Assessment Of Mucin 13 (Muc13) As An Imaging Target For Guiding Colorectal Cancer Treatment: A Pathway Towards Theranostic Development, Ryan P. Coll, Aiko Yamaguchi, Jianbo Wang, Xiaoxia Wen, Denise Hernandez, Subhash C. Chauhan, H. Charles Manning

Research Symposium

Background: A theranostic strategy combining diagnostic imaging and targeted therapy in a single regimen is proposed for improved management and treatment of colorectal cancer (CRC). Increased specificity in detection by the noninvasive imaging technique positron emission tomography (PET) can be achieved by radiolabeling antibodies (Abs) designed to target tumor-associated antigens with increased expression post-translational modifications present in cancer cells. In this study, an Ab designed to target the transmembrane glycoprotein mucin 13 (MUC13) was radiolabeled with the positron-emitting radionuclide zirconium-89 (⁸⁹Zr) for PET imaging of a xenograft mouse model of CRC. Specified uptake of this radioimmunoconjugate was observed …

Identifying The Best Cutoff Value Of The Fecal Occult Blood Immunochemical Test In The Detection Of Advanced And Neoplastic Colorectal Lesions [Identificación Del Mejor Punto De Corte De La Prueba Inmunoquímica De Sangre Oculta En Heces En La Detección De Lesiones Colorrectales Avanzadas Y Neoplásicas], Patricia Gaggero, Eduardo Fenocchi, Cecilia Silva, Juan C.

Objective: Screening is an effective tool for detecting colorectal lesions in asymptomatic subjects. There is a positive correlation between fecal immunochemical test (FIT) values and the size of tumors. Despite the efficacy of screening, the detection of colorectal cancer (CRC) remains low. The primary objective was to evaluate the best FIT cutoff value for detecting advanced adenomas and CRC among individuals at average risk in a country with a high incidence and morbidity from CRC.

Methods: This observational and prospective study analyzed consecutive cases in 1461 asymptomatic subjects with a positive FIT (≥ 100 ng hemoglobin [Hb]/ mL) referred for …

Mutational And Expression Analysis Of Fbxw7 Gene In Colorectal Cancer Patients Among North Indian Population, Laraib Uroog

Research Symposium

Background: Colorectal cancer is the third most common cancer worldwide with the incidence rate of 1.8 million (10.2%) (GOBOCON-2018). CRC is endemic to Kashmir Valley due to both, kangri use and non-veg food habit. The current study was designed to explore the possible correlation between that FBXW7 and colorectal cancer progression.

Methods: FBXW7 gene mutations and expression was analyzed in 173 colorectal carcinoma tissues along with the adjacent non-cancerous matched tissues using polymerase chain reaction-single stranded confirmation polymorphism assay. Gene expression analysis was conducted using qRT-PCR, western blot and IHC.

Results: In total, six mutations were found …

Mucin Muc13 And Yap1 Correlate With Poor Survival In Colorectal Cancer, Sudhir Kotnala, Anupam Dhasmana, Kyle Doxtater, Meena Jaggi, Murali M. Yallapu, Manish Tripathi, Subhash C. Chauhan

Research Symposium

Background: Metastatic disease contributes to over 90% of cancer-associated deaths. Colorectal cancer (CRC), the second lethal malignancy, has the greatest incidence and mortality rates in the Southern United States. Over 40-50% of CRC patients acquire metastasis at some point throughout their disease's progression. CRC survival rate drops from 90%-14% when the disease is confined within the colon and therefore “early diagnosis” becomes imperative to determine timely and quality treatments. We have identified that MUC13 protein translocate to nucleus along with transcription factor Yes-Associated Protein 1 (YAP1) during anchorage independent conditions (metastatic phenotype). YAP1 is known to be overexpressed in CRC …

Generalized Linear Mixed Model Analysis Of Urban-Rural Differences In Social And Behavioral Factors For Colorectal Cancer Screening, Ke-Sheng Wang, Xuefeng Liu, Muyiwa Ategbole, Xin Xie, Ying Liu, Chun Xu, Changchun Xie, Zhanxin Sha

Health & Biomedical Sciences Faculty Publications and Presentations

Objective: Screening for colorectal cancer (CRC) can reduce disease incidence, morbidity, and mortality. However, few studies have investigated the urban-rural differences in social and behavioral factors influencing CRC screening. The objective of the study was to investigate the potential factors across urban-rural groups on the usage of CRC screening.

Methods: A total of 38,505 adults (aged ≥40 years) were selected from the 2009 California Health Interview Survey (CHIS) data - the latest CHIS data on CRC screening. The weighted generalized linear mixed-model (WGLIMM) was used to deal with this hierarchical structure data. Weighted simple and multiple mixed logistic regression analyses …
