Recent Pat Anticancer Drug Discov 2024; 19:543-555. [PMID: 38305308 DOI: 10.2174/0115748928283132240103073039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 11/30/2023] [Accepted: 12/07/2023] [Indexed: 02/03/2024]
Abstract
BACKGROUND Saponin of Schizocapsa plantaginea Hance I (SSPH I).a bioactive saponin found in Schizocapsa plantaginea, exhibits significant anti-proliferation and antimetastasis in lung cancer. OBJECTIVE To explore the anti-metastatic effects of SSPH I on non-small cell lung cancer (NSCLC) with emphasis on epithelial-mesenchymal transition (EMT) both in vitro and in vivo. METHODS The effects of SSPH I at the concentrations of 0, 0.875,1.75, and 3.5 μM on A549 and PC9 lung cancer cells were evaluated using colony formation assay, CCK-8 assay, transwell assay and wound-healing assay. The actin cytoskeleton reorganization of PC9 and A549 cells was detected using the FITC-phalloidin fluorescence staining assay. The proteins related to EMT (N-cadherin, E-cadherin and vimentin), p- PI3K, p- AKT, p- mTOR and p- ERK1/2 were detected by Western blotting. A mouse model of lung cancer metastasis was established by utilizing 95-D cells, and the mice were treated with SSPH I by gavage. RESULTS The results suggested that SSPH I significantly inhibited the migration and invasion of NSCLC cells under a non-cytotoxic concentration. Furthermore, SSPH I at a non-toxic concentration of 0.875 μM inhibited F-actin cytoskeleton organization. Importantly, attenuation of EMT was observed in A549 cells with upregulation in the expression of epithelial cell marker E-cadherin and downregulation of the mesenchymal cell markers vimentin as well as Ncadherin. Mechanistic studies revealed that SSPH I inhibited MAPK/ERK1/2 and PI3K/AKT/mTOR signaling pathways. CONCLUSION SSPH I inhibited EMT, migration, and invasion of NSCLC cells by suppressing MAPK/ERK1/2 and PI3K/AKT/mTOR signaling pathways, suggesting that the natural compound SSPH I could be used for inhibiting metastasis of NSCLC.

[PMID: 36670776 PMCID: PMC9854751 DOI: 10.3390/ani13020236] [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: 11/28/2022] [Revised: 12/30/2022] [Accepted: 01/03/2023] [Indexed: 01/11/2023] Open
Abstract
CircRNAs are essential in regulating follicle growth and development and the female reproductive system at multiple levels. However, the molecular mechanism by which circRNAs regulate reproduction in sheep is unclear and requires further exploration. In this study, RNA sequencing was performed to reveal the circRNA expression profiles in the ovaries of Cele black sheep and Hetian sheep during estrus. Analysis of the number of circRNAs in their host genes revealed that 5031 genes could produce 20,835 circRNAs. Among the differentially expressed circRNAs (DEcircRNA), 75 were upregulated, and 105 were downregulated. Functional enrichment analysis showed that the host genes of DEcircRNA were involved in several pathways, including the MAPK and Hippo signaling pathway. In addition, we constructed a subnetwork of competitive endogenous RNA (ceRNA) containing 4 mRNAs, 4 microRNAs (miRNAs), and 10 circRNAs, potentially related to follicle development. Functional circRNAs (e.g., novel_circ_0003851, novel_circ_0015526, novel_circ_0008117) were found to act as ceRNAs for follicle growth and development-related mRNAs (CUEDC1, KPNB1, ZFPM2) by sponging functional miRNAs (miR-29a, miR-29b, miR-17-5p). Finally, through an RNA pull-down assay, oar-miR-125b was selected and confirmed as the target miRNA of novel-circ-0041512. We analyzed the overall expression of circRNAs in sheep ovaries. Further, we explored the potential mechanisms underlying the circRNA functions, providing a theoretical basis for the genetic progress of reproductive traits in sheep.

