Cell Cycle: SGT1-HSP90 complex is required for CENP-A deposition at centromeres

August 17, 2017

Yohei Niikura,Risa Kitagawa,Hiroo Ogi &Katsumi Kitagawa ABSTRACT The centromere plays an essential role in accurate chromosome segregation, and defects in its function lead to aneuploidy and thus cancer. The centromere-specific histone H3 variant CENP-A is proposed to be the epigenetic mark of the centromere, as active centromeres require CENP-A–containing nucleosomes to direct the recruitment of multiple […]

CPRIT Grant: Recruitment of First-Time, Tenure-Track Faculty Members

August 16, 2017

“Big Data” is a driving force in cancer research today. Sifting through the data from thousands of cancer genomes will help researchers understand what drives cancer, and help them make predictions about therapies that will be most beneficial to individual patients. To help make sense of these data, and in particular, to apply the findings […]

Cancer Research: IGFBP7 Deletion Promotes Hepatocellular Carcinoma

August 1, 2017

Maaged Akiel, Chunqing Guo, Xia Li, Devaraja Rajasekaran, Rachel G. Mendoza, Chadia L. Robertson, Nidhi Jariwala, Fang Yuan, Mark A. Subler, Jolene Windle, Dawn K. Garcia, Zhao Lai, Hung-I Harry Chen, Yidong Chen, Shah Giashuddin, Paul B. Fisher, Xiang-Yang Wang and Devanand Sarkar Abstract Activation of IGF signaling is a major oncogenic event in diverse cancers, including hepatocellular carcinoma (HCC). In this setting, the insulin-like growth factor-binding protein IGFBP7 inhibits IGF signaling by binding the IGF1 receptor (IGF1R), functioning as a candidate tumor suppressor. IGFBP7 abrogates tumors by inhibiting angiogenesis and […]
