Autophagy differs from apoptosis and is independent of phagocytes by the appearance of autophagosomes, autolysosomes, and complete nuclei in the cell. This process significantly contributes to the antineoplastic effects of radiation. Radiation is an important strategy in cancer treatment; however, many types of cancer show radioresistance. The effects of(More)
Hypoxia is a widespread phenomenon present in many human solid tumors and is associated with a poor prognosis and therapy resistance. Here, we tested the feasibility of melittin, a major component of bee venom, on radiosensitization of hypoxic head and neck squamous cell carcinoma (HNSCC). CNE-2 and KB cells were treated with melittin and radiation response(More)
Radiotherapy is a widespread treatment in human solid tumors. However, therapy resistance and poor prognosis are still problems. Gambogic acid (GA), extracted from the dried yellow resin of gamboges, has an anticancer effect against various types of cancer cells. To explore the radiosensitivity of GA on esophageal cancer cell line TE13, cell viability was(More)
This study was designed to identify candidate single-nucleotide polymorphisms (SNPs) that may affect the susceptibility to esophageal squamous cell carcinoma (ESCC) and elucidate their potential mechanisms to generate SNP-to-gene-to-pathway hypotheses. A genome-wide association study (GWAS) dataset for ESCC, which included 453,852 SNPs from 1898 ESCC(More)
The growth of solid tumors requires angiogenesis to provide oxygen and nutrients and to support cell proliferation. The switch from an avascular to a vascular phenotype is typically related to acceleration of tumor growth. Anti-angiogenic therapy is becoming a very promising way for malignant tumors. Meanwhile, malignant tumor cells themselves were able to(More)
AIMS Hypoxia is an important factor that causes decreased local disease control as well as increased distant metastases and resistance to radiotherapy in patients with advanced nasopharyngeal carcinoma (NPC). Gambogic acid (GA), the major active ingredient of gamboge, exerts antitumor effects in vitro and in vivo. However, the molecular mechanism by which(More)
The aim of this study was to investigate the effect of recombinant human endostatin (rh-Endo) in combination with radiation therapy (RT) on esophageal squamous cell carcinoma (ESCC) and explore the potential mechanisms. ECA109-bearing nude mice were administered RT and/or rh-Endo treatment. Tumor volume, survival, hypoxia and vascular parameters were(More)
