esophageal neoplasms/hypoxia

BACKGROUND Metastasis to regional lymph nodes represents the first step of dissemination in esophageal cancer and serves as an unfavorable prognostic indicator for disease progression. The formation of tumor lymphatic microvessels is dependent on the production of lymphangiogenic growth factors by

To evaluate the effect of different regimen of radiotherapy on multidrug resistance 1 (MDR1) expression and analyze the role hypoxia-inducible factor 1α (HIF1α) played in the whole process. Fifty-four cell lines established from 96 esophageal cancer biopsy samples were given various doses of

In 89 patients with esophageal cancer, postoperative pulmonary and renal functions, circulatory status and renin-angiotensin-aldosterone system were studied to elucidate the mechanism for renal dysfunction to effect on hypoxia. Renal function fell on early postoperative day, and the free water

To demonstrate effects of antisense VEGF(165) to suppress esophageal cancer cells and to improve efficacy of the gene therapy of tumor by using hypoxic environment, hypoxia response element (HRE) was cloned from promoter of VEGF by PCR and employed to construct an eukaryotic expression vector

Background: Propofol has been reported to be related to the migration, invasion, and epithelial-mesenchymal transition (EMT) of esophageal cancer (EC) cells. However, the detailed mechanism has not yet been fully reported. The purpose of

Extracellular matrix metalloproteinase inducer (EMMPRIN) exerts important roles in tumor progression, including angiogenesis, metastasis and therapy resistance. The epithelial‑mesenchymal transition (EMT), which is induced by hypoxia, is an important process in cancer metastasis. However, the

Brucea javanica oil emulsion (BJOE) has been used clinically to treat esophageal cancer combined with radiotherapy for numerous years in China. However, the detailed mechanism remains unclear. Thus, the effects of BJOE on the radiosensitivity of esophageal squamous cell carcinoma (ESCC) were

OBJECTIVE The aim of this study was to examine the effects of hypoxia on radiosensitivity and to analyze the mechanisms responsible for radiation resistance in gastric and esophageal cancer. METHODS A gastric cancer cell line, OCUM-12, and an esophageal cancer cell line, TE-6, were used. The effects

Hypoxia inducible factor 1a and 2a (HIF-1a and HIF-2a) are key proteins regulating cellular response to hypoxia. Because the efficacy of photodynamic therapy (PDT) is dependent on the presence of oxygen, the assessment of HIF-1a and HIF-2a expression may be of value in predicting clinical response

Acquired radioresistance is a major clinical obstacle in the treatment of esophageal cancer (EC). Ubiquitin-specific protease 28 (USP28) has been implicated in tumor growth in various cancer types. However, the role of USP28 and its underlying mechanisms of radioresistance in EC remain unknown. In

In this systematic review, the existing evidence of available hypoxia-associated molecular response biomarkers in esophageal cancer (EC) patients is summarized and set into the context of the role of hypoxia in the prediction of esophageal cancer, treatment response and treatment outcome. A

Hypoxia inducible factor (HIF)-1alpha is a transcription factor that regulates the transcription of genes associated with cell proliferation and vascular development. In various cancer tissues, HIF-1alpha is associated with clinicopathological factors, such as the tumor size, histological grade, and
