Worth A Pound Of Cure? Emerging Strategies And Challenges In Cancer Immunoprevention, Saurav D Haldar, Eduardo Vilar, Anirban Maitra, Neeha Zaidi

Faculty, Staff and Student Publications

Cancer immunoprevention applies immunologic approaches such as vaccines to prevent, rather than to treat or cure, cancer. Despite limited success in the treatment of advanced disease, the development of cancer vaccines to intercept premalignant states is a promising area of current research. These efforts are supported by the rationale that vaccination in the premalignant setting is less susceptible to mechanisms of immune evasion compared with established cancer. Prophylactic vaccines have already been developed for a minority of cancers mediated by oncogenic viruses (e.g., hepatitis B and human papillomavirus). Extending the use of preventive vaccines to non-virally driven malignancies remains an …

Prognostic Significance Of Trophoblastic Cell Surface Antigen 2 Expression And Pathologic Parameters In Patients With Ampullary Adenocarcinoma, Yujie Zhang, Hua Wang, Michael Overman, Matthew Hg Katz, Huamin Wang

Faculty, Staff and Student Publications

Trophoblastic cell surface antigen 2 (TROP2) has been reported to be up-regulated in several types of carcinomas and is associated with aggressive behavior and poor survival. However, TROP2 expression and its clinical significance in ampullary adenocarcinoma (AA) have not been investigated. We examined TROP2 expression by immunohistochemistry in 112 patients with AAs. The associations of TROP2 expression with clinicopathologic characteristics were evaluated by χ2 analyses or Fisher's exact tests. The associations of TROP2 expression and pathologic parameters with survival were evaluated by the Kaplan-Meier method and univariate and multivariate Cox regression analyses. Eighty-six AAs (76.8%) were positive for TROP2, which …

Making Waves: Integrating Wastewater Surveillance With Dynamic Modeling To Track And Predict Viral Outbreaks, Tin Phan, Samantha Brozak, Bruce Pell, Jeremiah Oghuan, Anna Gitter, Tao Hu, Ruy M Ribeiro, Ruian Ke, Kristina D Mena, Alan S Perelson, Yang Kuang, Fuqing Wu

Faculty, Staff and Student Publications

Wastewater surveillance has proved to be a valuable tool to track the COVID-19 pandemic. However, most studies using wastewater surveillance data revolve around establishing correlations and lead time relative to reported case data. In this perspective, we advocate for the integration of wastewater surveillance data with dynamic within-host and between-host models to better understand, monitor, and predict viral disease outbreaks. Dynamic models overcome emblematic difficulties of using wastewater surveillance data such as establishing the temporal viral shedding profile. Complementarily, wastewater surveillance data bypasses the issues of time lag and underreporting in clinical case report data, thus enhancing the utility and …

Trans-Pacific Multicenter Collaborative Study Of Minimally Invasive Proximal Versus Total Gastrectomy For Proximal Gastric And Gastroesophageal Junction Cancers, Naruhiko Ikoma, Travis Grotz, Hirofumi Kawakubo, Hyoung-Il Kim, Satoru Matsuda, Yuki Hirata, Atsushi Nakao, Loretta A Williams, Xin Shelley Wang, Tito Mendoza, Xuemei Wang, Brian D Badgwell, Paul F Mansfield, Woo-Jin Hyung, Vivian E Strong, Yuko Kitagawa

Faculty, Staff and Student Publications

Background: The current standard operation for proximal gastric and gastroesophageal junction (P/GEJ) cancers with limited esophageal extension is total gastrectomy (TG). TG is associated with impaired appetite and weight loss due to the loss of gastric functions such as production of ghrelin and with anemia due to intrinsic factor loss and vitamin B12 malabsorption. Theoretically, proximal gastrectomy (PG) can mitigate these problems by preserving gastric function. However, PG with direct esophagogastric reconstruction is associated with severe postoperative reflux, delayed gastric emptying, and poor quality of life (QoL). Minimally invasive PG (MIPG) with antireflux techniques has been increasingly performed by experts …

A Review Of Pulmonary Neutrophilia And Insights Into The Key Role Of Neutrophils In Particle-Induced Pathogenesis In The Lung From Animal Studies Of Lunar Dusts And Other Poorly Soluble Dust Particles, Chiu-Wing Lam, Vincent Castranova, Kevin Driscoll, David Warheit, Valerie Ryder, Ye Zhang, Patti Zeidler-Erdely, Robert Hunter, Robert Scully, William Wallace, John James, Brian Crucian, Mayra Nelman, Richard Mccluskey, Donald Gardner, Roger Renne, Roger Mcclellan

Faculty, Staff and Student Publications

The mechanisms of particle-induced pathogenesis in the lung remain poorly understood. Neutrophilic inflammation and oxidative stress in the lung are hallmarks of toxicity. Some investigators have postulated that oxidative stress from particle surface reactive oxygen species (psROS) on the dust produces the toxicopathology in the lungs of dust-exposed animals. This postulate was tested concurrently with the studies to elucidate the toxicity of lunar dust (LD), which is believed to contain psROS due to high-speed micrometeoroid bombardment that fractured and pulverized lunar surface regolith. Results from studies of rats intratracheally instilled (ITI) with three LDs (prepared from an Apollo-14 lunar regolith), …

Faculty, Staff and Student Publications

Understanding the effects of inflammation and cirrhosis on the regulation of drug metabolism during the progression of hepatocellular carcinoma (HCC) is critical for developing patient-specific treatment strategies. In this work, we created novel three-dimensional vascularized HCC-on-a-chips (HCCoC), composed of HCC, endothelial, stellate, and Kupffer cells tuned to mimic normal or cirrhotic liver stiffness. HCC inflammation was controlled by tuning Kupffer macrophage numbers, and the impact of cytochrome P450-3A4 (CYP3A4) was investigated by culturing HepG2 HCC cells transfected with CYP3A4 to upregulate expression from baseline. This model allowed for the simulation of chemotherapeutic delivery methods such as intravenous injection and transcatheter …

Identification Of New Aptamer Bc-3 Targeting Rps7 From Rapid Screening For Bladder Carcinoma, Yunyi Liu, Juan Li, Hailong Ou, Dan Qi, Bei Hu, Yuxi Xu, Jian Hu, Yi Xiong, Luling Xia, Jason H Huang, Xiaoxiao Hu, Erxi Wu

Faculty, Staff and Student Publications

Aptamers, short single DNA or RNA oligonucleotides, have shown immense application potential as molecular probes for the early diagnosis and therapy of cancer. However, conventional cell-SELEX technologies for aptamer discovery are time-consuming and laborious. Here we discovered a new aptamer BC-3 by using an improved rapid X-Aptamer selection process for human bladder carcinoma, for which there is no specific molecular probe yet. We show that BC-3 exhibited excellent affinity in bladder cancer cells but not normal cells. We demonstrate that BC-3 displayed high selectivity for tumor cells over their normal counterparts in vitro, in mice, and in patient tumor …
