P450 (e.g. CYP17)

a, b, Melanoma-bearing mice were treated with avasimibe (Ava) or DMSO control (5 times) (control, n=9; avasimibe, n=8). c-e, STORM analysis of TCR clustering of tumour-infiltrating CD8+ T cells. c, Representative images. d, Ripley’s K-function analysis of TCR molecules. e, The r value at the maximal L(r)-r value of Ripley’s K-function curves (control, n=100; avasimibe, n=85). f, g, A combined therapy (avasimibe and anti-PD-1) or monotherapies (avasimibe or anti-PD-1) in treating melanoma (n=10). Avasimibe, 5 times; anti-PD-1, 4 times. h, i, Cytokine/granule productions of PD-1hi and PD-1lo tumour-infiltrating CD8+ T cells (control, n=12; avasimibe, n=11).

Resistance to itraconazole in MA cells. The parental SUM149-Luc cell line and MA1 cells were treated in parallel with 1 mM itraconazole for 9 days (which killed most of the cells in the parental cell line) and were allowed to recover and grow in a drug-free medium for 5 days before being stained. Since itraconazole was ineffective in killing MA1 cells, the cells grew into a continuous monolayer rather than colonies.

C. Impact of CYP17A1 inhibitors on genes involved in androgen biosynthesis. H295R cells were treated with control (DMSO) or 1 μM orteronel and galeterone for 72 h and then RNA was isolated and transcribed to cDNA. Results of qRT-PCR validation of HSD3B2, CYP17A1 and AKR1C3 genes relative to the housekeeping gene cyclophilin A. Expression of the genes was analyzed by SYBR Green real-time PCR. Analysis of relative gene expression was determined by the 2−ΔΔCt method. *p < 0.05.

Primary hepatocytes were treated with or without 20μM Wy14643/Pioglitazone/Rosiglitazone for 24h followed by stimulation with or without 1μg/ml recombinant human FGF21 for 15min. FGF21 signaling was analyzed by phosphorylation of ERK1/2 and FRS2 examination.

Western blotting confirmed that both GLUT-1 (A) and p-Akt (B) were expressed in Hep-2 cells in different apigenin and cisplatin concentration.

Baicalein suppresses the viability of DU 145 and PC-3 cells. b DU145 cells and c PC-3 cells were treated with different concentrations of baicalein for 24, 48, and 72 h. Baicalein significantly inhibited the viability of both cell lines in a dose-and time-dependent manner. The results are presented as the means ± SD of three independent experiments and the corresponding standard error. *P<0.05; **P<0.01.

Voriconazole increases the osteogenic activity of human osteoblasts in vitro. Osteoblasts were exposed to voriconazole (VCZ) or fluconazole (FCZ) at 15 or 200 μg/ml in osteoinductive medium (OS+) for up to 7 days. As a positive control, cells were also exposed to sodium fluoride (NaF) at 10 μM in nonosteoinductive medium (OS−). Osteoblastic differentiation was evaluated by measuring alkaline phosphatase (ALP) activity (A) and staining for calcium deposition with alazarin red S stain (B and C); calcium deposition was quantified by measuring the absorbance (A415) of extracted alazarin red S (B) and was assessed by the light microscopic appearance (white arrows) of stained osteoblast cultures (C). Values represent the means ± SD. *, P < 0.05, compared to osteoblasts grown under osteogenic conditions without treatment.

U2OS cells were cultured with FAC for 24 hours, washed, followed by chelation with 2 chelators (DFO, DFX) -/+ lysosomal protease inhibitors (E-64d and PepstatinA) and analyzed as in panel A. DFX: Deferasirox.
