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...

Molybdopterin biosynthesis pathway contributes to the regulation of SaeRS two-component system by ClpP in Staphylococcus aureus

Na Zhao, Yanan Wang, Junlan Liu, Ziyu Yang, Ying Jian, Hua Wang, Mahmoud Ahmed, Min Li, Taeok Bae & Qian Liu
In Staphylococcus aureus, the SaeRS two-component system is essential for the bacterium’s hemolytic activity and virulence. The Newman strain of S. aureus contains a variant of SaeS sensor kinase, SaeS L18P. Previously, we showed that, in the strain Newman, SaeS L18P is degraded by the membrane-bound protease FtsH. Intriguingly, the knockout mutation of clpP, encoding the cytoplasmic protease ClpP, greatly reduces the expression of SaeS L18P. Here, we report that, in the strain Newman, the...

Acetylation of SCFD1 regulates SNARE complex formation and autophagosome-lysosome fusion

Hong Huang, Qinqin Ouyang, Kunrong Mei, Ting Liu, Qiming Sun, Wei Liu & Rong Liu
SCFD1 (sec1 family domain containing 1) was recently shown to function in autophagosome-lysosome fusion, and multiple studies have demonstrated the regulatory impacts of acetylation (a post-translational modification) on macroautophagy/autophagy. Here, we demonstrate that both acetylation- and phosphorylation-dependent mechanisms control SCFD1ʹs function in autophagosome-lysosome fusion. After detecting a decrease in the extent of SCFD1 acetylation under autophagy-stimulated conditions, we found that KAT2B/PCAF catalyzes the acetylation of residues K126 and K515 of SCFD1; we also showed that...
