Computational design of a soluble mimic of the outer membrane LPS transport protein LptD suitable for screening of antibiotics

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract Lipopolysaccharides (LPS) are the principal chemical component of the outer leaflet of Gram‐negative bacteria and constitute the first barrier of defense against foreign molecules. Inhibition of LPS transport presents a novel concept for antibiotic discovery, and components of the transport bridge are targets of antimicrobial peptides. LptD, a

Atypical Tetracyclines Promote Longevity and Ferroptotic Neuroprotection via Translation Attenuation

open access: yesAging Cell, Volume 25, Issue 6, June 2026.
Tetracyclines extend lifespan and protect neurons from ferroptosis by attenuating protein synthesis across multiple eukaryotic models through ISR‐dependent or ISR‐independent mechanisms, enabling classification based on their mode of action. ABSTRACT Reducing protein synthesis extends lifespan across taxa, but pharmacological strategies to safely ...

Ischemia‐Induced Post‐Translational Modifications of GLT‐1 Mediate Aberrant Trafficking and Impaired Glutamate Uptake

open access: yesJournal of Neurochemistry, Volume 170, Issue 6, June 2026.
Ischemic insult causes hyper‐glutamatergic signaling and neuronal death. The astrocytic transporter GLT‐1, which clears extracellular glutamate, is internalized and degraded in response to ischemia. We found that lysine‐directed post‐translational modifications (particularly ubiquitination) of the C‐terminal domain drive aberrant trafficking ...

The role of NETosis in breast cancer: mechanistic insights and biomarker potential

open access: yesBreast Cancer Research
Neutrophil extracellular trap formation (NETosis), previously described as an effector host defense mechanism, is more frequently associated with cancer-driven inflammation and tumor development. In the case of breast cancer, NETosis assists with several

Studies on Silkworm Deoxyribonuclease I. Part III

open access: yesJournal of the agricultural chemical society of Japan, 1960
Sp-DNAのS-DNase I消化物のうち約46%は蒸溜水に対して非透析性の所謂“Core”分劃である.本分劃に就いてWyatt(8)の方法によって塩基組成,アデニン:グアニン:シトシン:チミン=29.5:21.5:20.3:28.6 (モル百分率)を求め,又末端燐酸基の定量的除去にボスホモノエステラーゼを用いる事により末端基法によって平均重合度約4.6という値を得,両値から平均分子量約1450を算出した.又S-DNase Iによる分解産物中のモノヌクレオチドが5'-燐酸であるという前報(1)の観察結果を, “Corn”分劃の末端燐酸基の結合位置についても,はぶ毒消化の結果やホスホモノエステラーゼ前処理によるホスホジエステラーゼ感受性の低下から敷衍する事が出来た.欺くてS-DNase ...

Tumor-derived DNA drives cancer-associated anemia by promoting reticulocyte clearance

open access: yesSignal Transduction and Targeted Therapy
Anemia is one of the most prevalent systemic complications in patients with cancer, substantially impairing quality of life and limiting the safe administration of cytoreductive therapies. Despite its clinical significance, the mechanisms by which tumors
