The latter two were transfected with&nbsp; mir-186 agent and antagonist, respectively. Cell viability, colony formation potential, cell cycle ratio, and Jagged-1 mRNA and protein&nbsp; levels were measured using various assays.<br><strong>Results</strong>: Cell growth increased over time in all groups. However, mir-186 overexpression cells showed significantly decreased growth and&nbsp; colony formation capacity, relative to control, while the mir-186 inhibition cells showed significantly higher growth and colony formation&nbsp; capacity. The study revealed a higher proportion of G0/G1 stage cells and lower proportion of S-phase cells in mir-186 overexpression cells than in control cells. The opposite effect was seen in mir-186 inhibition cells. Jagged-1 protein and mRNA levels were significantly&nbsp; lower in mir-186 overexpression cells and higher in mir-186 inhibition cells than in control group. The Jagged-1 knockout group showed&nbsp; significantly higher Jagged-1 mRNA and protein levels than both the control and mir-186 overexpression groups (p &lt; 0.05).<br><strong>Conclusion</strong>: When overexpressed, mir-186 inhibits the growth of multiple myeloma cells by inhibiting cell colony-formation capacity and&nbsp; by regulating cell cycle through mir-186-induced regulation of the expression of Jagged-1. there is need for more research to confirm the&nbsp; clinical benefits of therapies based on these findings.</p> Jinfeng Dong, Xiaoqiang Zheng Copyright (c) 2024 https://www.ajol.info/index.php/tjpr/article/view/264147 Mon, 05 Feb 2024 00:00:00 +0000 MiR-25 enhances the proliferation, invasion and migration of nasopharyngeal carcinoma cells through targeted regulation of RAGE expression https://www.ajol.info/index.php/tjpr/article/view/264150 <p><strong>Purpose</strong>: To determine the effect of microRNA-25 (miR-25) on the proliferation, invasion, and migration of nasopharyngeal carcinoma&nbsp; cells, and the involvement of targeted regulation of late glycation end product receptor (RAGE) in the process.<br><strong>Methods</strong>: Three groups of cells comprising; routinely cultured nasopharyngeal normal epithelial cell line NP69 without any treatment&nbsp; (blank control group), untreated human nasopharyngeal carcinoma cell line 5-8F, also cultured routinely (nasopharyngeal carcinoma&nbsp; group) and 5-8F human nasopharyngeal carcinoma cells infected with lentiviral vectors for miR-25 gene knockdown and cultured after&nbsp; stable transduction (miR-25 knockdown group). Cell proliferation was assessed using CCK-8 assay, while Western blot assay and&nbsp; quantitative polymerase chain reaction (qPCR) were used to measure protein and mRNA expression levels of relevant genes. Transwell&nbsp; assay was utilized to evaluate cell migration and invasion.<br><strong>Results</strong>: The miR-25 expression level was significantly increased in nasopharyngeal carcinoma group (p &lt; 0.05). Cell proliferation,&nbsp; migration, and invasion rates in miR-25 knockdown group were lower than those in nasopharyngeal carcinoma group (p &lt; 0.05).&nbsp; Apoptosis rate of cells and levels of apoptotic proteins were significantly elevated, whereas bcl-2 level was significantly reduced in miR-25&nbsp; knockdown group when compared to nasopharyngeal carcinoma group (p &lt; 0.05). Protein expression levels of RAGE and S100P was&nbsp; significantly increased in nasopharyngeal carcinoma group, but significantly down-regulated in miR-25 knockdown group (p &lt; 0.05).&nbsp; <strong>Conclusion</strong>: Expression of miR-25 increases in nasopharyngeal carcinoma cells. Suppression of miR25 results in decreased viability of&nbsp; nasopharyngeal carcinoma cells and inhibits cell proliferation, migration, and invasion, while enhancing apoptosis. The mechanism&nbsp; underlying these effects was associated with modulation of protein expressions of RAGE and S100P. Targeted regulation of late glycation&nbsp; end-product receptors hold promising potential as prospective biomarker for therapeutic interventions targeting specific cancers.