Telomeres are a nucleoprotein structure at the end of the chromosome and are essential for genome integrity and chromosome stability. Telomere lengths are primarily maintained by a telomerase-mediated pathway but can be maintained by a homologous recombination-mediated pathway. However, detailed mechanisms of telomere maintenance are still unclear in many eukaryotes, including an important human pathogen, Trypanosoma brucei. Telomeres can be elongated by telomerase in T. brucei, a causative agent of fatal sleeping sickness in humans and nagana in cattle. T. brucei evades host immune response by regularly switching its major surface antigen, variant surface glycoprotein (VSG), a process known as …

Gliomas express mutant isocitrate dehydrogenases producing excessive amounts of D 2-hydroxyglutarate (D2HG) and releasing some of it into the environment. The immune surveillance is reduced as a result, however, the mechanisms behind lymphocyte suppression by the D2HG stereoisomer remain unknown. I incubated Jurkat T cells with D2HG at concentrations present within and surrounding gliomas, or its obverse L2HG stereoisomer, and quantified 2HG isomers within washed cells by TSPC derivatization with stable isotope-labeled D2HG and L2HG internal standards, HPLC separation, and mass spectrometry. D2HG was found in quiescent cells in double the amount of L2HG. External D2HG or L2HG increased the …

Ribosomal protein L13a plays an extra-ribosomal function in translational silencing of GAIT (IFN-gamma-activated inhibitor of translation) element bearing mRNAs encoding inflammatory proteins but the underlying molecular mechanism of translational silencing and ribosomal incorporation of L13a remains poorly understood. Also, our laboratory showed that L13a acts as a physiological defense against uncontrolled inflammation in macrophage-specific knockout (KO) mice. However, the consequence of a total knockout of L13a in mammals remains unexplored. Therefore, our current study is focused on (i) identifying the amino acid residue(s) of L13a essential for incorporation and translational silencing of target mRNAs and (ii) studying the consequences of …
