| Outline of Final Research Achievements |
Mycobacterium tuberculosis is an intracellular pathogen, has a remarkably slow growth rate, and survives long periods of time in the host. We found that overexpression of thyX in BCG (pthyX) resulted in accelerating its growth rate. We analyzed the gene expression profiles in pthyX using RNAseq. Several genes in folate metabolism pathway were up-ragulated in pthyX. We concluded that tetrahydrofolate is the key molecule in the control of the growth rate of slow-growing mycobacteria.
