Abstract
RNA interference (RNAi) provides researchers with a versatile means to modulate target gene expression. The major forms of RNAi molecules, genome-derived microRNAs (miRNAs) and exogenous small interfering RNAs (siRNAs), converge into RNA-induced silencing complexes to achieve posttranscriptional gene regulation. RNAi has proven to be an adaptable and powerful therapeutic strategy where advancements in chemistry and pharmaceutics continue to bring RNAi-based drugs into the clinic. With four siRNA medications already approved by the US Food and Drug Administration (FDA), several RNAi-based therapeutics continue to advance to clinical trials with functions that closely resemble their endogenous counterparts. Although intended to enhance stability and improve efficacy, chemical modifications may increase risk of off-target effects by altering RNA structure, folding, and biologic activity away from their natural equivalents. Novel technologies in development today seek to use intact cells to yield true biologic RNAi agents that better represent the structures, stabilities, activities, and safety profiles of natural RNA molecules. In this review, we provide an examination of the mechanisms of action of endogenous miRNAs and exogenous siRNAs, the physiologic and pharmacokinetic barriers to therapeutic RNA delivery, and a summary of the chemical modifications and delivery platforms in use. We overview the pharmacology of the four FDA-approved siRNA medications (patisiran, givosiran, lumasiran, and inclisiran) as well as five siRNAs and several miRNA-based therapeutics currently in clinical trials. Furthermore, we discuss the direct expression and stable carrier-based, in vivo production of novel biologic RNAi agents for research and development. SIGNIFICANCE STATEMENT: In our review, we summarize the major concepts of RNA interference (RNAi), molecular mechanisms, and current state and challenges of RNAi drug development. We focus our discussion on the pharmacology of US Food and Drug Administration-approved RNAi medications and those siRNAs and miRNA-based therapeutics that entered the clinical investigations. Novel approaches to producing new true biological RNAi molecules for research and development are highlighted.

Abstract
Since they were first synthesized in 1965 by Treibs and Jacob, squaraine dyes have revolutionized the polymethine dyes' 'universe' and their potential applications due to their indisputable physical, chemical and biological properties. After 30 years and up to the present, various research teams have dedicated themselves to studying the squaraines' photodynamic therapy application using in vitro and in vivo models. The various structural modifications made to these compounds, as well as the influence they have shown to have in their phototherapeutic activity, are the main focus of the present review. Finally, the most evident limitations of this class of dyes, as well as future perspectives in the sense of hypothetically successfully overcoming them, are suggested by the authors.

Microfluidic system with light intensity filters facilitating the application of photodynamic therapy for high-throughput drug screening. Photodiagnosis Photodyn Ther 2022; 38:102812. [PMID: 35304312 DOI: 10.1016/j.pdpdt.2022.102812] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Revised: 02/26/2022] [Accepted: 03/14/2022] [Indexed: 11/24/2022]
Abstract
BACKGROUND Photodynamic therapy utilizes light energy with a photosensitizer (a light-sensitive drug) to kill cancer cells through light activation. When a photosensitizer is injected into the bloodstream and exposed to a specific wavelength of light, it generates oxygen to destroy or damage nearby cancer cells, while minimizing side effects on normal cells. Although photodynamic therapy is effective for treating cancer, various parameters, such as the optimum light intensity and photosensitizer dose, are currently poorly understood due to the complexity of conventional experimental schemes. METHODS To effectively perform a simultaneous single parallel test for several different light irradiation conditions on each cell, a microfluidic device was developed to generate eight different intensities from a single light-emitting diode source, through eight different color dye concentrations functioning as light intensity filters. To show that this novel high-throughput microfluidic system can analyze the effects of various light intensities during photodynamic therapy, the optimum light intensities and photosensitizer doses were determined for two different cancer cell lines. RESULTS Optimum light intensities and photosensitizer were determined for all cell lines. The photodynamic therapy effects in response to different irradiated light intensities were characterized by analyzing cell viability after photosensitizer treatment CONCLUSIONS: : The developed platform is capable of being used as a photodynamic therapy screening tool. The proposed platform provides a simple and robust way to optimize the combined parameters of light intensity and dosage for diverse types of cancer cells.

