The E3 ubiquitin ligase NEDD4 mediates cell migration signaling of EGFR in lung cancer cells.

EGFR-dependent cell migration plays an important role in lung cancer progression. Our previous study observed that the HECT E3 ubiquitin ligase NEDD4 is significantly correlated with tumor metastasis and required for migration and invasion signaling of EGFR in gastric cancer cells. However, how NEDD4 promotes the EGFR-dependent lung cancer cell migration is unknown. This study is to elucidate the mechanism by which NEDD4 mediates the EGFR lung cancer migration signaling.

The Level ofexpression determines the response of colon cancer cells to mitogen-activated protein kinases inhibitors.

Currently, it has been proposed that combination of 5-fluorouracil (5FU) with inhibitors of the mitogen-activated protein kinases (MAPKs) signaling pathway might enhance the efficacy of 5FU-based chemotherapy in colon cancer. Our study aimed to investigate an impact of TWIST1 silencing on the sensitivity of cancer cells to 5FU and selected MAPK inhibitors.

Human Papillomavirus 16 E6 Induces FoxM1B in Oral Keratinocytes through GRHL2.

High-risk human papillomavirus (HPV) is a major risk factor for oral and pharyngeal cancers (OPCs), yet the detailed mechanisms by which HPV promotes OPCs are not understood. Forkhead box M1B (FoxM1B) is an oncogene essential for cell cycle progression and tumorigenesis, and it is aberrantly overexpressed in many tumors. We previously showed that FoxM1B was the putative target of an epithelial-specific transcription factor, Grainyhead-like 2 (GRHL2). In the current study, we demonstrate that HPV type 16 (HPV-16) E6 induces FoxM1B in human oral keratinocytes (HOKs) and tonsillar epithelial cells (TECs) in part through GRHL2. FoxM1B was barely detectable in cultured normal human oral keratinocytes (NHOKs) and progressively increased in immortalized HOKs harboring HPV-16 genome (HOK-16B) and tumorigenic HOK-16B/BaP-T cells. Retroviral expression of HPV-16 E6 and/or E7 in NHOKs, TECs, and hypopharyngeal carcinoma cells (FaDu) revealed induction of FoxM1B and GRHL2 by the E6 protein but not E7. Both GRHL2 and FoxM1B were strongly induced in the epidermis of HPV-16 E6 transgenic mice and HPVoral squamous cell carcinomas. Ectopic expression of FoxM1B led to acquisition of transformed phenotype in HOK-16B cells. Loss of FoxM1B by lentiviral short hairpin RNA vector or chemical inhibitor led to elimination of tumorigenic characteristics of HOK-16B/BaP-T cells. Luciferase reporter assay revealed that GRHL2 directly bound and regulated the FoxM1B gene promoter activity. Using epithelial-specific Grhl2 conditional knockout mice, we exposed wild-type (WT) and Grhl2 KO mice to 4-nitroquinolin 1-oxide (4-NQO), which led to induction of FoxM1B in the tongue tissues and rampant oral tumor development in the WT mice. However, 4-NQO exposure failed to induce tongue tumors or induction of FoxM1B expression in Grhl2 KO mice. Collectively, these results indicate that HPV-16 induces FoxM1B in part through GRHL2 transcriptional activity and that elevated FoxM1B level is required for oropharyngeal cancer development.

Homeobox protein MSX1 inhibits the growth and metastasis of breast cancer cells and is frequently silenced by promoter methylation.

Deregulation of msh homeobox 1 (MSX1) has been identified to be associated with multiple human malignant neoplasms. However, the association of the expression and biological function of MSX1 with breast tumorigenesis, and the underlying mechanism remain largely unknown. Therefore, the present study examined the expression and promoter methylation of MSX1 in breast tumor cell lines, primary breast tumors and normal breast tissues using semi-quantitative, quantitative and methylation-specific reverse transcription‑polymerase chain reaction. Colony formation assays, flow cytometric analysis, and wound healing and Transwell assays were used to assess various functions of MSX1. Western blot analyses were also conducted to explore the mechanism of MSX1. The results revealed that MSX1 was broadly expressed in normal human tissues, including breast tissues, but was frequently downregulated or silenced in breast cancer cell lines and primary tumors by promoter methylation. Methylation of the MSX1 promoter was observed in 7/9 (77.8%) breast cancer cell lines and 47/99 (47.5%) primary tumors, but not in normal breast tissues or surgical margin tissues, suggesting that tumor-specific methylation of MSX1 occurs in breast cancer. Pharmacological demethylation reduced MSX1 promoter methylation levels and restored the expression of MSX1. The ectopic expression of MSX1, induced by transfection with a lentiviral vector, significantly inhibited the clonogenicity, proliferation, migration and invasion of breast tumor cells by inducing G1/S cell cycle arrest and apoptosis. Ectopic MSX1 expression also inhibited the expression of active β-catenin and its downstream targets c-Myc and cyclin D1, and also increased the cleavage of caspase-3 and poly (ADP-ribose) polymerase. In conclusion, MSX1 exerts tumor-suppressive functions by inducing G1/S cell cycle arrest and apoptosis in breast tumorigenesis. Its methylation may be used as an epigenetic biomarker for the early detection and diagnosis of breast cancer.

