Tumor Metabolism Is Affected by Obesity in Preclinical Models of Triple-Negative Breast Cancer. Cancers (Basel) 2022; 14:cancers14030562. [PMID: 35158830 PMCID: PMC8833372 DOI: 10.3390/cancers14030562] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Revised: 01/12/2022] [Accepted: 01/19/2022] [Indexed: 02/04/2023] Open
Abstract
Simple Summary Obesity promotes both development and progression of breast cancer. As a disease, obesity is followed by hyperglycemia, hyperinsulinemia, and hyperlipidemia. The impact of obesity, accumulation of fat depots, and related markers on the metabolism of tumors still remains poorly understood. The aim of this study is to characterize the putative differences in the metabolism of tumors from obese and lean mice. The findings reported here could help tailor personalized treatments targeting tumor metabolism in obese cancer patients by identifying the metabolic preferences of these tumors. Abstract Obesity is characterized by an excessive fat mass accumulation associated with multiple disorders, including impaired glucose homeostasis, altered adipokine levels, and hyperlipidemia. Despite clear associations between tumor progression and obesity, the effects of these disorders on tumor metabolism remain largely unknown. Thus, we studied the metabolic differences between tumors of obese and lean mice in murine models of triple-negative breast cancer (E0771 and PY8819). For this purpose, a real-time hyperpolarized 1-13C-pyruvate-to-lactate conversion was studied before and after glucose administration in fasting mice. This work was completed by U-13C glucose tracing experiments using nuclear magnetic resonance (NMR) spectroscopy, as well as mass spectrometry (MS). Ex vivo analyses included immunostainings of major lipid, glucose, and monocarboxylic acids transporters. On the one hand, we discovered that tumors of obese mice yield higher lactate/pyruvate ratios after glucose administration. On the other hand, we found that the same tumors produce higher levels of lactate and alanine from glucose than tumors from lean mice, while no differences on the expression of key transporters associated with glycolysis (i.e., GLUT1, MCT1, MCT4) have been observed. In conclusion, our data suggests that breast tumor metabolism is regulated by the host’s physiological status, such as obesity and diabetes.

Preclinical Evaluation of the Association of the Cyclin-Dependent Kinase 4/6 Inhibitor, Ribociclib, and Cetuximab in Squamous Cell Carcinoma of the Head and Neck. Cancers (Basel) 2021; 13:cancers13061251. [PMID: 33809148 PMCID: PMC7998503 DOI: 10.3390/cancers13061251] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 03/04/2021] [Accepted: 03/09/2021] [Indexed: 02/06/2023] Open
Abstract
Simple Summary We previously showed that ribociclib induces cell cycle arrest in some human papillomavirus (HPV)-negative squamous cell carcinomas of the head and neck (SCCHN) models. However, in vivo, ribociclib has only a cytostatic effect, suggesting that its activity needs to be optimized in combination with other treatments. We investigated the activity of ribociclib in combination with cetuximab in several HPV-negative SCCHN patient-derived tumor xenograft (PDTX) models. We found that the combination of cetuximab and ribociclib was not significantly more active than cetuximab monotherapy. In addition, our observations also suggest that the combination of cetuximab with a cyclin-dependent kinase (CDK) 4/6 inhibitor may reduce the activity of the CDK4/6 inhibitor in some cetuximab-resistant models. Our work has significant clinical implications since combinations of anti-epidermal growth factor receptor (EGFR) therapy and CDK4/6 inhibitors are currently being investigated in clinical trials. Abstract Epidermal growth factor receptor (EGFR) overexpression is observed in 90% of human papillomavirus (HPV)-negative squamous cell carcinomas of the head and neck (SCCHN). Cell cycle pathway impairments resulting in cyclin-dependent kinase (CDK) 4 and 6 activation, are frequently observed in SCCHN. We investigated the efficacy of ribociclib, a CDK4/6 inhibitor, in combination with cetuximab, a monoclonal antibody targeting the EGFR, in HPV-negative SCCHN patient-derived tumor xenograft (PDTX) models. The combination of cetuximab and ribociclib was not significantly more active than cetuximab monotherapy in all models investigated. In addition, the combination of cetuximab and ribociclib was less active than ribociclib monotherapy in the cetuximab-resistant PDTX models. In these models, a significant downregulation of the retinoblastoma (Rb) protein was observed in cetuximab-treated mice. We also observed Rb downregulation in the SCCHN cell lines chronically exposed and resistant to cetuximab. In addition, Rb downregulation induced interleukin 6 (Il-6) secretion and the Janus kinase family member/signal transducer and activator of transcription (JAK/STAT) pathway activation that might be implicated in the cetuximab resistance of these cell lines. To conclude, cetuximab is not an appropriate partner for ribociclib in cetuximab-resistant SCCHN models. Our work has significant clinical implications since the combination of anti-EGFR therapy with CDK4/6 inhibitors is currently being investigated in clinical trials.

