Discovery of novel and differentially expressed microRNAs between fetal and six month old skeletal muscle in goat

ABSTRACT: MicroRNAs (miRNAs) are small (∼22 nucleotides) noncoding ribonucleic acids (RNAs) that regulate gene expression by binding to their complementary sequences. Recent years, a great deal of miRNAs which highly-enriched in skeletal muscle have been identified, which can influence multiple facets of muscle development and function through their regulation of key genes controlling myogenesis. However, to date no miRNAs have been reported to modulate muscle development in goat. Total RNAs from the xuhuai goats longissimus thoracis at fetal and six month old stages were used to construct small RNA libraries for Solexa SBS technology sequencing. In the small RNA profile, a total of 15,627,457 clean reads were obtained from the fetal goat library and 15,593,721 clean reads from the six month old goat library. There are 471 conserved miRNAs overlapped in both libraries, of which 343 miRNAs were differential expressed. We identified 122 novel miRNAs in the fetal caprine library and 53 novel miRNAs in the six month old-caprine library.

Identify differentially expressed genes between two development stages in Xuhuai goat skeletal muscle through RNA-Sequencing

Project description:The goal of this study was to compare the transcriptome profiles (RNA-seq) of fetal and six month old goat in skeletal muscle. Total RNAs from the Chinese Xuhuai goat longissimus thoracis at fetal and six month old stages were used to construct cDNA libraries for Solexa SBS technology sequencing. After remove reads with adapters, reads in which unknown bases were more than 5% and low quality reads, we obtained 27,512,850 clean reads from the fetal caprine (FC) library and 27,582,908 clean reads from the six month old caprine (SMC) library. The total basepairs were 2,476,156,500 for FC and 2,482,461,720 for SMC. The ratio of clean reads mapped to reference genome was 45.43% for FC and 33.73% for SMC. The ratio of reads mapped to reference gene was 47.77% for FC and 34.03% for SMC. To reveal the molecular events during different development stages, genes that differentially expressed between the two libraries were identified. Clean reads that matched reference genes in each library were used to evaluate the expression level of transcripts. In total, 11663 genes were differentially expressed between the two development stages. There were 5134 genes with at least a two-fold difference in expression between FC and SMC libraries (FDR, 0.001), of which 1070 genes were up-regulated, 4064 were down-regulated in the six month old caprine compared to the fetal caprine muscle tissue, and 4911 were expressed in both library. Genes with less than one fold changes between FC and SMC libraries were excluded from further analysis. The results indicated that there were significant difference between the two development phase in gene-expression. In addition, some muscle related genes such as MyoD, Myf5, Myogenin, Mrf4, myosin heavy chain 3 (MYH3), Myoglobin and DLK1 were differentially expressed.

Differential expression and correlation analysis of miRNA–mRNA profiles in longissimus dorsi of different stage goats

Project description:MicroRNAs (miRNAs) are small non-coding RNAs that regulate the post transcriptional control of several pathway intermediates, and essential for regulation in skeletal muscle of many species, such as mice, cattle, pig and so on. However, a little number of miRNAs have been reported in the muscle development of goat. In this study, the longissimus dorsi transcripts of goat at 1- and 10-month-old were analyzed for RNA-seq and miRNA-seq. The results showed that 10-month-old Longlin goat expressed 327 up- and 419 down-regulated differentially expressed genes (DEGs) compared with the 1-month-old were founded. In addition, 20 co-up-regulated and 55 co-down-regulated miRNAs involved in muscle fiber hypertrophy of goat were identified in 10-month-old Longlin and Nubian goat compared with 1-month-old. Five miRNA–mRNA pairs (chi-let-7b-3p-MIRLET7A, chi-miR193b-3p-MMP14, chi-miR-355-5p-DGAT2, novel_128-LOC102178119, novel_140-SOD3) involved in the goat skeletal muscle development were identified by miRNA–mRNA negative correlation network analysis. Our results provided an insight into the functional roles of miRNAs of goat muscle-associated miRNAs, allowing us to better understand the transformation of miRNA roles during mammalian muscle development.

