A ubiquitous feature of cancer cells is their increased mobilization of stress response pathways, as many of these pathways may have to be mobilized by the cancer cells to counterbalance the oncogenic activity and support the tumorigenic state. This overall scenario suggests that a “counter-intuitive” deliberate activation of mitogenic signaling may not only disrupt the homeostasis of cancer cells, but also sensitize them to drugs targeting the stress-coping pathways that are frequently activated in these cells.
While the arsenal of compounds developed to restrain mitogenic signaling in cancer cells is vast, hyperactivation of these pathways for therapeutic purposes is generally uncharted territory.

Cell lines were cultured in RPMI medium, supplemented with 10% FBS, 1% penicillin/streptomycin and 2 mM L-glutamine. All cell lines were cultured at 37° C. in 5% CO2. All cell lines were validated by STR profiling. Mycoplasma tests were performed every 2-3 months.
Drug-response assays were performed in triplicate, using black-walled 384-well plates. Cells were plated with a 20% density (approximately) and incubated for approximately 24 hours to allow attachment to the plate. Drugs were then added to the cells using the Tecan D300e digital dispenser. 10 µM phenylarsine oxide was used as positive control (0% cell viability) and DMSO was used as negative control (100% cell viability). 3-5 days later, culture medium was removed and resazurin was added to the plates. After 1-4 hours incubation (depending on the cell line), fluorescence (560Ex/590Em) was recorded using the EnVision (Perkin Elmer).
IncuCyte assays were performed in triplicate, using black-walled 96-well plates. Cells were plated at a very low density. Plates were then placed in the in the IncuCyte ZOOM, which imaged the cells every 4 h. Approximately 24 h after plating drugs were added to the cells using the Tecan D300e digital dispenser, as indicated. Phase-contrast images were collected and analyzed to detect cell proliferation based on confluence.
In some cases, as indicated, IncuCyte® Caspase-3/7 green apoptosis assay reagent (Essen Bioscience 4440) was also added to the culture medium. Here, green fluorescent images were also collected and analyzed (by dividing the detected green fluorescence confluence by the phase-contrast confluence) to detect caspase 3/7 activity.
Cells were plated at a very low density in 6-well plates and incubated for approximately 24 h to allow attachment to the plates. Drugs were then added to the cells using the Tecan D300e digital dispenser, as indicated. The culture media/drugs were refreshed every 2-3 days. When control wells (DMSO) were confluent cells were fixed using a solution of 2% formaldehyde (Millipore 104002) diluted in phosphate-buffered saline (PBS). Two hours later, they were stained, using a solution of 0.1% crystal violet (Sigma HT90132) diluted in water. No more than 10 min later the staining solution was removed, plates were washed with water and left to dry overnight. Finally, plates were scanned and stored.
After the indicated culture period and drug treatment, cells were washed with cold PBS, then lysed with RIPA buffer (25 mM Tris-HCl, pH 7.6, 150 mM NaCl, 1% NP-40, 1% sodium deoxycholate, 0.1% SDS) containing Complete Protease Inhibitor cocktail and phosphatase inhibitor cocktails II and III. Samples were then centrifuged for 10 min at 15,000 x g at 4° C. and supernatant was collected. Protein concentration of the samples was normalized after performing a Bicinchoninic Acid (BCA) assay. Protein samples (denatured with DTT followed by 5 min heating at 95° C.) were then loaded in a 4-12% polyacrylamide gel. Gels were run (SDS-PAGE) for approximately 45 min at 175 volts. Proteins were transferred from the gel to a polyvinylidene fluoride (PVDF) membrane at 330 mA for 90 min. After the transfer, membranes were incubated in blocking solution (5% bovine serum albumin (BSA) in PBS with 0.1% Tween-20 (PBS-T)). Subsequently, membranes were probed with primary antibody in blocking solution (1:1000) overnight at 4° C. Membranes were then washed 3 times for 10 min with PBS-T, followed by 1 h incubation at room temperature with the secondary antibody (HRP conjugated, 1:10,000) in blocking solution. Membranes were again washed 3 times for 10 min in PBS-T. Finally, a chemiluminescence substrate (ECL, Bio-Rad) was added to the membranes and the signal was imaged using the ChemiDoc-Touch (Bio-Rad)
The appropriate number of cells to achieve a 250-fold representation of the Brunello library for all the screen arms and replicates were transduced at approximately 50% confluence in the presence of polybrene (8 µg/mL) with the appropriate volume of the lentiviral-packaged sgRNA library. Cells were incubated overnight, followed by replacement of the lentivirus-containing medium with fresh medium containing puromycin (2 µg/mL). The lentivirus volume to achieve a MOI of 0.3, as well as the puromycin concentration to achieve a complete selection in 3 days was previously determined for each cell line. After puromycin selection, cells were split into the indicated arms/replicates (for each arm, the appropriate number of cells to keep a 250-fold representation of the library was plated at approximately 10-20% confluence) and a T0 (reference) time point was harvested. Cells were maintained as indicated. In case a passage was required, cells were reseeded at the appropriate number to keep at least a 500-fold representation of the library. Cells (enough to keep at least a 500-fold representation of the library, to account for losses during DNA extraction) were collected when indicated, washed with PBS, pelleted and stored at -80° C. until DNA extraction.
