Embodiment 2

[0102] Example 2 Real-time fluorescent quantitative RT-PCR method to detect the silencing efficiency of RBM17 gene

[0103] The glioma U251 cells in the logarithmic growth phase were trypsinized to make a cell suspension (the number of cells was about 5×10 4 / ml) were inoculated in a 6-well plate and cultured until the cell confluency reached about 30%. According to the multiplicity of infection (MOI, U251:5) value, an appropriate amount of the virus prepared in Example 1 was added, the culture medium was replaced after 24 hours of cultivation, and the cells were collected after the infection time reached 5 days. Total RNA was extracted according to the instruction manual of Invitrogen's Trizol. According to the M-MLV instruction manual of Promega Company, RNA was reverse-transcribed to obtain cDNA (see Table 7 for the reverse transcription reaction system, react at 42° C. for 1 h, and then bathe in a water bath at 70° C. for 10 min to inactivate reverse transcriptase).

Embodiment 3

[0110] Example 3 Detection of proliferation ability of tumor cells infected with RBM17-siRNA lentivirus

[0111] The glioma U251 cells in the logarithmic growth phase were trypsinized to make a cell suspension (the number of cells was about 5×10 4 / ml) were inoculated in a 6-well plate and cultured until the cell confluency reached about 30%. According to the multiplicity of infection (MOI, U251:5), an appropriate amount of virus was added, and the culture medium was replaced after 24 hours of culture. After the infection time reached 5 days, the cells of each experimental group in the logarithmic growth phase were collected. The complete medium was resuspended into a cell suspension (2×10 4 / ml), inoculate a 96-well plate at a cell density of about 2000 / well. 5 replicate wells in each group, 100 μl per well. After laying the board, place at 37°C, 5% CO 2 Incubator cultivation. From the second day after plating, the plate was detected and read once a day with a Cellomics ...

Abstract

The invention discloses uses and related drugs of a human RBM17 gene. The invention discloses the uses of the human RBM17 gene in tumor therapy, tumor diagnosis and drug preparation. The invention further discloses a human RBM17 gene small-molecular interference RNA, a human RBM17 gene interference nucleic acid construction body and a human RBM17 gene interference slow virus and uses thereof. The siRNA or the siRNA sequence-containing nucleic acid construction body and slow virus provided by the invention, especially the slow virus, can specifically inhibit expression of the human RBM17 gene, can efficiently infect target cells, efficiently inhibit expression of the RBM17 gene in the target cells, inhibit the growth of the tumor cells, promote the apoptosis of the tumor cells and have important significance in tumor therapy.

Description

technical field [0001] The present invention relates to the field of biotechnology, and more specifically relates to the use of human RBM17 gene and related medicines. Background technique [0002] RNA interference (RNAi) is short double-stranded RNA (dsRNA) composed of nucleotides for post-transcriptional gene silencing. It can efficiently and specifically block the expression of a specific gene in the body, leading to its degradation, thereby causing the silencing of a specific gene in the organism, and causing the cells to show the absence of a certain gene phenotype. It is a commonly used research gene emerging in recent years. Functional, laboratory techniques for finding cures for disease. Studies have shown that double-stranded RNA with a length of 21-23nt can specifically cause RNAi at the transcriptional and post-transcriptional levels (TuschlT, ZamorePD, SharpPA, BartelDP. RNAi: double-stranded RNA directs the ATP-dependent cleavage of mRNA at 21to23nucleotide int...