STAT3 promotes the proliferation and migration of hepatocellular carcinoma cells by regulating AKT2.

The aim of the present study was to investigate the correlation of STAT3 and AKT in HCC cells. HCC cells were transfected with si-STAT3 and si-AKT2and the mRNA expression of STAT3 and AKT was detected by RT-PCR, and the protein expression was measured by western blot. MTT assays were used to evaluate cell proliferation, and Transwell assays were performed to detect the ability of migration and invasion. The relationship between STAT3 and AKT was analyzed by ChIP and Dual-luciferase reporter (DLR) assays. A nude mice experiment was used to verify the correlation. In the present study, we found that the expression of p-AKT2 and its downstream molecules were reduced in HCC cells transfected with si-STAT3, and the expression of p-STAT3 and its downstream molecules was decreased in HCC cells transfected with si-AKT2. Moreover, the ability of HCC cells proliferation, migration and invasion was decreased in si-STAT3 transfection group, but AKT2 reversed the role of si-STAT3 in HCC cells. The ChIP experiment found that STAT3 could bind to the AKT2 promoter in HCC cells. The DLR assay showed that the luciferase activity of AKT2 promoter was enhanced in HCC cells treated by IL-6. The nude mice experiment found that the tumor grew slowly after transfection with the STAT3-siRNA lentiviral vector, while AKT2 reversed the effect. STAT3 and AKT2 had mutual regulatory relationship, and STAT3 promoted the occurrence and development of HCC by regulating AKT2.

Inhibition of enhancer of zeste homolog 2 increases the expression of p16 and suppresses the proliferation and migration of ovarian carcinoma cellsand.

Enhancer of zeste homolog 2 (EZH2) is a histone methyltransferase, which targets histone H3 lysine 27. Studies have reported that EZH2 is involved in the development of several types of tumor, including ovarian cancer. p16, a well-known cell cycle regulator, has been demonstrated to be a tumor suppressor gene in a variety of malignant cells. However, the regulatory association between EZH2 and p16 in ovarian cancer remains to be fully elucidated. The present study aimed to determine whether EZH2 is involved in the development of ovarian cancer by regulating the expression of p16. An EZH2 short hairpin RNA (shRNA) lentiviral vector was constructed and used for transducing A2780 and SKOV3 ovarian cancer cell lines. The expression levels of EZH2 and p16 in the ovarian cancer cells were detected using a reverse transcription-quantitative polymerase chain reaction and western blot analyses, respectively. The function of the inhibition of EZH2 in cell proliferation and migration were determined using a CCK-8 assay and Transwell assay. In addition, a nude mouse xenograft model was used to determine the function of EZH2 and p16 in the formation of ovarian cancer. The results revealed that the inhibition of EZH2 increased the expression of p16, and suppressed the proliferation and migration capabilities of ovarian cancer. The downregulated expression of EZH2 suppressed ovarian tumor formation. The results of the study revealed that p16 was negatively regulated by EZH2 in ovarian cancer, and that p16 and EZH2 are important in the tumorigenesis of ovarian cancer. EZH2 and p16 represent potential biomarkers for the diagnosis of ovarian cancer and as targets for ovarian cancer gene therapy.

Overexpression of heart-type fatty acid binding protein enhances fatty acid-induced podocyte injury.

Deregulated lipid metabolism is a characteristic of metabolic diseases including type 2 diabetes and obesity, and likely contributes to podocyte injury and end-stage kidney disease. Heart-type fatty acid binding protein (H-FABP) was reported to be associated with lipid metabolism. The present study investigated whether H-FABP contributes to podocyte homeostasis. Podocytes were transfected by lentiviral vector to construct a cell line which stably overexpressed H-FABP. Small interfering RNA capable of effectively silencing H-FABP was introduced into podocytes to construct a cell line with H-FABP knockdown. Certain groups were treated with palmitic acid (PA) and the fat metabolism, as well as inflammatory and oxidative stress markers were measured. PA accelerated lipid metabolism derangement, inflammatory reaction and oxidative stress in podocytes. Overexpression of H-FABP enhanced the PA-induced disequilibrium in podocytes. The mRNA and protein expression levels of acyl-coenzyme A oxidase 3 and monocyte chemotactic protein 1, and the protein expression levels of 8-hydroxy-2'-deoxyguanosine and 4-hydroxynonenal were upregulated in the H-FABP overexpression group, while the mRNA and protein expression of peroxisome proliferator activated receptor α was downregulated. Knockdown of H-FABP inhibited the PA-induced injury and lipid metabolism derangement, as well as the inflammatory reaction and oxidative stress in podocytes. These results indicated that overexpression of H-FABP enhances fatty acid-induced podocyte injury, while H-FABP inhibition may represent a potential therapeutic strategy for the prevention of lipid metabolism-associated podocyte injury.

