When gene expression data are compiled from different sources, basal-like tumors in TNBC consistently cluster within a group that express CK5
, 6, 14, 17, and caveolin1/2, as well as c-kit and P-cadherin (15,42).

All immunohistochemical staining was performed at our histology laboratory (The University of Texas Health Science Center at San Antonio Histology Laboratory, San Antonio, Texas) using 2 dual-antibody cocktails for DG3 + CK5
/napsin A and p40/ TTF-1 (prediluted; napsin A and p40, rabbit polyclonal; DG3 + CK5
and TTF-1, mouse monoclonal; Biocare Medical, Concord, California).
These, in combination with some of the more traditional markers such as TTF-1, CK5
and p63, may enable much more confident identification of SqCC and LADC.
The chapter on mammospheres and breast carcinomas describes the basal like phenotype of breast CSC with expression of CD44, CK5
These cadmium-transformed breast epithelial (CTBE) cells displayed characteristics of basal-like breast carcinoma, including ER-(X negativity and HER2 (human epidermal growth factor receptor 2) negativity, reduced expression of BRCA1 (breast cancer susceptibility gene 1), and increased CK5
(cytokeratin 5) and p63 expression.
Powerful 1 GHz PowerPC-based CK5
supports VxWorks(R) and Linux operating systems
The genes EGFR (4 of 23; 17%), Trop2 (2 of 23; 9%), ER-b (1 of 23; 4%), CK5
(1 of 23; 4%); and CEA (0 of 23; 0%) were infrequently expressed in patient samples and were not expressed in the leukocytes.
helps to define the integrity of the basal cell layer, so the pathologist can confirm the existence of high-grade prostatic intraepithelial neoplasia (HGPIN); even if cancer is not found in the biopsy, ERG positive HGPIN gives strong support for the existence of prostate adenocarcinoma within a few millimeters of the biopsy due to a 'field affect.
Immunohistochemistry studies showed that the lining epithelium was positive for CK7 and focally for CK5
The monoclonal antibody 34[beta]12 targets cytoplasmic highmolecular-weight cytokeratin filaments in basal cells of the benign prostatic glands, namely CK1, CK5
, CK10, and CK14.
6,7) The myoepithelial component is highlighted by p63, smooth muscle myosin heavy chains, CK5
, CD10, calponin, actin, and S100.
