Introduction:
To explore the effects of anaerobic glycolysis on Jurkat T cell proliferation and clarify the possible mechanism via transcriptomic analysis.

Material and methods:
The monocarboxylate transporter 1 inhibitor AZD3965 was used to target and block the transmembrane transport of lactate, thereby inhibiting anaerobic glycolysis in Jurkat T cells. Then, genes with differential expression between treated and untreated cells were detected by transcriptomic analysis, and constructs were generated. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses as well as protein–protein interaction (PPI) network analysis were performed to explore the potential mechanism.

Results:
Inhibition of anaerobic glycolysis reduced Jurkat T-cell proliferation. RNA sequencing identified 1723 transcripts that were differentially expressed, including 1460 upregulated genes and 263 downregulated genes. GO functional enrichment analysis showed that the differentially expressed genes were mainly involved in the biological processes of response to unfolded protein, response to topologically incorrect protein, and protein folding. KEGG pathway analysis of differentially expressed genes or hub genes from the PPI network analysis revealed enrichment in the estrogen signaling and PI3K-Akt pathways.

Conclusions:
Anaerobic glycolysis contributes to the regulation of Jurkat T-cell proliferation. The underlying mechanism may involve the estrogen signaling pathway or PI3K-Akt signaling pathway as well as protein metabolism.