Abstract
Photodynamic therapy (PDT) is a promising anticancer noninvasive method and has great potential for clinical applications. Unfortunately, PDT still has many limitations, such as metastatic tumor at unknown sites, inadequate light delivery and a lack of sufficient oxygen. Recent studies have demonstrated that photodynamic therapy in combination with other therapies can enhance anticancer effects. The development of new nanomaterials provides a platform for the codelivery of two or more therapeutic drugs, which is a promising cancer treatment method. The use of multifunctional nanocarriers for the codelivery of two or more drugs can improve physical and chemical properties, increase tumor site aggregation, and enhance the antitumor effect through synergistic actions, which is worthy of further study. This review focuses on the latest research progress on the synergistic enhancement of PDT by simultaneous multidrug administration using codelivery nanocarriers. We introduce the design of codelivery nanocarriers and discuss the mechanism of PDT combined with other antitumor methods. The combination of PDT and chemotherapy, gene therapy, immunotherapy, photothermal therapy, hyperthermia, radiotherapy, sonodynamic therapy and even multidrug therapy are discussed to provide a comprehensive understanding.

Abstract
BACKGROUND Nuclear factor-κB (NF-κB) has been identified as the major link between inflammation and cancer. Natural agents that inhibit this pathway are essential in attenuating inflammation induced by cancer or chemotherapeutic drugs. High intake of Brassicaceae vegetables has been determined to modulate essential pathways related to chronic diseases. In this study, we investigated the anti-proliferative and anti-inflammatory effects of the indole glucosinolates; indole-3-carbinol (I3C) and its metabolite 3,3-diindolylmethane (DIM) on the inflammatory biomarkers and miRNAs controlling the NF-κB pathway. METHODS AND RESULTS In our study, we inoculated Ehrlich ascites carcinoma (EAC) cells in female albino mice, which increased their packed cell volume and induced a significant increase in the levels of several cytokines and inflammatory biomarkers (NF-κB IL-6, IL-1b, TNF-α, and NO). A significant elevation in inflammatory-medicated miRNAs (miR-31 and miR-21) was also noted. Treatment with 5-fluorouracil (5-FU) significantly reduced packed cell volume and viable cell count. However, it was accompanied by a significant increase in the levels of inflammatory markers and expression of miR-31 and miR-21. Nevertheless, although treatment with indoles (I3C and DIM) significantly reduced the packed cell volume and viable cell count, their prominent effect was the marked reduction of all inflammatory biomarkers compared to both the EAC untreated group and the EAC group treated with 5-FU. Moreover, the anti-inflammatory effect of I3C or DIM was accompanied by a significant decrease in the expression of miR-31 and miR-21. CONCLUSION Our findings have; therefore, revealed that I3C and DIM have strong anti-inflammatory effects, implying that their use as a co-treatment with chemotherapeutic drugs can effectively improve the anti-tumor effect of chemotherapeutic drugs.

In silico analysis of the association of hsa-miR-16 expression and cell survival in MDA-MB-231 breast cancer cells subjected to photodynamic therapy. Photodiagnosis Photodyn Ther 2020; 33:102106. [PMID: 33217568 DOI: 10.1016/j.pdpdt.2020.102106] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 10/28/2020] [Accepted: 11/09/2020] [Indexed: 01/10/2023]
Abstract
BACKGROUND Breast cancer is the most common malignancy effecting women, and the triple-negative breast cancer (TNBC) subtype is particularly aggressive. This study aimed to evaluate the differential expression pattern of microRNAs (miRNAs) between untreated MDA-MB-231 cells (TNBC cell model) and those that survived photodynamic therapy (PDT) to gain insights into cell survival mechanisms. METHODS Two PDT cycles were applied to MDA-MB-231 cells, using δ-aminolevulinic acid (ALA) followed by laser light at 635 nm. RNA was obtained from cells surviving PDT and untreated cells. The miRNAs expression profile was analyzed to detect the differences between the two groups. The potential target network of hsa-miR-16 was examined in silico with the integrative database Ingenuity® Pathway Analysis software. RESULTS After the first and second PDT cycles, 17.8% and 49.6% of the MDA-MB-231 cells were viable. Microarray profiling of miRNAs showed decreased hsa-miR-16 expression (p < 0.05) in MDA-MB-231 cells surviving PDT when compared to the control cells. The predicted downstream targets of hsa-miR-16 were: 1) tumor suppressor protein 53; 2) molecules related to the cell cycle, such as cyclin D1, D3, and E1, and checkpoint kinase 1; 3) cell proliferation molecules, including fibroblast growth factor 1, 2 and 7 and fibroblast growth factor receptor 1; and 4) apoptosis-related molecules, consisting of BCL-2, B-cell leukemia/lymphoma 2, caspase 3, and cytochrome c. CONCLUSIONS The differential expression of hsa-miR-16 between untreated MDA-MB-231 cells and those surviving PDT has not been previously reported. There was a lower expression of hsa-miR-16 in treated cells, which probably altered its downstream target network. In silico analysis predicted, a network related to the cell cycle, proliferation and apoptosis. These results are congruent with previous descriptions of hsa-miR-16 as a tumor suppressor and suggest that the treated population has increased their capacity to survive.

