Download or read book Multifunctional Role of Pancreatic Differentiation 2 PD2 in Pancreatic Cancer written by Arokia Priyanka Vaz and published by . This book was released on 2015 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer is a devastating disease that claims the lives of countless people due to its uncontrolled growth pattern. Among various cancers, pancreatic cancer is one of the most lethal cancers due to its aggressive nature, lack of early symptoms and resistance to chemotherapy. The molecular profile of this deadly malignancy is not completely understood. Malignancy arises due to loss or gain of function in genes involved in cell cycle progression leading to disruption of tightly regulated transitions. In addition the evolving concept of cancer throws light on a small population of cells within the tumor known as the cancer stem cells (CSCs) or tumor-initiating cells that are resistant to all drugs treatment and contributes towards tumor initiation and recurrence. Several studies have been carried out to identify specific markers for the cancer stem cell population including that of pancreatic cancer. Pancreatic Differentiation 2 (PD2) or human Polymerase Associated Factor 1 (hPaf1) is an important component of the multifunctional PAF1 complex initially identified to play a crucial role in transcriptional elongation of genes. During the last decade, several papers on PD2 showed that it is a multifaceted molecule playing roles in cell cycle regulation, stem cell maintenance, histone methylation, chromatin remodeling and acinar-to-ductal metaplasia. In this dissertation, the first goal was to investigate the role of PD2 in pancreatic cancer stem cells. Initially, we analyzed the expression and function of PD2 in pancreatic cancer stem cells isolated from pancreatic cancer cell lines, Kras (G12D); Pdx1 (Cre)(KC), Kras (G12D); Trp53 (R172H/+.); Pdx1(Cre) (KPC) mouse models and human pancreatic tumors. Furthermore, the expression of PD2 was significantly higher in CSCs isolated from pancreatic cancer cells along with CSC markers. These cells were shown to exhibit a cobblestone appearance, increased tumorsphere formation and significant tumor growth, characteristic of the CSC phenotype. interestingly, PD2 was found to be specifically overexpressed in a subpopulation of cells within mouse KC, KPC and human pancreatic tumors, which co-express CSC markers. The drug resistance property was impaired upon knockdown of PD2 with simultaneous alteration in the CSC phenotype and reduction in CD133 and MDR2 gene expression. Overall, my study identified that PD2 has a role in self-renewal and drug resistance of pancreatic CSCs. The second part of my dissertation was primarily focused at exploring the functional role of PD2 in pancreatic cancer cells. The ectopic overexpression of PD2 resulted in increased growth rate of tumor cells both in vitro and in vivo. Overexpression of PD2 led to increased growth, colony formation and migration. Interestingly, elevated expression of PD2 also increased the percentage of CSCs. Furthermore, in vivo studies revealed that PD2 overexpression leads to increased tumor volume and metastasis to distant secondary sites. These results were corroborated at the protein level where elevated expression of PD2 led to the up-regulation of c-Myc which is an important player in tumorigenesis and metastasis. In addition, the expression of PD2 in pancreatic cancer tissues and in vitro pancreatic progression model was elucidated. We demonstrated that the expression of PD2 was increased in the ducts present in the pancreatic cancer tissues when compared to the normal tissues. Likewise, the expression of PD2 was elevated in the transformed Human Pancreatic Nestin expressing (HPNE) cells when compared to the untransformed HPNE cells. Understanding the role of PD2 through cell lines led to my next aim to generate PD2 conditional knockout mice in order to substantiate our earlier work in cancer stem cells and acinar to ductal metaplasia during PC initiation. The animal model would be an important resource for understanding the role of PD2 in detail. Taken together, our findings demonstrate that PD2 is an essential member of the oncogene family that plays a significant role in facilitating drug resistance and cancer stem cell maintenance thereby acting as a positive regulator of cancer.
Download or read book Heat Shock Proteins in Cancer written by Stuart K. Calderwood and published by Springer Science & Business Media. This book was released on 2007-09-09 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heat shock proteins are emerging as important molecules in the development of cancer and as key targets in cancer therapy. These proteins enhance the growth of cancer cells and protect tumors from treatments such as drugs or surgery. However, new drugs have recently been developed particularly those targeting heat shock protein 90. As heat shock protein 90 functions to stabilize many of the oncogenes and growth promoting proteins in cancer cells, such drugs have broad specificity in many types of cancer cell and offer the possibility of evading the development of resistance through point mutation or use of compensatory pathways. Heat shock proteins have a further property that makes them tempting targets in cancer immunotherapy. These proteins have the ability to induce an inflammatory response when released in tumors and to carry tumor antigens to antigen presenting cells. They have thus become important components of anticancer vaccines. Overall, heat shock proteins are important new targets in molecular cancer therapy and can be approached in a number of contrasting approaches to therapy.

Download or read book Endoplasmic Reticulum Stress in Health and Disease written by Patrizia Agostinis and published by Springer Science & Business Media. This book was released on 2012-08-13 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Endoplasmic Reticulum (ER) is an organelle with extraordinary signaling and homeostatic functions. It is the organelle responsible for protein folding, maturation, quality control and trafficking of proteins destined for the plasma membrane or for secretion into the extracellular environment. Failure, overloading or malfunctioning of any of the signaling or quality control mechanisms occurring in the ER may provoke a stress condition known as ‘ER stress’. Accumulating evidence indicates that ER stress may dramatically perturb interactions between the cell and its environment, and contribute to the development of human diseases, ranging from metabolic diseases and cancer to neurodegenerative diseases, or impact therapeutic outcome. This book primarily focuses on the pathophysiology of ER stress. It introduces the molecular bases of ER stress, the emerging relevance of the ER-mitochondria cross-talk, the signaling pathways engaged and cellular responses to ER stress, including the adaptive Unfolded Protein Response (UPR), autophagy as well as cell death. Next the book addresses the role of ER stress in physiology and in the etiology of relevant pathological conditions, like carcinogenesis and inflammation, neurodegeneration and metabolic disease. The last chapter describes how ER stress pathways can be targeted for therapeutic benefit. Altogether, this book will provide the reader with an exhaustive view of ER stress biology and the latest insights in the role of ER stress in relevant human diseases.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of the multifaceted field of protease in the cellular environment and focuses on the recently elucidated functions of complex proteolytic systems in physiology and pathophysiology. Given the breadth and depth of information covered in the respective contributions, the book will be immensely useful for researchers working to identify targets for drug development. Multidisciplinary in scope, the book bridges the gap between fundamental and translational research, with applications in the biomedical and pharmaceutical industry, making it a thought-provoking read for basic and applied scientists engaged in biomedical research. Proteases represent one of the largest and most diverse families of enzymes known, and we now know that they are involved in every aspect of a given organism’s life functions. Under physiological conditions, proteases are regulated by their endogenous inhibitors. However, when the activity of proteases is not correctly regulated, disease processes such as tumour progression, vascular remodelling, atherosclerotic plaque progression, ulcer, rheumatoid arthritis, Alzheimer’s disease and inflammation can result. Many infective microorganisms require proteases for replication or use them as virulence factors, which has facilitated the development of protease-targeted therapies for a variety of parasitic diseases.
