    Figure 4: <t>TRAF6</t> is a direct downstream target of miR-146b-5p in HCC. A. The assumed miR-146b-5p binding sequences in the 3’-UTR of TRAF6. B. Wild-type miR-146b-5p crippled the luciferase activity that carried the 3’-UTR of TRAF6 mRNA. ***P<0.001. C-F. Alteration of miR-146b-5p levels regulated TRAF6 expression in vitro (C and D) and in vivo (E and F). The mRNA (C and E) and protein (D and F) expression levels of TRAF6 were down-regulated through miR-146b-5p over-expression and up-regulated by miR-146b- 5p knockdown. The mRNA levels were determined by qRT-PCR. The protein expression was detected by immunoblotting in vitro and IHC in vivo. **P<0.01. G. TRAF6 expression was lower in high miR-146b-5p group than that in low miR-146b-5p group. **P<0.01. All experiments were performed at least in triplicate and the data in B-G are presented as the (mean ± SD).

    Following exposure to TLR4 ligands or free fatty acids (FFA), TRAF6 interacts with ECSIT and NRDP1, and BNIP3 levels rise. TRAF6 localizes to the mitochondria where it complexes with Parkin and mediates the recruitment of ubiquitin receptors p62 and TAX1BP1. TRAF6 also restrains Parkin activity to support mitochondrial BNIP3 recruitment. Together, these events promote the induction of mitophagy to adaptively respond to metabolic stress and maintain β-cell function.

TRAF6 localizes to the mitochondria where it complexes with Parkin and mediates the recruitment of ubiquitin receptors p62 and TAX1BP1. TRAF6 also restrains Parkin activity to support mitochondrial BNIP3 recruitment. Together, these events promote the induction of mitophagy to adaptively respond to metabolic stress and maintain β-cell function.

    Curcumin inhibits RANKL-promoted osteoclast-related protein expression in OCPs. (A) After the intervention with different concentration of curcumin (0, 5, 10 or 15 μM), the protein expression levels of TRAF6, NFATc1 and DC-stamp in OCPs were detected using Western-Blot assays. The samples came from the same experiment, and different gels were processed in parallel. (B–D) The histogram displays the relative quantitative results of protein levels in A . (E) With RANKL intervention, OCPs were treated with or without curcumin for the indicated times in α-MEM with 1% FBS (appropriate starvation for enhancing the phosphorylation effect). p-ERK, p-JNK and p-P38 were detected using Western-Blot assays. The expression of phosphorylated proteins is represented by the ratio of phosphorylated protein to total protein.

    The Working model diagram of this study. In brief, RANKL binds to its receptor RANK, and then activates the autophagy of OCPs through downstream TRAF6 signaling. The signal transduction downstream of TRAF6 is as follows: after phosphorylation by upstream signaling molecules, activated JNK leads to BCL2 phosphorylation at S70, thereby causing Beclin1 to dissociate from the BCL2-Beclin1 complex, which leads to Beclin1-dependent autophagy, and the differentiation of OCPs into mature osteoclasts. Furthermore, free BCL2 from the BCL2-Beclin1 complex binds to Bax, thereby inhibiting Bax-dependent apoptosis, which is also a promoter of osteoclast differentiation. Curcumin can inhibit the formation of mature osteoclasts by inhibiting RANKL-RANK-TRAF6-JNK-BCL2-Beclin1-autophagy activation signal transduction.
