Abstract
Pancreatic cancer, predominantly pancreatic ductal adenocarcinoma (PDAC), remains a highly lethal malignancy with limited therapeutic options and a dismal prognosis. By targeting the underlying molecular abnormalities responsible for PDAC development and progression, gene therapy offers a promising strategy to overcome the challenges posed by conventional radiotherapy and chemotherapy. This study sought to explore the therapeutic potential of small activating RNAs (saRNAs) specifically targeting the CCAAT/enhancer-binding protein alpha (CEBPA) gene in PDAC. To overcome the challenges associated with saRNA delivery, tetrahedral framework nucleic acids (tFNAs) were rationally engineered as nanocarriers. These tFNAs were further functionalized with a truncated transferrin receptor aptamer (tTR14) to enhance targeting specificity for PDAC cells. The constructed tFNA-based saRNA formulation demonstrated exceptional stability, efficient saRNA release ability, substantial cellular uptake, biocompatibility, and nontoxicity. In vitro experiments revealed successful intracellular delivery of CEBPA-saRNA utilizing tTR14-decorated tFNA nanocarriers, resulting in significant activation of tumor suppressor genes, namely, CEBPA and its downstream effector P21, leading to notable inhibition of PDAC cell proliferation. Moreover, in a mouse model of PDAC, the tTR14-decorated tFNA-mediated delivery of CEBPA-saRNA effectively upregulated the expression of the CEBPA and P21 genes, consequently suppressing tumor growth. These compelling findings highlight the potential utility of saRNA delivered via a designed tFNA nanocarrier to induce the activation of tumor suppressor genes as an innovative therapeutic approach for PDAC.

Abstract
Despite advancements in the treatment of pulmonary cancer, the existence of mucosal barriers in lung still hampered the penetration and diffusion of therapeutic agents and greatly limited the therapeutic benefits. In this work, we reported a novel inhalable pH-responsive tetrahedral DNA nanomachines with simultaneous delivery of immunomodulatory CpG oligonucleotide and PD-L1-targeting antagonistic DNA aptamer (CP@TDN) for efficient treatment of pulmonary metastatic cancer. By precisely controlling the ratios of CpG and PD-L1 aptamer, the obtained CP@TDN could specifically release PD-L1 aptamer to block PD-1/PD-L1 immune checkpoint axis in acidic tumor microenvironment, followed by endocytosis by antigen-presenting cells to generate anti-tumor immune activation and secretion of anti-tumor cytokines. Moreover, inhalation delivery of CP@TDN showed highly-efficient lung deposition with greatly enhanced intratumoral accumulation, ascribing to the DNA tetrahedron-mediated penetration of pulmonary mucosa. Resultantly, CP@TDN could significantly inhibit the growth of metastatic orthotopic lung tumors via the induction of robust antitumor responses. Therefore, our work presents an attractive approach by virtue of biocompatible DNA tetrahedron as the inhalation delivery system for effective treatment of metastatic lung cancer.

Abstract
Copper is vital for various life processes, whereas severely toxic at excess level. Intracellular copper homeostasis is strictly controlled by a set of transporters and chaperones encoded by the copper homeostasis genes. Increasing evidence has shown that copper is usually overloaded in multiple malignancies, including pancreatic cancer, which has an extremely poor prognosis. Recently, silencing the SLC31A1 gene, which encodes a major transmembrane copper transporter (CTR1), has been demonstrated to be an effective means for reducing the malignant degree of pancreatic cancer by downregulating the cellular copper levels. Herein, we utilized tetrahedral framework nucleic acids (tFNAs) as vehicles to overcome the biological barriers for delivering small molecular RNAs and efficiently transferred two kinds of CTR1 mRNA-targeted RNA therapeutics, siCTR1 or miR-124, into PANC-1 cells. Both therapeutic tFNAs, termed t-siCTR1 and t-miR-124, prevented copper intake more effective than the free RNA therapeutics via efficiently suppressing the expression of CTR1, thereby significantly attenuating the progression of PANC-1 cells. In this study, therapeutic tFNAs are constructed to target metal ion transporters for the first time, which may provide an effective strategy for future treatment of other metal metabolism disorders.
