Abstract
Because of the complexity of cancer ecosystems, the efficacy of single-agent chemotherapy is limited. Herein, we report the use of cationic nanoparticles (designated PPCNs) generated from a chemically modified form of the chemotherapeutic agent podophyllotoxin (PPT) to deliver both microRNA-424 (miR-424) and PPT to tumor cells, thus combining chemotherapy and gene therapy. We evaluated the optimal loading ratio of miR-424─which targets programmed cell death ligand 1 (PD-L1) mRNA and reduces PD-L1 production, thus promoting the attack of tumor cells by T cells─for effective delivery of miR-424 and PPCNs into nonsmall-cell lung cancer cells (H460). Because miR-424 can reverse chemotherapy resistance, treatment of the tumor cells with the combination of miR-424 and PPT enhanced their sensitivity to PPT. Because miR-424 and the PPCNs regulated PD-L1 production in different ways, the miR-424@PPCN complexes were significantly more efficacious than either miR-424 or PPCNs alone. We also demonstrated that treatment of tumor-bearing mice with these complexes significantly inhibited tumor growth and extended survival. Moreover, additional in vitro experiments revealed that the complexes could remodel the tumor immune microenvironment, relieve immunosuppression, and achieve immune normalization. This novel system for delivering a combination of PPT and miR-424 shows great potential for the multimodal treatment of lung cancer.

Abstract
Low drug delivery efficiency elevates the cost of medication, lowers the therapeutic efficacy, and appears as a leading reason for unmet needs in anticancer therapies. Herein, we report the development of self-assembled podophyllotoxin-loaded lipid bilayer nanoparticles that inhibit the production of programmed cell death ligand 1 in lung cancer cells and promote tumor-specific immune responses, thus offering a strategy for regulating the immunosuppressive microenvironment of tumors. In addition, encapsulation of podophyllotoxin in the nanoparticles reduced its systemic toxicity, enhanced its penetration into tumors, and increased its antitumor efficacy. Systemic injection of the nanoparticles into tumor-bearing mice not only prevented tumor immune escape but also significantly inhibited tumor growth and extended survival. In general, the podophyllotoxin-loaded nanoparticles exhibited both immunological effects and antitumor effects in addition to having better targeting activity and fewer side effects than free podophyllotoxin. We expect our findings to facilitate the development of therapies for lung cancer.

Abstract
Podophyllotoxin (PTOX) is a biologically active compound derived from the podophyllum plant, and both it and its derivatives possess excellent antitumor activity. The PTOX derivatives etoposide (VP-16) and teniposide (VM-26) have been approved by the U.S. Food and Drug Administration (FDA) for cancer treatment, but are far from perfect. Hence, numerous PTOX derivatives have been developed to address the major limitations of PTOX, such as systemic toxicity, drug resistance, and low bioavailability. Regarding their anticancer mechanism, extensive studies have revealed that PTOX derivatives can induce cell cycle G2/M arrest and DNA/RNA breaks by targeting tubulin and topoisomerase II, respectively. However, few studies are dedicated to exploring the interactions between PTOX derivatives and downstream cancer-related signaling pathways, which is reasonably important for gaining insight into the role of PTOX. This review provides a comprehensive analysis of the role of PTOX derivatives in the biological behavior of tumors and potential molecular signaling pathways, aiming to help researchers design and develop better PTOX derivatives.

Abstract
Cancer continues to be one of the leading contributors towards global disease burden. According to NIH, cancer incidence rate per year will increase to 23.6 million by 2030. Even though cancer continues to be a major proportion of the disease burden worldwide, it has the lowest clinical trial success rate amongst other diseases. Hence, there is an unmet need for novel, affordable and effective anti-neoplastic medications. As a result, a growing interest has sparkled amongst researchers towards drug repurposing. Drug repurposing follows the principle of polypharmacology, which states, "any drug with multiple targets or off targets can present several modes of action". Drug repurposing also known as drug rechanneling, or drug repositioning is an economic and reliable approach that identifies new disease treatment of already approved drugs. Repurposing guarantees expedited access of drugs to the patients as these drugs are already FDA approved and their safety and toxicity profile is completely established. Epidemiological studies have identified the decreased occurrence of oncological or non-oncological conditions in patients undergoing treatment with FDA approved drugs. Data from multiple experimental studies and clinical observations have depicted that several non-neoplastic drugs have potential anticancer activity. In this review, we have summarized the potential anti-cancer effects of anti-psychotic, anti-malarial, anti-viral and anti-emetic drugs with a brief overview on their mechanism and pathways in different cancer types. This review highlights promising evidences for the repurposing of drugs in oncology.

