The analyses using human breast ductal carcinoma tissues exhibited that the expression of ZNF224 and miR-663a was increased in cancer compared to non-cancer region.
Vascular permeability factor mRNA was expressed at a low level by normal duct epithelium but was expressed at high levels in tumor cells in all cases of comedo-type DCIS, infiltrating ductal carcinoma, and metastatic ductal carcinoma.
Immunohistochemical analysis further established that the expression of monoglyceride lipase was restricted to ductal breast cancer and present in 77% of these tumors, while Vav1 was restricted to MCB and present in 60% of tumors.
The results suggest an association between loss of p63 expression and progression of breast ductal carcinoma. p63 immunostaining might be of assistance for distinguishing invasive ductal carcinoma from ductal carcinoma in situ or rare questionable ductal hyperplastic lesions, leading to correct therapy clinically.
Immunocytochemical analysis of p63 and 34βE12 in fine needle aspiration cytology specimens for breast lesions: a potentially useful discriminatory marker between intraductal papilloma and ductal carcinoma in situ.
Eighteen randomly selected cases of invasive breast carcinoma (IBC) of luminal type, two cases of in situ duct carcinoma (DCIS/DIN), and 20 specimens of normal and benign breast tissues were studied.All cases were immunostained for p63.
The aim of this study was to investigate an association between three polymorphisms of the UBC9 gene: c.73G>A (rs11553473), c.430T>G (rs75020906) and g.1289209T>C (rs7187167) and a risk of ductal breast cancer occurrence.
Immunocytochemistry using HeLa cells transiently expressing FLAG-tagged fortilin and immunohistochemistry using human breast ductal carcinoma tissue and anti-fortilin antibody both showed that fortilin is predominantly localized in the nucleus.

To assess the role of p53 in infiltrative ductal breast carcinoma among Iranian patients, p53 protein expression and p53 gene mutations were studied by immunohistochemical analysis and single-strand conformation polymorphism, respectively.
When combined with the Frt-STOP-Frt KrasG12D and p53Frt mouse lines, simultaneous Pdx1FlpO activation of mutant Kras and deletion of p53 results in the spectrum of pathologic changes seen in PDAC, including PanIN lesions and ductal carcinoma.
To clarify whether p53 protein expression is involved in multistep carcinogenesis or the progression of mammary ductal carcinoma, we investigated p53 protein expression in 83 invasive ductal carcinomas (IDC), 10 IDC with a predominant intraductal component, 13 non-invasive ductal carcinoma (NIDC), 16 atypical ductal hyperplasia (ADH) and 39 benign epithelial hyperplasia (EH), using immunohistochemistry.
In both univariate and multivariate Cox regression analyses, TNC was an independent poor prognostic factor for overall survival (OS) in breast ductal carcinoma patients.
