Lv X, Xu G. Regulatory role of the transforming growth factor-β signaling pathway in the drug resistance of gastrointestinal cancers. World J Gastrointest Oncol 2021; 13:1648-1667. [PMID: 34853641 PMCID: PMC8603464 DOI: 10.4251/wjgo.v13.i11.1648] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Revised: 06/28/2021] [Accepted: 08/18/2021] [Indexed: 02/06/2023] Open
Abstract
Gastrointestinal (GI) cancer, including esophageal, gastric, and colorectal cancer, is one of the most prevalent types of malignant carcinoma and the leading cause of cancer-related deaths. Despite significant advances in therapeutic strategies for GI cancers in recent decades, drug resistance with various mechanisms remains the prevailing cause of therapy failure in GI cancers. Accumulating evidence has demonstrated that the transforming growth factor (TGF)-β signaling pathway has crucial, complex roles in many cellular functions related to drug resistance. This review summarizes current knowledge regarding the role of the TGF-β signaling pathway in the resistance of GI cancers to conventional chemotherapy, targeted therapy, immunotherapy, and traditional medicine. Various processes, including epithelial-mesenchymal transition, cancer stem cell development, tumor microenvironment alteration, and microRNA biogenesis, are proposed as the main mechanisms of TGF-β-mediated drug resistance in GI cancers. Several studies have already indicated the benefit of combining antitumor drugs with agents that suppress the TGF-β signaling pathway, but this approach needs to be verified in additional clinical studies. Moreover, the identification of potential biological markers that can be used to predict the response to TGF-β signaling pathway inhibitors during anticancer treatments will have important clinical implications in the future.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 271:113893. [PMID: 33524511 DOI: 10.1016/j.jep.2021.113893] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 01/17/2021] [Accepted: 01/25/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Zuojin Pill (ZJP) is a classic prescription composed of Coptis chinensis and Tetradium ruticarpum (A.Juss.) T.G.Hartley, which is often used in the treatment of digestive system diseases. AIM OF THIS STUDY The purpose of this study was to explore the therapeutic effect and potential mechanism of ZJP on chronic atrophic gastritis (CAG) induced by MNNG. MATERIALS AND METHODS The GES-1 and rat model of CAG was established by MNNG. Detection of cell viability, morphological changes and proliferation of GES-1 by CCK-8 and high content screening (HCS) assay. G-17, IL-8 and TNF-α in rat serum were detected by ELISA kit. The expression of related mRNA and protein on TGF-β1/PI3K/Akt signal axis were detected by RT-PCR and Western blot. RESULTS The results showed that ZJP could significantly improve the GES-1 damage induced by MNNG and improve the gastric histomorphology of CAG rats. The intervention of ZJP could significantly reduce the content of G-17 and inflammatory factors IL-8, TNF- α, IL-6 and IL-1β, inhibit the expression of TGF-β1, PI3K and their downstream signals p-Akt, p-mTOR, P70S6K, and promote the expression level of PTEN, LC3-II and Beclin-1. CONCLUSION ZJP has a good therapeutic effect on CAG induced by MNNG, which may be closely related to the inhibition of TGF-β1/PI3K/Akt signal pathway.

Anticancer Effect of the Ethyl Acetate Fraction from Orostachys japonicus on MDA-MB-231 Human Breast Cancer Cells through Extensive Induction of Apoptosis, Cell Cycle Arrest, and Antimetastasis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:8951510. [PMID: 31781282 PMCID: PMC6874866 DOI: 10.1155/2019/8951510] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/24/2019] [Revised: 09/05/2019] [Accepted: 09/18/2019] [Indexed: 01/24/2023]
Abstract
The antibreast cancer activities of the ethyl acetate fraction from Orostachys japonicus (OJEF) were investigated in MDA-MB-231 human breast cancer cells through WST assay, DAPI staining, flow cytometry analysis, and western blotting. OJEF effectively inhibited MDA-MB-231 cells by inducing apoptosis via intrinsic, extrinsic, and endoplasmic reticulum (ER) stress response pathways, cell cycle arrest at the G1/S phase, and antimetastasis including inhibition of tight junction, adherens junction, invasion, and migration. The MAPK family-mediated upstream signal transduction through p-p38 and p-ERK was considered to affect the downstream signal transduction including induction of apoptosis, cell cycle arrest, and antimetastasis. In conclusion, we executed an integrated study on the anticancer activities of OJEF, which extensively induced apoptosis, cell cycle arrest, and antimetastasis in estrogen-independent MDA-MB-231 human breast cancer cells known to be liable to metastasize.

