While most miRNA knockouts exhibit only subtle defects , a handful of miRNAs are profoundly required for development or physiology . A particularly compelling locus is Drosophila mir-279 , which was reported as essential to restrict the emergence of CO2-sensing neurons , to maintain circadian rhythm , and to regulate o...
Amongst the small number of miRNA knockouts that exhibit substantially overt phenotypes , mutants of Drosophila mir-279 are notable . Previous studies have uncovered its essential requirements in a range of developmental and behavioral assays . Surprisingly , we find that the phenotypes attributed to mir-279 deletions ...

Multiple In Vivo Biological Processes Are Mediated by Functionally Redundant Activities of Drosophila mir-279 and mir-996
Bacterial resistance to β-lactams may rely on acquired β-lactamases encoded by class 1 integron-borne genes . Rearrangement of integron cassette arrays is mediated by the integrase IntI1 . It has been previously established that integrase expression can be activated by the SOS response in vitro , leading to speculation...
The bacterial SOS response is a conserved regulatory network that is induced in response to DNA damage . Its activation in vitro leads to the emergence of resistance to antibiotics , leading to speculation that this is an important clinical mechanism of acquiring resistance . We found evidence here that antibiotic-indu...

Evidence for Induction of Integron-Based Antibiotic Resistance by the SOS Response in a Clinical Setting
Bacterial pathogens and their toxins target host receptors , leading to aberrant behavior or host death by changing signaling events through subversion of host intracellular cAMP level . This is an efficient and widespread mechanism of microbial pathogenesis . Previous studies describe toxins that increase cAMP in host...
Interference with regulation of host signaling by pathogens can alter gene expression , leading to functional disarray in the host cells that causes abnormal division or death . Here , we propose a previously undescribed model for how bacterial toxins subvert host processes via interaction with GRK2 that influences cAM...

Genomic Hotspots for Adaptation: The Population Genetics of Müllerian Mimicry in the Heliconius melpomene Clade
Protein knots , mostly regarded as intriguing oddities , are gradually being recognized as significant structural motifs . Seven distinctly knotted folds have already been identified . It is by and large unclear how these exceptional structures actually fold , and only recently , experiments and simulations have begun ...
Knots are ubiquitous in many aspects of our life , but remain elusive in proteins . The multitude of protein structures archived in the Protein Data Bank can be grouped into several hundred patterns , but only a handful are folded into knots . Combing through the recently added structures we found several novel knotted...

Hybridization and gene flow between species appears to be common . Even though it is clear that hybridization is widespread across all surveyed taxonomic groups , the magnitude and consequences of introgression are still largely unknown . Thus it is crucial to develop the statistical machinery required to uncover which...
Understanding the extent to which species or diverged populations hybridize in nature is crucially important if we are to understand the speciation process . Accordingly numerous research groups have developed methodology for finding the genetic evidence of such introgression . In this report we develop a supervised ma...

Plague , caused by Yersinia pestis , was classified as a reemerging infectious disease by the World Health Organization . The five human pneumonic plague cases in Yulong County in 2005 gave rise to the discovery of a Yulong plague focus in Yunnan province , China . Thereafter , continuous wild rodent plague ( sylvatic ...
Plague is a type of zoonosis that is highly lethal to humans . The surveillance of animal hosts is critical for the prevention and control of plague . The Yulong plague focus is a newly discovered plague focus in China in recent years . The plague outbreak had attracted widespread attention because 5 people were infect...
