Raji Xenograft Model. What is a Xenograft?. Development of an anti-cancer therapeutic requires intense, well planned studies that follow a streamlined path for success. Primary studies are performed in an in vitro setting that allows for high throughput screening and analysis of multiple compounds of interest. This method enables a focused compound screening approach of multiple cell lines within a specific cancer type, or a divergent approach across a broad range of cancer types. Ultimately, in vitro screening results need to be confirmed in an animal model due to in vitro inadequacies of cells cultured on plastic, as this method is far removed from the microenvironment of a tumor.. As the logical next step in therapeutic development is the administration of the test compound in a living animal, a cell line derived xenograft model (CDX) is created by inoculating human cancer cell lines in test animals. The injected cell lines grow into established tumors, thus, permitting efficacy studies of ...
The host microenvironment plays a prominent role in tumor growth, angiogenesis, invasion, metastasis, and response to therapy. Orthotopic tumor model mimics the natural environment of tumor development and provides an effective approach to investigate tumor pathophysiology and develop therapeutic strategies. This protocol describes the technique involving injection of colorectal cancer cell suspension into the intestinal wall of mice to establish an orthotopic colorectal tumor model.
HER2/HER3 dimerization resulting from overexpression of HER2 or neuregulin (NRG1) in cancer leads to HER3-mediated oncogenic activation of PI3K signaling. Although ligand-blocking HER3 antibodies inhibit NRG1-driven tumor growth, they are ineffective against HER2-drive tumor growth because HER2 activates HER3 in a ligand-independent manner. In this study, we describe a novel HER3 monoclonal antibody (LJM716) that can neutralize multiple modes of HER3 activation, making it a superior candidate for clinical translation as a therapeutic candidate. LJM716 was a potent inhibitor of HER3/AKT phosphorylation and proliferation in HER2-amplified and NRG1-expressing cancer cells and it displayed single agent efficacy in tumor xenograft models. Combining LJM716 with agents that target HER2 or EGFR produced synergistic antitumor activity in vitro and in vivo. In particular, combining LJM716 with trastuzumab produced a more potent inhibition of signaling and cell proliferation than trastuzumab/pertuzumab ...
Trop-2 (trophoblastic antigen-2; aka EGP-1, GA733-1) is a surface glycoprotein differentially expressed on a variety of malignant epithelial cancers, making it an interesting target for antibody directed therapeutics. Preclinical studies with an anti-Trop-2 IgG, designated RS7 (Stein et al. Cancer Res 1990;50:1330-36), showed targeting of human cancer xenografts and antibody internalization. An antibody-drug conjugate (IMMU-132) was prepared by conjugating humanized RS7 with SN-38 (6 moles SN-38/IgG), the highly potent topoisomerase-I-inhibitor metabolite of irinotecan. The linker allows SN-38 release from the conjugate at low pH, such as in the tumor microenvironment or lysosomes. IMMU-132 was effective against several human cancer xenograft models, with a high therapeutic window. Primate studies found dose-limiting neutropenia and gastrointestinal (GI) toxicity identical to irinotecan, but no selective damage to normal tissues expressing Trop-2 (Cardillo et al. Clin Cancer Res ...

