Levels of tfpia mRNA in a primary knockdown screen of chromatin binding and regulatory proteins. Quantitative real-time PCR showing the fold change of tfpia gene expression in liver and spleen in 23 sets (Set 1–Set 23) of chromatin binding and regulatory protein-knockdowns compared to daily wild-type (WT) controls using one-way ANOVA. The bar graphs represent daily wild-type controls (squared bars), and all knockdowns (open bars and dotted bars) to the right of each wild-type were performed on the same day. Error bars represent mean ± SD. Six fish were used for each set of chromatin binding and regulatory protein-knockdown and control experiments (N = 6). The lines on the top represent a significant difference between wild-type and knockdown sample sets. *** and **** represent p ≤ 0.001 and p ≤ 0.0001, respectively. p-value < 0.05 was considered significant.

Levels of tfpia mRNA in a secondary knockdown screen of chromatin binding and regulatory proteins. Quantitative real-time PCR showing the fold change of tfpia gene expression in liver and spleen in knockdown of 9 chromatin binding and regulatory protein genes, brd7, brd9, ccdc61, ing2, ing3, ing4, supt16h, suz12a, and suz12b, with daily wild-type (WT) controls using one-way ANOVA. The bar graphs represent daily wild-type controls (squared bars), and all knockdowns (open bars and dotted bars) to the right of each wild-type were performed on the same day. Error bars represent mean ± SD. Six fish were used for each of the chromatin binding and regulatory protein gene knockdown and control experiments (N = 6). The lines on the top represent a significant difference between wild-type and knockdown samples. *, **, and *** represent p ≤ 0.05, p ≤ 0.01, and p ≤ 0.001, respectively. p-value < 0.05 was considered significant.

Comparison of time to occlusion of the caudal vein after laser injury between wild-type control 5 dpf larvae and brd7, ing2, ing3, ing4, and suz12b knockdown larvae by one-way ANOVA. The dot plots represent wild-type larvae (closed circles) and the knockdown larvae (closed triangles). Error bars represent mean?±?SD. p-value?

Simultaneous 5-gene knockdowns in adults and larvae. (A) Quantitative real-time PCR showing the fold change of tfpia gene expression in liver and spleen in simultaneous knockdown of 5 chromatin binding and regulatory protein genes, (brd7?+?ing2?+?ing3?+?ing4?+?suz12b) with wild-type (WT) controls using Student?s t test. The bar graphs represent wild-type control (squared bar) and simultaneous 5-gene knockdown (dotted bar). Error bars represent mean?±?SD. Six fish were used for each of the simultaneous 5-gene knockdown and control experiments (N?=?6); (B) Comparison of time to occlusion of the caudal vein after laser injury between wild-type control 5 dpf larvae and simultaneous 5-gene knockdown larvae (brd7?+?ing2?+?ing3?+?ing4?+?suz12b) by Student?s t test. The dot plots represent wild-type larvae (closed circles) and the knockdown larvae (closed triangles). Error bars represent mean?±?SD. For experiments in (A) and (B), p-value?

Treatment of zebrafish larvae and adult with a PRC2 inhibitor, UNC6852. (A) Comparison of time to occlusion of the caudal vein after laser injury between wild-type control 5 dpf larvae and UNC6852-injected larvae by one-way ANOVA. The x-axis represents four different concentrations of the UNC6852 (0.075 mM, 0.15 mM, 0.3 mM and 0.6 mM) used for larval injections. The dot plots represent wild-type larvae (closed circles) and the knockdown larvae (closed triangles). Error bars represent mean?±?SD. 50 larvae each were used in control and UNC6852 injections (N?=?50); (B) Quantitative real-time PCR showing the fold change of tfpia gene expression in liver and spleen for UNC6852-injected adult zebrafish with wild-type control by Student?s t test. The concentration of UNC6852 used for adult injections (0.6 mM) is indicated beneath the bar graph. Error bars represent mean?±?SD. Six fish were used for each of the simultaneous 5-gene knockdown and control experiments (N?=?6). *** and **** represent p???0.001 and p???0.0001, respectively.