Modulatory Effect of Indoles on the Expression of miRNAs Regulating G1/S Cell Cycle Phase in Breast Cancer Cells. Appl Biochem Biotechnol 2020; 192:1208-1223.

Abstract
Indole-3-carbinol (I3C) is a naturally occurring glucosinolate found in Brassica vegetables that is usually converted in gastric acidic environment to the efficient metabolite 3,3'-diindolylmethane (DIM). Both indoles (I3C and DIM) are known chemopreventive agents for various cancers including breast cancer. This study aimed to investigate the influence of both indoles on the tumor suppressor miRNAs (let-7a-e, miR-15a, miR-16, miR-17-5p, miR-19a, and miR-20a) and oncomiRs (miR-181a, miR-181b, miR-210, miR-221, and miR-106a), which are controlling the cell cycle key regulators: cyclin-dependent kinases (CDKs), CDK inhibitor p27Kip1, and cyclin D1. Our results indicated that both indoles generally elevated the expression of the tumor suppressor miRNAs let-7a-e, miR-19a, miR-17-5p, and miR-20a and decreased the expression of the oncomiR list. Both indoles were able to significantly suppress the expression of CDK4 and CDK6 as well as the apoptotic markers Bcl-2 and survivin. Both indoles decreased cyclin-D1 protein, where I3C decreased cytoplasmic and nuclear cyclin-D1 significantly. Cytoplasmic and nuclear P27Kip1 showed overexpression following treatment with I3C higher than that detected following DIM treatment. This study provides a mechanistic elucidation of the previously reported cell cycle arrest by I3C and DIM in breast cancer cells suggesting that this effect could be through modulation of miRNAs expression that, in turn, regulates the genetic network controlling the G1/S phase in cell cycle progression.

Abstract
BACKGROUND Colorectal cancer (CRC) is the third most common malignant tumor worldwide. Photodynamic therapy (PDT) is an emerging modality for the treatment of solid tumors. Sinoporphyrin sodium (DVDMS) is a new photosensitizer with good therapeutic killing effects on cancer cells. Recent findings have shown that microRNAs play important roles in many biological processes. However, the functions of microRNAs in DVDMS-induced PDT remain largely unclear. MATERIALS AND METHODS Proteins involved in endoplasmic reticulum (ER) stress and apoptosis of CX-1 cells treated with DVDMS-PDT were examined by Western blotting and cell viability assays. 15 candidate miRNAs targeting RNA-dependent protein kinase-like ER kinase (PERK) were screened and verified using the TargetScan, miRWalk and miRDB databases. The downstream pathways of candidate miRNAs with high scores were studied by cell transfection, qRT-PCR, Western blotting and dual-luciferase reporter assays. The subcellular location of DVDMS was confirmed by laser confocal microscopy. RESULTS DVDMS-PDT induced apoptosis via elevated ER stress and activation of the PERK/ATF4/CHOP/caspase cascade pathway in CX-1 cells. The endoplasmic reticulum was involved in the subcellular accumulation of DVDMS in CX-1 cells. Dual-luciferase reporting experiment confirmed that a direct crosslinking between miR-7112-3p and PERK. In addition, miR-7112-3p was highly expressed in CRC tissues compared with peripheral tissues. CONCLUSION Our work showed that miR-7112-3p directly targeted PERK and further regulated PERK/ATF4/CHOP/caspase cascade pathway, resulting in enhanced apoptosis in CX-1 cells treated with DVDMS-PDT.

