Available in PDF, EPUB and Kindle. Book excerpt: The meeting on experimental hepatocarcinogenesis which took place in Spa, Belgium at the end of May 1987 was the Second European Meeting. About 100 scientists, mostly from Europe but also from the United States, met there for three days in a very friendly atmosphere to exchange knowledge and ideas on experimental and human liver carcinogenesis. The main topics discussed during the meeting included general reviews on hepatocarcinogenesis, experimental models of hepa tocarcinogenesis, biology of hepatocarcinogenesis, and in vitro studies in hepatocarcinogenesis. They are all covered by the various chapters of this proceedings volume, which reflects the present state of knowledge in this important field of cancer research. The final aim of that research is to understand the basic mechanisms of carcinogenesis. The liver offers a parti cularly interesting tool to reach such a goal. Indeed, its biochemistry, its morphology, and its physiology are very diverse, but relatively well known. Various protocols have been developed to produce hepatocellular carcinomas or other malignant tumors. Their appearance is most often preceded by phenotypically altered foci and nodules which have been isolated and characterized. The major cell populations of normal, neoplastic, and malignant livers have been cultivated.

Available in PDF, EPUB and Kindle. Book excerpt: The Role of Cell Types in Hepatocarcinogenesis provides the first comprehensive, review and analysis of cell precursor relationships believed to be important in the development of hepatocellular carcinoma and other types of nonmesenchymal liver tumors. The book focuses on cell lineages in liver development and neoplastic formation in both experimental animal models and humans. It also critically reviews current information supporting the existence of a "facultative liver stem cell" and its potential role as an alternative cell of origin in the genesis of various hepatic neoplasms, including hepatocellular carcinoma. Other significant topics covered include cellular and viral oncogenes, p53 gene and growth factors in hepatocarcinogenesis, and the use of newly developed transgenic animal and cell culture models designed for investigating the pathogenesis of hepatocellular carcinoma. Numerous figures and tables illustrate difficult concepts, and an extensive listing of references is included. The Role of Cell Types in Hepatocarcinogenesis is a practical reference volume that basic and clinical researchers in liver carcinogenesis, development, and differentiation will find useful in their day-to-day work.

This book was released on 2023-05-25 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hepatocytes and bile ductular cells possess stem-like potential in restoring liver tissue. This was derived from rat and mouse injury models such as (a) partial hepatectomy by surgery; (b) acute carbon tetrachloride intoxication; © injuries by D-galactosamine (GalN) or by N-nitrosomorpholine (NNM); (d) experimental hepatocarcinogenesis with NNM using different doses. Liver parenchyma was restored by adult hepatocytes after partial hepatectomy as well as after carbon tetrachloride intoxication. Concurrently, hepatocytes resumed synthesis of alpha-1-fetoprotein (AFP) which depended to a high degree on the animal species and strains used in that studies. In contrast to this way of regeneration, liver repair after heavy injuries by agents such as GalN and NNM was initiated by oval cell proliferation deriving from ductular epithelial cells of the canaliculi of HERING (canals of Hering, intrahepatic bile ductules) as sources of endogenous progenitors. Progenitor populations reach levels of differentiation with fetal gene reactivation and significant AFP expression. Proliferating oval cells operated as transit and amplification compartment during liver regeneration. Oval cell proliferation and concurrent AFP synthesis occurred also in the early stages of hepatocarcinogenesis when the carcinogen NNM was applied in toxic doses. The histologic features compared to those seen in GalN intoxication. NNM carcinogenicity was of concern for both oval cells and adult hepatocytes with risks of transformation and malignant development. At the cancer stage, carcinomas either synthesizing AFP or not can be found side by side in the same liver. AFP expression by cancer cells seems to be a special attribute to differentiation stages in carcinogenesis. Clonality, maturation arrest and retro-differentiation feature cells with high autonomy.

