Yu H, Kohno S, Voon DCC, Hussein NH, Zhang Y, Nakayama J, Takegami Y, Takahashi C. RECK/GPR124-driven WNT signaling in pancreatic and gastric cancer cells. Cancer Sci 2024. [PMID: 38923741 DOI: 10.1111/cas.16258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Revised: 06/05/2024] [Accepted: 06/16/2024] [Indexed: 06/28/2024] Open
Abstract
RECK has been described to modulate extracellular matrix components through negative regulation of MMP activities. Recently, RECK was demonstrated to bind to an orphan G protein-coupled receptor GPR124 to mediate WNT7 signaling in nontumor contexts. Here, we attempted to clarify the role of RECK in driving WNT signaling in cancer cells. RECK and GPR124 formed a complex in 293T cells, and when both were expressed, WNT signaling was significantly enhanced in a WNT7-dependent manner. This cooperation was abolished when RECK mutants unable to bind to GPR124 were transduced. RECK stimulated the growth of KRAS-mutated pancreatic ductal adenocarcinoma (PDAC) cells with increased sensitivity to WNT inhibitor in a GPR124-dependent manner. A gastric cancer cell line SH10TC endogenously expresses both RECK and GPR124 under regular culture conditions. In this cell line, inhibited cell growth and WNT signaling as well as increased apoptosis in the GPR124 depletion was dominantly found over those in the RECK deletion. These findings suggest that RECK promotes tumor cell growth by positively modulating WNT signaling through GPR124. This study proposes that the RECK/GPR124 complex might be a good therapeutic target in PDAC and gastric cancer.

Wu X, Yang C, Li Z, Lv P, An X, Peng X, Li Y, Jiang X, Mao X, Chen D, Jia L, Yuan W. Dihydroartemisinin inhibits HNSCC invasion and migration by controlling miR-195-5p expression. Heliyon 2024; 10:e32522. [PMID: 38961909 PMCID: PMC11219504 DOI: 10.1016/j.heliyon.2024.e32522] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 06/04/2024] [Accepted: 06/05/2024] [Indexed: 07/05/2024] Open
Abstract
Objectives Dihydroartemisinin (DHA), an artemisinin derivative extracted from the traditional Chinese medicinal herb Artemisia annua, has the potential to suppress head and neck squamous cell carcinoma (HNSCC) progression. However, the mechanisms underlying these effects remain unclear. Therefore, we aimed to examine the mechanisms underlying the effects of DHA on tumor invasion and migration. Methods Human HNSCC cell lines CAL-27 and FaDu were exposed to varying DHA concentrations (0, 5, 20, and 80 μM) for 24 h. Cell proliferation, invasion, and migration were assessed using CCK8, transwell, and wound-healing assays, respectively. Quantitative real-time PCR, western blotting, and immunofluorescence were used to assess the expression levels of the target genes and proteins. Results DHA suppressed the invasion and migration of CAL-27 and FaDu cells. Additionally, miR-195-5p suppressed the invasion and migration of HNSCC cells. This study revealed significant differences in the expression of miR-195-5p and TENM2 between clinical samples and multiple public databases. DHA treatment and miR-195-5p overexpression significantly reduced TENM2 expression in HNSCC cells, which suggested that miR-195-5p overexpression enhanced the inhibitory effect of DHA on TENM2. Conclusions This study provides the first evidence that DHA inhibits cell invasion and migration by regulating the miR-195-5p/TENM2 axis in HNSCC cells, suggesting it as a potentially effective treatment strategy for HNSCC.

