Project description:We used single cell RNA sequencing (scRNA-seq) to identify femur and tibia osteoblast cell stress response pathway to misfolding of type I procollagen with Gly610->Cys substitution in the triple helical region of alpha2(I) chain.
Project description:Gli1+ progenitors are considered as metaphyseal mesenchymal progenitors in the distal femur and proximal tibia under the growth plate. We used single cell RNA sequencing (scRNA-seq) to analyze the diversity of Gli1+ progenitors in response to methylprednisolone.
Project description:Affymetrix Chicken Gene 1.0 ST Array (ChiGene-1_1-st) profiles were generated from growth plate cartilage derived from the distal femur and proximal tibia of embryonic chickens at three developmental stages (day 12, 13 and 15) corresponding to stages prior to and immediately after the acqusition of mechano-responsive cartilage growth in the femur but not tibia (which does not respond to mechanical stimuli until later stages). Additionally, array profiles were generated from growth plate cartilage from the distal femur and proximal tibia of E15 chicks which were pharmacologically immobilized by decamethonium bromide treatment, which reduces longitudinal growth of the femur only at this stage.
Project description:Copy number variation profiles comparing control female Dehong chiken blood DNA with 11 different chicken breeds(Silkie, Tibetan Chicken, Gallus gallus spadiceus, Bearded Chicken, Jinhu Chicken, Anak Chicken, Beijing Fatty Chicken, Langshan Chicken, Qingyuan partridge Chicken, Shek-Ki Chicken, Wenchang Chicken) blood DNA. Each test breeds had one male and one female sample, totally 22 test DNA samples.Goal is to get the golbal copy number variation profile between chicken breeds.
Project description:Copy number variation profiles comparing control female Dehong chicken blood DNA with 3 different chicken breeds (white Leghorn, Cobb broiler, and Dou chicken) blood DNA. Each test breed had one male and one female sample, for a total of 6 test DNA samples. The goal is to determine the global copy number variation profiles between chicken breeds.

Project description:The chicken gastrointestinal tract (GIT) harbours a complex microbial community, involved in several physiological processes such as host immunomodulation and feed digestion. Other studies were already performed to define the chicken gut metagenome and its fecal metaproteome. For the first time, the present study analysed dietary effects on the protein inventory of the microbiota in crop and ceca of broilers. We performed quantitative label-free metaproteomics by using 1D-gel electrophoresis coupled with LC-MS/MS to identify the structural and functional changes triggered by diets supplied with varying amount of mineral phosphorus (P) and microbial phytase (MP). Phylogenetic assessment based on label-free quantification (LFQ) values of the proteins identified Lactobacillaceae as the major family in the crop section regardless of the diet, whereas proteins belonging to the family Veillonellaceae increased with the P supplementation. Within the ceca section, proteins of Bacteroidaceae were more abundant in the P-supplied diets, whereas proteins of Eubacteriaceae decreased with the P-addition. Proteins of the Ruminococcaceae increasedraised with the amount of MP while proteins of Lactobacillaceae werewas more abundant in the MP-lacking diets. Classification of the identified proteins into COGs and KEGG pathways underlined a diverse microbiota activity depending on the dietary regimen, indicating a thriving microbial community in the case of P and MP supplementation, and stressed microbial community when no P and MP were supplied. Insights oninto the identified KEGG pathways, as well as comparison between the GIT sections, dietary treatments, and the bacterial families encoding for the pathways of interest are provided.
