Functional and Structural Consequences of Nine CYP21A2 Mutations Ranging from Very Mild to Severe Effects by Débora de Paula Michelatto, Leif Karlsson, Ana Letícia Gori Lusa, Camila D’Almeida Mgnani Silva, Linus Joakim Östberg, Bengt Persson, Gil Guerra-Júnior, Sofia Helena Valente de Lemos-Marini, Michela Barbaro, Maricilda Palandi de Mello, Svetlana Lajic

“…The maximum velocity was decreased for all mutants except for p.Leu12Met. We conclude that p.Leu12Met is a normal variant; the mutations p.Arg16Cys, p.Ser101Asn, p.Ser202Gly, p.Pro267Leu, and p.Thr450Met could be associated with very mild nonclassic CAH, and the mutations p.Ser113Phe, p.Gln389_Ala391del, and p.Thr450Pro are associated with classic CAH. …”

Pseudovibriamides from Pseudovibrio marine sponge bacteria promote flagellar motility via transcriptional modulation by Yitao Dai, Vitor Lourenzon, Laura P. Ióca, Dua Al-Smadi, Lydia Arnold, Ian McIntire, Roberto G. S. Berlinck, Alessandra S. Eustáquio

“…RNA-sequencing transcriptomic analyses of strains having different compositions of pseudovibriamides suggested that both pseudovibriamides A and B affect genes potentially involved in motility, and that a compensatory mechanism is at play in mutants that produce only pseudovibriamide A, resulting in comparable flagellar motility as the wild type. …”

Bifurcation analysis of multistability and hysteresis in a model of HIV infection by I. V. Mironov, M. Yu. Khristichenk, Yu. M. Nechepurenko, D. S. Grebennikov, G. A. Bocharov

“…The model describes the most important blocks of the processes of interaction between viruses and the human body, namely, the spread of infection in productively and latently infected cells, the appearance of viral mutants and the development of the T cell immune response. …”

Understanding phage BX-1 resistance in Vibrio alginolyticus AP-1 and the role of quorum-sensing regulation by Xiaoyu Li, Xin Liu, Tianyi Ma, Haochen Su, Bingrui Sui, Lili Wang, Bilal Murtaza, Yongping Xu, Na Li, Demeng Tan

“…In this study, we isolated a novel Myoviridae phage, BX-1, capable of infecting Vibrio alginolyticus AP-1, and characterized its resistant mutants. We elucidated the essential role of the bacterial cellulose biosynthesis-related gene bcsE, which functions as a cyclic di-GMP-binding protein, in influencing host susceptibility to phage BX-1. …”
