SIVA-1 interaction with PCBP1 serves as a predictive biomarker for cisplatin sensitivity in gastric cancer and its inhibitory effect on tumor growth in vivo. J Cancer 2024; 15:4301-4312. [PMID: 38947376 PMCID: PMC11212092 DOI: 10.7150/jca.92963] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Accepted: 05/30/2024] [Indexed: 07/02/2024] Open
Abstract
Background: SIVA-1 has been reported to play a key role in cell apoptosis and gastric cancer (GC) chemoresistance in vitro. Nevertheless, the clinical significance of SIVA-1 in GC chemotherapy remains unclear. Methods and results: Immunohistochemistry and histoculture drug response assays were used to determine SIVA-1 expression and the inhibition rate (IR) of agents to GC and to further analyze the relationship between these two phenomena. Additionally, cisplatin (DDP)-resistant GC cells were used to elucidate the role and mechanism of SIVA-1 in vivo. The results demonstrated that SIVA-1 expression was positively correlated with the IR of DDP to GC but not with those of 5-fluorouracil (5-FU) or adriamycin (ADM). Furthermore, SIVA-1 overexpression with DDP treatment synergistically inhibited tumor growth in vivo by increasing PCBP1 and decreasing Bcl-2 and Bcl-xL expression. Conclusions: Our study demonstrated that SIVA-1 may serve as an indicator of the GC sensitivity to DDP, and the mechanism of SIVA-1 in GC resistance to DDP was preliminarily revealed.

Mutation of SIVA, a candidate metastasis gene identified from clonally related bilateral breast cancers, promotes breast cancer cell spread in vitro and in vivo. PLoS One 2024; 19:e0302856. [PMID: 38722955 PMCID: PMC11081324 DOI: 10.1371/journal.pone.0302856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Accepted: 04/12/2024] [Indexed: 05/13/2024] Open
Abstract
Metastasis is the most dreaded outcome after a breast cancer diagnosis, and little is known regarding what triggers or promotes breast cancer to spread distally, or how to prevent or eradicate metastasis effectively. Bilateral breast cancers are an uncommon form of breast cancers. In our study, a percentage of bilateral breast cancers were clonally related based on copy number variation profiling. Whole exome sequencing and comparative sequence analysis revealed that a limited number of somatic mutations were acquired in this "breast-to-breast" metastasis that might promote breast cancer distant spread. One somatic mutation acquired was SIVA-D160N that displayed pro-metastatic phenotypes in vivo and in vitro. Over-expression of SIVA-D160N promoted migration and invasion of human MB-MDA-231 breast cancer cells in vitro, consistent with a dominant negative interfering function. When introduced via tail vein injection, 231 cells over-expressing SIVA-D160N displayed enhanced distant spread on IVIS imaging. Over-expression of SIVA-D160N promoted invasion and anchorage independent growth of mouse 4T1 breast cancer cells in vitro. When introduced orthotopically via mammary fat pad injection in syngeneic Balb/c mice, over-expression of SIVA-D160N in 4T1 cells increased orthotopically implanted mammary gland tumor growth as well as liver metastasis. Clonally related bilateral breast cancers represented a novel system to investigate metastasis and revealed a role of SIVA-D160N in breast cancer metastasis. Further characterization and understanding of SIVA function, and that of its interacting proteins, may elucidate mechanisms of breast cancer metastasis, providing clinically useful biomarkers and therapeutic targets.

