Abstract:
Beryllium and its compounds can cause pulmonary interstitial fibrosis through mechanisms that are not yet clear. Long non-coding RNA (lncRNA) is implicated in various diseases. The molecular toxicity of beryllium sulfate (BeSO4) was investigated through the RNA-seq analysis of the lncRNA and mRNA whole-transcriptome of BeSO4-treated 16HBE cells. A total of 1014 lncRNAs (535 upregulated and 479 downregulated) and 4035 mRNAs (2224 upregulated and 1811 downregulated) were found to be significantly dysregulated (|logFC| ≥> 2.0, p < 0.05) in the BeSO4-treated groups when compared with the control group. Five differentially expressed lncRNAs and mRNAs were verified by qRT-PCR. KEGG analysis showed that lncRNA regulates the ECM receiver interaction and PI3K/AKT signaling pathways, etc. In addition, H19:17, lnc-C5orf13-1:1, lnc-CRYAA-17:1, lnc-VSTM5-1:11, and lnc-THSD7A-7:1 may regulate BeSO4-induced 16HBE cytotoxicity through ceRNA mechanism. The results of this study will provide some theoretical support for the study of the toxic mechanism of beryllium and its compounds.
