Abstract
Metastatic breast cancer (mBC) continues to be a leading cause of cancer-related death in women. Even though mortality rates have improved over recent years, the 5-year survival rate of advanced BC is still at only 27%. As researchers and clinicians attempt to tackle this challenge, there has been extensive research and many trials studying treatment options for BC patients with metastatic disease, with numerous new therapies being discovered as a result. We review the most pertinent novel agents to enter the scope of BC treatment, including CDK4/6 inhibitors, PI3K inhibitors, mTOR inhibitors, immunotherapy, PARP inhibitors, and more.

Abstract
Lung cancer is one of the leading causes of cancer-related mortality worldwide. Non-small cell lung cancer (NSCLC) is the most common pathological type of lung cancer. Long non-coding RNAs (lncRNAs) are promising novel diagnostic and prognostic biomarkers, as well as potential therapeutic targets for lung cancer. Long non-coding RNAs (lncRNAs) have been demonstrated to modulate tumor cells proliferation, cell cycle progression, invasion, and metastasis by regulating gene expression at transcriptional, post-transcriptional, and epigenetic levels. The oncogenic aberrant Wnt/β-catenin signaling is prominent in lung cancer, playing a vital role in tumorigenesis, prognosis, and resistance to therapy. Interestingly, compelling studies have demonstrated that lncRNAs exert either oncogenic or tumor suppressor roles by regulating Wnt/β-catenin signaling. In this review, we aim to present the current accumulated knowledge regarding the roles of Wnt/β-catenin signaling-regulated lncRNAs in the pathogenesis of non-small cell lung cancer (NSCLC). Better understanding of the effects of lncRNAs on Wnt/β-catenin signaling might contribute to the improved understanding of the molecular tumor pathogenesis and to the uncovering of novel therapeutic targets in NSCLC.

Abstract
Treatment decisions for breast cancer are based on staging and hormone receptor expression and include chemotherapies and endocrine therapy. While effective in many cases, some breast cancers are resistant to therapy, metastasize and recur, leading to eventual death. Higher percentages of tumor-initiating cancer stem cells (CSCs) may contribute to the increased aggressiveness, chemoresistance, and worse outcomes among breast cancer. This may be particularly true in triple-negative breast cancers (TNBCs) which have higher percentages of CSCs and are associated with worse outcomes. In recent years, increasing numbers of long non-coding RNAs (lncRNAs) have been identified as playing an important role in breast cancer progression and some of these have been specifically associated within the CSC populations of breast cancers. LncRNAs are non-protein-coding transcripts greater than 200 nucleotides which can have critical functions in gene expression regulation. The preclinical evidence regarding lncRNA antagonists for the treatment of cancer is promising and therefore, presents a potential novel approach for treating breast cancer and targeting therapy-resistant CSCs within these tumors. Herein, we summarize the lncRNAs that have been identified as functionally relevant in breast CSCs. Furthermore, our review of the literature and analysis of patient datasets has revealed that many of these breast CSC-associated lncRNAs are also enriched in TNBC. Together, this suggests that these lncRNAs may be playing a particularly important role in TNBC. Thus, certain breast cancer-promoting/CSC-associated lncRNAs could be targeted in the treatment of TNBCs and the CSCs within these tumors should be susceptible to anti-lncRNA therapy.

