Test results showing lack of cross - reactivity of bovine leukemia virus (BLV)–specific primers with representatives of all mammalian and avian retrovirus subfamilies and human exogenous and endogenous viruses previously identified in human breast tissue. Nested liquid-phase PCR used primers from 5 BLV genome regions with template DNA from the viruses in lanes 4–10 and 12–21. PCR products for each virus, loaded into 1 well, were separated by agarose gel (1.5%) electrophoresis on the basis of size differences. Amplicons were generated only for known BLV-positive cell lines (FLK and Bat 2 Cl 6 ). Samples in lanes 13–21 were run simultaneously in the same gel in wells below samples in lanes 4–12.

Human GAPDH primers were used for human, rhesus monkey, baboon, and bat cell lines (amplicon = 237 bp); murine GAPDH for mouse and rat cell lines (796 bp); and bovine GAPDH for bovine, ovine, and feline cell lines (857 bp).

Identification of mice with B cell-specific deletion of ILK. Mice with B cell-specific deletion of ILK were identified through PCR (a) and flow cytometry (b) and Western blot (c). (a) DNA from the tail was amplified by PCR and then separated and visualized on 2% agarose gel to identify the mice with floxed ILK genes: L: TrackIt™ 100 bp DNA ladder; WT: ILK WT/WT ; H: ILK flox/WT ; and F: ILK flox/flox . (b) Identification of mice with CD19 WT/WT , CD19 Cre/WT , or CD19 Cre/Cre genotype was done by flow cytometric analysis on the blood that was double-stained with CD19 (FITC) and CD45R/B220 (PE/Cy5). Mice with CD19 Cre/Cre genotype did not display CD19 on the outer surface of the B cells. CD19 Cre/WT mice still expressed CD19 on the outer surface of the B cells, but at a lower density than CD19 WT/WT mice which consequently translated in a lower MFI compared to CD19 WT/WT mice. The similar percentages of gated CD45R/B220 + cells with equal MFI demonstrated that there was no loss in the B cell population in CD19 Cre/WT mice and CD19 Cre/Cre mice compared to CD19 WT/WT mice. (c) Western blot was performed on splenocytes and on splenic B cells from mice identified as being ILK wild type (WT, CD19 WT/WT /ILK flox/flox ) or ILK knockout (KO, CD19 Cre/WT /ILK flox/flox ). High expression of ILK was observed in the splenocytes of WT and KO mice, but ILK was not detected in the B lymphocytes of the latter.

Amplification of bovine leukemia virus (BLV) genome regions in human breast tissue specimens. Nested liquid-phase PCR, using primers from 5 BLV genome regions, was used to amplify products from DNA extracted from breast tissues of 6 human donors. PCR products for each tissue were loaded into 1 well and separated by agarose gel (3.5%) electrophoresis on the basis of size differences: long terminal repeat, 290 bp; group-specific antigen, 272 bp; envelope, 230 bp; trans-activating gene of the X region, 206 bp; polymerase, 157 bp. The section below the white line shows the glyceraldehyde 3-phosphate dehydrogenase amplification of each sample as an indicator of DNA quality.

BLV-specific DNA in human breast tissue amplified and detected by PCR-in situ hybridization. A) Breast tissue specimen diagnosed as invasive pleomorphic lobular carcinoma. Three streaks of BLV-positive (brown staining) mammary epithelial cells are seen invading through connective tissue (fibroblasts and adipocytes) that is largely BLV-negative. Positive reactions in mammary epithelial cells are in cytoplasm (diffuse light brown reaction) of most mammary epithelial cells, and nuclei of some cells (diffuse brown reaction as well as dark dots) and as compared to B) Adjacent tissue section without the BLV-specific ISH probe in the hybridization mix. This serves as a background control against which to compare A, and also a control for reactions due to artifacts inherent in some tissues (excess peroxidase and/or melanin). No brown cells are apparent in B. C) Breast tissue specimen diagnosed as benign ductal hyperplasia (normal). Note oval nest of BLV-positive mammary epithelial cells tightly surrounded by fibroblasts that are BLV-negative. Positive reactions in the mammary epithelial cells are intense in the cytoplasm and some cells have evidence of positive nuclear reactions (dark brown dots). D) Background control for C has no apparent brown cells. Light counterstain for all specimens illustrated is Difquick blue and the magnification is x40.

