beta-Catenin is essential for E-cadherin-mediated cell adhesion in epithelial cells, but it also forms nuclear complexes with high mobility group transcription factors. Using a mouse mammary epithelial cell system, we have shown previously that conversion of epithelial cells to a fibroblastoid phenotype (epithelial-mesenchymal transition) involves(More)
The immune system undergoes profound age-related changes, including a gradual increase in the production and circulation of proinflammatory cytokines. Despite the known capacity of fibroblasts to produce cytokines, little is known so far about the inflammatory response of fibroblasts to cellular stress such as viral and/or bacterial infection in the context(More)
As a chronic antigenic stressor human Cytomegalovirus (CMV) contributes substantially to age-related alterations of the immune system. Even though monocytes have the greatest propensity for CMV-infection and seem to be an important host for the virus during latency, fibroblasts are also discussed to be target cells of CMV in vivo. However, little is known(More)
The cytochalasins stimulate steroid secretion of Y-1 adrenal tumor cells two-to threefold. The order of potencies is cytochalasin E is greater than D is greater than B, but the maximum response is the the same and always less than with ACTH. Like that with ACTH, the stimulation has a rapid onset, is easily reversible, is inhibited by cucloheximide and(More)
