EGFR-targeted molecular imaging of colorectal tumors: detection and treatment evaluation of tumors in animal models.

Cancer Sci 2019 Apr 11. Epub 2019 Apr 11.

Department of Gastroenterology and Oncology, University of Tokushima, Faculty of Medicine Graduate School of Medical Sciences, Tokushima, Tokushima, Japan.

To overcome the problem of overlooking colorectal tumors, a new and highly sensitive modality of colonoscopy is needed. Moreover, it is also important to establish a new modality to evaluate the viable tumor volume in primary lesions of colorectal cancer (CRC) during chemotherapy. Therefore, we performed molecular imaging of colorectal tumors targeting epidermal growth factor receptor (EGFR), which is highly expressed on tumor cells, for evaluating chemotherapeutic efficacy and for endoscopic detection of colorectal adenomas.

Intratumoral F-FLT infusion in metabolic targeted radiotherapy.

EJNMMI Res 2019 Apr 11;9(1):33. Epub 2019 Apr 11.

Department of Nuclear Medicine and Radiobiology, Faculty of Medicine and Health Sciences, Université de Sherbrooke, Sherbrooke, QC, Canada.

Background: The goal of targeted radiotherapy (TRT) is to administer radionuclides to tumor cells, while limiting radiation exposure to normal tissues. 3'-Deoxy-3'-[F]-fluorothymidine (F-FLT) is able to target tumor cells and emits a positron with energy appropriate for local (~ 1 mm range) radiotherapy. In the present work, we investigated the potential of TRT with a local administration of F-FLT alone or in combination with 5-fluorouracil (5FU), which acts as a chemotherapeutic agent and radiosensitizer.

Farnesoid X receptor represses matrix metalloproteinase 7 expression, revealing this regulatory axis as a promising therapeutic target in colon cancer.

J Biol Chem 2019 Apr 9. Epub 2019 Apr 9.

University of Maryland School of Medicine, United States.

The farnesoid X receptor (FXR) is a member of the nuclear receptor superfamily of bile acid-activated transcription factors and an important regulator of cell proliferation, apoptosis, and Wnt signaling. Down-regulated expression of FXR plays an important role in some malignancies such as colon cancer, and in rodent models of intestinal neoplasia, FXR knockout increases the size and number of colon tumors. These previous observations implicate FXR as a tumor suppressor, but the underlying molecular mechanisms are unclear. Read More

Class 1, 2 and 3 BRAF mutated metastatic colorectal cancer: a detailed clinical, pathological and molecular characterization.

Clin Cancer Res 2019 Apr 9. Epub 2019 Apr 9.

Department of Medicine, University of Padua.

Purpose BRAF mutations are grouped in activating RAS-independent signaling as monomers (class 1 - V600E) or as dimers (class 2 - codons 597/601), and RAS-dependent with impaired kinase activity (class 3 - codons 594/596). While clinical, pathological and molecular features of V600E BRAF mutated metastatic colorectal cancer (mCRC) are well known, limited data are available from the two other classes. Experimental Design Data from 117 BRAF (92 class 1, 12 class 2, and 13 class 3) mutated mCRC patients were collected. Read More

A Therapeutic Strategy for Chemotherapy-Resistant Gastric Cancer via Destabilization of Both β-Catenin and RAS.

Cancers (Basel) 2019 Apr 8;11(4). Epub 2019 Apr 8.

Translational Research Center for Protein Function Control, Yonsei University, Seoul 03722, Korea.

Treatment of advanced gastric cancer patients with current standard chemotherapeutic agents frequently results in resistance, leading to poor overall survival. However, there has been no success in developing strategies to overcome it. We showed the expression levels of both β-catenin and were significantly increased and correlated in tissues of 756 gastric cancer (GC) patients and tissues of primary- and acquired-resistance patient-derived xenograft tumors treated with 5-fluorouracil and oxaliplatin modulated with leucovorin (FOLFOX).
