MetabolomicsFour layer multi-omics reveals molecular responses to aneuploidy in Leishmania

Aneuploidy causes system-wide disruptions in the stochiometric balances of transcripts, proteins, and metabolites, often resulting in detrimental effects for the organism. The protozoan parasite Leishmania has an unusually high tolerance for aneuploidy, but the molecular and functional consequenc...

MetabolomicsTranscriptional Shift and Metabolic Adaptations during Leishmania Quiescence Using Stationary Phase and Drug Pressure as Models

Microorganisms can adopt a quiescent physiological condition which acts as a survival strategy under unfavourable conditions. Quiescent cells are characterized by slow or non-proliferation and deep down-regulation of processes related to biosynthesis. Although quiescence has been described mostly...

MetabolomicsIntegrated genomic and metabolomic profiling of ISC1, an emerging Leishmania donovani population in the Indian subcontinent

Leishmania donovani is the responsible agent for visceral leishmaniasis (VL) in the Indian subcontinent (ISC). The disease is lethal without treatment and causes 0.2 to 0.4 million cases each year. Recently, reports of VL in Nepalese hilly districts have increased as well as VL cases cau...

TranscriptomicsMetabolic Reprogramming During Purine Stress in the Protozoan Pathogen Leishmania donovani
The ability of Leishmania to survive in their insect or mammalian host is dependent upon an ability to sense and adapt to changes in the microenvironment. However, little is known about the molecular mechanisms underlying the parasite response to environmental changes, such as nutrient availability....

MetabolomicsUntargeted metabolomics to understand the basis of phenotypic differences in amphotericin B-resistant Leishmania parasites

BACKGROUND: Protozoan Leishmania parasites are responsible for a range of clinical infections that represent a substantial challenge for global health. Amphotericin B (AmB) is increasingly used to treat Leishmania infection, so understanding the potential for resistance to this d...

TranscriptomicsBase J represses genes at the end of polycistronic gene clusters in Leishmania major by promoting RNAP II termination
Base J and H3.V promote RNA Polymerase (RNAP) II termination within polycistronic gene clusters in the kinetoplastid species Trypanosoma brucei. Although base J has been shown to promote RNAP II termination in the related kinetoplastid species Leishmania major and Leishmania tarentolae, the role of ...

MetabolomicsUntargeted LC-MS metabolomic studies of Asteraceae species to discover inhibitors of Leishmania major dihydroorotate dehydrogenase

INTRODUCTION: Interesting data about the family Asteraceae as a new source of Leishmania major dihydroorotate dehydrogenase (LmDHODH) inhibitors are presented. This key macromolecular target for parasites causing neglected diseases catalyzes the fourth reaction of the de novo pyr...

MetabolomicsAmphotericin B resistance in Leishmania mexicana: Alterations to sterol metabolism, lipid transport and oxidative stress response

Amphotericin B is increasingly used in treatment of leishmaniasis. Here, fourteen independent lines of Leishmania mexicana and one L. infantum line were selected for resistance to either amphotericin B or the related polyene antimicrobial, nystatin. Sterol profiling revealed tha...
