    Curcumin decreases BRCA1 occupancy at the HIV-1 LTR. A . TZM-bl cells were transfected with pcTat and treated the next day with vehicle (DMSO) or a titration of curcumin (0.5, 1, 10, and 20 μM). Samples were analyzed by western blot. Inset depicts a dose–response curve of BRCA1 protein abundance versus curcumin treatment based on the average densitometry counts with error bars representing standard error of three independent measurements. Western blot is representative of three independent experiments. Densitometry counts were taken from three independent treatments to acquire a dose–response curve of BRCA1 expression inhibition (inset plot) B . TZM-bl cells were transfected with pcTat and treated the next day with DMSO or 20 μM curcumin. Bright-Glo luciferase assays and CellTiter-Glo cell viability assays were performed 24 hours post-treatment as described by the manufacturer. Data was normalized to cells containing Tat and treated with DMSO as baseline for Tat-dependent LTR activation. Transfection and treatment assays were performed in triplicate and data plotted represents averaged data of two independent experiments. Error bars show the standard error of two averaged independent measurements. Viability assays were performed in triplicate. C . TZM-bl cells were transfected with pcTat and treated the next day with DMSO or curcumin (20 μM) for 24 hours prior to being collected for ChIP analysis. Antibodies used for ChIP were anti-BRCA1 (10 μg), anti-IgG (10 μg), and anti-RNA polymerase II (RNAP II, 10 μg).

    Qiagen qiaquick pcr purification kit
    Evaluation of TPW for different silica-column NA extraction kit protocols on pure water samples using ( a – c ) qPCR and ( d – f ) LAMP. All reactions were spiked with 5 × 10 4 copies λ phage DNA and primers. By manufacturer protocol, the ( a , d ) Zymo Quick-DNA/RNA Viral Kit and ( b , e ) Zymo ZR Viral DNA/RNA Kit do not include the dry spin (+dry spin) whereas the ( c , f ) Qiagen <t>QIAquick</t> <t>PCR</t> Purification Kit does. The left of each graph shows high dilution and the right shows low dilution. Each bar represents the result from a single qPCR or LAMP measurement. We ran 27 silica-column extractions (3 silica columns × 3 conditions × 3 extraction protocols) and the kit extract was shared between high and low dilutions of both qPCR and LAMP. Dashed lines show the C q or TTP for a reaction without inhibitors (“No Extract”). Samples marked N.D. were not detected within either 40 cycles or 40 min. ( a – f ) We asked whether the manufacturer protocol replicates (“No Dry Spin for Zymo kits, “+dry spin” for Qiagen kit) fell within the 95% CI of the corresponding +1-undecanol condition for the low kit extract dilution case. The number of replicates that lie outside the 95% CI are indicated by the number of + (above) and - (below).

    ChIP analysis of histone modification at the SYBL1 promoter region. Allele-specific ChIP analysis for H3 acetylation and H3 K4 methylation was performed using an XhoI polymorphism in the 5' UTR of the SYBL1 gene in the Xq28 pseudoautosomal region that is also present on the Y chromosome. In normal male cells, the Y-linked locus is inactivated, hypermethylated, and late-replicating as is the inactive X allele in female cells [23,31,49]. To determine if this region has abnormal histone modifications on the X-inactivated but DNA hypomethylated ICF female X, ChIP assays were performed for acetylated histone H3 (acH3) and K4-methylated histone H3 (mK4) in normal male lymphoblasts and in PT3 ICF female fibroblasts; the ethidium bromide-stained gels of each sample are shown before and after digestion with XhoI. The undigested alleles (XhoI+) are 268 bp; the digested alleles (XhoI-) result in fragments of 108 and 260 bp. The ChIP assay for acetylated histone H3 (acH3) shows that only the XhoI-digested allele (XhoI+) is hyperacetylated in a normal male lymphoblast (NMLB1), and this corresponds to the active X allele (Xa) by RT-PCR (data not shown). An hTERT-transformed clone of PT3 ICF fibroblasts was also analyzed by ChIP. This clone has normal monoallelic expression of SYBL1 even though the promoter region is extremely hypomethylated as determined by bisulfite methylation analysis of DNA. The inactive X allele in the PT3 clone is hypoacetylated at histone H3 and hypomethylated at H3K4 because only the active X allele (XhoI-) is immunoprecipitated with either the acetylated or K4-methylated histone H3 antibodies (although a small portion of the inactive X also appears to have been precipitated by the acetylated H3 antibody).
