Gene therapy prevents hepatic tumor initiation in murine glycogen storage disease type Ia at the tumor-developing stage.

J Inherit Metab Dis 2019 Jan 14. Epub 2019 Jan 14.

Section on Cellular Differentiation, Division of Translational Medicine, Eunice Kennedy Shriver National Institute of Child Health and Human Development.

Hepatocellular adenoma/carcinoma (HCA/HCC) is a long-term complication of glycogen storage disease type-Ia (GSD-Ia) which is caused by a deficiency in glucose-6-phosphatase-α (G6Pase-α or G6PC), a key enzyme in gluconeogenesis. Currently, there is no therapy to address HCA/HCC in GSD-Ia. We have previously shown that a recombinant adeno-associated virus (rAAV) vector-mediated G6PC gene transfer to 2-week-old G6pc-/- mice prevents HCA development. Read More

Colorectal Cancer: Causes and Evidence of Chemopreventive Treatments.

Curr Pharm Biotechnol 2018 12 25. Epub 2018 Dec 25.

Department of Engineering in Biomedical Systems, Faculty of Engineering, National Autonomous University of Mexico, Exterior Circuit, University City, 04510. Mexico.

Background: Colorectal cancer (CRC) is the second and third most frequent cancer in women and men, respectively; indeed, CRC is placed as the fourth world's most deadly cancer (after lung, liver, and stomach cancer). The incidence of CRC is strongly influenced by nutrition and the high fat/high carbohydrate Western-style diet. CRC is one of the most intensively studied cancer types, partly because of its high prevalence, but also because of the existence of its precursor lesions, tubular or villous adenomas, and more recently serrated adenomas.

Molecular Pathological Differences in Global Gene Expression between Two Sustained Proliferative Lesions, Nodular Regenerative Hepatocellular Hyperplasia and Hepatocellular Adenoma, in Mice.

Toxicol Pathol 2018 Dec 20:192623318810200. Epub 2018 Dec 20.

1 Division of Pathology, National Institute of Health Sciences, Kawasaki, Kanagawa, Japan.

Long-term exposure to piperonyl butoxide (PBO) induces multiple nodular masses along with hepatocellular tumors in the liver of mice. The histopathological features of the nodules led to our diagnosis of nodular regenerative hepatocellular hyperplasia (NRH). However, because of the lack of data on the biological characteristics of NRH, whether this lesion is truly nonneoplastic remains unknown. Read More

Colonoscopy attachments for the detection of precancerous lesions during colonoscopy: A review of the literature.

World J Gastroenterol 2018 Oct;24(37):4243-4253

Hepato-gastroenterology Unit, Second Department of Internal Medicine -Propaedeutic, Research Institute and Diabetes Center, Medical School, National and Kapodistrian University of Athens, ''Attikon" University General Hospital, Athens 12462, Greece.

Although colonoscopy has been proven effective in reducing the incidence of colorectal cancer through the detection and removal of precancerous lesions, it remains an imperfect examination, as it can fail in detecting up to almost one fourth of existing adenomas. Among reasons accounting for such failures, is the inability to meticulously visualize the colonic mucosa located either proximal to haustral folds or anatomic curves, including the hepatic and splenic flexures. In order to overcome these limitations, various colonoscope attachments aiming to improve mucosal visualization have been developed. Read More

Heterozygosity of Chaperone Grp78 Reduces Intestinal Stem Cell Regeneration Potential and Protects against Adenoma Formation.

Cancer Res 2018 Nov 19;78(21):6098-6106. Epub 2018 Sep 19.

Department of Gastroenterology and Hepatology, Tytgat Institute for Liver and Intestinal Research, University of Amsterdam, Amsterdam, the Netherlands.

Deletion of endoplasmic reticulum resident chaperone Grp78 results in activation of the unfolded protein response and causes rapid depletion of the entire intestinal epithelium. Whether modest reduction of Grp78 may affect stem cell fate without compromising intestinal integrity remains unknown. Here, we employ a model of epithelial-specific, heterozygous deletion by use of mice and organoids. Read More

Envoi Specialist Pathologists, Brisbane, Qld, Australia; Faculty of Medicine, University of Queensland, Brisbane, Qld, Australia.

Hepatocellular adenomas are benign liver lesions with a risk of rupture and malignant transformation. Various molecular subgroups have been identified which appear to have characteristic morphological and immunohistochemical features. We examined the morphology and immunohistochemical profile of a series of 121 HCA from 97 patients to identify the HCA subtypes present and determine the number at risk for malignant transformation according to the World Health Organization (WHO) criteria for hepatocellular adenomas.
