Differentiation-dependent glycosylation of cells in squamous cell epithelia detected by a mammalian lectin [PDF]

, 2002
The squamous stratified epithelia contain a proliferative (harboring mitotic activity) and a differentiating compartment. Due to the potential of protein-carbohyd rate interactions to regulate cellular activities we introduced a mammalian lectin to cyto-

Ki-67 expression in pulmonary tumors [PDF]

Translational Lung Cancer Research, 2016
Ki-67 was introduced more than two decades ago as a measure of the tumor proliferative fraction , in the need for a useful marker that might help clinicians to guide therapy and predict the prognosis of patients with cancer (1). Although several methods have been used to determine the tumor proliferative fraction in the research setting, the only ...

P63 and Ki-67 expression in radicular cyst

Journal of Oral Biology and Craniofacial Research, 2023
The aim of the current study was to identify the expression of P63 and its relation to odontogenic epithelial cell proliferation, severity of the inflammatory infiltrate and size of radicular cysts (RCs).In this retrospective cross-sectional study, 30 cases of paraffin-embedded RCs were randomly selected from the archive.

Localisation of the Ki-67 antigen within the nucleolus: Evidence for a fibrillarin-deficient region of the dense fibrillar component [PDF]

, 1996
The Ki-67 antigen is detected in proliferating cells in all phases of the cell division cycle. Throughout most of interphase, the Ki-67 antigen is localised within the nucleolus.

Frequency of Chlamydia trachomatis infection in cervical intraepithelial lesions and the status of cytological p16/Ki-67 dual-staining [PDF]

, 2017
Background: Chlamydia trachomatis (Ct) is not a disease subject to mandatory reporting in Brazil, and the prevalence rate of this genital infection varies according to the region in which studies are conducted, as well as by the detection technique ...

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Hypoxia and hyperglycaemia determine why some endometrial tumours fail to respond to metformin [PDF]

, 2020
High expression of Ki67, a proliferation marker, is associated with reduced endometrial cancer-specific survival. Pre-surgical metformin reduces tumour Ki-67 expression in some women with endometrial cancer. Metformin's anti-cancer activity may relate to

Immunohistochemical detection of Hsp90 and Ki-67 in pterygium [PDF]

Diagnostic Pathology, 2013
To examine the immunohistochemical expression of heat shock protein 90 (Hsp90) and Ki-67 protein in human pterygium.Tissues obtained during pterygium surgery of 15 patients who underwent the bare-sclera procedure and 10 normal conjunctivae were studied. All of these pterygia were primary ones. Recurrent pterygia were excluded.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
