The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

HIV-2 infection as a comparative lens for functional HIV-1 remission

open access: yesFrontiers in Immunology
Four decades into the HIV pandemic, HIV-2 infection remains an underutilized comparative resource for HIV-1 cure research. HIV-2 is associated with lower plasma viral loads, slower CD4+ T-cell decline, and delayed disease progression in many individuals.

Curaxin CBL0100 Blocks HIV-1 Replication and Reactivation through Inhibition of Viral Transcriptional Elongation

open access: yesFrontiers in Microbiology, 2017
Despite combination antiretroviral therapy (cART), acquired immunodeficiency syndrome (AIDS), predominantly caused by the human immunodeficiency virus type 1 (HIV-1), remains incurable.

Efficacy and Safety of Two-Level Brachial Plexus Block at Locking Intramedullary Shoulder Osteosynthesis

open access: yesVestnik travmatologii i ortopedii imeni N.N. Priorova, 2016
Results of the comparative study of the efficacy and safety of one- and two-level brachial plexus block (BPB) at locking intramedullary shoulder osteosynthesis are presented. Fifty five patients (mean age 43.4±3.2 years) with humeral diaphysis fracture were operated on.

Extracellular vesicle lipidomics liquid biopsy reveals systemic and tumor microenvironment metabolic reprogramming in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.

Analysis on Locking Mechanism Performance of SCM Running Tool for Subsea Horizontal X-tree

open access: yesShiyou jixie, 2016
The locking element is the most significant part of the whole SCMRT.In the theoretical analysis,locking angle,unlocking angle and cone angle are mainly considered for the lock block.Self-locking would not occur when the lock angle α is larger than 8.5 ...

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

open access: yesMolecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.
