In Bombyx mori. And they have combined effects on the uptake and transport of cellular lutein. Semiquantitative RT-PCR Analysis Total RNA was isolated from midguts and silk glands of last instar Bombyx mori buy BIBS39 larvae stage at 3, four, five and six days of age by using Trizol reagent. Reverse transcription was Licochalcone A performed by using Oligo primer and MMLV reverse transcriptase. Then cDNA was employed as a template to test Cameo1, Cameo2, CBP and actin A3. Each of the primers had been designed by Primer Premier 5.0 software and purchased from Invitrogen. Each and every tissue was tested in triplicate for total RNA isolation, cDNA synthesis and RT-PCR. Components and Approaches Insect Material Bombyx mori strains were preserved in the Silkworm Gene Bank at Southwest University, China. The larvae were reared on fresh mulberry leaves until the last instar larvae at 25uC beneath 12 h light, 12 h dark cycles. 4 Bombyx mori strains with unique colors of cocoons had been made use of: Qiubai was utilised because the genotype of. Dazao has the genotype , Jianpuzhai has the genotype and 03-520 was used as the genotype of . Midguts, hemolymph and silk glands have been obtained from last instar larvae stage at three, four, 5 and 6 days of age and stored at 280uC till use. Construction of Expression Vectors The pEGFP-N1, pcDNA3.1/V5-His B, pBiFCVC155 and pBiFC-VN173 vectors were made use of in this study. By sequence alignment of CBP in Silkworm Genome Database, a truncated CBP was found and named as cbp. Comparing to CBP protein structure, cbp lacks the 79 amino acids on Nterminal, and has 5 mutations in amino acids residues, resulting in an incomplete steroidogenic acute regulatory protein related lipid transfer domain. In this study, cbp was made use of as non-functional substitute of CBP. Cameo1, Cameo2, CBP, cbp and EGFP had been cloned, cleaved and ligated into different expression vectors by utilizing unique primers and restriction endonucleases. 2 Interacting Proteins Mediate Lutein Uptake Reaction Variety RT-PCR Gene Name actin A3 Primers F: AACACCCCGTCCTGCTCACTG R: GGGCGAGACGTGTGATTTCCT Product Size 666 Tm 55 RT-PCR/pcDNA3.1 B Cameo1 F: TTCGGGGTACCATGGAGATGGTGTCTTCCGGAG R:TCTAGTCTAGAGATTGTTGATTCTCTTGTGACGCAC 1485 60 Cameo2 F: TTCGGGGTACCATGGGTGGTGGTTTGTTGAG R: TCTAGTCTAGAGATATAGGATTCAGTTTCATTTCCGC 1482 60 CBP F: TTCCCAAGCTTATGGCCGACTCTACGTCGAAAAG R: TCTAGTCTAGAGAGAATTCGGCTCTGGCCTTCG 891 64 pcDNA3.1 B cbp F: TTCCCAAGCTTATGGCGAACGCTTGGCG R: TCTAGTCTAGAGAGAATTCGGCTCTGGCCTTCG 654 63 EGFP F: TTCGGGGTACCATGGTGAGCAAGGGCGAG R: TCTAGTCTAGAGACTTGTACAGCTCGTCCATGCC 717 58 pEGFP-N1 Cameo2 F: TTCCGGAATTCCCCGTGGTGGTTTGTTGAGATG R: AACCGCTCGAGCTATAGGATTCAGTTTCATTTCCGCT 1479 60 CBP F: TTCCCAAGCTTGCCGACTCTACGTCGAAAAGC R: CCTAGTCTAGAGAATTCGGCTCTGGCCTTC 888 60 pBIFC-VC155 Cameo1 F: TTGGAAGATCTGCAAGATGGTGTCTTCCGGAGT R: TTCGGGGTACCTTGTTGATTCTCTTGTGACGCA 1482 58 Cameo2 F: TTCCGGAATTCCCCGTGGTGGTTTGTTGAGATG R: AACCGCTCGAGCTATAGGATTCAGTTTCATTTCCGCT 1479 60 pBIFC-VN173 CBP F: TTCCCAAGCTTGCCGACTCTACGTCGAAAAGC R: CCTAGTCTAGAGAATTCGGCTCTGGCCTTC 888 60 cbp F:TTCCCAAGCTTGCGAACGCTTGGCGC R: CCTAGTCTAGAGAATTCGGCTCTGGCCTTC 651 59 F: forward primer; R: reverse primer. doi:ten.1371/journal.pone.0086594.t001 Cell Culture and Transient Transfection Human embryonic kidney 293 cells have been grown in Dulbecco’s Modified Eagle Medium with 10% fetal bovine serum and incubated at 37uC in 95% O2/5% CO2. 1 day before transfection, HEK293 cells were seeded at a density of 0.5610526105 cells/cm2 on glass cover slips in 24-well plates or 6-well plates.
