Project description:Purpose: The goals of this study are to use RNA-seq to identify genes whose expression are regulated by protein ISGylation in a genome-wide scale Methods: mRNA profiles of PyVmT/Uba7 KO + Control and PyVmT/Uba7 KO+UBE1L mammary epithelial cells (MECs) were generated by deep-sequecing in duplicates, using Illumina HiSeq4000. Results: Using an optimized data analysis workflow, we mapped about 25 million sequence reads per sample to the mouse genome (M16 genome annotation). 259 genes are identified as differentially expressed transcripts from RNA-seq analysis of PyVmT/Uba7 KO + empty vector vs PyVmT/Uba7 KO + UBE1L MECs treated by LPS (100ng/mL) for 6 hours after IFN (1000 U/mL) priming for 24 hours. Conclusions: protein ISGylation facilitated expression of a group genes, which are regulated by STAT1/STAT2 containing complexes.

Project description:This paper presents a teleoperation system of robot grasping for undefined objects based on a real-time EEG (Electroencephalography) measurement and shared autonomy. When grasping an undefined object in an unstructured environment, real-time human decision is necessary since fully autonomous grasping may not handle uncertain situations. The proposed system allows involvement of a wide range of human decisions throughout the entire grasping procedure, including 3D movement of the gripper, selecting proper grasping posture, and adjusting the amount of grip force. These multiple decision-making procedures of the human operator have been implemented with six flickering blocks for steady-state visually evoked potentials (SSVEP) by dividing the grasping task into predefined substeps. Each substep consists of approaching the object, selecting posture and grip force, grasping, transporting to the desired position, and releasing. The graphical user interface (GUI) displays the current substep and simple symbols beside each flickering block for quick understanding. The tele-grasping of various objects by using real-time human decisions of selecting among four possible postures and three levels of grip force has been demonstrated. This system can be adapted to other sequential EEG-controlled teleoperation tasks that require complex human decisions.

Project description:We have carried out high-throughput profiling of histone modifications and transcription factors in mammalian cells. First we generated stable PHF6 knock out lines by CRISPR-Cas9 technology in wild type Jurkat cells. We electroporated the RNP complex in Jurkat cells conatining guide RNAs against either non-targeting (EV) or PHF6 (KO) followed by single clone isolation and expansion. We confirmed absolute loss of total protein by WB and indel formation (mutation efficiency) at the PHF6 genomic locus by Sanger sequencing. By obtaining over six to ten billion bases of sequence from chromatin immunoprecipitated DNA, we generated genome-wide chromatin-state maps of well studied histone modifications and transcription factors. This study provides a framework for eluciadting the role of PHF6 in regulating the chromatin landscape encompassing both activating and repressive histone modifications and chromatin remodelers in the context of leukemia.
