The cell proliferation antigen Ki-67 organises heterochromatin

open access: yeseLife, 2016
Antigen Ki-67 is a nuclear protein expressed in proliferating mammalian cells. It is widely used in cancer histopathology but its functions remain unclear. Here, we show that Ki-67 controls heterochromatin organisation.

Cigarette Smoking, Oncogenic Human Papillomavirus, Ki-67 Antigen, and Cervical Intraepithelial Neoplasia [PDF]

open access: bronzeAmerican Journal of Epidemiology, 2004
Although cigarette smoking has been identified as a cofactor for cervical neoplasia, it is not clear whether smoking exerts an early or late effect on the evolution of human papillomavirus (HPV)-related lesions. A case-control study of Washington State women who presented for routine gynecologic care from 1997 to 2001 was conducted. All women underwent

Expression of Metallothionein I/II and Ki-67 Antigen in Graves' Disease [PDF]

open access: bronzeAnticancer Research, 2018
The expression of metallothionein I/II (MT-I/II) was examined in thyroids of Graves' disease (GD) and nodular goiter (NG) patients to determine its role as a potential marker of proliferation and autoimmune inflammation in the thyroid.MT-I/II and Ki-67 antigen expression was studied using immunohistochemistry in 72 GD and 24 NG patients.MT-I/II ...

Expression of Ki-67—–A Proliferation-Associated Antigen—in Prostatic Cancer

open access: diamondActa Oncologica, 1991
The expression of the proliferation-associated antigen Ki-67 was studied in human prostatic cancer. The antigen was analyzed with an immuno-histochemical technique in TUR specimens. A correlation was seen between Ki-67 positivity and differentiation grade. All TUR specimens (15/15) with poorly differentiated carcinomas expressed the antigen. Moderately