SIVA-1 enhances acquired chemotherapeutic drug resistance of gastric cancer in vivo by regulating the ARF/MDM2/p53 pathway. Heliyon 2024; 10:e24394. [PMID: 38312638 PMCID: PMC10834467 DOI: 10.1016/j.heliyon.2024.e24394] [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: 03/20/2023] [Revised: 01/07/2024] [Accepted: 01/08/2024] [Indexed: 02/06/2024] Open
Abstract
SIVA-1 has been shown to affect apoptotic processes in various different cell lines, and SIVA-1 significantly contributes to the decreased responsiveness of cancer cells to some chemotherapy agents. However, whether SIVA-1 has potential application in gastric cancer remains unknown. Therefore, the objective of this investigation was to clarify the distinct function of SIVA-1 in chemotherapeutic drug resistance within a living murine model with gastric malignancy, and initially elucidate the underlying mechanisms. In an established multidrug-resistant gastric cancer xenograft mouse model, lentivirus, named Lv-SIVA-1, was injected into xenograft tumors, and increased the mRNA and protein expression of endogenous SIVA-1 in tumors. Immunohistochemical assays of xenograft tumor showed that SIVA-1 was significantly upregulated, and the protein expression levels of SIVA-1 were highly increased, as detected by Western blotting. In addition, we detected the role of SIVA-1 in cell proliferation and cell apoptosis in gastric cancer cells by TUNEL and found that SIVA-1 decreased tumor cell apoptosis and promoted tumor growth in vivo. Using a TMT assay between tumor tissues of experimental and control groups, differentially expressed proteins were examined and three potential biomarkers of multidrug resistance (ARF, MDM2, and p53) were screened. We further investigated the molecular mechanism by which SIVA-1 played an efficient role against chemotherapies and found that overexpressed SIVA-1 leads to increased ARF and MDM2 expression and suppressed expression of p53 in tumor tissue. In conclusion, SIVA-1 plays a significant role in the multidrug resistance of gastric tumors. In addition, overexpressed SIVA-1 positively regulates cell proliferation, adjusts cycle progression, and reduces the response to drug treatment for gastric cancer in an ARF/MDM2/p53-dependent manner. This novel research provides a basis for chemical management of gastric cancer through regulation of SIVA-1 expression.

Inhibition of murine colorectal cancer metastasis by targeting M2-TAM through STAT3/NF-kB/AKT signaling using macrophage 1-derived extracellular vesicles loaded with oxaliplatin, retinoic acid, and Libidibia ferrea. Biomed Pharmacother 2023; 168:115663. [PMID: 37832408 DOI: 10.1016/j.biopha.2023.115663] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 10/05/2023] [Accepted: 10/05/2023] [Indexed: 10/15/2023] Open
Abstract
Colorectal cancer is still unmanageable despite advances in target therapy. However, extracellular vesicles (EVs) have shown potential in nanomedicine as drug delivery systems, especially for modulating the immune cells in the tumor microenvironment (TME). In this study, M1 Macrophage EVs (M1EVs) were used as nanocarriers of oxaliplatin (M1EV1) associated with retinoic acid (M1EV2) and Libidibia ferrea (M1EV3), alone or in combination (M1EV4) to evaluate their antiproliferative and immunomodulatory potential on CT-26 and MC-38 colorectal cancer cell lines and prevent metastasis in mice of allograft and peritoneal colorectal cancer models. Tumors were evaluated by qRT-PCR and immunohistochemistry. The cell death profile and epithelial-mesenchymal transition process (EMT) were analyzed in vitro in colorectal cancer cell lines. Polarization of murine macrophages (RAW264.7 cells) was also carried out. M1EV2 and M1EV3 used alone or particularly M1EV4 downregulated the tumor progression by TME immunomodulation, leading to a decrease in primary tumor size and metastasis in the peritoneum, liver, and lungs. STAT3, NF-kB, and AKT were the major genes downregulated by of M1EV systems. Tumor-associated macrophages (TAMs) shifted from an M2 phenotype (CD163) to an M1 phenotype (CD68) reducing levels of IL-10, TGF-β and CCL22. Furthermore, malignant cells showed overexpression of FADD, APAF-1, caspase-3, and E-cadherin, and decreased expression of MDR1, survivin, vimentin, and PD-L1 after treatment with systems of M1EVs. The study shows that EVs from M1 antitumor macrophages can transport drugs and enhance their immunomodulatory and antitumor activity by modulating pathways associated with cell proliferation, migration, survival, and drug resistance.

