Detection, treatment, and prediction of outcome for lung cancer patients increasingly depend on a molecular understanding of tumor development and sensitivity of lung cancer to therapeutic drugs. The application of genomic technologies, such as microarray, is widely used to monitor global gene expression and has built up invaluable information and knowledge, which is essential to the discovery of new insights into the mechanisms common to cancer cells, resulting in the identification of unique, identifiable signatures and specific characteristics. It is likely that application of microarray may revolutionize many aspects of lung cancer being diagnosed, classified, and treated in the near future. We used microarrays to detail the global gene expression patterns of lung cancer.

View SamplesThe purpose of this study was to profile gene expression changes that could occur with the loss of co-repressor SLIRP. In addition, we wanted to investigate how DHT could further alter gene expression. Methods: LNCaP cells were transfected with custom nonsense control siRNA or a pool of SLIRP siRNA (HSS130109, HSS188666, HSS188667 Invitrogen, Carlsbad, CA) at 40nM for 24hrs. Cells were washed once with PBS and replaced with SFM containing EtOH or 1nM/ml DHT for another 24hrs. Two biological replicates were collected from 2 different experiemnts for total of 4 replicates. RNA collected was sequenced using Illumia HiSeq2000 single read 50 bp by the HTSF core at UNC and aligned and normalized by the Bioinformatics core at UNC. Results: We found a differential gene expression pattern between our control and SLIRP knockdown samples. We also identified a 176 AR gene signature with 3 subclasses and a large SLIRP gene signature (~1700). Overall design: Examination of control (NS) vs. SLIRP siRNA treated with 1nM DHT in the prostate cancer cell line LNCaP
Interaction between androgen receptor and coregulator SLIRP is regulated by Ack1 tyrosine kinase and androgen.

View SamplesTransformation of Glycine max with seed-targeted expression vectors via Agrobacterium causes measurable unscripted gene expression changes in the seed transcriptome Overall design: mRNA was sequenced from three transgenic events expressing three different recombinant proteins in soybean seeds. Three plants were chosen from each as group replicates, and three seeds from each plant as individual biological replicates.

Subject
View SamplesThe aim of this study was to determine the changes in gene expression of rice root tips when they came in to contact with a hard layer (60% wax layer). Three categories of root tips were sampled; tips before the hard layer, tips that had come into contact with the hard layer and root tips which had buckled after coming into contact with the hard layer.

View SamplesMaternal environment is an important regultor of seed dormancy, but the mechanisms underlying the process are poorly understood. We have found that genes in the circadian clock control dormancy, in part through their regulation of the canonical photoperiod pathway known from research into flowering time control. In this experiment we compare the affects of altering seed maturation temperature or maternal photoperiod on dry seed transcriptomes, and the photoperiod-insenstive ft-1 mutant to wt type Ler. In this way we are identifying gene expression programmes which result from the seed's response to maternal environmental experience.
Induction of dormancy in Arabidopsis summer annuals requires parallel regulation of DOG1 and hormone metabolism by low temperature and CBF transcription factors.

View SamplesPurpose: To identify differntially expressed transcripts in TP-0903 treated embryos that impair cranila NC EMT and cell migration in zebrafish embryos Methods: zebrafish embryos treated at 13 hpf with 5-7uM TP-0903 and DMSO for 1-, 4- and 8-hrs at 28°C. 35 embryos were collected for each treatment. Results: TP-0903 increases expression of several retinoic acid target genes including genes from within the retinoid pathway Conclusions: TP-0903 causes a direct increase in RA signaling that impairs cranial NC EMT and cell migration in zebrafihs embryos Overall design: mRNA profiles of zebrafish embryos treated with TP-0903 and DMSO were generated by RNA-Seq, in quadruplicates, using Illumina Hi Seq

View SamplesA consistent clinical feature of amyotrophic lateral sclerosis (ALS) is the sparing of eye movements. Pathological studies have confirmed that there is relative sparing of the cranial motor nuclei of the oculomotor, trochlear and abducens nerves, although pathological changes resembling those seen in anterior horn cells are present to a lesser degree. The aim of the present study is to combine LCM and microarray analysis to study the differences between motor neurons that are selectively resistant (oculomotor neurons) and those that are vulnerable (lumbar spinal motor neurons) to the disease process in amyotrophic lateral sclerosis.
Unravelling the enigma of selective vulnerability in neurodegeneration: motor neurons resistant to degeneration in ALS show distinct gene expression characteristics and decreased susceptibility to excitotoxicity.
