Freeze-fracture cytochemistry allows visualization of cellular and molecular characteristics of biomembranes in situ. In this review, we discuss freeze-fracture cytochemistry with special reference to a new cytochemical labeling of replicas, the detergent-digestion fracture-labeling technique. In this procedure, unfixed cells are rapidly-frozen, freeze-fractured, and physically stabilized by ev...
Erythrocytic nuclear alterations have been considered as an indicative of organism's exposure to genotoxic agents. Due to their close relationship among their frequencies and DNA damages, they are considered excellent markers of exposure in eukaryotes. However, poor data has been found in literature concerning their genesis, differential occurrence and their life span. In this study, we use mar...
conclusions the expression of recombinant calprotectin, as an effective protein, can help in diagnosis or treatment of inflammatory and cancer processes in the future. furthermore, ca2+ induced a partial change in secondary and tertiary structure of calprotectin subunits and this change is probably necessary for protein dimerization. results interaction of s100a8 and s100a9 in the presence of c...
Introduction: Proliferation of cancer cells and the potential of metastasis depend on the activity of different biomarkers such as proliferative ones. Proliferative biomarkers including ki-67, cyclin E1, cyclin D1, p27, and p21 were analyzed through immunohistochemistry (IHC) in previous studies. Methods: The current study aimed at investigating the utilizing role of RT-PCR in studying prolife...
breast cancer is the most important and prevalent cancer in women that can be managed if detected in the early stages. recently, there has been much focus on the use of epigenetic changes such as dna methylation in early detection of cancer. as recent research has put forth dok7 cpg island methylation as an epimarker, in the present study, using a quantification method, a cohort of iranian spor...
multiple sclerosis is a chronic inflammatory disease of the central nervous system characterized by a complex immune response. because of the complex nature of ms pathogenesis, a panel of biomarkers derived from different platforms will be required to reflect disease-related alterations. monitoring and evaluation of molecules associated with the pathogenesis of the disease would provide useful ...
