Gene expression of the pigmented and non-pigmented epithelia of the ciliary body of human healthy eyes

ABSTRACT: The ciliary body (CB) of the human eye consists of the non-pigmented (NPE) and pigmented (PE) neuro-epithelia. We investigated the gene expression of the NPE and PE, to shed light on the molecular mechanisms underlying the most important functions of the CB. Therefore we isolated NPE and PE cells from seven healthy human donor eyes using laser dissection microscopy. Next, we performed RNA isolation, amplification, labeling and hybridization against 44k Agilent microarrays. We performed the microarrays against a common reference sample, namely human RPE/choroid RNA. We performed 7 replicates of PE samples from 7 different donors and 7 NPE replicates from the same 7 different donors.

Gene expression of the mouse choroid plexus epithelium (CPE)

Project description:We investigated the gene expression of the mouse CPE. We isolated CPE cells from three mouse brains with laser dissection microscopy. Next, we performed RNA isolation, amplification, labeling and hybridization against 44k Agilent microarrays. We performed the microarrays against a common reference sample, which was mouse RPE/choroid RNA. We performed 3 mouse CPE replicates from 3 different mouse from the same strain, namely C57BL/6 .

Transcription profiling of nouse pigmented epithial cells

Project description:Adult (6- to 8-week-old) C57BL/6 purchased from CLEA Japan Inc. (Tokyo, Japan) were used as donors ocular pigment epithelium (PE). To cultivate retinal PE (RPE) eyes were cut into two parts along a circumferential line posterior to the ciliary process, creating a ciliary body-deficient posterior eyecup. The eyecup was then incubated in 0.2% trypsin (Biowhitaker) for 1 hr. These tissues were triturated to make a single cell suspension, and then re-suspended in the medium. Experiment Overall Design: Comparison of gene expression pattern in Mouse Primary Cultured Cell Lines (RPE, RPE+IFNg).

SWATH-based quantitative proteomics data derived from whole grain of Malaysian local pigmented and non-pigmented rice varieties

Project description:Information about protein expression in rice grain across both pigmented and non-pigmented rice varieties is still relatively scarce. The data provided here represent proteomic data obtained from selected 6 Malaysian local rice varieties with varying pigmentations (black, red and white). The selected pigmented rice varieties such as black (BALI and Pulut hitam 9) and red rice (MRQ100 and MRM16) have shown high antioxidant activities and non-pigmented rice (MRQ76 and MR297) contain amino acid and micronutrient contents. This project aimed to obtain global protein expression profile as well as differential protein expression between the selected pigmented and non-pigmented rice varieties particularly proteins with their functions responsible for nutritional (i.e. antioxidant, folate and low glycaemic index) and quality (i.e. aromatic) traits. Integration of this proteomics dataset with other available in-house omics data could facilitate the identification of significant functional markers related to nutritional and quality traits. Total proteins were prepared from dehusked matured seeds harvested from three different rice plants of each variety (3 protein samples per variety). The proteins were trypsin digested before subjected to SWATH-MS proteomics analysis. Proteins were identified by matching tandem mass (MS/MS) spectra from both 1D and 2D IDA to Oryza sativa japonica and indica rice databases available at UniProt by using ProteinPilot software (v4.2) (AB Sciex). Quantification of proteins was carried out by determining protein peak areas extracted from SWATH analysis data sets using PeakView (v2.1) (AB Sciex) software. Differentially expressed protein between varieties were identified using T-test analysis with a set threshold for fold change ± 1.5 and p‐value < 0.05.

Expression data from non-pigmented and pigmented mouse melanocytes

Project description:Immortalized, amelanotic melanocytes isolted from skin of Balb/c express enzymatically-inactive tyrosinase due to a homozygous point mutation (TGT->TCT) in tyrosinase gene, resulting in a lack of melanin . To serve as a control cell line, pigmentation was restored in these cells by correcting the point mutation using an RNA-DNA oligonucleotide (kingly gift from Dr. Alexeev Y. Vitali). We used microarray to detail the effect of tyrosinase mutation on gene expression in normal versus mutant melanocytes. Pigmented and non-pigmented melanocytes were grown for RNA extraction and hybridization on Affymetrix microarrays. We used both normal and mutant melanocyte in order to obtain expression profiles. We then examined variances in gene expression between the two cell lines.
