Gene expression profile on the penile tissue of erectile dysfunction (ED) in cavernous nerve injury (CNI) RAT model

ABSTRACT: (Erectile dysfunction) ED during the radical prostatectomy (RP) treatment is caused by surgical injury of the cavernous nerve which is the final neuronal pathways of penile erection. We performed microarray experiment focused on theto understanding the gene signature alteration in the corporal cavernous tissue of the CNI-induced ED rat model. A total of 6 adult male Sprague-Dawley rats were randomly divided into two groups, sham operation (n=3) and bilateral CN resection (n=3) group. At 12 weeks after CN resection, penile tissue was harvested and microarray experiment was performed.

Gene expression signatures following nerve injury in a rat model (0h-9h)

Project description:We used microarrays to distinguish the gene expression differences among different time points after injury. We generated proximal sciatic nerve (SN) tissues (0.5cm) at 0h, 0.5h, 1h, 3h, 6h and 9h after sciatic nerve resection.

Gene expression signatures following nerve injury in a rat model (0d-14d)

Project description:We used microarrays to distinguish the gene expression differences among different time points after injury. We generated L4-6 dorsal root ganglia (DRG) tissues and proximal sciatic nerve (SN) tissues (0.5cm) at 0d, 1d, 4d, 7d and 14d after sciatic nerve resection.

Expression data from transgenic rice with anti-OsPDCD5

Project description:Environmental stresses influence the growth of plants and the productivity of crops. Salinity is one of the most important abiotic stresses for agricultural crops. PCD is induced by various biotic and abiotic stresses in algae and higher plants, including high salinity treatment. OsPDCD5, an ortholog to mammalian-programmed cell death 5, is up-regulated under low temperature and NaCl treatments. We found that the transgenic rice which constitutively expressed anti-OsPDCD5 increased salt stress tolerance in unique ways. By using the Rice Genome Microarray, we identi?ed target genes that were regulated in transgenic rice plants by anti-OsPDCD5. Leaf tissues of 2-week-old transgenic and nontransgenic seedlings (10 plants each) before 200mM NaCl treatment, 20mins and 3 hours after 200mM NaCl treatment, respectively, were selected.

Transcriptomic analysis of Clostridium acetobutylicum biofilm cells in repeated-batch fermentation

Project description:Previously, we performed DNA array-based transcriptomic analysis of Clostridium acetobutylicum biofilm adsorbed onto fibrous matrix in batch fermentation. Here, to further shed light on the transcriptomic modulation of maturing Clostridium acetobutylicum biofilm, we performed the DNA array-based transcriptomic analysis in repeated-batch fermentation. Significant time course changes in expression levels were observed for the genes involved in amino acid metabolism, oligopeptide ABC transporter, nitrogen fixation, and various other processes. Repeated-batch fermentation was carried out in 2-L stainless steel columns packed with 40 g of cotton towel ?cut into pieces?approximately 3 cm × 5 cm) containing 1.5 L of P2 medium. Medium circulation rate was maintained at 35 mL/min via a peristaltic pump and the temperature was controlled at 37°C. Fermentation broth was replaced with fresh P2 medium every 12 h. Samples were withdrawn at 6 h after the medium replacement at predetermined interval, except for the last 3 samples. The last 3 samples were withdrawn at 12 h, 15 h, and 17 h after the medium replacement, respectively, to study the transcriptomic response to the adverse condition at the end of fermentation. A total of 8 samples were withdrawn over a period of 7 days, and time course gene expression profiles were studied.

Transcriptomic analysis of Clostridium acetobutylicum biofilm cells adsorbed onto fibrous matrix in biobutanol production [I]

Project description:Immobilization of Clostridium acetobutylicum B3 onto fibrous matrix by surface-adsorption was developed and applied to biobutanol production. The immobilized C. acetobutylicum B3 cells formed biofilm and showed dramatically improved butanol tolerance and production rate. DNA array-based transcriptional analysis of C.acetobutylicum B3 biofilm cells was conducted to elucidate the gene expression profile of the biofilm cells. Results showed that about 16% of the whole genome was differentially expressed. The most apparently differentially expressed genes were involved in amino acid transport and metabolism, inorganic ion transport and metabolism, energy production and conversion, and coenzyme transport and metabolism. Samples for biofilm cells and planktonic cells were withdrawn at four diffierent fermentation phases. The gene expression pattern of biofilm cells were investigated relative to that of planktonic cells from the same phase. The experiment was carried out twice independently. Cotton fibrous matrix (60 g/L) was used as biofilm carrier.

MiRNA expression pattern in different prognosis of colon cancer patients

Project description:We measured the expression of human microRNAs in tumor cells derived from 8 FFPE samples among non-invasive CRC patients with different prognosis. Patients lived for more than 5 years after surgery were classified as good prognosis, and patients died within 5 years from surgery were classified as poor prognosis. Tumor tissues were macrodissected under the control HE staining slides. And there were at least 75 percent cancer cells in the samples. MicroRNA microarray was used to measure the expression of human miRNAs in tumor cells derived from 8 FFPE samples among early stage CRC patients with different prognosis.

Gene expression in human prostate cancer cell lines regulated by HIC1 gene

Project description:This study aimed to further our understanding of the role that hypermethylatioted in cancer 1 (HIC1) plays in prostate cancer (PCa) development. Microarrays were searched for some genes that had correlated expression with HIC1 mRNA. Our data showed that HIC1 promoter hypermethylation was presented in cell lines, tissues and plasma of PCa patients. According to fold-change screening between restoring expression of HIC1 and its respective control cells, both up-regulated and down-regulated genes were commonly observed in PC3 and C4-2B cells. The restoring expression HIC1 in PCa lines were respectively noted as PC3-HIC1 and C4-2B-HIC1 cells, and the respective controls were noted as C4-2B-GFP and PC3-GFP cells.

DNA microarray analysis of global gene regulation by AdpAch in Streptomyces chattanoogensis

Project description:The effects of AdpAch on transcription of all protein-coding genes of S. griseus were evaluated by comparison of the transcriptomes of the wild-type to that of the ∆adpAch mutant strain We compared the pattern of gene expression of the wild-type (WT) to that of the ∆adpAch mutant strain. Mycelium was harvested after 16h, 24h, and 36h of growth and RNA was isolated from three independent cultures of each strain. For DNA microarray analysis of mutant strains, we considered a fold change of ≥2 and ≤0.5 of that of the WT strains, respectively, with a P-value <0.05 to be significant. According to these criteria, approximately 1400 genes were differentially expressed at all time points
