A novel porcine gene, LIPC, differentially expressed in the liver tissues from Meishan and Large White pigs. J Appl Genet 2011; 52:219-23. [PMID: 21327595 DOI: 10.1007/s13353-011-0032-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2010] [Revised: 01/14/2011] [Accepted: 01/19/2011] [Indexed: 10/18/2022]
Abstract
The mRNA differential display technique was performed to investigate the differences in gene expression in the liver tissues from Meishan and Large White pigs. One novel gene that was differentially expressed was identified through semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR) and the cDNA complete sequence was then 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 encoding a protein of 501 amino acids has high homology with the lipase, hepatic (LIPC) of seven species--cattle (82%), rhesus monkey (79%), chimpanzee (78%), rabbit (77%), human (78%), mouse (73%) and rat (72%)--so that it can be defined as the swine LIPC gene. Phylogenetic analysis revealed that the swine LIPC gene has a closer genetic relationship with the LIPC of cattle. Tissue expression profile analysis indicated that the swine LIPC gene is also differentially expressed in other detected tissues from Meishan and Large White pigs. Our experiment suggested that the swine LIPC gene might play an important role in the superabundant fat deposition of Chinese pigs.

Abstract
The complete coding sequences of three of Black-boned sheep (Ovis aries) genes Sfxn1, Snai2 and Cno were amplified using the reverse transcriptase polymerase chain reaction (RT-PCR) according to the conserved sequence information of the cattle or other mammals and known highly homologous sheep ESTs. Black-boned sheep Sfxn1 gene encodes a protein of 322 amino acids which has high homology with the Sfxn1 proteins of five species--cattle 98%, pig 95%, human 95%, rat 93%, and mouse 93%. Black-boned sheep Snai2 gene encodes a protein of 268 amino acids that has high identity with the Snai2 proteins of six species--cattle 99%, pig 94%, human 93%, dog 93%, rat 91%, and mouse 90%. Black-boned sheep Cno gene encodes a protein of 214 amino acids that has high homology with the Cno proteins of four species--cattle 97%, human 75%, mouse 67%, and rat 65%. The phylogenetic tree analysis demonstrated that Black-boned sheep Sfxn1, Snai2 and Cno proteins have close relationship with cattle Sfxn1, Snai2 and Cno proteins. The tissue expression analysis indicated that Black-boned sheep Sfxn1, Snai2 and Cno genes were expressed in a range of tissues including leg muscle, kidney, skin, longissimus dorsi muscle, spleen, heart and liver. Our experiment is the first to provide the primary foundation for further insight into these three sheep genes.

Abstract
Differences in gene expression in muscles from Chinese black-boned sheep and local common sheep were investigated using mRNA differential display. One differentially expressed novel gene was identified through semi-quantitative RT-PCR, and the full-length cDNA sequence was then obtained using the rapid amplification of cDNA ends (RACE). The nucleotide sequence of this gene is not homologous to any of the known sheep genes, but it contains an open reading frame encoding a protein of 416 amino acids, which has high homology with matrix metallopeptidase 7 (matrilysin, uterine) (MMP7) of 10 species: bovine (93%), rhesus monkey (75%), human (74%), pig (73%), chimpanzee (73%), dog (73%), horse (72%), mouse (66%), rat (65%), and chicken (53%). Thus the novel gene can be defined as the sheep MMP7 gene. It was finally assigned to GeneID:100192317. The phylogenetic tree analysis revealed that the sheep MMP7 gene is closely related to the bovine MMP7. Our experiment is the first one to establish the primary foundation for further research on the sheep MMP7 gene.

Abstract
The complete coding sequences of three of sheep genes SLC25A4, SLC25A5 and SLC25A6 were firstly amplified using the reverse transcriptase polymerase chain reaction (RT-PCR) according to the conserved sequence information of the cattle or other mammals and known highly homologous sheep ESTs. Sheep SLC25A4, SLC25A5 and SLC25A6 genes encode three corresponding proteins of 298 amino acids which contain the identically conserved putative mitochondrial carrier protein domain. Sheep SLC25A4 protein has high homology with the SLC25A4 proteins of six species-cattle (99%), human (95%), rat (95%), mouse (94%), dog (94%) and chicken (89%). Sheep SLC25A5 protein has high identity with the SLC25A5 proteins of five species-cattle (100%), dog (99%), mouse (98%), rat (98%) and human (98%). Sheep SLC25A6 protein also has high homology with the SLC25A6 proteins of four species-cattle (99%), human (97%), pig (97%) and chicken (93%). The phylogenetic tree analysis demonstrated that sheep SLC25A4, SLC25A5 and SLC25A6 proteins share a common ancestor. Moreover, SLC25A4, SLC25A5 and SLC25A6 proteins present stronger interaction each other. The tissue expression analysis indicated that sheep SLC25A4, SLC25A5 and SLC25A6 genes were expressed in a range of tissues including leg muscle, kidney, skin, longissimus dorsi muscle, spleen, heart and liver. Our experiment is the first to provide the primary foundation for further insight into these three sheep genes.

