AbstractIn order to detect the molecular mechanism of heterosis in pigs, an mRNA differential display (DD) technique was performed to investigate the differences in gene expression in the longissimus dorsi muscle tissues from Meishan, Meishan×Large White cross and Large White pigs. Fourteen expressed sequence tags (ESTs), differentially expressed between the hybrid and purebred pigs, were isolated and identified through semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR). Nucleotide sequence analysis revealed that the 14 ESTs are not homologous to any of the known genes or ESTs. These novel ESTs were then deposited in the GenBank database. Tissue expression profile analysis showed that the ESTs were expressed in most tissues, including heart, spleen, liver, kidney, small intestine, ovary and lung, and this also implied that these genes must be important for the life process. Our results indicate the diversity of differential display of genes between the hybrids and purebreds in the Meishan×Large White cross combination. Results also suggest that heterosis in pigs might be derived from the differential expression of many indispensable genes in specific life phases.

To explore the differentially expressed mRNAs between oxidative and glycolytic muscles, Qianbei black pigs were slaughtered and longissimus dorsi muscle (LDM) and psoas major muscle (PMM) were selected and sequenced using Illumina Hiseq TM 4000. Bioinformatics analysis and differentially expressed genes were analyzed by GO and KEGG. qRT-PCR was used to validate the RNA-seq result. As a result, 69 differentially expressed genes were identified, with 46 down regulated genes and 23 up regulated genes in LDM versus PMM, which were categorized into 44 functional groups under three GO classifications. KEGG pathway analysis revealed 20 pathways were enriched. qRT-PCR shows the expression trends of ND6, MYH7, TBX1, FOS and SLC7A5 are consist with the RNA-seq result. We speculated these five genes may involve in differentiation of muscle cells, metabolism of carbohydrate and lipid, deposits of intramuscular fat and transformation of different types of muscle fibers.

Abstract The mRNA differential display technique was performed to investigate the differences in gene expression in the Longissimus dorsi muscle tissues from Landrace×Large White cross-combination. One novel gene that was differentially expressed was identified using semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) and its complete cDNA sequence was obtained using the rapid amplification of cDNA ends (RACE) method. The nucleotide sequence of the gene is not homologous to any of the known porcine genes. The sequence prediction analysis revealed that the open reading frame of this gene encodes a protein of 260 amino acids that contains the putative conserved domain of the carbonic anhydrase, and this protein has high homology with the carbonic anhydrase III (CA-III) of four species-mouse (91%), horse (91%), rat (89%) and human (86%)–so that it can be defined as swine carbonic anhydrase III. The phylogenetic tree analysis revealed that the swine CA-III has a closer genetic relationship with the horse CA-III than with those of mouse, rat and human. The tissue expression analysis indicated that the swine CA-III gene is generally expressed in most tissues. Our experiment is the first to establish the primary foundation for further research on the swine CA-III gene.

Circular RNA (circRNA) and long non-coding RNA (lncRNA) are known to participate in adipogenesis and myogenic differentiation, but their impact on porcine muscle traits is not well understood. We compared their expressional profiles in the longissimus dorsi muscle of Chinese Huainan pigs (HN, the fat type) and Western commercial Duroc×(Landrace×Yorkshire) (DLY, the thin type) pigs, and 854 mRNAs, 233 lncRNAs, and 66 circRNAs (p < 0.05 and ｜log2FoldChange｜>1) were found to be differentially expressed. The differentially expressed mRNA and circRNA parental genes were enriched in the Wnt signaling pathway (adipogenesis), the transition between fast and slow fibers (myogenic differentiation), and alanine, aspartate and glutamate metabolism (pork flavor). The potential lncRNAs/circRNAs-miRNAs-mRNAs regulatory networks shared MYOD1, PPARD, miR-423-5p and miR-874, which were associated with skeletal muscle muscular proliferation, differentiation/regeneration and adipogenesis. Taken together, these differentially expressed non-coding RNAs may be involved in the molecular basis of muscle traits, acting as the competing endogenous RNA (ceRNA) for miRNAs.
