Abstract:
Chemotherapy is one of the most successful strategies for treating cancer. Unfortunately, up to 70 % of cancer survivors develop cognitive impairment during or after chemotherapy, which severely affects their quality of life. We first established a mouse model of CICI and combined bioinformatics, machine learning, and transcriptome sequencing to screen diagnostic genes associated with CICI. Relevant DEGs were screened by differential analysis, and potential biological functions of DEGs were explored by GO and KEGG analysis. WGCNA analysis was then used to find the most relevant modules for CICI. The diagnostic gene Npas4 was screened by combining the three machine learning methods; its diagnostic value was proved by ROC analysis, GSEA analyzed its potential biological function, and then we preliminarily explored the chemicals associated with Npas4. Our study found that Npas4 can be used as an early diagnostic gene for CICI, which provides a theoretical basis for further research.
