Asymmetric protonation of EmrE [PDF]

, 2015
The small multidrug resistance transporter EmrE is a homodimer that uses energy provided by the proton motive force to drive the efflux of drug substrates. The pKa values of its “active-site” residues—glutamate 14 (Glu14) from each subunit—must be poised

Minimizing the ratio of ionizable lipid in lipid nanoparticles for in vivo base editing. [PDF]

Natl Sci Rev
ABSTRACT Lipid nanoparticles (LNPs) have gained clinical approval as carriers for both siRNA and mRNA. Among the crucial components of LNPs, ionizable lipids play a pivotal role in determining the efficiency of RNA delivery. In this study, we synthesized a series of ionizable lipids, denoted as HTO, with a higher count of hydroxyl groups

Molecular dynamics as an approach to study prion protein misfolding and the effect of pathogenic mutations [PDF]

, 2011
Computer simulation of protein dynamics offers unique high-resolution information that complements experiment. Using experimentally derived structures of the natively folded prion protein (PrP), physically realistic dynamics and conformational changes ...

Atherogenic lipid fractions are related to ionized magnesium status [PDF]

The American Journal of Clinical Nutrition, 1998
The plasma concentration of ionized magnesium (iMg++), the serum total magnesium concentration (tMg), and lipoprotein status were assessed in 29 elderly men with impaired insulin sensitivity but who were otherwise healthy and not receiving antidiabetic pharmacologic treatment.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Biotechnology: Overcoming biological barriers to nucleic acid delivery using lipid nanoparticles.

PLoS Biology, 2023
The promise of therapeutic nucleic acids has long been tempered by difficulty in overcoming biological barriers to their delivery. The past two decades have seen the development of ionizable lipid nanoparticles as a vehicle for nucleic acid delivery and ...

Current and evolving approaches for improving the oral permeability of BCS Class III or analogous molecules [PDF]

, 2016
The Biopharmaceutics Classification System (BCS) classifies pharmaceutical compounds based on their aqueous solubility and intestinal permeability. The BCS Class III compounds are hydrophilic molecules (high aqueous solubility) with low permeability ...

ATP13A2 is involved in intracellular polyamine transport in lung epithelial cells

FEBS Open Bio, EarlyView.
Spermidine transport in lung epithelial cells involves the polyamine transporter ATP13A2. Cell proliferation is associated with the upregulation of ATP13A2. Polyamines are present in all living cells and are implicated in various crucial cellular processes such as proliferation, apoptosis and autophagy.
