Tescalcin (TESC; also known as calcineurin B homologous protein 3, CHP3) has recently reported a regulator of cancer progression. Here, we showed that the elevation TESC in non-small cell lung (NSCLC) intensifies epithelial-mesenchymal transition (EMT) and stem (CSC) properties, consequently enhancing cellular resistance to γ-radiation. expression phosphorylation (consequent activation) signal transducer activator transcription 3 (STAT3) were upregulated CSC-like ALDH1high cells than...

Transmembrane 4 L6 family proteins have been known to promote cancer. In this study, we demonstrated that transmembrane member (TM4SF4), which is induced by γ-radiation in non-small cell lung cancer (NSCLC) cells, involved epithelial-to-mesenchymal transition (EMT) and stem (CSC) properties of NSCLC through the regulation osteopontin (OPN). Forced TM4SF4 overexpression A549 cells increased secretion OPN, activates CD44 or integrin signaling thus maintains EMT-associated CSC-like properties....

ABSTRACT— Intrahepatic distribution of Lipiodol and I‐131 infused via the hepatic arteries was evaluated in six patients with HCC who had undergone lobectomy or segmentectomy. CT scan gamma camera radiograph confirmed that oily contrast material radioactivity accumulated selectively tumor over a long period. One to two thirds mass appeared necrotic, although extent tended be larger case radioactive infusion. The cells contained numerous lipid globules within cytoplasm. Also, oil red 0 stain...

Introduction Bipolar Disorder (BD) is a disorder in which cognitive function relatively preserved but social functioning markedly impaired. Interestingly, studies on BD show that the patients have strong desire for rewards. Hypersensitivity to rewards has not yet been sufficiently examined through experimental methods, although recent pointed out their reward hypersensitivity cause of symptoms and dysfunction. Objectives The purpose this study was investigate whether with are hypersensitive...
