Abstract Background Hepatitis B virus (HBV) infection is a high-risk factor of hepatocellular carcinoma (HCC). Cellular immune responses are essential for HCC development, and the CD4+ and CD8+ T subtypes are identified as the primary anti-tumor immune cells. In the study, we investigated the effect and mechanism of amygdalin in the cellular immune response in HBV-related HCC and HCC progression. Methods The cell proliferation was examined by MTT analysis. Cells metastasis ability was detected by Invasion and migration assays. Quantification of apoptotic cells was performed with Flow cytometer assay. The protein levels of p-STAT3, STAT3, p-JAK2, JAK2, caspase-3, cleaved caspase-3 were detected by performing immunoblotting assays. Results We demonstrate that amygdalin treatment could rescue the HBV-T cell viability and IFN-γ and TNF-αproduction. In HBV-T cells, the MFI levels of CD8+ are lower than that in NC-T cells. Moreover, the phosphorylation levels of STAT3 and JAK2 are higher in HBV-T cells, compared to those in NC-T cells, and then reduced by amygdalin treatment. Co-culture with HBV-T cells could reduce IFN-γ and TNF-α, production while increase IL-6 and IL-10 production in HepG2.2.15 cells; these alterations could be partially reversed by amygdalin pretreatment. Finally, co-culture with HBV-T cells significantly promoted the cell viability, inhibited the apoptosis, and promoted the migration of HepG2.2.15 cells, and these alterations could be partially reversed by amygdalin treatment. Conclusion Our findings provide a rationale for further studies on the functions and mechanism of amygdalin inhibiting HBV-related HCC cell proliferation, invasion, and migration via T cell-mediated tumor immunity.

Abstract Background Overexpression of fibroblast growth factor receptor 3 (FGFR3) has been linked to tumor progression in many types of cancer. The role of FGFR3 in melanoma remains unclear. In this study, we aimed to uncover the role of FGFR3 in the growth and metastasis of melanoma. Methods FGFR3 knockdown and overexpression strategies were employed to investigate the effects of FGFR3 on colony formation, cell apoptosis, proliferation, migration, and in vitro invasion, along with the growth and metastasis of melanoma in a xenografts mouse model. The protein expression levels of extracellular signal-regulated kinase (ERK), protein kinase B (AKT), epidermal growth factor receptor (EGFR), and epithelial-mesenchymal transition (EMT) markers were determined by Western blot analysis. Results The mRNA expression of FGFR3 was higher in melanoma tissues than normal healthy tissues. FGFR3 expression in cutaneous malignant melanoma (CMM) tissues was positively correlated with the Breslow thickness and lymph node metastasis. In A357 cells, knockdown of the FGFR3 gene decreased the colony formation ability, cell proliferation, invasion, and migration, but increased the caspase 3 activity and the apoptosis rate; overexpression of FGFR3 increased the colony formation ability, cell proliferation, invasion, and migration, but decreased the caspase 3 activity and apoptosis rates. FGFR3 knockdown also upregulated E-cadherin, downregulated N-cadherin and vimentin, and decreased the phosphorylation levels of ERK, AKT, and EGFR. In the MCC xenografts mice, knockdown of FGFR3 decreased tumor growth and metastasis. Conclusions FGFR3, which is highly expressed in CMM tissues, is correlated with increased Breslow thickness and lymph node metastasis. FGFR3 promotes melanoma growth, metastasis, and EMT behaviors, likely by affecting the phosphorylation levels of ERK, AKT, and EGFR.

Preeclampsia (PE) is an idiopathic hypertension syndrome occurring after 20 weeks of gestation. Reports showed that lncRNAs expression was abnormal in preeclampsia. We aimed to investigate the role of lncRNA CEACAMP8 in the proliferation, invasion and migration of trophoblast cells to improve the preeclampsia. The cell transfection effects were determined by RT-qPCR analysis. The proliferation, invasion and migration of HTR-8/SVneo cells were detected by CCK-8 assay, transwell assay and wound healing assay. The flow cytometry analysis analyzed the cell cycle. Moreover, the expression of CDK2, cyclinD1, P21, MMP2, MMP9, E-cadherin, b-catenin and vimentin was determined by the western blot analysis. Consequently, CEACAMP8 inhibition promoted the proliferation, invasion and migration of HTR-8/SVneo cells and kept most of the cells in the S phase. The expression of proteins related to the proliferation, invasion and migration of HTR-8/SVneo cells were also changed in accordance with the increase of proliferation, invasion and migration of HTR-8/SVneo cells. In addition, lncRNA CEACAMP8 inhibition decreased the expression of E-cadherin and b-catenin, and increased the vimentin expression to promote the epithelial-mesenchymal transition. And, CEACAMP8 overexpression could reverse the above changes. This study indicated that CEACAMP8 inhibition promoted the proliferation, invasion and migration of HTR-8/SVneo cells and lncRNA CEACAMP8 overexpression reversed.

