ABSTRACT
<p><b>OBJECTIVE</b>To study differential expression profiles of ribosomal protein (RP) genes in healthy subjects and ulcerative colitis (UC) patients of Pi-asthenic syndrome (PAS) and of dampness-heat syndrome (DHS), thus providing experimental bases for " Pi as the source of qi and blood" theory from the view of protein synthesis.</p><p><b>METHODS</b>RP genes arrays were made. The mucous membrane of colon was detected in four UC patients of PAS (UC-PAS), four UC patients of DHS (UC-DHS), and four healthy subjects (N), and data analyzed using BRB-TOOL Software Package (3.9). Bioinformatics analyses were conducted in differential genes.</p><p><b>RESULTS</b>Low-density RP gene chips were successfully produced, including 77 RP genes and two RP like genes (RPL26-like1 and RPL7-like1). There were twelve differential genes between UC (PAS+DHS) and N, all of which were down-regulated genes. There were nineteen differential genes between UC-DHS and N, all of which showed down-regulating tendency. There were three differential genes between UC-PAS and N, all of which were down-regulated genes. There were six differential genes between UC-PAS and UC-DHS, all of which were up-regulated genes. Cluster analysis showed that normal and UC samples of this chip can be classified according to gene expression profiles, and UC-PAS and UC-DHS can be classified by clustering. Various differential genes had a common transcription regulatory factor.</p><p><b>CONCLUSIONS</b>RP genes arrays were successfully produced. RP gene expressions were down-regulated in UC-PAS and UC-DHS. Corresponding gene expression profiles were shown in N, UC-PAS and UC-DHS.</p>