</p> Yang Jing, Qingxia Zhao, Yujuan Wang, Pei Lin Copyright (c) 2024 https://www.ajol.info/index.php/tjpr/article/view/264150 Mon, 05 Feb 2024 00:00:00 +0000 Honokiol inhibits gallbladder cancer proliferation and epithelial mesenchymal transformation by suppressing TMPRSS4-induced PI3K/AKT activation https://www.ajol.info/index.php/tjpr/article/view/264154 <p><strong>Purpose</strong>: To determine the role of TMPRSS4 in gallbladder cancer (GBC).</p> <p><strong>Methods</strong>: Quantitative reverse-transcription-polymerase chain reaction (qRT-PCR) and western blotting were used to evaluate the&nbsp; expression of genes, while CCK-8 kit and foci formation assay were used to assess cell growth in GBC-SD and non-obliterative zone (NOZ)&nbsp; cell lines. Cell apoptosis was evaluated by flow cytometry, while cell migration and cell invasion were determined by Transwell assay in GBCSD and NOZ cell lines.</p> <p><strong>Results</strong>: TMPRSS4 was highly expressed in GBC cells, compared to normal cell, HIBEC. Overexpression of TMPRSS4 enhanced cell viability&nbsp; and 2D foci formation in GBC-SD (stratified) and NOZ; however, knockdown of TMPRSS4 reduced cell proliferation and colony formation&nbsp; in the cell lines (p &lt; 0.05). TMPRSS4 deficiency increased cell apoptosis but its reinforced expression decreased cell apoptosis in GBC cell&nbsp; lines (p &lt; 0.05). Moreover, TMPRSS4 positively regulated cell invasion and migration in GBC cells by upregulating TWIST1, vimentin and N- cadherin. TMPRSS4 also regulated the activation of PI3K/AKT signal pathway. Furthermore, honokiol inhibited gallbladder cancer&nbsp; proliferation and migration, and induced cell apoptosis by suppressing TMPRSS4-induced PI3K/AKT activation (p &lt; 0.05).</p> <p><strong>Conclusion:</strong>&nbsp; TMPRSS4 plays an important role in regulating cell growth, apoptosis and metastasis of gallbladder cancer cells (GBC). Thus, TMPRSS4&nbsp; might be a new biomarker in gallbladder cancer.&nbsp;&nbsp;</p> Conglin Lin, Congren Wang, Mingzhu Li, Zhibing Cai Copyright (c) 2024 https://www.ajol.info/index.php/tjpr/article/view/264154 Mon, 05 Feb 2024 00:00:00 +0000 Knockdown of TRIP13 inhibits gastric cancer stemness and cisplatin resistance by regulating FBXW7/ENO1 axis https://www.ajol.info/index.php/tjpr/article/view/264155 <p><strong>Purpose</strong>: To explore the role of thyroid hormone receptor interactor 13 (TRIP13) in gastric cancer (GC) and the associated mechanism.</p> <p><strong>Methods</strong>: TRIP13 expression in GC was found in The Cancer Genome Atlas (TCGA) database and siTRIP13 was transfected in GC cells in order to generate cell lines with low TRIP13 expression. Cell proliferation was determined by colony formation assay, while cell migration&nbsp; and invasion were evaluated by scratch test and Transwell assay, respectively. Sphere formation assay was used to assess cell stemness&nbsp; characteristics whereas half-inhibitory concentration (IC50) value was evaluated by Cell Counting Kit-8 (CCK8). F-box and WD repeat&nbsp; domain containing 7 (FBXW7) and enolase 1 (ENO1) expression were determined by western-blot assay.</p> <p><strong>Results</strong>: TRIP13 was significantly expressed in GC based on TCGA database (p &lt; 0.001) and high expression predicted poor prognosis in&nbsp; GC patients (p &lt; 0.05). Based on the findings of the cell function assay, si-TRIP13 inhibited the proliferation, migration, invasion and&nbsp; stemness of GC cells (p &lt; 0.001) and decreased the IC<sub>50</sub> value. Mechanically, knockdown of TRIP13 decreased ENO1 expression level by&nbsp; stabilizing FBXW7.</p> <p><strong>Conclusion</strong>: TRIP13 functions as an oncogene in GC and stimulates growth and stemness via FBXW7/ENO1 pathway in&nbsp; GC. Thus, a potential therapeutic target for the treatment of gastric cancer is provided by this study.</p> Jiayun Liu, Che Chen, Guannan Wu, Xuequan Yao, Fukun Liu, Shenlin Liu Copyright (c) 2024 https://www.ajol.info/index.php/tjpr/article/view/264155 Mon, 05 Feb 2024 00:00:00 +0000 MiR-128-3p inhibits the proliferation, migration and invasion of human nasopharyngeal carcinoma cells via EMT https://www.ajol.info/index.php/tjpr/article/view/264157 <p><strong>Purpose</strong>: To investigate the effect of overexpressing miR-128-3p on the migration, invasion, and proliferation of human nasopharyngeal&nbsp; cancer cells, and associated pathways.