Project description:To explore possible oncogenic factors in OS, we used a microarray-based approach to profile changes in the expression of mRNAs in five OS cell lines and human mesenchymal stem cells (hMSCs). We used a microarray-based approach to profile the mRNA expression of OS Human OS cell lines were analyzed with genome-wide expression arrays.

Project description:Di(2-ethylhexyl) phthalate (DEHP; CAS No. 117-81-7) belongs to the phthalate class of chemicals, and is commonly added to plastics for flexibility. DEHP has been identified as an index compound for group-TDI calculations owing to its extensive toxicological dataset. Humans are exposed to this ubiquitous environmental contaminant through multiple routes. DEHP has been designated as probably and possibly carcinogenic to humans based on its ability to induce rodent carcinogenicity, although the relevance of its mode of action (MoA) in humans remains unclear. The aim of this study was to investigate the carcinogenic potential of DEHP using an alternative method and explore the possible mode and mechanisms of action at the molecular level. Special attention has been paid to DEHP dissolution in cell media, leading to the use of a final concentration of 0.5% DMSO. Transcriptomics were conducted on cells treated with a cytotoxic concentration of DEHP (19.7 µg/mL) for 24 h. The aim of the microarray experiment was to analyze the molecular effects of the substance under the specific conditions of the Cell Transformation Assay protocol (BALB c/ 3T3 clone A31-1-1 CTA, according to the method validated by ECVAM, Sasaki et al., 2012), in order to provide mechanistic explanations of the test results derived from the CTA.
Project description:Competent oocytes can be discriminated by BCB staining. Positive stained oocytes are considered more competent than BCB negative oocyte, and injection of BCB+ oocyte extracted mitochondria into BCB negative oocytse can increase fertilisation and blastocyst rate. Here we have analysed the impact of mitochondrial supplementation on subsequent blastocyst transcriptome using agilent one color microarray that is specificly design to study the porcine embryo preimplantation period. Blastocysts were produced by intra cytoplasmic sperm injection (ICSI) from BCB positive and BCB negative oocytes as well as BCB negative oocytes supplemented with mitochondrial extract during ICSI (mICSI), and 3-4 single blatocyst transcriptomes were analysed for each group. 3-4 single blastocysts were analysed at the RNA level after whole transcriptome amplification, and level of gene expression was compared between groups, i.e ICSI BCB+ blastocysts (4), ICSI BCB- blastocysts (3) and mICSI BCB- blastocysts (4).
Project description:To investigate time-dependent changes the comprehensive gene expressions in colorectal normal and tumor surgical specimen within two hours. Both normal and tumor tissues were extracted at 0, 30, 60, 120 min after surgical removal in seven patients with locally advanced colorectal cancer and stabilized. RNA was extracted and calculated, time dependent changes of gene expression were examined by microarray data.
Project description:Inclusion body myopathy associated with Paget disease of bone and frontotemporal dementia (IBMPFD) is caused by mutations in the Valosin Containing Protein (VCP) gene on chromosome 9p12-13. To elucidate affected signaling transduction axes in IBMPFD, we determined expression profiles using microarray technology in quadriceps muscle from patients and unaffected relatives. Muscle from 10 individuals (7 affected, 3 unaffected first degree relatives) was obtained after informed consent for the muscle biopsy was obtained.
Project description:To identify dysregulated molecules between pterygium tissues and uninvolved conjunctiva tissues from the same eye, we performed whole genome microarray expression profiling. Total RNA from four pairs of pterygium and uninvolved conjunctiva tissues from the same eye was extracted and used for microarray experiments.
