UNLABELLED Oxidative/nitrosative stress and mitochondrial dysfunction have been implicated in the degeneration of dopaminergic neurons in the substantia nigra during Parkinson's disease (PD). During early stages of PD, there is a significant depletion of the thiol antioxidant glutathione (GSH), which may lead to oxidative stress, mitochondrial dysfunction,… (More)

We report the whole genome sequences of a Mycobacterium smegmatis laboratory wild-type strain (MC(2) 155) and mutants (4XR1, 4XR2) resistant to isoniazid. Compared to Mycobacterium smegmatis MC(2) 155 (NC_008596), a widely used strain in laboratory experiments, the MC(2) 155, 4XR1, and 4XR2 strains are 60, 128 and 93 bp longer, respectively.
Many studies on M. tuberculosis have emerged from using M. smegmatis MC 2 155 (Msm), since they share significant similarities and yet Msm is non-pathogenic and faster growing. Although several individual molecules have been studied from Msm, many questions remain open about its metabolism as a whole and its capability to be versatile. Adaptability and… (More)
The biosynthesis of NAD constitutes an important metabolic module in the cell, since NAD is an essential cofactor involved in several metabolic reactions. NAD concentrations are known to be significantly increased in several cancers, particularly in glioma, consistent with the observation of up-regulation of several enzymes of the network. Modulating NAD… (More)
The global variations in the gene expression pattern of drug treated (½X) and laboratory evolved drug-resistant strains (2XR and 4XR) of Mycobacterium smegmatis were obtained and compared with the M. smegmatis mc(2) 155 (WT) strain. The genes exhibiting two-fold change and p-value <0.05 under the treated conditions have been considered as differentially… (More)