Abstract
Non-small-cell lung carcinoma (NSCLC) is considered to be a fatal disease and characterized by a poor prognosis. Long non-coding RNAs (lncRNAs) have been reported to act as biomarkers and therapeutic targets in solid tumors. However, the expression of lncRNAs and their clinical relevance in NSCLC remain undetermined. The gene expression data profiled in The Cancer Genome Atlas and Gene Expression Omnibus (GSE81089) were employed to screen differentially expressed lncRNAs in NSCLC. LINC02678 was found to be upregulated in NSCLC and exhibited hypomethylation of the promoter region in NSCLC tissues. LINC02678 (also called RP11-336A10.5) was associated with poorer overall survival and relapse-free survival in NSCLC patients. In vitro models of gain- and loss-of-function demonstrated that LINC02678 promotes NSCLC progression by promoting NSCLC cell proliferation and cell cycle progression, as well as inducing NSCLC cell migration, invasion and epithelial-mesenchymal transition. LINC02678 was primarily located in the nucleus and could bind with the enhancer of zeste homolog 2 (EZH2). Moreover, we found that LINC02678 knockdown impaired the occupancy capacity of EZH2 and trimethylation of lysine 27 on histone 3 (H3K27me3) at the promoter region of cyclin dependent kinase inhibitor 1B (CDKN1B) and E-cadherin, as confirmed by ChIP-qPCR. A mouse transplantation model further demonstrated that LINC02678 could promote the tumorigenic and metastatic capacities of NSCLC cells. We identified LINC02678 as a tumor promoter in NSCLC, which enhanced the growth and metastasis of NSCLC cells by binding with EZH2, indicating that LINC02678 may serve as a potential biomarker for cancer diagnosis and treatment.

Long non‑coding RNA MIR4713HG aggravates malignant behaviors in oral tongue squamous cell carcinoma via binding with microRNA let‑7c‑5p. Int J Mol Med 2021; 47:84.

Abstract
Oral tongue squamous cell carcinoma (OTSCC) is one of the most aggressive pathological types of head and neck squamous cell carcinoma, and presents with rapid local invasion and metastasis. The present study confirmed that the long non‑coding (lnc) RNA MIR4713HG was markedly upregulated in both OTSCC tissues and cell lines and associated with poor survival. The present study performed a series of experiments to investigate the impact of MIR4713HG on OTSCC and revealed that upregulation of MIR4713HG had a crucial role in promoting cell proliferation and metastasis of OTSCC cell lines both in vitro and in vivo. By applying bioinformatics analyses, micro RNA let‑7c‑5p was observed to physically bind with MIR4713HG, and the knockdown of let‑7c‑5p could counteract the influence of MIR4713HG on OTSCC. Furthermore, the present study demonstrated that let‑7c‑5p performed its regulating role in OTSCC via affecting the expression level of transmembrane channel like 7 (TMC7). In conclusion, the present study demonstrated that lncRNA MIR4713HG acted as a pro‑tumor factor facilitating cell proliferation and metastasis of OTSCC via affecting the let‑7c‑5p/TMC7 signaling pathway, which presents as a promising therapeutic target in OTSCC.

[PMID: 33791301 PMCID: PMC8005613 DOI: 10.3389/fcell.2021.643522] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Accepted: 02/04/2021] [Indexed: 01/06/2023] Open
Abstract
Osteosarcoma (OS) that mainly occurs during childhood and adolescence is a devastating disease with poor prognosis presented by extreme metastases. Recent studies have revealed that liver receptor homolog 1 (LRH-1) plays a vital role in the metastasis of several human cancers, but its role is unknown in the metastasis of OS. In this study, Gene Ontology (GO) enrichment analyses based on high-throughput RNA-seq data revealed that LRH-1 acted a pivotal part in the positive regulation of cell migration, motility, and angiogenesis. Consistently, LRH-1 knockdown inhibited the migration of human OS cells, which was concurrent with the downregulation of mesenchymal markers and the upregulation of epithelial markers. In addition, short hairpin RNAs (shRNAs) targeting LRH-1 inactivated transforming growth factor beta (TGF-β) signaling pathway. LRH-1 knockdown inhibited human umbilical vein endothelial cell (HUVEC) proliferation, migration, and tube formation. Vascular endothelial growth factor A (VEGFA) expression was also downregulated after LRH-1 knockdown. Immunohistochemistry (IHC) revealed that the expression of LRH-1 protein was significantly higher in tumor tissues than in normal bone tissues. We found that high LRH-1 expression was associated with poor differentiation and advanced TNM stage in OS patients using IHC. Based on The Cancer Genome Atlas (TCGA) database, high LRH-1 expression predicts poor survival in lung squamous cell carcinoma (LUSC), kidney renal papillary cell carcinoma (KIRP), and pancreatic adenocarcinoma (PAAD). The downregulation of LRH-1 significantly hindered the migration and motility of LUSC cells. Using multi-omic bioinformatics, the positive correlation between LRH-1- and EMT-related genes was found across these three cancer types. GO analysis indicated that LRH-1 played a vital role in “blood vessel morphogenesis” or “vasculogenesis” in KIRP. Our results indicated that LRH-1 plays a tumor-promoting role in human OS, could predict the early metastatic potential, and may serve as a potential target for cancer therapy.
