Download or read book Identification of CDH11 as a Candidate Tumor Suppressor in Retinoblastoma and Characterization of Its Role in Retina and Retinoblastoma written by Mellone Noelene Marchong and published by . This book was released on 2007 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since Kundson's two hit hypothesis of the retinoblastoma tumor susceptibility gene in 1971 and the subsequent cloning of RB1 in 1986 and 1987, pRB has been the highlight of cancer research. It represents the prototypical model for inherited cancers and has since lead to better understanding of cancer genetics. The disease is unique in that its initiating mutational events are known, loss of both alleles of RB1, mutational events 1 and 2 (M1 and M2). Investigation of mutational events, M3-Mn, that lead to its progression will be useful for better understanding of retinoblastoma tumorigenesis, which can ultimately translate to the development of new and better therapeutics that can be used to halt retinoblastoma progression at a very early stage. Loss of chromosomal region 16q22 is a significant genomic change recognized not only in retinoblastoma but in numerous other cancers. Using loss of heterozygosity (LOB) and quantitative multiplex PCR (QM-PCR) techniques on a total of 76 retinoblastoma tumors we were able to narrow down the genomic region of loss on chromosome 16q22. We identified a gene, CDH11, to be a candidate tumor suppressor in retinoblastoma, as it was found to display copy number loss in 58% of 71 tumors and protein expression loss in tumors of both human and murine retinoblastoma. To study the role of cadherin-11 in retinogenesis, I compared developing retinae of Cdh11+/+, Cdh11+/- and Cdh11-/- mouse littermates, and report that Cdh11 plays a subtle role during murine retinogenesis, whereby it supports the development of the retinoblastoma susceptibility cells in the transgenic SV40 large T-antigen mouse model of retinoblastoma (TAg-RB). I also report that retinoblastoma tumors in mice with mutant alleles of Cdh11 grow faster than tumors in mice with normal Cdh11 alleles. These results herein, concur with characteristics identifying tumor suppressor genes. Thus, I provide compelling evidence to support a tumor suppressor role for Cdh11 in retinoblastoma progression.

Download or read book Methylation of the Retinoblastoma Tumor Suppressor by SMYD2 and Functional Interactions Between Retinoblastoma and C MYC in a Mouse Model of Hepatocellular Carcinoma written by Louis Alexander Saddic (III.) and published by Stanford University. This book was released on 2011 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The retinoblastoma tumor suppressor RB is a central cell cycle regulator. Here we demonstrate that RB can be methylated by SMYD2 at lysine 860, a highly conserved and novel site of modification. This methylation event occurs in vitro and in cells and is regulated during cell cycle progression, cellular differentiation, and in response to DNA damage. Furthermore, we show that RB mono-methylation at lysine 860 provides a direct binding site for the methyl-binding domain of the transcriptional repressor L3MBTL1. This modification may be crucial for regulating the function of RB as a tumor suppressor. Inactivation of RB and activation of the MYC family of oncogenes are frequent events in a large spectrum of human cancers. Here, we sought to also test whether loss of RB function would affect cancer development in a mouse model of c-MYC-induced hepatocellular carcinoma (HCC). We found that RB inactivation has minimal effects on the cell cycle, cell death, and differentiation features of liver tumors driven by increased levels of c-MYC. However, combined loss of RB and activation of c-MYC led to an increase in polyploidy in mature hepatocytes before the development of tumors and a trend for decreased survival after cancer initiation.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of the entire field of cadherin research and provides the current basic concept of cadherins. Cadherins have been widely accepted as key regulators of animal development and physiological functions, and it also has become clear that they play essential roles in various human diseases. With contributions by leading scientists, the book covers various aspects of the cadherin superfamily including the history of cadherin research, basic properties of classical cadherins as well as non-classical cadherins, cadherin-associated proteins, and the roles of cadherins in health and diseases. In addition, the book presents some contradictory results and important unanswered questions, and the authors propose their working hypotheses or future directions, to inspire future studies. This volume enables graduate students and young researchers to learn the basics and gain a comprehensive image of the cadherin superfamily, and experts in the field will easily find various topics of interest in relevant areas of study. Additionally, a list of cadherin-related diseases is included for quick reference to cadherins in human diseases.
Download or read book New Aspects of Cancer Stem Cell Biology written by Ugo Cavallaro and published by MDPI. This book was released on 2020-11-23 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cancer stem cell (CSC) paradigm represents one of the most prominent breakthroughs of the last decades in tumor biology. CSCs are that subpopulation within a tumor that can survive conventional therapies and as a consequence are able to fuel tumor recurrence. Nevertheless, the biological characteristics of CSCs and even their existence, remain the main topic among tumor biologists debates. The difficulty in achieving a better definition of CSC biology may actually be explained by the plasticity of such a cell subpopulation. Indeed, the emerging view is that CSCs represent a dynamic “state” of tumor cells that can acquire stemness-related properties under specific circumstances, rather than referring to a well-defined group of cells. Regardless of their origin, it is clear that designing novel antitumor treatments based on the eradication of CSCs will only be possible upon unraveling the biological mechanisms that underlie their pathogenic role in tumor progression and therapy resistance. The Special Issue on “New aspects of cancer stem cell biology: implications for innovative therapies” aims at highlighting recent insights into CSC features that can make them an attractive target for novel therapeutic strategies.
Download or read book Cancer Genes Volume 2 written by Satish Ramalingam and published by Bentham Science Publishers. This book was released on 2023-08-17 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer Genes is a comprehensive list of the most critical genes known to contribute to cancer imitation and progression. The book delves into their location on each chromosome, providing valuable insights into the mechanisms of cancer gene dysregulation and genetic mutations which provide cancer cells with an advantage during each stage of tumorigenesis. The reference will familiarize readers with the location of cancer genes and equip them with the necessary information to identify relevant gene expression targets for research aimed at preventing the disease. The book is divided into two volumes focusing on cancer-causing genes found in chromosome pairs 1-12 (volume 1), and chromosomes13-23 (volume 2). A key feature of the book is a detailed reference list for advanced readers. The compilation is therefore a quick and handy reference on cancer-causing genes for researchers, medical professionals, and anyone interested in understanding the genetic basis of cancer.

Download or read book Human Skin Cancers written by Miroslav Blumenberg and published by BoD – Books on Demand. This book was released on 2018-05-02 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human skin cancers, the most common type of tumors, represent a significant health burden. The deadliest is unquestionably melanoma. Half of melanomas have an activating mutation in the BRAF gene, prompting development of novel drugs, vemurafenib and dabrafenib, specifically targeting mutated BRAF. Trametinib and cobimetinib, which block MEK, a BRAF effector protein, have been used in combination with BRAF inhibitors. A promising new melanoma treatment is immunotherapy, approach that boosts patient's own immune system to attack cancer. Pembrolizumab and nivolumab inhibit PD-1, whereas Ipilimumab targets CTLA-4, another immunity check point, to boost the immune response. Here we focus on pathways, mechanisms, targets and treatments of human skin cancers, with particular emphasis on the new developments in the research on melanomas.