Confirmation of microarray results by RT-PCR. cDNA of PA6-DA, PA6-X and MM55K cell lines were analyzed by RT-PCR using gene specific primers for the five candidate genes selected from the microarray data. RT-PCR analysis reproduced the results of cDNA microarray for all five genes, including SDF-1, IGF2, IGFBP4, PTN, and EFNB1. Amplification was performed for 35 cycles. GAPDH was amplified simultaneously as an internal control under the same conditions.

Wild-type and escape mutant KP9 viruses are represented by closed squares and open triangles, respectively, throughout. Cloning and sequencing (open squares) was compared to qRT-PCR (closed squares) to establish the proportions of wild-type KP9 virus in animal 4292 (C). A mean of 25 clones were sequenced across KP9 for each time point.

Quantitative real-time PCR analysis of selected genes for RNA-Seq validation (experiment 2). Across 20 comparisons (10 genes × 2 heifer groups [pregnant vs. cyclic]), the expression pattern of the selected genes obtained by qPCR was consistent with the results from the RNA-Seq analysis in all but two cases ( QRFPR and CCL20 ). For each transcript, bars with different superscripts differ significantly ( P

Quantitative PCR to estimate efficiency of programmed mutagenesis. ( A ) The three primers (tri-primer set): Smω1-OVR-F (probe at gRNA, expected DSB and KI sites as red bar and arrow), Smω1-OUT-F and shared Smω1-reverse primer locations used in SYBR green-based PCR to estimate efficiency of on-target, programmed CRISPR/Cas9 gene editing. Estimation of gene-editing efficiency was determined as described ( Shah et al., 2015 ; Yu et al., 2014 ). ( B ) Relative fold amplification efficiency; the ratio of OVR:OUT (gray bar) was set at 100% for control DNA sample, and little or no reduction was observed in relative fold amplification compared to other control groups, including groups exposed to culture medium only, sgRNA only, Cas9 only, ssODN only, heat-killed pLV-ω1X6 virions and ssODN. By contrast, there was reduced relative fold amplification of 2.5%, 6.9%, 4.5% and 12.5% in the experimental groups, RNP, RNP and ssODN, pLV-ω 1X6 virions, and pLV-ω 1X6 virions and ssODN, respectively. Percentages of relative fold amplification differed significantly among control and experiment groups. Means ± SE were established from eleven biological replicates.

MIP-3α and CCR6 transcripts are up-regulated in the CNS of SJL mice with PLP 139-151-induced EAE. RNA was extracted from different CNS areas and from control tissues (spleen and small intestine), reverse-transcribed, and subjected to PCR amplification using MIP-3α- and CCR6-specific primers, as described in Materials and Methods. A RT-PCR using glyceraldehyde-3-phosphate dehydrogenase-specific primers is also shown as an internal control. RNA was extracted from control mice (PBS/CFA-injected) and from mice at the indicated EAE stages. The data shown were obtained in mice with grade 3 acute EAE and grade 4 relapsing EAE. The PCR products were visualized by ethidium bromide staining. Lane 1 , cerebrum; lane 2 , cerebellum; lane 3 , spinal cord; lane 4 , spleen; and lane 5 , small intestine.

    Disruption of the moxY gene via double-crossover recombination. (A) To disrupt the moxY gene, gene disruption vector pMOXY-DD was constructed as described in the text. The vector was linearized and then transformed into the wild-type strain SYS-4. The double-crossover recombination resulted in the replacement of most of the internal section of the target gene moxY with the ptrA gene. (B) PCR analysis of the moxY disruptant was conducted with genomic DNA of MOXY-DD-69 and the recipient strain SYS-4 by using different combinations of primers.
