Polymorphisms in genes involved in the complex mechanisms of carcinogenesis may affect the susceptibility to cancer. The multifunctional cytokine tumor necrosis factor alpha (TNF alpha) has an important role in the pathogenesis of inflammatory, autoimmune and malignant diseases. It has a large spectrum of activities, including both antitumorigenic and protumorigenic. In recent years, several TN...
Microchimeric cells of fetal origin persistent in the maternal circulation post-partum are associated with protection against invasive breast cancer. Here using quantitative genomic methods, we evaluated for the presence of male fetal microchimerism in buffy coat cells from women with a prior history of breast carcinomas in situ (CIS) and in healthy controls. Fetal microchimerism was detected i...
t BackgroundBackground Ductal carcinoma in situ (DCIS) of the breast is a disorder that has become moree common since it may manifest as microcalcifications that can be detected by screeningg mammography. Since selected women with invasive cancer can be treated safelyy with breast-conservation therapy it is paradoxical that total mastectomy has remainedd the standard treatment for DCIS. We did ...
mri of the breast has evolved as a non-invasive imaging modality and is ideally suited for several indications e.g. pre-operative staging and screening in women at increased risk for breast cancer. the widespread use opens also the discussion on over-diagnosis if only 20 - 30 out of 100 mri - guided breast biopsies lead to the diagnosis of breast cancer. thus mri based strategies are needed to ...
Overview Women in the United States have a 12.3% estimated lifetime risk for developing breast cancer (i.e., 1 in 8 women).1 In 2009, an estimated 194,290 cases of invasive breast cancer (192,370 women and 1919 men) and 62,280 cases of female carcinoma in situ of the breast will be diagnosed in the United States, with 40,610 deaths from invasive breast cancer predicted.2 However, mortality from...
We present a label-free, chemically-selective, quantitative imaging strategy to identify breast cancer and differentiate its subtypes using coherent anti-Stokes Raman scattering (CARS) microscopy. Human normal breast tissue, benign proliferative, as well as in situ and invasive carcinomas, were imaged ex vivo. Simply by visualizing cellular and tissue features appearing on CARS images, cancerou...
NFAT1 is a transcription factor that elicits breast carcinoma cells to become invasive, thus contributing to metastasis. The molecular mechanisms by which NFAT1 operates in this respect are still poorly known. Here, we report that NFAT1 increases lipocalin 2 (LCN2) mRNA and protein expression by binding to specific sites in the LCN2 gene promoter region. We show that the LCN2 protein is require...
Invasive lobular carcinoma of the breast has similar patterns of metastatic disease when compared to invasive ductal carcinoma; however, lobular carcinoma metastasizes to unusual sites more frequently. We present a 65-year-old female with a history of invasive lobular breast carcinoma (T3N3M0) treated with modified radical mastectomy and aromatase-inhibitor therapy who underwent a surveillance ...
There are several mutations and structural variations common to breast cancer. Many of these genomic changes are thought to represent driver mutations in oncogenesis. Less well understood is how and when these changes take place in breast cancer development. Previous studies have identified gene rearrangements in the microtubule-associated serine-threonine kinase (MAST) and NOTCH gene families ...
The vacuolar (H+)-ATPases (V-ATPases) are a family of ATP-driven proton pumps that acidify intracellular compartments and transport protons across the plasma membrane. Previous work has demonstrated that plasma membrane V-ATPases are important for breast cancer invasion in vitro and that the V-ATPase subunit a isoform a3 is upregulated in and critical for MDA-MB231 and MCF10CA1a breast cancer c...
