Nutrition in inflammatory bowel disease patients
Inflammatory Bowel Diseases (IBD) is a chronic disorder characterized bya relapsing-remitting course, which alternates between active and quiescent states, ultimately impairing a patient's quality of life. The two main types of IBD are Crohn's disease (CD) and ulcerative colitis (UC). CD shows a transmural granulomatous inflammation that can involve any segment of the intestine affecting all layers of the intestinal wall while UC is limited to the mucosa and superficial sub-mucosa of the colon. In physiologial conditions the gut is costantly exposed to various antigens, commensal microflora and pathogens and the inflammatory response is finely balanced. Anyhow in some individuals with genet…
Introduzione a Biologia dello Sviluppo. Principi generali dello Sviluppo.
Con il termine “sviluppo” ci riferiamo fondamentalmente all’insieme degli eventi attraverso cui da un uovo fecondato si genera un organismo pluricellulare, composto da differenti tipi cellulari, organizzati in tessuti ed organi, ciascuno deputato a svolgere una specifica funzione (di sostegno, di protezione, di nutrizione, di locomozione, sensoriale, riproduttiva, ecc.) e con una sua ben precisa forma tridimensionale e localizzazione spaziale rispetto alle altre strutture che compongono l’organismo.
Human dental pulp cell apoptosis: immunohistochemical study after applying orthodontic traction.
The aim of this study was to compare human dental pulp stress and programmed cell death after 3 and 6 months of orthodontic treatments by assessing the degree of apoptosis and related proteins. Human dental pulps were collected from twenty young patients orthodontically treated by Straight Wire technique. Samples were fixed, paraffin-embedded and processed for histology and immunohistochemistry using anti-heat shock protein 60 kDa (Hsp60), -caspase 3, -caspase 9, and -PCNA antibodies, as well as TUNEL reactions. Moreover, we performed immunoprecipitation for Hsp60 and caspase 3, and for Hsp60 and caspase 9, from paraffin extracted tissues. Increased levels of both caspases and Hsp60 occurre…
Heat shock protein 60 levels in tissue and circulating exosomes in human large bowel cancer before and after ablative surgery.
BACKGROUND: Heat shock protein 60 (Hsp60) is a chaperonin involved in tumorigenesis, but its participation in tumor development and progression is not well understood and its value as a tumor biomarker has not been fully elucidated. In the current study, the authors presented evidence supporting the theory that Hsp60 has potential as a biomarker as well as a therapeutic target in patients with large bowel cancer. METHODS: The authors studied a population of 97 subjects, including patients and controls. Immunomorphology, Western blot analysis, and quantitative real-time polymerase chain reaction were performed on tissue specimens. Exosomes were isolated from blood and characterized by electr…
The value of immunohistochemical research on PCNA, p53 and heat shock proteins in prostate cancer management: a review.
This review addresses the significance of the expression of proliferating cell nuclear antigen (PCNA), p53 and some heat shock proteins (Hsps) in prostate carcinoma (PC). In fact, PCNA and p53 are two widely discussed tools in PC diagno- sis, mainly because of the controversy regarding the signifi- cance of their expression during prostate cancer development and progression. At the same time, only few studies have shown the potential role of Hsps in carcinogenesis and their overexpression in pre-neoplastic and neoplastic lesions of the prostate. We briefly describe the physiological roles of Hsps in normal cells, and the significance of their immunohistochem- ical detection in PC as well as…
HSP-MOLECULAR CHAPERONES IN CANCER BIOGENESIS AND TUMOR THERAPY: AN OVERVIEW
Molecular chaperones, many of which are heat-shock proteins (HSPs), are an important class of molecules with various functions. Pathological conditions in which chaperones become etiological and/or pathogenic factors are called chaperonopathies, and are classified into by defect, by excess, and by "mistake". In the latter case, the chaperone is structurally and functionally normal but paqrtecipates in pathwais that favor diseases, aòlthough in some cases the chaperone may have post-translational modifications that may lead it to change its location and function and, thus, to become pathogenic. For example, HSP-chaperones are involved in acrcinogenesis in various ways, so that some forms of …
