Figure Lengend Snippet: a The 3D spheroid formation assay. The cells transfected with siEHMT2 and siCont were loaded onto ULA plates and incubated for 48 h. The cells were photographed under a microscope each day. Scale bar, 500 μm. b Western blot analysis of cells after EHMT2 knockdown using anti-PARP and anti-ACTB antibodies. ACTB was used as the internal control in A498 cell. c RT‒qPCR analysis of EHMT2 and DDIT3 expression after EHMT2 knockdown. The data are presented as the means ± s.d. of three independent experiments. P values were calculated using Student’s t -tests (* P < 0.05, ** P < 0.01, *** P < 0.001). d The 3D spheroid formation assay. Cells cotransfected with siEHMT2 and siDDIT3 were loaded onto ULA plates and incubated for 48 h. The cells were photographed under a microscope each day. Scale bar, 500 μm. e Western blot analysis of cells cotransfected with siEHMT2 and siDDIT3 using anti-PARP and anti-ACTB antibodies. ACTB was used as the internal control in A498 cell. f RT‒qPCR analysis of EHMT2 and DDIT3 expression in cells cotransfected with siEHMT2 and siDDIT3. The data are presented as the means ± s.d. of three independent experiments. P values were calculated using Student’s t -tests (** P < 0.01, *** P < 0.001). g The 3D spheroid formation assay. After BIX was added to ULA plates, the cells were incubated for 48 h. The cells were then photographed under a microscope each day. Scale bar, 500 μm. h Western blot analysis of cells treated with BIX using anti-PARP and anti-ACTB antibodies. ACTB was used as the internal control in A498 cell. i RT‒qPCR analysis of DDIT3 expression in cells treated with BIX. The data are presented as the means ± s.d. of three independent experiments. P values were calculated using Student’s t -test (*** P < 0.001). j The 3D spheroid formation assay. The cells were loaded onto ULA plates after treatment with Fb7-311 and incubated for 48 h. The cells were photographed under a microscope each day. Scale bar, 500 μm. k Western blot analysis of Fb7-311-treated cells using anti-PARP and anti-ACTB antibodies. ACTB was used as the internal control in A498 cell. l RT‒qPCR analysis of EHMT2 and DDIT3 expression in Fb7-311-treated cells. The data are presented as the means ± s.d. of three independent experiments. P values were calculated using Student’s t -tests (** P < 0.01, *** P < 0.001). m , n BIX treatment suppressed the growth of xenograft tumors in nude mice. Both the control and BIX were intraperitoneally injected three times a week after A498 cell implantation: tumor volumes ( P values were calculated using two-way ANOVA (** P < 0.01)) (m) and macroscopic image of tumors on day 24 ( n ). o Representative H&E-stained mouse tumor sections. Scale bars, 200 μm. p Immunohistochemical staining for DDIT3 in mouse tumor sections. Scale bar, 200 μm.
Article Snippet: The human RCC cell lines A498 and Caki-1 were purchased from the Korean Cell Line Bank and cultured in RPMI-1640 supplemented with 10% fetal bovine serum (FBS) and 1% penicillin/streptomycin in a humidified atmosphere with 5% CO 2 at 37 °C.
