In this study, amphiphilic block copolymer mPEG-cholic acid was synthesized in conjunction with TPGS as stabilizer to prepare multifunctional micelles. The formed polymeric micelles (PCTm) were used for the delivery of paclitaxel (PTX) and bufalin (BF). PEG group could enhance solubility and extend circulation time, while cholic acid groups achieved the liver targeted function. Combinations of these approaches could realize a synergistic therapeutic effect in the treatment of advanced hepatocellular carcinoma. CLSM in vitro results demonstrated that drug capsulation into PCTm could enhance cellular uptake. FCM results confirmed the uptake amount of C₆/PCTm was 7.5-fold higher than that of free C₆ after incubation for 2 h. Competitive inhibition test proved the Na⁺-taurocholate co-transporting polypeptide (NTCP) involved in the uptake mechanism of PCTm. Meanwhile, in vivo imaging assays demonstrated that the fluorescence intensity of Cy5.5/PCTm was higher than that of free Cy5.5 on liver and tumor with extended circulation time to 48 h. In addition, in vivo studies confirmed that the combined therapy exhibited the strongest tumor inhibition rate of 82.29% with lower systemic toxicity. Hence, these results indicated that PCTm could provide a promising strategy for targeting hepatocellular carcinoma and achieve the goal of synergism and attenuation.

And the article was included in Journal of Colloid and Interface Science in 2021.Recommanded Product: 38215-36-0 The following contents are mentioned in the article:

The micro-volume anal. and specific detection are both essential requirements in the field of chem. sensing and biol. testing. Membrane prefiltration can be used to improve the selectivity and accuracy of detection. But for traditional porous membrane filtration, it is difficult to achieve the transmembrane transport of micro-volume liquid due to the influence of lateral diffusion on membrane surface. Herein, we studied the focused transmembrane transport of micro-volume liquid in the porous polyethersulfone membrane with asym. (Janus) surface wettability. The hydrophilic layer (polydopamine) and hydrophobic layer (fluoropolymer) were deposited with controllable thickness by dip-coating and roller-assisted liquid printing. The micro-volume liquid focusing effect was verified by experiments such as visual wetting circle and fluorescent tracer. The liquid focusing effect of as-prepared Janus membrane was integrated with glucose test strip in the application of micro-volume liquid biosensing. Compared with conventional porous membrane, detected signal amplitude and response time were improved 7.5x and 2.7x, resp. In summary, this research studied the dynamics of liquid transport through Janus membrane and provides a new strategy for microfluidic detection applications through balancing detection volume, time and selectivity by the advantage of micro-volume liquid focusing effect.

Hepatocellular carcinoma (HCC) is one of the most common cancers. MicroRNA has been studied more and more deeply and may become a new target for the treatment of HCC. Here, we investigated the role of miR-455-3p in HCC progression. Compared with non-tumor tissues and normal human hepatic cells, miR-455-3p expression was significantly downregulated in HCC tissues and cell lines. And overexpression of miR-455-3p inhibited cell proliferation and migration but promoted cell apoptosis in HCC cell lines HepG2 and Huh7. Mechanism studies displayed that miR-455-3p targeted HDAC2 and neg. regulated HDAC2 expression. Moreover, HDAC2 was highly expressed in HCC tissues and cell lines. Overexpression of HDAC2 reversed the inhibitory effects of miR-455-3p on cell proliferation, migration and cell cycle protein (CDK6 and cyclin D1) expression, and neutralized the promotion effects of miR-455-3p on cell apoptosis and the activation of p53 pathway. Furthermore, a p53 inhibitor Pifithrin-α (PFT-α) effectively abolished the effects of miR-455-3p on HCC cell behaviors. Addnl., the role of miR-455-3p in tumorigenesis was evaluated by using a mouse xenograft model, and the data showed that miR-455-3p suppressed tumor growth in vivo. In summary, our results suggested that miR-455-3p targeted HDAC2 to inhibit cell proliferation, migration and promote cell apoptosis via the activation of p53 pathway.

JK184 can specially inhibit Gli in the Hedgehog (Hh) pathway, which showed great promise for cancer therapeutics. For developing aqueous formulation and improving anti-tumor activity of JK184, we prepared JK184 encapsulated MPEG-PCL micelles by the solid dispersion method without using surfactants or toxic organic solvents. The cytotoxicity and cellular uptake of JK184 micelles were both increased compared with the free drug. JK184 micelles induced more apoptosis and blocked proliferation of Panc-1 and BxPC-3 tumor cells. In addition, JK184 micelles exerted a sustained in vitro release behavior and had a stronger inhibitory effect on proliferation, migration and invasion of HUVECs than free JK184. Furthermore, JK184 micelles had stronger tumor growth inhibiting effects in s.c. Panc-1 and BxPC-3 tumor models. Histol. anal. showed that JK184 micelles improved anti-tumor activity by inducing more apoptosis, decreasing microvessel d. and reducing expression of CD31, Ki67, and VEGF in tumor tissues. JK184 micelles showed a stronger inhibition of Gli expression in Hh signaling, which played an important role in pancreatic carcinoma. Furthermore, circulation time of JK184 in blood was prolonged after entrapment in polymeric micelles. Our results suggested that JK184 micelles are a promising drug candidate for treating pancreatic tumors with a highly inhibitory effect on Hh activity.

