Fetomodulin (FM) was previously shown to be a surface marker protein of parietal endoderm by in vitro differentiation of F9 embryonal carcinoma cells and by immunohistochemistry of in vivo embryos. BALB/3T3 and sarcoma S180 cells of the mouse were also shown to possess a protein which was indistinguishable from FM by immunological and structural criteria.(More)
The region preceding the beta-lactamase promoter of Escherichia coli plasmid pUC19 has a curved DNA (bent DNA) structure. The center of the curvature was revealed to exist around nucleotide position 2580 of the plasmid, which is just beside RNA polymerase binding region. It was indicated that the identified region is curved even at 60 degrees C. The gross(More)
The role of the bent DNA within human adenovirus type 2 (Ad2) enhancer in transcriptional activation of E1A gene has been investigated. The bent region of the enhancer was substituted by a straight DNA fragment or by a bent DNA fragment of 194 bp from origin region of phage lambda replication. Employing an in vitro transcription system using HeLa cell(More)
The cysteine protease caspase-8 plays an essential role in apoptosis induced by death receptors. The protein synthesis inhibitor acetoxycycloheximide (Ac-CHX) has been previously shown to induce rapid apoptosis mediated by the release of cytochrome c in human leukemia Jurkat cells. In this study, the novel molecular mechanism that links caspase-8 to the(More)
We propose a conformational nomenclature for amphiphilic lipid molecules that is general and compatible with the stereospecific numbering scheme, in contrast to earlier methods in which discrepancies with the sn-scheme lead to contradictory assignments of the absolute configuration of the system. The present method can be rationally extended to different(More)
Two-point boundary-value problems are investigated by the method of barriers for ordinary differential equations of the second and the third order. 1. In studying boundary-value problems for ordinary differential equations one often comes across situations where the most popular methods of obtaining a priori estimates including the maximum principle, the(More)
