non cell autonomous upregulation of cdkn2 transcription linked to progression of chronic hepatitis c disease.chronic hepatitis c virus infection (c-hc) is associated with higher mortality arising from hepatic and extrahepatic disease. this may be due to accelerated biological aging; however, studies in c-hc have thus far been based solely on telomere length as a biomarker of aging (boa). in this study, we have evaluated cdkn2 locus transcripts as alternative boas in c-hc. our results suggest that c-hc induces non-cell-autonomous senescence and accelerates biological aging. the cdkn2 locus may provide a ...201323931242
burkholderia oklahomensis agglutinin is a canonical two-domain oaa-family lectin: structures, carbohydrate binding and anti-hiv activity.burkholderia oklahomensis eo147 agglutinin (boa) is a 29 kda member of the oscillatoria agardhii agglutinin (oaa) family of lectins. members of the oaa family recognize high-mannose glycans, and, by binding to the hiv envelope glycoprotein 120 (gp120), block the virus from binding to and entering the host cell, thereby inhibiting infection. oaa-family lectins comprise either one or two homologous domains, with a single domain possessing two glycan binding sites. we solved the structure of boa in ...201323480609
an abc pleiotropic drug resistance transporter of fusarium graminearum with a role in crown and root diseases of wheat.fgabc1 (fgsg_04580) is predicted to encode a pleiotropic drug resistance class abc transporter in fusarium graminearum, a globally important pathogen of wheat. deletion mutants of fgabc1 showed reduced virulence towards wheat in crown and root infection assays but were unaltered in infectivity on barley. expression of fgabc1 during head blight and crown rot disease increases during the necrotrophic phases of infection suggestive of a role for fgabc1 in late infection stages in different tissue t ...201323965171
predation of alouatta puruensis by boa constrictor.reports of successful predator attacks on primates are rare. primates from all major radiations are particularly susceptible to raptors, carnivores, and snakes. among new world primates, reports of snake predation are limited to medium- and small-bodied species. here, we report the first documented case of successful predation of an atelid by a snake-an adult female purús red howler monkey, alouatta puruensis, that was subdued by a ca. 2-m-long boa constrictor in an arboreal setting at a height ...201323917944
