Emerging mechanisms of drug-induced phospholipidosis.

abstract：:One of the control mechanisms of cathepsin B biosynthesis and trafficking operates through alternative splicing of pre-mRNA. An mRNA lacking exon 2 is more efficiently translated than that containing all exons, and may be responsible for elevated biosynthesis and enzyme routing to the extracellular space, with critica...
