transgene expression r26
(transgene expression allowed) demonstrate doxycycline-dependent mCherry expression. (D) Schematic of targeted Rosa26 locus and Southern screening strategy. The Rosa26 locus in E14 ES cells was targeted by homologous recombination with the Exp-R26(EF1α-tTA/TetO-mCh-Rs1) construct. Regions in hatch marks indicate the 5' and 3' homology regions of the targeting vector and the endogenous Rosa26 locus (abbreviated R26 in the figure). The location of the 5' recombination Southern probe and HindIII restriction sites are indicated. (E) Southern blots of genomic DNA digested with HindIII and probed as in (D). Heterozygous ES cells at the Rosa26 locus are indicated by the two bands. " width='250' height="auto" />

Figure Legend Snippet: A single-vector tetracycline construct allows doxycycline-regulated expression . (A) Overview showing the regulator plasmid containing the EF1α-tTA cassette (pEntL1L3-EF1α-tTA, left) and the responder plasmid containing the TetO-mCh-Rs1 cassette (pEntR3L2 TetO-mCh-Rs1, right). The mCherry and Rs1 cistrons are separated by a P2A ribosomal skip sequence to allow simultaneous expression of both peptides. The entry plasmids were recombined using Gateway technology into the desired destination vector containing the AttR1 and AttR2 Gateway sites. The TetO and EF1α-tTA portions are in opposite orientation (indicated by upside-down text) to minimize steric hindrance between the two promoters, as well as potential cross-activation of the TetO by the EF1α promoter. In addition, flanking insulator sequences are included to minimize any read-through activation of the constructs by surrounding promoters (such as Rosa26) that may lead to "leakiness" or steric interference from endogenous promoter activity. (B, C) HEK-293 cells carrying the Exp-pcDNA3.2(EF1α-tTA/TetO-mCh-Rs1) expression cassette and cultured in doxycycline (suppressed expression) or in the absence of doxycycline (transgene expression allowed) demonstrate doxycycline-dependent mCherry expression. (D) Schematic of targeted Rosa26 locus and Southern screening strategy. The Rosa26 locus in E14 ES cells was targeted by homologous recombination with the Exp-R26(EF1α-tTA/TetO-mCh-Rs1) construct.

Figure Legend Snippet: Diagram of the Pgk-1 promoter. The solid line represents the DNA sequence upstream of the Pgk-1 ). The cross-hatched bars labeled ES, EA, and AS are the probes used for EMSA and DNasel footprinting experiments. The slashed, black, and gray boxes labeled R1, R2, and R3 refer to the regions within the UAS that bind nuclear proteins. The black box labeled R2 was defined by both DNase1 footprinting and EMSA whereas the slashed and gray boxes labeled R1 and R3 were shown to bind protein by EMSA only; no footprints were obtained over these regions. The locations of R1 and R3 were established by EMSA with oligonucleotide probes or with DNA fragments from the promoter region. The distribution of nuclear DNA binding factors is indicated below the promoter diagram where the intensity of the signal is roughly proportional to the size of the bars.
Techniques Used: Sequencing, Labeling, Footprinting, Binding Assay

Figure Legend Snippet: R26(EF1α-tTA/TetO-mCh-Rs1) function in mouse ES cells . (A) FACS analysis showing doxycycline-inducible mCherry expression in E14 mouse cells carrying the Exp-R26(EF1α-tTA/TetO-mCh-Rs1) construct. (B) Induction of Rs1 expression and treatment with the agonist RS67333 results in increased cAMP accumulation in mouse ES cells. Both basal and ligand-induced increases in cAMP are detectable. In addition, serotonin does not induce increased cAMP accumulation in either the wildtype or Rs1-expressing cells. (C) Schematic showing the differentiation protocol for making suspension EBs. (D) Expression and ligand activation of Rs1 during EB formation results in larger EB size. (E) Quantitation of EB size in the different culture conditions using ImageJ. A minimum of 114 EBs were measured for each condition. The analysis was performed on three separate EB differentiation experiments with similar results. Error bars represent average +/- 1 SD.
