Transcription profiling of nouse intestinal epithelial cells of germ-free versus wildtype mice

ABSTRACT: Gene expression was analyzed in intestinal epithelial cells of germ-free and wildtype mice. Experiment Overall Design: Ileums and proximal colons of 4 C57/Bl6 control and 4 C57/BL6 germ-free mice were collected and embedded in OCT. Tissue sectioned (10 mikroM) and laser capture microscopy was performed using a Zeiss/Palm laser capture system. Total RNA was extracted from about 16000 cells of the catapulted samples using RNA microprep kit (Stratagene). These 16 000 cells derive from all 4 animals (pooled approx. 4 000 cells from each mouse). We retrieved between 50 and 150 ng total RNA. Fourty ng total RNA was expanded by two rounds of in vitro cRNA amplification and affymetrix genechip Moe403 were probed at the Swegene Resource Center Lund, Sweden. Array data analysis was performed using dCHIP2004 software.

A gene expression atlas of early craniofacial development

Project description:We present a gene expression atlas of early mouse craniofacial development. Laser capture microdissection (LCM) was used to isolate cells from the principal critical micro-regions, whose development, differentiation and signaling interactions are responsible for the construction of the mammalian face. We examined the facial mesenchyme and adjacent neuroepithelium at E8.5, at E9.5, facial mesenchyme, olfactory placode/epidermal ectoderm, underlying neuroepithileium, and emerging mandibular and maxillary arches. AT E10.5 we sampled the medial and lateral prominences, olfactory pit, multiple regions of the underlying neuroepithelium the mandibular and maxillary arches, and Rathke's pouch. For these 103 samples, laser capture microdissection from serial and bioreplicated E8.5, E.9.5, and E10.5 frozen sections was used to make RNA using the ZR RNA MicroPrep kit (Zymo). Nugen RiboSpia Ovation Pico WTA System V2 was used target amplification. We used starting total RNA of at least 2 ng.

Expression data from lung tumors of KrasTgfbr2 -/- mouse model

Project description:Recent data suggests that repression of the Type II TGF-B Receptor (Tgfr2) repression in human lung adenocarcinoma is important for progression from noninvasive to invasive adenocarcinoma. To test this hypothesis in a animal model of non-invasive lung cancer, we generated an inducible, lung specific Tgfbr2 knockout model in the oncogenic Kras mouse. LSL-KrasG12D positive mice were simultaneously backcrossed to C57/Bl6 mice and to the Tgfbr2 flox/flox mice. To induce tumors, 100 _l of saline containing 3x10e10 particles of an adenovirus containing the Cre recombinase (Ad.Cre) was administered to each LSL-KrasG12D mouse intra-nasally. Mice were sacrificed at 7 weeks after administration of Adeno-Cre. We used laser capture microdissection to acquire tumor cells from KrasTgfbr2-/- and KrasTgfbr2 wt mouse tumors.

Testis samples from Alkbh1 wild-type and KO mice

Project description:The aim of the study was to elucidate the role of Alkbh1 by targeted deletion in C57/BL6 mice. Alkb deficiency results in sex-ratio distortion of offspring and apoptosis in adult testes, most likely caused by defects in the pachytene stage during spermatogenesis. Due to the pivotal role of Alkbh1 in mouse survival and potentially in germ cells, we searched for Alkbh1-regulated genes in adult testes.
