E. qRT-PCR was performed to evaluate the effect of iron starvation following TfR RNAi on known homologues of iron-dependent proteins (IDPs). Relative mRNA levels of selected homologues of IDPs in BSF trypanosomes are demonstrated. The relative quantity of each transcript was normalized against (Tb927.3.720) relative to un-induced settings. Abbreviations: E6 (ESAG6), E7 (ESAG7), RBP5 (RNA-binding Protein 5; Tb927.11.12100), PAP2 (Phosphatidic Acid Phosphatase; Tb927.8.480), Hyp#1 (hypothetical protein; Tb927.8.490), Hyp#2 (hypothetical protein, Tb927.8.510); FeRed-1 (Ferric Reductase, Tb927.6.3320), FeRed-2 (Ferric Reductase, Tb927.11.4430); HpHbR (Haptoglobin Hemoglobin Receptor, Tb927.6.440), IRT1 (Iron Transporter, Tb927.11.8990); IRT2 (Iron Transporter, Tb927.11.9000); TAO (Trypanosome Alternate Oxidase, Tb927.10.7090), ACO (Aconitase), MLP (Mucolipin, Tb927.7.950), RNR1 (Ribonucleotide Reductase, Tb927.11.7840); RNR2 (Ribonucleotide Reductase, Tb927.11.12780). Data are means SD (= 3 technical replicates, with 3 technical replicates for each N-terminal tagging of RBP5 with 6xHA retaining its native 3-UTR. Selection of transgenic cells was accomplished using puromycin (PAC) and Hygromycin (Hyg). Arrows show position of PCR primers to verify RBP5 locus-specific integration. The Pralidoxime Iodide related size fragments are demonstrated by genomic DNA (gDNA) PCR from Pralidoxime Iodide crazy type (WT), solitary allele (Hyg) or both alleles (Hyg/Pac) tagged cell lines. All diagrams are not drawn to level Mouse monoclonal to CD22.K22 reacts with CD22, a 140 kDa B-cell specific molecule, expressed in the cytoplasm of all B lymphocytes and on the cell surface of only mature B cells. CD22 antigen is present in the most B-cell leukemias and lymphomas but not T-cell leukemias. In contrast with CD10, CD19 and CD20 antigen, CD22 antigen is still present on lymphoplasmacytoid cells but is dininished on the fully mature plasma cells. CD22 is an adhesion molecule and plays a role in B cell activation as a signaling molecule and tags were carried out by CRISPR/Cas9-mediated PCR-based method published in [36]. B. Schematic shows strategy for generating C-terminally tagged RBP5 (RBP5::mNG-Ty) Pralidoxime Iodide fused with 3-UTR and hygromycin (HYG) as drug selection cassette. Arrows show position of PCR primers to analyse right integration with related size fragments demonstrated in agarose gel on the right. CRISPR/Cas9 mediated tagging strategy in (a) was used. C. Effect of iron starvation on C terminal epitope tagged RBP5 protein manifestation. Schematic of C-terminal tagged RBP5 (RBP5::mNG-Ty) fused with PFR 3-UTR. RBP5::mNG-Ty expressing cells were incubated with deferoxamine [25 M, 5 hr or 5 M, 24 hr]. Pralidoxime Iodide Total protein was extracted and blotted with Ty or BiP antibodies. RM, M indicate RBP5::mNG-Ty and mNG::Ty polypeptides, respectively. Pub chart (ideal) shows quantification of RBP5::mNG-Ty relative to BiP signals. D. Effect of iron starvation on mRNA large quantity by Northern blot analyses. Log phase BSF cells (~5×105 cells/ml) were incubated with deferoxamine (DFO), Iron (III) chloride (Fe) or untreated (Ctrl), RNA was isolated and analysed by Northern blotting with probes to full size ORF plus 1,235 bp downstream of the STOP codon. The blot was re-probed with 5.8S rRNA as loading control [70]. For each sample, RBP5 mRNA levels were quantified relative to 5.8s rRNA and shown as Qty beneath the blot. In contrast to curated and experimental data of poly A sites from TritrypDB, these data (from a single experiment) show the RBP5 3-UTR is definitely ~1.291 Kb from your predicted STOP codon. Also note that RBP5 appears within the blot as solitary homogenous species suggesting no additional processing occurs following DFO treatment.(TIF) ppat.1009696.s004.tif (2.2M) GUID:?4427C978-78E3-4485-8D0E-2E564B5A48BC S5 Fig: RNAi and knockout.