Abstract
Chemoresistance limits cisplatin (DDP)-mediated treatment for gastric cancer (GC). Circular RNA (circRNA) acts an important role in chemoresistance. However, the underlying mechanism of circPDSS1 regulating DDP sensitivity in GC remains unclear. The expression patterns of circPDSS1, miR-515-5p and integrin subunit alpha 11 (ITGA11) were analyzed by qRT-PCR. Protein expression was checked by Western blotting analysis. Cell viability was investigated by 3-(4,5-dimethylthazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Cell proliferation was evaluated by colony formation assay and 5-ethynyl-2'-deoxyuridine (EdU) assay. The analysis of cell apoptosis, migration and invasion was performed by flow cytometry analysis and transwell assays. Dual-luciferase reporter assay and RNA immunoprecipitation assay were conducted to identify the associations among circPDSS1, miR-515-5p and ITGA11. In vivo assay was implemented using a xenograft mouse model assay. CircPDSS1 and ITGA11 expression were significantly upregulated, whereas miR-515-5p was downregulated in DDP-resistant GC tissues and cells in comparison with controls. CircPDSS1 depletion reduced DDP resistance, cell proliferation, migration and invasion but induced cell apoptosis in DDP-resistant GC cells. CircPDSS1 directly bound to miR-515-5p. CircPDSS1-mediated actions were dependent on the regulation of miR-515-5p. Besides, miR-515-5p was associated with ITGA11, and circPDSS1 regulated ITGA11 expression by binding to miR-515-5p. Overexpression of miR-515-5p improved DDP sensitivity owing to the downregulation of ITGA11. Further, circPDSS1 mediated DDP sensitivity by regulating miR-515-5p and ITGA11 in vivo. CircPDSS1 conferred DDP resistance through the miR-515-5p/ITGA11 axis in GC cells.

Abstract
OBJECTIVES Nephrotic syndrome is a common disease of the urinary system. The aim of this study is to explore the effect of astragalus polysaccharides (APS) on multidrug resistance gene 1 (MDR1) and P-glycoprotein 170 (P-gp170) in adriamycin nephropathy rats and the underlying mechanisms. METHODS A total of 72 male Wistar rats were divided into a control group, a model group, an APS low-dose group, an APS high-dose group, an APS+micro RNA (miR)-16 antagomir group and an APS+miR-16 antagomir control group, with 12 rats in each group. Urine protein (UP) was detected by urine analyzer, and serum cholesterol (CHOL), albumin (ALB), blood urea nitrogen (BUN), and creatinine (SCr) were detected by automatic biochemical analyzer; serum interleukin-6 (IL-6), IL-1β, tumor necrosis factor α (TNF-α) levels were detected by ELISA kit; the morphological changes of kidney tissues were observed by HE staining; the levels of miR-16 and MDR1 mRNA in kidney tissues were detected by real-time RT-PCR; the expression levels of NF-κB p65, p-NF-κB p65, and P-gp170 protein in kidney tissues were detected by Western blotting; and dual luciferase was used to verify the relationship between miR-16 and NF-κB. RESULTS The renal tissue structure of rats in the control group was normal without inflammatory cell infiltration. The renal glomeruli of rats in the model group were mildly congested, capillary stenosis or occlusion, and inflammatory cell infiltration was obvious. The rats in the low-dose and high-dose APS groups had no obvious glomerular congestion, the proliferation of mesangial cells was significantly reduced, and the inflammatory cells were reduced. Compared with the high-dose APS group and the APS+miR-16 antagomir control group, there were more severe renal tissue structure damages in the APS + miR-16 antagomir group. Compared with the control group, the levels of UP, CHOL, BUN, SCr, IL-6, IL-1β, TNF-α, and MDR1 mRNA, and the protein levels of p-NF-κB p65 and P-gp170 in the model group were significantly increased (all P<0.05); the levels of ALB and miR-16 were significantly decreased (both P<0.05). Compared with the model group, the levels of UP, CHOL, BUN, SCr, IL-6, IL-1β, TNF-α, and MDR1 mRNA, and the protein levels of pNF-κB p65 and P-gp170 in the low-dose and high-dose APS groups were significant decreased (all P<0.05); and the levels of ALB and miR-16 were significantly increased (both P<0.05). Compared with APS+miR-16 antagomir control group, the UP, CHOL, BUN, SCr, IL-6, IL-1β, and TNF-α levels, MDR1 mRNA, and the protein levels of p-NF-κB p65 and P-gp170 were significantly increased (all P<0.05). The levels of ALB and miR-16 were significantly decreased in the APS+miR-16 antagomir group compared with the APS+miR-16 antagomir control group (both P<0.05). CONCLUSIONS APS can regulate the miR-16/NF-κB signaling pathway, thereby affecting the levels of MDR1 and P-gp170, and reducing the inflammation in the kidney tissues in the adriamycin nephropathy rats.

