Figure Lengend Snippet: Cisplatin-resistant TGCT cells have a less robust transcriptional response to cisplatin compared to parental cells. ( A ) Volcano plots of the cisplatin response of 2102EP parental and three independently derived cisplatin-resistant cell derivatives. ( B ) Volcano plots of the cisplatin response of NT2/D1 parental and two independently derived cisplatin-resistant cell derivatives. ( C ) Volcano plots of the cisplatin response of 833K parental and two independently derived cisplatin-resistant cell derivatives. ( D ) Number of genes upregulated and downregulated (>1.3 fold change and an FDR < 0.01) after cisplatin treatment in indicated parental and resistant cells.

Figure Lengend Snippet: p53/TFRC1/MYC target genes are associated with disease-free survival in TGCT patients. High expression of a partially overlapping subset of genes associated with p53 activation and TFRC1 and MYC repression were associated with increased disease-free survival in TGCT patients as assessed by Kaplan–Meier log-rank tests. HR, hazard ratio; CI, confidence interval.

Figure Lengend Snippet: A, Experimental setup for assessing whether 5-HT is a conserved signal that activates HSF1 in mammalian cells. B, C, Time and dose-dependent change in Hspb1 and Hspb5 mRNA levels respectively, in control and 5-HT treated primary cortical neuronal cultures (n=4 experiments). D, Representative Western blot showing HSPA1A protein levels following 5-HT stimulation of NT2 cells (5µM was applied for 24 hrs to be able to assess protein accumulation; n=4 experiments). E, Quantitation of HSPA1A protein levels in control and 5-HT treated NT2 cells (n=3 experiments). Tubulin was used as internal control. F, Representative Western blot showing HSF1 protein levels in control and HSF1 siRNA treated NT2 cells to confirm siRNA knockdown of HSF1 (n=2 experiments). G, Temporal dynamics of HSPA1A mRNA levels in control and BIMU8 treated NT2 cells (n=5 experiments).

I, Hspa1 and Hspb1 mRNA levels in untreated and BIMU8 treated (10 µM for 10 minutes) primary cortical neuronal cultures (n=3 experiments). J, Quantitation of fluorescence intensity following immunostaining for HSF1 in the nuclei of untreated NT2 cells, NT2 cells treated with BIMU8 (10 µM for 10 minutes), and NT2 cells treated with BIMU8 and H89. Fluorescence intensity values (arbitrary units) were derived using ImageJ following background subtraction. (n=2 experiments; 25 cells). K, SUPT16H mRNA levels in control-siRNA and SUPT16H- siRNA treated NT2 cells to confirm siRNA knockdown of SUPT16H (n=5 experiments). Data in B, C, E, G-K show Mean ± Standard Error of the Mean. Values were normalized to that in either control untreated cells, or control-siRNA treated cells. *, p <0.05; **, p < 0.01 ***, p <0.001; (paired Students t-test).
