Proliferating 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 کاملEpidermal growth factor receptor and proliferating cell nuclear antigen in astrocytomas.
AIMS The involvement of various growth factors, growth factor receptors and proliferative markers in the molecular pathogenesis of astrocytic neoplasms are being studied extensively. Epidermal Growth Factor Receptor (EGFR) gene overexpression occurs in nearly 50% of cases of glioblastoma. Since EGFR and proliferating cell nuclear antigen (PCNA) are involved in mitogenic signal transduction and ...
متن کاملUp-regulation by progesterone of proliferating cell nuclear antigen and epidermal growth factor expression in human uterine leiomyoma.
Uterine leiomyoma is the most common smooth muscle cell tumor of the myometrium. Estrogen and progesterone (P4) are believed to be physiological regulators of leiomyoma growth. We recently showed that Bcl-2 protein, an apoptosis-inhibiting gene product, was abundantly expressed in leiomyoma relative to its expression in the normal myometrium and that Bcl-2 protein expression in cultured leiomyo...
متن کاملpRb2/p130, Vascular Endothelial Growth Factor, p27, and Proliferating Cell Nuclear Antigen Expression in Hepatocellular Carcinoma: Their Clinical Significance
Hepatocarcinoma (HCC) is the fifth most common cancer, with more than one million fatalities occurring annually worldwide. Multiple risk factors are associated with HCC disease etiology, the highest incidence being in patients with chronic hepatitis B virus and hepatitis C virus, although other factors such as genetic makeup and environmental exposure are involved. Multiple genetic alterations ...
