Dual role of allele-specific DNA hypermethylation within the TERT promoter in c...
Lee, Donghyun D.; Komosa, Martin; Sudhaman, Sumedha; Leão, Ricardo; Zhang, Cindy H.; Apolonio, Joana D.; Hermanns, Thomas; Wild, Peter J.Aberrant activation of telomerase in human cancer is achieved by various alterations within the TERT promoter, including cancer-specific DNA hypermethylation of the TERT hypermethylated oncological region (THOR). However, the impact of allele-specific DNA methylation within the TERT promoter on gene transcription remains incompletely understood. Using allele-specific next-generation sequencing, we screened a la...
Combined genetic and epigenetic alterations of the TERT promoter affect clinica...
Leão, Ricardo; Lee, Donghyun; Figueiredo, Arnaldo; Hermanns, Thomas; Wild, Peter; Komosa, Martin; Lau, Irene; Mistry, Mathew; Nunes, Nuno MiguelIn urothelial bladder cancer (UBC), risk stratification remains an important unmet need. Limitless self-renewal, governed by TERT expression and telomerase activation, is crucial for cancer progression. Thus, telomerase activation through the interplay of mutations (TERTpMut ) and epigenetic alterations in the TERT promoter may provide further insight into UBC behavior. Here, we investigated the combined effect...
The Toxoplasma gondii rhoptry protein ROP18 is an Irga6-specific kinase and reg...
Hermanns, Thomas; Müller, Urs B; Könen-Waisman, Stephanie; Howard, Jonathan C; Steinfeldt, TobiasIn mice, avirulent strains (e.g. types II and III) of the protozoan parasite Toxoplasma gondii are restricted by the immunity-related GTPase (IRG) resistance system. Loading of IRG proteins onto the parasitophorous vacuolar membrane (PVM) is required for vacuolar rupture resulting in parasite clearance. In virulent strain (e.g. type I) infections, polymorphic effector proteins ROP5 and ROP18 cooperate to phosph...
