  • Patent number: 10774386
    Abstract: Provided are non-small cell lung cancer markers and the use thereof in diagnosing and monitoring diseases in vitro. The non-small cell lung cancer markers include at least one of 26 selected detectable mature microRNAs existing stably in human serum or plasma. Also provided are probe combinations, a kit and a biochip for detecting the non-small cell lung cancer markers. The invention further provides a method for detecting the said lung cancer markers. The method in the present invention enables extensive detection spectrum, high sensitivity, low cost, convenient sample taking and preservation. The method can be applied in the general survey of disease, solves problems of low specificity and sensitivity encountered with previous single markers, and increases significantly the clinical detection rate of diseases. The methods provide an effective means for diagnosing diseases at an early stage.

  • Patent number: 9821009
    Abstract: 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.

  • Publication number: 20110117565
    Abstract: The present invention provides non-small cell lung cancer markers and the use thereof. The non-small cell lung cancer markers in the present invention include at least one of the 26 selected detectable mature microRNAs existing stably in human serum or plasma. The invention also provides a probe combination, kit and biochip for detecting the non-small cell lung cancer markers. The invention further provides a method for detecting microRNAs in the serum of lung cancer patients. By detecting the variations of microRNAs in the serum of lung cancer patients, the disease can be diagnosed in vitro; the progression course of the disease can be predicted; the occurrence of complications, the rate of relapse and the prognosis of the disease can be monitored; the drug efficacy and therapeutic effects can be analyzed. The method in the present invention enables extensive detection spectrum, high sensitivity, low cost, convenient sample taking and preservation.
