Primary Sjogren's syndrome study

ABSTRACT: The objective of the study was to identify gene expression signatures in minor salivary glands (MSGs) from patients with primary Sjogren's syndrome (SS). METHODS: A 16K complementary DNA microarray was used to generate gene expression profiles in MSGs obtained from 10 patients with primary SS and 10 control subjects. The data were analyzed by 2 different strategies, one strict primary analysis and one subanalysis that allowed for inclusion of genes with no signal in more than 3 samples from each group. The results were validated by quantitative reverse transcriptase-polymerase chain reaction techniques. RESULTS: We found a distinct difference in gene expression levels in MSGs, enabling a simple class prediction method to correctly classify 19 of the 20 samples as either patient or control,