<br><strong>Methods</strong>: Cell counting kit-8 (CCK-8) and clone creation tests were used to investigate the effect of miR-128-3p inhibitor on the growth of&nbsp; C666-1 cells. The inhibitor control and miR-128-3p inhibitor were transfected into human nasopharyngeal cancer cells (C666-1) and&nbsp; allowed to incubate for 48 h. Cell migration and invasion assays were conducted using Transwell and Scratch assays. Cell cycle was assessed using propidium iodide (PI) single-staining method, while expression of miR-128-3p was evaluated by quantitative reverse&nbsp; transcription-polymerase chain reaction (qRT-PCR). Expression levels of vimentin, E-cadherin, and N-cadherin were determined by&nbsp; Western blot.<br><strong>Results</strong>: MiR-128-3p inhibitor transfection in C666-1 cells significantly increased cell proliferation, cell viability, and clonal proliferation,&nbsp; and also significantly reduced miR-128-3p expression levels, and enhanced cell migration and invasion. In C666-1 cells, inhibition of&nbsp; miR-128-3p induced epithelial mesenchymal transition (EMT).<br><strong>Conclusion</strong>: MiR-128-3p inhibits nasopharyngeal cancer cells from proliferating, migrating, and invading by regulating epithelial&nbsp;&nbsp; mesenchymal transition. MiR-128-3p may therefore be a viable therapeutic target for nasopharyngeal cancer. Future studies are&nbsp; required&nbsp; to yield pertinent data in support of this hypothesis.&nbsp;</p> Jingli Li, Hui Wang Copyright (c) 2024 https://www.ajol.info/index.php/tjpr/article/view/264157 Mon, 05 Feb 2024 00:00:00 +0000 Small molecule inhibitor azd1480 reverses radiotherapy resistance in NSCLC by targeting JAK2/STAT3 pathway https://www.ajol.info/index.php/tjpr/article/view/264161 <p><strong>Purpose</strong>: To investigate the effect of small molecule inhibitor AZD1480 on radiotherapy resistance in non-small cell lung cancer (NSCLC),&nbsp; and the involvement of Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway in the process.</p> <p><strong>Methods</strong>: Radiation-resistant cell lines A549-20F, A549-30F, A549-40F and H460, H46040F, H460- 40F, and H460-40F were established, and&nbsp; expressions of proteins related to JAK/STAT pathway, mitogen-activated protein (MAPK) pathway and transforming growth factor-β (TGF- β) were assayed. The JAK2V617FH460 overexpression cell line and JAK2H460 cell line were established, and expressions of ATGL and&nbsp; CPT1A were compared. The H460 cells and H460-40F cells were treated with JAK2 small molecule inhibitor AZD1480, and the expressions&nbsp; of ATGL, CPT1A and JAK2/STAT3 pathway-related proteins were compared. The survival and proliferation of cell lines were also compared.&nbsp;</p> <p><strong>Results</strong>: The JAK/STAT pathway was significantly enriched, and MAPK and TGF-β were up-regulated. In H460 cells, JAK2/STAT3&nbsp; route was obvious, suggesting that radiotherapy activated JAK2/STAT3 pathway in NSCLC cells. Significant down-regulations of p- JAK2Y1007, JAK2, p-STAT3s727, STAT3, ATGL and CPT1A proteins expressions were seen in H460 + AZD1480 group, relative to H460 group, but protein levels of p-JAK2Y1007, JAK2, p-STAT3s727, STAT3, ATGL and CPT1A were significantly lower in H460-40F + AZD1480 group than&nbsp; in H460-40F group (p &lt; 0.05). The survival and proliferation rates were significantly lower in A549 + AZD1480 group than in A549 and&nbsp; A549-40F groups (p &lt; 0.05).</p> <p><strong>Conclusion</strong>: Radiotherapy up-regulates the expressions of ATGL and CPT1A in NSCLC cells by activating the&nbsp; JAK2/STAT3 pathway, while AZD1480, a small molecule inhibitor, reverses the radiation resistance of NSCLC by targeting JAK2/STAT3&nbsp; pathway and key enzymes of lipid metabolism. Therefore, azd1480 may enhance clinical treatment efficacy in NSCLC patients by reducing&nbsp; radiation resistance.