Regulation Of Alpha- And Beta-Actin Isoforms In The Contracting A7r5 Smooth Muscle Cell, Dawn Leah Brown-Turner
Regulation Of Alpha- And Beta-Actin Isoforms In The Contracting A7r5 Smooth Muscle Cell, Dawn Leah Brown-Turner
Theses, Dissertations and Capstones
Two isoforms of actin have been found to be present in A7r5 smooth muscle cells, α- and β-actin. This body of work sets out to examine the different regulatory factors of the two actin isoforms during smooth muscle contraction. The response of the actin isoforms to phorbol 12, 13-dibutyrate (PDBu) is markedly different. α-Actin remodels to podosomes around the periphery of the cell, while β-actin merely shortens. One protein involved in smooth muscle contraction induced by PDBu is protein kinase C (PKC). Two inhibitors of PKC, staurosporine and bisindolymaleimide, were used prior to PDBu stimulation and after PDBu stimulation to …

The synthesis and characterization of some substituted benzyl N-nitrosocarbamates with an N-2-(methylthio)ethyl or a bis(2-aminoethyl)sulfide functionality is reported, as a part of a long-term goal to design and prepare novel photolabile structures that could be used as substances for controlled release of alkylating and/or crosslinking agents. The synthesis was accomplished by reaction of benzyl chloroformates with the corresponding amines, resulting in the preparation of carbamates. The latter were subsequently nitrosated, utilizing two different N-nitrosation methods, to yield the target structures.
