Combined transcriptome and proteome analysis of the protein composition of the brochosomes of the leafhopper Nephotettix cincticeps

ABSTRACT: Brochosomes are a unique coating on the integuments of Cicadellidae produced in specialized glandular sections of Malpighian tubules. However, knowledge of the protein composition of brochosome is very limited. In this study, transcriptomic and proteomic profiling was performed to characterize the protein composition of the brochosome in rice green leafhopper Nephotettix cincticeps. Brochosomes were collected from the forewings of leafhoppers using ultrasonic treatment allowing for more effective brochosome collection and shock treatment resulting in purer brochosomes . After combined proteomic and transcriptomic analysis, 12 putative major structural proteins of the brochosome (BSM) and 10 brochosome-associated proteins (BSAP) were identified. Each BSM has specific conserved motifs containing several cysteines cross-linked by disulfide bonds. BSAP, which may be loosely linked to the outer and inner surfaces of the brochosomes, might play an important role in the proper folding of the BSM and resisting pathogens. Apart from a few BSAPs associated with cyclase, homologs of BSM and BSAP were present exclusively in the insect family Cicadellidae rather than other Hemiptera species, suggesting that these proteins might be encoded by an orphan gene family specific to the Cicadellidae. This is the first study to identify and characterize the protein composition of the brochosome of N. cincticeps, which will provide a solid foundation for further studies of brochosome synthesis, function, and evolutionary origins.

Project description:The model describing that aberrant CpG island (CGI) methylation leads to transcription repression of tumor suppressor genes and thereby is implicated in tumor progression has been established in many cancers. However, recent studies indicated aberrantly hypermethylated genes in multiple cancers are already repressed in pre-cancerous tissues despite their promoters are hypomethylated. Here, we hypothesized that the occurrence of CGI promoter hypermethylation in cancers are associated with Polycomb-repressive complex and the associated H3K27me3 mark in pre-cancerous tissues. By using a ChIP-BS-seq technology that examines methylation of the DNA fragments precipitated by the antibodies to histone modifications, we provided direct evidences showing that genes highly enriched with H3K27me3 marks both in cancer and normal cells became aberrantly hypermethylated in CGI promoters in cancer cells in comparison with normal cells. Furthermore, we confirmed that these genes consistently were significantly hypermethylated in TCGA primary cancer in comparison with normal tissues. Thus, we provided direct evidences supporting that the presence of H3K27m3 may serve as a guide to promoter hypermethylation. This will spur future work on epigenetic signature of combined histone and DNA methylation that could define a cancerM-bM-^@M-^Ys epigenetic abnormalities, therefore helping distinguish subtypes of cancers and aiding future diagnosis and therapeutics of cancers. We applied ChIP-BS technology to examine H3K27me3 marks, which are catalyzed by the SET domain histone methyltransferase EZH2 and have a repressive function with 50bp pair-end sequencing. found H3K27me3 marks were enriched preferentially at CpG islands, (+/-500) transcription start sites (TSSs) and exons in two GC cell lines (BGC-823 and AGS). In YH cells, H3K27me3 marks were only preferentially enriched at CpG islands. In contrast, Hela cells presented a reverse pattern with highest H3K27me3 enrichment in intergenic regions. To confirm this result in Hela cells, we performed two independent replicates of ChIP-Seq and ChIP-BS-seq. Cause of useful was relative small. we still sequenced one 100bp pe reads replicate for H3K4me3 and two replicate for H3K27me3 ChIP-BS-seq.
