Extensive OMICS resources for Sf21 and High Five cell lines

ABSTRACT: Insect derived cell-lines, from Spodoptera frugiperda (Sf21) and from Trichoplusia ni (High Five), are ones of the most widely used systems for recombinant protein expression in Baculoviral Expression Vector System (BEVS). Genomic sequences and annotations are still incomplete for Sf21 or absent for High Five. In this study we present an approach using different sequencing data types with short-read sequencing, long synthetic and Oxford Nanopore reads to build genomes at an unprecedented resolution. The Sf21 and High Five assemblies contain 4,020 scaffolds of size, 463 Mb with N50 of 364 Kb and 2,954 scaffolds of size, 332 Mb with N50 of 326 Kb, respectively. Furthermore, we build a new gene prediction workflow, which integrates transcriptome proteome information using pre-existing tools. Using this approach, we could predict 21,506 Sf21 genes and 14,159 High Five genes, which were then functionally annotated. Finally, we also generate and integrate proteomic datasets to validate predicted genes. This integrative approach could be theoretically applied to any uncharacterized genome and result in valuable new resources. With this information available, Sf21 and High Five cells will become even better tools for protein expression and could be used in a wider range of applications, from promoter identifications to genome engineering and editing.

Project description:Specific Lactobacillus strains are marketed as probiotics i.e. health promoting organisms. As previously shown in vivo, L. plantarum WCFS1 modulates immune responses via nuclear factor (NF)kB in a growth phase dependent manner, likely caused by changed microbial cell surface characteristics. Here, we identified the differential cell-surface proteome composition of L. plantarum WCFS1 cells derived from the mid-logarithmic and late stationary growth phase by surface trypsination of intact bacterial cells, followed by a combined 1D- and 2D-LC-MS shotgun proteomics strategy, and growth phase dependent transcriptome analysis. Overall, these analyses led to the identification of 31 surface proteins differentially present in the logarithmic and stationary phase, whereas additional 17 and 33 proteins appeared solely present in stationary and logarithmic phase of growth, respectively. From 75% of predicted surface related genes displaying relatively high expression levels, the corresponding proteins were detected, demonstrating a high correlation between transcriptome and proteome profiles. The impact of cell-surface peptide fractions on cellular host responses was evaluated using NFkB promoter activation assays in intestinal epithelial cells, revealing that only late stationary phase derived peptides are capable of attenuating flagellin and cell envelope induced NFkB activation. Overall our data mechanistically expand earlier observations that revealed growth-phase dependent immunomodulation by L. plantarum WCFS1, leading to a typical adjuvant- or tolerance-like response after exposure to stationary phase harvested bacterial cells. Sub-fractionation of the late stationary phase peptide fraction revealed a sub-set of strong attenuator peptides able to manipulate NFkB related pathways to hereby attenuate pro-inflammatory signaling. Samples were hybridizedin a loop design linking each timepoint to the next as well as the previous timepoint. Additional hybridizations were introduced linking each sample three timepoints forward and three timepoints back. All samples were hybridized unsing at least each of the two dyes once.
