Affymetrix Human Transcriptome Array 2.0 (hta20)
Description
Low back pain (LBP) is one of the most prevalent conditions which need medical advice and result in chronic disabilities. Degenerative disc disease (DDD) is a common reason for LBP. A lot of researchers think that CEP degeneration play critical roles in the initiation and development of DDD. In recent years, researchers have put interests on cell-based therapies for regenerating disc structure and function. Our research team has isolated cartilage endplate-derived stem cells (CESCs) and validated their chondrogenic and osteogenic differentiation ability. Enhanced chondrogenic differentiation and inhibited osteogenic differentiation of CESCs may retard CEP calcification and restore the nutrition supply, possibly regenerating the degenerated discs.

Description
Interleukin 7 receptor (IL7R) is a transmembrane receptor which belongs to the type I cytokine receptor family. Recent studies have indicated that the IL7R is involved in the pathogenesis of some neurodegenerative disorders, such as multiple sclerosis. Previously, we found that the retinal neuroregenation was delayed following the targeted knockdown of IL7R, highlighting the potential role of IL7R in the development of nervous system.

Illumina HiSeq 2500
Description
We carry out a differential RNAseq analysis of a row of sensilla on the anterior wing margin and find expression of many genes associated with pheromone and chemical perception. Overall design: We collected wings from wild type and from Poxn mutants that lack chemosensory sensilla on the wing. We performed RNAseq on three biological replicates from each genotype.
Publication Title
Chemosensory sensilla of the Drosophila wing express a candidate ionotropic pheromone receptor.

Description
Huntington disease (HD) is associated with increased nuclear accumulation of the repressor element-1 silencing transcription factor (REST) which govens a huge gene network. An alternative REST splicing event (E3) eliminates a motif essential for nuclear targeting of REST.

Description
RNA sequences (from RNA-seq) from the tissues of longissimus dorsi muscle of two indigenous Chinese pig breeds (Diannan Small Ear pig [DSP] and Tibetan pig [TP]) and two introduced pig breeds (Landrace [LL] and Yorkshire [YY]) were examined using HiSeq 2000 to identify and compare the differential expression of functional genes related to muscle growth and lipid deposition. We obtained 27.18 G clean data through the RNA-seq and detected that 18,208 genes were positively expressed and 14,633 of them were co-expressed in the muscle tissues of the four samples. In all, 315 DEGs were found between the Chinese pig group and the introduced pig group, 240 of which were enriched with functional annotations from the David database and significantly enriched in 27 Gene Ontology (GO) terms that were mainly associated with muscle fiber contraction, cadmium ion binding, response to organic substance and contractile fiber part. Based on functional annotation, we identified 85 DEGs related to growth traits that were mainly involved in muscle tissue development, muscle system process, regulation of cell development, and growth factor binding, and 27 DEGs related to lipid deposition that were mainly involved in lipid metabolic process and fatty acid biosynthetic process. Overall design: RNA sequences from the tissues of longissimus dorsi muscle of two indigenous Chinese pig breeds (Diannan Small Ear pig [DSP] and Tibetan pig [TP]) and two introduced pig breeds (Landrace [LL] and Yorkshire [YY]) were examined using HiSeq 2000.

Description
To compare circadian gene expression within highly discrete neuronal populations, we separately purified and characterized two adjacent but distinct groups of Drosophila adult circadian neurons: the 8 small and 10 large PDF (pigment-dispersing factor)-expressing ventral lateral neurons (s-LNvs and l-LNvs, respectively). The s-LNvs are the principal circadian pacemaker cells, whereas recent evidence indicates that the l-LNvs are involved in sleep and light-mediated arousal. Although half of the l-LNv-enriched mRNA population including core clock mRNAs is shared between the l-LNvs and s-LNvs, the other half is l-LNv- and s-LNv specific. The distribution of four specific mRNAs is consistent with prior characterization of the four encoded proteins and therefore indicates successful purification of the two neuronal types. Moreover, an octopamine receptor mRNA is selectively enriched in l-LNvs, and only these neurons respond to in vitro application of octopamine. Dissection and purification of l-LNvs from flies collected at different times indicate that these neurons contain cycling clock mRNAs with higher circadian amplitudes as well as at least a 10-fold higher fraction of oscillating mRNAs than all previous analyses of head RNA. Many of these cycling l-LNv mRNAs are well-expressed but do not cycle or cycle much less well elsewhere in heads. The results suggest that RNA cycling is much more prominent in circadian neurons than elsewhere in heads and may be particularly important for the functioning of these neurons.

Description
Here we show that biotin-labelled miR-34a can be loaded to AGO2, and AGO2 immunoprecipitation can pulldown biotinylated miR-34a (Bio-miR pulldown). RNA-sequencing (RNA-seq) of the Bio-miR pulldown RNAs efficiently identified miR-34a mRNA targets, which could be verified with luciferase assays. In contrast to the approach of Bio-miR pulldown, RNA-seq of miR-34a overexpression samples had limited value in identifying direct targets of miR-34a. It seems that pulldown of 30 -Biotin-tagged miRNA can identify bona fide microRNA targets at least for miR34a. Overall design: biotin-labelled miR-34a pulldown and RNA sequencing of miR-34a overexpression samples
