Telomere stability and carcinogenesis: an off-again, on-again relationship.

Previous studies in mice have demonstrated antagonistic effects of telomerase loss on carcinogenesis. Telomere attrition can promote genome instability, thereby stimulating initiation of early-stage cancers, but can also inhibit tumorigenesis by promoting permanent cell growth arrest or death. Human cancers likely develop in cell lineages with low levels of telomerase, leading to telomere losse...

Sigma and RNA polymerase: an on-again, off-again relationship?

In bacteria, a fundamental level of gene regulation occurs by competitive association of promoter-specificity factors called sigmas with RNA polymerase (RNAP). This sigma cycle paradigm underpins much of our understanding of all transcriptional regulation. Here, we review recent challenges to the sigma cycle paradigm in the context of its essential features and of the structural basis of sigma ...
