Abstract

The invention discloses a rule weight distribution siRNA design method based on grid search, and relates to the technical field of bioinformatics. The method comprises the following steps: S1, training siRNA data to obtain siRNA design rule weights; and S2, based on the obtained siRNA design rule weights, screening out siRNA with high silence efficiency from the candidate siRNA set. According to the method, each rule is differentially treated according to different weights, and based on the multi-rule design of different weights, all rules can be prevented from being treated according to the same importance degree, important rules in the rules can be highlighted, effective siRNA and ineffective siRNA can be distinguished, and the efficiency of candidate siRNA sequences can be quantitatively predicted.

Description

technical field [0001] The present invention relates to the technical field of bioinformatics, in particular to a grid search-based method for designing siRNA with regular weight distribution. Background technique [0002] RNA interference (RNA interference, RNAi) is a post-transcriptional gene silencing phenomenon induced by short double-stranded RNA (Small interfering RNA, siRNA). Functional exploration, gene expression regulation mechanism and other fields have accelerated the research of functional genomics, and also promoted the research of gene therapy and other related fields. [0003] siRNA is a double-stranded RNA composed of 20 to 27 base pairs. Its efficiency is affected by many factors such as the target gene mRNA sequence and its own sequence. One of the key factors is the siRNA sequence design. A large number of studies have proved that siRNA designed for the same target mRNA The effects vary greatly. How to screen siRNAs for efficient silencing of target gen...
