Protein disulfide isomerases (PDIs) negatively regulate ebolavirus structural glycoprotein expression in the endoplasmic reticulum (ER) via the autophagy-lysosomal pathway

Bin Wang, Jing Zhang, Xin Liu, Qingqing Chai, Xiaoran Lu, Xiaoyu Yao, Zhichang Yang, Liangliang Sun, Silas F. Johnson, Richard C Schwartz & Yong-Hui Zheng
Zaire ebolavirus (EBOV) causes a severe hemorrhagic fever in humans and non-human primates with high morbidity and mortality. EBOV infection is dependent on its structural glycoprotein (GP), but high levels of GP expression also trigger cell rounding, detachment, and downregulation of many surface molecules that is thought to contribute to its high pathogenicity. Thus, EBOV has evolved an RNA editing mechanism to reduce its GP expression and increase its fitness. We now report that the...

Proteotoxic stress disrupts epithelial integrity by inducing MTOR sequestration and autophagy overactivation

Xiaoxiang Cheng, Pei Zhang, Hongyu Zhao, Hui Zheng, Kai Zheng, Hong Zhang & Hongjie Zhang
Macroautophagy/autophagy, an evolutionarily conserved degradation system, serves to clear intracellular components through the lysosomal pathway. Mounting evidence has revealed cytoprotective roles of autophagy; however, the intracellular causes of overactivated autophagy, which has cytotoxic effects, remain elusive. Here we show that sustained proteotoxic stress induced by loss of the RING and Kelch repeat-containing protein C53A5.6/RIKE-1 induces sequestration of LET-363/MTOR complex and overactivation of autophagy, and consequently impairs epithelial integrity in C. elegans. In C53A5.6/RIKE-1-deficient animals, blocking...

An Optimal Hybrid Approach to Calculate Conditional Power

Jian Zhu, Xin Li & Yi Liu
When used in clinical trial adaptive designs, conditional power (CP) is most commonly calculated assuming the current trend, but this approach has been criticized for substantially deviating from the actual CP due to “double-dipping” the interim data (i.e., using the interim data as part of the final analysis test statistic and as the assumption for the remainder of the trial). By contrast, CP assuming the design assumption preserves the shape of the CP curve by...
