Prostaglandin endoperoxide synthase 2, also referred to as cyclooxygenase 2 (COX-2), is a key enzyme in the conversion of arachidonic acid to prostaglandins and other eicosanoids. Rat intestinal epithelial (RIE) cells were permanently transfected with a COX-2 expression vector oriented in the sense (RIE-S) or antisense (RIE-AS) direction. The RIE-S cells expressed elevated COX-2 protein levels ...
To determine signaling pathways responsible for modulation of COX-2 expression in nontransformed and transformed epithelial cells, we studied a rat intestinal epithelial (RIE) cell line expressing constitutively active Ras and RhoA. Expression of COX-2 protein was higher in RIE-RhoA(63L) (four-fold) and RIE-Ras(12V) (seven-fold) cells than in parental cells. Prior work suggests that Ras hyperac...
Right-sided infective endocarditis (RIE) occurs predominantly in intravenous drug users in western countries, and it has a relatively good prognosis. Clinical features and prognosis of RIE occurring in non-drug users are not well known. We investigated the clinical findings of RIE in non-drug users. We retrospectively reviewed 345 cases diagnosed with IE. Cases with RIE or left-sided infective ...
Two members of the myocardin protein family, myocardin-related transcription factor (MRTF)-A and MRTF-B are co-activators of serum response factor (SRF). We recently reported that MRTF-A/B activates the transcription of several actin cytoskeletal/focal adhesion genes SRF dependently, thereby enhancing the formation of stress fibers and focal adhesions. Here, we showed that the levels of caldesm...
Carrier lifetime degradation of reactive ion etch-processed silicon samples are investigated. Two types of carrier recombination: reversible and irreversible degradations induced by reactive ion etching (RIE) are identified. Irreversible carrier recombination is due to surface damage created by the RIE process that propagates a few microns deep into the silicon substrate. Reversible carrier rec...
We recently have shown that activated Ras, but not Raf, causes transformation of intestinal (RIE-1, IEC-6) epithelial cells, whereas both activated Ras and Raf transform NIH 3T3 fibroblasts (Oldham, S. M., Clark, G. J., Gangarosa, L. M., Coffey, R. J., and Der, C. J. (1996) Proc. Natl. Acad. Sci. U. S. A. 93, 6924-6928). The observations that conditioned medium from Ras-, but not Raf-, transfec...
