| digestive system diagram unlabeled: The Exocrine Pancreas Stephen Pandol, 2011 The secretions of the exocrine pancreas provide for digestion of a meal into components that are then available for processing and absorption by the intestinal epithelium. Without the exocrine pancreas, malabsorption and malnutrition result. This chapter describes the cellular participants responsible for the secretion of digestive enzymes and fluid that in combination provide a pancreatic secretion that accomplishes the digestive functions of the gland. Key cellular participants, the acinar cell and the duct cell, are responsible for digestive enzyme and fluid secretion, respectively, of the exocrine pancreas. This chapter describes the neurohumoral pathways that mediate the pancreatic response to a meal as well as details of the cellular mechanisms that are necessary for the organ responses, including protein synthesis and transport and ion transports, and the regulation of these responses by intracellular signaling systems. Examples of pancreatic diseases resulting from dysfunction in cellular mechanisms provide emphasis of the importance of the normal physiologic mechanisms. |

| digestive system diagram unlabeled: Toxicology in the Use, Misuse, and Abuse of Food, Drugs, and Chemicals European Society of Toxicology. Meeting, 1983-08 Many chemotherapeutic agents introduced for use in humans are carcinogenic in laboratory animals (Conklin et al. 1965; Shimkin et al. 1966; Griswold et al. 1968; Harris 1976). However, initially their beneficial effect in disseminated cancer was of such short duration that the inevitable death of the patient from his primary disease precluded any clinical manifestation of the carcinogenic potential. During the last decade, chemotherapy has radically changed the outlook for many patients with cancer. Combinations of drugs, administered as the primary treatment, have resulted in high rates of cure in patients with disseminated malignancies, such as stage IV Hodgkin's disease or childhood acute lymphocytic leukemia. In other disseminated forms of neoplasia, induction of a remission, a substantial palliation and a prolongation of survival have been achieved. In many instances of localised disease, where surgery with or without radiotherapy are the primary form of treatment, anticancer drugs have been used with success as adjuvant therapy for distant microscopic disease. With these spectacular achievements, secondary malignancies, in particular acute non-lymphocytic leukemia (ANLL), has become of major concern. Incidence Acute leukemia is the most frequent form of secondary neoplasia in patients treated for cancer (Penn 1981). In one large series, 5. 9% of all ANLL could be attributed to previous chemotherapy (Kapadia et al. 1980). |

| digestive system diagram unlabeled: Intracellular Protein Degradation A.J. Rivett, 1998-08-07 This volume brings together a set of reviews that provide a summary of our current knowledge of the proteolytic machinery and of the pathways of protein breakdown of prokaryotic and eukaryotic cells. Intracellular protein degradation is much more than just a mechanism for the removal of incorrectly folded or damaged proteins. Since many short-lived proteins have important regulatory functions, proteolysis makes a significant contribution to many cellular processes including cell cycle regulation and transciptional control. In addition, limited proteolytic cleavage can provide a rapid and efficient mechanism of enzyme activation or inactivation in eukaryotic cells. In the first chapter, Maurizi provides an introduction to intracellular protein degradation, describes the structure and functions of bacterial ATP-dependent proteases, and explores the relationship between chaperone functions and protein degradation. Many of the principles also apply to eukaryotic cells, although the proteases involved are often not the same. Interestingly, homologues of one of the bacterial proteases, Ion protease, have been found in mitochondria in yeast and mammals, and homologues of proteasomes, which are found in all eukaryotic cells (see below), have been discovered in some eubacteria. Studies of proteolysis in yeast have contributed greatly to the elucidation of both lysosomal (vacuolar) and nonlysosomal proteolytic pathways in eukaryotic cells. Thumm and Wolf (chapter 2) describe studies that have elucidated the functions of proteasomes in nonlysosomal proteolysis and the contributions of lysosomal proteases to intracellular protein breakdown. Proteins can be selected for degradation by a variety of differen mechanisms. The ubiquitin system is one complex and highly regulated mechanism by which eukaryotic proteins are targetted for degradation by proteosomes. In chapter 3, Wilkinson reviews the components and functions of the ubiquitin system and considers some of the known substrates for this pathway which include cell cycle and transcriptional regulators. The structure and functions of proteosomes and their regulatory components are described in the two subsequent chapters by Tanaka and Tanahashi and by Dubiel and Rechsteiner. Proteasomes were the first known example of threonine proteases. They are multisubunit complexes that, in addition to being responsible for the turnover of most short-lived nuclear and cytoplasmic protein, are also involved in antigen processing for presentation by the MHC class I pathway. Recent studies reviewed by McCracken and colleagues (chapter 6) lead to the exciting conclusion that some ER-associated proteins are degraded by cytosolic proteasomes. Lysosomes are responsible for the degradation of long-lived proteins and for the enhanced protein degradation observed under starvation conditions. In chapter 7 Knecht and colleagues review the lysosomal proteases and describe studies of the roles of lysosomes and the mechanisms for protein uptake into lysosomes. Methods of measuring the relative contribution of different proteolytic systems (e.g., ubiquitin-proteasome pathway, calcium-dependent proteases, lysosomes) to muscle protein degradation, and the conclusions from such studies, are reviewed by Attai and Taillinder in the following chapter. Finally, proteases play an important role in signaling apoptosis by catalyzing the limited cleavage of enzymes. Mason and Beyette review the role of the major players, caspases, which are both activated by and catalyze limite proteolysis, and also consider the involvement of other protoelytic enzymes in this pathway leading cell death. |
