In vitro measurement of glucose uptake after radiation and cetuximab treatment in head and neck cancer cell lines using 18F-FDG, gamma spectrometry and PET/CT.

In conclusion, a novel yet reliable method for the measurement of intracellular 18F-FDG via GS has been developed, and our results indicate that 18F-FDG uptake is associated with radiation and cetuximab response in HNSCC. PMID: 31620196 [PubMed]

ConclusionNo significant outcome differences were observed between more or less hypoxic tumours, as determined by the 15-gene hypoxia classifier. These results suggest that the 15-gene hypoxia classifier may not have prognostic value in an OPC patient cohort treated with accelerated chemoradiotherapy.

ConclusionsErbB3 overexpression predicts a poor clinical outcome. Sapitinib was shown to be an effective inhibitor in the HNSCC cell line and animal models of cancer but with no statistical significance. Further studies with larger groups are needed to better support these results.

This study provides us with a new insight that multiple miRNAs can be together used for predicting the prognosis of patients with HNSCC. In order to further confirm the prognostic value of the 2 miRNA signatures, our future research may focus on exploring the relationship between miRNA and genic profile of HNSCC. AbstractMicroRNAs(miRNAs) are maladjusted in multifarious malignant tumor and can be considered as both carcinogens and tumor ‐inhibiting factor. In the present study, we analyzed the miRNAs expression profiles and clinical information of 481 patients with head and neck squamous cell carcinoma (HNSCC) through th...

Abstract Recent research have proved that miR-501-5p acted as a potent tumor biomarker in several cancers, excluding head and neck squamous cell carcinoma (HNSCC). The study intends to discover the potential function and mechanism of miR-501-5p in HNSCC. Data from TCGA database and qRT-PCR estimated the expression of miR-501-5p and Calcium activated Chloride Channel A4 (CLCA4). Cell proliferation, clone formation and transwell assays were performed to explore HNSCC cells biological behaviors. Luciferase assay was carried out to identify the interaction between miR-501-5p and CLCA4. miR-501-5p was profoundly up-reg...

Dikomey Wittig Arenz The PI3K/Akt/mTOR pathway is frequently altered in human papillomavirus (HPV)-positive and negative squamous cell carcinoma of the head and neck (HNSCC) and overstimulation is associated with poor prognosis. PI3K drives Akt activation and constitutive signaling acts pro-proliferative, supports cell survival, DNA repair, and contributes to radioresistance. Since the small molecule NVP-BEZ235 (BEZ235) is a potent dual inhibitor of this pathway, we were interested whether BEZ235 could be an efficient radiosensitizer. The 50 nM BEZ235 was found to abrogate endogenous and irradiation-induced pho...

m Eun Jung Dendrobii Herba is an herbal medicine that uses the stems of Dendrobium species (Orchidacea). It has been traditionally used to treat fever, hydrodipsomania, stomach disorders, and amyotrophia. In our previous study, a bibenzyl compound, moscatilin, which is isolated from Dendrobii Herba, showed potent cytotoxicity against a FaDu human pharyngeal squamous carcinoma cell line. Prompted by this finding, we performed additional studies in FaDu cells to investigate the mechanism of action. Moscatilin induced FaDu cell death by using 5 μM of concentration and by mediating apoptosis, whereas cell prol...