Abstract
Highly efficient and stimulus-responsive nanomedicines for cancer treatment are currently receiving tremendous attention. In this study, an acid-triggered charge-reversible graphene-based all-in-one nanocomplex is appropriately designed by surface modification with multilayer polymers and simultaneous co-transportation of photosensitizer indocyanine green (ICG) and oligonucleotide inhibitor of miR-21 (miR-21i) to achieve highly efficient genetic phototherapy in a controlled manner. The nanocomplex (denoted as GPCP/miR-21i/ICG) effectively protects miR-21i from degradation and exhibits excellent photothermal/photochemical reactive oxygen species (ROS) generation as well as fluorescence imaging ability. The cargoes ICG and miR-21i can significantly be released at acidic pH compared with normal physiological medium and escaped from endosomes/lysosomes due to the acid-triggered charge reversal effect. Typically, the released miR-21i downregulate the endogenous miR-21 and result in the upregulation of the target proteins PTEN and Bax, thus increasing the phototherapeutic efficiency of ICG. High in vivo anticancer efficiency against the MDA-MB-231 triple-negative breast cancer (TNBC) model is obtained due to the combination of genetic regulation of miR-21i and the photokilling effect of ICG. This work highlights the great potential of this smart nanocomplex as an attractive modality of gene-photo combined treatment of cancer, especially for intractable TNBC.

Abstract
Current traditional drugs such as enzyme inhibitors and receptor agonists/antagonists present inherent limitations due to occupancy-driven pharmacology as the mode of action. Proteolysis targeting chimeras (PROTACs) are composed of an E3 ligand, a connecting linker and a target protein ligand, and are an attractive approach to specifically knockdown-targeted proteins utilizing an event-driven mode of action. The length, hydrophilicity and rigidity of connecting linkers play important role in creating a successful PROTAC. Some PROTACs with a triazole linker have displayed promising anticancer activity. This review provides an overview of PROTACs with a triazole scaffold and discusses its structure-activity relationship. Important milestones in the development of PROTACs are addressed and a critical analysis of this drug discovery strategy is also presented.

Abstract
Photodynamic Therapy (PDT) is a promising alternative treatment for malignancies based on photochemical reaction induced by Photosensitizers (PS) under light irradiation. Recent studies show that PDT caused the abundant release of exosomes from tumor tissues. It is well-known that exosomes as carriers play an important role in cell-cell communication through transporting many kinds of bioactive molecules (e.g. lipids, proteins, mRNA, miRNA and lncRNA). Therefore, to explore the role of exosomes in photodynamic anticancer therapy has been attracting significant attention. In the present paper, we will briefly introduce the basic principle of PDT and exosomes, and focus on discussing the role of exosomes in photodynamic anticancer therapy, to further enrich and boost the development of PDT.

Bioinformatics analysis of the interactions among lncRNA, miRNA and mRNA expression, genetic mutations and epigenetic modifications in hepatocellular carcinoma. Mol Med Rep 2018; 19:1356-1364. [PMID: 30535497 DOI: 10.3892/mmr.2018.9728] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2018] [Accepted: 11/21/2018] [Indexed: 11/05/2022] Open
Abstract
The present study aimed to investigate the regulatory networks involving long noncoding RNA (lncRNA), microRNA (miRNA), mRNA, genetic mutations and epigenetic modifications in hepatocellular carcinoma (HCC) by analyzing datasets from The Cancer Genome Atlas (TCGA) database. TCGA was mined, and miRNAs, lncRNAs and mRNAs that were differentially expressed in HCC were identified using R software. A gene regulatory network was constructed using Cytoscape software. Representative genes were selected for functional enrichment analysis using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes. The associations among various proteins and protein networks were identified using the online software Search Tool for the Retrieval of Interacting Genes/Proteins. The cBioPortal database was used to analyze the association between genetic mutations and epigenetic modification, and the development of HCC. A total of 35 mRNAs were predicted to be targeted by 77 lncRNAs and 16 miRNAs, establishing a lncRNA‑miRNA‑mRNA regulatory network for HCC. Multivariable Cox regression analysis suggested that long intergenic non‑protein coding RNA 200, miRNA‑137, PDZ binding kinase and DNA polymerase θ were independent prognostic factors. In a regulatory network centered on miRNA‑424, six mRNA target genes were associated with HCC survival rates. Protein‑protein interaction analysis suggested that cell division cycle 25A (CDC25A) interacted with centrosomal protein 55 (CEP55), claspin, E2F transcription factor 7 and cyclin E1 (CCNE1. Mutations in CEP55 affected overall survival and disease‑free survival in HCC, whereas, mutations in CDC25A affected overall survival, and mutations in E2F7 affected disease‑free survival. Decreased methylation levels of CEP55, CDC25A and CCNE1 were associated with vascular invasion. The survival rate of patients with hypermethylation of CCNE1 and CEP55 was significantly associated with the rate of methylation of these loci. The present study provides an integrated bioinformatics analysis of gene expression, genetic mutations and epigenetic modifications that may be associated with the development of HCC.

