Mallory, Paul A. Smith, Gabriela Schaepman-Strub, Steven J. Cooke

“…Addressing threats to biodiversity in the Arctic is further complicated by the region's complex geopolitics, as eight countries claim jurisdiction over the area, with multiple local considerations such as Indigenous sovereignty and resource rights. Here, we identify research priorities to serve as a starting point for addressing the most pressing threats to Arctic biodiversity. …”

The two-component system ArlRS is essential for wall teichoic acid glycoswitching in Staphylococcus aureus by Marieke M. Kuijk, Emma Tusveld, Esther Lehmann, Rob van Dalen, Iñigo Lasa, Hanne Ingmer, Yvonne Pannekoek, Nina M. van Sorge

“…Importantly, WTA glycosylation patterns show variation depending on environmental conditions, thereby impacting phage binding and interaction with host factors, such as antibodies and innate pattern-recognition receptors. Here, we show that the two-component system ArlRS is involved in the regulation of WTA glycosylation by responding to environmental changes in Mg2+ concentration. …”

A conserved element in the first intron of Cd4 has a lineage specific, TCR signal-responsive, canonical enhancer function that matches the timing of cell surface CD4 upregulation r... by Gregory A. Swan, Gregory A. Swan, Chika Fujii, Mia E. Guzynski, Sheridan M. Page, Isabelle V. Meyers, Yordan P. Penev, Sejiro Littleton, Sejiro Littleton, Adinda Azzahra, Christine Richardson, Sophia D. Sarafova, Sophia D. Sarafova

“…In this study, we investigate whether a conserved region, here called NCE, that is proximal to the Cd4 silencer and contains E4m has the required developmental-stage-specific canonical enhancer function and TCR responsiveness to mediate the CD4 upregulation required to prevent lineage errors.MethodsTo investigate the role of NCE, transient transfection of reporter plasmids was performed in thymoma cell lines arrested at the double-positive (DP, CD4+CD8+) and intermediate (INT, CD4+CD8lo) stages of development. …”

Alleviation of liver fibrosis by inhibiting a non-canonical ATF4-regulated enhancer program in hepatic stellate cells by Li-Xian Yang, Chuangye Qi, Si Lu, Xiang-Shi Ye, Parnaz Merikhian, Du-Yu Zhang, Tao Yao, Jiang-Sha Zhao, Ying Wu, Yongshi Jia, Bo Shan, Jinghai Chen, Xiaozhou Mou, Jia You, Wenbo Li, Yu-Xiong Feng

“…Abstract Liver fibrosis is a critical liver disease that can progress to more severe manifestations, such as cirrhosis, yet no effective targeted therapies are available. Here, we identify that ATF4, a master transcription factor in ER stress response, promotes liver fibrosis by facilitating a stress response-independent epigenetic program in hepatic stellate cells (HSCs). …”
