    • Early Evolutionary Selection of NAD Biosynthesis Pathway in Bacteria 

      Sharma, Suraj; Hsieh, Yin-Chen; Dietze, Jørn; Bockwoldt, Mathias; Strømland, Øyvind; Ziegler, Mathias; Heiland, Ines (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-21)
      Bacteria use two alternative pathways to synthesize nicotinamide adenine dinucleotide (NAD) from nicotinamide (Nam). A short, two-step route proceeds through nicotinamide mononucleotide (NMN) formation, whereas the other pathway, a four-step route, includes the deamidation of Nam and the reamidation of nicotinic acid adenine dinucleotide (NAAD) to NAD. In addition to having twice as many enzymatic ...

    • Hypoxia Inducible Factor 1α Inhibits the Expression of Immunosuppressive Tryptophan-2,3-Dioxygenase in Glioblastoma 

      Mohapatra, Soumya R.; Sadik, Ahmed; Tykocinski, Lars-Oliver; Dietze, Jørn; Poschet, Gernot; Heiland, Ines; Opitz, Christiane A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-04)
      Abnormal circulation in solid tumors results in hypoxia, which modulates both tumor intrinsic malignant properties as well as anti-tumor immune responses. Given the importance of hypoxia in glioblastoma (GBM) biology and particularly in shaping anti-tumor immunity, we analyzed which immunomodulatory genes are differentially regulated in response to hypoxia in GBM cells. Gene expression analyses ...
