Proteolysis is an irreversible posttranslational modification affecting each and every protein from its biosynthesis to its degradation. Limited proteolysis regulates targeting and activity throughout the lifetime of proteins. Balancing proteolysis is therefore crucial for physiological homeostasis. Control mechanisms include proteolytic maturation of zymogens resulting in active proteases and the shut down of proteolysis by counteracting endogenous protease inhibitors. Beyond the protein level, proteolytic enzymes are involved in key decisions during development that determine life and death – from single cells to adult individuals. In particular, we are becoming aware of the subtle role ...
Aim: The purpose of this study is to enhance the understanding of bladder cancer and the role of cancer-associated fibroblasts (CAFs) in its progression. We aim to identify CAF-specific biomarkers and develop a prognostic prediction model based on CAFs, thereby contributing to the advancement of treatment strategies and the identification of prognostic and predictive biomarkers for bladder cancer. Method: We employed single-cell RNA sequencing to detect biomarkers for CAFs in bladder cancer cells. Bladder cancer cohorts were categorized into low- and high-CAF groups using the ssGSEA algorithm. The study also explored the association between CAF-related scores, immune-related cells, and immun...
Current knowledge in Cancer Cell Biology aims to facilitate the design of more precise and non-invasive methods for early cancer cell detection, as well as more effective therapeutic interventions
This book summarizes all new data obtained after development of methods of Golgi complex sub fractionation, molecular biology and microscopy. It collects the full range of expertise, different points of view and different approaches. The book is devoted to molecular modes of the function of the Golgi apparatus as a whole, taking into account all experimental data. The book aims to make the functional organization of the Golgi apparatus more understandable.
The proteolytic enzymes have an essential function in all cells. Their activities are regulated by the rate of synthesis, activation of proenzymes and by the rate of synthesis of their inhibitors. They are synthesized in ribosomes like any other proteins and transported to various storage organelles or secreted from the cells and are activated in the pericellular space or in interstitium. Various cells and tissues have their characteristic enzyme patterns which serve their specific functions. Proteolytic enzymes take part and often have a regulatory role in numerous phases of cell function, e.g. cell division, migration, apoptotic as well as necrotic cell death etc. Diseases in which proteolysis has been subject of active research are e.g. cancer metastasis, viral infections, e.g. HIV, and Alzheimer's disease. They are also an essential part in any tissue remodelling, wound healing, throughout the kingdom of fauna and flora.
Pancreatic ductal adenocarcinoma is a highly aggressive malignancy with a poor prognosis. Effective treatment with acceptable outcomes is yet to be found, with chemo- and radioresistance comprising major impediments towards this goal. Although upfront surgery is the established therapeutic approach for resectable and borderline resectable disease, neoadjuvant treatment has recently monopolized the interest in clinical trials. This also applies to locally advanced pancreatic adenocarcinomas that could potentially be rendered operable. Chemotherapy and chemoradiotherapy are the most utilized therapeutic modalities in the neoadjuvant setting, while immunotherapy and targeting agents have been gaining significant attention. This critical review focuses on the clinical experience gained from retrospective and phase II/III randomized trials, reporting on the outcomes of neoadjuvant chemotherapy and chemoradiotherapy for pancreatic adenocarcinoma. Moreover, the ongoing trials, including those that involve immunotherapy and targeting agents, are summarized.
An action-oriented and radically hopeful field guide to the underground, patient-led revolution for better health and health care. Anyone who has fallen off the conveyer belt of mainstream health care and into the shadowy corners of illness knows what a dark place it is to land. Where is the infrastructure, the information, the guidance? What should you do next? In Rebel Health, Susannah Fox draws on twenty years of tracking the expert networks of patients, survivors, and caregivers who have come of age between the cracks of the health care system to offer a way forward. Covering everything from diabetes to ALS to Moebius Syndrome to chronic disease management, Fox taps into the wisdom of th...
"Personalized Medicine investigates the recent movement for patients' involvement in how they are treated, diagnosed, and medicated; a movement that accompanies the increasingly popular idea that people should be proactive, well-informed participants in their own healthcare. While it is often the case that participatory practices in medicine are celebrated as instances of patient empowerment or, alternatively, are dismissed as cases of patient exploitation, Barbara Prainsack challenges these views to illustrate how personalized medicine can give rise to a technology-focused individualism, yet also present new opportunities to strengthen solidarity. Facing the future, this book reveals how medicine informed by digital, quantified, and computable information is already changing the personalization movement, providing a contemporary twist on how medical symptoms or ailments are shared and discussed in society"--Provided by publisher.
About two centuries after the communication by Sir Percival Pott that the "chimney sweeper disease" was a cancer and its suggestion that active compounds of soot were the causative agents, and about one century after the description of urinary bladder cancer in dye workers, an enormous number of substances have been synthesized and have probably come into contact with man. Research in cancer prevention is of primary importance, and may receive continuous support from new discoveries on cancer etiology and pathogenesis. If one accepts the multistage model of chemical carcinogenesis, one has also to accept that many events occur between the contact of carcino genic compounds and their specific targets and the development of a clinically recognizable neoplasm. Thus, animal studies become essential to elucidate the different steps by which chemical carcinogens induce neoplasia. The analysis of these steps and the comparative evaluation of experimental models is essential to an understanding of pathogenesis.
