Estradiol could protect osteoblast against apoptosis, and apoptosis and autophagy were extensively and intimately connected. The aim of the present study was to test the hypothesis that autophagy was present in osteoblasts under serum deprivation and estrogen protected against osteoblast apoptosis via promotion of autophagy. MC3T3-E1 osteoblastic cells were(More)
Following the publication of this article, an interested reader drew to our attention an anomaly associated with the presentation of the western blots in Fig. 4B and C. These contained the same GAPDH control data, even though Fig. 4B and C were intended to show the inhibition of osteosarcoma cell migration by a recombinant adenovirus (ad) expressing bone(More)
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)
Age-related bone loss is a major cause of osteoporosis and osteoporotic fractures in the elderly. However, the underlying molecular mechanism of age-related bone loss is still poorly understood. The aim of this study was to clarify whether autophagy in osteocytes was involved in age-related bone loss. Male Sprague–Dawley (SD) rats in 3, 9, and 24 month old(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)
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)
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)
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)
BACKGROUND To investigate the in vitro inhibitory effects of PEI-RGD/125I-(αv)ASODN (PEI, polyethylenimine; RGD, Arg-Gly-Asp; ASODN, antisense oligodeoxynucleotide) on the growth and invasion of HepG2 cells. MATERIAL AND METHODS ASODN of the integrin αv-subunit was marked with 125I and underwent complexation with PEI-RGD, a PEI derivative. Next,(More)