J Formos Med Assoc 2018; 117:738-742. [PMID: 29936107 DOI: 10.1016/j.jfma.2018.05.018] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2018] [Revised: 05/23/2018] [Accepted: 05/25/2018] [Indexed: 01/28/2023] Open
Abstract
5-Aminolevulinic acid-mediated photodynamic therapy (ALA-PDT) has been used in the treatment of various precancerous and malignant lesions. Our previous work has demonstrated that ALA-PDT possesses the potential to serve as an adjuvant therapy against head and neck cancer via eliminating the cancer stem cells (CSCs) property. This study aimed to further investigate the possible molecular mechanism underlying the effect of ALA-PDT. Our results revealed that ALA-PDT upregulated the expression of microRNA-145 (miR-145) in two oral cancer cell lines. Overexpression of miR-145 in oral CSCs further enhanced the treatment effect of ALA-PDT with lower self-renewal, invasion capacities and reduced CD44 expression, while inhibition of miR-145 exhibited the opposite phenomena. These findings suggest that the anti-CSCs effect of ALA-PDT is due to an elevation of miR-145.

Abstract
BACKGROUND The human cervical carcinoma oncogenic mechanisms still remain elusive. Thus, we proposed to understand the biological role of a newly discovered therapeutic miRNA. METHODS MiR-1297 related to human cervical carcinoma was selected for this study. TaqMan qRT- PCR assay was used to profile miRNA, phosphatase and tensin homolog (PTEN) expression in randomly chosen tumour with non-tumour tissues, and the apoptosis factors expression. Cell proliferation was monitored by CCK-8 assay and colony formation assay. Apoptosis was determined by flow cytometry. Protein level was determined by western blotting. 3'UTR was performed to validate the direct binding sites of miR-1297 on PTEN. SPSS was used for statistical analyses. RESULTS MiR-1297 is repressed and PTEN activated in human cervical cancer tissues. After miR-1297 overexpression, HeLa cells had an increase in cell proliferation and decrease in apoptosis. PTEN expression is negatively correlation with miR-1297. PTEN silencing display the similar pattern as miRNA-1297 overexpression to inhibit HeLa cell growth and apoptosis in vitro. CONCLUSIONS Our data indicate that miR-1297 contribute to the human cervical carcinoma through PTEN. miR-1297 could be a reasonable miRNA for future studies.

Abstract
Aberrant microRNA-449a (miR-449a-5p) expression has been demonstrated to be associated with the development of various cancer types. However, the effect of miR-449a-5p on esophageal squamous cell carcinoma (ESCC) cell proliferation remains unknown. The present study aimed to determine whether miR-449a-5p may regulate ESCC cell proliferation via negative regulation of cyclin D1. Reverse transcription quantitative-polymerase chain reaction was used to measure the expression of miR-449a-5p in ESCC tissues and cells. Western blot was performed to analyze the protein level of cyclin D1. The proliferation of ESCC cells was determined by MTT and clone formation assay. Paired ESCC and adjacent normal esophageal squamous tissues were collected from patients with ESCC. It was demonstrated that miR-449a-5p expression was reduced, whereas cyclin D1 expression was increased in ESCC tissues compared with adjacent normal tissues. Proliferation was investigated in vivo using the ESCC cell line Eca-190. miR-449a-5p inhibitor transfection facilitated the proliferation of Eca-109 cells. By contrast, transfection with miR-449a-5p mimics inhibited Eca-109 cell proliferation. Furthermore, it was confirmed that miR-449a-5p directly bound to the 3′-untranslated region of cyclin D1. Transfection with cyclin D1 small interfering RNA reversed the effects of the miR-449a-5p inhibitor on Eca-109 cell proliferation. In conclusion, miR-449a-5p may control ESCC proliferation through the negative regulation of cyclin D1 expression.
