a Genes differentially expressed in IMR90 cells upon treatment with cNSF-HA or fNSF-HA (HA polymer length-dependent genes). Cells were pre-incubated for 6 h with 20 μg/ml cNSF-HA, fNSF-HA, or PBS and then HA was removed and cells were exposed to 200 μM tBHP for 1 h. Cells were collected 6 h after starting the tBHP-treatment. b Enrichment of GO Term, Reactome pathway, and transcription factor protein-protein interactions (PPIs) in the HA polymer length-dependent genes. c, d Enrichment of transcription factor binding sites (TFBS) in the HA polymer length-dependent genes. White bars represents the enrichment of TFBS in all HA polymer length-dependent genes. Gray bars represents the enrichment of TFBS in HA polymer length-dependent genes that are involved in the transcriptional regulation by p53 or encoding p53-interacting proteins. Black bars represents the enrichment of TFBS in HA polymer length-dependent p53 target genes. e Differential expression levels of the HA polymer length-dependent genes (defined in the presence of tBHP) in IMR90 cells incubated for 6 h with 20 μg/ml cNSF-HA, fNSF-HA, or PBS. f The violin plot represents the distribution of p-values of a two-tailed t-test comparing the gene expression levels of the HA polymer length-dependent genes and HA-polymer length-independent genes (defined in the presence of tBHP) between cNSF-HA- and fNSF-HA-incubated IMR90 cells. Cells were incubated for 6 h with 20 μg/ml cNSF-HA or fNSF-HA without further tBHP-treatment. g Differential expression levels of the HA polymer length-dependent genes (defined in the presence of tBHP) in control and CD44-overexpressing IMR90 cells incubated for 6 h with 20 μg/ml cNSF-HA or PBS.