Abstract
Short interfering RNA (siRNA) has been investigated as a promising modality of cancer treatment due to its capability to target specific target genes for downregulation. However, the successful application of this strategy depends on producing a safe and effective carrier system for delivering siRNA to the tumor. Thus, investigation of siRNA delivery carriers is a fundamental step in the field of siRNA-based therapeutics. In the current research, the surface of selenium nanoparticles (SeNPs) were modified with the tumor-targeted molecular RGDfC peptide with positive charge to synthetize the biocompatible siRNA carrier RGDfC-SeNPs. Subsequently, KLK12-siRNA was loaded onto the surface of RGDfC-SeNPs to create functionalized nanoparticles (RGDfC-Se@siRNA) that we tested for in vitro and in vivo antitumor efficacy. We measured significantly greater particle uptake in HT-29 colorectal cancer cells relative to HUVECs, providing evidence for the targeted delivery of RGDfC-Se@siRNA. We found that RGDfC-Se@siRNA could enter HT-29 cells primarily via clathrin-mediated endocytosis. Further, these particles experienced faster siRNA release in an acidic microenvironment compared to pH 7.4. The results from quantitative PCR and Western blot assays suggested that the target gene of KLK12 in HT-29 cells were obviously silenced by RGDfC-Se@siRNA. The further biological studies showed that treatment with RGDfC-Se@siRNA had ability to suppress the proliferation and migration/invasion of HT-29 cells, and triggered HT-29 cells apoptosis. RGDfC-Se@siRNA could induce the mitochondrial membrane potential (MMP) disruption and enhance the reactive oxygen species (ROS) generation in HT-29 cells, indicating that RGDfC-Se@siRNA induced the HT-29 cells apoptosis possibly by a ROS-mediated mitochondrial dysfunction pathway. Importantly, the in vivo antitumor study also verified that RGDfC-Se@siRNA could significantly suppress the growth of tumor in vivo. In addition, we did not observe any signs of systemic or tissue-specific toxicity after administration of RGDfC-Se@siRNA in mice. As a whole, these findings suggest that RGDfC-Se@siRNA has promising potential as a therapy for colorectal cancer.

Role of the Pumilio gene in the reproductive system of Schistosoma japonicum. Parasitol Res 2020; 119:501-511.

Abstract
The elimination of schistosomiasis, a parasitic disease caused by Schistosoma and a major source of morbidity and mortality in developing countries, faces serious challenges. Although the pumilio protein regulates the reproductive organ development in many species, its role in Schistosoma japonicum is unknown. Thus, this study investigated the function of pumilio in S. japonicum reproduction. The complete coding sequences of S. japonicum Pumilio1 (SjPum1) and SjPum2 genes were cloned and characterized. The full-length open-reading frame SjPum1 (2613 nucleotides) and SjPum2 (4479 nucleotides) genes were obtained. Bioinformatics analysis showed that those genes belonged to the PUF (pumilio and FBF) family. Quantitative polymerase chain reaction analyses revealed that SjPum1 and SjPum2 were differentially expressed throughout the S. japonicum life cycle and were highly expressed in reproductive organs. In situ hybridization results showed that mRNA expression of SjPum2 was higher than that of SjPum1 in the ovary and testis. Knocking down SjPum2 using RNA interference techniques to explore potential reproductive functions showed that compared with the control (untransfected or scrambled mRNA-transfected) worms, the morphology of both male and female reproductive organs was altered, the number of eggs produced by paired females was significantly decreased, and the transcription levels of caspase 3 and caspase 7 genes related to apoptosis were significantly increased. The transcription level of Nanos1 gene which related to reproduction was also significantly increased. Therefore, SjPum2 may play a role in the reproductive development of S. japonicum.

Abstract
Abstract: Epithelial-mesenchymal transition (EMT) has emerged as a key regulator of cell invasion and metastasis in cancers. Besides the acquisition of migratory/invasive abilities, the EMT process is tightly connected with the generation of cancer stem cells (CSCs), thus contributing to chemoresistance. However, although EMT represents a relevant therapeutic target for cancer treatment, its application in the clinic is still limited due to various reasons, including tumor-stage heterogeneity, molecular-cellular target specificity, and appropriate drug delivery. Concerning this last point, different nanomaterials may be used to counteract EMT induction, providing novel therapeutic tools against many different cancers. In this review, (1) we discuss the application of various nanomaterials for EMT-based therapies in cancer, (2) we summarize the therapeutic relevance of some of the proposed EMT targets, and (3) we review the potential benefits and weaknesses of each approach.

