Abstract
Emodin has been reported to fulfill an important function in suppressing the vicious outcome of liver cancer. We aimed to elucidate the partial underlying molecular mechanism of emodin in inhibiting liver cancer, and we applied miRNA-sequence analysis and corresponding molecular functional experiments to find that the inhibitory effect of emodin on liver cancer was partly mediated by cellular autophagy through the miR-371a-5p/PTEN axis. The expression level of miR-371a-5p was down-regulated after emodin treatment in liver cancer cell lines (LCCLs). Restoring the expression level of miR-371a-5p attenuated the suppression of emodin on LCCLs. Additionally, we performed the prediction in relevant online databases and found that PTEN might functioned as a downstream target of miR-371a-5p to participate in the regulation on the above process. What's more, the detection of autophagy-related protein markers showed that LC3II was elevated accompanied by the decreased P62. The above results revealed that PTEN functioned as a key target to regulate the autophagy in the process where emodin inhibited the malignant outcome of LCCLs via miR-371a-5p, which further provided a theoretical basis for the application of traditional Chinese medicine (TCM) on clinical tumors.

JOURNAL OF HEALTHCARE ENGINEERING 2021; 2021:3506559. [PMID: 34630982 PMCID: PMC8494543 DOI: 10.1155/2021/3506559] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Revised: 08/05/2021] [Accepted: 09/08/2021] [Indexed: 02/05/2023]
Abstract
Goiter is thyroid enlargement, in China, Sageretia hamosa Brongn (SHB) can be used to treat goiter, but it has not been reported. Therefore, data analytics of SHB prescription on thyroid were explored in this study to provide a theoretical support for SHB in the treatment of goiter. In this study, rat in goiter model was constructed by using propylthiouracil (PTU) and treated with SHB prescription. Thyroid function about the triiodothyronine (T3), free thyroxine (T4), free triiodothyronine (FT3), free thyroxine (FT4), and thyroid-stimulating hormone (TSH) were measured by ELISA; thyroid coefficient was calculated after weighed thyroid; and HE staining was applied to assess the morphology of thyroid tissue. miRNA microarrays were employed to detect miRNA expression in thyroid tissue of rats. Expression of miR-511-3p was measured by RT-qPCR; expression of proteins (PTEN and apoptosis-related proteins) was tested by western blotting; relationship between miR-511-3p and PTEN was investigated by dual luciferase reporter gene assay; cell viability rate was determined by CCK-8; and cell cycle distribution and apoptosis rate were detected by flow cytometry. The results showed that SHB prescription ameliorated goiter and downregulated miR-511-3p. miR-511-3p targeted PTEN in thyroid cells and PTEN negatively regulated the activation of PI3K/Akt pathway. Furthermore, the inhibition of apoptosis in thyroid cells caused by the overexpression of miR-511-3p or the activation of PI3K/Akt pathway was reversed by treatment of SHB prescription, inhibition of miR-511-3p, or overexpression of PTEN. In conclusion, SHB prescription promoted apoptosis of thyroid through decreased miR-511-3p and regulated PTEN/PI3K/Akt pathway, it might suggest possible medical applications.

High-Throughput Sequencing Reveals the Differential MicroRNA Expression Profiles of Human Gastric Cancer SGC7901 Cell Xenograft Nude Mouse Models Treated with Traditional Chinese Medicine Si Jun Zi Tang Decoction. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:6119212. [PMID: 34457026 PMCID: PMC8387168 DOI: 10.1155/2021/6119212] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Revised: 07/14/2021] [Accepted: 08/04/2021] [Indexed: 12/14/2022]
Abstract
Objective. The present study aimed to investigate the potential mechanism underlying the antitumor effect of Si Jun Zi Tang (SJZT) decoction on gastric cancer. Methods. Twelve human gastric cancer SGC7901 cell xenograft nude mouse models were established. The mice were randomly divided into the Model group and SJZT group. SJZT exerted significant antitumor effects after 21 days of decoction administration. High-throughput sequencing was used to analyze the microRNA (miRNA) expression profiles of tumor tissues. Bioinformatics analysis was performed to provide further information regarding the differentially expressed miRNAs. Five representative differentially expressed miRNAs and four predicted target genes were further validated using quantitative real-time reverse transcription PCR (qRT-PCR). Results. We identified 33 miRNAs that were differentially expressed in the SJZT group compared with the Model group. Among them, 32 miRNAs were upregulated and 1 miRNA was downregulated. Bioinformatic analysis showed that most of miRNAs acted as tumor suppressors and their target genes participated in multiple signaling pathways, including the PI3K/Akt signaling pathway, microRNAs in cancer, and Wnt signaling pathway. The qRT-PCR result confirmed that miR-223-3p, miR-205-5p, miR-147b-3p, and miR-223-5p were overexpressed and their respective paired target genes FUT9, POU2F1, MUC4, and RAB14 mRNA were obviously downregulated in the SJZT group compared with those in the Model group. Network analysis revealed that miR-223-3p and miR-205-5p shared two targets POU2F1 (encoding POU class 2 homeobox 1) and FUT9 (encoding fucosyltransferase 9), suggesting they have a common role in certain pathways. Conclusion. This study provided novel insights into the anticancer mechanism of SJZT against gastric cancer, which might be partly related to the modulation of miRNA expression and their target pathways in tumors.

ACTA ACUST UNITED AC 2021; 54:e10222. [PMID: 33470388 PMCID: PMC7814303 DOI: 10.1590/1414-431x202010222] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Accepted: 10/12/2020] [Indexed: 12/12/2022]
Abstract
Platycodin D (PD) is a major constituent of Platycodon grandiflorum and has multiple functions in disease control. This study focused on the function of PD in bladder cancer cell behaviors and the molecules involved. First, we administered PD to the bladder cancer cell lines T24 and 5637 and the human uroepithelial cell line SV-HUC-1. Cell viability and growth were evaluated using MTT, EdU, and colony formation assays, and cell apoptosis was determined using Hoechst 33342 staining and flow cytometry. The microRNAs (miRNAs) showing differential expression in cells before and after PD treatment were screened. Moreover, we altered the expression of miR-129-5p and PABPC1 to identify their functions in bladder cancer progression. We found that PD specifically inhibited the proliferation and promoted the apoptosis of bladder cancer cells; miR-129-5p was found to be partially responsible for the cancer-inhibiting properties of PD. PABPC1, a direct target of miR-129-5p, was abundantly expressed in T24 and 5637 cell lines and promoted cell proliferation and suppressed cell apoptosis. In addition, PABPC1 promoted the phosphorylation of PI3K and AKT in bladder cancer cells. Altogether, PD had a concentration-dependent suppressive effect on bladder cancer cell growth and was involved in the upregulation of miR-129-5p and the subsequent inhibition of PABPC1 and inactivation of PI3K/AKT signaling.
