Abstract: Disclosed are the nanoparticle and the method for the same, and the preparing method includes steps of mixing polyethylenimine (PEI) with the poly(acrylic acid)-bound iron oxide (PAAIO) to form a PEI-PAAIO polyelectrolyte complex (PEC) and mixing the PEI-PAAIO PEC with genetic material such as plasmid DNA to form the PEI-PAAIO/pDNA magnetic nanoparticle. The PEI-PAAIO/pDNA magnetoplex is highly water dispersible and suitable for long term storage, shows superparamagnetism, low cytotoxicity, high stability and nice transfection efficiency, and thus the PEI-PAAIO PEC can replace PEI as a non-viral gene vector.

Abstract: The present invention discloses a gene carrier and the preparation method thereof. The chondroitin sulfate (CS) is reacted with methacrylic anhydride (MA) to form a chondroitin sulfate-methacrylate (CSMA), which is further covalently bound with 2-(dimethylamino)ethyl methacrylate (DMAEMA) to form the “CM-DM” gene carrier. The novel nonviral and lower cytotoxic gene delivery vector/carrier with the sugar functionality reduced the cytotoxicity of poly(2-dimethylaminoethyl methacrylate) (PDMAEMA), and can successfully deliver plasmid DNA to cancer cells via the caveolae-mediated and CD44-mediated endocytosis mechanisms.

Abstract: The invention provides a nucleotide sequence for Columbidae gender identification, including SEQ ID NO: 9 or a complementary sequence thereof, and also provides a nucleotide primer pair for Columbidae gender identification, including a first primer pair of a first primer designed within the region of the SEQ ID NO: 9 or a complementary sequence thereof, and a P2 primer (SEQ ID NO: 1) or a complementary sequence thereof.

Abstract: The present invention discloses a method of providing anti-oncogenic effects in a subject suffered from colorectal cancer. The present invention also discloses a method for screening an anti-colorectal cancer agent. The present invention further discloses a method of determining the prognosis of a subject with colorectal cancer.

Abstract: The invention provides a method for treating atherosclerosis in a subject in need thereof, including administering an effective amount of microRNA-195 to the subject in need thereof. The microRNA-195 may be packaged in a pharmaceutically acceptable carrier. Moreover, the pharmaceutically acceptable carrier may includes a liposome, lipid particle or viral vector.
