Embodiment 1

[0043] Example 1. The establishment and result analysis of the method for evaluating the toxicity mechanism of PFOS using transcriptomics

[0044] 1. Acquisition of transcriptomics data

[0045] 1.1 PFOS treatment

[0046] The experiments described below consisted of three replicates.

[0047] (1) Select 6-8 week-old Sprague-Dawley rats (purchased from Beijing Weitong Lihua Experimental Animal Technology Co., Ltd.), 8 in total, 4 males and 4 males. The 8 rats had the same or similar date of birth and similar body weight among the same sex. The age (6 weeks for male rats and 6 weeks for female rats) and body weight (281±13g for male rats and 190±6g for female rats) were recorded. Eight rats were randomly divided into two groups, namely the control group and the PFOS exposure group, with two males and two males in each group. Rats in the control group and the PFOS-exposed group should not be housed in one cage.

[0048] (2) Rats were fed for one week before the experiment. ...

Abstract

The invention discloses a method for screening a PFOS toxicity hub gene and a key signal channel by applying transcriptomics. According to the method, firstly, a blank control group and a PFOS exposure group of experimental animals are set and processed to obtain a biological sample, RNA of the obtained biological sample is extracted, transcriptomics data of the biological sample are obtained through a high-throughput sequencer, the the obtained sequencing data is subjected to bioinformatics analysis comprising differential gene GO enrichment analysis, KEGG pathway enrichment analysis, protein interaction network analysis and GSEA analysis, and finally the PFOS toxic hub gene and key signal pathway results are obtained through screening. By applying the method provided by the invention, help can be provided for identifying the serious influence of the PFOS on animals or human beings and / or the toxicity mechanism of the PFOS on the animals or human beings and developing related drugs aiming at the toxicity of the PFOS.

Description

technical field [0001] The invention relates to the field of bioinformatics, in particular to a method for screening pivotal genes and key signaling pathways of perfluorooctane sulfonic acid toxicity by using transcriptomics. Background technique [0002] Perfluorooctane Sulfonate (PFOS) has been widely used in civil and industrial products, such as surfactants, fireproof coatings and photoresists due to its extremely low surface tension and unique physical properties of hydrophobicity and oleophobicity Wait. However, in view of the characteristics of such compounds as toxicity, environmental persistence, bioaccumulation and long-distance migration, the United Nations Environment Program listed PFOS and its salts and precursor compounds as new persistent substances in the "Stockholm Convention" in 2009. Organic Pollutants. Studies have shown that PFOS exhibits various toxic effects on animals, such as liver toxicity, testicular toxicity, pancreatic toxicity, neurotoxicity,...
