Are constriction velocities of renal afferent and efferent arterioles of mice related to SMB expression?
Our results suggest that the presence of different alternatively 5'-spliced smooth muscle-myosin heavy chain (SM-MHC) isoforms does not dominate the different contractile features of physiologically loaded renal afferent or efferent arterioles.
Our observations suggest that the expression of a mutant SOD-1 gene, as occurs in familial ALS, does not compromise the trophic effects of GDNF on motoneuron survival, but may affect the development of motoneurons.