Qi F, Wang Y, Yu B, Li F. Identification of RECK as a protective prognostic indicator and a tumor suppressor through regulation of the ERK/MAPK signaling pathway in gastric cancer. J Transl Med 2023; 21:766. [PMID: 37904179 PMCID: PMC10614389 DOI: 10.1186/s12967-023-04644-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Accepted: 10/20/2023] [Indexed: 11/01/2023] Open
Abstract
BACKGROUND Gastric cancer (GC) ranks as the fifth most common cancer worldwide and is characterized by its significant heterogeneity and unfavorable prognosis. Thus, identifying efficient prognostic factors and understanding the underlying molecular mechanisms in GC are essential for improving patient outcomes. In this study, we aimed to investigate the role of RECK (reversion-inducing cysteine-rich protein with Kazal motifs) in the prognostic significance and molecular mechanisms of its biological function in GC. METHODS Multiple bioinformatics strategies were performed to detect the potential functions and prognostic efficiency of RECK in GC. Rescue experiments revealed that the molecular mechanism by which RECK in inhibited tumor proliferation, migration, and invasion was mediated by ERK/MAPK signaling in AGS and HGC-27 cells. Using integrated bioinformatics analysis and western blot assay, we investigated the potential interaction between CALD1 and RECK. RESULTS Our findings revealed significantly decreased RECK expression in GC samples compared to normal samples and RECK was identified as a promising predictor for the prognosis of GC patients. Moreover, upregulation of RECK demonstrated a distinctly positive association with a high-immunity and low-metastasis microenvironment in GC. Mechanistically, the antitumour effects of RECK on hampering tumor cell growth, migration, and invasion were mediated by the ERK/MAPK signaling pathway. In addition, we also illustrated that RECK inhibited the phosphorylation of CALD1 mediated by decreased phosphorylation of ERK. CONCLUSIONS RECK is a promising prognostic biomarker and may shape a high-tumor-immunity and low-metastasis microenvironment in patients with GC. Moreover, RECK exerted its tumor-suppressive effects by the inactivation of ERK/MAPK signaling in GC cells.

Cancer Commun (Lond) 2023; 43:1071-1096. [PMID: 37718480 PMCID: PMC10565387 DOI: 10.1002/cac2.12487] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 08/13/2023] [Accepted: 09/11/2023] [Indexed: 09/19/2023] Open
Abstract
The advent of immunotherapy has significantly reshaped the landscape of cancer treatment, greatly enhancing therapeutic outcomes for multiple types of cancer. However, only a small subset of individuals respond to it, underscoring the urgent need for new methods to improve its response rate. Ferroptosis, a recently discovered form of programmed cell death, has emerged as a promising approach for anti-tumor therapy, with targeting ferroptosis to kill tumors seen as a potentially effective strategy. Numerous studies suggest that inducing ferroptosis can synergistically enhance the effects of immunotherapy, paving the way for a promising combined treatment method in the future. Nevertheless, recent research has raised concerns about the potential negative impacts on anti-tumor immunity as a consequence of inducing ferroptosis, leading to conflicting views within the scientific community about the interplay between ferroptosis and anti-tumor immunity, thereby underscoring the necessity of a comprehensive review of the existing literature on this relationship. Previous reviews on ferroptosis have touched on related content, many focusing primarily on the promoting role of ferroptosis on anti-tumor immunity while overlooking recent evidence on the inhibitory effects of ferroptosis on immunity. Others have concentrated solely on discussing related content either from the perspective of cancer cells and ferroptosis or from immune cells and ferroptosis. Given that both cancer cells and immune cells exist in the tumor microenvironment, a one-sided discussion cannot comprehensively summarize this topic. Therefore, from the perspectives of both tumor cells and tumor-infiltrating immune cells, we systematically summarize the current conflicting views on the interplay between ferroptosis and anti-tumor immunity, intending to provide potential explanations and identify the work needed to establish a translational basis for combined ferroptosis-targeted therapy and immunotherapy in treating tumors.

Abstract
Colorectal cancer (CRC) is a common tumor with high morbidity and mortality. The use of oxaliplatin (L-OHP) as a first-line treatment for CRC is limited due to chemoresistance. Growing evidence have revealed that the existence of cancer stem-like cells (CSLCs) is one of the important reasons for drug resistance and recurrence of cancers. Dihydroartemisinin (DHA), a derivative of artemisinin, has showed anticancer effects on a variety of malignancies, in addition to its antimalarial effects. However, the effect and mechanism of DHA on CSLCs and chemosensitivity in CRC cells remains unclear. In this study, we found that DHA inhibited cell viability in HCT116 and SW620 cells. Moreover, DHA decreased cell clonogenicity, and improved L-OHP sensitivity. Furthermore, DHA treatment attenuated tumor sphere formation, and the expressions of stem cell surface marker (CD133 and CD44) and stemness-associated transcription factor (Nanog, c-Myc, and OCT4). Mechanistically, the present findings showed that DHA inhibited of AKT/mTOR signaling pathway. The activation of AKT/mTOR signaling reversed DHA-decreased cell viability, clonogenicity, L-OHP resistance, tumor sphere, and expressions of stemness-associated protein in CRC. The inhibitory effect of DHA on tumorigenicity of CRC cells has also been demonstrated in BALB/c nude mice. In conclusion, this study revealed that DHA inhibited CSLCs properties in CRC via AKT/mTOR signaling, suggesting that DHA may be used as a potential therapeutic agent for CRC.