Abstract
MR molecular imaging (MRMI) of abundant oncogenic biomarkers in tumor microenvironment has the potential to provide precision cancer imaging in high resolution. Extradomain-B fibronectin (EDB-FN) is an oncogenic extracellular matrix protein, highly expressed in aggressive triple negative breast cancer. A targeted macrocyclic gadolinium-based contrast agent (GBCA) ZD2-N3-Gd(HP-DO3A) (MT218), specific to EDB-FN, was developed for MRMI of aggressive breast cancer. The effectiveness of different doses of MT218 for MRMI was tested in MDA-MB-231 and Hs578T human triple negative breast cancer models. At clinical dose of 0.1 and subclinical dose of 0.04 mmol Gd/kg, MT218 rapidly bound to the extracellular matrix EDB-FN and produced robust tumor contrast enhancement in both the tumor models, as early as 1-30 min post-injection. Substantial tumor enhancement was also observed in both the models with MT218 at doses as low as 0.02 mmol Gd/kg, which was significantly better than the clinical agent Gd(HP-DO3A) at 0.1 mmol Gd/kg. Little non-specific enhancement was observed in the normal tissues including liver, spleen, and brain for MT218 at all the tested doses, with renal clearance at 30 min. These results demonstrate that MRMI with reduced doses of MT218 is safe and effective for sensitive and specific imaging of aggressive breast cancers.

Abstract
Small interfering RNA (siRNA) has an established and precise mode of action to achieve protein knockdown. With the ability to target any protein, it is very attractive as a potential therapeutic for a plethora of diseases driven by the (over)expression of certain proteins. Utilizing siRNA to understand and treat cancer, a disease largely driven by genetic aberration, is thus actively investigated. However, the main hurdle for the clinical translation of siRNA therapeutics is to achieve effective delivery of siRNA molecules to tumors and the site of action, the cytosol, within cancer cells. Several nanoparticle delivery platforms for siRNA have been developed. In this Review, we describe recent efforts in developing siRNA therapeutics for the treatment of cancer, with particular emphasis on breast cancer. Instead of conventionally targeting proliferation and apoptosis aspects of tumorigenesis, we focus on recent attempts in targeting cancer's metastasis, drug resistance, and immune evasion, which are considered more challenging and less manageable in clinics with current therapeutic molecules. siRNA can target all proteins, including traditionally undruggable proteins, and is thus poised to address these clinical challenges. Evidence also suggests that siRNA can be superior to antibodies or small molecule inhibitors when inhibiting the same druggable pathway. In addition to cancer cells, the role of the tumor microenvironment has been increasingly appreciated. Components in the tumor microenvironment, particularly immune cells, and thus siRNA-based immunotherapy, are under extensive investigation. Lastly, multiple siRNAs with or without additional drugs can be codelivered on the same nanoparticle to the same target site of action, maximizing their potential synergy while limiting off-target toxicity.

Particularly, the morbidity of triple-negative breast cancer (TNBC) is higher than that of other BC types due to its high molecular heterogeneity, metastatic potential and poor prognosis. TNBC lacks of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2), so there are still no effective treatment methods for TNBC. Here, we reviewed the classification of TNBC, its molecular mechanisms of pathogenesis, treatment methods and prognosis. Finding effective targets is critical for the treatment of TNBC. Also, refining the classification of TNBC is benefited to choose the treatment of TNBC, because the sensitivity of chemotherapy is different in different TNBC. Some new treatment methods have been proposed in recent years, such as nutritional therapy and noncoding RNA treatment methods. There are some disadvantages, such as the side effect on normal cells after nutrient deprivation, low specificity and instability of noncoding RNA. More studies are necessary to improve the treatment of TNBC.

Abstract
As a highly heterogeneous malignancy, breast cancer (BC) has become the most significant threat to female health. Distant metastasis and therapy resistance of BC are responsible for most of the cases of mortality and recurrence. Distant metastasis relies on an array of processes, such as cell proliferation, epithelial-to-mesenchymal transition (EMT), mesenchymal-to-epithelial transition (MET), and angiogenesis. Long non-coding RNA (lncRNA) refers to a class of non-coding RNA with a length of over 200 nucleotides. Currently, a rising number of studies have managed to investigate the association between BC and lncRNA. In this study, we summarized how lncRNA has dual effects in BC metastasis by regulating invasion, migration, and distant metastasis of BC cells. We also emphasize that lncRNA has crucial regulatory effects in the stemness and angiogenesis of BC. Clinically, some lncRNAs can regulate chemotherapy sensitivity in BC patients and may function as novel biomarkers to diagnose or predict prognosis for BC patients. The exact impact on clinical relevance deserves further study. This review can be an approach to understanding the dual effects of lncRNAs in BC, thereby linking lncRNAs to quasi-personalized treatment in the future.