Abstract
Gemcitabine (Gem) is a standard first-line treatment for pancreatic cancer (PC). However, its chemotherapeutic efficacy is hampered by various limitations such as short half-life, metabolic inactivation, and lack of tumor localizing. We previously synthesized a lipophilic Gem derivative (Gem formyl hexadecyl ester, GemC16) that exhibited improved antitumor activity in vitro. In this study, a target ligand N,N-dimethyl-1,3-propanediamine was conjugated to 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[hydroxyl succinimidyl (polyethylene glycol-2000)] (DSPE-PEG-NHS) to form DSPE-PEG-2N. Then, pancreas-targeting liposomes (2N-LPs) were prepared using the film dispersion-ultrasonic method. GemC16-loaded 2N-LPs displayed near-spherical shapes with an average size distribution of 157.2 nm (polydispersity index (PDI) = 0.201). The encapsulation efficiency of GemC16 was up to 97.3% with a loading capacity of 8.9%. In human PC cell line (BxPC-3) and rat pancreatic acinar cell line (AR42J), cellular uptake of 2N-LPs was significantly enhanced compared with that of unmodified PEG-LPs. 2N-LPs exhibited more potent in vitro cytotoxicity against BxPC-3 and AR42J cell lines than PEG-LPs. After systemic administration in mice, 2N-LPs remarkably increased drug distribution in the pancreas. In an orthotopic tumor mouse model of PC, GemC16-bearing liposomes were more effective in preventing tumor growth than free GemC16. Among these treatments, 2N-LPs showed the best curative effect. Together, 2N-LPs represent a promising nanocarrier to achieve pancreas-targeting drug delivery, and this work would provide new ideas for the chemotherapy of PC.

Abstract
Cancer metastasis is the main cause for the high mortality in breast cancer patients. In this work we developed a polymer POEG-st-Pmor for targeted co-delivery of IL-36γ expression plasmid and doxorubicin (Dox) to lung metastasis of breast cancer. The polymer readily formed micelles that were effective in loading Dox and simultaneously forming complexes with IL-36γ plasmid. Interestingly, particles co-loaded with Dox and plasmid was significantly smaller and more stable than the particles loaded with Dox only. Gene transfection in both lungs and s.c. tumors was significantly higher with our polymer compared to PEI. In addition, the Dox + IL-36γ/POEG-st-Pmor not only could bring improved anti-metastatic effect but synergistically enhance the type I immune response by increasing the IFN-γ positive CD4+ and CD8+ T cells and simultaneously decreasing the immunosuppressive myeloid-derived suppressor cells in the lung. POEG-st-Pmor may represent a simple and effective delivery system for an optimal chemo-gene combination therapy.

