Figure 1From: High-throughput DNA analysis shows the importance of methylation in the control of immune inflammatory gene transcription in chronic periodontitisComparison of the variation in the methylation of probes in the region between +2,000 and ā2,000. Probes related to the immune-inflammatory genes (nā=ā5422), cell cycle (nā=ā4538), and stably expressed genes (nā=ā2349). Note that the frequency of probes with decreased methylation in periodontitis was higher in genes related to the immune system process (chi-squared test, pā<ā2.2eāāā16).Back to article page
