include detecting the expression level of an miRNA in a sample of or from an individual. The expression level of the miRNA may be detected in an extracellular vesicle (EV) from the sample. The miRNA may be selected from the group consisting of: hsa-miR-484, hsa-miR-186-5p, hsa-miR-142-5p, hsa-miR-320d, hsa-miR-320a, hsa-miR-320b and hsa-miR-17-5p. The method may be such that an altered expression level of the miRNA as compared to the expression level of the miRNA in an EV in or of an individual known not to be suffering from gastric cancer indicates that the individual is suffering, or is likely to be suffering, from gastric cancer.

  • Publication number: 20220033905
    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.

  • Patent number: 10767230
    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.
