Project description:The objective of this study was to identify changes in gene expression levels between wild-type and CFTR-knockout small intestine. CFTR-knockout mice (provided by Dr. Lane Clarke of the University of Missouri) were maintained on colyte. Keywords: gene expression comparison Four wild-type and four CFTR-knockout small intestinal RNA samples were compared. To facilitate statistical analysis and reduce affects of Cy3 and Cy5 labeling, comparison of two WT and two KO were repeated with a dye flip.
Project description:This experiment was investigating how gut commensal bacteria and intestinal inflammation affect miRNA expression. We analyzed miRNA expression of spleen and intestine from specific pathogen free (SPF) B6 mice, germ-free (GF) B6 mice, and IL-10 knockout mice which have severe colitis by microarray. Thus we have total 6 samples: GF spleen; GF intestines; SPF spleen; SPF intestine; IL-10 KO spleen and IL-10 KO intestine. We directly isolated RNA from whole spleens or intestines without any treatments, and then did microarray analysis.
Project description:OE17 and OE23 are chloroplast targeted proteins. RNA co-immunoprecipitation was performed using antibodies raised against these proteins. RNA from the pellet and from the supernatent for each pulldown was labeled with different fluoro-dyes.
Project description:Co-immunoprecipitation of the maize pentatricopeptide protein PPR4 and extraction of bound RNA. RNA is labelled and hybridized to a maize chloroplast genome tiling array in order to identify target RNA species of PPR4.
Project description:Identification of target transcripts for the putative chloroplast RNA binding protein CFM2 in Zea mays. CFM2 was immunoprecipitated from a chloroplast extract. Chloroplast extracts were prepared from WT tissue. RNA from the pellet and from the supernatant for each pulldown was labelled with different fluoro-dyes and hybridized onto an array covering the complete maize chloroplast genome. Messages enriched in the immunoprecipitate from WT tissue are likely targets for CFM2.
Project description:The objective of this study was to identify changes in gene expression levels between wild-type and AE2-knockout colon. 7 wild-type and 7 AE2-null colon RNA samples were compared to identify genes that are differentially expressed in the colon of AE2 knockout mice. Total RNA was collected from both male and female wild-type and AE2-null colons (including both proximal and distal colon) when the mice were 18 days old. All pairs were gender- and aged-matched, and all mice were on a mixed 129 Black Swiss background. To facilitate statistical analysis and reduce any affects of Cy3 and Cy5 labeling, comparisons of two wild-type and two AE2-null samples were repeated using a dye flip.
Project description:The objective of this study was to identify changes in gene expression levels between wild-type and NKCC1-knockout small intestine. 6 wild-type and 6 NKCC1-knockout small intestine RNA samples were compared. Total RNA was collected from both male and female 8-week old wild-type and NKCC1-null mice on an inbred FVB\N background. All comparisons were done between wild-type and NHE4-null samples from age- and gender-matched mice.