MicroRNA-663 suppresses cell invasion and migration by targeting transforming growth factor beta 1 in papillary thyroid carcinoma. Tumour Biol 2015; 37:7633-44. [PMID: 26687649 DOI: 10.1007/s13277-015-4653-y] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2015] [Accepted: 12/14/2015] [Indexed: 01/07/2023] Open
Abstract
MicroRNA-663 (miR-663) has been detected in a large variety of tumor types; however, it still holds both tumor suppressive and oncogenic roles in different tumor types. The miRNA-CHIP microarray assay revealed downregulation of miR-663 in papillary thyroid carcinoma (PTC); however, the effect of miR-663 on PTC cell invasion and migration remains unknown. Accordingly, this study aimed to investigate the potential involvement of miR-663 in PTC. In this study, miR-663 expression level was measured via quantitative real-time PCR in 91 pairs of human PTC and adjacent normal tissues and in two human PTC cell lines. The effect of miR-663 on PTC cell invasion and migration were studied by transwell and wound healing assays. In addition, the miR-663 target was searched and the underlying mechanism was clarified by reporter assay and rescue experiment. The current study confirmed that miR-663 expression was inhibited in PTC tissue samples and PTC cell lines. There were statistically significant differences in expression of miR-663 with regard to age and tumor size. Upregulation of miR-663 suppressed PTC cell invasion and migration. Further study showed that transforming growth factor beta 1 (TGFβ1) was the direct target of miR-663 and mediated the effect of miR-663 on PTC development. By targeting TGFβ1, miR-663 efficiently regulates the expression of epithelial-mesenchymal transition (EMT) markers and matrix metalloproteinases (MMPs). The data indicated that miR-663 may suppress tumor invasion and migration by targeting TGFβ1 and regulate EMT progress of PTC cells.

Abstract
Human tumor necrosis factor receptor-associated protein 1 (Trap1) is a mitochondrial protein identical to heat shock protein 75 (HSP75) that plays an important role in protecting cells from oxidative stress and apoptosis. In this study, grass carp (Ctenopharyngodon idella) tumor necrosis factor receptor-associated protein 1 (designated as CiTrap1) was identified through two-dimensional electrophoresis (2-DE) analysis and its pattern of expression was investigated in grass carp kidney (CIK) cells infected with grass carp reovirus (GCRV). The full length cDNA of CiTrap1 contained an opening reading frame of 2157 bp that encoded a peptide of 718 amino acids. Phylogenetic analyses indicated that the CiTrap1 shared 87% identity with its homologue from zebrafish (Danio rerio). The transcriptional level of CiTrap1 in CIK cells was upregulated post virus infection as well as poly (I: C) stimulation. Following virus infection, grass carp PTEN-induced putative kinase 1 (PINK1) and Sorcin, whose coding proteins interact with Trap1 in human, were simultaneously upregulated with CiTrap1. Typical characteristics of apoptosis were observed in CIK cells infected with GCRV by DAPI staining, DNA ladder electrophoresis, TUNEL assay and Annexin Ⅴ labeling. RNAi-mediated silencing of CiTrap1 in CIK cells resulted in the increased rate of virus-induced apoptotic cells. The results of this study suggest that CiTrap1 is involved in the host's innate immune response to viral infection possibly through protecting infected cells from apoptosis.

Int J Mol Med 2015; 35:909-14.

Abstract
For a number of years, seaweed has been used as a functional food in Asian countries, particularly in Korea, Japan and China. Pyropia yezoensis is a marine red alga that has potentially beneficial biological activities. In this study, we examined the mechanisms through which a Pyropia yezoensis peptide [PYP1 (1–20)] induces the proliferation of IEC-6 cells, a rat intestinal epithelial cell line, and the involvement of the epidermal growth factor receptor (EGFR) signaling pathway. First, cell viability assay revealed that PYP1 (1–20) induced cell proliferation in a concentration-dependent manner. Subsequently, we examined the mechanisms responsible for this induction of proliferation induced by PYP1 (1–20). EGFR is widely expressed in mammalian epithelial tissues, and the binding of this ligand affects a variety of cell physiological parameters, such as cell growth and proliferation. PYP1 (1–20) increased the expression of EGFR, Shc, growth factor receptor-bound protein 2 (Grb2) and son of sevenless (SOS). EGFR also induced the activation of the Ras signaling pathway through Raf, MEK and extracellular signal-regulated kinase (ERK) phosphorylation. In addition, cell cycle analysis revealed the expression of cell cycle-related proteins. The results demonstrated an increased number of cells in the G1 phase and an enhanced cell proliferation. In addition, the upregulation of cyclin D, cyclin E, Cdk2, Cdk4 and Cdk6 was observed accompanied by a decreased in p21 and p27 expression. These findings suggest that PYP1 (1–20) stimulates the proliferation of rat IEC-6 cells by activating the EGFR signaling pathway. Therefore, PYP1 (1–20) may be a potential source for the development of bio-functional foods which promotes the proliferation of intestinal epithelial cells.

Abstract
Previously, we examined various apoptosis pathways in the AGS gastric cancer cell line using Capsosiphon fulvescens glycoprotein (Cf-GP). In this study, we focused on the downregulation of the Wnt-1 signaling pathway and cell cycle arrest. Upregulation of the Wnt signaling pathway has been observed in various cancer cells. The Wnt signal ligand acts in both canonical and non-canonical pathways. Among them, Wnt-1 was dependent on the canonical pathway. Here, we show inhibition of Wnt-1 signaling, β-catenin and transcription factors in AGS cells via Cf-GP. First, we examined the Frizzled receptor and Wnt-1 signal-related proteins including Axin, LRP, β-catenin, APC and GSK-3β. In addition, the expression levels of transcription factors Tcf/LEF were determined by western blot analysis and RT-PCR. Based on the data, we confirmed downregulation of the Wnt-1 signaling pathway by Cf-GP. Also, we determined the expression levels of cell cycle-related proteins cyclin D and c-myc, and looked for cell cycle arrest by cell cycle test analysis. We found that AGS cells arrested in the G0/G1 phase by Cf-GP. These results provide a mechanism of AGS cell inhibition through the downregulation of Wnt-1 signaling by Cf-GP.
