M. M. Li, Geng, J., Guo, Y. J., Jiao, X. Q., Lu, W. F., Zhu, H. S., Wang, Y. Y., and Yang, G. Y., Cloning and prokaryotic expression of the porcine lipasin gene, vol. 14, pp. 14698-14705, 2015.

Lipasin has recently been demonstrated to be involved in lipid metabolism. In this study, two specific primers were used to amplify the lipasin open reading frame from porcine liver tissue. The polymerase chain reaction product was cloned to a pGEM®-T Easy Vector, digested by SalI and NotI, and sequenced. The lipasin fragment was then cloned to a pET21(b) vector and digested by the same restriction enzyme. The recombinant plasmid was transferred to Escherichia coli (BL21), and the lipasin protein was induced with isopropyl-β-D-thiogalactopyranoside.

Expression and localization of cFLIP anti-apoptotic protein in the porcine corpus luteum and corpora albicans during the estrous cycle and pregnancy

H. Z. Jin, Shi, W. S., Tian, Y., Liu, Y., Jin, Y., and Manabe, N., Expression and localization of cFLIP anti-apoptotic protein in the porcine corpus luteum and corpora albicans during the estrous cycle and pregnancy, vol. 14, pp. 8262-8272, 2015.

We determined expression and localization of the anti-apoptotic cellular FLICE inhibitory protein (cFLIP) in the porcine corpora lutea (CL) and corpus albicans (CA) during estrous and preg­nancy. The CL and CA were collected at different stages of estrous to determine cFLIP immunolocalization, and mRNA and protein ex­pression.

Identification of BPI protein produced in different expression system and its association with Escherichia coli F18 susceptibility

Z. C. Wu, Liu, Y., Dong, W. H., Sun, S. Y., Zhu, G. Q., Wu, S. L., and Bao, W. B., Identification of BPI protein produced in different expression system and its association with Escherichia coli F18 susceptibility, vol. 14, pp. 1111-1123, 2015.

The super antibiotic bactericidal/permeability-increasing (BPI) protein is a member of a new generation of proteins that have been implicated as endotoxin-neutralizing agents. In this study, recom­binant porcine BPI protein was obtained by generating porcine BPI encoding prokaryotic, eukaryotic, and yeast expression vectors. Recombinant protein expression was detected in yeast GS115, Escherichia coli, and 293-6E cells by gel electrophoresis and Western blotting.

Functional characterization of genetic variants in the porcine TLR3 gene

L. Wang, Chen, Y. C., Zhang, D. J., Li, H. T., Liu, D., and Yang, X. Q., Functional characterization of genetic variants in the porcine TLR3 gene, vol. 13, pp. 1348-1357, 2014.

Toll-like receptor 3 (TLR3) recognizes double-stranded RNA, which is a molecular signature of viruses, and plays a pivotal role in host defense against viral invasion. Polymorphisms in the human TLR3 gene have been shown to affect the receptor function and to be associated with a variety of diseases, suggesting correlations between TLR3 polymorphisms and the disease resistance/susceptibility in pigs.

Transcriptional analysis of the porcine TTID gene and association of different TTID genotypes with carcass traits

J. Wang, Feng, Y. - P., Zuo, B., Xiong, Y. - Z., and Deng, C. - Y., Transcriptional analysis of the porcine TTID gene and association of different TTID genotypes with carcass traits, vol. 13, pp. 1195-1202, 2014.

The titin immunoglobulin domain (TTID) protein localizes to the Z line in muscle and binds to alpha-actinin and gamma-filamin. It plays an indispensable role in stabilizing and anchoring of thin filaments. In this study, the 5'-regulatory region of the porcine TTID gene was analyzed with bioinformatic methods. Another objective of this study was to further investigate the polymorphism in the intron 6 of the porcine TTID gene. We determined allele frequency among six Chinese porcine purebreds.

Development-related expression patterns of protein-coding and miRNA genes involved in porcine muscle growth

F. J. Wang, Jin, L., Guo, Y. Q., Liu, R., He, M. N., Li, M. Z., and Li, X. W., Development-related expression patterns of protein-coding and miRNA genes involved in porcine muscle growth, vol. 13, pp. 9921-9930, 2014.

Muscle growth and development is associated with remarkable changes in protein-coding and microRNA (miRNA) gene expression. To determine the expression patterns of genes and miRNAs related to muscle growth and development, we measured the expression levels of 25 protein-coding and 16 miRNA genes in skeletal and cardiac muscles throughout 5 developmental stages by quantitative reverse transcription-polymerase chain reaction.

Correlation of forkhead box transcription factor O1 and myosin heavy chain isoforms in porcine skeletal muscle

X. E. Shi, Song, Z. Y., Yang, Q. M., Liu, Y. G., and Yang, G. S., Correlation of forkhead box transcription factor O1 and myosin heavy chain isoforms in porcine skeletal muscle, vol. 13, pp. 10231-10240, 2014.

We examined the expression of myosin heavy chain (MyHC) isoforms and forkhead box transcription factor O1 (FoxO1) in porcine soleus and extensor digitorum longus (EDL) muscles to clarify the correlation of FoxO1 and the relative abundance of transcripts of MyHC isoforms. Soleus muscle was found to be redder than EDL muscles in pigs, and immunohistochemical fast MyHC staining showed more oxidative type I fibers compared to EDL.

Molecular cloning and expression of the porcine S14R gene in Escherichia coli

Y. J. Guo, Liu, G. Z., Wang, C. M., Wang, Y. Y., Li, H. J., Zhong, K., Lu, W. F., Wang, Y. L., and Yang, G. Y., Molecular cloning and expression of the porcine S14R gene in Escherichia coli, vol. 12, pp. 4405-4412, 2013.

We amplified S14R protein gene cDNA of porcine, cloned it into a prokaryotic expression plasmid, and expressed it in Escherichia coli. A pair of primers was designed based on the cDNA sequence of the porcine S14R gene in GenBank. The target gene fragment from porcine liver tissue was amplified by RT-PCR. Confirmed by auto-sequencing, the target gene fragment was subcloned into an expression vector of pET28a. The pET28a-S14R construct was subsequently transformed into E. coli BL21 (DE3).