Metastatic uveal melanoma is a highly fatal disease; most patients die from their hepatic metastasis within 1 year. A major drawback in the development of new treatments for metastatic uveal melanoma is the difficulty in obtaining appropriate cell lines and the lack of appropriate animal models. Patient-derived xenograft (PDX) tumor models, bearing ectopically implanted tumors at a subcutaneous site, have been developed. However, these ectopically implanted PDX models have obstacles to translational research, including a low engraftment rate, slow tumor growth, and biological changes after multiple passages due to the different microenvironment. To overcome these limitations, we developed a new method to directly transplant biopsy specimens to the liver of immunocompromised mice. By using two metastatic uveal melanoma cell lines, we demonstrated that the liver provides a more suitable microenvironment for tumor growth compared to subcutaneous sites and that surgical orthotopic implantation (SOI) of
Recent experimental and clinical data demonstrate that regulatory T cells (Tregs) are recruited to the tumor site where they can suppress tumor-specific immunity. Increasing evidence indicates that Treg recruitment to the tumor is mediated by the production of chemokine CCL22, a ligand of chemokine receptor CCR4, by tumor cells and tumor resident macrophages. Therefore, blocking Treg migration and function through CCL22/CCR4 axis may have therapeutic value in cancer treatment. With a mouse model bearing CCL22-secreting ovarian xenograft and tumor-specific T cells, we assessed the therapeutic effect of human anti-CCR4 antibody mAb2-3 to block or modulate immunological axes involved in tumor immune evasion. CCR4 expression was demonstrated at a high level on functional CD4+CD25+ Tregs and T cell proliferation was restored by removal of CCR4+ Tregs in vitro. In vivo examinations showed isotyping of mAb2-3 had marked effects on its mode of action: mAb2-3 IgG1 results in Treg depletion whereas IgG4 ...
We found that vandetanib augmented the antitumor activity of cisplatin with concurrent radiation in preclinical models of human cisplatin and radiation-resistant HNSCC in vitro and in vivo. Vandetanib plus cisplatin effectively radiosensitized HNSCC cells both in vitro and in vivo. Vandetanib alone or in combination with cisplatin and/or radiation inhibited the phosphorylation of EGFR and its downstream mediators, Akt and MAPK, both in vitro and in vivo. Treatment with vandetanib, cisplatin, and radiation led to reductions in tumor size and cervical lymph node metastases and prolonged survival in an orthotopic nude mouse model by inducing apoptosis in tumor and endothelial cells.. Chemoradiotherapy with cisplatin remains a standard treatment for patients with HNSCC, with the aim of improving organ preservation as well as patient survival (31). However, resistance to cisplatin or radiation leading to treatment failure and locoregional recurrence is a critical problem. In addition, cisplatin ...
Scientists at Sanford Burnham Prebys Medical Discovery Institute have identified a combination of two anti-cancer compounds that shrank pancreatic tumors in mice-supporting the immediate evaluation of the drugs in a clinical trial. U.S. Food and Drug Administration (FDA)-approved versions of the compounds are used today to treat certain leukemias and solid tumors, including melanoma. The study was published in Nature Cell Biology. "The sad reality is that at present, pancreatic cancer therapy is lagging since there is no effective treatment for these tumors," says Zeev Ronai, Ph.D., a professor in Sanford Burnham Prebys Tumor Initiation and Maintenance Program and senior author of the study." Our study identifies a potential treatment combination that can immediately be tested against these aggressive tumors. We are already meeting with oncologists at Oregon Health & Science University to discuss how to advance this discovery into clinical evaluation." Pancreatic cancer is one of the deadliest ...

The cytokine TWEAK and its receptor, Fn14, have emerged as potentially valuable targets for cancer therapy. Granzyme B (GrB)-containing Fn14-targeted constructs were generated containing either the Fn14 ligand TWEAK (GrB-TWEAK) or an anti-Fn14 humanized single-chain antibody (GrB-Fc-IT4) as the targeting moieties. Both constructs showed high affinity and selective cytotoxicity against a panel of Fn14-expressing human tumor cells including triple-negative breast cancer (TNBC) lines. Cellular expression of the GrB inhibitor PI-9 in target cells had no impact on the cytotoxic effect of either construct. Cellular expression of MDR1 showed no cross-resistance to the fusion constructs. GrB-TWEAK and GrB-Fc-IT4 activated intracellular caspase cascades and cytochrome c-related proapoptotic pathways consistent with the known intracellular functions of GrB in target cells. Treatment of mice bearing established HT-29 xenografts with GrB-TWEAK showed significant tumor growth inhibition compared with vehicle ...
This study shows that in vivo serial 89Zr-bevacizumab PET imaging can visualize reduced tumor VEGF-A levels upon treatment with everolimus in an ovarian cancer xenograft model.. The relatively modest activity of temsirolimus observed in patients with ovarian cancer underscores the need for patient selection. Responses limited to a subset of patients with ovarian cancer have also been observed with VEGF(R)-targeted antiangiogenic drugs, as well as several other targeted agents, and could result from marked molecular heterogeneity, which is characteristic to ovarian cancer (27, 28). The discovery of biomarkers for (early) response prediction might permit the selection of patients that are likely to benefit from single-agent mTOR inhibition or mTOR inhibitor-based combination regimens. Several proteins involved in mTOR signaling have been proposed as suitable biomarkers for response. Phosphorylation of mTOR in ovarian cancer specimens is a poor indicator of its kinase activity (5). Phosphorylation ...