High COX-2 expression contributes to a poor prognosis through the inhibition of chemotherapy-induced senescence in nasopharyngeal carcinoma was written by Shi, Chen;Guan, Yongjun;Zeng, Liang;Liu, Guizhu;Zhu, Yinghong;Xu, He;Lu, Yichen;Liu, Jiabin;Guo, Jiaojiao;Feng, Xiangling;Zhao, Xinying;Jiang, Weihong;Li, Guancheng;Li, Guiyuan;Dai, Yun;Jin, Fengyan;Li, Wei;Zhou, Wen.

Resistance to radiotherapy and chemotherapy currently represents one of the major reasons for therapeutic failure in nasopharyngeal carcinoma (NPC). However, the mechanisms underlying resistance to chemotherapy in NPC remain unclear. In this study, cell counting assay, cell cycle assay and senescence associated β-galactosidase activity were performed to evaluate cell growth, proliferation and senescence, resp. We found that the aberrant expression of cyclooxygenase-2 (COX-2) was associated with a poor outcome and recurrance in patients with NPC. In NPC cells, COX-2 overexpression increased cell proliferation, inhibited cellular senescence and resulted in chemoresistance, while the knockdown of COX-2 reduced cell proliferation, promoted cellular senescence and overcame chemoresistance. Furthermore, fibroblasts from COX-2 knockout mice exhibited cellular senescence, particularly when treated with chemotherapeutic agents. Mechanistically, COX-2 interacted with p53 protein and inhibited cellular senescence, which resulted in chemotherapeutic resistance. On the whole, these findings indicate that COX-2 may play a critical role in chemotherapeutic resistance in NPC via the inhibition of chemotherapy-induced senescence via the inactivation of p53. This study provides exptl. evidence for the preclin. value of increasing chemotherapy-induced senescence by targeting COX-2 as an effective antitumor treatment in patients with recurrent NPC.

MEHP/ethanol co-exposure favors the death of steatotic hepatocytes, possibly through CYP4A and ADH involvement was written by Tete, Arnaud;Gallais, Isabelle;Imran, Muhammad;Legoff, Louis;Martin-Chouly, Corinne;Sparfel, Lydie;Bescher, Maelle;Sergent, Odile;Podechard, Normand;Lagadic-Gossmann, Dominique. And the article was included in Food and Chemical Toxicology in 2020.Electric Literature of C16H19BrN2OS The following contents are mentioned in the article:

Liver steatosis has been associated with various etiol. factors (obesity, alc., environmental contaminants). How those factors work together to induce steatosis progression is still scarcely evaluated. Here, we tested whether phthalates could potentiate death of steatotic hepatocytes when combined with ethanol. Pre-steatotic WIF-B9 hepatocytes were co-exposed to mono (2-ethylhexyl) (MEHP, 500 nM; main metabolite of di (2-ethylhexyl) phthalate or DEHP) and ethanol (5 mM) for 5 days. An increased apoptotic death was detected, involving a DNA damage response. Using 4-Methypyrazole to inhibit ethanol metabolism, and CH-223191 to antagonize the AhR receptor, we found that an AhR-dependent increase in alc. dehydrogenase (ADH) activity was essential for cell death upon MEHP/ethanol co-exposure. Toxicity was also prevented by HET0016 to inhibit the cytochrome P 450 4A (CYP4A). Using the antioxidant thiourea, a role for oxidative stress was uncovered, notably triggering DNA damage. Finally, co-exposing the in vivo steatosis model of high fat diet (HFD)-zebrafish larvae to DEHP (2.56 nM)/ethanol (43 mM), induced the pathol. progression of liver steatosis alongside an increased Cyp4t8 (human CYP4A homolog) mRNA expression. Altogether, these results further emphasized the deleterious impact of co-exposures to ethanol/environmental pollutant towards steatosis pathol. progression, and unraveled a key role for ADH and CYP4A in such effects.

This work pledge to extend the therapeutic windows of hybrid nanoparticulate systems by engineering mannose-decorated hybrid nanoparticles based on poly lactic-co-glycolic acid (PLGA) and vegetable oil for efficient delivery of two lipophilic anti-inflammatory therapeutics (Celecoxib-CL and Indomethacin-IMC) to macrophages. The mannose surface modification of nanoparticles is achieved via O-palmitoyl-mannose spacer during the emulsification and nanoparticles assembly process. The impact of targeting motif on the hydrodynamic features (RH, PdI), stability (ζ-potential), drug encapsulation efficiency (DEE) is thoroughly investigated. Besides, the in vitro biocompatibility (MTT, LDH) and susceptibility of mannose-decorated formulations to macrophage as well their immunomodulatory activity (ELISA) are also evaluated. The monomodal distributed mannose-decorated nanoparticles are in the range of nanometric size (RH < 115 nm) with PdI < 0.20 and good encapsulation efficiency (DEE = 46.15% for CL and 76.20% for IMC). The quant. investigation of macrophage uptake shows a 2-fold increase in fluorescence (RFU) of cells treated with mannose-decorated formulations as compared to non-decorated ones (p < 0.001) suggesting an enhanced cell uptake resp. improved macrophage targeting while the results of ELISA experiments suggest the potential immunomodulatory properties of the designed mannose-decorated hybrid formulations.

