We find enrichment in the Her2 subtype and ductal carcinoma among those observations exhibiting greater cluster correspondence across expression and CNA data.
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.
Negative staining for pan-ras, H-ras, and N-ras in cases with wild-type K-ras genes suggests that alternative routes of ras gene alteration are not operative in IPMT or ductal carcinoma.
Twelve of thirteen cases (92%) of intraductal papillary mucinous tumor of the pancreas, confirmed histologically (9 adenomas and 4 carcinomas), and 26 of 43 cases (60%) of ductal carcinoma showed specific K-ras gene mutations in the pancreatic juice.
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.

We analyzed 25 cases of archived, paraffin-embedded breast carcinoma (ductal) for Feulgen stain DNA analysis and MIB-1 immunohistochemistry using the CAS 200 Image Cytometer.

We describe the parental origin and functional characterization of a novel de novo BRCA2 splice site mutation found in a patient exhibiting a ductal carcinoma at the age of 40.
We investigated the correlations between growth patterns and E-cadherin expression by immunohistochemistry and the presence of mutations of exons 6-10 of the E-cadherin gene by PCR-SSCP, in 79 cases of invasive lobular and ductal breast cancer.
Nevertheless, it is unclear if SIRT1 affects the development of neoplastic lesions and whether metabolic gene expression is altered.To assess neoplastic lesion development, mice with a pancreas-specific loss of Sirt1 (Pdx1-Cre;Sirt1-lox) were bred into a KrasG12D mutant background (KC) that predisposes to the development of pancreatic intra-epithelial neoplasia (PanIN) and ductal adenocarcinoma (PDAC).
In conclusion, the XRCC1 genotype was found to be associated with ductal carcinoma histotypes and XPD genotype with low histological grade, which is the most frequent pattern of sporadic breast carcinomas.
Although, in IHC studies, nuclear BRAFV600E (VE1) protein expression was found in 14 (15%) of the analyzed cases: nine of 28 (32%) cases of pleomorphic adenoma, three of five (60%) cases of ductal carcinoma, one of nine (11%) case of mucoepidermoid carcinoma, and in one of five (20%) case of carcinoma ex pleomorphic adenoma.
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.
