In an asthma attack, smooth muscle cells constrict thereby narrowing small airway and making it
difficult to move air in and out of the lungs. Your biotech firm has developed a new technique for
selectively altering gene expression in the smooth muscle of airways. How would you re-engineer these cells to cure
asthma?
A. Inhibit
expression of adenylate cyclase
B. Inhibit expression of myosin light chain
kinase
C. Overexpress acetylcholine receptors
D. Overexpress sacrcolemmal calcium channels
