Abstract
Small interfering RNA (siRNA)-based gene therapy represents a promising strategy for tumor treatment. Novel gene vectors that can achieve targeted delivery of siRNA to the tumor cells without causing any side effects are urgently needed. To this end, the large amino acid mimicking carbon dots with guanidinium functionalization (LAAM GUA-CDs) are designed and synthesized by choosing arginine and dopamine hydrochloride as precursors. LAAM GUA-CDs can load siRNA through the multiple hydrogen bonds between their guanidinium groups and phosphate groups in siRNA. Meanwhile, the amino acid groups at the edges of LAAM GUA-CDs endow them the capacity to target tumors. After loading siBcl-2 as a therapeutic agent, LAAM GUA-CDs/siBcl-2 has a high tumor inhibition rate of up to 68%, which is twice more than that of commercial Lipofectamine 2000. Furthermore, LAAM GUA-CDs do not cause side effect during antitumor treatment owing to their high tumor-targeting ability, thus providing a versatile strategy for tumor-targeted siRNA delivery and cancer therapy.

Abstract
Newcastle disease virus is paramyxoviridae, Avian mumps virus genus type I, and infects more than 250 species of birds, causing huge losses on poultry farming worldwide. Numerous experiments have demonstrated that Newcastle disease virus has oncolytic activity on tumor cells and can selectively replicate in cancer cells. Thus, Newcastle disease virus is a potential therapeutic agent for cancer treatment. Some human clinical trials achieved good results. In this review, we summarized research progress of the relationship between the structural protein of Newcastle disease virus and virulence, anti-tumor and autophagy of Newcastle disease.

Abstract
Nucleic acid-based therapy has emerged as a revolutionary methodology for treatment of the diseases related to protein dysfunction; however, lack of systemically applicable synthetic delivery systems limits its current usage in local applications, particularly for DNA-based therapy with regard to the poor bioavailability in the systemic administrations. To overcome this obstacle, we compiled multiple chemistry-based strategies into the manufacture of the gene delivery formulations to pursue improved tolerability of DNA to the enzymatic degradation in the biological milieu and prolonged retention in the systemic circulation. Here, we constructed a distinctive multilayered functional architecture: plasmid DNA (pDNA) was electrostatically complexed with cationic poly(lysine) (polyplex) as the interior pDNA reservoir, which was further cross-linked by redox-responsive disulfide cross-linking to minimize the occurrence of polyplex disassembly through exchange reaction with the biological charged components. Still, the pDNA reservoir was spatially protected by a sequential thermoresponsive poly(N-isopropylacrylamide) palisade as the intermediate barrier and a biocompatible hydrophilic poly(ethylene glycol) (PEG) shell with the aim of preventing the accessibility of the biological species, particularly the nuclease degradation to the pDNA payload. Subsequent investigations validated the utilities of these strategies in accomplishing prolonged blood retention. In an attempt to apply this method for tumor therapy, ligand cyclic (Arg-Gly-Asp) peptide was attached at the distal end of PEG, validating prompted tumor-targeted delivery and gene expression of the loaded antiangiogenic gene at the targeted tumor cells and accordingly exerting antiangiogenesis of the tumors for abrogation of tumor growth. Together with its excellent safe profile, the proposed formulation suggests potential utility as a practical gene delivery system for treatment of intractable diseases.

Abstract
Oncolytic viruses have recently received widespread attention for their potential in innovative cancer therapy. Many telomerase promoter-regulated oncolytic adenoviral vectors retain E1A and E1B. However, the functions of E1A and E1B proteins in the oncolytic role of replication-competent adenovirus (RCAd) and RCAd enhanced transduction of replication defective adenoviruses (RDAd) have not been addressed well. In this study, we constructed viruses expressing E1A alone, E1A plus E1B-19 kDa, and E1A plus E1B-19 kDa/55 kDa. We then tested their roles in oncolysis and replication of RCAd as well as their roles in RCAd enhanced transfection rate and transgene expression of RDAd in various cancer cells in vitro and in xenografted human NCI-H460 tumors in nude mice. We demonstrated that RCAds expressing E1A alone and plus E1B-19 kDa exhibited an obvious ability in replication and oncolytic effects as well as enhanced RDAd replication and transgene expression, with the former showed more effective oncolysis, while the latter exhibited superior viral replication and transgene promotion activity. However, RCAd expressing both E1A and E1B-19 kDa/55 kDa was clearly worst in all these abilities. The effects of E1A and E1B observed through using RCAd were further validated by using plasmids expressing E1A alone, E1A plus E1B-19 kDa, and E1A plus E1B-19 kDa/55 kDa proteins. Our study provided evidence that E1A was essential for inducing replication and oncolytic effects of RCAd as well as RCAd enhanced RDAd transduction, and expression of E1B-19 kDa other than E1B-55 kDa could promote these effects. E1B-55 kDa is not necessary for the oncolytic effects of adenoviruses and somehow inhibits RCAd-mediated RDAd replication and transgene expression.
