MicroRNAs among esophageal cancer cell sublines with different migration ability

ABSTRACT: Cellular directed migration is critical to invasion-metastasis cascade of cancer cells. We used in vitro transwell model to screen two esophageal cancer cell lines (KYSE30/180) and obtained two pairs of subpopulations with distinc motiliyt ability. Then we used microarrays to detail the differentially expressed genes and microRNAs between these two cell sublines (30U/D and 180U/D) to identify those responsible for ESCC motility. KYSE30/180 cells were subject to four successive selections using transwell (CORNING, USA). Subpopulations penetrated through membrane (D) or not (U) were harvested respectively for RNA extraction and hybridization on Affymetrix genome and LC Sciences microRNA microarrays

Sperm miRNA expression differences between bulls consuming toxic and non-toxic tall fescue seed

Project description:The objectives of our study were to identify microRNA (miRNA) present in bovine sperm and to evaluate the effects of fescue toxicosis on sperm miRNA expression. Angus bulls were assigned to treatments of either toxic or non-toxic fescue seed diets. Semen was collected and subjected to microRNA (miRNA) isolation after 126 days. Three bull's sperm miRNA samples from each treatment group were chosen and pooled for deep sequencing. Sequencing results were used to create a custom microarray for miRNA comparison between groups. LC Sciences was used as a service provider for the sequencing and custom microarray.

RNA-seq of the anterior third (head) region of fifty pooled danio rerio embryos at the 15-somite stage following crispld2 morpholino knockdown compared to uninjected controls

Project description:We have a well characterized crispld2 morpholino in the danio rerio organism system. The aim of this experiment was to determine differential gene expression in the morpholino zebrafish compared to uninjected zebrafish.

Genome-wide identification and analysis of microRNA expression in mouse neuroblastoma cells (NA) and BV-2, a murine microglial cell line, infected with rabies virus CVS-11 (Challenge virus standard)

Project description:Rabies virus (RABV) infection led to alteration of microRNA expression in NA and microglia. A sixteen-chip study was performed using total RNA isolated from NA and microglia infected with rabies virus CVS-11 (Challenge virus standard) or mock infected as a control. RNA was isolated from microglia at 12, 24, or 48 hpi and from NA at 24 hpi.

miRNA expression profiling of NB4 control cells versus NB4 cells treated with SAHA (Vorinostat)

Project description:For a long time, the BARD1 (BRCA1-associated RING domain 1) protein has been considered as a BRCA1 (BReast Cancer susceptibility gene 1, early onset) interactor, and tumor suppressor mutated in breast and ovarian cancers. Despite its functions in a stable heterodimer with BRCA1, there is increasing evidence for BRCA1-independent functions of BARD1. Here, we investigated BARD1 expression and function in human acute myeloid leukemias and their modulation by epigenetic mechanisms and microRNA. We show that the HDACi (histone deacetylase inhibitor) Vorinostat reduces BARD1 mRNA levels by increasing miR-19a and miR-19b expression levels. Moreover, we identify specific BARD1 isoforms that might act as tumor diagnostic and prognostic markers. Two-condition experiment: untreated NB4 cells (control) vs. NB4 cells treated with 5M-BM-5M SAHA (Vorinostat) for 6h. Biological replicates: 3 control, 3 treated, independently grown and harvested at 6 hours. One replicate per array.

Genome-wide identification and analysis of microRNA expression in brains of mice infected with FJDRV, a street rabies virus with high virulence, and ERA, a laboratory-adapted virus with lower virulence

Project description:Host-virus interaction was analyzed at microRNA expression level. The hypothesis tested in the present study was that rabies virus (RABV) infection affects the microRNA expression in brains of mice and RABV with different virulence induce distinct microRNA expression pattern in host. Results provide important information that RABV infection led to alteration of microRNA expression in brains of mice and FJDRV, a street rabies virus with highly virulence isolated from brain of rabid dog in Fujian provice of China, or ERA, a laboratory-adapted rabies virus with lower virulence induced different microRNA expression pattern, and some them may involved in host defense and immune-related function. An nine chip study was performed using total RNA isolated from brains in Treatment 1, three BALB/c mice infected with FJDRV, Treatment 2, three BALB/c mice infected with ERA, and Control, three BALB/c mice non-infected.
