Future curative cancer chemotherapies have to overcome tumor cell heterogeneity and plasticity. To test the hypothesis that the tumor suppressor maspin may reduce microenvironment-dependent prostate tumor cell plasticity and thereby modulate drug sensitivity, we established a new schematic combination of twodimensional (2D), three-dimensional (3D), and suspension cultures to enrich prostate can...
Maspin, a member of the serine protease inhibitor (serpin) family, is a tumor suppressor in breast and prostate cancer. To address molecular mechanisms underlying maspin's activity, we restored its expression in invasive carcinoma cells and analyzed the resulting changes by shotgun proteomics. Using a mass spectrometry-based multidimensional proteomic method, we observed changes to the expressi...
AIMS Maspin, a 42-kDa serine proteinase inhibitor, is a tumor suppressor protein that stimulates apoptosis and inhibits motility, invasion and cancer metastasis. Mutant maspin leads to partial loss of tumor suppressor function, decreased susceptibility to apoptosis and to malignant progression. We recently found maspin expression (ME) in the cytoplasm of serrated colonic lesions, such as hyperp...
Metaplastic carcinomas of the breast (MCBs) are unusual neoplasms characterized by an admixture of glandular epithelial components, which frequently exhibit features of squamous differentiation, and mesenchymal malignant components. Regardless of the presence of myoepithelial features in MCB, no consensus concerning their putative histogenesis has yet been achieved. Recently, novel putative myo...
Transcription factor ATF-2 is a nuclear target of stress-activated protein kinases, such as p38, which are activated by various extracellular stresses, including UV light. Here, we show that ATF-2 plays a critical role in hypoxia- and high-cell-density-induced apoptosis and the development of mammary tumors. Compared to wild-type cells, Atf-2(-/-) mouse embryonic fibroblasts (MEFs) were more re...
Oral squamous cell carcinoma (OSCC) is a common malignancy with a growing worldwide incidence and prevalence. The N-myc downstream regulated gene (NDRG) family of NDRG1, 2, 3, and mammary serine protease inhibitor (Maspin) gene are well-known modulators in the neoplasia process. Current research has considered iron chelators as new anti-cancer agents; however, the anticancer activities of iron ...
Background. The aim of this study was to investigate maspin and ezrin expression in different subtypes of periocular basal cell carcinoma (BCC). Methods. Tissue samples from 43 patients with periocular BCC. Our cases were comprised of 10 morpheaform, 25 nodular, and 8 adenoid type BCCs. Immunohistochemical staining for maspin and ezrin was performed by Envision detection system. Results. There ...

BACKGROUND Maspin, a member of the serpin family of protease inhibitors, is known to be a tumor suppressor. Although the relationship between its expression and biological significance has been investigated in several types of cancer, the clinicopathological significance of maspin expression in colorectal cancer has not been fully elucidated. MATERIALS AND METHODS The expression of maspin in ...