Inhibition of X-linked inhibitor of apoptosis protein enhances anti-tumor potency of pure total flavonoids on the growth of leukemic cells.

Flavonoids, a vast group of polyphenols widely distributed in plants, are known to possess a range of biological activities and potential anti-tumor effects. X-linked inhibitor of apoptosis protein (XIAP) promotes the progression of leukemia by preventing tumor cells undergoing apoptosis. The present study investigated the potential effects and underlying mechanisms of pure total flavonoids fromMacfad (PTFC) on human U937 cells, and explored the effects of short hairpin (sh)RNA-mediated XIAP knockdown on the anti-cancer effects of PTFC. Western blotting was used to determine level of apoptosis-associated effectors following PTFC treatment. A lentiviral vector of RNA interference of XIAP gene was constructed to downregulate XIAP expression. MTT assay and flow cytometry were used to determine the effects of PTFC separately or combined with XIAP-shRNA on inhibition and apoptosis of U937 cells, respectively. Treatment with PTFC effectively inhibited leukemic cell proliferation in a dose- and time-dependent manner. PTFC induced apoptosis of U937 cells in a dose-dependent manner, at a particular concentration range, by decreasing XIAP expression levels and activating caspases-3, -7 and -9. PTFC treatment combined with XIAP-shRNA additionally demonstrated a marked increase in cell apoptosis, compared with PTFC or XIAP-shRNA alone (P<0.05). Therefore, these findings suggest that PTFC inhibits growth and induces apoptosis in U937 cells. Furthermore, suppression of XIAP expression enhances these effects.

Long non-coding RNA 00312 downregulates cyclin B1 and inhibits hepatocellular carcinoma cell proliferation in vitro and in vivo.

Long non-coding RNAs are dysregulated in human hepatocellular carcinoma (HCC). We tested the potential effect of long non-coding RNA 00312 ("Lnc00312") on human HCC cell behavior in vitro and in vivo. Forced-expression of Lnc00312 by a lentiviral vector induced proliferation inhibition and apoptosis in HepG2 cells and primary human HCC cells. Lnc00312 downregulated cyclin B1 and induced G2-M cell cycle arrest in HCC cells. Restoring cyclin B1 expression by a cyclin B1 cDNA construct inhibited Lnc00312-induced cytotoxicity against HCC cells. Conversely, siRNA-mediated knockdown of Lnc00312 increased cyclin B1 expression and promoted HepG2 cell proliferation. In vivo, the growth of HepG2 xenograft tumors in severe combined immunodeficient (SCID) mice was largely inhibited after expression of Lnc00312. Significantly, Lnc00312 is downregulated in human HCC tissues, which is negatively correlated with the tumor grade. Overall, Lnc00312 inhibits human HCC cell proliferation in vitro and in vivo. Cyclin B1 could be a key target protein of Lnc00312 in human HCC cells.

AntogomiR-451 protects human gastric epithelial cells from ethanol via activating AMPK signaling.

The prevention and treatment efficiency of ethanol-induced gastric epithelial injury are not satisfied. We have previously shown that AMP-activated protein kinase (AMPK) activation exerts a pro-survival function in human gastric epithelial cells (GECs). miroRNA-451 ("miR-451")'s inhibitor, antagomiR-451, can activate AMPK signaling. In the present study, we show that forced-expression of antagomiR-451 via a lentiviral vector depleted miR-451, leading to AMPK activation in established GES-1 cells and primary human GECs. AntagomiR-451 efficiently protected GES-1 cells and primary human GECs from ethanol-induced viability reduction and apoptosis. AMPK activation is required for antagomiR-451-induced GEC protection. AMPKα1 knockdown (by targeted-shRNAs) or knockout (by CRISPR-Cas-9 KO plasmid) blocked antagomiR-451-induced AMPK activation, and GEC protection against ethanol. Further experimental results show that antagomiR-451 significantly attenuated ethanol-induced reactive oxygen species (ROS) production, lipid peroxidation and DNA damage. Collectively, antagomiR-451 protects human GECs from ethanol via activating AMPK signaling.