Novel Thioethers of Dihydroartemisinin Exhibiting Their Biological Activities. HETEROATOM CHEMISTRY 2023. [DOI: 10.1155/2023/6761186] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 02/11/2023]
Abstract
Eleven conjugates between dihydroartemisinin (DHA) with thiols containing both ether and thioether bonds were designed, synthesized by a two-step procedure including etherification and S-alkylation. Analysis of the NMR spectral data indicated that the dimer of DHA with thiols 6-mercaptopurine and 2-mercaptoimidazole was produced with yields of 31% and 62%, respectively. Furthermore, the tautomerization of thiol 5-methoxy-2-mercaptobenzimidazole led to the formation of a mixture of two isomers in which they might be interchangeable through a dynamic tautomeric equilibrium in the solution. Screening in vitro biological activities revealed that most of the synthesized conjugates showed good cytotoxic and anti-inflammatory activity, while three of them displayed α-glucosidase inhibitory activity. Notably, two conjugates 5d and 5e of DHA with thiols 2-mercaptopyrimidine and 2-mercaptobenzothiazole had an effect in all tested activities in which conjugate 5e is the most potent.

Abstract
Ten novel mitochondria-targeted dihydroartemisinin ether derivatives were designed, synthesized, and evaluated for antitumor activity against five cancer cell lines in vitro. Profoundly, compound D8-T (IC50 = 56.9 nM) showed the most potent antiproliferative activity against the T24 cells with low cytotoxicity in normal human umbilical vein endothelial cells. High-performance liquid chromatography analysis confirmed that D8-T targeted mitochondria 6.3-fold higher than DHA. ATP content assay demonstrated that D8-T decreased the ATP level of bladder cancer cells. The effect of D8-T on cell apoptosis was determined by flow cytometry and western blot of Bax and Bcl-2. Surprisingly, the results indicated that D8-T did not induce bladder cancer cell apoptosis. In contrast, the cell cycle analysis and western blot of CDK4, CDK6, cyclin D1, and p21 demonstrated that the cancer cell cycle was arrested at the G1 phase after D8-T treatment. Furthermore, the consistent results were received by RNA-seq assay. These promising findings implied that D8-T could serve as a great candidate against bladder cancer for further investigation.

Abstract
ABSTRACT Dihydroartemisinin (DHA) is an active form of artemisinin extracted from the traditional Chinese medicine Artemisia annua , which is used to treat malaria. Previous studies have shown that DHA has a therapeutic effect on pulmonary hypertension (PH), but its specific mechanism has not been fully elucidated. In this study, a hypoxia-induced PH mouse model was established and DHA was administered as a therapeutic intervention. We measured hemodynamics and right ventricular hypertrophy and observed hematoxylin and eosin staining of lung tissue sections, proving the therapeutic effect of DHA on PH. Furthermore, cell counting kit-8 and 5-ethynyl-2'-deoxyuridine (EdU) cell proliferation assay kit were performed to examine cell proliferation of pulmonary artery smooth muscle cells cultured in hypoxia or in normoxia. Transwell migration chamber assay was performed to examine cell migration of the same cell model. Consistent with the therapeutic effect in vivo, DHA inhibited hypoxia-induced cell proliferation and migration. Through high-throughput sequencing of mouse lung tissue, we screened embryonic lethal abnormal vision-like 2 (ELAVL2) as a key RNA binding protein in PH. Mechanistically, DHA inhibited the proliferation and migration of pulmonary artery smooth muscle cells by promoting the expression of ELAVL2 and regulating the miR-503/PI3K/AKT pathway. The binding relationship between ELAVL2 and pre-miR-503 was verified by RNA binding protein immunoprecipitation assay. In conclusion, we first propose that DHA alleviates PH through the ELAVL2/miR-503/PI3K/AKT pathway, which may provide a basis for new therapeutic strategies of PH.

