Project description:Hoxc13 has been shown to be essential for proper hair shaft differentiation as Hoxc13 gene-targeted (Hoxc13tm1Mrc) mice completely lack external hair. Because of the phenotypic parallels to the Foxn1nu (nude) mutant mice, we tested whether Hoxc13 and Foxn1 act in a common pathway of hair follicle (HF) differentiation. We show that the alopecia exhibited by both the Hoxc13tm1Mrc and Foxn1nu mice is due to strikingly similar defects in hair shaft differentiation and that both mutants suffer from a severe nail dystrophy. These similarities are consistent with the overlap of Hoxc13 and Foxn1 expression patterns in the HF and nail matrix. DNA microarray analysis of scapular skin from Hoxc13tm1Mrc mutant (mut) compared to wild type (wt) mice identified Foxn1 as significantly down-regulated along with numerous hair keratin genes. This Foxn1 down-regulation apparently reflects the loss of direct transcriptional control by HOXC13 as indicated by our results obtained through co-tranfection and chromatin immunoprecipitation (ChIP) assays. Total number of samples was 6. The experiment was perfomed in triplicate involving 3 indendent wild type skin samples (sample 1, 2, and 3) and 3 independent mutant skin samples (sample 4, 5, and 6).

Project description:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.

Project description:Purpose: To study the alteration of whole transcriptome of Lewis lung carcinoma (LLC) cells after the decreasing of malignant properties of tumor by treatment of tumor-bearing mice with RNase A. Methods: Whole transcriptome profile of Lewis lung carcinoma before and after RNase A treatment were generated by deep sequencing using SOLiD 5.5. The sequence reads were mapped by Bioscope 1.3 software, differential expression was evaluated by Cufflinks v.2.0.1 package. Results: Difference in expression was found for 966 genes. Conclusions: Our study represents the first detailed analysis of alteration of transcriptome of Lewis lung carcinoma after the decrease of malignant prtoperties of the tumor (proliferation and invasion) by RNase A.
