Downregulation of carcinoembryonic antigen-related cell adhesion molecule (CEACAM1), a cell adhesion molecule with tumor suppressing properties has been observed in a high percentage of carcinomas of the endometrium and other malignancies. The mechanisms for the dysregulation and the role of hormones and cytokines on the expression of CEACAM1 in endometrial carcinomas is unknown. We therefore s...
α-Tectorin (TECTA), β-tectorin (TECTB), and carcinoembryonic antigen-related cell adhesion molecule 16 (CEACAM) are secreted glycoproteins that are present in the tectorial membrane (TM), an extracellular structure overlying the hearing organ of the inner ear, the organ of Corti. Previous studies have shown that TECTA and TECTB are both required for formation of the striated-sheet matrix within...
The differentiation of colorectal cancer cells is associated with the arrest of tumor growth and tumor regression. However, the mechanism of such tumor cell differentiation has not yet been elucidated. Several adenocarcinoma cell lines, including HT29 which differentiates only upon stimulation with a differentiation agent, have been used for the study of colorectal cells. Since we had previousl...
The carcinoembryonic antigen-related cell adhesion molecule 1 regulates insulin sensitivity by promoting hepatic insulin clearance. Mice bearing a null mutation of Ceacam1 gene (Cc1(-/-)) develop impaired insulin clearance followed by hyperinsulinemia and insulin resistance, in addition to visceral obesity and increased plasma fatty acids. Because insulin resistance is associated with increased...
Although the specific functions of sleep have not been completely elucidated, the literature has suggested that sleep is essential for proper homeostasis. Sleep loss is associated with changes in behavioral, neurochemical, cellular, and metabolic function as well as impaired immune response. Using high-resolution microarrays we evaluated the gene expression profiles of healthy male volunteers w...
A common overlapping site on the N-terminal IgV-like domain of human carcinoembryonic antigen (CEA)-related cell adhesion molecules (CEACAMs) is targeted by several important human respiratory pathogens. These include Neisseria meningitidis (Nm) and Haemophilus influenzae (Hi) that can cause disseminated or persistent localized infections. To define the precise structural features that determin...
Carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) is expressed in the epithelium of various primate tissues, including lung airway and alveoli. In human lung, CEACAM6 is developmentally and hormonally regulated, protects surfactant function, has anti-apoptotic activity and is dysregulated in cancers. We hypothesized that alveolar CEACAM6 expression increases in lung injury and...
BACKGROUND Colorectal cancer (CRC) represents a morphologic and molecular heterogenic disease. This heterogeneity substantially impairs drug effectiveness and prognosis. The subtype of mismatch repair deficient (MMR-D) CRCs, accounting for about 15% of all cases, shows particular differential responses up to resistance towards currently approved cytostatic drugs. Pre-clinical in vitro models re...
Circulating monocytes in the bloodstream typically migrate to other tissues and differentiate into tissue resident macrophages, the process being determined by the constituents of the microenvironments encountered. These may include microbes and their products. In this study, we investigated whether Moraxella catarrhalis Ubiquitous Surface Protein A1 (UspA1), known to bind to a widely expressed...
