Microscope image (406) magnification of U937 cells after exposure to SM-TNs. a) Untreated U937 cells. b) U937 cells treated with 200 nM, and 35 nM ODS empty shells. c) U937 cells treated with microcrystalline (free) Taxol prepared by sonicating Taxol in 20%H3PO4/0.8% SDS solution. d) U937 cells treated with 200 nM SM-TN. A SM-TN is seen in the middle of the picture. e) U937 cells treated with 35 nM SMTN.The nanowires are too small to see at this magnification, but their effect on the cells is clearly visible. Scale bar = 10 mm.

for HXO-RB44 cells, IC50 values for VCR were changed in the different SG600 treatment groups. The results are representative of three independent  experiments and of f our replicates in each experiment.

Matrigel invasion assay of H1299 cells treated with SDF-1α or SDF-1α plus Epothilone B prior to 0 or 2 Gy irradiation. After the treatment for 12 h, the H1299 cells that migrated to the bottom surface of the membrane were stained with Giemsa, and the number of migrated cells was calculated manually.

Cell viability in H292 monolayer cells after 3-day treatment and spheroid volume in H292 3D culture after 7-day treatment with ABT751. Data points are means ?SD for three individual experiments. IC50 values were calculated to emphasize the differences in drug potency in 2D verses 3D cultures. ABT751, IC50 of 177.2 ?17.3 nM for 2D and 670.2 ?257.6 nM for 3D.

A, HeLa cells were treated with DMSO, Taxol (100 nM for 16 h), or Nocodazole (Noco, 100 ng/ml for 16 h). Total cell lysates were probed with the indicated antibodies against Hippo components on Phos-tag SDS-polyacrylamide gels. O and * mark the non-phosphorylated and phosphorylated proteins, respectively.

ABCB1 functional inhibition using elacridar re-sensitizes TaxR and DU145-DTXR cells to cabazitaxel treatment. A. TaxR and DU145-DTXR cells were subjected to cell growth assays using either vehicle (DMSO), elacridar (0.5μM), cabazitaxel (1nM), or a combination of elacridar and cabazitaxel. Cells were counted 72 hours post-treatment. B. TaxR and DU145-DTXR cells were treated with either vehicle (DMSO), elacridar (0.5μM), cabazitaxel (1nM), or a combination of both elacridar and cabazitaxel for 72 hours. Whole cell lysates were then prepared and subjected to western blot analysis using indicated antibodies. Tubulin served as a loading control. c-PARP = cleaved-PARP, C = control (DMSO) treatment, Elac = elacridar, CTX = cabazitaxel. All data is presented as percent of control mean ± standard deviation. * = p-value ≤ 0.05.

CYT997 inhibits cellular proliferation in acute myeloid leukemia (AML) cell lines. Cell viability was measured by a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay in 96-well plates in the presence of increasing concentrations of CYT997 for 24 h.The results represent the mean ?SD of four replicates.

Real-time hemodynamic changes in the tumor upon administration of CA4P. Panel A shows the MRI anatomical reference of the tumor, followed by sO2 maps of a slice of brain showing the largest cross section of the tumor at time points 0, 1, 4 and 6 h. post CA4P administration. Panel B shows the real-time sO2 changes in the tumor and contralateral brain occurring immediately post CA4P administration over 1 hour in a representative animal. SD is represented by lighter shades on the graph. Panel C shows the real-time sO2 changes in the tumor and contralateral brain occurring immediately post CA4P administration (n = 4). Panel D shows the quantification of hypoxia in tumors using CAIX as a marker at times 0 (n = 3), 1 (n = 4) and 6 h. (n = 3) post CA4P administration. Unpaired t-test showed statistically significant difference in CAIX staining at 1 hour post CA4P administration compared to 0 and 6 hours. ** ‐ P > 0.01. Black dotted circle and Red full circle denote the ROIs drawn at the tumor and contralateral brain respectively to compute the sO2.

Dose-dependent disruption in the distribution of α-tubulin following exposure to albendazole. Experimental treatments included vehicle (DMSO), 0.1 μM, 0.5 μM and 1 μM albendazole for 24 hours. α-tubulin was visualized using immunofluorescence (green) and nuclei were stained with DAPI (blue). 40x fluorescence microscopy was used to assess changes in cellular morphology and tubulin distribution.

Spindle morphology before and after addition of the HSET inhibitor (CW069, 200 μM). MTs were visualized by SiR-tubulin staining. Arrowheads indicate split poles. Images were acquired with 5 z-sections (separated by 3 μm) and displayed after maxium projection. Two independent KO lines were analysed (clones #4 and #23). Bar, 5 μm.

(B) Viability of cells after exposure to 0, 10, or 10,000 nM docetaxel, assessed by calcein-AM staining (green, left panels) and ethidium homodimer-1 (red, middle panels). Right panels show merged images. Scale bars = 100 μm.

Activity of vinorelbine in NSCLC cell lines in cell viability assay. Activity of vinorelbine NCI-H23, NCI-H460, and NCC44 cell lines in a Cell Titer Glo cell viability assay. Cells were treated with increasing drug concentrations from 0-10000 nM. The data are plotted as the mean % of control cells against the corresponding drug concentration.
