figf1Single-marker association results for the combined non-Jewish and Jewish samples using the Cochran-Mantel-Haenszel (CMH) test. Each chromosome is depicted as a different color. The red line indicates the threshold (P 5 × 10−5) selected to define regions for evaluation in the replication studies. The P value thresholds for suggestive and significant associations are 3.28 × 10−6 and 1.64 × 10−7, respectively, based on a Bonferroni correction for multiple testing. A modest correction factor (λ = 1.056) is necessary to correct for stratification between cases and controls, but it does not modify the current results.
figf2(a-c) We used quantitative real-time PCR to determine the expression patterns of ATG5 (a), ATG7 (b) and ATG16L1 (c) in various human immune and epithelial cell lines. ATG5 was broadly expressed in the cell lines studied (a), with between 1.5- and fourfold variations in expression level across the cell lines. ATG7 expression (b) was broadly comparable to that of ATG5, with the exception of THP1 cells, which showed 35-fold higher expression than SW480 cells. ATG16L1 expression (c) was also broadly similar to that of ATG5 and ATG7 (except for ATG7 expression in THP1 cells), with moderate variations across the cell lines tested (1.5- to 3.5-fold).(d) Expression of ATG16L1 in human primary immune cells. In a resting human immune cell RNA panel (Clontech), ATG16L1 showed a clear peak of expression in the T cell compartment, with CD4+ and CD8+ cells expressing high levels of transcript (15- to 20-fold more than control samples). We detected modest levels of ATG16L1 in CD19+ cells and low levels in CD14+ monocytes and unfractionated mononuclear cells. In all cases, we performed real-time quantitative RT-PCR reactions in duplicate and plotted the means; error bars represent 1 s.d. We normalized expression levels by comparison with GAPDH controls and plotted arbitrary relative expression units, where the SW480 or placental RNA expression equals 1 (for cell lines or primary cells, respectively). We isolated all RNAs from resting cells in the absence of stimulation or activation.
figf3(a) We achieved specific siRNA knockdown of overexpressed, Flag-tagged ATG16L1 in HEK293 cells within 48 h of transfection with oligonucleotide duplexes. Flag-ATG16L1 was undetectable by protein blotting after treatment with specific siRNA constructs, but expression was maintained with control duplexes.(b) Endogenous ATG16L1 mRNA knockdown (mean relative abundance ± s.d.) by siRNA 2 in HeLa cells within 48 h of transfection, as assessed by real-time quantitative RT-PCR normalized to GAPDH. Compared with control duplex, siRNA 2 yielded an 89% reduction in transcripts. RT-PCR was performed in triplicate; results represent two independent experiments.c) Knockdown of ATG16L1 prevented effective autophagy of S. typhimurium in HeLa cells. Forty-eight hours after cotransfection with control siRNA or duplex 2 and LC3-GFP plasmid, HeLa cells were infected for 1 h with Salmonella typhimurium SL1344, fixed and examined microscopically. Mean percentages (± s.e.m.) of bacteria per cell encapsulated by LC3+ membranes (autophagosomes) are shown. Bacterial counts were pooled from two separate experiments; each counted a minimum of 100 infected cells. Significance was assessed by two-tailed Students t-test, assuming unequal variances.(d) Representative images of intracellular S. typhimurium show normal autophagic encapsulation by LC3+ membranes in control siRNA-treated cells but loss of autophagic targeting after ATG16L1 knockdown.