&nbsp;</p> Ying Mao, Yang Yao, Li Liu Copyright (c) 2024 https://www.ajol.info/index.php/tjpr/article/view/264161 Mon, 05 Feb 2024 00:00:00 +0000 Enhancement of the antitumor effect of cisplatin and ginsenoside Rg3 by encapsulation in polylactic-co-glycolic acid nanoparticles https://www.ajol.info/index.php/tjpr/article/view/264164 <p><strong>Purpose</strong>: To develop dual-loaded polylactic-co-glycolic acid (PLGA) nanoparticles (NPs) with two chemotherapeutic agents, i.e., cisplatin (DDP) and 20(R)-ginsenoside Rg3(Rg3), and to evaluate the drug release profiles and synergistic inhibitory effects of the nanoparticles on lung cancer A549 cells.<br><strong>Methods</strong>: The dual-laden PLGA NPs were synthesized using modified emulsion and solvent vaporization procedures. Drug loading (DL) and efficacy of co-encapsulation (EE) were determined with a modification of column elution technique. The cytotoxic and inhibitory effects of individual and combined drugs on A549 lung cancer cells were evaluated using MTT assay.<br><strong>Results</strong>: A sustained pattern of drug release was shown by PLGA/DDP, PLGA/Rg3, and PLGA/DDP+Rg3. The formulated PLGA and unbound drugs exerted dose- and time-reliant cytotoxic effects on A549 cells. At all concentrations tested, drugs encapsulated in PLGA nanoparticles were more effective in killing the cells than the free drugs (p &lt; 0.05). In particular, PLGA/DDP + Rg3 formulation produced a synergistic inhibitory effect on the proliferation of A549 cells.<br><strong>Conclusion</strong>: Single- and dual-load PLGA groups display variabilities in profiles of drug release and in vitro cytotoxic effect. Furthermore, dual-load PLGA group produces significantly enhanced treatment effect. These results suggest that PLGA formulations hold great potential for future drug delivery.</p> Wen Xu, Qingping Zhang, Leiming Sun Copyright (c) 2024 https://www.ajol.info/index.php/tjpr/article/view/264164 Mon, 05 Feb 2024 00:00:00 +0000 Catalpol attenuates EMT by inhibiting Wnt/β-catenin and TGF-β/Smads signaling to alleviate kidney fibrosis https://www.ajol.info/index.php/tjpr/article/view/264166 <p><strong>Purpose</strong>: To determine the anti-fibrosis effect and underlying mechanism of action of catalpol (CAT) in chronic kidney disease (CKD).</p> <p><strong>Methods</strong>: Forty (40) rats were randomly divided into a sham group (10 rats) and a unilateral ureteral obstruction (UUO) model group (30&nbsp; rats) which was further randomly subdivided into three groups of ten (10) rats each: the UUO model group, UUO + CAT low-dose group,&nbsp; and UUO + CAT high-dose group. HK-2 cells were stimulated with TGF-β1 for in vitro studies. Renal injury and fibrotic lesions were determined by H&amp;E and Masson’s staining. Key proteins of TGF-β/Smads and Wnt/β-catenin signaling pathways involved in epithelial- mesenchymal transition (EMT) were determined by immunohistochemistry, immunofluorescence staining and Western blotting.</p> <p><strong>Results</strong>: Catalpol downregulated the expression of α-SMA (p &lt; 0.05) and upregulated the expression of E-cadherin (p &lt; 0.05) stimulated&nbsp; by TGF-β1 and LiCl in HK-2 cells, which is consistent with the role of DKK1 in vitro. CAT ameliorated renal fibrosis and repressed the&nbsp; expression of key proteins of TGFβ/Smads and Wnt/β-catenin pathways in UUO rats.</p> <p><strong>Conclusion:</strong> Catalpol inhibits EMT and alleviates&nbsp; kidney fibrosis by suppressing the hyperactivation of TGF-β/Smad and Wnt/β-catenin signaling pathways. Therefore, CAT is a promising&nbsp; therapeutic drug for renal fibrosis.</p> Hong-yan Gao, Tao-ren Ruan, Mao Xing, Yi Chen, Shu-tong Bai, Jin-kun Liu, Xiao-wen Yu, Jing Feng, Xiao-yu Xu, Qin Wang Copyright (c) 2024 https://www.ajol.info/index.php/tjpr/article/view/264166 Mon, 05 Feb 2024 00:00:00 +0000 Anti-parkinsonian, anti-inflammatory, anti-microbial, analgesic, anti-hyperglycemic and anticancer activities of poly-fused ring pyrimidine derivatives https://www.ajol.info/index.php/tjpr/article/view/264168 <p><strong>Purpose</strong>: To investigate the anti-inflammatory, anti-cancer, anti-parkinsonian, anti-microbial, analgesic,&nbsp; and anti-hyperglycemic&nbsp; properties of a variety of poly-fused pyrimidine derivatives.</p> <p><strong>Methods</strong>: A novel series of fused pyrimidine derivatives 1-6 were synthesized by reacting amino&nbsp; pyrazole derivatives with active&nbsp; methylene derivatives to give the corresponding compounds 1-6.

