Arguments

query

The search query. Either plain text ('traumatic'), or an ontology term URI ('http://purl.obolibrary.org/obo/UBERON_0002048'). Datasets that contain the given string in their short or full name will also be matched. Can be multiple identifiers separated by commas.

taxon

Can either be Taxon ID, Taxon NCBI ID, or one of its string identifiers: scientific name, common name. It is recommended to use Taxon ID for efficiency. Please note, that not all taxa have all the possible identifiers available. Use the get_taxa_by_ids function to retrieve the necessary information. For convenience, below is a list of officially supported taxa:

IDComm.nameScient.nameNcbiID
1humanHomo sapiens9606
2mouseMus musculus10090
3ratRattus norvegicus10116
11yeastSaccharomyces cerevisiae4932
12zebrafishDanio rerio7955
13flyDrosophila melanogaster7227
14wormCaenorhabditis elegans6239
offset

The offset of the first retrieved result.

limit

Optional, defaults to 20. Limits the result to specified amount of objects. Has a maximum value of 100. Use together with offset and the totalElements attribute in the output to compile all data if needed.

sort

Order results by the given property and direction. The '+' sign indicate ascending order whereas the '-' indicate descending.

raw

TRUE to receive results as-is from Gemma, or FALSE to enable parsing. Raw results usually contain additional fields and flags that are omitted in the parsed results.

memoised

Whether or not to save to cache for future calls with the same inputs and use the result saved in cache if a result is already saved. Doing options(gemma.memoised = TRUE) will ensure that the cache is always used. Use forget_gemma_memoised to clear the cache.

file

The name of a file to save the results to, or NULL to not write results to a file. If raw == TRUE, the output will be a JSON file. Otherwise, it will be a RDS file.

overwrite

Whether or not to overwrite if a file exists at the specified filename.

attributes

If TRUE additional information from the call will be added into the output object's attributes such as offset and available elements.

...

Kept for compatibility, ignored.

Value

A data table with information about the queried dataset(s). A list if raw = TRUE. Returns an empty list if no datasets matched.

The fields of the output data.table are:

  • experiment.shortName: Shortname given to the dataset within Gemma. Often corresponds to accession ID

  • experiment.name: Full title of the dataset

  • experiment.ID: Internal ID of the dataset.

  • experiment.description: Description of the dataset

  • experiment.troubled: Did an automatic process within gemma or a curator mark the dataset as "troubled"

  • experiment.accession: Accession ID of the dataset in the external database it was taken from

  • experiment.database: The name of the database where the dataset was taken from

  • experiment.URI: URI of the original database

  • experiment.sampleCount: Number of samples in the dataset

  • experiment.batchEffectText: A text field describing whether the dataset has batch effects

  • experiment.batchCorrected: Whether batch correction has been performed on the dataset.

  • experiment.batchConfound: 0 if batch info isn't available, -1 if batch counfoud is detected, 1 if batch information is available and no batch confound found

  • experiment.batchEffect: -1 if batch p value < 0.0001, 1 if batch p value > 0.1, 0 if otherwise and when there is no batch information is available or when the data is confounded with batches.

  • experiment.rawData: -1 if no raw data available, 1 if raw data was available. When available, Gemma reprocesses raw data to get expression values and batches

  • geeq.qScore: Data quality score given to the dataset by Gemma.

  • geeq.sScore: Suitability score given to the dataset by Gemma. Refers to factors like batches, platforms and other aspects of experimental design

  • taxon.name: Name of the species

  • taxon.scientific: Scientific name for the taxon

  • taxon.ID: Internal identifier given to the species by Gemma

  • taxon.NCBI: NCBI ID of the taxon

  • taxon.database.name: Underlying database used in Gemma for the taxon

  • taxon.database.ID: ID of the underyling database used in Gemma for the taxon

We examine the transcriptomic inflmmatory signature of generated astrocytes following Il1Beta exposure in BD vs. control Results: BD-patient astrocytes show a unique inflammatory response with differentially regulated genes.\nAt time of import, last updated (by provider) on: Mar 19 2021\n\nContributors: ; [Maxim N Shokhirev, Fred Gage, Krishna Vadodaria, Carol Marchetto]

Lithium is recommended as first-line treatment for the maintenance treatment of bipolar-affective disorder in current guidelines, its molecular modes of action are however poorly understood. Cell models derived from bipolar patients could prove useful to gain more insight in the molecular mechanisms of bipolar disorder and the common pharmacological treatments. As primary neuronal cell lines cannot be easily derived from patients, peripheral cell models should be evaluated in their usefulness to study pathomechanisms and the mode of action of medication as well as in regard to develop biomarkers for diagnosis and treatment response.\nAt time of import, last updated (by provider) on: Mar 25 2019\n\nContributors: ; [Sarah Kittel-Schneider, Max Hilscher, Andreas Reif, Claus J Scholz]

