Aloesin is an active constituent of the herb aloe vera and plays a crucial role in anti-inflammatory activity, ultraviolet protection, and antibacterium. We investigated the role and possible mechanisms of aloesin in the cell growth and metastasis of ovarian cancer. It was found that aloesin inhibited cell viability and cell clonality in a dose-dependent manner. It arrests the cell cycle at the S-phase and induced apoptosis in SKOV3 cells. In an in vivo experiment, it was observed that aloesin inhibited tumor growth. Moreover, it inhibited migration and invasion of cancer in SKOV3 cells. Interestingly, members from the mitogen-activated protein kinase (MAPK) signaling family became less phosphorylated as the aloesin dose increased. This suggests that aloesin exerts its anticancer effect through the MAPK signaling pathway. Our data also highlights the possibility of using aloesin as a novel therapeutic drug for ovarian cancer treatment.

Abstract Background: The present study explored the possible functions and the underlying mechanism of long Non-coding RNA LINC02085 in rheumatoid arthritis (RA). Methods: Primary fibroblast-like synoviocytes (FLS) were separated from synovial tissues and was established cell lines, then cultured for subsequent cell experiments by transfecting different vectors. Rat with AA were injected with sh-LINC02085. The progression of AA was explored by measuring arthritis score and histologic analysis. ELISA analysis was employed to detect the levels of inflammatory cytokines. CCK8 assay, migration and invasion assays were used to evaluate the proliferation, migration and invasion abilities of cells, respectively. Besides, the levels of the the PI3K/AKT pathway-related proteins were measured by WB and IF. Results: The expression level of LINC02085 was significant high in patients with RA, and positively associated with clinical indexes. We found that LINC02085 was upregulated in RA -FLS and TNF-αstimulated. And overexpression of LINC02085 could promote proliferation, migration and invasion induced by TNF-α, through upregulating the levels of TNF-αand TNFAIP2 and promoting the activation of PI3K/AKT pathway. Whereas downexpression of LINC02085 received the opposite results. Knockdown of LINC02085 significantly ameliorated the progression of AA reflected by decreased arthritis score and cartilage destruction. Conclusion: The present study revealed that LINC02085 could regulate cell growth and inflammatory response of RA-FLS by activating the PI3K/ AKT signaling pathway, subsequently playing important roles in promoting the occurrence and development of RA.

Underlying Mechanisms

Transfer RNA-derived RNA fragments (tRFs) belong to non-coding RNAs (ncRNAs) discovered in most carcinomas. Although some articles have demonstrated the characteristics of tRFs in gastric carcinoma (GC), the underlying mechanisms still need to be elucidated. Meanwhile, it was reported that the MAPK pathway was momentous in GC progression. Thus we focused on investigating whether tRF-Glu-TTC-027 could act as a key role in the progression of GC with the regulation of the MAPK pathway. We collected the data of the tRNA-derived fragments expression profile from six paired clinical GC tissues and corresponding adjacent normal samples in this study. Then we screened tRF-Glu-TTC-027 for analysis by using RT-PCR. We transfected GC cell lines with tRF-Glu-TTC-027 mimics or mimics control. Then the proliferation, migration, and invasion assays were performed to assess the influence of tRF-Glu-TTC-027 on GC cell lines. Fluorescence in situ hybridization assay was conducted to confirm the cell distribution of tRF-Glu-TTC-027. We confirmed the mechanism that tRF-Glu-TTC-027 influenced the MAPK signaling pathway and observed a strong downregulation of tRF-Glu-TTC-027 in clinical GC samples. Overexpression of tRF-Glu-TTC-027 suppressed the malignant activities of GC in vitro and in vivo. MAPK signaling pathway was confirmed to be a target pathway of tRF-Glu-TTC-027 in GC by western blot. This is the first study to show that tRF-Glu-TTC-027 was a new tumor-suppressor and could be a potential object for molecular targeted therapy in GC.

