Transcriptional control of the H-NS antagonists LeuO and RcsB-BglJ in Escherichia coli [PDF]

open access: yes, 2012
The bacterial nucleoid-associated protein (NAP) H-NS is involved in the organization and compaction of the bacterial chromatin and acts as a global respressor, mainly of genes that have been acquired by horizontal gene transfer and that are related to ...

Endocytic Programming via Porous Silicon Nanoparticles Enhances TLR4 Nanoagonist Potency for Macrophage‐Mediated Immunotherapy

open access: yesAdvanced Functional Materials, EarlyView.
Porous silicon nanoparticles (PSiNPs) reprogram macrophage endocytosis of manganese@albumin‐based TLR4 nanoagonists, driving TRIF‐biased TLR4 signaling, eliciting robust proinflammatory responses, and potentiating macrophage‐mediated immunotherapeutic effects against NSCLC.

FANCM promotes PARP inhibitor resistance by minimizing ssDNA gap formation and counteracting resection inhibition

open access: yesCell Reports
Summary: Poly(ADP-ribose) polymerase inhibitors (PARPis) exhibit remarkable anticancer activity in tumors with homologous recombination (HR) gene mutations. However, the role of other DNA repair proteins in PARPi-induced lethality remains elusive.

Nanobody‐Decorated Lipid Nanoparticles for Enhanced mRNA Delivery to Tumors In Vivo

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a targeted mRNA‐LNP platform engineered with anti‐PSMA nanobodies for prostate cancer therapy. Using different in vivo models, the authors demonstrate selective uptake and mRNA delivery in PSMA+ cancer cells. However, while targeting is enhanced, mRNA delivery efficacy is limited by tissue penetration, tumor necrosis, and immune ...
