Figure 2. Integrative transcriptome analysis identifies DDIT4 as a candidate target. (A) Venn diagram showing the relationships among DEGs identified from the three comparisons: HDAC4 overexpression versus knockdown (HDAC4 targets); UV-induced senescent versus control HDFs (UV-induced senescence); and H₂O₂-induced senescent versus control HDFs (H₂O₂-induced senescence). Numbers in parentheses, numbers of DEGs. (B) Differential expression patterns of the five overlapping DEGs in the three comparisons (see legend). (C) The mRNA levels of DDIT4, GINS2, and PGAP6 analyzed by RT-PCR (n=5). Data represent the mean ± SE (n = 5, * P < 0.05, ** P <0.01, *** P <0.001). NC: scrambled control.
