E2F1 and E2F4 were downregulated by OTA exposure. ( A ) E2F1 and E2F4 were significantly downregulated following 100 nM OTA exposure according to RNA-sequencing data in both cell lines, while E2F7 was found to be upregulated only in HEK293-T cells. Due to the consistent results between the two cell lines, the expression of E2F1 and E2F4 only was verified by RT-qPCR ( B ) and Western blot ( C ) (mean ± SD, * p < 0.05, N = 3).

Article Snippet: CDKN1A/p21 (Cell Signaling Technology, cat. no. 2946, Frankfurt, Germany), CDK2 (Cell Signaling Technology, cat. no. 2546), and E2F4 (R&D, cat. no.

In silico analysis of LTBP4 promoter sites identified a highly methylated binding site for GATA1 in the LTBP4L promoter of OE33 and KYSE180 cells. Highly methylated binding sites for SP1 and E2F4 are found in the LTBP4S promoter of both cell lines. A binding site for SMAD3 was identified nearby. The methylation status was analyzed by clonal bisulfite sequencing and at least ten clones were sequenced for each cell line. The percentage of methylation is visualized as pie chart. Exons are illustrated by black boxes and LTBP4S and LTBP4L promoters by red lines. The translation start sites are indicated (ATG). The dashed lines represent alternative splicing of LTBP4.

Cells were also co-transfected with different concentrations of A) a Gata1 expression vector, B) a SP1 expression vector, C) a SMAD3 expression vector or D) an E2F4 expression vector. After 24 h cells were lysed and luciferase activities were determined. Experiments were repeated at least 3 times and the mean value was calculated. Data are presented ± standard deviation.

The transactivation and DNA binding domains of E2F4 are required for its function in mouse ES cells. a Schematic of the design of E2F4 mutant constructs. All constructs were fused C-terminal to a GFP tag. Wild-type (WT) E2F4 contains a DNA binding domain (DBD), a dual nuclear export signal (NES), a DP dimerization domain, a transactivation domain, and an RB family/pocket proteins binding domain (PPBD). GFP-DBD contains three point mutations that make contacts with the E2F consensus binding motif and the DP dimerization partners. GFP-T360 is a truncation mutant that lacks the last 50 amino acid residues, inactivating the transactivation domain. b Quantification of endogenous and exogenous E2F4 expression by immunoassay (from fluorescence units) in WT (gray) and E2F4KO (KO, green) cells ( n = 2 biological replicates with 1 WT and 1 E2F4KO clone). c Quantification of colony size by AP staining (unpaired t-test was performed with all individual data points from n = 2 biological replicates with 2 WT and 2 E2F4KO clones in each replicate) and d Total number of cells per well in 6-well plates one week after plating at low density (unpaired t-test was performed with all individual data points from n = 4 biological replicates with 2 WT and 2 E2F4KO clones in each replicate). e RT-qPCR analysis of E2F4 targets and canonical cell cycle genes.
