Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune disorder that can give rise to joint swelling and inflammation, potentially affecting the entire body, closely linked to the state of T cells. The T-cell activation Rho GTPase activating protein (TAGAP) is associated with many autoimmune diseases including RA and is directly linked to the differentiation of Th17 cells. The present study intends to investigate the influence of TAGAP on the RA progression and its mechanism to empower new treatments for RA. A collagen-induced-arthritis (CIA) rat model was constructed, as well as the extraction of CD4+ T cells. RT-qPCR, H&E staining and safranin O/fast green staining revealed that TAGAP interference reduced TAGAP production in the ankle joint of CIA rats, and joint inflammation and swelling were alleviated, which reveals that TAGAP interference reduces synovial inflammation and cartilage erosion in the rat ankle joint. Expression of inflammatory factors (TNF-α, IL-1β, and IL-17) revealed that TAGAP interference suppressed the inflammatory response. Expression of pro-inflammatory cytokines, matrix-degrading enzymes, and anti-inflammatory cytokines at the mRNA level was detected by RT-qPCR and revealed that TAGAP interference contributed to the remission of RA. Mechanistically, TAGAP interference caused a significant decrease in the levels of RhoA and NLRP3. Assessment of Th17/Treg levels by flow cytometry revealed that TAGAP promotes Th17 cells differentiation and inhibits Treg cells differentiation in vitro and in vivo. In conclusion, TAGAP interference may decrease the differentiation of Th17 cells by suppressing the expression of RhoA and NLRP3 to slow down the RA progression.

Abstract
Benefiting from the evolution of nanotechnology, the combination therapy by gene interference and reactive oxygen species (ROS) scavenging are expected, which holds great potential in inflammatory bowel disease (IBD) therapy. However, the functional integration of different therapeutic modules through interface modification of gene vectors for safe and efficient treatment is urgently needed. Herein, we present a catechol chemistry-mediated core-shell nanoplatform for ROS scavenging-mediated oxidative stress alleviation and siRNA-mediated gene interference in a dextran sulfate sodium (DSS)-induced colitis model. The nanoplatform is constructed by employing mesoporous polydopamine nanoparticles (MPDA NPs) with surface modification of amines as the porous core for TNF-α-siRNA loading (31 wt %) and exerts an antioxidant function, while PDA-induced biomineralization of the calcium phosphate (CaP) coating is used as the pH-sensitive protective shell to prevent siRNA from premature release. The CaP layer degraded under weakly acidic subcellular conditions (lysosomes); thus, the synergistic integration of catechol and cation moieties on the exposed surface of MPDA resulted in an efficient lysosomal escape. Subsequently, effective ROS scavenging caused by the electron-donating ability of MPDA and efficient knocking down (40.5%) of tumor necrosis factor-α (TNF-α) via sufficient cytosolic gene delivery resulted in a synergistic anti-inflammation therapeutic effect both in vitro and in vivo. This work establishes the first paradigm of synergistic therapy in IBD by ROS scavenging and gene interference.

Abstract
BACKGROUND Based on previous research indicating that pedunsaponin A (PA) can destroy the gills of Pomacea canaliculata, we chose the gill as the main research object, and identified the target protein of PA in the gills of P. canaliculata through proteomics and RNA interference (RNAi). RESULTS Proteomics showed that 180 proteins were downregulated after PA treatment in P. canaliculata. Among them, we chose advillin (PcAdv), receptor type tyrosine protein phosphatase (PcRT) and unconventional myosin heavy chain 6 (PcUM) as candidate target proteins through bioinformatics analysis. The small interfering RNA (siRNA) with the best interference effect was identified through further screening. Gene interference rates were 97%, 98% and 82% for PcAdv, PcRT and PcUM, respectively. The results showed that after RNAi treatment, the mortality of P. canaliculata treated with PcAdv (60.0%) was significantly lower than that for the control (93.3%); histological analysis showed that the structure of the gill was intact, cilia shedding was reduced, and the survival rate of hemocytes had increased. CONCLUSION These findings indicate that, when the protein was absent or suppressed, the channel for entry of PA into the hemocytes of P. canaliculata was blocked, which reduced PA binding to hemocytes, and that there is a close relationship between shedding of gill cilia and PA entry into hemocytes. PcAdv is thus the key protein in PA destruction of gill cilia. Locating the proteins in gills that interact with drugs and investigating their mode of action is of great importance in the development of new molluscicides to control P. canaliculata populations.

Abstract
The in situ generation of siRNAs in living cells can greatly enhance the specificity and efficiency of gene therapy. Inspired by the natural molecular machines that organize different compartments sequentially in a limited space to facilitate cellular process, this work constructs a DNA nanomachine (DNM) by alternately hybridizing two pairs of DNA/RNA hybrids to a DNA scaffold generated by rolling circle amplification for highly efficient in situ siRNA assembly in living cells. After target cell-specific delivery of DNM, intracellular specific microRNA can work as a trigger to operate the DNM by initiating DNA cascade displacement reaction between DNA/RNA hybrids along the scaffold for continuous generation of siRNAs. Using miR-21 as a model, efficient siRNAs generation is achieved via DNA templated cascade reaction, which demonstrated impressive suppressions to VEGF mRNA and protein expressions in cells and in vivo tumor growth and indicated promising application of the designed strategy in gene therapy.

Abstract
Gene interference-based therapeutics represent a fascinating challenge and show enormous potential for cancer treatment, in which microRNA is used to correct abnormal gene. On the basis of the above, we introduced microRNA-31 to bind to 3'-untranslated region of mtEF4, resulting in the downregulation of its messenger RNA and protein to trigger cancer cells apoptosis through mitochondria-related pathway. To achieve better therapeutic effect, a mesoporous silica nanoparticle-based controlled nanoplatform had been developed. This system was fabricated by conjugation of microRNA-31 onto doxorubicin-loaded mesoporous silica nanoparticles with a poly(ethyleneimine)/hyaluronic acid coating, and drug release was triggered by acidic environment of tumors. By feat of surface functionalization and tumor-specific conjugation to nanoparticles, our drug delivery system could promote intracellular accumulation of drugs via the active transport at tumor site. More importantly, microRNA-31 not only directly targeted to mtEF4 to promote cell's death, but had synergistic effects when used in combination with doxorubicin, and achieved excellent superadditive effects. As such, our research might provide new insights toward detecting high mtEF4 cancer and exploiting highly effective anticancer drugs.
