Detecting proliferating cell nuclear antigen in archival rodent tissues.
The detection of proliferating cell nuclear antigen (PCNA), an endogenous cell replication marker, has lacked sensitivity in paraffin-embedded archival tissues fixed in formalin. An enhanced immunohistochemical procedure to detect PCNA has been successfully applied to rat and mouse tissues. Tissue sections are heated in a microwave oven in the presence of an antigen-retrieval solution of heavy-...
متن کاملProliferating cell nuclear antigen expression in childhood acute leukemia.
Proliferating cell nuclear antigen (PCNA) is a 36-Kd nuclear protein, identified as the auxiliary protein of DNA polymerase delta, that is upregulated in activated proliferating cells from a variety of tissues and species, including human lymphocytes. We have examined by two-dimensional polyacrylamide gel electrophoresis the expression of PCNA in various subtypes of childhood acute leukemia and...
متن کاملProliferating cell nuclear antigen expression in papillary thyroid carcinoma.
AIMS To correlate the expression of proliferating cell nuclear antigen (PCNA) with various clinicopathological features of papillary thyroid carcinoma. METHODS Sections from 131 formalin fixed, paraffin wax embedded papillary thyroid carcinomas were stained with a monoclonal antibody (PC10) directed against PCNA using the avidin-biotin immunoperoxidase (ABC) method. PCNA immunoreactivity was ...
متن کاملComparison of the Expression Level of P53 and Proliferating Cell Nuclear Antigen (PCNA) Genes in the Inflamed and Non-Inflamed Dentigerous Cysts
Background & Aims: The role of P53 and proliferating cell nuclear antigen (PCNA) genes in inflamed and non-inflamed odontogenic cysts is related to cell proliferation but it is unclear. The aim of this study was immunohistochemical evaluation of P53 and PCNA expression in inflamed and non-inflamed dentigerous cysts Methods: In the present study, 23 dentigerous cysts (12 inflamed and 11 non-infl...
متن کامل[Expression of nuclear Ki-67 antigen in prostatic high grade intraepithelial neoplasia and prostatic carcinoma].
BACKGROUND/AIM Prostatic intraepithelial high grade neoplasia (PINHG) is accepted as preneoplastic lesion in prostatic carcinoma. One of the fundamental events in early oncogenesis is the disruption of proliferative activity. One of the numerous regulatory proteins is Ki-67 expressed in all proliferating cells. Index Ki-67 is considered to have prognostic significance. The aim of the study was ...