Abstract
The messenger RNA differential display technique was performed to investigate the differences of gene expression in the liver tissues from Meishan and Large White pigs. A fragment of one differentially expressed gene was isolated and sequenced. A complete complementary DNA (cDNA) sequence was obtained using the rapid amplification of cDNA end method. 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 339 amino acids which have high homology with those of the ER lipid-raft-associated 2 isoform 2 (ERLIN2) of eight species--human (97%), rhesus monkey (97%), rat (96%), horse (97%), cattle (97%), mouse (97%), dog (95%), and red jungle fowl (90%)--so that it can be defined as the swine erlin2 gene. The phylogenetic tree analysis revealed that the swine erlin2 gene has a closer genetic relationship with the erlin2 genes of human and rhesus monkey. The tissue expression profile analysis indicated that the swine erlin2 gene is differentially expressed in detected tissues from Meishan and Large White pigs. Our experiment suggested that the swine erlin2 gene might play an important role in the superabundant fat deposition of Chinese pigs.

Abstract
The glutathione S-transferase mu 2 gene (GSTM2) encodes a GST functioning in the elimination of electrophilic compounds and the regulation of cell growth. In this study, the sequence of porcine GSTM2 gene that contains the complete sequence encoding a protein of 218 amino acids was cloned. The deduced amino acid sequence shared 76%, 78% and 76% identity with that of human, mouse and rat, respectively. mRNA expression analysis showed that the porcine GSTM2 gene was expressed at a high level in liver and testis, at a medium level in longissimus dorsi muscle, adipose tissue, spleen and lung, at a low level in kidney, and at a very low level in heart and embryo. A nonsense mutation (CGA-->TGA) resulted from C27T substitution in the fifth exon to produce a premature translation termination codon was identified, and it was discovered that nonsense-mediated mRNA decay might have an effect on the regulation of porcine GSTM2 gene expression. This polymorphism was analyzed in Large White, Landrace, Meishan and Qingping pig populations using the Taq I-polymerase chain reaction-restriction fragment length polymorphism method. The result showed that allele C had a higher frequency than allele T in each population.

Abstract
In order to detect the molecular basis of heterosis in pigs, suppression subtractive hybridization was carried out to investigate the difference in gene expression in the Longissimus dorsi muscle tissues between MeishanxYorkshire F1 crossbreeds and their parents, Meishan pigs. The swine myosin regulatory light chain 2 (MRLC2) gene differentially expressed between the crossbreeds and the purebreds was isolated and identified using semi-quantitative reverse transcriptase polymerase chain reaction and its complete cDNA sequence was obtained using the rapid amplification of cDNA ends method. The nucleotide sequence of the gene is not homologous to any of the known porcine genes. The sequence prediction analysis reveals that the open reading frame of this gene encodes a protein of 172 amino acids containing the putative conserved domain of the EF-hand superfamily. This predicted amino acid sequence of porcine MRLC2 protein exhibits 99%, 98%, 98%, 98% and 97% identity with that of cattle, human, dog, rat and mouse, respectively. The homology analysis revealed that the MRLC2 protein was very much conserved in evolution. The tissue expression analysis indicated that the swine MRLC2 gene is highly expressed in muscle, fat, heart, liver, spleen, lung, kidney, stomach, small intestine, ovary and testis, but not expressed in pancreas.