Abstract
Background Gastric carcinoma (GC) ranks the fifth most common cancer worldwide, with high incidence and mortality rates. Numerous microRNAs (miRNAs), including miR-654-5p, have been implicated in the pathophysiological processes of tumorigenesis. Nevertheless, the mechanism of miR-654-5p in GC is unclear. Objectives Our study is devoted to exploring the function and molecular mechanism of miR-654-5p on the malignant cell behaviors of GC. Methods The gene expression was detected by reverse transcription quantitative polymerase chain reaction. GC cell proliferation and motion were assessed by colony formation assay and transwell assay. The binding capacity between miR-654-5p and G protein-regulated inducer of neurite outgrowth 1 (GPRIN1) was explored by luciferase reporter and RNA pulldown assays. The protein levels were detected by Western blotting. Results miR-654-5p expression was higher in GC cells and tissues than control cells and tissues. miR-654-5p promoted GC cell growth and motion. Moreover, our findings showed that miR-654-5p was bound with GPRIN1. Importantly, downregulation of GPRIN1 rescued the inhibitory influence of miR-654-5p knockdown on GC cell malignant behaviors. Additionally, miR-654-5p activated the nuclear factor kappa-B (NF-κB) pathway by regulation of GPRIN1. Conclusions miR-654-5p facilitated cell proliferation, migration, and invasion in GC via targeting the GPRIN1 to activate the NF-κB pathway.

Abstract
The cellular resistance of tumors is a major obstacle for successful tumor therapy. Cluster of differentiation (CD)133 plays an important role in the regulation of drug resistance in gastric and colon cancers. However, its effect on chemotherapeutic sensitivity in adenoid cystic carcinoma (ACC) has not been fully explored. The present study discussed the specific role of CD133 in ACC drug-resistant sensitive cells. KOA-1 cells were treated with 5-fluorouracil (5-FU) and pingyangmycin (PYM) to form drug-resistant cell lines. A Cell Counting Kit-8 assay was used to detect the cell survival rate. Cell invasion was measured using a Transwell assay. The expression levels of CD133 were detected by reverse transcription-quantitative (RT-q) PCR. The expression levels of drug-resistant mRNAs and proteins were detected by RT-qPCR and immunofluorescence analyses, respectively. The CD133 were inhibited by small interfering RNA technology. The survival rate and invasive ability of KOA-1 cells were increased following the induction of drug resistance. The expression levels of CD133, multidrug resistance protein (MDR)1 and multidrug resistance-associated protein (MRP)1 were significantly increased in drug-resistant cell lines. Knockdown of CD133 expression in the resistant cell lines, KOA-1/5-FU and KOA-1/PYM, decreased the survival rate and invasive ability. The expression levels of MDR1 and MRP1 were also significantly decreased. Knockdown of CD133 expression in ACC drug-resistant cells could inhibit the viability and invasion of tumors and enhance the sensitivity of drug-resistant cells to chemotherapeutic drugs.

Abstract
Drug resistance seriously limits the efficacy of chemotherapy drugs and hinders successful treatment in patients with gastric cancer. Endoplasmic reticulum (ER) and autophagy are recognized to be one of the mechanisms involving the drug resistance of gastric cancer. The mechanisms of action of JAK2/STAT3 pathway were investigated in AGS cells with drug resistance of 5-fluorouracil (5-FU) by corresponding inhibitors. We firstly analyzed the effects of JAK2/STAT3 inhibitor on the expression of drug resistance genes, autophagy markers, and ER stress-related markers on AGS/5-FU cells by Western blot. Whether JAK2/STAT3 pathway regulated the transcription of ATF6 was investigated through luciferase reporter assay. The expression of LC3B was detected by immunofluorescence assay. Next, ER stress inhibitor and ATF6 overexpression plasmid were respectively used to treat AGS/5-FU cells for analyzing whether JAK2/STAT3 pathway regulated ER stress. The results showed that JAK2 inhibitor or STAT3 inhibitor significantly altered the expression of these proteins and suppressed the activities of ATF6 promoter. Intriguingly, ATP6 overexpression could markedly reverse their effects. Moreover, similar effects to JAK2 inhibitor or STAT3 inhibitor appeared in ER stress inhibitor-treated group. These findings indicated that the involvement of JAK2/STAT3 pathway in regulating ER stress affected the 5-FU resistance of AGS cells and autophagy, which was mediated by ATF6. Targeting JAK2/STAT3 pathway could be a potential approach to decrease the 5-FU resistance of gastric cancer and enhance the sensitivity of gastric cancer to 5-FU. Additionally, our study offers new insights into the molecular mechanisms underlying the resistance of gastric cancer to 5-FU.
