Abstract:
The whole-genome sequence analysis of Mycobacterium leprae, which was completed in 2001, revealed the characteristics of this microbe's genomic structure. Half of the M. leprae genome consists of a limited number of protein-coding genes and the rest comprises non-coding regions and pseudogenes. We performed membrane array and tiling array analyses to analyze the gene-expression profile of the M. leprae genome and found that pseudogenes and non-coding regions were expressed similarly to coding regions at the RNA level. The RNA expressions were confirmed by real-time PCR analysis. Expression of these RNAs in clinical samples showed varying patterns among patients, thus indicating that the analysis of RNA expression patterns, including non-coding regions and pseudogenes, may be useful for understanding the pathological state, prognosis, and assessment of therapeutic progress in leprosy.
