Transcriptional targets of Trps1 in vibrissae

Project description:Mutations in TRPS1 cause trichorhinophalangeal syndrome types I and III, which are characterized by sparse scalp hair in addition to craniofacial and skeletal abnormalities. Trps1 is a vertebrate transcription factor containing nine zinc-finger domains, including a GATA-type zinc finger through which it binds DNA. Mice in which the GATA domain of Trps1 has been deleted (Trps1∆gt/∆gt) have a reduced number of pelage follicles and lack vibrissae follicles postnatally. To identify the transcriptional targets of Trps1 in the developing vibrissa follicle, we performed microarray hybridization analysis comparing expression patterns in the whisker pads of wild-type versus Trps1∆gt/∆gt embryos. We identified a number of transcription factors and Wnt inhibitors among transcripts downregulated in the mutant embryos, and several extracellular matrix proteins there were upregulated in the mutant samples. Whole whisker pads were dissected from E12.5 embryos and total RNA was isolated using the RNeasy Mini Kit (Qiagen). Triplicate RNA samples from three independent embryos of each genotype were amplified and labeled for hybridization to Affymetrix GeneChip MOE430A microarrays using Affymetrix reagents and protocols. The data output was analyzed using GeneSpring GX 10.0 commercial software (Agilent Technologies). P-values were calculated using an unpaired t-test. Expression values with a p-value less than or equal to 0.05 and a fold difference of at least 1.5 relative to wild-type baseline expression levels were considered significant.

Transcriptome profiling of radiation-transformed breast cells after TRPS1 siRNA knockdown.

Project description:TRPS1 was recently identified as a radiation marker in breast cancer. In order to characterise the molecular phenotype that is associated with TRPS1 we knocked out the gene in two radiation-transformed breast cell lines.

TRPS1 impairs myogenic differentiation in embryonal rhabdomyosarcoma [ChIP-seq]

Project description:We report here the analysis of TRPS1 chromatin binding by ChIP-Seq in embryonal rhabdomyosarcoma RD cells. We use here parental and TRPS1-KO RD cells. RD cells and RD-TRPS1-KO cells were cultured in growth medium and chromatin was prepared. TRPS1 DNA binding in RD cells and RD-TRPS1-KO cells using a selfmade antibody (referenced in Elster et al.) was determined by ChIP-seq.
