Mice typically produce apolipoprotein B (apoB)-48 and not apoB100. Apolipoprotein B100 accumulates in Bruch's membrane prior to basal deposit and drusen formation during the onset of AMD, raising the possibility that they are a trigger for these Bruch's membrane alterations.

Oligonucleotides modified by clinically ineffective trans-diamminedichloridoplatinum(II) (transplatin) have been shown to be effective modulators of gene expression. This is so because in some nucleotide sequences the 1,3-GNG intrastrand adducts formed by transplatin in double-helical DNA readily rearrange into interstrand cross-links
