Twenty novel chromene derivatives carrying different sulfonamide moieties (3-22) were designed and synthesized. All the newly prepared compounds were evaluated for their in vitro anticancer activity against breast cancer cell line (T47D). Most of the synthesized compounds showed good to moderate activity (IC50 = 8.8-108.9 μM), where compound 16 (IC50 = 8.8 μM) exhibited higher activity compared to doxorubicin (IC50 = 9.8 μM). In order to determine the mechanism of the anticancer activity in T47D cells, the effect of the most potent compounds (5-8, 11-14, and 16-18) on the aromatase activity was tested...

ECM1 overexpression is an independent predictor of poor prognosis in primary breast carcinomas, however the mechanisms by which ECM1 affects tumor progression have not been completely elucidated. ECM1 was silenced in the triple-negative breast cancer cell lines Hs578T and MDAMB231 using siRNA and the cells were evaluated for changes in morphology, migration, invasion and adhesion. Actin cytoskeleton alterations were evaluated by fluorescent staining and levels of activated Rho GTPases by pull down assays. ECM1 downregulation led to significantly diminished cell migration (p = 0...

BACKGROUND: Young women exposed to a high hereditary breast and ovarian cancer (HBOC) risk are particularly vulnerable. They are ignored by health prevention measures but exposed to a stream of contradictory information (medicine, media, Internet). They may feel concerned about surgical prevention issues at a key moment of their identity construction (self, relationship, sexuality). We designed a special psychoeducational intervention to help these women cope better with these difficulties...

BACKGROUND Contrast enhanced spectral mammography (CESM) is a new method of breast cancer diagnosis in which an iodinated contrast agent is injected and dual-energy mammography is obtained in multiple views of the breasts. The aim of this study was to compare the degree of enhancement on CESM with lesion characteristics on mammography (MG) and lesion histology in women with suspicious breast lesions. MATERIAL AND METHODS The degree of enhancement on CESM (absent, weak, medium, or strong) was compared to lesion characteristics on MG (mass, mass with microcalcifications, or microcalcifications alone) and histology (infiltrating carcinoma, intraductal carcinoma, or benign) to compare sensitivity of the two modalities and to establish correlations that might improve diagnostic accuracy...

BACKGROUND: Although most triple-negative breast cancer (TNBC) patients initially respond to chemotherapy, residual tumor cells frequently persist and drive recurrent tumor growth. Previous studies from our laboratory and others' indicate that TNBC is heterogeneous, being composed of chemo-sensitive and chemo-resistant tumor cell subpopulations. In the current work, we studied the invasive behaviors of chemo-resistant TNBC, and sought to identify markers of invasion in chemo-residual TNBC...

In clinical routine pathology today, detection of protein in intact formalin-fixed, paraffin-embedded tissue is limited to immunohistochemistry, which is semi-quantitative. This study presents a new and reliable quantitative immunohistochemistry method, qIHC, based on a novel amplification system that enables quantification of protein directly in formalin-fixed, paraffin-embedded tissue by counting of dots. The qIHC technology can be combined with standard immunohistochemistry, and assessed using standard bright-field microscopy or image analysis...

Metastasis is one of the deadliest consequences of breast cancer, with bone being one of the primary sites of occurrence. Insufficient 3D biomimetic models currently exist to replicate this process in vitro. In this study, we developed a biomimetic bone matrix using 3D bioprinting technology to investigate the interaction between breast cancer (BrCa) cells and bone stromal cells (fetal osteoblasts and human bone marrow mesenchymal stem cells (MSCs)). A tabletop stereolithography 3D bioprinter was employed to fabricate a series of bone matrices consisting of osteoblasts/MSCs encapsulated in gelatin methacrylate (GelMA) hydrogel with nanocrystalline hydroxyapatite (nHA)...
