In this study, we prepared PTX-loaded mesoporous hollow SnO2 nanofibers conjugated with folic acid (SFNFP) for liver cancer therapy. According to SEM and TEM characterization, SFNF showed a mesoporous hollow structure. The average outer diameter was 200 nm, and the wall thickness was 50 nm. The DSC and XRD study showed that PTX in the channels of nanofibers was present in an amorphous state. The in vitro release experiments demonstrated that SFNF could efficiently improve the dissolution rate of PTX. Both in vitro cell experiments and in vivo antitumor experiments showed that SFNFP could efficiently inhibit the growth of liver cancer cells. Therefore, SFNF is a promising targeting antitumor drug delivery carrier.

Abstract An enzyme-responsive colon-specific delivery system was developed based on hollow mesoporous silica spheres (HMSS) to which biodegradable chitosan (CS) was attached via cleavable azo bonds (HMSS-N=N-CS). Doxorubicin (DOX) was encapsulated in a noncrystalline state in the hollow cavity and mesopores of HMSS with the high loading amount of 35.2%. In vitro drug release proved that HMSS-N=N-CS/DOX performed enzyme-responsive drug release. The grafted CS could increase the biocompatibility and stability, and reduce the protein adsorption on HMSS. Gastrointestinal mucosa irritation and cell cytotoxicity results indicated the good biocompatibility of HMSS and HMSS-N=N-CS. Cellular uptake results indicated that the uptake of DOX was obviously increased after HMSS-N=N-CS/DOX was preincubated with a colonic enzyme mixture. HMSS-N=N-CS/DOX incubated with colon enzymes showed increased cytotoxicity, and its IC 50 value was three times lower than that of HMSS-N=N-CS/DOX group without colon enzymes. The present work lays the foundation for subsequent research on mesoporous carriers for oral colon-specific drug delivery.

Novel Target

Hepatocellular carcinoma (HCC), the most common primary liver cancer, is challenging to treat due to its typical late diagnosis, mostly at an advanced stage. Therefore, there is a particular need for research in diagnostic and prognostic biomarkers and therapeutic targets for HCC. The use of long noncoding (lnc) RNAs can widen the list of novel molecular targets improving cancer therapy. In hepatocarcinogenesis, the role of the lncRNA H19, which has been known for more than 30 years now, is still controversially discussed. H19 was described to work either as a tumor suppressor in vitro and in vivo, or to have oncogenic features. This review attempts to survey the conflicting study results and tries to elucidate the potential reasons for the contrary findings, i.e., different methods, models, or readout parameters. This review encompasses in vitro and in vivo models as well as studies on human patient samples. Although the function of H19 in HCC remains elusive, a short outlook summarizes some ideas of using the H19 locus as a novel target for liver cancer therapy.

Anticancer Activities

Background: Cancer is defined as an abnormal/uncontrolled cell growth that shows rapid cell division. This disease is annually recognized in more than ten million people. Nanomaterials can be used as new strategies for cancer therapy. Nanostructured devices have developed for drug delivery and controlled release and created novel anticancer chemotherapies. Nanomaterials were taken into consideration because of their new properties, containing a large specific surface area and high reactivity. Copper oxide nanoparticles (CuONPs) have potential applications in many fields like heterogeneous catalysis, antibacterial, anticancer, antioxidant, antifungal, antiviral, imaging agents, and drug delivery agents in biomedicine. CuONPs display different physical properties, such as hightemperature superconductivity, electron correlation effects, and spin dynamics. NPs can be synthesized using different methods like physical, chemical, and biological methods. Methods: Copper oxide nanoparticles (CuONPs) have been suggested for its broad usage in biomedical applications. In this review, we tried to exhibit the results of significant anticancer activity of green synthesized CuONPs and their characterization by different analytical techniques such as UV-Vis, FT-IR, XRD, EDAX, DLS, SEM, and TEM. Results: The green method for the synthesis of CuO nanoparticles as eco-friendly, cost-effective, and facile method is the more effective method. Synthesized CuONPs from this method have an appropriate size and shape. The Green synthesized CuONPs exhibited high potential against several breast cancer (AMJ-13, MCF-7, and HBL-100 cell lines), cervical cancer (HeLa), colon cancer (HCT-116), gastric cancer (human adenocarcinoma AGS cell line), lung cancer (A549), leukemia cancer, and other cancers with the main toxicity approach of increasing ROS production. Conclusion: The present review confirms the importance of green synthesized CuO nanoparticles in medical science especially cancer therapy that exhibited high activity against different cancer in both in vitro and in vivo. The main toxicity approach of CuONPs is increasing the production of reactive oxygen species (ROS). It needs to perform more studies about in vivo cancer therapy and following clinical trial testing in the future. We believe that green synthesized CuO nanoparticles can be used for the improvement of different diseases.