However, the therapeutic targetsof VPA have remained elusive. Here we  used RNA sequencing  in human  iPSCs derived from  bipolar  patients  to further identify important molecular targets. Human iPSCs were homogenized and total RNA was isolated using the RNeasy Plus Micro Kit (Qiagen, Hilden, Germany). RNA quantity and quality were assessed using fluorometry (Qubit RNA Broad Range Assay Kit and Fluorometer; Invitrogen, Carlsbad, CA) and chromatography (Bioanalyzer and RNA 6000 Nano Kit; Agilent, Santa Clara, CA), respectively. Libraries were prepared using TruSeq Stranded mRNA (PolyA+) kit (Illumina, San Diego, CA) and sequenced by Illumina NextSeq 500. The read length was 75bp with 30-40M reads per sample. FastQC (v0.11.3) was performed to assess data quality. TopHat2 (v2.0.9) aligned the reads to the mouse reference genome (Mus musculus UCSC mm10) and to the Ensembl human reference genome (GRCh38.p13) using default parameters. Alignments were then converted to expression count data using HTseq (v0.6.1) with default union mode.\nAt time of import, last updated (by provider) on: Dec 31 2020\n\nContributors: ; [George Tseng, Colleen McClung, Wei Zong, Ryan Logan]
#> 10: This experiment was created by Gemma splitting another: \nExpressionExperiment Id=20933 Name=TCF7L2 lncRNA: A Link between Bipolar Disorder and Body Mass Index through Glucocorticoid Signaling [RNA-Seq] (GSE179921) Bipolar disorder (BD) and obesity are highly comorbid. We previously performed a genome-wide association study (GWAS) for BD risk accounting for the  effect of body mass index (BMI) which identified a genome-wide significant single-nucleotide polymorphism (SNP) in the gene encoding the transcription factor 7 like 2 (TCF7L2). However, the molecular function of TCF7L2 in the central nervous system (CNS) and its possible role in BD and BMI interaction remained unclear. In the present study, we demonstrated by studying human induced pluripotent stem cell (hiPSC)-derived astrocytes, cells which highly express TCF7L2 in the CNS, that the BD-BMI GWAS risk SNP is associated with glucocorticoid-dependent repression of the expression of a previously uncharacterized TCF7L2 transcript variant. That transcript is a long non-coding RNA (lncRNA-TCF7L2) that is highly expressed in the CNS but not in peripheral tissues such as the liver and pancreas which are involved in metabolism.  In astrocytes, knock-down of the lncRNA-TCF7L2 resulted in decreased expression of the parent gene, TCF7L2, as well as alterations in the expression of a series of genes involved in insulin signaling and diabetes.  We also studied the function of TCF7L2 in hiPSC-derived astrocytes by integrating RNA sequencing data after TCF7L2 knock-down with TCF7L2 chromatin-immunoprecipitation sequencing (ChIP-seq) data. Those studies showed that TCF7L2 directly regulated a series of BD-risk genes. In summary, these results support the existence of a CNS-based mechanism underlying BD-BMI genetic risk, a mechanism based on a glucocorticoid-dependent expression quantitative trait locus that regulates the expression of a novel TCF7L2 non-coding transcript.\nAt time of import, last updated (by provider) on: Sep 20 2021\n\nContributors: ; [Mark A Frye, Thanh L Nguyen, Tamas Ordog, Brandon Coombes, Richard M Weinshilboum, Huaizhi Huang, Zhenqing Ye, Liewei Wang, Huanyao Gao, Daniel Kim, Jeong-Heon Lee, Brenna Sharp, Duan Liu, Joanna Biernacka]

As several psychiatric disorders share the same risk genes, we hypothesized that this microRNA could also be associated with attention-deficit/hyperactivity disorder (ADHD) and that this association to psychiatric disorders might be due to the variable number of tandem repeats (VNTR) polymorphism within the internal miR-137 (Imir137) promoter (PMID 18316599; PMID 25154622). To further understand the role of the microRNA 137 in the brain a knock-down of miR-137 expression in SH-SY5Y neuroblastoma cells was performed followed by expression analysis using a microarray.\nAt time of import, last updated (by provider) on: Aug 08 2019\n\nContributors: ; [Lena Weißflog, Andreas Reif, Stefanie Berger, Heike Weber, Claus J Scholz]

