Ined in culture by continuous subculturing.DNA sequence Title Loaded From File analysis of goat GLUT1 and GLUTThe analysis of the cDNA sequences was conducted using the computer program DNASTAR (DNASTAR, Madison, WI), the National Center for Biotechnology Information BLAST site Table 1. Sequences of oligonucleotide primers used for PCR and RT-qPCR.Detection of GLUT1, GLUT12, sweet1 and amino acid transporters (AATs) gene expression by RT-qPCRTotal RNA from cells stably transfected with pcDNA3.1GLUT1, pcDNA3.1-GLUT12 and pcDNA3.1 was obtained, and the 18S and 28S rRNA bands were evaluated following agarose gel electrophoresis. The GeneJETTM RNA Purification Kit (Fermentas) was used with oligo dT and 6-random primers to reverse-transcribe 5 mg of total RNA into cDNA. To determine the gene expression profiles, 2 mL of the cDNA was amplified in a 20 mL reaction mixture containing 10 mL SYBR PremixTM Ex Taq (TaKaRa China CA), 0.4 mL ROX dye II and specific primers (0.4 mM each of the forward and reverse gene-specific primer; Table. 1) using an ABI 7500 instrument. The data are reported as values normalized to the housekeeping gene (b-actin) to account for repeated measures. The differences between the means at each stage of development were determined by Fisher’s protected LSD test.Primers names GLUT1-F GLUT1-R GLUT1-F2 GLUT1-R2 GLUT12-F GLUT12-R GLUT12-F1 GLUT12-R1 GLUT1-F2 GLUT1-R2 GLUT12-F2 GLUT12-R2 SWEET1-F SWEET1-R SLC1A5-F SLC1A5-R SLC7A5-F SLC7A5-R SLC3A2-F SLC3A2-R ?actin-F ?actin-RType Forward Reverse Forward Reverse Forward Reverse Forward Reverse Forward Reverse Forward Reverse Forward Reverse Forward Reverse Forward Reverse Forward Reverse Forward ReverseSequences 5′-GCTAGCATGGAGCCCACCAGCAAG -3′ 5′-AAGCTTTCACACTTGGGAATCAGCTCC -3′ 5′-CTGGTTCTGTTCTTCATCTTC-3′ 5′-CTCCTCAGGTGTCTTGTC-3′ 5′-GGAAAAGTGACCGCTCGTG-3′ 5′-TGTCCTGGTAGGCAAAGAACTG-3′ 5′-CTCGAGATGGTACCTGTTGAAAACGCAG -3′ 5′-CTCGAGTTAGATCTCTGAAGAAAGCTGC -3′ 5′-CTGGTTCTGTTCTTCATCTTC-3′ 5′-CTCCTCAGGTGTCTTGTC-3′ 5′-TACTCTCCTGTCGTCTGT-3′ 5′-ATGATGGTGGCTCTTCTC-3′ 5′-GTGCTCCTTCAGACTACA-3′ 5′-GTGGTGAGAGGTACATACT-3′ 5′-CCAAGGGACTCTCAAACATTTCA-3′ 5′-CGGAGGCTAGAACTTTCAAGAA-3′ 5′-ATCGCCGTCTCCTTCTGG-3′ 5′-CTGGTTCTGGTCGCTTACG-3′ 5′-GCTGCTGCTGCTCTTCTG-3′ 5′-TGCCACCATCTCTGCTCTG-3′ 5′-CCAACCGTGAGAAGATGA-3′ 5′-CAGAGTCCATGACAATGC-3’Detection of glucose absorption and lactose synthesisThe GT1-GMGE, GT12-GMGE and GMGE cells were passaged at the same density in 6-well plates, and the cell culture medium and the total protein content of the cells were sampled at 24 h and 48 h. The glucose and lactose levels in the culture media were determined using the Glucose Assay Kit II and Lactose Assay Kit (Biovision, CA, USA), respectively. The absorbance was measured using a spectrophotometer at a wavelength of 450 or 570 nm. The amount of absorbed glucose or lactose, as determined based on the difference before and after incubation, was expressed as mg of glucose/mg protein or ng of lactose/mg protein.Detection of GLUT1 and GLUT12 in GMGE cellsThe GT1-GMGE, GT12-GMGE and GMGE cells were grown on coverslips, fixed with 4 paraformaldehyde for 30 min Title Loaded From File anddoi:10.1371/journal.pone.0065013.tFunctional Analysis of GLUT1 and GLUTFigure 1.
