Ailuropoda melanoleuca; ATP5G1; cDNA cloning; Giant panda; Overexpression

The ATP5G1 gene is one of the three genes that encode mitochondrial ATP synthase subunit c of the proton channel. We cloned the cDNA and determined the genomic sequence of the ATP5G1 gene from the giant panda (Ailuropoda melanoleuca) using RT-PCR technology and touchdown-PCR, respectively. The cloned cDNA fragment contains an open reading frame of 411 bp encoding ... more

Ailuropoda melanoleuca; cDNA cloning; Giant panda; Overexpression; RPS13 gene; Sequence analysis

The cDNA and the genomic sequence of ribosomal protein S13 (RPS13) of the giant panda (Ailuropoda melanoleuca) was cloned using reverse transcription-polymerase chain reaction (RT-PCR) and touchdown-PCR, respectively. These two sequences were sequenced and analyzed, and the cDNA of the RPS13 gene was overexpressed in Escherichia coli BL21. We compared ... more

cDNA cloning; Fiber strength; Gossypium barbadense; Phosphatidylinositol 4-kinase; Real-time PCR

Sea Island cotton (Gossypium barbadense) is highly valued for its superior fiber qualities, especially fiber strength. Based on a transcript-derived fragment originated from transcriptome QTL mapping, a fiber strength related candidate gene of phosphatidylinositol 4-kinase cDNA, designated as GbPI4K, was first cloned, and its expression was characterized in the secondary ... more

Fusion protein; Giant panda; Interleukin-6/interleukin-2; Prokaryotic expression

To construct a fusion cytokine protein with more and stronger bioactivities to enhance the immunity of the cytokine alone, we expressed interleukin (IL)-6/(IL)-2 from giant panda (Ailuropoda melanoleuca) in Escherichia coli as a 59.4-kDa fusion protein. Subsequently, the inclusion bodies were solubilized with 8 M urea and applied onto a Ni-nitrilotriacetic acid column. ... more

Bioactivity analysis; Giant panda; Interleukin 18; Molecular cloning

Interleukin 18 (IL-18), as a member of IL-1 superfamily, is an important pleiotropic cytokine that modulates Th1 immune responses. In this report, we cloned and identified a homolog of IL-18 in giant panda (Ailuropoda melanoleuca) (designated as AmIL-18) from peripheral blood mononuclear cells stimulated with lipopolysaccharide. The open readin g frame of AmIL-18 cDNA is ... more

cDNA cloning; hLIF; Oral mucous membrane; Overlap PCR

Complementary DNA (cDNA) is valuable for investigating protein structure and function in the study of life science, but it is difficult to obtain by traditional reverse transcription. We employed a novel strategy to clone human leukemia inhibitory factor (hLIF) gene cDNA from genomic DNA, which was directly isolated from the mucous membrane of mouth. The hLIF sequence, which is 609 bp ... more

Bioinformatic analysis; cDNA cloning; Parathyroid hormone-related protein; Tissue expression analysis; Water buffalo

Parathyroid hormone-related protein (PTHrP) is involved in the deposition of milk calcium in mammal lactation, but its role in buffalo is unclear. In this study, the full-length coding sequence of the water buffalo PTHrP gene was first isolated using reverse transcription-polymerase chain reaction. The protein was then subjected to molecular characterization using bioinformatic ... more
