Human dental pulp cell apoptosis: immunohistochemical study after applying orthodontic traction.
2012
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…
Hsp27 and Hsp60 in human submandibular salivary gland: Quantitative patterns in healthy and cancerous tissues with potential implications for differe…
2021
Tumors of the submandibular salivary gland (SMG) are uncommon but sufficiently frequent for the physician to consider them in routine examinations and for the pathologist to be prepared to differentiate them from other tissue abnormalities. However, scarcity of specimens makes training difficult, a situation compounded by the lack of accepted universal diagnostic guidelines. Furthermore, there is little information on the chaperone system (CS) of the gland, despite the increasing evidence of its participation in carcinogenesis as a biomarker for diagnosis and patient follow up, and in the mechanisms by which the tumor cells thrive. We are investigating this aspect of various tumors, and her…
Chaperonin Hsp60 and Cancer Therapies
2020
The heat shock protein 60 (Hsp60) is a chaperonin belonging to the chaperoning (chaperone) system that typically contributes to protein homeostasis inside mitochondria, but also plays various non-canonical roles unrelated to protein quality control beyond the organelle. Chaperonopathies are disorders in which chaperones play an etiologic-pathogenic role and contribute to the onset/progression of disease. Hsp60 chaperonopathies by mistake are diseases in which the chaperonin is apparently normal (as far as it can be determined with current methodologies) but it actively contributes to pathology, for example in certain types of cancer, and autoimmune and chronic inflammatory disorders. In cer…
Design and synthesis of high affinity compounds for the Hsp60 expression control in carcinogenic processes
2013
First observed in cells exposed to high temperatures, Heat shock proteins (Hsps) are nowadays considered the most important cell “chaperone” complexes over-expressed in response to a number of cell stress stimuli.1 The chaperone activity is the main function of the eukaryotic Heat shock protein 60 kDa (Hsp60), involved in the capture and refold of unfolded or misfolded proteins. Additional roles in signal transduction,2 senescence activation3 and apoptosis4 have been ascribed to cytosolic Hsp60. During the carcinogenIc process, in vivo studies demonstrated increased levels of human Hsp60 in several organs, such as uterine exocervix,5 large bowel,6 and prostate.6 In this context, our study …

STRESS, CHAPERONI MOLECOLARI E MALATTIE INFIAMMATORIE CRONICHE DELL'INTESTINO
2011
This brief article is focused on HSP60, a very important molecular chaperon for cell surviving, involved in the pathogenesis of several degenerative, autoimmune, and neoplastic disorders. Recent reports confer unravelling role in IBD pathogenesis. involvement of HSP60 in CD and UC development has been recently confirmed. in fact HSP60 levels increase in mucosal epithelium and also in lamina propria of affected subjects.
