Mechanistic Insights Into Recurrent Implantation Failure: The Lactate–H3K18la–SLC7A11 Axis Explored via Endometrial Organoid and Blastoid–Endometrial Cell Implantation Models

open access: yesCell Proliferation, EarlyView.
Clinical samples first revealed impaired lactate synthesis in RIF patients. Subsequently, using endometrial organoids and a blastoid‐endometrial cell implantation model, we demonstrated that lactate enhances endometrial receptivity via H3K18la‐mediated SLC7A11 activation.

Rhizobial motility preference in root colonization of Medicago truncatula

open access: yesNew Phytologist, EarlyView.
Summary Tunnel‐like infection thread (IT) structures support root colonization by symbiotic nitrogen‐fixing rhizobia bacteria in most legume species. These tip‐grown structures are key to directing rhizobia from root hairs to developing nodules, where they are hosted to fix nitrogen.

Analysis of in-vivo LacR-mediated gene repression based on the mechanics of DNA looping. [PDF]

open access: yesPLoS ONE, 2006
Interactions of E. coli lac repressor (LacR) with a pair of operator sites on the same DNA molecule can lead to the formation of looped nucleoprotein complexes both in vitro and in vivo.

Metabolite-dependent regulation of gene expression in trypanosoma brucei [PDF]

open access: yes, 2013
Mechanisms regulating gene expression in trypanosomatid protozoa differ significantly from those in other eukaryotes. Transcription of the genome appears to be more or less constitutive with the polyadenylation and trans-splicing of large polycistronic ...

Coupling Nitrogenous Organic Wastewater Treatment and Biorefinery via N‐Cycling Bacterium

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
The vast reservoir of nitrogenous organic pollutants in industrial wastewaters can serve as untapped carbon‐nitrogen resources. This study employs the newly discovered Paracoccus sp. ZQW‐1 as a versatile chassis to simultaneously achieve N‐methylpyrrolidone (NMP) wastewater depuration and polyhydroxybutyrate (PHB) synthesis.

Marginal Stability of the YB1 Cold‐Shock Domain in Cells Enables Binding of Multiple Nucleic Acids

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
This study suggests that the marginal stability of the YB1 Cold‐Shock Domain (CSDex) allows for a balance between multifunctionality and conformational changes under physiological conditions. This balance is driven by the dynamic equilibrium between the unfolded ensemble (UE) and the native ensemble (NE) of CSDex (PDB:6LMR).

Network Topology as a Driver of Bistability in the lac Operon

open access: yes, 2008
The lac operon in Escherichia coli has been studied extensively and is one of the earliest gene systems found to undergo both positive and negative control. The lac operon is known to exhibit bistability, in the sense that the operon is either induced or

DNA Sampling: a method for probing protein binding at specific loci on bacterial chromosomes [PDF]

open access: yes, 2009
We describe a protocol, DNA sampling, for the rapid isolation of specific segments of DNA, together with bound proteins, from Escherichia coli K-12. The DNA to be sampled is generated as a discrete fragment within cells by the yeast I-SceI meganuclease ...

Obestatin Treatment Counteracts Muscle Wasting by Reactivation of Autophagy in Duchenne Muscular Dystrophy

open access: yesMedComm, Volume 7, Issue 1, January 2026.
Obestatin signaling reactivates autophagy by NEDD4‐L activation under DMD conditions. Tyrosine switch on NEDD4‐L activates autoubiquitination that serves as a scaffold to recruit USP10 to form a deubiquitination complex, which stabilizes VPS34 to promote autophagy by activation of the Beclin1 complex. In parallel, NEDD4‐L favors AMPK exposure to CaMKKß

Visualization of C. elegans transgenic arrays by GFP

open access: yesBMC Genetics, 2006
Background Targeting the green fluorescent protein (GFP) via the E. coli lac repressor (LacI) to a specific DNA sequence, the lac operator (lacO), allows visualization of chromosomes in yeast and mammalian cells. In principle this method of visualization
