Fig. 5. Astragalin (AST) ameliorated lipopolysaccharide (LPS)-induced acute liver injury (ALI) in mice by inhibiting necroptosis. (A-B) Western blotting measured the protein levels of tumor necrosis factor (TNF)-α, TANK-binding kinase 1 (TBK1), receptor-interacting protein kinase 1 (RIPK1), RIPK3, mixed lineage kinase domain-like protein (MLKL), and TNFR1-associated death domain protein (TRADD). The relative expression levels were normalized to β-actin. Student’s t-test was performed, n = 3, * P < 0.05, ** P < 0.01, *** P < 0.001, ns denotes no significance. (C-D) AST decreased the number of P-RIPK3 positive cells that was increased by LPS treatment. Student’s t-test was performed, n = 6, *** P < 0.001.

1A) CFBE cells were transfected with GFP-wt CFTR, GFP-ΔF508 CFTR, GFP-TNR CFTR, or GFP-G551D CFTR. Forty-eight hours after transfection, cells were lysed, and co-immunoprecipitation was performed using either anti-TRADD or mouse IgG (immunoglobulin G) antibodies. CFTR expression in the total cell lysates is shown, as well as CFTR, which is co-precipitated with TRADD. The results show that TRADD binds to wt and G551D but not to ΔF508 and TNR CFTR, both of which remain in the ER, suggesting that TRADD binds only to CFTR that is processed to the plasma membrane. (1B-C) CFBE cells were transfected with GFP-wt CFTR (1B) or GFP-ΔF508 CFTR (1C). Antibodies recognizing GFP (green) and TRADD (red) were used in immunofluorescence-based detection. wt CFTR and TRADD were colocalized in the perinuclear region of the cells. Importantly, TRADD did not colocalize with ΔF508 CFTR, consistent with the lack of binding of this mutant. # - denotes that CFBE cells were transfected CFTR.

NF-κB was measured in CFBE cells transfected with either wt CFTR or ΔF508 CFTR, with and without knockdown (KD) of TRADD using shRNA. There was no difference in total NF-κB protein between the parental CFBE cells and those stably expressing wt CFTR (6A). In (6B) and summarized in (6C), transfection of wt CFTR into CFBE cells in TRADD-containing cells caused a reduction in NF-κB activity when compared to cells transfected with ΔF508 CFTR. The difference in nuclear NF-κB between wt and ΔF508 CFTR-expressing cells was less in cells in which TRADD levels were reduced by treatment with shRNA. Results are means ± S.E. (n=3). *, p<0.05.

CFBE cells were transfected with GFP-CAL. (2A). TRADD alone. (2B). Cal alone. (2C) is the merged image. Note that CAL colocalized with TRADD and bound to TRADD in co-immunoprecipitation experiments (2D). Since we have shown previously [28] that CAL is localized at the TGN and also binds CFTR via the PDZ domain, these data suggest that TRADD and wt CFTR colocalize in the TGN.

Parental CFBE cells and CFBE stably expressing wt CFTR were transfected with either TRADD or a control vector. (3A) CFTR was detected by Western blotting using an anti-CFTR monoclonal antibody. Note that there is much less endogenous CFTR in the untransfected CFBE cells compared to those stably expressing wt-CFTR. Thus, in this western blot containing wt-CFTR the endogenous ΔF508 CFTR is not evident. β-actin was used as a loading control. TRADD overexpression dramatically increased the expression of mature C-band of wt CFTR but had no effect on the immature B-band, nor did it rescue ΔF508 CFTR. (3B) Results are means ± S.E. *, p<0.05 versus the control. (n=3), Data was normalized to CFBE-WT CFTR TRADD transfected.

There was no difference in the total NF-κB protein in either the parental CFBE cells or those stably expressing wt CFTR (5A). In (5B) and summarized in (5C), NF-κB activity was measured with an NF-κB assay kit (see Methods) using an antibody against the p65 (RelA) NF-κB transcription factor subunit. The assay takes advantage of the process of activation of NF-κB. When activated, the IkB inhibitory subunit is degraded, allowing the transcription factor subunits of the complex to translocate to the nucleus [65]. In the assay, p65 reactivity was measured in the nuclear extracts by detecting the chemiluminescence of the sample using FujiFilm LAS-3000. Since there was no change in total NF-kB, the p65 reactivity was measured in the nuclear extract and compared across the experimental maneuvers. Results are normalized to control. Results are means ± S.E. (n=3). *, p<0.05. Transfection of TRADD increased NF-kB activity only in CFBE cells containing ΔF508 CFTR, and not in cells expressing wt CFTR. NF-κB was measured in CFBE cells and CFBE stably expressing wt CFTR with and without the transfection of additional TRADD.

When the lysosome is blocked the expression of TRADD protein is stable over the experimental period indicating that CFTR enhances the degradation of TRADD by the lysosome.

12A. TNFα forms a complex with TNFR, which binds to its obligate intracellular adaptor TRADD. The TRADD complex drives proinflammatory signaling by activating NFκB. Wt CFTR inhibits TRADD by inducing degradation to the lysosome. The result is suppression of NFκB activation. ShRNA against TRADD reduces TRADD and blocks TNFα-activated NFκB activation. Elevation of TRADD expression feeds back to elevate Wt CFTR. CFTRinh172 blocks channel activity by Wt CFTR, and blocks inhibitor of TRADD by Wt CFTR. Color code: red = activation; green = inhibition. 12B). In the presence of mutant ΔF508 CFTR, TRADD is not inhibited. TNFα/TNFR (R=receptor) can now bind to TRADD, and drive activation of NFκB. The “*” signs indicate “activation” of the TNFα/TNFR complex and the NFkB complexes, respectively.
