MicroRNA-1 inhibits tumorigenicity of esophageal squamous cell carcinoma and enhances sensitivity to gefitinib.

MicroRNA-1 inhibits tumorigenicity of esophageal squamous cell carcinoma and enhances sensitivity to gefitinib. Oncol Lett. 2018 Jan;15(1):963-971 Authors: Yu Q, Liu Y, Wen C, Zhao Y, Jin S, Hu Y, Wang F, Chen L, Zhang B, Wang W, Zhu Q, Guo R Abstract Dysregulation of microRNAs in various types of human cancer promote or suppress oncogenesis. MicroRNA (miR)-1 was previously revealed to function as a tumor suppressor in prostate cancer cells, and its expression was associated with reduced metastatic potential in lung cancer. The present study investigated the role of miR-1 and its association with phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit α (PIK3CA) in the pathophysiology of esophageal squamous cell carcinoma (ESCC), and analyzed the effects of miR-1 inhibitor or mimics on sensitivity to epidermal growth factor receptor-tyrosine kinase inhibitors, the alterations of cell cycle distribution and apoptosis in ESCC cells. Compared with normal tissues, the level of miR-1 expression was significantly lower and PIK3CA expression was higher in ESCC tissues. The level of miR-1 expression was also inversely associated with the level of PIK3CA mRNA expression. Low miR-1 and high PIK3CA expression levels were strongly associated with lymph node metastasis, and the level of miR-1 expression was negatively associated with clinical Tumor-Node-Metastasis stage. Furthermore, exogenous expression of miR-1 inhibited growth, arrested cell cycle in...

Authors: Schuler PJ, von Witzleben A, Doescher J, Wollenberg B, Dietz A, Hoffmann TK Abstract In recent years, immunotherapy has been shown to be a promising approach for the treatment of various tumor entities. Due to further pharmacological developments and new studies, the checkpoint inhibitors have now arrived in the clinic. To date, patients with cancers in the head and neck region have benefited from these agents as part of a palliative therapy. Current clinical trials are testing other indications for the checkpoint inhibitors as monotherapy or in combination with other therapeutic approaches. The ...

ConclusionsA small subset of pulmonary adenocarcinomas shows immunoreactivity for ER clones 6F11 and 1D5 in FNA samples (18.2% and 9.1%, respectively). The absence of immunoreactivity for ER‐SP1 clone indicates higher specificity of this clone in non‐breast tissue. The differential diagnostic value of all ER clones in malignant PEs appears to be secure. Larger studies are necessary to validate this observation.

A 38-year-old female, otherwise fit and well, presented with a mass on her left medial bulbar conjunctiva that had been enlarging for several months. Examinations showed a fixed pinkish tumour, 9 mm in maximum extent, spanning from the plica to the medial limbus. The tumour was removed in toto. Histology revealed it to be a biphasic tumour composed of lobules and infiltrative cords within a sclerotic matrix. The cells were spindle-shaped to epithelioid, with nuclear atypia and occasional mitotic figures. The tumour was positive for smooth muscle actin, beta-catenin, and vimentin. All other markers of myoepithelial differen...

Abstract Annexin A4 (Anxa4) is one of the Ca(2+)-regulated and phospholipid-binding annexin superfamily proteins. Anxa4 has a potential role in diagnosis, prognosis and treatment of certain cancers. Studies indicate that Anxa4 up-regulation promotes the progression of tumor and chemo-resistance of colorectal cancer (CRC), esophageal squamous cell carcinoma (ESCC), endometrial carcinoma (EC), gastric cancer (GC), chemo-resistant lung cancer (LC), malignant mesothelioma (MM), renal cell carcinoma (RCC), ovarian clear cell carcinoma (OCCC), cholangiocarcinoma, hepatocellular carcinoma (HCC), breast cancer (BC) and la...

Conclusions The positive rate of s-NY-ESO-1-Abs was significantly higher in patients with esophageal cancer than in patients with the other types of cancers. On the basis of its high specificity and sensitivity, even in patients with stage I tumors, s-NY-ESO-1-Abs may be one of the first choices for esophageal cancer.
