Method for detecting DAN methyltransferase activity based on strand displacement amplification and DNAzyme amplification

The invention relates to a method for detecting DAN methyltransferase activity based on strand displacement amplification and DNAzyme amplification. A three-function double-stranded DNA probe is designed. Methylation happening to the three-function double-stranded DNA probe is specifically recognized through DAN methyltransferase. Remaining non-methylated double-stranded DNA is specifically cut through HpaII restriction enzymes, methylated double-stranded DNA triggers a strand displacement reaction, a large amount of 8-17 DNAzyme is released, the 8-17 DNAzyme catalyzes cutting of a large number of hairpin-line molecular beacon substrates, and remarkable fluorescent enhancement is triggered. The method can sensitively detect the DAN methyltransferase activity, and the detection limit is 0.0082 U / mL. The method has potential application in research of influences of anti-cancer drugs on DAN methyltransferase activity inhibition and screening of DAN methyltransferase inhibitors.

Umbilical cord blood Treg cell in-vitro amplification method based on trophoblastic cells and application

The invention discloses an umbilical cord blood Treg cell in-vitro amplification method based on trophoblastic cells and application. The specific technical method comprises the steps that firstly, umbilical cord Wharton's jelly mesenchymal stem cells are adopted as the trophoblastic cells to induce preliminary proliferation of Treg cells in umbilical cord blood mononuclear cells; then, pure Tregcells are obtained through magnetic bead sorting; and finally, the Treg cells are stimulated to be rapidly amplified by using optimized amplification factors. According to the amplification method, human AB plasma, IL-2, rapamycin, an RARA agonist and a DNA methyltransferase inhibitor are used as the optimized amplification factors, and a large number of umbilical cord blood Treg cells with high purity and high activity can be prepared within two weeks. Umbilical cord blood is used as a raw material for Treg cell amplification, batch preparation can be achieved, and Treg cell quality fluctuation caused by individual differences of samples can be reduced. The umbilical cord blood Treg cells have low immunogenicity and can be used as universal cells for clinical research, such as autoimmunediseases, graft-versus-host diseases and the like.

Application of vanillin in preparation of nicotinamide-N-methyltransferase inhibitor

The invention discloses an application of vanillin in preparation of a nicotinamide-N-methyltransferase inhibitor. The inhibitor is prepared from traditional Chinese medicine monomer vanillin and pharmaceutically acceptable auxiliary materials. According to the invention, proliferation of various colorectal cancer cell strains is inhibited by inhibiting the expression of NNMT and enzyme activity in vitro and vivo, and an anti-tumor effect is achieved. Studies show that vanillin can weaken the drug resistance of colorectal cancer cell strains to 5-FU caused by high expression of NNMT in vitro,so that the chemotherapy sensitivity is enhanced; the apoptosis of the colorectal cancer cell strains with high expression of NNMT is increased by inducing ROS production and mitochondrial damage in cells; and the inhibitory effect of 5-fluorouracil on tumor proliferation and the apoptosis rate can be improved, so as to enhance the chemotherapy effect. The vanillin can be used as an NNMT inhibitorfor preparing anti-colorectal cancer drugs or adjuvant chemotherapy drugs, and has a good application prospect.