Genomic DNA (gDNA) was extracted (Zymo Research, D3024) from cell pellets according to the manufacturer’s instructions. For every sample, gDNA was quantified and the necessary DNA to maintain a 250-fold representation of the library was used for subsequent procedures (for this, an assumption was made that that each cell contains 6.6 pg genomic DNA). Each sample was divided over 50 µl PCR reactions (using a maximum of 1 µg gDNA per reaction) using barcoded forward primers to be able to deconvolute multiplexed samples after next generation sequencing. PCR mixture per reaction: 10 µl 5x HF Buffer, 1 µl 10 µM forward primer, 1 µl 10 µM reverse primer, 0.5 µl Phusion polymerase (Thermo Fisher, F-530XL), 1 µl 10 mM dNTPs, adding H2O and template to 50 µl. Cycling conditions: 30 sec at 98° C., 20× (30 sec at 98° C., 30 sec at 60° C., 1 min at 72° C.), 5 min at 72° C. The products of all reactions from the same sample were pooled and 2 µl of this pool was used in a subsequent PCR reaction using primers containing adapters for next generation sequencing. The same cycling protocol was used, this time for 15 cycles. Next, PCR products were purified using the ISOLATE II PCR and Gel Kit. DNA concentrations were measured, and based on this, samples were equimolarly pooled and subjected to Illumina next generation sequencing (HiSeq 2500 High Output Mode, Single-Read, 65 bp). Mapped read-counts were subsequently used as input for the further analyses.
For each CRISPR screen the sgRNA count data for each sample was normalized for sequence depth using DESeq2, with the difference that the median instead of the total value of a sample was used. The results from the DESeq2 analysis were sorted using the DESeq2 statistic in decreasing order putting the most enriched sgRNA at the top. MAGeCK Robust Rank (RRA) was then used to test for enrichment of the sgRNAs of a gene towards the top for which RRA will generate a multiple testing corrected p-value (FDR).
To evaluate the ability of LB-100 to sensitize cancer cells to stress-targeted drugs, a panel of seven colorectal cancer cell lines having diverse oncogenic driver mutations was chosen (Table 1).
The effect of increasing doses of LB-100 to the Table 1 cell lines, both in short-term cell viability assays (
To identify stress-targeted drugs that can be combined with LB-100 to kill cancer cells, a library of 164 compounds was built targeting the different stress responses associated with a malignant phenotype (i.e., proteotoxic stress, oxidative stress, DNA damage stress, mitotic stress, metabolic stress, and apoptosis evasion). These compounds were investigated in 15 different concentrations using a literature-based concentration range in order to obtain dose-response curves for each of these drugs. A schematic outline of the stress-focused screen is shown in
The stress-focused drug screen also showed that CCT-245737 and SCH-900776 exhibit increased toxicity to HT-29 cells in the presence of a sub-lethal concentration of LB-100, and rabusertib and prexasertib exhibit increased toxicity to SW-480 cells in the presence of a sub-lethal concentration of LB-100.
Based on these results, A-1155463, adavosertib, and prexasertib were selected for follow-up validations. Long-term cell proliferation assays, where cells were grown in the absence or presence of LB-100 and the indicated drugs at multiple concentrations for 10-14 days, then fixed and stained, confirmed the increased toxicity of these drugs when combined with LB-100 in SW-480 cells (
Using GDC-0575 as CHK1 inhibitor and adavosertib as a WEE1 kinase inhibitor, the addition of LB-100 increased the cytotoxicity of both drugs in a panel of CRC cells (
In an unbiased investigation of potential vulnerabilities of cells treated with LB-100, a genome-wide CRISPR screen (
Adavosertib was used as the WEE1 kinase inhibitor to investigate the effect of the combination with LB-100 in the panel of CRC cells. Dose-response curves for this drug indicated IC50s ranging from about 0.18 to 1 µM across the panel (
The combination of multiple concentrations of LB-100 and adavosertib was evaluated to determine if a synergistic effect is observed in a panel of colorectal cancer cell lines. In the synergy studies, cells were cultured with the indicated concentrations of LB-100 and adavosertib for 5 days, then the cell viability was measured using resazurin. The relative inhibition of cell viability is shown for each pair of concentrations. Synergy scores (ZIP) were calculated using the SynergyFinder 2.0 online tool. A score above 10 indicates synergy. Average synergy across the panel is highlighted at the bottom right box. The matrices in
A similar synergy experiment was carried out by combining LB-100 with prexasertib. Across each of the matrices, the results consistently showed that LB-100 also synergizes with prexasertib in the seven colorectal cancer cell lines, with an average synergy score of 19.2 (
To evaluate whether LB-100 promotes similar sensitization to stress-targeted drugs in a different cancer cell line, a similar stress-focused drug screen was performed in RBE cholangiocarcinoma cells. As shown in
RBE cells were plated and incubated overnight to allow attachment to the plate. Cells were then treated at the indicated conditions and toxicity was measured by IncuCyte® as shown by the proliferation curves provided in
