Background In recent years, miR-152 has been dysregulated in a variety of tumors and used as a tumor suppressor. Nevertheless, its role in nasopharyngeal carcinoma (NPC) remains unidentified. Materials and methods Real-time quantitative PCR (polymerase chain reaction) was performed to analyze the expression of miR-152 in NPC cell lines. MiR-152 expression profiles in NPC tissues were obtained...

BACKGROUND miR-203a-3p was reported as a tumor suppressor and disregulated in many malignancies including nasopharyngeal carcinoma (NPC). However, its function in tumor growth and metastasis in NPC has rarely been reported. METHODS The expression level of miR-203a-3p in human NPC tissues and cell lines was detected via real-time PCR (RT-PCR). Cell proliferation, migration and invasion were as...

The anaphylatoxin C5a is a chemoattractant that can induce various inflammatory responses in vivo via the C5a receptor (C5aR). There is emerging evidence that C5a is generated in the cancer microenvironment. However, the role of C5a in human nasopharyngeal carcinoma (NPC) remains largely unclear. Thus, the present study aimed to examine the direct influence of C5a stimulation on the proliferati...

Nasopharyngeal carcinoma (NPC) is an Epstein-Barr virus-associated malignancy most common in East Asia, Africa and Alaska. Radiotherapy and cisplatin-based chemotherapy are the main treatment options. Unfortunately, disease response to concurrent chemoradiotherapy varies among patients with NPC, and many cases are resistant to cisplatin and radiotherapy. Signal transducer and activator of trans...

Interleukin (IL)-17A is a T helper (Th)17 cell-secreted cytokine that is able to induce various inflammatory responses. There is emerging evidence that IL-17A is generated in the cancer microenvironment of human nasopharyngeal carcinoma (NPC). However, the role of IL-17A in NPC remains unclear. Thus, the present study aimed to examine the direct influence of IL-17A stimulation on the proliferat...

The aim of the present study was to analyze the roles of T lymphoma invasion and metastasis 1 (Tiam1) in nasopharyngeal carcinoma (NPC) progression and its correlation with clinicopathological features, including the survival of patients with NPC. Tiam1 protein expression in NPC tissues was examined using immunohistochemistry. Reverse transcription-polymerase chain reaction (RT-PCR) and immunof...

El objetivo del presente estudio fue caracterizar 10 variedades de quinua (Chenopodium quinoa Willd.) y una variedad quelite cenizo album L.), diferente color planta producción materia seca en la parte aérea, por su contenido nitratos oxalatos completa (NPC, OPC), hojas (NH, OH) tallos (NT, OT), presencia alcaloides las etapas botón floral floración condiciones riego temporal o secano Montecill...

JCB • VOLUME 179 • NUMBER 7 • 2007 1328 The NPC, in detail T he nuclear pore complex (NPC) is a huge cylindrical assembly that transports material to and from the nucleus. In a biological tour de force, researchers have determined the positions of all 456 proteins of the NPC, providing structural insights of unprecedented detail. Among other discoveries, Svetlana Dokudovskaya, Liesbeth Veenhoff...

UNLABELLED Genetic factors, as well as environmental factors, play a role in development of nasopharyngeal carcinoma (NPC). A number of single nucleotide polymorphisms (SNPs) have been reported to be associated with NPC. To confirm these genetic associations with NPC, two independent case-control studies from Southern China comprising 1166 NPC cases and 2340 controls were conducted. Seven SNPs ...

In the U.S., nasopharyngeal carcinoma (NpC) kills >7,600 each year. Deaths are predominantly among adult men, and in most cases, early detection and treatment can save lives. Despite the annual spending of approximately 3.2 billion dollars on head and neck cancer research, NpC remains a neglected disease since its fatality rates are among the lowest nation wide. The relative survival rates from...
