Increasing evidence and indications showed that cell fusion is crucial in tumor development and metastasis, and hypoxia, a closely linked factor to tumor microenvironment, which can lead to EMT, induces angiogenesis and metastasis in tumor growth. However, the relationship between hypoxia and fusion has not been reported yet. EMT will change some proteins in the epithelial cell surface and the ...

Hypoxia is an important regulator of normal and cancer stem cell (CSC) differentiation. Colorectal CSCs from SW1222, LS180, and CCK81 colorectal cancer-derived cell lines are able to differentiate into complex 3D lumen-containing structures in normoxia, whereas in hypoxia, they form undifferentiated dense colonies that have reduced expression of the enterocyte differentiation marker CDX1, lack ...

Abstract Objectives Gliomas are highly aggressive neuroepithelial-layer malignancies. Hypoxia-inducible factor 1α (HIF-1α) was revealed to be upregulated in gliomas under hypoxia. Nevertheless, its role glioma cells remains elusive. We attempted clarify the molecular mechanism of HIF-1 underlying glioma. Methods Cellular models were established mimic characteristics RT‒qPCR used detect HIF-1α a...

As one of the most common malignancies worldwide, Hepatocellular carcinoma (HCC) has been treated by Sorafenib, which is first approved target drug FDA for advanced HCC. However, resistance obstacles to its application. a typical characteristic solid tumors, hypoxia become key cause chemotherapy and radiotherapy. It important elucidate underlying mechanisms Sorafenib under hypoxia. In this stud...

Small cell lung carcinoma (SCLC) is extremely aggressive and frequently metastasizes widely in its early stage. Because tumor hypoxia is related to aggressive tumor behavior and the hypoxic adaptation of SCLC is poorly documented, we stained SCLC tumors arranged in a tissue microarray for hypoxia-inducible factor (HIF)-1α and HIF-2α proteins. We found an overall lack of HIF-2α protein expressio...

The hypoxic microenvironment of solid tumors is associated with malignant progression and it renders tumors more resistant to cancer therapies. Endothelial cell damage may occur following hypoxic conditions and lead to dysfunction; however, endothelial cells in tumors survive hypoxic conditions providing nutrients and oxygen to facilitate tumor growth. In this study, we investigated the effects...

Patients with non-small cell lung cancer (NSCLC) with echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase (ALK) rearrangements generally respond to ALK inhibitors such as crizotinib. However, some patients with EML4-ALK rearrangements respond poorly to crizotinib. Hypoxia is involved in the resistance to chemotherapeutic treatments in several cancers, and we inves...
