9-ING-41, a small molecule inhibitor of GSK-3β, potentiates the effects of chemotherapy in KRAS mutated colorectal cancer

ABSTRACT: Despite the prevalence of KRAS mutations in colorectal cancer, there is no K-Ras targeted therapies for these tumors and available treatment options are limited for metastatic disease. GSK-3β has been demonstrated to be a critically important kinase for survival and proliferation of K-Ras-depended pancreatic cancer cells. In this study we tested 9-ING-41, a small molecule inhibitor of GSK-3β, in patient-derived tumor organoid models of colorectal cancer. We demonstrated that addition of 9-ING-41 to the standard of care drugs 5-FU and oxaliplatin could significantly enhance inhibition of the growth of colorectal cancer cells harboring KRAS mutations. The results of the transcriptomic analysis support our findings of cell cycle arrest and DNA repair deficiency in 9-ING-41-treated colorectal cancer cells. Moreover, we found substantial similarity in the changes of transcriptomic profile after inhibition of GSK-3β and suppression of STK33, another critically important kinase for K-Ras-dependent cells. Overall, the results of this study provide a rationale for the inclusion of patients with mutant KRAS colorectal cancer in clinical studies of 9-ING-41 and other GSK-3 inhibitors.

Impact of elraglusib (9-ING-41) treatment on gene expression in human colorectal cancer and immune cell lines.

Project description:A growing body of literature evaluates the potential anti-cancer and immunostimulatory effects of GSK-3 inhibition. Accordingly, we sought to evaluate GSK-3 inhibitor elraglusib (9-ING-41) and its impact on gene expression in both human colorectal cancer (CRC) cell lines and human immune cell lines. We used microarrays to detail the differential gene expression that occurs post-treatment with GSK-3 inhibitor 9-ING-41 (elraglusib).

GSK-3alpha Promotes Oncogenic KRAS Function in Pancreatic Cancer via TAK1-TAB Stabilization and Regulation of Non-Canonical NF-kB

Project description:Mutations in KRAS occur in a variety of tumors of epithelial origin, driving the oncogenic phenotype.The NF-kB transcription factor pathway is important for oncogenic RAS to transform cells and to drive tumorigenesis in animal models. Recently TAK1, an upstream regulator of IKK which controls canonical NF-kB, was shown to be important for chemoresistance in pancreatic cancer and for regulating KRAS+ colorectal cancer cell growth and survival. Here we show that GSK-3alpha is upregulated by KRAS leading to interaction with TAK1 to stabilize the TAK1/TAB complex to promote IKK activity. Additionally, GSK-3alpha is required for promoting critical non-canonical NF-kB signaling in pancreatic cancer cells. Pharmacologic inhibition of GSK-3 suppresses growth of human pancreatic tumor explants, consistent with loss of expression of genes such as c-myc and TERT. These data identify GSK-3alpha as a key downstream effector of oncogenic RAS via its ability to coordinately regulate distinct NF-kB signaling pathways GSK-3 inhibition at 2 and 8 hours

GSK-3β inhibition promotes engraftment of ex vivo expanded hematopoietic stem cells

Project description:Glycogen synthase kinase-3β (GSK-3β) has been recently identified as an important regulator of stem cell function. In vitro studies show that GSK-3β inhibition delays proliferation of human haematopoietic progenitor cells while increasing numbers of late dividing multipotent progenitors. Gene expression analysis revealed that GSK-3β inhibition modulates the expression of a subset of genes that are transcriptional targets for cytokines. GSK-3β inhibition antagonised down-regulation of genes encoding cyclin dependent kinase inhibitor p57 and a member of the growth arrest and DNA damage 45 family, GADD45B as well as up-regulation of cyclin D1 by cytokines, providing a possible mechanism for the BIO-induced delay in cell cycle progression. Surprisingly, inhibition of GSK-3β earlier shown to prevent β-catenin degradation and promote the nuclear accumulation of β-catenin was not sufficient to activate its transcriptional targets in haematopoietic stem cells. GSK-3β inhibition up-regulated the expression of a several positive regulators of stem cell function suppressed during cytokine-induced proliferation. The data supports a clinical role for GSK-3β inhibition to improve engraftment efficiency of ex vivo expanded stem cells.

