Background
Osteosarcoma is a common primary bone malignancy, which occurs in children and adolescents, and the current standard treatment is a combination of neoadjuvant chemotherapy-surgery-adjuvant chemotherapy based on a regimen comprising doxorubicin, cisplatin, and large doses of methotrexate (MAP regimen). Although perioperative chemotherapy greatly improves the 5-year survival rate and the limb protection rate of patients with osteosarcoma, the 5-year survival rate of patients with limited period is 60% -70%, the survival benefit brought by chemotherapy does not obtain further breakthrough in more than 40 years. 10% -15% of osteosarcoma patients are accompanied with metastasis at the initial diagnosis, the most common metastasis site is lung, the survival rate of the patients with metastatic or recurrent osteosarcoma is only 20% in 5 years, the prognosis is extremely poor, and improvement is needed in the current state of treatment.

Detailed Description
The raw materials and equipment used in the invention are all known products and are obtained by purchasing commercial products.
143b cells: osteosarcoma cells purchased from the biological technology Co.Ltd
Lipofectamine ™ 3000 transfection reagent: eukaryotic transfection reagents were purchased from thermosusher under the designation L3000001.
Annexin V-APC/PI apoptosis detection kit: apoptosis was detected. Propidium Iodide (PI) is a nucleic acid dye that does not penetrate intact cell membranes, but cells in the middle and late stages of apoptosis and dead cells due to increased cell membrane permeability, PI can penetrate cell membranes and stain the nucleus with red. By matching Annexin V to PI, cells at different stages of apoptosis can be distinguished. The product number KGA1030, the Yu Kaiji organism was purchased.
Example 1,NAT9Effects of knockout on osteosarcoma
1. Experimental method
(one)NAT9Knock-out
143b Cell line was inoculated in an e-plate96 well plate (DMEM medium) and placed in an RTCA Cell dynamic detector, and sh-NAT9 and transfection reagent were added when the CI (Cell Index, indicator of Cell growth) was 1, to add universal negative control NC-treated cells as controls.
sh-NAT9:
sense CCACGAGTGGATGAAATCA (SEQ ID NO.1)
antisense GGTGCTCACCTACTTTAGT(SEQ ID NO.2)。
shNC group: is a negative transfection control group.
(II) inspection method
Apoptosis: 143b cell knockdownNAT9 After 48h, the cell suspension was collected. The cell suspension was centrifuged for 5 min at 250 g, the supernatant was aspirated, washed once with PBS, centrifuged for 5 min at 250 g, and the collected cell pellet was used for staining. After resuspension of the cells with 500. Mu.L of PBS buffer (Punuocele, cat. PB 180327), 5. Mu.L of Annexin V was added and gently blown up, followed by addition of 5. Mu.L of PIHomogenizing; incubate at room temperature for 10 min under light protection, and perform detection analysis using a flow analyser (model: cytoflex manufacturer: beckman) instrument.
Cell migration: serum-free DMEM 200. Mu.L and 2X 10 were added to the Transwell chamber 4 143b cells, 600. Mu.L of 10% serum DMEM was added to the lower chamber at 5% CO 2 The cell incubator was incubated for 24 hours, the cells passing through the membrane pores were stained with 1% crystal violet in a 4% paraformaldehyde fixed cell, photographed under a normal microscope, the number of perforated cells calculated, and the cell mobility calculated.
2. Experimental results
NAT9The result of the gene expression ratio is shown in FIG. 1, the lower the gene expression ratio is, the higher the knocking down efficiency is,NAT9the knockdown efficiency was 64%.
