Thap-OH demonstrates <t>anti-NOTCH1</t> and antileukemia properties in T-ALL in vitro. (A) Effect of Thap-OH on SERCA binding. Lysates from T-ALL cells (ALL/SIL) were cotreated with the indicated concentrations of biotinylated thapsigargin or Thap-OH for 6 h and subjected to streptavidin pull-down for 24 h. The immunoblot was stained with SERCA2 and SERCA3 antibodies. (B) Effect of 24 h of Thap-OH treatment on NOTCH1 cell-surface staining as assessed by flow cytometry. (C) Effect of Thap-OH treatment for 24 h on NOTCH1 (N1) processing and activation in T-ALL cell lines all with heterodimerization mutations (DND41 and ALL/SIL (L1594PΔPEST), PF382 (L1575PΔPEST), and RPMI 8402 (ins1584PVELMPPE). The blot was stained with an antibody against the C terminus of NOTCH1 that recognizes both the furin-processed NOTCH1 transmembrane subunit (TM) and the unprocessed NOTCH1 precursor (FL). The immunoblot was also stained with anti-ICN1 antibody (Val1744) and GAPDH as a loading control. (D) Effect of Thap-OH treatment on cell viability after 72 h of treatment in NOTCH1 mutated T-ALL cells (ALL/SIL, DND41, PF382, RPMI 8402) or wild type (LOUCY, MOLT16, SUPT11). Statistical significance for mutated versus wild type (*, P ≤ 0.05; **, P ≤ 0.01) was determined by one-way ANOVA with Bonferroni’s correction for multiple comparison testing. Error bars denote the mean ± SD of four NOTCH1 mutated T-ALL cell lines (ALL/SIL, DND41, PF382, and RPMI 8402) and three NOTCH1 wild-type T-ALL cell lines (LOUCY, MOLT16, and SUPT11). (E) Effect of Thap-OH treatment (24 h) on processing of NOTCH1 mutant (ALL/SIL) or wild-type (LOUCY, MOLT16) NOTCH1 receptors. NOTCH1 (N1) was detected with an antibody against the C terminus of NOTCH1 that recognizes the furin-processed NOTCH1 transmembrane subunit (TM) and the unprocessed NOTCH1 precursor (FL). GAPDH was used as loading control. (F) Effect of Thap-OH treatment (6 and 12 h) on wild-type NOTCH1 (Loucy, MOLT16) cell surface staining as assessed by flow cytometry. (G) Effect of Thap-OH treatment (6 and 12 h) on mutated NOTCH1 (PF382, RPMI 8402) cell surface staining as assessed by flow cytometry.

(A) mRNA expression detected by real-time RT-PCR showing elevated Notch1 mRNA expression in localized and metastatic tumors compared to non-tumor(NT) tissues (P = 0.001 and P = 0.000 respectively), and higher expression in metastatic tumors compared to localized tumors (P = 0.028); On the right panel, analysis showing elevated Jagged1 mRNA expression in tumors compared to NT (P = 0.000 and P = 0.000 for localized and metastatic tumors respectively), but lower expression in metastatic tumors compared to localized tumors (P = 0.005). Each dot representing a tissue sample. (B) Protein expression detected by western-blot assay showing elevated expression of Notch1 and Jagged1 protein in tumor tissues compared to non-tumor tissues. The right panel was the densitometric analysis of the bands. The data shown are mean±SD.
