During HTLV-1 gene expression, positive transcription elongation factor b (pTEFb) is recruited to the long terminal repeat by Tax. Usually, additional proteins and elongation factors, known as the super elongation complex (SEC) and acting together with pTEFb, are required for efficient transcriptional elongation. To decipher further Tax targets that play a(More)
The oncoprotein Tax of human T-cell leukemia virus type 1 (HTLV-1) is a potent transactivator of viral and cellular transcription. Here, we identified ELL2 as the sole transcription elongation factor to be specifically upregulated in HTLV-1-/Tax-transformed T-cells. Tax contributes to regulation of ELL2, since transient transfection of Tax increases ELL2(More)
Triticone A is one member of a family of novel compounds which are spirocyclic lactams produced by several plant pathogenic fungi including Drechslera tritici repentis on wheat. It undergoes racemization to form triticone B and when tested, the enantiomeric mixture causes chlorosis and necrosis on a wide range of plants. Fluorescein diacetate treated(More)
Monocytes enter sites of microbial or sterile inflammation as the first line of defense of the immune system and initiate pro-inflammatory effector mechanisms. We show that activation with bacterial lipopolysaccharide (LPS) induces them to undergo a metabolic shift toward aerobic glycolysis, similar to the Warburg effect observed in cancer cells.
