Project description:The objective of this study was to identify genes that are differentially regulated in cultured sympathetic neurons during BMP-induced dendritic growth and to determine the temporal expression patterns of these genes. We determined that inhibiting transcription within the first 24 hours after adding exogenous BMP-7 blocks BMP-induced dendritic growth in cultured sympathetic neurons dissociated from the superior cervical ganglia of embryonic rat pups. Thus, we determined the transcriptional profiles of cultured sympathetic neurons at 6 and 24 hours after addition of BMP-7 to identify early and later transcriptional responses that may drive dendrite formation. We isolated total RNA from sympathetic neurons exposed to three different experimental conditions: (1) no BMP-7 treatment; (2) treatment with BMP-7 for 6 hours; and (3) treatment with BMP-7 for 24 hours. Total RNA was labeled and hybridized to Affymetrix Rat Genome U34A oligonucleotide microarrays. This experiment was independently repeated three times using cultures derived from three independent dissections, such that a total of nine arrays were used. The nine samples were processed over two batches and the batching was balanced across the treatment conditions. Image data was processed using Affymetrix GCOS software to generate numeric, probe level data (CEL) and CEL data was then pre-processed using the RMA algorithm implemented by Partek Genomics Suite (St. Louis, MO). Following batch correction of the probe set level, normalized data using Partek, differential gene expression was determined by two-way ANOVA and linear contrasts between all treatment conditions were applied to generate fold-change values along with the statistical p-value. Lists of significantly changed transcripts were uploaded to MetaCore (GeneGo, ) for mining biological annotation and network analysis.

Project description:Few studies have assessed the patterns of parasite populations of rodents over a longitudinal gradient in Chile. In this work, the gastrointestinal helminthic fauna of invasive rodents in Chile was examined to assess the association between their presence/absence and abundance with latitude, host sex, and host body condition, and to assess the coexistence and correlation of the abundance between parasite species. Rodents were obtained from 20 localities between 33 and 43°S. Helminths were extracted from the gastrointestinal tract and identified morphologically. Overall, 13 helminth taxa were obtained. The most frequently identified parasite species was Heterakis spumosa, and the most abundant was Syphacia muris, while Physaloptera sp. was the most widely distributed. No locality presented with a coexistence that was different from that expected by chance, while the abundance of five helminthic species correlated with the abundance of another in at least one locality, most likely due to co-infection rather than interaction. Host sex was associated with parasite presence or abundance, and female sex-biased parasitism was notably observed in all cases. Body condition and latitude presented either a positive or negative association with the presence or abundance of parasites depending on the species. It is notable that the likely native Physaloptera sp. is widely distributed among invasive rodents. Further, gravid females were found, suggesting spillback of this species to the native fauna. The low frequency and abundance of highly zoonotic hymenolepid species suggest that rodents are of low concern regarding gastrointestinal zoonotic helminths.
