Following publication of the above article, the authors noticed an incorrect oligonucleotide sequence in the Materials and Methods section, under ‘Construction of AAV–Cck–shRNA and virus purification.’ In addition, the number of base pairs was incorrect. The sentence reading ‘For the Cck shRNA, a 15-base pair sequence in the coding region of the Cck gene (5′-CTTGAGCGGTTCGG-3′) was identified as a target region’ should have appeared as ‘For the Cck shRNA, a 24-base pair sequence in the coding region of the Cck gene (5′-GAACTCGCCAAGCCAGCTGATTTC-3′) was identified as a target region.’
