Transcription profiling of two human paediatric cancer cell lines to identify alternatively spliced variants of Ciz1

ABSTRACT: Ciz1 promotes initiation of mammalian DNA replication and is present within nuclear matrix associated DNA replication factories. Depletion of Ciz1 from normal and cancer cells restrains entry to S phase and inhibits cell proliferation. Several alternative splicing events with putative functional consequences have been identified and reported, but many more variants are predicted to exist based on publicly available mRNAs and expressed sequence tags. Here we report the development and validation of a custom exon and exon-junction microarray focused on the human Ciz1 gene, capable of reproducible detection of differential splice-variant expression. Using a pair of paediatric cancer cell lines and a pool of eight normal lines as reference, the array identified expected and novel Ciz1 splicing
