MASP micro-specimen samples at different spatial locations

ABSTRACT: Quantitative protein mapping on whole-tissue levels provides important insights into the spatially-organized regulatory processes/networks related to diseases and therapy, but remains a tremendous challenge. We describe a micro-scaffold assisted spatial proteomics(MASP) method, based on precise tissue spatial-compartmentalization using a 3D-printed micro-scaffold, capable of mapping thousands of proteins across a whole-tissue slice with excellent quantitative quality. The mapping accuracy was validated and applied in mapping >5,000 cerebral proteins in mouse brain. Under stringent cutoffs, 5019 unique proteins were mapped(N=208 micro-specimens) and 4577 proteins were mapped in all regions.

Accurate, in-depth mapping of proteins on whole-tissue levels provides comprehensive insights into the spatially-organized regulatory processes/networks in tissues, but is challenging. Here we describe a micro-scaffold assisted spatial proteomics (MASP) strategy, based on spatially-resolved micro-compartmentalization of tissue using a 3D-printed micro-scaffold, capable of mapping thousands of proteins across a whole-tissue slice with excellent quantitative accuracy/precision. The pipeline includ ...[more]

Project description:The tergal gland is a structure exclusive of adult male cockroaches that produces substances attractive to the female and facilitates mating. It is formed de novo in tergites 7 and 8 during the transition from the last nymphal instar to the adult. Thus, the tergal gland can afford a suitable case study to investigate the molecular basis of a morphogenetic process occurring during metamorphosis. Using Blattella germanica as model, we constructed transcriptomes from male tergites 7-8 in non-metamorphosing specimens, and from the same tergites in metamorphosing specimens. We performed a de novo assembly all available transcriptomes to construct a reference transcriptome and we identified transcripts by homology. Finally we mapped all reads into the reference transcriptome in order to perform analysis of differentially expressed genes and a GO-enrichment test. A total of 5,622 contigs appeared to be overrepresented in the transcriptome of metamorphosing specimens with respect to those specimens that did not metamorphose. Among these genes, there were six GO-terms with a p-value lower than 0.05 and among them GO: 0003676 (“nucleic acid binding”) was especially interesting since it included transcription factors (TFs). Examination of TF-Pfam-motifs revealed that the transcriptome of metamorphosing specimens contains the highest diversity of these motifs, with 29 different types (seven of them exclusively expressed in this stage) compared with that of non-metamorphosing specimens, which contained 24 motif types. Transcriptome comparisons suggest that TFs are important drivers of the process of tergal gland formation during metamorphosis. We sequenced the mRNA from the tergites 7-8 (where the tergal gland appears in the male adult individuals) with Roche 454 GS Junior System, in 4 different developmental stages; in nymph 5 during the ecdysone peak when flat tergites are being produced; in nymph 6 day 1 when the adult program its being initiated; nymph 6 day 1 treated with Juvenil Hormone that inhibits the adult program; and in nymph 6 during the ecdysone peak when tergal gland its being formed. Different transcription factors were found to play a crucial role in TG morphogenesis.

Project description:Schizophrenia (SCZ) is a common, disabling mental illness with high heritability but complex, poorly understood genetic etiology. As the first phase of a genomic convergence analysis of SCZ, we generated 16.7 billion nucleotides of short read, shotgun sequences of cDNA from post-mortem cerebellar cortices of 14 patients and six matched controls. A rigorous analysis pipeline was developed for analysis of digital gene expression studies. Sequences aligned to approximately 33,200 transcripts in each sample, with average coverage of 450 reads per gene. Following adjustments for confounding clinical, sample and experimental sources of variation, 215 genes differed significantly in expression between cases and controls. Golgi apparatus, vesicular transport, membrane association, Zinc binding and regulation of transcription were over-represented among differentially expressed genes. Twenty three genes with altered expression and involvement in presynaptic vesicular transport, Golgi function and GABAergic neurotransmission define a unifying molecular hypothesis for dysfunction in cerebellar cortex in SCZ. Experiment Overall Design: 16.7 billion nucleotides of shotgun, full length cDNA sequence data were generated using Illumina Genome Analyzer platforms with sequencing-by-synthesis (SBS) chemistry from 20 mRNA samples (Lister et al., 2008; Morin et al., 2008)(Mortazvi et al., 2008). mRNA samples were isolated post-mortem from the lateral hemispheres of the cerebellar cortices of 14 patients with SCZ and 6 control individuals (Paz et al., 2006; Bullock et al., In Press)(Table 1). Unrelated subjects were chosen to facilitate sampling of genetic heterogeneity (Freimer and Sabatti, 2004; McClellan et al., 2007). Cases and controls were approximately matched for age (cases, 45.2 + 11.8 years; controls 41.3 + 9.2 years), sex (all male), race, post-mortem interval (cases, 12.2 + 5.0 hours; controls 17.7 + 3.3 hours), cause of death, autopsy brain pH (cases, 6.54 + 0.19; controls 6.46 + 0.10) and RNA integrity number (cases, 8.06 + 0.53; controls, 7.87 + 0.41) (Table 1). 12.5 – 38.7 million, high quality sequences of length 32 – 36 bp were generated per sample (Table 2). Sequences were aligned to the human genome and RefSeq transcript databases using the algorithm GMAP, which allowed < 2 (< 6%) mismatches (Wu and Watanabe, 2005). There was little intra-sample variability in the number of sequences aligned to each locus from run-to-run or instrument-to-instrument (Fig. 1A; all source coefficient of variation 3.4%). 43.5 + 6.7% of sequences aligned to a transcript and 69.4 + 9.6% to the genome, evidence that annotation of mRNA isoforms in Homo sapiens is incomplete (Birney et al., 2007) (Table 2). 91% of alignments were unique (Table 2). Reads aligning to more than one location contained repetitive, paralogous, polymorphic or low complexity sequences and primarily mapped to untranslated regions or highly polymorphic gene families, such as major histocompatibility genes (Sugarbaker et al., 2008). Unmapped sequences did not align to mitochondrial or 1879 viral genomes, offering negative evidence of chronic viral etiology for SCZ in these patients.
