Transforming growth factor-β activated kinase-1 (TAK1) is an essential regulator in toll-like receptor (TLR), tumor necrosis factor (TNF) and interleukin-1 (IL-1) signaling pathways, and plays very important roles in animal innate immunity. TAK1-binding protein, TAB1, can specifically regulate the activation of TAK1. However, the TAB1 gene in amphioxus has not yet been identified to date. In this...
Complement factor H (CFH) is an essential regulator of the complement system and plays very important roles in animal innate immunity. Although the complement system of amphioxus has been extensively studied, the expression in amphioxus and evolution of CFH gene remain unknown. In this study, we identified and characterized an amphioxus (Branchiostoma belcheri) CFH gene (designated as AmphiCFH). Our...
MicroRNAs (miRNAs) are strongly implicated in many cancers, including breast cancer. Recently, microRNA-301a (miR-301a) has been proved to play a substantial role in gastric cancer, but its functions in the context of breast cancer remain unknown. Here we report that miR-301a was markedly upregulated in primary tumor samples from patients with distant metastases and pro-metastatic breast cancer cell...
ΔNp73 has emerged as an interesting novel factor in cancer research. Here, we report the effect of carbon-ion beams on ΔNp73 expression in human cervix carcinoma HeLa cells in contrast to the effect of X-rays. Cellular sensitivities were determined by colony formation. Radiation-induced cell cycle arrest was investigated with flow cytometry. Additionally, radiation-induced apoptosis was analyzed with...
MicroRNAs (miRNAs) participate in various biological processes via controlling gene activity. Amphioxus is the best available stand-in as the proximate invertebrate ancestor of the vertebrates. Here, we systematically investigated the miRNAs in amphioxus. First, we identified 245 candidate amphioxus miRNAs, in which 183 miRNAs were firstly reported. Second, we gave evidences to support a birth-and-death...
