Network pharmacology analysis suggested that EF water extract not only regulated the proliferation and differentiation of osteoblasts but also caused a regulatory effect on osteoclasts via multiple signaling pathways, such as RANKL-RANK-induced signaling and TGF-β signaling. These findings indicate that the EF-TNT promotes differentiation and proliferation of osteoblasts, and represents considerable potential for use in clinical applications.Colorectal cancer (CRC) is one of the most common malignant tumors in the world. Cases of colon cancer have experienced dramatic growth for the past few decades in China, while the rate of rectal cancer descends 3% every year in the West. The purpose of this study is to reveal the potential impact of miR-21-5p on the occurrence process of CRC and its connection with a close homolog of L1 (CHL1). In this study, the expression level of the miR-151-3p was found to be significantly higher in colon adenocarcinoma tissue compared with adjacent normal tissues, while the CHL1 was lower in colon adenocarcinoma tissues. The expression of miR-151-3p was inversely correlated with the expression of CHL-1, as it was confirmed with correlation analysis. miR-151-3p deregulates the expression of CHL1. CHL1 overexpression can restrain the proliferation and invasion of CRC. Tumorigenesis experiments showed that the tumor growth rate of CHL1-OV was significantly reduced in mice, and its effect could be reversed by miR-151-3p mimics. Taken together, our study may provide new insights into the potential mechanisms of progression of CRC, and may provide a theory for targeted drug therapy.Liposome is a traditional drug-delivery system and most novel studies have focused on its drug release function. In this paper, a new drug-delivery system based on liposomes was prepared, which contains hydrophobic FeAg alloy nanoparticles (FeAgNPs) in their lipid bilayer and berberine as test drug in their middle water phase. The size of AgFe-Ls was about 200 nm, the encapsulation efficiency of drugs was 35% and the lower critical solution temperature (LCST) of AgFe-Ls was about 41.96 °C. FeAgNPs in the AgFe-Ls had a 11 iron-to-silver atomic ratio with both optical and superparamagnetic properties. STC-15 The photothermal effect and magnetocaloric effect of FeAgNPs could serve up both photo-stimulated and magnetic- stimulated drug release to liposomes. Release experiments results showed that AgFe-Ls could easily release berberine when stimulated by UV light (45% drug release at 20 min) or alternating current electromagnetic field (AMF) (80% drug release at 4 h). AgFe-Ls with both photo-controlled and magnetic-controlled drug release functions are promising to serve up chemotherapy drugs to cancer cells.The mitochondria have recently become a novel target in the treatment of cancer. Targeted delivery by nanoparticles (NPs) has shown potential in enhancing existing therapeutic principles. With toxicity remaining a recurring issue, the green synthesis of inorganic NPs and modification with polymers may help to improve stability and biocompatibility. We synthesized epigallocatechin gallate (EGCG)-capped gold NPs (AuNPs), and functionalized with poly-D-lysine grafted polyethylene glycol (PDL-g-PEG), and the mitochondrial targeting triphenylphosphonium cation, and thereafter assessed their mitochondrial delivery capacity of paclitaxel in cancer cells in vitro. This PDL-g-PEG coated EGCG-AuNPs were further assessed for their laminin receptor avidity and mitochondrial localisation potential, upon functionalisation with the delocalised cation, triphenylphosphine. The laminin receptor dependent uptake and mitochondrial localisation of targeted T-Au(PDL-g-PEG) NPs were confirmed by ICP-OES and fluorescent microscopy. Their delivery of paclitaxel to the mitochondria of cancer cells elicited significant cytotoxicity especially in the human cervical carcinoma (HeLa) cell line, compared to the untargeted T-Au(PDL-g-PEG) and free drugs. Mechanistic studies implicated caspase dependent apoptosis as the mechanism of cell death. Our findings demonstrate the capacity of T-Au-[PDL-PEG] NPs to preferentially localize in the tumour mitochondria, and confirms the potential impact of subcellular targeting, especially to the mitochondria in cancer cells for an improvement in the therapeutic indices of these drugs.Self-assembling peptide hydrogels have a high water content, good biocompatibility and have become a competitive research object in the fields of tissue engineering, cancer treatment and drug delivery. In our research, a hexapeptide with high pH sensitivity was designed and synthesized by utilizing a solid-phase synthesis method. Under physiological conditions, the peptide could self-assemble into a hydrogel. When it reached the tumor acidic microenvironment, the peptide was degraded and doxorubicin was released to exert its antitumor effect. A series of physicochemical properties were investigated, including gelling ability, secondary structure, micromorphology, rheological properties and drug release studies. The results illustrated that PIDO peptide hydrogel has good pH responsiveness and injectability. In vitro cytotoxicity experiments and in vivo antitumor experiments showed that PIDO peptide hydrogel has a highly effective therapeutic effect on tumor cells and is less toxic to normal tissues. Our research provides a promising option for targeted drug delivery and sustainable release.Cystic echinococcosis (CE) is a worldwide zoonotic disease. At present, the treatment options of CE are limited. The main drugs used in clinical chemotherapy of echinococcosis are albendazole and mebendazole, but they mainly exert longterm antiparasitic effects based on high doses. Therefore, there is an urgent need for effective and safe anti-CE drugs. Previous studies have identified harmine (HM) as a new anti-CE drug. In this study, the efficacy of harmine derivatives was evaluated in vitro and in vivo. The harmine derivatives were tested against E. granulosus protoscoleces (PSC) in vitro. The effect of harmine derivatives was time and concentration dependent at different concentrations, and the anti-CE effect was better than that of harmine. The mortality rate of PSC reached 100% on the 5th day after exposure to harmine derivatives at a concentration of 100 μmol · L -1. Compared with the untreated model control mice, the weight of the cyst was significantly reduced in infected mice treated with harmine derivatives.
