Hongjun Zhang, Jiao Zhou, Peng Xiao, Yong Lin, Xin Gong, Shiyan Liu, Qingjia Xu, Minjin Wang, Haiyan Ren, Mengji Lu, Yuan Wang, Jing Zhu, Zhiping Xie, Huihui Li & Kefeng Lu
Biogenesis of autophagosomes is the early step of macroautophagy/autophagy and requires membrane acquisition mainly from ER-Golgi-sourced precursor vesicles. Matured autophagosomes fuse with lysosomes for final degradation. However, how this selective fusion is determined remains elusive. Here, we identified Sac1 by a high throughput screen in Saccharomyces cerevisiae to show it was critical for autophagosome-lysosome fusion through its PtdIns4P phosphatase activity. Sac1 deficiency caused a dramatic increase of PtdIns4P at early Golgi apparatus and abnormal incorporation...

Likelihood ratio test for genetic association study with case–control data under Probit model

Zhen Sheng, Yukun Liu, Pengfei Li & Jing Qin
Probit and Logit models are the most popular for binary disease statusing in genetic association studies. They are equally used and nearly exchangeable in the analysis of prospectively collected data. However, no strong inferences were made based on Probit models for the retrospectively collected case–control data, especially in the presence of random effects. This paper systematically investigates the performance of Probit mixed-effects models for case–control data. We find that the retrospective likelihood has a closed-form,...
