Selection of cashmere fineness functional genes by translatomics

ABSTRACT: Cashmere fineness is an important index to evaluate cashmere quality. Liaoning Cashmere Goat (LCG) has a large cashmere production and long cashmere fiber. But the fineness is not enough,improving the fineness of cashmere is an important problem.Therefore, it is important to find genes involved in cashmere fineness that can be used in future in future endeavors aiming to improve this phenotype. With the continuous advancement of research, the regulation of cashmere fineness has made new development through high-throughput sequencing and genome-wide association analysis. It has been found that translatomics can identify genes associated with phenotypic traits. Through a translatomic analysis, the skin tissue of LCG sample groups differing in cashmere fineness was sequenced by Ribo-seq. With this data, we identified 529 differentially expressed genes between the sample groups among the 27197 expressed genes(expressed,not co-expressed). From these, 343 genes were up-regulated in the fine LCG group in relation to the coarse LCG group and 186 down-regulated in the same relationship.Through GO enrichment analysis and KEGG enrichment analysis of differential genes, the biological functions and pathways of differential genes can be found. In the GO enrichment analysis, 491 genes were significantly enriched, and the functional region was mainly in the extracellular region. In the KEGG enrichment analysis, the enrichment of human papillomavirus infection pathway was the most. We found that COL6A5 gene may affect cashmere fineness. The characteristics and expression analysis of COL6A5 gene may play an important role in the study of LCG cashmere fineness.

Project description:OBJECTIVE: To investigate the differentially expressed genes related to the chemosensitivity of laryngeal squamous cell carcinoma ï¼LSCCï¼by microarrays arrays. METHODS: 1. A total number of 11 patients who underwent induction chemotherapy for primary hypopharyngeal squamous cell carcinoma (7 patients are sensitive to chemotherapy ,and others are not) were recruited for microarray and miRNA array gene expression analysis 2. Bioinformatics analysis of differentially expressed genes screened by microarrays : The differential gene cluster analysis was applied in biological processes, cellular components and molecular functions by GO database; The differential gene enrichment analysis was applied in signaling pathways by KEGG database, and the differentially expressed and biologically meaningful core genes would be screened. RESULTS: 1. Analyzed by microarrays, there were 1554 genes significantly related to the sensitivity to chemotherapy; Among these 1554genes, 777 showed a higher expression in the tissue from patients who are sensitive to chemotherapy , while 785 presented the contrasting pattern. CONCLUSIONS: The research revealed a gene expression signature of chemosensitivity in laryngeal squamous cell carcinoma by microarrays arrays. The result will contribute to the understanding of the molecular basis of laryngeal squamous cell carcinoma and help to improve diagnosis and treatment. 1.