Notably, individuals suffering with these illnesses also have major disruptions in sleep and circadian rhythms, and disturbances to sleep and circadian rhythms can precipitate or exacerbate psychotic symptoms. Psychosis is associated with the striatum, though no study to date has directly measured molecular rhythms and determined how they are altered in the striatum of subjects with psychosis. Methods: Here, we perform RNA-sequencing and both differential expression and rhythmicity analyses to investigate diurnal alterations in gene expression in human postmortem striatal subregions (NAc, caudate, and putamen) in subjects with psychosis relative to unaffected comparison subjects. Results: Across regions, we find differential expression of immune-related transcripts and a substantial loss of rhythmicity in core circadian clock genes in subjects with psychosis. In the nucleus accumbens (NAc), mitochondrial-related transcripts have decreased expression in psychosis subjects, but only in those who died at night. Additionally, we find a loss of rhythmicity in small nucleolar RNAs and a gain of rhythmicity in glutamatergic signaling in the NAc of psychosis subjects. Between region comparisons indicate that rhythmicity in the caudate and putamen is far more similar in subjects with psychosis than in matched comparison subjects. Conclusions: Together, these findings reveal differential and rhythmic gene expression differences across the striatum that may contribute to striatal dysfunction and psychosis in psychotic disorders.\nAt time of import, last updated (by provider) on: Aug 31 2022\n\nContributors: ; [George Tseng, Colleen McClung, Wei Zong, Kyle Ketchesin]

Their non-Mendelian features such as monozygotic twins discordant for SCZ or BPD are likely complicated by environmental modifiers of genetic effects. 5-hydroxymethylcytosine (5hmC) is an important epigenetic marker in gene regulation and whether its links with genetic variants contribute to the non-Mendelian features remain largely unexplored. Here, we performed hydroxymethylome and genome analyses of blood DNA from psychiatric disorder-discordant monozygotic twins to study how allele-specific hydroxymethylation (AShM) mediates phenotypic variations. We identified thousands of genetic variants with AShM imbalances who exhibit phenotypic variation-associated AShM transition at regulatory loci. These AShMs have plausible causal associations with psychiatric disorders through effects on interactions between transcription factors, DNA methylations, or other epigenomic markers and then contribute to dysregulated gene expression, which eventually increases disease susceptibility. We then validated that competitive binding of POU3F2 on the alternative allele of psyAShM site rs4558409 (G/T) in PLLP can enhance the PLLP expression, while hydroxymethylated alternative allele alleviating the transcription factor binding activity at rs4558409 site might be associated with downregulated PLLP expression observed in BPD or SCZ. Moreover, disruption of rs4558409 induces gain of PLLP function and promotes neural development and vesicle trafficking. Our study provides a powerful strategy for prioritizing regulatory risk variants and contributes to our understanding of the interplay between genetic and epigenetic factors in mediating complex disease susceptibility.\nAt time of import, last updated (by provider) on: Oct 31 2023\n\nContributors: ; [Zhanwang Huang, Junping Ye]

To minimize genetic variation in gene expression levels between cases and controls we compared expression profiles in lymphoblastoid cell lines from monozygotic twin pairs discordant for the disease. We identified 82 genes that were differentially expressed by ? 1.3-fold in 3 BD1 cases compared to their co-twins, and which were statistically (p ? 0.05) differentially expressed between the groups of BD1 cases and controls. Using qRT-PCR we confirmed the differential expression of some of these genes, including: KCNK1, MAL, PFN2, TCF7, PGK1, and PI4KCB, in at least 2 of the twin pairs. In contrast to the findings of a previous study by Kakiuchi and colleagues with similar discordant BD1 twin design1 our data do not support the dysregulation of XBP1 and HSPA5. From pathway and gene ontology analysis we identified up-regulation of the WNT signalling pathway and the biological process of apoptosis. The differentially regulated genes and pathways identified in this study may provide insights into the biology of BD1.\nLast Updated (by provider): Jun 20 2007\nContributors:  Louisa Windus Nicholas Matigian Bryan Mowry Cheryl Filippich John McGrath Heather Smith Nicholas Hayward Christos Pantelis

CRXp-GFP reporter in H9 line replicates endogenous CRX expression when induced to form self-organizing 3-D retina-like tissue. We define temporal transcriptome dynamics of developing photoreceptors during the establishment of cone and rod cell fate. Our studies provide an essential framework for delineating molecules and cellular pathways that guide human photoreceptor development and should assist in chemical screening and cell-based therapies of retinal degeneration.\nLast Updated (by provider): Nov 14 2017\nContributors:  Kohei Homma Rossukon Kaewkhaw Anand Swaroop Koray D Kaya Jizhong Zou Mahendra Rao Matthew Brooks Vijender Chaitankar

We used microarray technology (Affymetrix HG-U133A GeneChips) to determine the expression of approximately 22 000 mRNA transcripts in post-mortem brain tissue (orbitofrontal cortex) from patients with bipolar disorder and matched healthy controls. Orbitofrontal cortex tissue from a cohort of 30 subjects was investigated and the final analysis included 10 bipolar and 11 control subjects. Differences between disease and control groups were identified using a rigorous statistical analysis with correction for confounding variables and multiple testing.\nNote: [] samples from this series, which appear in other Expression Experiments in Gemma, were not imported from the GEO source.
