The Human antigen R protein (HuR) is an RNA-binding protein that recognizes U/AU-rich elements in diverse RNAs through two RNA-recognition motifs, RRM1 and RRM2, and post-transcriptionally regulates the fate of target RNAs. The natural product dihydrotanshinone-I (DHTS) prevents the association of HuR and target RNAs in vitro and in cultured cells by interfering with the binding of HuR to RNA. Here, we report the structural determinants of the interaction between DHTS and HuR and the impact of DHTS on HuR binding to target mRNAs transcriptome-wide. NMR titration and Molecular Dynamics simulation identified the residues within RRM1 and RRM2 responsible for the interaction between DHTS and HuR. RNA Electromobility Shifts and Alpha Screen Assays showed that DHTS interacts with HuR through the same binding regions as target RNAs, stabilizing HuR in a locked conformation that hampers RNA binding competitively. HuR ribonucleoprotein immunoprecipitation followed by microarray (RIP-chip) analysis showed that DHTS treatment of HeLa cells paradoxically enriched HuR binding to mRNAs with longer 3’UTR and with higher density of U/AU-rich elements, suggesting that DHTS inhibits the association of HuR to weaker target mRNAs. In vivo, DHTS potently inhibited xenograft tumor growth in a HuR-dependent model without systemic toxicity.

The plaques formed by amyloid-β (Aβ) accumulation and neurofibrillary tangles formed by hyper-phosphorylated tau protein are the 2 major pathologies of Alzheimer’s disease (AD). Recently, autophagy is considered to be a self-degradation process of preserved cytoplasmic abnormal substances, including Aβ and tau.

α-Screen assay is used to discover a new mammalian target of rapamycin (mTOR) signaling inhibitor, and laser scanning confocal microscopic analysis is used to investigate the autophagy formation. Lastly, ELISA and Western blot assays are used to identify the mTOR signaling inhibitor effect on Aβ and tau and the underlying mechanism.

In the current study, we discover that dihydrotanshinone I (DTS I), extracted from Radix Salviae, can obviously inhibit mTOR phosphorylation and increase autophagy via increasing AMPK phosphorylation. Further study demonstrates that DTS I increases Aβ clearance and decreases Tau phosphorylation through autophagy enhancement involved with AMPK/mTOR pathway.

Our study indicates that DTS I can increase Aβ clearance and decrease Tau phosphorylation via autophagy enhancing involved with AMPK/mTOR pathway, which highlights the therapeutic potential of DTS I for the treatment of AD.

Ulcerative colitis (UC) is a chronic and relapsing inflammatory disorder of the colon and rectum with increasing morbidity in recent years. 15,16-dihydrotanshinone Ӏ (DHT) is a natural product with multiple bioactivities. In this study, we aimed to investigate the protective effect and potential mechanisms of DHT on UC. Dextran sulfate sodium salt (DSS) was administrated in drinking water for 7 days to induce UC in mice. DHT (10 and 25 mg/kg) significantly alleviated DSS-induced body weight loss, disease activity index (DAI) scores, and improved histological alterations of colon tissues. DHT inhibited the myeloperoxidase (MPO) activity, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression in colon tissues and decreased serum levels of TNF-α, IL-1β, IL-6, and high-mobility group box 1 (HMGB1). Furthermore, increased expression of kinases receptor-interacting protein 1 (RIP1), RIP3, mixed lineage kinase domain-like protein (MLKL) and decreased expression of caspase-8 in colon tissues were partially restored by DHT. In LPS-stimulated RAW264.7 macrophages, DHT significantly inhibited generation of nitric oxide, IL-6, TNF-α and protein expression of iNOS, COX-2. In addition, increased expression of iNOS, COX-2, and phosphorylated RIP1, RIP3, MLKL in response to LPS plus Z-VAD (LZ) were also suppressed by DHT. DHT had no effect on TNF-α + BV6 + Z-VAD (TBZ) induced phosphorylation of RIPs and MLKL in HT29 cells. Especially, DHT showed no effect on LZ and TBZ-induced necroptosis in RAW264.7 and HT29 cells, respectively. In summary, DHT alleviated DSS-induced UC in mice by suppressing pro-inflammatory mediators and regulating RIPs-MLKL-caspase-8 axis.
