Alternative splicing in osteoclasts and Paget's disease of bone.

ABSTRACT:

Background

Mutations in the SQSTM1/p62 gene have been reported in Paget's disease of bone (PDB), but they are not sufficient to induce the pagetic osteoclast (OC) phenotype. We hypothesized that specific RNA isoforms of OC-related genes may contribute to the overactivity of pagetic OCs, along with other genetic predisposing factors.

Methods

Alternative splicing (AS) events were studied using a PCR-based screening strategy in OC cultures from 29 patients with PDB and 26 healthy donors (HD), all genotyped for the p62P392L mutation. Primer pairs targeting 5223 characterized AS events were used to analyze relative isoform ratios on pooled cDNA from samples of the four groups (PDB, PDBP392L, HD, HDP392L). Of the 1056 active AS events detected in the screening analysis, 192 were r