The mol. basis of anticancer and apoptotic effects of R-goniothalamin (GON), a plant secondary metabolite was studied. We show that induction of oxidative stress and reactivation of mutant p53 underlie the strong cytotoxic effects of GON against the breast cancer cells. Flow cytometry and other pertinent assays showed that GON-induced abundant reactive oxygen species (ROS), glutathione depletion, protein glutathionylation and activation of apoptotic markers. GON was found to conjugate with glutathione both in vitro and in cells and the product was characterized by mass spectrometry. We hypothesized that the redox imbalance induced by GON may affect the structure of the R175H mutant p53 protein, and account for greater cytotoxicity. Using the SKBR3 breast cancer and p53-null H1299 lung cancer cells stably expressing the R175H p53 mutant protein, we demonstrated that GON triggers the appearance of a wild-type-like p53 protein by using conformation-specific antibodies, immunoprecipitation, DNA-binding assays and target gene expression. p53 restoration was associated with a G2/M arrest, senescence, reduced cell migration, invasion and increased cell death. In SKBR3 xenografts developed in nude mice, there was a marked tumor growth delay by GON alone and GON + cisplatin combination. Our studies highlight the impact of tumor redox-stress generated by GON in activating the mutant p53 protein for greater antitumor efficacy.

Marine ascidian is becoming one of the main sources of an antitumor drug that has shown high bioactivity and extensive application in cancer treatment. Halocynthia roretzi, an edible marine sea squirt, has been demonstrated to have various kinds of biol. activities, such as anti-diabetic, anti-hypertension, and enhancing immunity. In this study, we reported that aqueous extracts from the edible parts of H. roretzi presented significantly inhibiting the efficiency on HepG-2 cell viability. The sep. mixed compound exhibited strong effects of inhibitory proliferation and induced apoptosis via the generation of ROS along with the concurrent loss of mitochondrial membrane potential on tumor cells. Furthermore, we found that there existed a significantly synergistic effect of the ascidian-extracted compound mixture with the anti-cancer drug doxorubicin. In the presence of the extracts from H. roretzi, the dose of doxorubicin at the cellular level could be reduced by a half dose. The extracts were further divided by semipreparative-HPLC and the active ingredients were identified as a mixture of fatty amide, which was composed of hexadecanamide, stearamide, and erucamide by UHPLC-MS/MS.

Multifunctional Immunoliposomes Enhance the Immunotherapeutic Effects of PD-L1 Antibodies against Melanoma by Reprogramming Immunosuppressive Tumor Microenvironment was written by Yu, Hei;Chen, Yang;Li, Qian;Mei, Zi;Pan, Jijia;Zhang, Siqi;Xiong, Chunyang;Su, Xiaodong;Wei, Shicheng. And the article was included in Small in 2022.Recommanded Product: 38215-36-0 The following contents are mentioned in the article:

The immunosuppressive tumor microenvironment (TME) can significantly limit the immunotherapeutic effects of the PD-L1 antibody (aPDL1) by inhibiting the infiltration of CD8+ cytotoxic T cells (CTLs) into the tumor tissues. However, how to reprogram the immunosuppressive TME and promote the infiltration of CTLs remains a huge challenge for aPDL1 to achieve the maximum benefits. Herein, the authors design a multifunctional immunoliposome that encapsulates the adrenergic receptor blocker carvedilol (CAR) and connects the dont eat me signal antibody (aCD47) and aPDL1 in series via a reactive oxygen species (ROS)-sensitive linker on the surface. In ROS-enriched immunosuppressive TME, the multifunctional immunoliposome (CAR@aCD47/aPDL1-SSL) can first release the outer aCD47 to block the do not eat me pathway, promote the phagocytosis of tumor cells by phagocytic cells, and activate CTLs. Then, the aPDL1 on the liposome surface is exposed to block the PD-1/PD-L1 signaling pathway, thereby inducing CTLs to kill tumor cells. CAR encapsulated in CAR@aCD47/aPDL1-SSL can block the adrenergic nerves in the tumor tissues and reduce their densities, thereby inhibiting angiogenesis in the tumor tissues and reprogramming the immunosuppressive TME. CARaCD47/aPDL1-SSL holds an effective way to reprogram the immunosuppressive TME and significantly enhance immunotherapeutic efficiency of aPDL1 against the primary cancer and metastasis.
