Social context affects tissue-specific copper distribution and behaviour of threespine stickleback (Gasterosteus aculeatus) by Sienna L. Overduin, Shaun S. Killen, Alex M. Zimmer, Jenelle D. McCuaig, Lucy Cotgrove, Isabel Aragao, Kelly J. Rozanitis, Kurt O. Konhauser, Daniel S. Alessi, Tamzin A. Blewett

“…We hypothesized that isolating threespine stickleback during a Cu exposure would increase Cu uptake and sublethal toxicity compared to a grouped exposure. Wild-caught fish were exposed to control, low Cu or high Cu conditions (0 – 150 µg/L of Cu, nominally), either in isolation or groups of six for 96 h. …”

Eugenia Delgado, Salvador Naranjo-Suarez, Marta Ramírez-Pedraza, Beatriz I. Cárdenas, Carmen Gallardo-Martínez, Alexandra Balvey, Eulalia Belloc, Judit Martín, Mark Boyle, Raúl Méndez, Mercedes Fernandez

“…In mouse models of diet-induced liver cancer (n = 10–15 per group), both systemic and hepatocyte-specific CPEB4 knockout mice exhibited significantly increased tumor burden compared with wild-type controls (p <0.05). In vitro studies using human and murine liver cancer cells (n = 3 biological replicates) demonstrated reduced sensitivity to ferroptosis upon CPEB4 depletion when induced by erastin or RSL3 (p <0.01). …”

Eichmüller, Patrick Schmidt, Frank Momburg, Miray Cetin, Felix Hartmann, Nektarios A. Valous, Albrecht Stenzinger, Laura Michel, Peter Lichter, Andreas Schneeweiss, Verena Thewes, Carlo Fremd, Inka Zörnig, Dirk Jäger

“…ScTCR Seq analysis revealed the presence of a clonotype in VILs that further expanded after a round of in vitro stimulation and validated to be specific against a private mutation, namely NCOR1L1475R, presented in the context of HLA-B * 07:02, with no reactivity to the wild-type peptide. Our study shows, for the first time, that tumor mutation – specific T cells are generated at high frequencies in the vaccination site and can be isolated with standard methods for TCR screening. …”

Reinvestigation into the role of lipopolysaccharide Glycosyltransferases in Helicobacter pylori protein glycosylation by Hong Li, Xiaoqiong Tang, Tiandi Yang, Tingting Liao, Aleksandra W. Debowski, Tiankuo Yang, Yalin Shen, Hans-Olof Nilsson, Stuart M. Haslam, Barbara Mulloy, Anne Dell, Keith A. Stubbs, Wolfgang Fischer, Rainer Haas, Hong Tang, Barry J. Marshall, Mohammed Benghezal

“…As LPS is a unique component of virtually all Gram-negative bacteria, our data suggest that when observing protein electrophoretic mobility shifts between wild-type and LPS mutant strains or between subcellular fractionation samples, the influence of LPS on protein electrophoretic migration should be considered first, rather than interpreting it as potential protein glycosylation that is dependent upon LPS biosynthetic pathway.…”
