Embodiment 1

[0020] Example 1 RNAi screening of kinase genes essential for the growth of liver cancer cells within the scope of the whole kinase group

[0021] A library of siRNAs targeting all kinases and kinase-related genes on the human genome was obtained commercially (Stealth TM RNAi Human Kinase Collection, Invitrogen, Catalog no. 12938-200). Stealth per set TM The RNAi Collection consists of several 96-well plates. Stealth by 2 nmoles TM RNAi was dissolved in 100 μl of 1X RNA annealing / dilution solution (10 mM Tris-HCl, pH 8.0; 20 mM NaCl; 1 mM EDTA, pH 8.0) to a final concentration of 20 μM.

[0022] Use CellCounting Kit-8 (cell viability detection kit, referred to as CCK-8) to measure cell viability, the experimental steps are as follows figure 1 As shown, the absorbance is measured with a BioTek microplate reader in the United States to generate raw cell activity data. The raw data undergoes steps such as standardization, data correction, and Z value evaluation, such as ...

Embodiment 2

[0023] Example 2 RNA interference PDK3 gene inhibits the growth of liver cancer cells

[0024] 48 hours after the constructed plasmid pSUPER was transfected into liver cancer cells, the cell line RNA was extracted, and the effect of RNA interference was identified by quantitative PCR. For transfection, the cells were re-seeded in a 10cm large plate for culture, and neomycin G418 was added to the culture medium for selection and culture for 4 to 6 weeks. The culture medium was removed, rinsed twice with 1×PBS, stained with crystal violet, and photographed for counting.

Embodiment 3

[0025] Example 3 Immunoassay

[0026] 1. Acquisition of antigenic protein

[0027] Obtain the cDNA sequence of human PDK3 gene from Genebank in the United States, obtain the coding frame by PCR amplification, insert it into a prokaryotic or eukaryotic expression vector, express PDK3 protein, and purify the protein according to the purification system of genetic engineering expression products.

[0028] 2. Antibody Preparation

[0029] Antibodies can be prepared in several ways:

[0030] (1) Cell fusion method: immunize animals (including rabbits, goats, etc.) with the PDK3 protein prepared above, obtain spleen cells, fuse with myeloma cells, and prepare monoclonal antibodies according to conventional monoclonal antibody preparation techniques.

[0031] (2) Using the phage surface display library, cloning the spleen IgG variable region of the immunized animal and expressing it into a genetically engineered monoclonal antibody.

[0032] (3) Using the purified protein to immun...

Abstract

The invention discloses application of a PDK3 gene and its expression product in preparing medicaments for treating liver cancer. The PDK3 gene and its expression product of the invention can be taken as a target gene for preparing medicaments treating liver cancer, thus providing a new approach for liver cancer treatment.

Description

technical field [0001] The invention relates to the technical field of gene therapy, in particular to the application of a PDK3 gene and its expression product. Background technique [0002] The treatment of liver cancer has made great progress in the past 20 years, and some local non-surgical treatment options have emerged. For example, transcatheter arterial chemoembolization (TACE) is an important method for the treatment of advanced liver cancer, which can benefit more than 90% of liver cancer patients; percutaneous intratumoral ethanol therapy (PEI) is also a commonly used local chemotherapy method, it has a certain curative effect on liver cancer and portal vein tumor thrombus whose tumor diameter is less than 3 cm. However, since the current chemotherapy drugs for liver cancer basically follow the treatment drugs for other tumors, the pertinence is poor. Therefore, the overall curative effect is not good. specificity and effectiveness. [0003] Protein kinase is en...
