Khorana AA, Ahrendt SA, Ryan CK, Francis CW, Hruban RH, Hu YC, et al. (DOCX 489 kb), Table S1. 2014;34(9):1977–84. The addition of NET supernatant to RAGE knockout blood did not result in increased platelet aggregation. Autophagy mediates the delivery of thrombogenic tissue factor to neutrophil extracellular traps in human sepsis. For general information, Learn About Clinical Studies. Hydroxychloroquine sulfate (HCQ) is an inhibitor of autophagy that inhibits the fusion of the autophagosome to the lysosome. *p < 0.05. CAS  Hepatobiliary Surg Nutr. Based on this data, inhibition of NET formation may also explain the previously recognized reduction in VTE rate. 18 Years and older   (Adult, Older Adult), Boston, Massachusetts, United States, 02115, Boston, Massachusetts, United States, 02214, Brian Wolpin, MD, MPH, Principal Investigator, Dana-Farber Cancer Institute. We have for the first time also provided evidence that these pathways play a role in human pancreatic cancer. Levels of circulating tissue factor, the initiator of extrinsic coagulation, were measured using ELISA. Gould TJ, Vu TT, Swystun LL, Dwivedi DJ, Mai SH, Weitz JI, et al. Waterfall plot demonstrating individual treatment response to gemcitabine/nab-paclitaxel with and without hydroxychloroquine in patients with elevated preoperative levels (e). © 2020 BioMed Central Ltd unless otherwise stated. The company’s cancer drug, devimistat, has received orphan status from the agency for treating clear-cell sarcoma, pancreatic cancer, and other diseases. Google ScholarÂ. Platelets were activated with collagen (2 μg/ml; ChronoLog) and aggregation was measured for 6 min at 37 °C with a stir speed of 1200 rpm and gain of 0.01. This phase I trial studies the best dose of hydroxychloroquine when given together with binimetinib in treating patients with KRAS gene mutated pancreatic cancer that has spread to other places in the body (metastatic). Part of These studies are designed to fail. This study reports correlative data from two clinical trials that registered with clinicaltrials.gov, NCT01128296 (May 21, 2010) and NCT01978184 (November 7, 2013). Blue = WT, Red = RAGE KO, Circle = Sham, Triangle = Tumor. Furthermore, RAGE KO mice, which have diminished NET formation, also had lower levels of serum tissue factor (Fig. 3b). Read our, ClinicalTrials.gov Identifier: NCT01273805, Interventional 2017;157:9–15. Blood. CAS  Data is reported as the area under the curve (AUC), which incorporates both the slope and amplitude of the aggregation curve. Women of child-bearing potential and men must agree to use adequate contraception prior to study entry and for the duration of study participation. Inhibiting NET formation by genetic depletion of PAD4 resulted in a decrease in serum tissue factor (Fig. 3a). Google ScholarÂ. Neutrophil and fibrinogen conjugates in the pancreatic tumor microenvironment. Additionally, the 90 day postoperative reduction in VTE occurred despite HCQ stopping at time of surgery. Swamydas M, Luo Y, Dorf ME, Lionakis MS. To elucidate the potential mechanism of decreased platelet aggregation after CQ treatment, we treated PAD4KO mice with CQ and found that it had minimal effect in these mice, suggesting that CQ mediates decreased platelet aggregation through inhibition of NETs (Fig. 4c). RAGE is a nucleic acid receptor that promotes inflammatory responses to DNA. Binimetinib may stop the growth of tumor cells … Martinod K, Demers M, Fuchs TA, Wong SL, Brill A, Gallant M, et al. *p < 0.05 vs. Sham, **p < 0.05 vs. Tumor. Furthermore, because autophagy is critical for NETs in pancreatic cancer, we investigated the use of the autophagy/NET inhibitor chloroquine to reverse NET mediated hypercoagulability in murine models and human patients. The datasets used and/or analyzed during the current study are available from the corresponding author on reasonable request. Meng H, Yalavarthi S, Kanthi Y, Mazza LF, Elfline MA, Luke CE, et al. Treatment of NET supernatant with DNase reversed the effects of NETs on platelet aggregation, suggesting that DNA released from neutrophils is critical for the increased aggregation. The team uncovered evidence to suggest that CQ and HCQ could be effective for the treatment of a number of cancers, including glioblastoma — … Mice were treated with oral chloroquine administered in the drinking water (0.5 mg/mL, MP Biomedicals, Solon, OH, USA). For the orthotopic pancreatic cancer model, wild type, RAGE KO and PAD4 KO mice were randomly allocated and injected with 1 × 106 Panc02 cells (National Cancer Institute repository, 2008) into the tail of the pancreas through a limited laparotomy. After initially being described in sepsis, neutrophil extracellular traps (NETs) were discovered in malignancy and promote tumor growth [28], development of metastases [29, 30] and serve as a potential contributor to cancer associated thrombosis [10].