Purpose: To investigate the effects of chlorophenyl-benzoxime (CPBZX) on pancreatic cancer (PC) cell proliferation, invasion and migration, and the underlying mechanism of action. Methods: Pancreatic carcinoma cell lines (HuP-T4, HuP-T3 and BxPC-3) were cultured in Dulbecco's Modified Eagle medium (DMEM) containing 10 % fetal bovine serum (FBS), penicillin (100 U/mL) and streptomycin (10 μg/mL) at 37 ˚C in a humidified atmosphere containing 5 % CO2 and 95 % air. Cell proliferation was assessed using MTT assay. Real-time quantitative polymerase chain reaction (qRTPCR) and Western blotting were employed for the determination of changes in the levels of expression of carcinoembryonic antigen (CEA), interleukin-8 (IL-8) and cyclooxygenase-2 (COX 2). Cell invasion and migration were determined using Transwell and wound healing assays, respectively. Results: The results of MTT assay showed that CPBZX significantly and dose-dependently inhibited the proliferation of PC cells (p < 0.05). Incubation of HuP-T4 cells with CPBZX significantly and dosedependently reduced the invasive ability of the cells (p < 0.05). The migratory ability of HuP-T4 cells was also significantly and dose-dependently inhibited by CPBZX (p < 0.05). The results of Western blotting and qRT PCR showed that CPBZX treatment significantly and dose-dependently upregulated CEA mRNA expression (p < 0.05). On the other hand, the expressions of IL-8 and COX-2 were significantly and dose-dependently down-regulated by CPBZX. Treatment of pancreatic tumor mice with CPBZX significantly decreased tumor growth and metastasis of tumor cells to the pulmonary tissues, liver and lymph nodes (p < 0.05). Conclusion: The results of this study suggest that CPBZX inhibits the development and metastasis of PC via the down-regulation of IL-8 and COX 2 expressions, and therefore may find application in pancreatic cancer therapy.

Abstract Background and purpose: The anti-tumor effect of carnosol has been revealed in cancers. This research intends to explore the role and underlying mechanisms of carnosol in the skin cancer in vitro. Methods: Online database GEPIA was used to preliminarily analyze MMP11 expression in skin cancer and further performed overall survival evaluation based on TCGA data. 0, 5µM, 10 µM, 20 µM carnosol was added into the skin cancer A431 cell culture. Later, RT-PCR method detected the mRNA expression of MMP-11 and Elisa kits measured the concentrations of MMP11, phosphor-EGFR and total EGFR proteins as well as the biomarkers related to proliferation (Ki67) and EMT (E-cadherin and Vimentin) as well as Casepase-3. The 20µM carnosol group was selected to further study the regulatory effect of MMP11 in A431 cells.Colony formation examined the cell proliferation. Flow cytometry method checked cell apoptosis while Transwell method explored the cell invasion and migration. Results: MMP11 is upregulated in skin cancer and lower level of MMP11 or EGFR expression is correlated with higher overall survival rates. Carnosol addition inhibited the mRNA expression of MMP11 and lowered the protein concentrations of MMP11 and phosphor-EGFR. In addition, Ki67 and Vimentin concentration was inhibited by carnosol while E-cadherin was instead promoted. Caspase-3 activity was enhanced by carnosol. Upregulation of MMP11 recovered EGFR activation, cell proliferation and invasion while inhibited apoptosis, partly counteracted the function of carnosol in cells. Conclusion: Carnosol might induce cell apoptosis and inhibits invasion and proliferation in skin epidermoid cancer in vitro through MMP11-EGFR pathway.

Colon cancer is a common malignancy of the digestive tract, mostly occurring at the junction of the rectum and colon. It easily invades multiple internal organs and tissues, causing systemic injury and mortality to patients. The occurrence and development of colon cancer involve multiple genes and multiple factors. It is greatly significant to identify oncogenes and tumor suppressor genes that influence the development of colon cancer and to study their mechanism of action for colon cancer diagnosis and treatment. Furthermore, circRNA are involved in the development of several types of tumors by affecting miRNA regulation on target gene expression. In the present study, circ_0005075 siRNA and circ_0005075 siRNA + mir-335 inhibitor were transfected into colon cancer SW620 cells, and circ_0005075 gene expression was significantly decreased after transfecting circ_0005075 siRNA into SW620 cells. Silencing circ_0005075 expression significantly inhibited SW620 cell proliferation, invasion, and migration, and promoted apoptosis, downregulated PCNA and vimentin expression, and upregulated E-cadherin and cleaved caspase3 expression. After circ_0005075 siRNA + mir-335 was transfected, it inhibited circ_0005075 and mir-335 expression, which significantly affected the vigor, invasion and migration ability, apoptosis rate of SW620 cells, as well as PCNA, E-cadherin, vimentin, and cleaved caspase3 expression. Therefore, the present study demonstrated that circ_0005075 silencing inhibited the proliferation, invasion, and migration of SW620 cells and promoted apoptosis by upregulating mir-335 expression.
