title: ReproArray(GTS): a cDNA microarray for identification of reproduction-related genes in the giant tiger shrimp Penaeus monodon and characterization of a novel nuclear autoantigenic sperm protein (NASP) gene.
abstract: Expressed sequence tags (ESTs) were established from various tissues of the giant tiger shrimp (Penaeus monodon). To simultaneously examine expression patterns of a large number of transcripts in ovaries and testes of P. monodon, a cDNA microarray (ReproArray(GTS)) containing 4992 features amplified from cDNAs of ovary (1920) and testis (3072) EST libraries was constructed and subjected to high-throughput gene expression analysis in four different stages of ovarian development (previtellogenesis, vitellogenesis, early cortical rod and late cortical rod stages). Several transcripts were found to be differentially expressed during P. monodon ovarian development. Among many important reproduction-related genes with differential expression from microarray data, nuclear autoantigenic sperm protein (NASP) was further characterized by RACE-PCR. The full-length cDNA of P. monodon NASP (PmNASP) was 2126 bp in length containing an open reading frame (ORF) of 1812 bp corresponding to a deduced protein of 603 amino acids with 5? and 3?UTRs of 93 and 202 bp (excluding the poly A tail), respectively. Higher PmNASP transcript levels at later stages of ovarian development was consistently confirmed by quantitative real-time PCR. This study indicated that ReproArray(GTS) is effective for high-throughput screening of genes that play important roles in ovarian development of P. monodon.