The same drug combinations were also investigated in five additional cholangiocarcinoma cell lines under the conditions outlined above. From these studies it was found that the combinations exhibited increased toxicity compared to the single-drug treatment in all the cell lines, despite differences in sensitivity across the cell lines (
The efficacy of the LB-100/adavosertib combination in the CRC cell lines encouraged further evaluation in other tumor types lacking effective treatment options. Pancreatic ductal adenocarcinomas (PDACs) are refractory to conventional therapies and the 5-year survival rates remain one of the lowest among all cancers. Similarly, despite a much lower overall incidence, cholangiocarcinomas (CCAs) share with PDACs the frequent lack of response to conventional therapies and the dismal prognosis. A panel of four PDAC cell lines and a similar one with CCA cells were assembled to assess the efficacy of LB-100 and adavosertib in these cancer types. LB-100 dose-response curves revealed IC50s varying from 3.2 to >10 µM in the PDAC cells (
The combination of LB-100 and adavosertib was compared LB-100 and adavosertib each in combination with doxorubicin or gemcitabine. Synergy matrices were prepared using 10 concentrations of each of LB-100 and adavosertib in two cell lines per tumor type. The results showed higher synergy scores for the LB-100 + adavosertib combination compared to combinations with the chemotherapeutic agents in each of the cell lines (
These data reveal remarkable context independence of the synthetic lethality of LB-100 in combination with adavosertib in cancer cell lines from different tissues and diverse genetic backgrounds. This combination is believed to provide therapeutic benefits superior to combinations that are currently under clinical investigation. A mechanistic understanding of this toxicity and the evaluation of the viability of this combination in vivo were investigated.
The ability of LB-100 to synergize with prexasertib in pancreatic cancer cell lines was also investigated. In this study, AspC-1, MIA PaCa-2, and YAPC cells were cultured with the indicated concentrations of LB-100 and prexasertib for 5 days, then the cell viability was measured using resazurin. The relative inhibition of cell viability is shown for each pair of concentrations. Synergy scores (ZIP) were calculated using the SynergyFinder 2.0 online tool. A score above 10 indicates synergy. The synergy matrices shown in
The anti-proliferative effect of LB-100 in combination with adavosertib or prexasertib was also evaluated in OVCAR3 (
Even highly synergistic drug combinations ultimately result in resistance in patients with advanced disease. Since deliberate activation of oncogenic signaling is fundamentally different from inhibition of these signals, a study was conducted to see how cancer cells can acquire resistance to the combination of LB-100 and adavosertib. HT-29 and SW-480 resistant cells (HT-29 CR and SW-480 CR) were selected by culturing them in the presence of the drug combination for over four months. Long-term viability assays showed that despite growing in the presence of the drugs for several months, the combination of LB-100 and adavosertib still partially hindered cell viability in both cell lines. Yet, the reduced toxicity of the single drugs and the combination compared to the respective parental cells is clear (
It was reasoned that acquired resistance to hyper-activation of oncogenic pathways might develop in the opposite direction as is seen when activated pathways are inhibited and thus may lead to the down-modulation of oncogenic signaling. It was found that p-ERK levels remain higher in the combo-resistant cells compared to parental controls. Conversely, c-Jun is no longer hyperactivated in the resistant cells in the presence of drug, suggesting downmodulation of this MAPK signaling arm. Moreover, the levels of active (non-phospho) or total β-catenin are not altered in HT-29 and or SW-480 CR cells compared to the parental cell lines. However, the levels of the β-catenin targets AXIN2 and MYC, as well as the modulator of β-catenin transcriptional activity BCL9L were lower in CR cells irrespective of the presence of the drugs (
The data above showing reduced oncogenic signaling output after acquired resistance show an unexpected outcome for the combination of LB-100 and adavosertib: loss of the oncogenic phenotype as a result of drug resistance. Anchorage-independent proliferation is a common trait of transformed cells and can be used as a proxy for oncogenic potential. How acquired resistance to this combination would modulate anchorage-independent proliferation in these CRC cell lines was considered. Parental SW-480 cells showed similar endpoint viability both in attached or anchorage-independent conditions. The addition of this drug combination also similarly restrained cell viability under both conditions (
SW-480 parental and CR cells were transplanted into immunocompromised mice, and tumor growth was monitored for 2 months. The results showed clear engraftment within the first 25 days and steady tumor growth in mice transplanted with SW-480 parental cells. Conversely, SW-480 CR cells either failed to develop tumors or developed tumors only over 50 days after transplantation (
Altogether, the data from the stress-focused drug screens, the genome-wide CRISPR screen, and the validations across colorectal, cholangiocarcinoma, high-grade ovarian cancer and pancreatic ductal adenocarcinoma cell lines indicate that combining (a) LB-100 and (b) a WEE1 or CHK1 inhibitor kills cancer cells from different tissues and genetic backgrounds.