Abstract
Long noncoding RNAs (lncRNAs) are emerging as important regulators of numerous biological processes, especially in cancer development. Aberrantly expressed and specifically located in tumor cells, they exert distinct functions in different cancers via regulating multiple downstream targets such as chromatins, RNAs, and proteins. Differentiation antagonizing non-protein coding RNA (DANCR) is a cytoplasmic lncRNA that generally works as a tumor promoter. Mechanically, DANCR promotes the functions of vital components in the oncogene network by sponging their corresponding microRNAs or by interacting with various regulating proteins. DANCR's distinct expression in tumor cells and collective involvement in pro-tumor pathways make it a promising therapeutic target for broad cancer treatment. Herein, we summarize the functions and molecular mechanism of DANCR in human cancers. Furthermore, we introduce the use of CRISPR/Cas9, antisense oligonucleotides and small interfering RNAs as well as viral, lipid, or exosomal vectors for onco-lncRNA targeted treatment. Conclusively, DANCR is a considerable promoter of cancers with a bright prospect in targeted therapy.

Abstract
Nanomedicine is a promising strategy for improving clinical outcomes for cancer therapies, by improving drug efficacy through enhanced delivery to disease sites. It is of importance for ultimate clinical success to consider the contributing factors to achieving this goal, such as size, chemistry, and functionality of nanoparticle delivery systems, and how these parameters influence tumor localization and uptake. This Topical Review will first discuss the evolution and progress of nanoparticles for cancer drug delivery and the current challenges that remain to be addressed. Strategies for overcoming the limitations of passive targeting through active targeting approaches, and the current state of such nanomedicines in the clinic will be highlighted. Finally, novel approaches toward the design of active targeted nanoparticles building on our growing understanding of nanobio interactions are considered, in order to shed light on future design considerations for accelerating clinical translation of nanomedicines.

Abstract
Nanoparticle based siRNA formulations often suffer from aggregation and loss of function during storage. We in this study report a frozen targeted RGD-polyethylene glycol (PEG)-ECO/siβ3 nanoparticle formulation with a prolonged shelf life and preserved nanoparticle functionality. The targeted RGD-PEG-ECO/siβ3 nanoparticles are formed by step-wised self-assembly of RGD-PEG-maleimide, ECO, and siRNA. The nanoparticles have a diameter of 224.5 ± 9.41 nm and a zeta potential to 45.96 ± 3.67 mV in water and a size of 234.34 ± 3.01 nm and a near neutral zeta potential in saline solution. The addition of sucrose does not affect their size and zeta potential and substantially preserves the integrity and biological activities of frozen and lyophilized formulations of the targeted nanoparticles. The frozen formulation with as low as 5% sucrose retains nanoparticle integrity (90% siRNA encapsulation), size distribution (polydispersity index [PDI] ≤20%), and functionality (at least 75% silencing efficiency) at -80°C for at least 1 year. The frozen RGD-PEG-ECO/siβ3 nanoparticle formulation exhibits excellent biocompatibility, with no adverse effects on hemocompatibility and minimal immunogenicity. As RNAi holds the promise in treating the previously untreatable diseases, the frozen nanoparticle formulation with the low sucrose concentration has the potential to be a delivery platform for clinical translation of RNAi therapeutics.

Abstract
Gene therapy with RNA and pDNA-based drugs is limited by poor enzymatic stability and poor cellular permeation. The delivery of nucleic acids, in particular by the oral route, remains a major hurdle. This review will focus on the barriers to the oral delivery of nucleic acids and the strategies, in particular formulation strategies, which have been developed to overcome these barriers. Due to their very low oral bioavailability, the most obvious and most investigated biomedical applications for their oral delivery are related to the local treatment of inflammatory bowel diseases and colorectal cancers. Preclinical data but not yet clinical studies support the potential use of the oral route for the local delivery of formulated nucleic acid-based drugs.