Dihydroartemisinin improves hypercholesterolemia in ovariectomized mice via enhancing vectorial transport of cholesterol and bile acids from blood to bile. Bioorg Med Chem 2022; 53:116520. [PMID: 34847494 DOI: 10.1016/j.bmc.2021.116520] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Revised: 11/07/2021] [Accepted: 11/16/2021] [Indexed: 12/12/2022]
Abstract
The increase of concentrations of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in the serum of postmenopausal women is the important risk factor of the high morbidity of cardiovascular diseases of old women worldwide. To test the anti-hypercholesterolemia function of dihydroartemisinin (DHA) in postmenopausal women, ovariectomized (OVX) mice were generated, and DHA were administrated to OVX mice for 4 weeks. The blood and liver tissues were collected for biochemical and histological tests respectively. The mRNA and protein expression levels of genes related to metabolism and transport of cholesterol, bile acid and fatty acid in the liver or ileum were checked through qPCR and western blot. DHA could significantly reduce the high concentrations of TC and LDL-C in the serum and the lipid accumulation in the liver of ovariectomized mice. The expression of ABCG5/8 was reduced in liver of OVX mice, and DHA could up-regulate the expression of them. Genes of transport proteins for bile salt transport from blood to bile, including Slc10a1, Slco1b2 and Abcb11, were also significantly up-regulated by DHA. DHA also down-regulated the expression of Slc10a2 in the ileum of OVX mice to reduce the absorption of bile salts. Genes required for fatty acid synthesis and uptake, such as Fasn and CD36, were reduced in the liver of OVX mice, and DHA administration could significantly up-regulate the expression of them. These results demonstrated that DHA could improve hypercholesterolemia in OVX mice through enhancing the vectorial transport of cholesterol and bile acid from blood to bile.

[PMID: 34202028 PMCID: PMC8301091 DOI: 10.3390/biology10070584] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Revised: 06/10/2021] [Accepted: 06/21/2021] [Indexed: 12/29/2022]
Abstract
Simple Summary In this study, we propose a copy number variation (CNV) detection method called CIRCNV, which is based on a circular profile of the read depth from sequencing data. The proposed method is an extended version of our previously developed method CNV-LOF. The main difference of CIRCNV from CNV-LOF lies in its two new features: (1) it transfers the read depth profile from a line shape to a circular shape via a polar coordinate transformation to generate a meaningful two-dimensional dataset for CNV analysis and promote fairness between the ends and middle part of the genome, and (2) it performs two rounds of CNV declaration via estimating tumor purity and recovering the truth circular RD profile. We test and evaluate the performance of CIRCNV via conducting simulation studies and real sequencing tumor sample applications. The experimental results show that CIRCNV outperforms peer methods with respect to sensitivity, precision, and the F1-score. The experiments prove that the proposed method is a reliable and effective tool in the field of variation analysis of tumor genomes. Abstract Copy number variation (CNV) is a common type of structural variation in the human genome. Accurate detection of CNVs from tumor genomes can provide crucial information for the study of tumor genesis and cancer precision diagnosis. However, the contamination of normal genomes in tumor genomes and the crude profiles of the read depth make such a task difficult. In this paper, we propose an alternative approach, called CIRCNV, for the detection of CNVs from sequencing data. CIRCNV is an extension of our previously developed method CNV-LOF, which uses local outlier factors to predict CNVs. Comparatively, CIRCNV can be performed on individual tumor samples and has the following two new features: (1) it transfers the read depth profile from a line shape to a circular shape via a polar coordinate transformation, in order to improve the efficiency of the read depth (RD) profile for the detection of CNVs; and (2) it performs a second round of CNV declaration based on the truth circular RD profile, which is recovered by estimating tumor purity. We test and validate the performance of CIRCNV based on simulation and real sequencing data and perform comparisons with several peer methods. The results demonstrate that CIRCNV can obtain superior performance in terms of sensitivity and precision. We expect that our proposed method will be a supplement to existing methods and become a routine tool in the field of variation analysis of tumor genomes.