Available in PDF, EPUB and Kindle. Book excerpt: Mycotoxins, from the Greek "mukes" referring to fungi or slime molds and toxin from the Latin "toxicum" referencing a poison for arrows, have earned their reputation for being potentially deleterious to the health and well being of a consuming organism, whether it be animal or human. Unfortunately, mycotoxins are a ubiquitous factor in the natural life cycle of food producing plants. As such, control of the potential impact of mycotoxins on food safety relies heavily upon accurate analysis and surveys followed by commodity segregation and restricted use or decontamination through processing. The purpose of this book is to provide the most comprehensive and current information on the topic of mycotoxins and assuring food safety. Chapters represented in the book reflect such diverse topics ranging from occurrence and impact, analysis, reduction through processing and plant breeding, toxicology and safety assessments to regulatory perspectives. Authors represent a range of international perspectives.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] Hepatocellular carcinoma (HCC) is the major malignancy complicating chronic liver disease. New therapies for the prevention of HCC are required due to the limited success and high tumour recurrence rates of existing treatments. Emerging evidence suggests that HCC arise from the transformation of adult liver progenitor cells (LPCs), which have the capacity to differentiate into hepatocytes and biliary cells during liver regeneration. LPC activation precedes neoplasia in experimental hepatocarcinogenesis. LPCs share antigenic epitopes with HCCs, including α-fetoprotein (AFP) and M2- pyruvate kinase (M2PK). In animal models of hepatocarcinogenesis, attenuation of the LPC response reduces the incidence of HCC following prolonged liver injury via a tumour necrosis factor (TNF) dependent mechanism. As TNF is a pro-inflammatory cytokine, these data suggest that anti-inflammatory agents may be effective in inhibiting LPC activation and hepatocarcinogenesis. Cyclo-oxygenase-2 (COX-2) is an inducible enzyme that mediates the production of many prostaglandins during inflammation and carcinogenesis. Recent investigations show that the administration of selective COX-2 inhibitors (SC2Is) may reduce the incidence of a variety of tumours including breast, colon and skin. The broad aim of this thesis was to conduct a series of detailed studies on the effects of a SC2I on LPC activation and the hepatic pathologies associated with hepatocarcinogenesis in order to test the hypothesis that S2CIs may be a beneficial therapy that can reduce liver injury and pre-neoplastic changes in the choline-deficient, ethionine supplemented (CDE) murine model of hepatocarcinogenesis. Administration of a SC2I (SC-236) significantly inhibited a variety of hepatic cell populations that expand during the first month of the CDE mouse model of hepatocarcinogenesis (a choline deficient, ethionine supplemented diet). Numbers of M2PK-positive LPCs (which are more hepatocytic in morphology and are also COX-2 positive) and inflammatory cells were all significantly reduced by SC-236. In contrast, numbers of A6-positive LPCs (which are more biliary cell-like in morphology and do not express COX-2) were unchanged. ... In summary, these data suggest that COX-2 inhibitors such as SC-236 inhibit LPC activation and a variety of pre-neoplastic liver pathologies as a result of COX-2 dependent and independent mechanisms that may be mediated through inhibition of Akt phosphorylation and induction of apoptosis. Moreover, SC2Is may be useful as preventative treatment strategies for HCC in patients with chronic liver disease.

Available in PDF, EPUB and Kindle. Book excerpt: Limiting genome replication to once per cell cycle is vital for maintaining genome stability. Although polyploidization is of physiologically importance for several specialized cell types, inappropriate polyploidization is believed to promote aneuploidy and transformation. A growing body of evidence indicates that the surveillance mechanisms that prevent polyploidization are frequently perturbed in cancers. Progress in the past several years has unraveled some of the underlying principles that maintain genome stability. This book brings together leaders of the field to overview subjects relating to polyploidization and cancer.

Available in PDF, EPUB and Kindle. Book excerpt: The contents of this book are the proceedings of the ACS symposium, "Fumonisins in Food," which was held April 4-6, 1995, at the American Chemical Society National Meeting in Anaheim, CA. This symposi"Qm, which was international in scope, brought together researchers from diverse backgrounds in academia, government, and industry. Thirty-three speakers discussed topics ranging from the analysis offumonisins to toxicology and regulatory aspects. The fumonisins became the spotlight of mycotoxin research in 1988, when re searchers at the South African Medical Research Council isolated and structurally charac terized the fumonisins. Since 1988, there has been an explosion in the numbers of papers dealing with fumonisin-related topics. The interest in the fumonisins has arisen for several reasons. First, fumonisins are found in measurable concentrations in corn grown throughout the world. Second, these compounds have been implicated as the causative agents in a variety of naturally occurring animal diseases. Finally, there is speCUlation that fumonisins may in part be responsible for the high incidence of esophageal cancer in regions of the world in which corn is the staple grain.