Linking FOXO3, NCOA3, and TCF7L2 to Ras pathway phenotypes through a genome-wide forward genetic screen in human colorectal cancer cellsLinking FOXO3, NCOA3, and TCF7L2 to Ras pathway phenotypes through a genome-wide forward genetic screen in human colorectal cancer cells

Project description:Background: The Ras pathway genes KRAS, BRAF or ERBBs have somatic mutations in ~60% of human colorectal carcinomas. At present, it is unknown whether the remaining cases lack mutations activating the Ras pathway, or whether they have acquired mutations in genes hitherto not known to belong to the pathway. Methods: To address the second possibility, and extend the compendium of Ras pathway genes, we used genome-wide transposon mutagenesis of two human colorectal cancer cell systems deprived of their activating KRAS or BRAF allele to identify genes enabling growth in low glucose, a Ras pathway phenotype, when targeted. Results: Of the 163 recurrently targeted genes in the two different genetic backgrounds, one third were known cancer genes and one-fifth had links to the EGFR/Ras/MAPK pathway. When compared to cancer genome sequencing datasets, 9 genes also mutated in human colorectal cancers were identified. Among these, stable knock-down of FOXO3, NCOA3, and TCF7L2 restored growth in low glucose but reduced MEK/MAPK phosphorylation, reduced anchorage-independent growth, and modulated expressions of GLUT1 and Ras pathway related proteins. Knock-down of NCOA3 and FOXO3 significantly decreased the sensitivity to cetuximab of KRAS mutant but not wild-type cells. Conclusions: This work establishes a proof-of-concept that human cell based genome-wide forward genetic screens can assign genes to pathways with clinical importance in human colorectal cancer.

Gene expression profiling by DNA microarray in Colo741 cell line transfected by KRas-G12D or KRas-G12V

Project description:Mutations of the proto-oncogene KRas, together with the inactivation of the onco-suppressor genes APC and TP53, are considered to have an important role both in the carcinogenesis and in the colorectal tumor progression. The oncogene K-ras has activating mutations, especially in codon 12, in about 40% to 50% of colorectal carcinomas (Andreyev et al., 1998). The mechanism by which oncogenic K-ras alone contribuites to tumor progression in colon cancer is largely unknown. To this end, we have developed a model system where the colorectal adenocarcinoma cell line Colo741 has been stably trasfected with the Kras-G12V or Kras-G12D mutated oncogenes. Our results demonstrate how expression profiling data can be used to interpret changes in cellular characteristics induced by transfection and hence provide some clues as to the mechanisms by which different activated K-Ras impair processes mediated by endogenous wild-type KRas proteins.

MicroRNA expression profiling identified miR-31-5p/3p as associated with time to progression in wild-type KRAS metastatic colorectal cancer treated with cetuximab but not panitumumab

Project description:The aim of our study was to investigate whether miRNAs could serve as predictive biomarkers to anti-EGFR therapy (cetuximab, panitumumab) in patients with KRAS wild-type (wt-KRAS) metastatic colorectal cancer (mCRC). In our study, historical cohort of 96 patiens with wt-KRAS mCRC (2006-2009) was included and further divided into exploratory and validation cohorts. Large-scale miRNAs expression profiling was performed on the exploratory cohort of 41 wt-KRAS mCRC patients treated with cetuximab to identify miRNAs associated with time to progression (TTP). The validation was performed on two independent cohorts: 30 patients of wt-KRAS mCRC treated with cetuximab and 25 patients of wt-KRAS mCRC treated with panitumumab.