Abstract Background: Esophageal cancer (ESCC) is one of the most common malignant tumors in the digestive system. This study aims to explore the effects of sperm associated antigen 5 (SPAG5) on cell growth, metastasis, and azithromycin resistance in esophagus cancer and its molecular mechanism.Methods: The DEGs were obtained from GSE92396, GSE17351, and GSE9982 datasets about ESCC. The PPI network was constructed using the STRING database and was visualized using Cytoscape software. The cytohubba plug-in of Cytoscape software was used to identify the hub genes of the PPI network. The DEGs were used to perform GO and KEGG pathway enrichment analysis using the DAVID database. Statistical analysis was performed to test the clinical and prognostic significance of SPAG5. Cell viability, proliferation, apoptosis, migration, and invasion were detected using CCK-8, colony formation, flow cytometry, transwell and scratch-wound assays. The expression of related genes was detected by qRT-PCR, western blot and IHC assays. The oncogenicity of SPAG5 in ESCC cells was determined using the nude mouse transplantation tumor experiment.Results: Ninety-three overlapping genes from the DEGs were used to construct the PPI network, and mainly enriched in BP, CC, and MF terms. COX regression analysis of OS showed that SPAG5 expression and pN category were correlated with OS. Univariate and multivariate analyses showed that SPAG5 was an independent prognostic factor for OS in ESCC. The ROC curve analysis showed the AUC of SPAG5 was 0.74. Multiple logistic regression showed that SPAG5 were subsequently identified as an independent risk factor associated with OS. SPAG5 overexpression was detected in ESCC tissues and cell lines, and improved cell proliferation. SPAG5 knockdown reduced cell growth and metastasis and promoted its apoptosis. The functions of SPAG5 overexpression promoting ESCC cell growth and affecting cleaved caspase-3, Ki67, VEGF, and MMP-2/-9 expression were reversed by PI3K/AKT inhibitor. SPAG5 overexpression enhanced resistance to ADM in EC9706 and Eca109 cells and it was closely related to the activation of PI3K/AKT signaling pathway.Conclusion: The overexpression of SPAG5 was an independent good prognostic factor and promoted the proliferation, invasion, migration, and ADM resistance, and inhibited the apoptosis via activating PI3K/AKT signaling pathway in ESCC.

Abstract Background There is an urgent need to identify potential targets in anticancer therapy to improve the survival and prognosis of patients with ovarian cancer (OC). Herein, we investigated the functional significance of chemokine (C-X-C motif) ligand 14 (CXCL14) in OC cell growth and epithelial–mesenchymal transition (EMT). Methods qRT PCR and western blotting was used to detect CXCL14 mRNA level and protein expression, respectively. The functional mechanism of CXCL14 in OC was investigated by CCK-8, colony formation and transwell assays. The migration ability of OC cell was determined using wound healing. The protein expressions of CXCL14 and β-catenin in OC tissues were determined by immumohistochemical staining. Results We demonstrated that high levels of CXCL14 were associated with a worse prognosis in patients with OC. CXCL14 knockdown considerably restrained the growth, migration and invasion of OC cell in vitro. In contrast, ectopic CXCL14 overexpression yielded the opposite results. Investigations to determine the underlying molecular mechanisms revealed that the Wnt/β-catenin signaling pathway is involved in CXCL14-facilitated OC cell invasiveness. Conclusion These data collectively demonstrate that CXCL14 contributes to OC cell growth and metastatic potential by regulating the Wnt/β-catenin signaling pathway.

Abstract Background: Rhein is a natural agent isolated from the traditional Chinese medicine rhubarb, which has been used as a medicine in China since ancient times. Although rhein was found to have significant anticancer effects in different cancer models, the effect and the underlying mechanisms of action of rhein in colorectal cancer (CRC) remain unclear. The mTOR/p70S6 kinase (p70S6K) pathway has been demonstrated as an attractive target for developing novel cancer therapeutics.Methods: The human CRC cell lines HCT116, HCT15, and DLD1 and xenograft mice were used in this study to investigate the effects of rhein. Assessments of cellular morphology, cell proliferation, and anchorage-independent colony formation were performed to examine the effects of rhein on cell growth. Wound healing assay and transwell migration and invasion assay were conducted to detect cell migration and invasion. Cell cycle and apoptosis were investigated by flow cytometry and verified by immunoblotting. Tissue microarray was used to detect mTOR expression in patients with CRC. Gene overexpression and knockdown were implemented to analyze the function of mTOR in CRC. The in vivo effect of rhein was assessed in a xenograft mouse model.Results: Rhein significantly inhibited CRC cell growth by inducing S phase cell cycle arrest and apoptosis. It also inhibited CRC cell migration and invasion ability through EMT process. mTOR was highly expression in CRC cancer tissues and cells exhibited high mTOR expression. Overexpression of mTOR promoted cell growth, migration, and invasion ability, whereas mTOR knockdown diminished these phenomena of CRC cells in vitro. Moreover, rhein directly targeted mTOR and suppressed the mTOR/p70S6K signaling pathway in CRC cells. Intraperitoneal administration of rhein inhibited CRC cell HCT116 xenograft tumor growth through the mTOR/p70S6K pathway.Conclusions: Rhein exerted anticancer activity in vitro and in vivo through directly targeting mTOR and inhibiting mTOR/p70S6K signaling pathway. These data indicate that rhein is a potent anticancer agent that could be useful for the prevention or treatment of CRC.