(Asteraceae).</p> <p><strong>Methods</strong>: A bioassay-guided fractionation was used to isolate the active principle, luteolin, which structure was elucidated using <sup>1</sup>H and&nbsp;&nbsp; <sup>13</sup>C NMR. The cytotoxic effects of luteolin and doxorubicin (positive control) in the breast cancer cell lines MDA-MB-231 and MCF-7, and in normal fibroblasts, were determined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay.</p> <p><strong>Results</strong>: Luteolin was isolated from the ethyl acetate extract of the aerial parts of Anthemis palestina. With an IC<sub>50</sub> value of 14.91 ± 5.77&nbsp; µM for MDA-MB-231 cells, luteolin was less active than doxorubicin. However, with respect to MCF-7 cells, there was no significant&nbsp; difference in the cytotoxicity values of luteolin and doxorubicin, with IC<sub>50</sub> value of 29.28 ± 11.85 µM for luteolin. However, with an IC<sub>50</sub>&nbsp; value of 51.39 ± 18.51 µM against fibroblasts, luteolin was significantly safer than doxorubicin.</p> <p><strong>Conclusion</strong>: Luteolin might be responsible&nbsp; for the cytotoxicity of Anthemis palestina. The high level of luteolin cytotoxicity indicates the potential benefits of <em>Anthemis palestina</em>, not&nbsp; only in terms of its taste, but also for its likely positive therapeutic impact on cancer, especially breast cancer.&nbsp;</p> Yahia Z.

Spreng exerts antioxidant and anti-neuroinflammatory properties in LPS-stimulated BV2 microglia https://www.ajol.info/index.php/tjpr/article/view/264178 <p><strong>Purpose</strong>: To evaluate the antioxidant and anti-neuroinflammatory properties of the leaves, seeds and pulp of Momordica cochinchinensis&nbsp; Spreng (commonly known as Gac) in vitro and in lipopolysaccharide (LPS)-activated BV2 microglial cells.</p> <p><strong>Methods</strong>: Lipopolysaccharide was applied to BV2 cells for 24 h in the presence or absence of Gac extracts. Then, levels of reactive oxygen&nbsp; species (ROS) were assayed using CM-H2DCFDA method, while nitric oxide (NO) level was determined with Griess reagent. The levels of&nbsp; TNF-α and IL-6 were&nbsp; determined using ELISA. Three different assays were used for determination of in vitro antioxidant activities of the&nbsp; extracts, namely, 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging; 2,2’-azinobis-3- ethylbenzthiazoline-6-sulfonic acid (ABTS) scavenging,&nbsp; and ferric-reducing antioxidant power (FRAP). Total flavonoids content (TFC) and total phenolic content (TPC) were also determined.&nbsp;</p> <p><strong>Results</strong>: There were significantly higher levels of ROS, NO, TNF and IL-6 in LPS-treated BV2 cells than in control cells (p &lt; 0.05). However,&nbsp; exposure of LPS treated BV2 cells to the leaf, seed and pulp extracts of Gac led to marked decreases in levels of ROS and inflammatory&nbsp; mediators, when compared with untreated cells, with the seed extract producing significantly larger decreases in levels of ROS and inflammatory mediators than the leaf and pulp extracts (p &lt; 0.05). The DPPH and ABTS radical scavenging activities and total reducing&nbsp; power activities of the seed extract were superior to those of the leaf and pulp extracts. Moreover, the seed extract showed higher&nbsp; contents of TFC and TPC than the other two extracts.</p> <p><strong>Conclusion</strong>: Gac extracts exert antioxidant and anti-neuroinflammatory effects on LPS-activated BV2 cells and in an in vitro model.&nbsp; Therefore, Gac extracts, especially seed extract, may be beneficial in the preparation of innovative antioxidative and anti-neuroinflammatory herbal remedies, as well as dietary supplements.