Effects of Serum Deprivation on Ki‐67‐reactive Antigen

Acta Pathologica Japonica, 1989
In order to elucidate the relationship between the level of cellular Ki‐67‐reactive antigen and cell proliferation activity, the effects of serum deprivation on the antigen expression and cell proliferation of HeLa cells were investigated using flow cytometry.

Expression of p53, MDM2 protein and Ki-67 antigen in recurrent meningiomas

Journal of Neuro-Oncology, 1998
Association of p53 gene abnormalities with tumor progression and prognosis of many neoplasms has been demonstrated, but little is known about the clinical significance of p53 abnormalities in meningiomas. The significance of p53 protein expression in recurrent meningiomas and its relationships with MDM2 protein and proliferation activity were ...

Effects of Raloxifene on Ki-67 and CD34 Antigen Expression in Breast Cancer

Gynecologic and Obstetric Investigation, 2008
<i>Background:</i> The aim of this study was to evaluate the effect of raloxifene on CD34 and Ki-67 antigen expression in breast cancer specimens from postmenopausal women. <i>Methods:</i> Sixteen postmenopausal patients with operable, stage II (≥3 cm), estrogen receptor-positive breast cancer, who took 60 mg of raloxifene daily

The proteasome controls the expression of a proliferation-associated nuclear antigen Ki-67

Journal of Cellular Biochemistry, 2000
The proteasome is a protease complex responsible for rapid, selective, and irreversible removal of regulatory proteins, as well as many other cellular proteins. In this study, we have demonstrated that a proliferation-associated nuclear protein Ki-67 depended on the proteasome for its rapid degradation.

Ki-67 Antigen Staining as an Adjunct to Identifying Cervical Intraepithelial Neoplasia

Journal of Lower Genital Tract Disease, 1997
The purpose of the work was to determine the feasibility and predictive value of Ki-67 immunostaining of cervical cytology and the detection of cervical dysplasia. Air-dried cervical smears were stained with MIB-1 antibody to identify the Ki-67 antigen. Nuclear decoration in abnormal squamous nuclei determined immunoreactivity.

Kinetic aspects of Ki-67 antigen expression in a normal cell line

Virchows Archiv B Cell Pathology Including Molecular Pathology, 1991
Using a normal cell line derived from a human fetus, the disappearance and reappearance of the Ki-67-reactive antigen following modification of the cell cycle was observed and estimated immunohistologically. It was found that G1/G0 arrest induced by serum deprivation resulted in loss of the antigen in 24 h in all but a few (usually less than 10%) of ...

Ki-67 antigen expression and growth pattern of basal cell carcinomas

Archives of Dermatological Research, 1993
The expression and location of the Ki-67 antigen was investigated in 62 basal cell carcinomas (BCC) using immunostaining techniques (PAP and APAAP) on cryostat sections. The tumor samples were classified into three groups according to microarchitecture (nodular, superficial or fibrosing).

Hereditary Gingival Fibromatosis and Expression of Ki‐67 Antigen: A Case Report

Journal of Periodontology, 2003
Background: Hereditary gingival fibromatosis (HGF) is a fibrotic enlargement of the gingiva. The mechanism that leads to the accumulation of abnormal amounts of gingival tissue in HGF is still unknown. The aim of this report was to present the clinical and histopathologic characteristics of a patient with gingival fibromatosis and to evaluate the ...

Ki 67 - ANTIGEN IN CHOROID PLEXUS PAPILLOMAS AND CARCINOMAS

1997
Reactivity of Ki 67-antigen was tested in six choroid plexus tumours (three papillomas and three carcinomas) in purpose to evaluate the proliferative potential of each tumour. All evaluated tumours were diagnosed in male children ageing from few months to 12 years except one papilloma which was diagnosed in 23 years old female.

[Flow cytometric analysis of Ki-67 reactive antigen].

Nihon rinsho. Japanese journal of clinical medicine, 1992
Monoclonal antibody Ki-67 is a useful and easy means for evaluating cell proliferative activity. Furthermore, it appears to provide valuable prognostic informations in some neoplastic diseases. However, almost all studies on solid tumors were performed only by microscopic observation using immunohistochemistry, and not by flow cytometry. Therefore, the
