Genome‐wide Identification and expression analysis of TOR signaling pathway components in apple in response to low nitrogen

open access: yesThe Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Target of rapamycin (TOR) is an evolutionarily conserved serine/threonine kinase that plays a central role in regulating biological growth, development, and stress responses in eukaryotes. However, the TOR signaling pathway has not been thoroughly studied in apple (Malus domestica).

Modulation of intramolecular interactions in superhelical DNA by curved sequences: a Monte Carlo simulation study [PDF]

open access: yes, 1995
A Monte Carlo model for the generation of superhelical DNA structures at thermodynamic equilibrium (Klenin et al., 1991; Vologodskii et al., 1992) was modified to account for the presence of local curvature.

Conformational change-induced repeat domain expansion regulates Rap phosphatase quorum-sensing signal receptors. [PDF]

open access: yesPLoS Biology, 2013
The large family of Gram-positive quorum-sensing receptors known as the RNPP proteins consists of receptors homologous to the Rap, NprR, PlcR, and PrgX proteins that are regulated by imported oligopeptide autoinducers.

Coumarin‐Augmented Thiazole Hybrids as Dual Anticancer and Antibacterial Agents

open access: yesChemical Biology &Drug Design, Volume 107, Issue 2, February 2026.
Compound 13, a coumarin‐thiazole hybrid, is shown engaging the ATP‐binding site of S. aureus GyrB through a novel hydrogen bond with residue SER129. The molecule exhibits dual antibacterial and anticancer activity, supporting its potential as a dual‐target topoisomerase inhibitor.

In silico Analysis of CHD4 Mutations Reveals Domain‐Specific Impacts on Cardiovascular Disorders Among Patients With Rare Diseases

open access: yesHuman Mutation, Volume 2026, Issue 1, 2026.
Chromodomain‐helicase‐DNA‐binding protein 4 (CHD4) is a critical ATP‐dependent chromatin remodeler that plays fundamental roles in transcriptional repression, DNA damage repair, and lineage specification, making it indispensable for cardiovascular development and function.

Selective binding of specific mouse genomic DNA fragments by mouse vimentin filaments in vitro [PDF]

open access: yes, 1996
Mouse vimentin intermediate filaments (IFs) reconstituted in vitro were analyzed for their capacity to select certain DNA sequences from a mixture of about 500−bp−long fragments of total mouse genomic DNA.

Cytotoxicity of psammaplin A from a two-sponge association may correlate with the inhibition of DNA replication

open access: yesBMC Cancer, 2004
Background SV40 DNA replication system is a very useful tool to understand the mechanism of replication, which is a tightly regulated process. Many environmental and cellular factors can induce cell cycle arrest or apoptosis by inhibiting DNA replication.

Ergostanes and Cytochalasin From the Fruiting Bodies of Xylaria longipes Nitschke and Their Cytotoxicity Evaluation

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
Four ergostanes—ergosta‐7,22,24(28)‐trien‐3β‐ol (1), ergosta‐7,24(28)‐dien‐3‐one (2), ergosta‐7,22,24(28)‐trien‐3‐one (3), and ergosta‐4,6,8(14),22‐tetraen‐3‐one (4)—and one cytochalasin, zygosporin D (5), were isolated from Xylaria longipes. Two compounds, 2 and 3, are novel but have a similar structure to Compound (1), except for the keto group at ...
