Therefore, it is to be regretted that a comprehensive review of our present knowledge of the group does not exist, which does not only cause the faulty way in which the Priapulida are treated usually in textbooks and works on phylogeny, but also hampers further studies. -
Additional Methods
Additional Methods Cell Expression Profiles The tissue-dependent gene expression dataset from the Genome Novartis Foundation contains 32 healthy major tissues, and 47 tumour samples and cell lines. The custom- designed whole-genome gene expression microarrays used on each sample targets 44775 human mRNA transcripts. Previous analysis of this dataset identified many chromo- somal regions of correlated transcription that are under the control of both tissue and parental allele-specific expression. The expression levels of TF genes across tissue sam- ples are observed to be lower than non-TF genes. This is coherent with the mechanistic explanation that the effect of a single TF molecule is amplified by transcribing many copies of mRNA from a target gene. Across all samples, the proportion of TFs rel- ative to all expressed genes is remarkably stable at ∼ 6%. In the bootstrap test for highly predictive CRMs, we resampled from this set of TFs to generate the bootstrap replicates. High variance in gene expression profiles are observed between replicates for samples with more heterogeneous composition. Therefore, we treat each replicate as an independent sample in our analysis. When analyzing expression variation in a single sample, we found that a Gaussian distributional assumption for gene expression is more suitable compared to other distributions. Smoothing and Model Fitting Since gene expression response by the target gene varies over different TF expression values in a smooth fashion, a curved function is needed to fit our gene expression data. For additive models, the partial response of the target gene to the expression of each TF is described by a smooth function. -

Of particular importance are gene families involved in the mediation of detoxification responses, such as members of the nuclear receptor subfamily 1 group I (NR1I), the pregnane X receptor (PXR), and the constitutive androstane receptor (CAR). While documented in multiple vertebrate genomes, PXR and CAR display an intriguing gene distribution. PXR is absent in birds and reptiles, while CAR shows a tetrapod-specific occurrence. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

Mouse Anti-Human Testicular Receptor 4
Catalog Clonality, clone Reactive Reg. Product Name Quantity Applications Number (isotype) species Status mAb clone H0107B WB, ELISA, 434700 Mouse anti-human TR4 100 µg Hu, Ms, Rt RUO (Ms IgG2a) IP, IHC Mouse Anti-Human Testicular Receptor 4 Description Testicular receptor 4 (TR4, TAK1; NR2C2) is a member of the orphan nuclear receptor family. TR4 was originally cloned from lymphoblastoma Raji cells or mouse brain cDNA library. No ligand has been reported. Northern blot shows TR4 is transcribed as a 9kb mRNA in many tissues and as a 2.8kb mRNA in testis, mainly in spermatocytes. TR4 has two isoforms called TR4α1 and TR4-α2, which differ in 19 amino acids coded by two separate exons. Both products translated from 9kb transcript are ubiquitously expressed. Since TR4 binds to the same elements for the RAR-RXR or TR-RXR heterodimers, TR4 may have an inhibitory affect for retinoic-acid mediated transactivation. Nomenclature NR2C2 Genbank L27586 Origin Produced in BALB/c mouse ascites after inoculation with hybridoma of mouse myeloma cells (NS-1) and spleen cells derived from a BALB/c mouse immunized with Baculovirus-expressed recombinant human TR4 (23-52 aa). Specificity This antibody specifically recognizes human TR4 and cross reacts with mouse and rat TR4.

Mouse Tmem106c Knockout Project (CRISPR/Cas9)
https://www.alphaknockout.com Mouse Tmem106c Knockout Project (CRISPR/Cas9) Objective: To create a Tmem106c knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Tmem106c gene (NCBI Reference Sequence: NM_201359 ; Ensembl: ENSMUSG00000052369 ) is located on Mouse chromosome 15. 8 exons are identified, with the ATG start codon in exon 2 and the TAG stop codon in exon 8 (Transcript: ENSMUST00000064200). Exon 2~8 will be selected as target site. Cas9 and gRNA will be co-injected into fertilized eggs for KO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Exon 2 starts from about 0.13% of the coding region. Exon 2~8 covers 100.0% of the coding region. The size of effective KO region: ~4867 bp. The KO region does not have any other known gene.

PhysicalState: Liquid Label Unconjugated Host Rabbit Gene Name NR2C1 Species Reactivity mouse, human, rat Storage Condition Store vial at -20° C prior to opening. This product is stable at 4° C as an undiluted liquid. For extended storage, aliquot contents and freeze at -20° C or below. Avoid cycles of freezing and thawing. Dilute only prior to immediate use. Synonyms Nuclear receptor subfamily 2 group C member 1, Orphan nuclear receptor TR2, mTR2 Application Note Anti-Testicular Receptor 2 (Rabbit) antibody is suitable for use in Western Blots. Anti-Testicular Receptor 2 antibodies are specific for the ~64 kDa TR2 protein in Western blots of testes and nuclear extracts from MEL cell lines. Researchers should determine optimal titers for applications that are not stated below. Background TR2 antibody detects Testicular receptor 2 (TR2), which is a member of the orphan nuclear receptor family. It is widely expressed at a low level throughout the adult testis. TR2 represses transcription and binds DNA directly interacting with HDAC3 and HDAC4 via DNA-binding domains. TR2 has also been implicated in regulation of estrogen receptor activity in mammary glands. In addition, TR2 has recently been shown to form a heterodimer with TR4 that can bind to the direct repeat 6 element of the hepatitis B virus (HBV) enhancer II region thus suppressing HBV gene expression. -
