A Doxorubicin‐Loaded Liposomes Baghdadite System for Localized Osteosarcoma Therapy and Bone Regeneration

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study presents a multifunctional Baghdadite ceramic implant integrating doxorubicin‐loaded liposomes via ion‐assisted plasma polymer coating for localized osteosarcoma therapy. The platform enables drug retention, sustained release, tumor cell inhibition, osteoconductivity, and antibacterial activity, offering a mechanically robust strategy for ...

Regulation of reactive oxygen species during plant immunity through phosphorylation and ubiquitination of RBOHD. [PDF]

open access: yes, 2020
Production of reactive oxygen species (ROS) is critical for successful activation of immune responses against pathogen infection. The plant NADPH oxidase RBOHD is a primary player in ROS production during innate immunity. However, how RBOHD is negatively

Histamine stimulates the proliferation of small and large cholangiocytes by activation of both IP3/Ca2+ and cAMP-dependent signaling mechanisms [PDF]

open access: yes, 2012
Although large cholangiocytes exert their functions by activation of cyclic adenosine 3',5'-monophosphate (cAMP), Ca(2+)-dependent signaling regulates the function of small cholangiocytes. Histamine interacts with four receptors, H1-H4HRs.

Segmental helical motions and dynamical asymmetry modulate histidine kinase autophosphorylation.

open access: yesPLoS Biology, 2014
Histidine kinases (HKs) are dimeric receptors that participate in most adaptive responses to environmental changes in prokaryotes. Although it is well established that stimulus perception triggers autophosphorylation in many HKs, little is known on how ...

Tissue‐Specific and Spatially Dependent Metabolic Signatures Perturbed by Injury in Male and Female Mice

open access: yesArthritis &Rheumatology, EarlyView.
Objective Osteoarthritis, the leading cause of disability worldwide, disproportionately affects women, yet sex remains an overlooked determinant. This disparity stems from sex‐specific differences in injury susceptibility—a major risk factor for disease.

ARR1 and AHP interactions in the multi-step phosphorelay system

open access: yesFrontiers in Plant Science
Plants use multi-step phosphorelay (MSP) systems in response to exogenous and endogenous stimuli. Cytokinin and ethylene are among the factors that engage MSP signaling cascades but examples independent of phytohormones also exist.

Enhanced strategies for cuproptosis‐like death in bacterial infection treatment

open access: yesBMEMat, EarlyView.
This review summarizes and examines the molecular mechanisms underlying cuproptosis‐like death. Furthermore, multi‐strategy efficacy enhancement and potential enhancement approaches are analyzed. Abstract Copper, a classical antibacterial metal, has long been of interest and widely used in medical and public health applications.

Optimization of CEST MRI Reporter Protein Design Using Cation‐Pi Networks

open access: yesChemistry – A European Journal, EarlyView.
A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...

ProTides for Antiviral Activity Beyond Liver Cells

open access: yesChemistry – A European Journal, EarlyView.
A strategy for obtaining prodrugs of antiviral nucleotides with broad tissue activity is presented that relies on cycloalkyl or cycloalkylalkyl esters, improving uptake and esterase cleavage, and producing nanomolar inhibitors in kidney, colon, and lung cells.

The extracytoplasmic linker peptide of the sensor protein SaeS tunes the kinase activity required for staphylococcal virulence in response to host signals.

open access: yesPLoS Pathogens, 2015
Bacterial pathogens often employ two-component systems (TCSs), typically consisting of a sensor kinase and a response regulator, to control expression of a set of virulence genes in response to changing host environments.
