Methods are provided for modulating the expression of genes involved in
lipid metabolism, useful in the treatment of conditions associated with
cardiovascular risk. Antisense oligonucleotides targeted to
apolipoprotein B reduce the level of apolipoprotein B mRNA, lower serum
cholesterol and shift liver gene expression profiles from those of an
obese animal towards those of a lean animal. Further provided are methods
for improving the cardiovascular risk of a subject through antisense
inhibition of apolipoprotein B. Also provided are methods for employing
antisense oligonucleotides targeted to apolipoprotein B to modulate a
cellular pathway or metabolic process.
