Genome reannotation aims for complete and accurate characterization of gene models and thus is of critical significance for in-depth exploration of gene function. Although the availability of massive RNA-seq data provides great opportunities for gene model refinement, few efforts have been made to adopt these precious data in rice genome reannotation. Here we reannotate the rice (Oryza sativa L. ssp. japonica) genome based on integration of large-scale RNA-seq data and release a new annotation system IC4R-2.0. In general, IC4R-2.0 significantly improves the completeness of gene structure, identifies a number of novel genes, and integrates a variety of functional annota-tions. Furthermore, long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs) are system-atically characterized in the rice genome. Performance evaluation shows that compared to previous annotation systems, IC4R-2.0 achieves higher integrity and quality, primarily attributable to mas-sive RNA-seq data applied in genome annotation. Consequently, we incorporate the improvedannotations into the Information Commons for Rice (IC4R), a database integrating multiple omics data of rice, and accordingly update IC4R by providing more user-friendly web interfaces and implementing a series of practical online tools. Together, the updated IC4R, which is equipped with the improved annotations, bears great promise for comparative and functional genomic studies in rice and other monocotyledonous species. The IC4R-2.0 annotation system and related resources are freely accessible at http://ic4r.org/.

【Objective:】 To understand the current situation and influencing factors of ethical knowledge, attitude, and practice (KAP) among clinical researchers, enhance their ethical awareness, and improve the quality of clinical researches. 【Methods:】 A self-designed questionnaire was used to conduct a convenient sampling survey of medical staff who have participated in clinical study. 【Results:】 A total of 6,021 subjects were investigated, with males accounting for 28.46% and females accounting for 71.53%. The average age of them was (37.47±11.46) years old. The total score of ethics and the mean scores of the three dimensions of knowledge, attitude and practice were (70.62±12.99), (59.63±12.50), (79.55±19.62) and (74.92±18.29), respectively. Multiple linear regression analysis showed that researchers with male, tertiary hospitals, doctors, ethics-related part-time jobs, postgraduate education, associate senior title or above, and training experience scored higher (P<0.05). 【Conclusion:】 Ethical attitudes have a significant mediating effect between knowledge and practice, accounting for 62.72% of the total effect. Researchers recognize the importance of ethics, but it is urgent to strengthen their knowledge learning and practical application.

Macroautophagy (referred to as autophagy hereafter) is a major intracellular lysosomal degradation pathway that is responsible for the degradation of misfolded/damaged proteins and organelles. Previous studies showed that autophagy protects against acetaminophen (APAP)-induced injury (AILI) via selective removal of damaged mitochondria and APAP protein adducts. The lysosome is a critical organelle sitting at the end stage of autophagy for autophagic degradation via fusion with autophagosomes. In the present study, we showed that transcription factor EB (TFEB), a master transcription factor for lysosomal biogenesis, was impaired by APAP resulting in decreased lysosomal biogenesis in mouse livers. Genetic loss-of and gain-of function of hepatic TFEB exacerbated or protected against AILI, respectively. Mechanistically, overexpression of TFEB increased clearance of APAP protein adducts and mitochondria biogenesis as well as SQSTM1/p62-dependent non-canonical nuclear factor erythroid 2-related factor 2 (NRF2) activation to protect against AILI. We also performed an unbiased cell-based imaging high-throughput chemical screening on TFEB and identified a group of TFEB agonists. Among these agonists, salinomycin, an anticoccidial and antibacterial agent, activated TFEB and protected against AILI in mice. In conclusion, genetic and pharmacological activating TFEB may be a promising approach for protecting against AILI.
