Project description:Ramie fibers extracted from the stem barks have been utilized for thousands years in China, and its biosynthetic mechanism is poorly understood. Here, we have characterized and compared the expression profiling of the barks from the top and middle part of stem where the secondary cellular walls (SCWs) of fiber cell have not initiated growth and was thickening, respectively; resulting in 4,520 differential expression (DE) protein-coding transcripts (PCTs), 1,287 DE long noncoding RNAs (lncRNAs), 88 DE miRNAs and 78 DE circular RNAs (circRNAs). Among the 4,520 DE PCTs, 75 were identified to be the homolog of the Arabidopsis SCW-biosynthetic genes. Overexpression of whole_GLEAN_10014861 (a homolog of SND1) in Arabidopsis caused a significant up-regulation in the expression of AtMYB46 and AtMYB83 that are two key regulators for SCW biosynthesis, thus conferring more fiber cells, along with a remarkable thickening in the SCWs of these cells. Bioinformatic prediction revealed 14 of the 75 homolog targeted by 16 noncoding RNAs (including 8 miRNAs and 8 lncRNAs), and two involved in the competing endogenous RNAs networks, indicating a complex regulatory network for the SCW biosynthesis of bast fiber in ramie. This study provides important insights into the bast fiber biosynthesis of ramie.

Project description:According to a previous study on the microscopic examination of stem barks in ramie, bast fibers from different parts of stem bark showed distinct differences at the developmental level: specifically, the barks in the top part of stem (TPS) did not initiate fiber growth, whereas barks in the middle part of stem (MPS) had a large number of fibers with thickening secondary walls. We have performed the phosphoproteome analysis for the tissues of TPS and MPS, and then carried out the comparison of phosphorylation level of proteins between two tissues, thereby to identified differentially phosphorylated proteins. These datasets represent the raw UHPLC spectra for phosphoproteome of ramie TPS and MPS.

Project description:Skeletal muscles are composed of a heterogeneous collection of fiber types with different physiological adaption in response to a stimulus and disease-related conditions. Each fiber has a specific molecular expression of myosin heavy chain molecules (MyHC). So far MyHCs are currently the best marker proteins for characterization of individual fiber types and several proteome profiling studies have helped to dissect the molecular signature of whole muscles and individual fibers. Herein, we describe a mass spectrometric workflow to measure skeletal muscle fiber type-specific proteomes. To bypass the limited quantities of protein in single fibers, we developed a Proteomics high-throughput Fiber Typing (ProFiT) approach enabling profiling of MyHC in single fibers. Aliquots of protein extracts from separated muscle fibers were subjected to capillary LC-MS gradients to profile MyHC isoforms in a 96-well format. Muscle fibers with the same MyHC protein expression were pooled and subjected to proteomic, pulsed-SILAC and phosphoproteomic analysis. Our fiber type-specific quantitative proteome analysis confirmed the distribution of fiber types in the soleus muscle, substantiates metabolic adaptions in oxidative and glycolytic fibers, and highlighted significant differences between the proteomes of type IIb fibers from different muscle groups, including a differential expression of desmin and actinin-3. A detailed map of the Lys-6 incorporation rates in muscle fibers showed an increased turnover of slow fibers compared to fast fibers. In addition, labeling of mitochondrial respiratory chain complexes revealed a broad range of Lys-6 incorporation rates, depending on the localization of the subunits within distinct complexes.

Project description:To evaluate the biological effects at the transcriptional level of manufactured nanomaterials, whole genome microarrays of rat alveolar macrophages (NR8383) exposed to three types of submicron-diameter carbon fibers (SCFs) with different physicochemical properties were performed. In comparison with the fibers of SCF1, the fibers of SCF2 were shorter, and the fibers of SCF3 were thinner.

Project description:Transcriptome analysis of root development related genes in terrestrial and hydroponic ramie. Ramie seedlings were cultivated in soil, and in hydroponic with the shoot-cutting propagation method. The root samples from hydrophonic ramie were collected from the early stage (5-day-old seedling) and the late stage (30-day-old seedling) of acquatic roots induction. The roots of ramie seedling cultivated in soil were also collected for comparative analysis. Our study represents the detailed analysis of ramie root transcriptomes with biologic replicates.
