    VGLL1 interacts with common and distinct transcription factors to regulate transcription in tumor cells. (A) Western blot analysis showing relative VGLL1 protein expression either in cell lysates or immunoprecipitated from PANC10.05 and Bewo cells expressing endogenous VGLL1, or PANC1 cells transduced with empty vector (EV) or hVGLL1-MYC plasmid (VGLL1-MYC). Samples without VGLL1 Ab (Beads no Ab) confirmed the specificity of the anti-VGLL1 Ab for IP applications. (B) VGLL1 ChIP-seq analysis was performed on native PANC10.05, BT20, and Bewo tumor cell lines. Homor Motif analysis of the VGLL1 chromatin binding regions revealed several transcription factors (TFs) likely to interact with VGLL1. The Venn diagram shows the common VGLL1 TFs between PANC10.05 (red), BT20 (green) and Bewo (blue) tumor cells. (C–E) ChIP-Atlas was used to compare our results with previously published ChIP-seq data. Each dot represents a different sample (cell line, tissue, etc.) used as a source to pull down individual TFs. Higher enrichment scores indicate higher similarity to the VGLL1 ChIP-seq results. Some samples demonstrated overlap in more than one tumor cell type (black) and others overlapped only with individual tumor cell lines PANC10.05 (red), BT20 (green), Bewo (blue). (F) Table of TFs that were identified in all three tumor cell types. The table contains the TF name and analyzed sample tissue, chromatin motif sequence recognized, percentage of overlapping targets compared to background and p-value. The same color scheme as above indicates the different tumor cell lines analyzed.

    VGLL1 regulates transcription of common and unique genes in different tumor cell types. (A) A representative image of the ChIP-seq chromatin peaks detected for all tumor line samples comparing immunoprecipitated VGLL1 (VGLL1 IP) to input cell lysate. (B) Venn diagram shows the number of merged peaks detected and overlap between the 3 cell lines PANC10.05 (red), BT20 (green) and Bewo (blue). (C) Comparison of merged peak regions showing common and unique VGLL1 binding clusters for each tumor cell line.

(E) Representative images of the ChIP-seq chromatin peaks for each tumor cell line are shown for TRIM6-TRIM34, a read-through transcript upregulated by VGLL1 expression (top), NCOA2, a gene whose expression was upregulated by VGLL1 expression (bottom). Green boxes highlight examples of merged peaks present in all 3 tumor cell types and blue boxes indicate peaks not present in all cell lines. (F) GO-enrichment analysis was performed on VGLL1 ChIP-seq target genes modulated in response to VGLL1 knockdown. Upregulated pathways are shown in orange and downregulated pathways are in purple. .

(E) Representative images of the ChIP-seq chromatin peaks for each tumor cell line are shown for TRIM6-TRIM34, a read-through transcript upregulated by VGLL1 expression (top), NCOA2, a gene whose expression was upregulated by VGLL1 expression (bottom). Green boxes highlight examples of merged peaks present in all 3 tumor cell types and blue boxes indicate peaks not present in all cell lines. (F) GO-enrichment analysis was performed on VGLL1 ChIP-seq target genes modulated in response to VGLL1 knockdown. Upregulated pathways are shown in orange and downregulated pathways are in purple. .
