RNAi in budding yeast.
RNA interference (RNAi), a gene-silencing pathway triggered by double-stranded RNA, is conserved in diverse eukaryotic species but has been lost in the model budding yeast Saccharomyces cerevisiae. Here, we show that RNAi is present in other budding yeast species, including Saccharomyces castellii and Candida albicans. These species use noncanonical Dicer proteins to generate small interfering ...
متن کاملSplicing factors facilitate RNAi-directed silencing in fission yeast.
Heterochromatin formation at fission yeast centromeres is directed by RNA interference (RNAi). Noncoding transcripts derived from centromeric repeats are processed into small interfering RNAs (siRNAs) that direct the RNA-induced transcriptional silencing (RITS) effector complex to engage centromere transcripts, resulting in recruitment of the histone H3 lysine 9 methyltransferase Clr4, and henc...

A Dutch-supported foundation is 'exporting' private health insurance to Nigeria, selling a US$ 30 health-care package for US$ 3. Gary Humphreys reports.
متن کاملRNAi-directed assembly of heterochromatin in fission yeast.
Heterochromatin is an epigenetically heritable and conserved feature of eukaryotic chromosomes with important roles in chromosome segregation, genome stability, and gene regulation. The formation of heterochromatin involves an ordered array of chromatin changes, including histone deacetylation, histone H3-lysine 9 methylation, and recruitment of histone binding proteins such as Swi6/HP1. Recent...
متن کاملNeurobiological regret and rejoice functions for aversive outcomes
A decision maker may experience regret when a choice he makes results in a more adverse outcome than a different choice would have yielded. Analogously, he may experience rejoice when his choice resulted in better outcomes. We used fMRI to investigate the neural correlates of regret and rejoice where payoffs are in terms of a non-monetary medium. Incentives were created using painful outcomes i...
