Western blotting of the insulin-secreting beta-cell lines HIT-15 and RINm5F with anti-SNAP-25 (synaptosomal associated protein of 25 kDa), anti-synaptobrevin, and anti-syntaxin 1 antibodies revealed the presence of proteins with the same electrophoretic mobility as found in neural tissue. Permeabilization of both of these insulinoma cell lines to botulinum neurotoxin A by electroporation resulted, after 3 days of culture, in the loss of approximately 90% of SNAP-25 immunoreactivity. A similar… CONTINUE READING
