Clock-modified mesenchymal stromal cells therapy rescues molecular circadian oscillation and age-related bone loss via miR142-3p/Bmal1/YAP signaling axis [PDF]

open access: goldCell Death Discovery, 2022
Age-related bone loss and disease strongly affect the quality of life of the elderly population. Cellular circadian rhythms have been reported to regulate bone aging, and micro RNAs (miRNAs) play crucial posttranscriptional regulatory roles in the ...

PLCγ2 controls neutrophil-like cell sensitivity through calcium oscillation and gates chemoattractant concentration range for chemotaxis [PDF]

open access: yesFrontiers in Immunology
The relationship between calcium oscillation and cell sensitivity is poorly understood. Calcium oscillation can occur spontaneously or be triggered upon receptor-ligand binding.

An agent-based model of metabolic signaling oscillations in Bacillus subtilis biofilms. [PDF]

open access: yesPLoS Computational Biology
Microbes of nearly every species can form biofilms, communities of cells bound together by a self-produced matrix. It is not understood how variation at the cellular level impacts putatively beneficial, colony-level behaviors, such as cell-to-cell ...

Calcium oscillations in mesenchymal stem cells, a control on cell cycle progression to influence cell fate towards proliferation or differentiation? [PDF]

open access: yesStem Cell Research & Therapy
Background Under regular culture conditions, mesenchymal stem cells (MSCs) exhibit cytosolic calcium concentration oscillations (Ca2+ oscillations), that change, especially in frequency, after the differentiation of the MSCs.

Origins of Ultrasensitivity and Complex Signaling Dynamics of Cellular Hydrogen Peroxide and Peroxiredoxin [PDF]

open access: yesAntioxidants
Hydrogen peroxide (H2O2) plays a crucial role in cell signaling in response to physiological and environmental perturbations. H2O2 can oxidize typical 2-Cys peroxiredoxin (PRX) first into a sulfenic acid, which resolves into a disulfide that can be ...

Cholesterol-induced robust Ca oscillation in astrocytes required for survival and lipid droplet formation in high-cholesterol condition

open access: yesiScience, 2022
Summary: Cholesterol, one of the major cell membrane components, stabilizes membrane fluidity and regulates signal transduction. Beside its canonical roles, cholesterol has been reported to directly activate signaling pathways such as hedgehog (Hh).

Oscillations Governed by the Incoherent Dynamics in Necroptotic Signaling

open access: yesFrontiers in Physics, 2021
Emerging evidences have suggested that oscillation is important for the induction of cell death. However, whether and how oscillation behavior is involved and required for necroptosis remain elusive.