Abstract
Asthma is one of the most prevalent chronic inflammatory diseases of lung. Current asthma therapy using inhaled corticosteroid often results in undesired treatment outcome due to poor compliance and drugs’ lack of tissue specificity. N,N,N’-trimethyl-N’-(2-hydroxyl-3-methyl-5-123Iiodobenzyl)-1,3-propanediamine (HIPD), a phenolic propanediamine derivative, has been used as an imaging agent for localized pulmonary diseases. Inspired by this, N,N,N’-trimethyl-N’-(4-hydroxyl-benzyl)-1,3-propanediamine (TPD), a new HIPD analog, was proposed as a lung-targeting ligand and covalently conjugated to an anti-inflammatory compound Rhein for asthma therapy. Cellular uptake efficiency of TPD-Rhein by A549 cells was significantly enhanced compared with Rhein. The enhanced cellular uptake was mainly mediated by organic cation transporters (OCTs) in an active manner, showing concentration- and energy-dependent. After systemic administration in rats, TPD-Rhein specifically distributed to lungs, displaying the highest Cmax and AUC0−t values of all tested tissues and resulting in a 13-fold increase in Cmax and a 103-fold increase in AUC0−t for lung compared with Rhein. Also, TPD-Rhein remarkably decreased serum histamine levels, serum IL-5 levels as well as bronchoalveolar lavage fluid IL-5 levels in lungs of asthmatic rats challenged by ovalbumin (OVA). Accordingly, histological examinations demonstrated that TPD-Rhein attenuated lung inflammation in rats, with no apparent toxicity against major organs. Together, phenolic propanediamine-based lung-targeting approach represents an efficient and safe strategy for asthma therapy.

Abstract
Accumulating evidence suggests that the dysregulation of long non-coding RNAs (lncRNAs) serves vital roles in the incidence and progression of lung cancer. However, the molecular mechanisms of LINC00968, a recently identified lncRNA, remain unknown. The objective of present study was to investigate the role of a prospective lncRNA-miRNA‑mRNA network regulated by LINC00968 in non-small cell lung cancer cells. Following the transfection of lentiviruses carrying LINC00968 into A549 cells, the microRNA (miRNA) expression profile of the cells in response to the overexpression of LINC00968 was detected using an miRNA microarray. Five differentially expressed miRNAs (DEMs) with LINC00968 overexpression were obtained, including miR-9-3p, miR‑22-5p, miR-668-3p, miR‑3675-3p and miR-4536-3p. Five target prediction algorithms and three target validation algorithms were used to obtain 1,888 prospective target genes of the five DEMs. The result of Gene Ontology analysis suggested that these five DEMs were involved in complex cellular pathways, which included intracellular transport, organelle lumen and nucleotide binding. Furthermore, analysis of Kyoto Encyclopedia of Genes and Genomes pathways indicated that the five DEMs were important regulators in the adherens junction and focal adhesion. An lncRNA-miRNA-mRNA regulatory network and a protein-protein interaction network were then constructed. Eventually, a prospective lncRNA‑miRNA-mRNA regulatory network of LINC00968, three miRNAs (miR-9, miR-22 and miR-4536) and two genes (polo-like kinase 1 and exportin-1) was obtained following validation in the Cancer Genome Atlas database. These results may provide novel insights to support future research into lncRNA in lung cancer.

Abstract
Acute pancreatitis (AP) is a sudden inflammation of the pancreas with high mortality rate worldwide. As a severe complication to AP, acute lung injury has been the major cause of death among patients with AP. Poor penetration across the blood pancreas barrier (BPB) and insufficient drug accumulation at the target site often result in poor therapeutic outcome. Our previous work successfully demonstrated a dual-specific targeting strategy to pancreas and lung using a phenolic propanediamine moiety. Inspired by this, a simplified ligand structure, N,N-dimethyl tertiary amino group, was covalently conjugated to celastrol (CLT) to afford tertiary amino conjugates via either an ester (CP) or an amide linkage (CTA). With sufficient plasma stability, CTA was subjected to the following studies. Compared to CLT, CTA exhibited excellent cellular uptake efficiency in both rat pancreatic acinar cell line (AR42J) and human pulmonary alveolar epithelial cell line (A549). Organic cation transporters were proven to be responsible for this active transport process. Given systemically, CTA specifically distributed to pancreases and lungs in rats thus resulting in a 2.59-fold and 3.31-fold increase in tissue-specific accumulation as compared to CLT. After CTA treatment, tissue lesions were greatly alleviated and the levels of proinflammatory cytokines were downregulated in rats with sodium taurocholate induced AP. Furthermore, CTA demonstrated marginal adverse effect against major organs with reduced cardiac toxicity compared to CLT. Together, tertiary amine mediated dual pancreas- and lung-targeting therapy represents an efficient and safe strategy for AP management.