Abstract
Cell-cycle pathway impairments resulting in CDK4 and 6 activation are frequently observed in human papillomavirus (HPV)-negative squamous cell carcinoma of the head and neck (SCCHN). We investigated the activity of ribociclib, a CDK4/6 inhibitor, in SCCHN models with the aim of identifying predictive biomarkers of response. HPV-negative or HPV-positive SCCHN cell lines (n = 8) and patient-derived tumor xenograft (PDTX) models (n = 6) were used. The models were classified according to their sensitivity to ribociclib to investigate potential predictive biomarkers. Ribociclib had a cytostatic effect in some HPV-negative SCCHN models but had no effect in HPV-positive models. In SCCHN cell lines and PDTXs, the retinoblastoma (Rb) protein expression level correlated with ribociclib activity. Rb knockdown was, however, not sufficient to block G0-G1 arrest induced by ribociclib in Detroit-562 where p107, p130, and Forkhead BOX M1 (FOXM1) were also implicated in ribociclib activity. Cell lines harboring epithelial-to-mesenchymal transition (EMT) features were less sensitive to ribociclib than those with an epithelial phenotype. Rb downregulation induced EMT in our Rb-expressing SCCHN cell lines. However, ribociclib still had significant activity in one PDTX model with high Rb and vimentin expression, suggesting that the presence of vimentin alone is not enough to induce ribociclib resistance. These findings suggest that CDK4/6 inhibitors should be investigated in patients with HPV-negative SCCHN with high Rb expression and an epithelial phenotype. Although these biomarkers are not predictive in all cases, they may enrich the population that could benefit from CDK4/6 inhibitors.

Metabolic Imaging Using Hyperpolarized Pyruvate-Lactate Exchange Assesses Response or Resistance to the EGFR Inhibitor Cetuximab in Patient-Derived HNSCC Xenografts. Clin Cancer Res 2019; 26:1932-1943. [PMID: 31831557 DOI: 10.1158/1078-0432.ccr-19-1369] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2019] [Revised: 09/04/2019] [Accepted: 12/05/2019] [Indexed: 11/16/2022]
Abstract
PURPOSE Optimal head and neck squamous cell carcinoma (HNSCC) patient selection for anti-EGFR-based therapy remains an unmet need since only a minority of patients derive long-term benefit from cetuximab treatment. We assessed the ability of state-of-the-art noninvasive in vivo metabolic imaging to probe metabolic shift in cetuximab-sensitive and -resistant HNSCC patient-derived tumor xenografts (PDTXs). EXPERIMENTAL DESIGN Three models selected based on their known sensitivity to cetuximab in patients (cetuximab-sensitive or acquired-resistant HNC007 PDTXs, cetuximab-naïve UCLHN4 PDTXs, and cetuximab-resistant HNC010 PDTXs) were inoculated in athymic nude mice. RESULTS Cetuximab induced tumor size stabilization in mice for 4 weeks in cetuximab-sensitive and -naïve models treated with weekly injections (30 mg/kg) of cetuximab. Hyperpolarized 13C-pyruvate-13C-lactate exchange was significantly decreased in vivo in cetuximab-sensitive xenograft models 8 days after treatment initiation, whereas it was not modified in cetuximab-resistant xenografts. Ex vivo analysis of sensitive tumors resected at day 8 after treatment highlighted specific metabolic changes, likely to participate in the decrease in the lactate to pyruvate ratio in vivo. Diffusion MRI showed a decrease in tumor cellularity in the HNC007-sensitive tumors, but failed to show sensitivity to cetuximab in the UCLHN4 model. CONCLUSIONS This study constitutes the first in vivo demonstration of cetuximab-induced metabolic changes in cetuximab-sensitive HNSCC PDTXs that were not present in resistant tumors. Using metabolic imaging, we were able to identify hyperpolarized 13C-pyruvate as a potential marker for response and resistance to the EGFR inhibitor in HNSCC.

Abstract
Preclinical imaging with radiolabeled probes can provide noninvasive tools to test the efficacy of targeted agents in tumors harboring specific genetic alterations and to identify imaging parameters that can be used as pharmacodynamics markers in cancer patients. The present review will primarily focus on preclinical imaging studies that can accelerate the clinical approval of targeted agents and promote the development of imaging biomarkers for clinical applications. Since only subgroups of patients may benefit from treatment with targeted anticancer agents, the identification of a patient population expressing the target is of primary importance for the success of clinical trials. Preclinical imaging studies tested the ability of new radiolabeled compounds to recognize mutant, amplified, or overexpressed targets and some of these tracers were transferred to the clinical setting. More common tracers such as 18F-Fluorothymidine and 18F-Fluorodeoxyglucose were employed in animal models to test the inhibition of the target and downstream pathways through the evaluation of early changes of proliferation and glucose metabolism allowing the identification of sensitive and resistant tumors. Furthermore, since the majority of patients treated with targeted anticancer agents will invariably develop resistance, preclinical imaging studies were performed to test the efficacy of reversal agents to overcome resistance. These studies provided consistent evidence that imaging with radiolabeled probes can monitor the reversal of drug resistance by newly designed alternative compounds. Finally, despite many difficulties and challenges, preclinical imaging studies targeting the expression of immune checkpoints proved the principle that it is feasible to select patients for immunotherapy based on imaging findings. In conclusion, preclinical imaging can be considered as an integral part of the complex translational process that moves a newly developed targeted agent from laboratory to clinical application intervening in all clinically relevant steps including patient selection, early monitoring of drug effects and reversal of drug resistance.
