Stem Cell Differentiation Disperses Transcriptional Clusters via a Conserved Surface‐Condensate Trajectory

open access: yesAdvanced Science, EarlyView.
Stem cell differentiation follows a conserved surface condensate trajectory: H3K27ac super enhancers nucleate large RNA polymerase II clusters that grow and unfold before transcriptional activity disperses them. This work reveals how biophysical forces at enhancer surfaces dynamically build and dismantle stem cell transcription hubs, reshaping cell ...

The histone chaperones Vps75 and Nap1 form ring-like, tetrameric structures in solution [PDF]

open access: yes, 2013
NAP-1 fold histone chaperones play an important role in escorting histones to and from sites of nucleosome assembly and disassembly. The two NAP-1 fold histone chaperones in budding yeast, Vps75 and Nap1, have previously been crystalized in a ...

The p97 segregase cofactor Ubxn7 facilitates replisome disassembly during S-phase [PDF]

open access: yes, 2022
Complex cellular processes are driven by the regulated assembly and disassembly of large multiprotein complexes. While we are beginning to understand the molecular mechanism for assembly of the eukaryotic DNA replication machinery (replisome), we still ...

Nigericin‐Triggered Phosphodynamics in Inflammasome Formation and Pyroptosis

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Innate immune signaling relies heavily on phosphorylation cascades to mount effective immune responses. Although traditional innate immune signaling cascades following TLR4 stimulation have been investigated through a temporally quantitative phosphoproteomic lens, far fewer studies have applied these methods to distinct signaling following the

Compositional and structural analysis of selected chromosomal domains from Saccharomyces cerevisiae

open access: yes, 2012
In eukaryotic genomes, chromatin is the template of all nuclear processes including transcription, recombination and replication. Besides the wrapping of DNA in nucleosome core particles, eukaryotic chromatin is associated, interpreted and modified by ...

Involvement of the lamin rod domain in heterotypic lamin interactions important for nuclear organization [PDF]

open access: yes, 2001
The nuclear lamina is a meshwork of intermediate-type filament proteins (lamins) that lines the inner nuclear membrane. The lamina is proposed to be an important determinant of nuclear structure, but there has been little direct testing of this idea.

Redox‐responsive dual‐drug nanomedicine integrating cisplatin and trypsin for synergistic reversal of tumor chemoresistance

open access: yesSmart Molecules, EarlyView.
This study presents a novel glutathione‐activatable prodrug nanomedicine (cRGD‐PEG‐PGlu‐NP (ssTrypsin & CDDP)) that co‐encapsulates cisplatin and a masked protease to combat cisplatin resistance. The dual‐drug system selectively targets resistant tumor cells, enhancing the efficacy of cisplatin while minimizing systemic toxicity.

Cuproptosis Inducers in Cancer Therapy: State of the Art and Challenges

open access: yesThe Chemical Record, EarlyView.
Cuproptosis is emerging as a distinct copper‐dependent cell death pathway, highlighting copper as a potential metabolic vulnerability in cancer. This review examines how coordination chemistry, redox regulation, and nanomaterial design shape Cu reactivity and therapeutic outcomes.
