Transcription profiling of MCF7 (human mammary gland adenocarcinoma) cells deprived of serum for 30 hrs and vs non-deprived cells to test spike based normalization

ABSTRACT: MCF7 (human mammary gland adenocarcinoma) cells were deprived of serum for 30 hrs and were compared to non-deprived cells. External normalization controls were added in equal amounts to equivalent amounts of total RNA.

EMBO reports 20030401 4

Expression profiling is a universal tool, with a range of applications that benefit from the accurate determination of differential gene expression. To allow normalization using endogenous transcript levels, current microarray analyses assume that relatively few transcripts vary, or that any changes that occur are balanced. When normalization using endogenous genes is carried out, changes in expression levels are calculated relative to the behaviour of most of the transcripts. This does not refl ...[more]

Transcription profiling of Drosophila expressing four mutant forms of MYOC (R342K, Q368X, D380N and K423E) to model Myocilin-Associated Glaucoma

Project description:We have established Drosophila melanogaster as a model system for ocular hypertension by expressing wild-type human myocilin (MYOC) in the Drosophila eye. Here, we have created transgenic flies that express four clinically relevant mutant forms of MYOC (R342K, Q368X, D380N and K423E) in their eyes using the gmr-Gal4/UAS binary system. We compare and identify human glaucoma candidate genes based on the transcription profiles of flies that express wt-MYOC or mutant-MYOCs.

Transcription profiling of heptatocytes from mice given a high-copper diet

Project description:In order to study the physiological consequences of a high-copper diet on hepatic gene expression, 6 mM CuCl2 was added to the drinking water for a period of 1 month. After this period, livers of seven control mice and eight copper-treated mice were isolated and were subjected to microarray analysis and copper measurements. The hepatic gene expression profile of copper-treated mice was compared to non-treated mice using a pooled reference.

Transcription profiling of six pairs of affected and non-affected male F2 mice selected on the basis of their motor activity levels

Project description:Mice were obtained from in house breeding of C57BL/6J and C57BL/6J-Chr 1A/Na breeding pairs (Jackson Laboratories, USA). To produce F1 hybrids, C57BL/6J females were mated with C57BL/6J-Chr 1A/Na males. The F1 hybrids were intercrossed, producing 82 F2 progeny (41 males and 41 females). Microarray analysis was performed on six pairs of affected and non-affected male animals from the F2 progeny selected on the basis of their motor activity levels (average daily levels of distance moved over a 3 days recording: 768±74 cm/hr (affected) versus 1765±175 cm/hr (non-affected)(p<0.0001).

Transcription profiling of honey bee queens treated with carbon dioxide and physical manipulation vs virgin controls

Project description:Mating is a complex process that causes many behavioral and physiological changes, but the factors triggering these changes and the underlying molecular processes are not well characterized. Honey bee queens provide a convenient system for dissecting these factors (e.g., physical manipulation, insemination volume, insemination substance) via instrumental insemination. We examined the effects of carbon dioxide (CO2), a commonly used anesthetic in instrumental insemination that causes changes similar to those observed after mating, and physical manipulation, which presumably mimics the act of copulation, on the brain transcriptional changes in honey bee queens. We found significant gene overlap between our study and previous mating studies in honey bee queens and Drosophila. This suggests that molecular pathways regulating the mating process are conserved across different mating regimes of honey bees as well as across insect orders.

Transcription profiling of homozygous Commd1 null mouse embryos to elucidate the underlying mechanism leading to embryonic lethality

Project description:A gene expression study using microarray analysis was performed to elucidate the underlying mechanism leading to embryonic lethality in homozygous Commd1 null (Commd1-/-) mouse embryos. A gene expression profile of 9.5 dpc Commd1-/- embryos were generated and were compared to a gene expression profile of both 8.5 dpc and 9.5 dpc normal embryos.

Impact of Nosema apis infection on worker honey bee fat body gene expression

Project description:Newly emerged adult workers (24 hours old) were infected with 50,000 Nosema apis spores in sucrose solution. Controls were fed sucrose. Workers were maintained in cages in an incubator and collected at 2 and 7 days post-infection. Fat body tissue was dissected (eviscerated abdomen) and whole genome expression in this tissue was compared across treatments and collection time points using microarrays.
