Project description:Dongxiang blue-shelled chicken, an indigenous chicken breed in China, has segregated significantly for the dermal hyperpigmentation phenotype. Two lines of the chicken have been divergently selected with respect to comb color for over 20 generations. The recent selection has also resulted in a significant difference in egg production. The red comb line (RCL) chicken produces significantly higher number of eggs than that by the dark comb line (DCL) chicken. The objective of this study was to explore potential mechanisms involved in the relationship between comb color and egg production among chickens. We performed genome-wide association study to identify candidate genes associated with chicken comb color using SNP array data, and we conducted selective sweep analysis to identify putative regions of selection harboring pleiotropic genes affecting both comb color and egg production.

Project description:Here, we report on a novel chicken comb phenotype, designated Antler-comb. Using a 600K Axiom® Genome-Wide Chicken Genotyping Array, we separately genotyped 12 and 24 female Hetian Wildtype-comb and Antler-comb chickens, respectively. Meanwhile, we sequenced the genomes of 10 Hetian Antler-comb and 10 Wildtype-comb chickens to interrogate the GWAS results and explore the potential genetic variants underlying this phenotype. After conducting a genome-wide association study (GWAS), a 36.5-kb candidate genomic region (chromosome 19:757,754-794,200) related to the Antler-comb phenotype was identified, which wholly and partially encompassed heat shock factor 5 (HSF5) and ring finger protein 43 (RNF43), respectively. HSF5 was ectopically expressed and RNF43 was up-regulated in Antler-comb chickens at embryo ages 7 and 9 (E7 and E9). We further genotyped the most significant single-nucleotide polymorphism (SNP) site, Chr19:794200, across 222 chickens of 16 breeds. We found that the major allele G in Antler-comb chickens remained highly significant across different breeds, and each Antler-comb chicken harbored an allele G. Whole-genome re-sequencing (WGS) involving 10 Hetian Antler-comb and 10 Wildtype-comb chickens reaffirmed the 36.5-kb candidate genomic region, and revealed a genomic duplication, which was 15.7 kb in length and pertained to the 5’-untranslated region and 5’-flanking region of HSF5 (Chr19:784,335-800,034), suggesting its possible role in inducing ectopic expression of HSF5 and altering expression of RNF43 during comb development (E7 and E9). The present study furthers our understanding of this novel chicken comb phenotype, and likely gives another example regarding interactions between genetic variation and phenotype.

Project description:Multipotent C3H10T1/2 cells can be induced to differentiate into mature brown adipocytes by 3-days BMP7 pretreatment followed by standard adipogenic induction. In this study, we used microRNA array to identify the microRNAs that were regulated by 3-days BMP7 treatment in C3H10T1/2 cells. One BMP7-treated sample and one vehicle-treated sample were used in this study to obtain the fold expression of microRNAs between BMP7 vs vehicle.

Project description:To gain understanding in the tissue engineering of a human auricle, neocartilages generated from microtia and normal surgical remnants were compared by microarray anlaysis. Comparison of these two groups after 10 weeks development in vivo (nude mouse) revealed no statistically significant differences Comparison of normal and microtia cells, each seeded on nanoPGA and supplemented with BMP7 in a slow-release hydrogel, showed statistically significant differences in certain genes identified by microarray analysis. Such differences were also noted in several analyses comparing counterpart seeded cells without BMP7. Normal cells with and without growth factor showed several transcription and proliferative genes upregulated with addition of BMP7. Microtia with added BMP7 compared to normal neocartilage with added BMP7 was statistically significantly increased in gene levels of homeobox A10, DEAD box polypeptide 17, and arginine vasopressin.

Project description:Bone morphogenetic proteins (BMPs) are members of the TGF-β superfamily of growth factors. They are known for their roles in regulation of osteogenesis and developmental processes and, in recent years, evidence has accumulated of their crucial functions in tumor biology. BMP7, in particular, has been implicated in breast cancer. However, little is known about BMP target genes in the context of tumor. We therefore explored the effects of BMP7 treatment on global gene transcription in five breast cancer cell lines during a 6-point time series. Data analysis included hierarchical clustering of differentially expressed genes, gene ontology enrichment analyses and model based clustering of temporal data. BMP7 had a strong effect on gene expression. The cellular functions most strongly affected were regulation of transcription and development. The observed transcriptional response followed a temporal sequence. Hierarchical clustering revealed distinct differences in the response of individual cell lines to BMP7, but also highlighted a synexpression group of genes. Finally, this study provides a list of potential novel BMP target genes relevant in breast cancer.

Project description:In this study, RNA sequencing (RNA-seq) was employed to compare the whole transcriptomic differences between six Partridge Shank chickens that are divergent in comb sizes and divided into two groups. A total of 563 differentially expressed genes (DEGs) were found in the two groups. Among these DGEs, 277 were up-regulated and 286 were down-regulated in the big comb group. According to the animal QTL database, eight DEGs including BMP2 and CHADL matched the QTLs associated with the chicken comb traits. Functional annotation analysis revealed that the DEGs were involved in cell communication and calcium signaling. Protein-protein interaction network analysis showed that STK32A, PI3KR1, EDN1, HSPA5 and HSPA8 might have great impact on comb growth. Moreover, potential alternative splicing (AS) events and single nucleotide polymorphisms (SNP) were also identified.
