Figure 5A. Biochemical synthesis of PtdIns4P from PtdIns by sequential reactions catalyzed by MavQ, LepB_NTD and SidF. MavQ was reacted with di-C8-Bodipy-FL-PtdIns, resulting in the production of PtdIns3P (lane 6). The PtdIns3P-specific PI4K LepB-NTD was then added into the reaction, yielding PtdIns(3,4) P2 (lane 7). The product of the sample receiving LepB_NTD was further incubated with the 3-phosphatase SidF to yield PtdIns4P (lane 8). The lipid products were detected and visualized by TLC. A schematic illustration of the enzymatic reactions is shown in the lower panel. B. Representative images of SidC anchoring on LCVs. BMDMs infected with the indicated L. pneumophila strains at an MOI of 2 for 2 h were sequentially stained with antibodies against the bacteria and SidC.

Activation of one allele of β-catenin in Lgr5-positive stem cells does not result in colonic lesions.Figure 2Table shows that only homozygous activation of β-catenin (Lgr5CreER Catnblox(ex3)/lox(ex3)) or loss of Apc (Lgr5CreER Apcfl/fl) in Lgr5-positive stem cells results in colonic lesions in cohorts, sampled when signs of sickness were apparent. There were no lesions observed when only one allele of β-catenin (Lgr5CreER Catnblox(ex3)/+) was mutated (chi-squared test, P < 0.001). Colonic lesions were scored from H&amp;amp;E by identification of disorganised epithelium. Staining for β-catenin and SOX9 confirmed activation of Wnt signalling in the observed lesions.

Figure 5Sanger sequencing validation of RNA editing of the LIMD1 (A) and VHL (B) transcripts. Downregulation of ADAR1 levels in MCF7 cells was done using specific siRNAs. Cells were then subjected to hypoxia treatment for 5 hrs. The extent of knockdown and gene alterations was monitored by western blotting using antibodies targeting LIMD1, VHL, PHD1, PHD2, ADAR1 and HIF-1α, as indicated β-actin was used as loading control. To characterize subcellular distribution of target transcripts, real-time PCR analysis was done on the fractionated MCF7 cells with the indicated experimental treatments. Translation efficiency was determined by quantifying transcript association with the polyribosome fraction, using ADAR1-depleted MCF7 cells with hypoxia treatment. The abundance of LIMD1 in polysomes was analyzed by real-time PCR and normalized by the eEF1α levels. To inspect HIF-1α protein abundance and modification with ubiquitin, anti- HIF-1α, anti-ubiquitylation (Ub), and anti-VHL immunoprecipitation experiments were performed, coupled with immunoblotting detection of ubiquitylation and HIF-1α, as indicated. MCF7 cells transfected with ADAR1 siRNA and treated with hypoxia were used. Protein signals were quantified using the ImageJ software. The fold changes of protein levels were determined on the basis of immunoreactive signals normalized by the input (In), with the control (siGFP) group being represented as 1.
