Cetuximab plus chemotherapy for advanced gastric cancer (GC) shows an active result in phase 2 trials. Unfortunately, Combination of cetuximab does not provide enough benefit to chemotherapy alone in phase 3 trials. Studies have demonstrated that berberine can suppress the activation of EGFR in tumors. In this study, we evaluated whether berberine could enhance the effects of EGFR-TKIs in GC cell lines and xenograft models. Our data suggest that berberine could effectively enhance the activity of erlotinib and cetuximab in vitro and in vivo...

The aim of this study is to investigate the frequency distribution of exon 3 deleted (d3-GHR) genetic polymorphism of growth hormone receptor (GHR) in growth hormone deficient (GHD) Chinese children and to explore the correlation between the growth promoting effects of recombinant human growth hormone (rhGH) and exon 3 genetic polymorphism of GHR in GHD children. In this study, 111 GHD (excluded small for gestational age) children were treated with rhGH (0.20 mg/kg/week) for six months. The body height (Ht), body weight, bone age (BA) and growth velocity (GV) were measured before and after six months of treatment...

BACKGROUND & AIMS: Inflammation regulated by interleukin (IL) 8 promotes metastasis of hepatocellular carcinoma (HCC). The transcription factor forkhead box C1 (FOXC1) promotes metastasis by activating the epithelial to mesenchymal transition; its levels in liver tumors have been associated with shorter survival times of patients. We investigated whether FOXC1 activates inflammation signaling pathways in HCC cell lines. METHODS: We performed studies in the human HCC cell lines Huh-7 and SMMC7721, as well as the metastatic cell lines MHCC97H and HCCLM3...

UNLABELLED: Metastasis is the main reason for high recurrence and poor survival of hepatocellular carcinoma (HCC) after curative resection. However, the molecular mechanism underlying HCC metastasis remains unclear. Here, we report on a novel function of SRY (sex determining region Y)-box 12 (Sox12), a member of the SYR-related high mobility group box family proteins, in promoting HCC metastasis. Overexpression of Sox12 was significantly correlated with loss of tumor encapsulation, microvascular invasion, and a higher tumor-nodule-metastasis (TNM) stage and indicated poor prognosis in human HCC patients...

MicroRNAs (miRNAs) are thought to have an important role in tumor metastasis by regulating diverse cellular pathways. Here, we describe the function and regulation network of miR-206 in gastric cancer (GC) metastasis. MiR-206 expression was downregulated in GC cells especially in high metastatic potential cells and was also significantly decreased in metastatic lesions compared with their corresponding primary tumor samples. Both gain- and loss-of-function studies confirmed that miR-206 significantly suppressed GC cell invasion and metastasis both in vitro and in vivo...

BACKGROUND: FOXJ1 is a member of the forkhead transcription factor family, which has been mostly studied for its role in the development of ciliated epithelium and immunology. However, the role of FOXJ1 in tumorigenesis remains largely unknown or even conflicting. We thus investigated FOXJ1 expression in gastric cancer and analyzed its correlations with tumor progression and prognosis. METHODS: The expression of FOXJ1 was detected by immunohistochemistry in 105 gastric cancer samples and adjacent noncancerous tissues...

The aim of this study was to investigate incidence trend of childhood type 1 diabetes in Shanghai, a megalopolis in east China. We established a population-based retrospective registry for the disease in the city's registered population during 1997-2011 and collected 622 incident type 1 diabetes in children aged 0-14 years. Standardized incidence rates and 95 % CI were estimated by applying the capture-recapture method and assuming Poisson distribution. Incidence trend was analyzed using the Poisson regression model...

Understanding the mechanism underlying multidrug resistance and identifying effective targets that can overcome it is of critical importance. In this study, mRNA and miRNA expression profiling of the drug resistant sublines, SGC7901/VCR and SGC7901/ADR, and their parental gastric cancer cell line SGC7901 were performed. A significant number of genes and a limited subset of miRNAs were commonly dysregulated, which were further validated using qRT-PCR. GO and KEGG pathway analyses of the commonly dysregulated genes indicated that the MAPK signalling pathway may be involved in multidrug resistance, which was further validated using immunoblotting and MTT assay...

UNLABELLED: Forkhead box Q1 (FoxQ1) is a master regulator of tumor metastasis. However, the molecular mechanism of FoxQ1 in regulating hepatocellular carcinoma (HCC) metastasis remains unknown. Here we report a novel function for FoxQ1 in modifying the tumor microenvironment to promote HCC metastasis. FoxQ1 expression was an independent and significant risk factor for the recurrence and survival in two independent cohorts totaling 1,002 HCC patients. FoxQ1 induced epithelial-mesenchymal transition (EMT) through the transactivation of ZEB2 expression by directly binding to the ZEB2 promoter...

In this study, we detected miR-206 expression in gastric cancer (GC) and further investigated its effects on GC cell growth in vitro and in vivo. miR-206 expression was found to be significantly decreased in 30 GC samples and GC cell lines by real time-PCR. Restoration of miR-206 reduced cell growth and colony forming ability in GC cells with G0/G1 cell cycle arrest. Further studies demonstrated that miR-206 could suppress GC cells proliferation at least partially through targeting the cyclinD2 (CCND2). Therefore, we provided evidence that miR-206 was a potential tumor suppressor and may be used as a therapeutic target for gastric cancer...

The proliferation-specific transcription factor Forkhead box M1 (FoxM1) acts as a master regulator of cancer cell growth and survival and plays an important role in the development of hepatocellular carcinoma. However, the molecular mechanisms that regulate FoxM1 expression remain largely unknown. In the current study, we demonstrated that tumor necrosis factor (TNF)-αα induced FoxM1 expression and transactivated its promoter activity in hepatoma cells. Serial 5" deletion and site-directed mutagenesis revealed that the induction of FoxM1 expression by TNF-α was dependent upon the hypoxia-inducible factor 1 (HIF1)-1 and HIF1-3/4 binding sites within the FoxM1 promoter...

BACKGROUND: An assessment was made of the toxicity of imperatorin and osthole identified in Cnidium monnieri fruit, 11 related compounds and five insecticides to larvae from insecticide-susceptible Culex pipiens pallens (KS-CP strain) and Aedes aegypti and wild C.p. pallens (YS-CP colony) using a direct-contact mortality bioassay. Results were compared with those of the conventional larvicide temephos. RESULTS: Imperatorin (LC(50) = 3.14 and 2.88 mg L(-1) ) was 1...

Toxicities of (E)-cinnamaldehyde and (E)-cinnamic acid and their 41 structurally related compounds to adult Dermatophagoides farinae Hughes and Dermatophagoides pteronyssinus Trouessart (Acari: Pyroglyphidae) were examined using fabric-circle contact plus fumigant and vapor-phase mortality bioassays. Results were compared with those of two acaricides, benzylbenzoate and dibutyl phthalate. In contact plus fumigant mortality bioassays, the most toxic compounds were (E)-cinnamaldehyde, methyl (E)-cinnamate, cinnamyl acetate, and hydrocinnamaldehyde against adult D...

OBJECTIVE: We investigated the correlation between the growth hormone receptor (GHR) exon 3 polymorphism and the metabolic profiles of Chinese children with obesity. SUBJECTS AND METHODS: A total of 409 obese/overweight children and 206 normal weight children were recruited. Anthropological and biochemical indexes including insulin and lipid profiles were measured. Genomic DNA was extracted from the peripheral blood leukocytes, and the GHR exon 3 polymorphism was genotyped by polymerase chain reaction...