Deep Sequencing Analysis of miRNAs Expression in leg muscle of Xinghua Chicken

Project description:Purpose:We have used RNA-seq to examine of differentially expressed miRNAs in chicken leg muscle of three different development stages (11 embryo ages, 16 embryo ages, and 1 day old post hatch chick).The aims of this study are characterization of miRNAs differentially expressed in different developmental stage of chicken embryo, using RNA sequence sample. Methods: On this study we used two embryonic stage and one post hatch chick leg muscle of Xinghua chicken breed. Total RNA from E11 day embryo, E16 day embryo and 1 day post hatch chick was isolated by TRIzol following the manufacturer’s protocol (Invitrogen, CA, USA). Each stages were designed two samples, and the total samples were six (three group × two sample/group) and RNA samples of six individuals were pooled with equal amounts, and then were subjected to Illumina deep sequencing. Results: After eliminating adaptor and low-quality reads, a total of 5,302,700, 6,556,747, 5,359,793, 4,213,112, 7,112,885 and 7,469,939 clean reads were obtained in group E11 (E11.1-E11.2), group E16 (E16.1-E16.2) and group P1 (P1.1–P1.2) libraries, respectively. The clean reads were aligned to the chicken genome databases, miRBase, Rfam, RepBase and mRNA. Conclusions:To assess miRNA expression during chicken embryo skeletal muscle development, we sequenced and analyzed leg muscle at 11 day embryo age, 16 day embryo age, and 1 days post hatch.

Small RNA sequencing Analysis of muscle and adipose in Chinese swamp buffalo

Project description:Background: Intramuscular fat (IMF) content is an important index for beef quality. However, the genetics of IMF deposition is complex and still largely unclear, especially in buffalo. To identify miRNAs with potential regulatory role in lipid accumulated in muscle, we performed small RNA sequencing and identified miRNAs expressed in the longissimus dorsi muscle and back fat of Chinese buffalo, which provided vital information for further identification of miRNAs with potential regulatory role in the lipid accumulated in muscle. Results: Six small RNA libraries were constructed. A total of 66,128,645 and 70,974,347 raw reads were obtained from muscle and adipose groups, respectively. After filtering the adaptor and low quality reads, 60,765,257 and 67,327,095 clean reads were retained. In total, 721 miRNAs were identified.

Identification of reproductive performance-related genes in the bovine hypothalamus and pituitary gland and analysis of the regulatory network

Project description:We explored the gene expression patterns of the pituitary gland and hypothalamus of Angus cows at different growth and developmental stages by deep sequencing the transcriptome and identified genes that affect bovine reproductive performance to provide new ideas for improving bovine fertility in production practice. We selected three 6-month-old (weaning period), three 18-month-old (first mating period) and three 30-month-old (early postpartum) Angus cows. The physiological statuses of the cows in each group were the same, and their body shapes were similar. After quality control of the sequencing, the transcriptome analyses of 18 samples yielded 129.18 GB of clean data. Clean data for each sample reached 6.30 GB. The GC content was >47.61%, and the base percentage of Q30 was at least 94.19%. We detected 13280 and 13318 expressed genes in the pituitary gland and hypothalamus, respectively, and screened 35 and 50 differential genes for each, respectively. Differential genes in both tissues were mainly concentrated in metabolism, lipid synthesis, and immune-related pathways in the 18-month-old cows compared with those in the 6-month-old cows. The 30-month-old cows presented more regulated reproductive behavior, and pituitary CAMK4 was the main factor regulating the reproductive behavior during this period via the pathways for calcium signaling, longevity, oxytocin, and aldosterone synthesis and secretion.

A comprehensive microRNA expression profile related to hypoxic adaptation in Tibetan pig

Project description:In this study, miRNA-seq technique was used to identify differentially expressed miRNAs (DE miRNAs) in cardiac muscle of the Tibetan pig (TP) and Yorkshire pig (YP), which were both raised in highland environments. We obtained 108 M clean reads and 372 unique miRNAs that included 210 known pre-miRNAs and 162 novel pre-miRNAs. In addition, 20 DE miRNAs, including 10 upregulated and 10 downregulated miRNAs, were identified by comparing TP and YP. Based on the expression abundance and differentiation between the two populations, we predicted their targets, and KEGG pathway analyses suggested that DE miRNAs between the Tibetan pigs and Yorkshire pigs are involved in hypoxia-related pathways, such as the MAPK, mTOR, and VEGF signaling pathways, cancer-related signaling pathways, etc. Five DE miRNAs were randomly selected to validate the veracity of miRNA-seq using real-time PCR. The results showed that the expression corresponds to the trend in miRNA-seq, hence the deep-sequencing methods were feasible and efficient. This study expanded the number of hypoxic-adaptation-related miRNAs in pig and indicated that the expression patterns of hypoxia-related miRNAs are significantly altered in the Tibetan pig. DE miRNAs may play important roles in hypoxic adaptation after migration to hypoxic environments. mRNA profiles of 6-month old Tibetan pig (TP) and Yorkshire pig (YP) were generated by deep sequencing, in duplicate, using Hiseq 2000.
