An investigation of causal relationships between prediabetes and vascular complications.

Prediabetes is a state of glycaemic dysregulation below the diagnostic threshold of type 2 diabetes (T2D). Globally, ~352 million people have prediabetes, of which 35-50% develop full-blown diabetes within five years. T2D and its complications are costly to treat, causing considerable morbidity and early mortality.

Deregulation of RNA polymerase III transcription in cervical epithelium in response to high-risk human papillomavirus.

RNA polymerase (pol) III transcription is a major determinant of biosynthetic capacity, providing essential products such as tRNA and 5S rRNA. It is controlled directly by the tumour suppressors RB and p53. High-risk types of human papillomavirus (HPV), such as HPV16, express the oncoproteins E6 and E7 that can inactivate p53 and RB, respectively.

Direct regulation of RNA polymerase III transcription by RB, p53 and c-Myc.

The synthesis of tRNA and 5S rRNA by RNA polymerase (pol) III is cell cycle regulated in higher organisms. Overexpression of pol III products is a general feature of transformed cells. These observations may be explained by the fact that a pol III-specific transcription factor, TFIIIB, is strongly regulated by the tumor suppressors RB and p53, as well as the proto-oncogene product c-Myc.
