20140121133 | SERUM/PLASMA MicroRNAs AND USES THEREOF - This invention provides a combination of microRNAs for evaluating the physiological and/or pathological condition of a subject, wherein the combination comprises all detectable microRNAs stably existing in the serum/plasma of a subject; and a method for evaluating the physiological and/or pathological condition of a subject, wherein the method includes determining all detectable microRNAs stably existing in the serum/plasma of a subject; and a kit for evaluating the physiological and/or pathological condition of a subject, wherein the kit contains the tools for determining all detectable microRNAs that stably existing in the serum/plasma of a subject; and a biochip for evaluating the physiological and/or pathological condition of a subject, wherein the biochip contains the components for determining all detectable microRNAs stably existing in the serum/plasma of a subject. The aforementioned combination, method, kit and biochip can be used for diagnosis as well as differentially diagnosis of diseases including various tumors; various acute/chronic infectious diseases, e.g. viral diseases such as viral influenza, viral hepatitis, AIDS, SARS, bacterial diseases such as tuberculosis, bacterial pneumonia, and other acute/chronic infectious diseases caused by various pathogenic microorganisms; other acute/chronic diseases such as diseases of respiratory system, diseases of immune system, diseases of blood and hematopoietic system, diseases of circulatory system such as cardio-cerebrovascular diseases, metabolic diseases of endocrine system, diseases of digestive system, diseases of nervous system, diseases of urinary system, diseases of reproductive system and diseases of locomotor system, prediction of complications occurrence and malignant diseases relapse, evaluation of therapeutic effects, screening of pharmaceutical active ingredients, assessment of drug efficacy as well as forensic authentication and prohibited drug inspection and the like, possessing a number of advantages such as extensive detection spectrum, high sensitivity, low cost, convenience for sampling, ease for sample preservation, etc. The said method can be widely used in work related to general survey of diseases and so on, improve the low-specificity and low-sensitivity caused by individual differences which single markers are difficult to overcome, significantly increasing the clinical detection rate of diseases, all of which make it become an effective means for diagnosing diseases in an early phase. | 05-01-2014 |
20130078225 | Method for Modulating MicroRNA Content in Living Beings and the Use Thereof - The present invention relates to a method for modulating miRNA content in living beings and the use thereof, whereof the miRNAs are delivered initiatively and selectively by microparticles/MVs/exosomes to the circulatory system and target cells/tissues to perform various functions. The invention provides a novel combination of molecules that mediates the inter-cellular communication: the miRNAs secreted by cells through cellular MVs. Meanwhile, the present invention also provides a method for preparing cellular MVs entrapping certain miRNAs, and, according to the regulation and modification of gene expression in cells and tissues with the miRNA-entrapping cellular MVs, provides a novel method for modulating miRNA content in living beings, which is effective and adoptable to all cell types. | 03-28-2013 |
