Embodiment 1

[0022] The present invention is described below in conjunction with embodiment.

[0023] 1. Sequence design:

[0024] The siRNA interference sequence is designed for the mIL-17A gene for the synthesis of shRNA, and the siRNA-288 gene sequence is SEQ.No.1.

[0025] 2. Construction of mIL-17A interference vector:

[0026] 2.1 OligoDNA design and synthesis:

[0027] The loop structure in the shRNA template uses TTCAAGAGA to avoid the formation of a termination signal, and the shRNA transcription termination sequence adopts the T6 structure. CACC is added to the 5' end of the sense strand template, which is complementary to the sticky end formed after digestion with BbsI; GATCC is added to the 5' end of the antisense strand template, which is complementary to the sticky end formed after digestion with BamHI; if the shRNA first If a base is not G, add a G after CACC. The mouse IL-17A gene shRNA oligonucleotide sequence (shRNA-288oligoDNA) is shown in Table 1. The design and syn...

Abstract

The invention discloses a sequence siRNA-288 achieving targeted inhibition of a mouse interleukin-17A gene. The sequence number of siRNA-288 is SEQ.No.1. The sequence siRNA-288 achieving targeted inhibition of the mouse interleukin-17A gene has the advantages that it is shown through related experimental results that the sequence siRNA-288 can inhibit expression of the mouse interleukin-17A gene; meanwhile, it is prompted through the related experimental results that the sequence siRNA-288 can be used for inhibiting pathological damage caused by expression of the mouse interleukin-17A gene and can adjust expression of related cell factors, and the purpose of curing a disease is achieved.

Description

technical field [0001] The invention relates to a siRNA-288 sequence targeting to inhibit mouse interleukin 17A. Background technique [0002] Interleukin-17A (interleukin-17A, IL-17A) belongs to the IL-17 cytokine family and is an important pro-inflammatory cytokine discovered in recent years. The IL-17 family currently has 6 members, namely: IL-17A~F, among which IL-17A is commonly called IL-17, which is mainly secreted by Th17 cells. After the IL-17 receptor recognizes the corresponding ligand, it recruits Act1 / CIKS [NFκB activator1, nuclear factor NFκB activator 1, also known as TRAF3 action protein 2 (TRAF3IP2), also known as CIKS (ConnectiontoIKK-complexandSAPK)] to phosphorylate it , activate TRAF6 to transmit signals downstream, regulate the expression of inflammatory molecules and chemotactic molecules, such as: IL-4, IL-5, IL-6, IL-9, IL-13, TGF-β, CXCL1, CCL2, CCL7, Expression of CCL20 and C-reactive protein, etc. IL-17A has a pro-inflammatory effect, induces t...
