Project description:The aim of the study was to compare and contrast cytokine production by CD4+ chimeric antigen receptor + T-cells and putative myeloid derived suppressor cell populations (CD11b+Gr-1 hi and lo) in the spleens of Balb/c mice which had received a transfer of CD19 specific second-generation CAR T-cells 56 days previously following cyclophosphamide pre-conditioning. Splenocytes from four individual mice were pooled, incubated with antibodies to CD4, CD34 (CAR), CD11b, Gr-1 and sorted using flow cytometric cell sorting for CD4+CD34+, Gr-1 and the negative cell fraction. Total RNA was isolated and samples loaded in duplicate in the array. Data was normalized to global expression levels.

Project description:Welan gum is mainly produced by Sphingomonas sp. ATCC 31555 and has broad applications in industry such as that in cement production. Both carbon and nitrogen sources are essential for welan production. However, how nitrogen sources affect the metabolism and gene transcription of welan remains elusive. Here, we used next-generation sequencing RNA-seq to analyze the transcriptome of Sphingomonas sp. ATCC 31555 in the presence of inorganic or organic nitrogen sources. Enriched gene expression and pathway analysis suggest that organic nitrogen sources significantly enhanced the expression of genes in central metabolic pathways of Sphingomonas sp. ATCC 31555 and those critical for welan synthesis compared to that observed using inorganic nitrogen sources. The present study improves our understanding of the molecular mechanism underlying the use of nitrogen in welan synthesis in Sphingomonas sp., as well as provides an important transcriptome resource for Sphingomonas sp. in relation to nitrogen sources.

Project description:Thiabendazole (TBZ), a benzimidazole used against postharvest fungal growth and as anthelmintic in livestock farming, is highly persistent in soil (DT50> 1-2 years) and therefore challenging concerning its environmental management. In our recent copious attempts to isolate organisms that degrade TBZ, at best, we ended up with a soil microbial enrichment capable of accelerated TBZ degradation. Here, we employed a multi-omic approach combined with DNA stable isotope probing (SIP) for elucidating the underlying system complexity. We obtained 18 high-quality metagenome-assembled genomes, with six being dominant and versatile concerning their putative xenobiotics degradation ability. SIP combined with microbiome analysis verified our previous results about the key role of a Sphingomonas strain in TBZ degradation. Next to this, metabolomics suggested minimal/no cross-feeding events, and Sphingomonas being the sole TBZ degrader. RNA sequencing and proteomics analysis of the consortium using TBZ or succinate as sole carbon sources showed the enhanced expression in Sphingomonas of a carbazole dioxygenase locus with putative role in the TBZ degradation. Gene expression networking analysis suggested the interaction of Sphingomonas with a Hydrogenophaga strain that possibly contributes to the overall cobalamin balance. Our study depicts the need for integrated omic approaches for understanding complex interactions frequently occurring in bioremediation.

Project description:Drought and salinity are most ubiquitous environmental factors that causing hyperosmotic threats to Sphingomonas and impairs their efficiency of performing environmental functions. However, bacteria have developed various responses and regulation systems to coping with these abiotic challenges. Among which post-transcriptional regulation plays vital roles in regulating gene expression and cellular homeostasis, as hyperosmotic stress conditions could lead to induction of specific small RNA (sRNA) that participates in stress response regulation. Here, we report a candidate functional sRNAs landscape of S. melonis which could help for comprehensive analyses of sRNA regulation in Sphingomonas species. WGCNA analysis revealed a 263 nt sRNA SNC251 which transcribed from its own promoter and shew the most dramatic correlation coefficient with hyperosmotic factors was characterized. An in vivo translation-reporter system constructed in this study revealed positive regulation and feedback mechanisms between the SNC251 and nicotine degradation genes. Deletion of snc251 affected multiple cellular processes and nicotine degradation capacity of S. melonis TY, while overexpression of SNC251 facilitated the biofilm formation capability of TY under hyperosmotic stress. Two genes of TonB system were further verified could be activated by SNC251, which also means SNC251 is a trans-acting small RNA. Briefly, this research reported a summary of sRNAs which participate in hyperosmotic stress response in S. melonis TY and revealed a novel sRNA SNC251 which is necessary for hyperosmotic stress response.