&nbsp;</p> Nootchanat Mairuae, Benjaporn Buranrat, Poonlarp Cheepsunthorn Copyright (c) 2024 https://www.ajol.info/index.php/tjpr/article/view/264178 Mon, 05 Feb 2024 00:00:00 +0000 Random Amplified Polymorphic DNA (RAPD)-PCR analysis of genotypic and phenotypic characteristics of MethicillinResistant <i>Staphylococcus epidermidis</i> (MRSE) strains involved in biofilm formation https://www.ajol.info/index.php/tjpr/article/view/264179 <p><strong>Purpose</strong>: The current study aims to investigate genotypic and phenotypic aspects of methicillinresistant Staphylococcus epidermidis (MRSE) strains involved in the biofilm formation and the attendance of the icaADB gene and genotypic characterization of this gene by random amplified polymorphic DNA (RAPD) PCR.<br><strong>Methods</strong>: 60 Staphylococcus epidermidis strains were isolated from clinical specimens, suspected of having the bacteria, from the laboratories of Isfahan. Biofilm formation was measured by the microtiter plate method. The attendance of biofilm formation genes was studied using PCR and all isolates producing biofilm (strong and moderate) were genetically classified by RAPD-PCR.<br><strong>Results</strong>: 37 isolates (61.7%) were MRSE and all positive biofilm strains. The prevalence of biofilmrelated genes in the isolates was SesC (100%), SesI (45.9%), icaA (29.7%), icaB (37.8%), icaC (81.08%), icaD (70.2%), arcA (81.08%), and opp3AB (70%). PCR analysis showed that among 30 isolates of strong and medium biofilm production, 70% (21/30) positive for the icaADB gene.

Advanced drug delivery systems like implants, nano or microparticles,&nbsp; punctal plugs, contact lenses, topical ring-type systems, gels, and other depot systems such as intracameral, supraciliary, and intravitreal&nbsp; applied in the extraocular, periocular, or intraocular sites, significantly enhance medication absorption, reduce adverse effects, and&nbsp; improve patient compliance. Poor treatment adherence, stemming from various reasons, lead to inadequate glaucoma management,&nbsp; increasing direct (34 to 45 %) and indirect costs (55 to 66 %) of therapy. As a result, a variety of treatments including enhanced drug&nbsp; delivery systems have been tested to address these concerns, and some modern pharmaceuticals and drug delivery technologies are&nbsp; being developed.&nbsp;</p> Farhan Alshammari Copyright (c) 2024 https://www.ajol.info/index.php/tjpr/article/view/264197 Mon, 05 Feb 2024 00:00:00 +0000 Effect, main targets and molecular mechanisms of glycyrrhiza-derived flavonoids on malignant tumor in comprehensive cancer treatment https://www.ajol.info/index.php/tjpr/article/view/264198 <p><em>Glycyrrhiza flavonoids</em> (GF) are essential antitumor components of <em>Glycyrrhiza uralensis, Glycyrrhiza </em><em>glabra, </em>and<em> Glycyrrhiza inflata</em> roots and&nbsp; tubers, with antioxidant, anti-inflammatory, antibacterial, immune-enhancing amongst other properties. In recent years, significant&nbsp; progress has been made in understanding the mechanisms and targets of GF in various pharmacological settings. This review summarizes the clinical value, targets and research progress of the molecular mechanisms underlying GF in the treatment of malignant&nbsp; tumors. This will provide as a theoretical foundation for further studies into GF as a therapeutic option in the management of cancerous&nbsp; tumors.</p> Wei Hu, Wenzhe Ma, Bo Li, Yu Hou, Rongyang Dai Copyright (c) 2024 https://www.ajol.info/index.php/tjpr/article/view/264198 Mon, 05 Feb 2024 00:00:00 +0000
