Stevia preferences in Wistar rats
Psicothema, 2016 The Stevia rebaudiana plant is likely to become a major source of high-potency sweetener for the growing natural-food market. S. rebaudiana is the source of a number of sweet diterpenoid glycosides, but the major sweet constituents are rebaudioside A and stevioside.

Telomeres and Viruses: Common Themes of Genome Maintenance
Frontiers in Oncology, 2012 Genome maintenance mechanisms actively suppress genetic instability associated with cancer and aging. Some viruses provoke genetic instability by subverting the host’s control of genome maintenance.

Structural and functional analysis of the human POT1-TPP1 telomeric complex
Nature Communications, 2017 POT1 and TTP1 are part of the shelterin complex that caps and stabilizes the ends of telomeres. Here the authors present a structural analysis of the human POT1-TTP1 complex, shedding light on how it assembles and how cancer-associated mutations impact ...

Spontaneous Cholangiofibrosis in a Wistar Rat [PDF]
Toxicologic Pathology, 2019 In a 2-year carcinogenicity study, we identified a spontaneous cholangiofibrosis in a control male Wistar rat. This lesion has long been considered as a compound-related change, with no spontaneous cases reported in the Wistar rat. In addition to routine hematoxylin and eosin stains evaluation, we applied Masson’s trichrome staining, Alcian blue ...

CTCF driven TERRA transcription facilitates completion of telomere DNA replication
Nature Communications, 2017 TERRA RNA is involved in maintaining stability during telomere repeat replication. Here the authors, by using CRISPR/Cas9, mutate CTCF-binding sites at start site of TERRA transcripts and find that subtelomeric CTCF facilitates telomeric DNA replication ...

Topoisomerase 1 cleavage complex enables pattern recognition and inflammation during senescence
Nature Communications, 2020 Here, the authors show that the topoisomerase 1-DNA covalent cleavage complex plays a critical role in mediating cytoplasmic chromatin fragments recognition by cyclic GMP-AMP synthase during senescence.

Auricular chondritis in Wistar rats [PDF]
Laboratory Animals, 1990 The macroscopic and microscopic features of auricular chondritis in Wistar rats are described. Histologic lesions are characterized by granulomatous inflammation, chondrolysis, and multinodular proliferative foci. The condition in Wistar rats is compared to auricular chondritis in other strains of rats.
