GNAQ and GNA11 are heterotrimeric G protein alpha subunits, which are mutated in a mutually exclusive pattern in most cases of uveal melanoma, one of the most aggressive cancers. Here we introduce the first transgenic mouse model of uveal melanoma
In this study, the impacts of three preoxidation strategies [i.e., using potassium permanganate (KMnO(4)), chlorine dioxide (ClO(2)), or hydrogen peroxide (H(2)O(2))] before preformed monochloramine (NH(2)Cl) addition on the formation and speciation of iodinated trihalomethanes (I-THMs) were evaluated at the Br(-)/I(-)

Open complex formation precedes initiation of transcription by RNA polymerases. In the analysis of transcription initiation from eukaryotic class II promoters, we have used promoter DNA structures that represent intermediates in open complex formation. We describe the preparation and isolation
Repressor activator protein 1 (Rap1) is an essential factor involved in transcription and telomere stability in the budding yeast Saccharomyces cerevisiae. Its interaction with DNA causes hypersensitivity to potassium permanganate, suggesting local DNA melting and/or distortion. In this study, various
Indolosesquiterpenoids are a growing class of natural products that exhibit a wide range of biological activities. Here, we report the total syntheses of xiamycin A and oridamycins A and B, indolosesquiterpenoids isolated from Streptomyces. Two parallel strategies were exploited to
