Malignant glioblastoma multiforme (GBM) is an aggressive brain tumor with strong local invasive growth and a poor prognosis. One probable way to manipulate GBM cells toward a less invasive status is to reprogram the most malignant GBM cells to a more differentiated and less oncogenic phenotype. Herein, we identified a novel role of a RING finger protein Znf179 in gliomagenesis.

Fetal bovine serum (FBS) is depended upon by investigators as an indispensable supplement in cell and tissue culture systems. Due to increased demand and limited availability, the price of FBS has increased by greater than 300% in the past few years. In addition, there are ethical and scientific controversies about the collection and use of FBS in culture systems.

High-mobility group AT-hook 2 (HMGA2) is an architectural transcription factor that is expressed in many human neoplasms. Oral squamous cell carcinoma (OSCC) is one of the leading cancers in the world, particularly in Southeast Asia. In this study, the expression level of HMGA2 was determined on tissue microarray of OSCC and its correlation with prognosis of patients was studied.

Lytic reactivation of EBV has been reported to play an important role in human diseases, including NPC carcinogenesis. Inhibition of EBV reactivation is considered to be of great benefit in the treatment of virus-associated diseases. For this purpose, we screened for inhibitory compounds and found that apigenin, a flavonoid, seemed to have the ability to inhibit EBV reactivation.

Increased expression of DEF6 is correlated with the malignant behavior of various cancers. Both DEF6 and p16 contribute to the regulation of cell cycle progression, and p53 plays important role in the cell cycle checkpoints. This study was designed to elucidate the prognostic significance of DEF6, p53 and p16 immunoexpressions in different histology subtypes of ovarian carcinoma.

The lytic reactivation of Epstein-Barr virus (EBV) has been reported to be strongly associated with several human diseases, including nasopharyngeal carcinoma (NPC). Inhibition of the EBV lytic cycle has been shown to be of great benefit in the treatment of EBV-associated diseases. The administration of dietary compounds is safer and more convenient than other approaches to preventing EBV reactivation.

Nasopharyngeal carcinoma (NPC) is a malignancy derived from the epithelial cells of the nasopharynx. Although a combination of radiotherapy with chemotherapy is effective for therapy, relapse and metastasis after remission remain major causes of mortality. Epstein-Barr virus (EBV) is believed to be one of causes of NPC development.

Dengue is the most widespread arbovirus infection and poses a serious health and economic issue in tropical and subtropical countries. Currently no licensed vaccine or compounds can be used to prevent or manage the severity of dengue virus (DENV) infection. Honokiol, a lignan biphenol derived from the Magnolia tree, is commonly used in Eastern medicine.

(-)-Epigallocatechin-3-gallate (EGCG), a major green tea polyphenol, has been shown to inhibit the proliferation of a variety of tumor cells. Epidemiological studies have shown that drinking green tea can reduce the incidence of nasopharyngeal carcinoma (NPC), yet the underlying mechanism is not well understood. In this study, the inhibitory effect of EGCG was tested on a set of Epstein Barr virus-negative and -positive NPC cell lines.

Nasopharyngeal carcinoma (NPC) is a head and neck cancer prevalent throughout Southern China and Southeast Asia. Patient death following relapse after primary treatment remains all too common but the cause of NPC relapse is unclear. Clinical and epidemiological studies have revealed the high correlation among NPC development, Epstein-Barr virus (EBV) reactivation and host genomic instability.

N-nitroso compounds (NOCs) and Epstein-Barr virus (EBV) reactivation have been suggested to play a role in the development of nasopharyngeal carcinoma (NPC). Although chemicals have been shown to be a risk factor contributing to the carcinogenesis of NPC, the underlying mechanism is not fully understood. We demonstrated recently that N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) enhances the genomic instability and tumorigenicity of NPC cells via induction of EBV reactivation.

Seroepidemiological studies imply a correlation between Epstein-Barr virus (EBV) reactivation and the development of nasopharyngeal carcinoma (NPC). N-nitroso compounds, phorbols, and butyrates are chemicals found in food and herb samples collected from NPC high-risk areas. These chemicals have been reported to be risk factors contributing to the development of NPC, however, the underlying mechanism is not fully understood.

Epstein-Barr virus (EBV) has been associated with several human malignancies including nasopharyngeal carcinoma (NPC). Reactivation of latent EBV has been considered to contribute to the carcinogenesis of NPC. Blocking the EBV lytic cycle has been shown effective in the treatment of EBV-associated diseases.

Seroepidemiological studies implicate a correlation between Epstein-Barr virus (EBV) reactivation and the development of nasopharyngeal carcinoma (NPC). Moreover, N-nitroso compounds are known chemical carcinogens in preserved foodstuffs and cigarettes and have been implicated as risk factors contributing to the development of NPC. Here, NPC cell lines latently infected with EBV, NA and HA, and the corresponding EBV-negative NPC cell lines, NPC-TW01 and HONE-1, were used as the model system in this study.

Epstein-Barr Virus (EBV) DNase (BGLF5) is an alkaline nuclease and has been suggested to be important in the viral life cycle. However, its effect on host cells remains unknown. Serological and histopathological studies implied that EBV DNase seems to be correlated with carcinogenesis.

Nasopharyngeal carcinoma is an epithelial malignancy with a remarkable racial and geographic distribution. Previous cytogenetic studies have shown nasopharyngeal carcinoma to be characterized by gross genomic aberrations. However, identification of susceptible gene loci in advanced nasopharyngeal carcinoma has been poorly discussed.

Nasopharyngeal carcinoma (NPC) is an endemic malignancy prevalent in South East Asia. Epidemiological studies have associated this disease closely with Epstein-Barr virus (EBV) infection. Previous studies also showed that EBV reactivation is implicated in the progression of NPC.

Nasopharyngeal carcinoma (NPC) is closely associated with Epstein-Barr virus (EBV) infection and exposure to environmental carcinogens. In this study, an inducible Epstein-Barr virus (EBV) reactivation NPC cell line, NA, was used to investigate the impact of recurrent 12-O-tetradecanoylphorbol-13-acetate-sodium n-butyrate (TPA/SB) treatment and EBV reactivation on chromosomal abnormalities utilizing array-based comparative genomic hybridization (CGH). It was observed that most copy-number aberrations (CNA) were progressively nonrandomly clustered on chromosomes 3, 8, and 9, as the frequency of TPA/SB treatment and EBV reactivation increased.

The Epstein-Barr virus (EBV) has been implicated in the development of many human neoplasias including B lymphoma and nasopharyngeal carcinoma. EBV latent membrane protein 1 (LMP1) is essential to virus-induced B cell immortalization and the downregulation of cell adhesion molecules that increases cell motility. Therefore, identifying LMP1 activity modulation methods may lead to the development of new therapies for LMP1-positive tumors.

Porcine cell and organ transplantation provides promise for maintaining normal physiological conditions in patients with end-stage organ failure. The approach however poses serious risk of transmitting pig pathogens to humans. Among many potential pathogens, porcine endogenous retroviruses (PERV) are of particular concern due to their ubiquitous nature in pigs and capability of infecting human cells.

Epstein-Barr virus (EBV) has been implicated in the development of many human neoplasias including B lymphomas and nasopharyngeal carcinoma (NPC). The EBV latent membrane protein 1 (LMP-1) has been found to participate in diverse cellular signaling pathways and is essential for virus-induced B-cell immortalization. In order to determine quantitatively the amount of LMP-1 in cells, five monoclonal antibodies (Mabs) specific to LMP-1 were generated.
