The composition and expression levels of transcription factors in the regeneration of A. japonicus after exposure to TBBPA. (A) The transcription factors found in the transcriptome of the regenerated intestines. (B) The DEGs of transcript factors in the regenerated intestines after exposure to TBBPA. (C) The expression levels of gene-BSL78_08697 (C2H2 family), gene-BSL78_00076 (HMG family), gene-BSL78_28882 (STE_STE20-Fray family), gene-BSL78_27935 (C2H2 family), and gene-BSL78_29739 (TKL-Pl-4 family) in the regeneration after exposure to TBBPA. TBBPA-0, TBBPA-3, and TBBPA-5 means the 0 nmol/L TBBPA exposure group, the 3 nmol/L TBBPA exposure group, and the 5 nmol/L TBBPA exposure group, respectively. * Means p < 0.05.
