Hsp60 molecular anatomy and role in colorectal cancer diagnosis and treatment

2011

Quantitative changes in Hsp60 during the development of some tumors suggest that this chaperonin plays a role in carcinogenesis. A description of the specific role(s) of Hsp60 in tumor-cell growth and proliferation is still incomplete, but it is already evident that monitoring its levels and distribution in tissues and fluids has potential for diagnosis and staging, and for assessing prognosis and response to treatment. Although Hsp60 is considered an intramitochondrial protein, it has been demonstrated in the cytosol, cell membrane, vesicles, cell surface, extracellular space, and blood. The knowledge that Hsp60 occurs at all these locations opens new avenues for basic and applied research…

Chaperonology: The Third Eye on Brain Gliomas

2018

The European Organization for Research and Treatment of Cancer/National Cancer Institute of Canada Phase III trial has validated as a current regimen for high-grade gliomas (HGG) a maximal safe surgical resection followed by radiotherapy with concurrent temozolamide. However, it is essential to balance maximal tumor resection with preservation of the patient&rsquo

HSP-MOLECULAR CHAPERONES IN CANCER BIOGENESIS AND TUMOR THERAPY: AN OVERVIEW

2012

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 …

Current regimen for high-grade gliomas is maximal safe surgical resection followed by external beam radiotherapy with concurrent temozolamide. Maximal tumor resection, however, must be balanced with preservation of the patient’s neurological function. A crucial prognostic factor in oncological neurosurgery is the extent of resection. Several studies have addressed the importance of extent of resection in gliomas surgery. Despite development in the fields of pre operative and intraoperative neuroimaging and neuromonitoring have ameliorated the survival rate and the quality of life for patients affected by high grade gliomas, the clinical outcome of patients with such gliomas remains extremel…