Abstract
In order to investigate porcine heterosis on the molecular basis, Large White (L), a European purebred, and Meishan (M), a Chinese indigenous purebred, were hybridized directly and reciprocally to produce F1 hybrids, Large WhitexMeishan (LM) and MeishanxLarge White (ML) pigs. Using mRNA differential display, we found an expression sequence tag (EST) differentially expressed in F1 hybrids and their parents, designated as EST55, which was homologous to human and murine skeletal muscle protein (SMPX), and the full-length cDNA of porcine SMPX was cloned by the rapid amplification of cDNA end (RACE) method. Translation of the mRNA transcript revealed an open reading frame (ORF) of 86 amino acid residues encoding a nuclear location signal peptide, two overlapping casein kinase II phosphorylation sites and one N-glycosylation site with theoretical molecular weight of 9.3 kDa. Alignment analysis revealed that the deduced protein sequence shared 94%, 83% and 78% homology with that of its human, mouse and rat counterparts, respectively. Reverse transcription-polymerase chain reaction (RT-PCR) analysis showed that it was expressed predominantly in skeletal and heart muscles, whereas at a moderate level in backfat, spleen, stomach and uterus tissues. Two single nucleotide polymorphism (SNPs), located in 5'- and 3'-untranslated region (UTR), respectively,were identified by PCR and sequencing. Phylogenetic tree and the secondary structure prediction were also performed. The possible relationship between porcine SMPX and heterosis was discussed.

Abstract
To identify genes associated with morphological phenotypes of human bladder transitional cell carcinoma, we used suppression subtractive hybridization (SSH) to create a subtractive cDNA library of two established cell lines, BLZ-211 and BLS-211, derived from a patient with transitional cell carcinoma of the bladder, then to screen for differentially expressed genes. Real-time reverse transcription-polymerase chain reaction was used to further confirm the selected differentially expressed genes. Forward and reverse subtractive cDNA libraries yielded 168 and 305 putative clones, and among them more than 90% contained the inserts. After differential screening, 36 different transcripts were obtained from 64 cDNA clones of a forward and reverse subtraction library. Among them, 17 were identified as known genes by homology, for example, Vimentin, Keratin7, DDH and UCH-L1. The remaining 19 were unknown expressed genes, and were collected as new expressed sequence tags by the GenBank dbEST database. Their function will be studied further. Thus, SSH appears to be a useful technique for identifying differentially expressed genes between cell lines or clones. Our results, as revealed by SSH, also suggest that differences in gene expression of cytoskeletal proteins might contribute to the different morphologies in BLZ-211 and BLS-211 cells.

Abstract
To study the molecular basis of heterosis, suppression subtractive hybridization was used to investigate the differences in gene expression between porcine Longissimus dorsi of F1 hybrids Large WhitexMeishan and their female parents Meishan. From two specific subtractive cDNA libraries, the clones selected by reverse Northern high-density blot screening were chosen to clone full-length cDNA by rapid amplification of cDNA ends. An expression-upregulated gene for Meishan skeletal muscle, designated protein phosphatase 1, catalytic subunit, beta isoform (PPP1CB), was identified. Porcine PPP1CB contains an open reading frame encoding 327 amino acid residues with 13 and 1763 nucleotides in the 5' and 3' untranslated regions, respectively. A DNA fragment of 721 nucleotides was amplified and a mutation that creates/disrupts a restriction site for endonuclease RsaI was found. The derived amino acid sequence of PPP1CB has high homology with the PPP1CB of three species, Mus musculus (99%), human (99%) and mouse (100%). The tissue expression analysis indicated that the swine PPP1CB gene is generally expressed in most tissues. The possible role of PPP1CB and its relation to porcine heterosis are discussed.

Abstract
LIM domain proteins are important regulators in cell growth, cell fate determination, cell differentiation and remodeling of the cell cytoskeleton by their interaction with various structural proteins, kinases and transcriptional regulators. Using molecular biology combined with in silico cloning, we have cloned the complete coding sequence of pig LIM and the cysteine-rich domain 1 gene (LMCD1) which encodes a 363 amino acid protein. The estimated molecular weight of the LMCD1 protein is 40,788 Da with a pI of 8.39. It was found to be highly expressed in both skeletal muscle and cardiac muscle. Alignment analysis revealed that the deduced protein sequence shares 86%, 91% and 93% homology with that of its human, mouse and rat counterparts, respectively. The LMCD1 protein was predicted by bioinformatics software to contain a novel cysteine-rich domain in the N-terminal region, two LIM domains in the C-terminal region, nine potential protein kinase C phosphorylation sites, seven casein kinase II phosphorylation sites, a tyrosine kinase phosphorylation site, seven N-glycosylation and N-myristoylation sites and a single potential N-glycosylation site, which is similar to the protein's human counterpart. Phylogenetic tree was constructed by aligning the amino acid sequences of the LIM domain from different species. In addition, four base mutations were detected by comparing the sequences of Large White pigs with those of Chinese Meishan pigs. The G294A mutation site was confirmed by polymerase chain reaction-single-strand conformation polymorphism analysis. Its allele frequencies were studied in five pig breeds.
