Article Title: ETV4 Facilitates Cell Cycle Progression in Pancreatic Cells through Transcriptional Regulation of Cyclin D1

doi: 10.1158/1541-7786.MCR-17-0219

Figure Lengend Snippet: (A) Cyclin D1 cDNA construct (pCMV6-CCND1) was transfected in ETV4-silenced Colo357 and ASPC1 cells for its overexpression and confirmed by immunoblot analyses. (B) After 48 h of transfection, cells further transfected with Cyclin D1 promoter reporter construct and transcriptional activity of Cyclin D1 was examined. Data are presented as normalized relative luciferase activity (mean ± SD; n = 3, *p < 0.05). (C-D) Overexpression of cyclin D1 in ETV4-silenced cells rescued the inhibitory effect of ETV4-silencing on (C) growth and (D) cell cycle progression of PC cells.

Figure Lengend Snippet: ( a , b ) CCNE1 (G1-phase) and PCNA (S-phase) immunostaining of E14.5 and E17.5 NPCs treated for 24 h with BMP7, TAK1 and JNK inhibitors. Graphs show the percentage of G1, G1-S and S-phase cells per condition. Three biological replicates analysed per condition ( n =3). Error bars represent s.d. ** P <0.005 and ** P <0.001, Student's t -test. ( c , d ) RT–qPCR of JUN and MYC targets in E14.5 and E17.5 NPCs treated with vehicle, BMP7, TAK1 and JNK inhibitors for 2 h. Error bars indicate s.d. Three biological replicates analysed per condition ( n =3). ( e , f ) RT–qPCR of JUN and MYC targets on NPCs isolated from E14.5 Jun het , Jun NP C and E17.5 Tak1 het , Tak1 NPC kidneys. Error bars represent s.d. Two biological replicates analysed per genotype ( n =2). ( g , h ) CCND1 and CCNE1 immunostaining in E14.5 Jun het , Jun NPC and E17.5 Tak1 C-WT , Tak1 C-NPC kidneys. Scale bars, 100 and 150 μM. Quantitation of CCND1+ and CCNE1+ cells per cap mesenchyme (yellow arrows) was calculated by scoring at least 30 random cap mesenchymes per kidney section per genotype for a total of 5 sections from each experimental group. Error bars indicate mean (s.d.). ** P <0.005 and ** P <0.001, Student's t -test. ( i ) Model for BMP7-TAK1-JNK-JUN pathway regulation of NPC self-renewal in early (E14.5) and later (E17.5) phases of nephrogenesis. CD, collecting duct; CM, cap mesenchyme.

Scale bars, 50 μM. Graphs show the percentage of EdU+,pHH3+ cells and G1, G1-S and S-phase cells in each condition. Error bars represent mean (s.d.). ** P <0.005 and P <0.001 (Student's t -test). Two to three biological replicates analysed per condition ( n =2 in a ) and ( n =3 in b ) ( c , d ) RT–qPCR of cell cycle genes ( Ccnd1 and Myc ), Jun and Fos in NPCs stimulated with vehicle, BMP7, FGF9 or BMP7+FGF9 for 2 h. Error bars represent s.d. Three biological replicates analysed per condition, n =3. ( e , f ) pJUN and pFOS immunoblot of NPCs stimulated with vehicle, BMP7, FGF9 or BMP7+FGF9 for 20 min. Graph shows the relative density of pJUN and pFOS normalized to β-tubulin in each condition . ( g – i ) Bars in the graphs represent the average fold change in luciferase activity of 3xAP1-Luc, CCND1-Luc and CCND1 ΔAP-1 -Luc in NPCs stimulated with BMP7 and FGF9 relative to vehicle treatment for 24 h. Three biological replicates analysed per condition ( n =3). Error bars represent s.d. ** P <0.005, NS, not significant P >0.05, Student's t -test.