The efficacy of [Pt(O,O-acac)(γ-acac)(DMS) ] was assessed using a xenograft model of breast cancer developed by injection of MCF-7 cells in the flank of BALB/c nude mice. Treatment of solid tumor-bearing mice with [Pt(O,O-acac)(γ-acac)(DMS)] induced up to 50% reduction of tumor mass compared with an average 10% inhibition recorded in cisplatin-treated animals. Thus, chemotherapy with [Pt(O,O-acac)(γ-acac) (DMS)] was much more effective than ...
Current treatments for patients with a PDAC are not highly effective primarily due to the recently discovered fact that these tumors are both molecularly and clinically heterogeneous. For example, the response of these tumors to gemcitabine and Folfirinox, the two gold standard therapies against PDAC, is only 10% (Burris et al, 1997) and 31% (Conroy et al, 2011), respectively. The variability in this response seems to be due, on one hand, to the difficulty for the drugs to reach the transformed cells because of the compact PDAC stroma (resulting in hypovascularization) and, on the other hand, to the marked differences in cellular susceptibility to drugs into the tumors due to their molecular heterogeneity. Therefore, it has become important to develop methods to stratify patients in a manner that allows predicting their susceptibility to the treatments so as to increase their therapeutic responses which will result in increased survival expectancies. Consequently, in this work, we focused our ...
In the B901L xenograft model, tumor regrowth was observed following initial strong tumor regression by erlotinib monotherapy (Fig. 1). In the erlotinib-sensitive phase, pEGFR and its downstream pERK, pAKT, and pSTAT3 were suppressed by erlotinib (Fig. 2A), and the expression of tumor VEGF was decreased significantly compared with control (Fig. 3B) in agreement with previously reported downregulation of VEGF by EGFR-TKIs (16,17,21). On the other hand, pERK, pAKT, and pSTAT3 were increased in the erlotinib-refractory phase compared with that in the erlotinib-sensitive phase, although pEGFR was still suppressed (Fig. 3A). The T790M mutation, which is one of the major erlotinib resistance mechanisms occurring in the EGFR tyrosine kinase domain and causing a relative decrease in binding with EGFR-TKIs, was not detected after progression in this model (Fig. 4). Accordingly, it is suggested that bypass pathways other than EGFR activate signaling pathways leading to tumor regrowth. To date, MET ...

Immunohistochemistry was used to quantitate vessel counts ...
Great progress has been made over the past two decades in the development of animal models for ovarian cancer. Each generation of animal model has had its advantages and limitations. The earliest models used a xenograft approach in which human ovarian tumor cells or tissues were grown in immunodeficient mice (17, 27, 32, 33, 36). The xenograft model preserved the complex interactions that occur between cancer cells and their microenvironment, including stromal-epithelial cell interactions, as well as influences of matrix proteins, growth factors, and angiogenesis. Thus, this model was a great advance over cell culture model systems and advanced the study of therapeutic interventions. However, an important weakness in the xenograft model was the lack of host immunity, which severely limited the ability to reliably predict the effect of noncancer immune-host influences on outcomes. In addition, tumors were introduced in the xenograft model rather than arising as primary lesions in the ovary, thus ...

A protein that plays an important role in pancreatic cancer growth has been identified by the researchers at Stanford University School of Medicine.
Downregulation of microRNA-200b (miR-200b) has been identified in a range of cancers, yet the specific mechanisms whereby it influences lung cancer growth require further exploration. We determined that lung cancer patient tumor samples exhibit decreased miR-200b expression, and we further found this miRNA to inhibit tumor growth via interfering with ERK1/2 and AKT signaling, targeting p70S6K1 to suppress HIF-1α expression. This miRNA further rendered H1299 cells more sensitive to cisplatin while impairing their proliferative and invasive potential through its ability to target and inhibit the activity of p70S6K1. These results were further confirmed in a murine xenograft model in which miR-200b also inhibited the growth of tumor and suppressed p70S6K1, p-AKT, p-ERK1/2, and HIF-1α expression. These findings clearly demonstrate a role for miR-200b in suppressing lung cancer development, making it a potentially relevant target for future diagnostic and therapeutic interventions.
