Histamine-H1-receptor-mediated phosphoinositide hydrolysis, Ca2+ signalling and membrane-potential oscillations in human HeLa carcinoma cells [PDF]

open access: greenBiochemical Journal, 1990
In human HeLa carcinoma cells, histamine causes a dose-dependent formation of inositol phosphates, production of diacylglycerol and a transient rise in intracellular [Ca2+]. These responses are completely blocked by the H1-receptor antagonist pyrilamine.

Autonomous Ca2+ Oscillations Reflect Oncogenic BCR-Signaling in Multiple B-Cell Malignancies and Are Essential for Survival and Proliferation

open access: bronzeBlood, 2018
Abstract Background: Nuclear factor of activated T cells (NFAT) factors regulate activation and Ca2+ signaling in B-cells. Store-operated Ca2+ entry (SOCE) is regulated by Orai1 and Stim1 and upstream of NFAT. We previously reported on the observation of autonomous oscillatory Ca2+ signal activity in BCR-ABL1-driven B-ALL. Autonomous Ca2+

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.

Dynamic intracellular mechanical cues facilitate collective signaling responses

open access: yesiScience, 2021
Summary: Collective behavior emerges in diverse life machineries, e.g., the immune responses to dynamic stimulations. The essential questions that arise here are that whether and how cells in vivo collectively respond to stimulation frequencies higher ...

Jag1-Notch cis-interaction determines cell fate segregation in pancreatic development

open access: yesNature Communications, 2023
Notch signaling is crucial for pancreatic cell fate choice. With mathematical modeling and experiments, Xu et al. provides new insights into how different Notch ligands and Hes1 oscillation guide the spatial-temporal dynamics of cell differentiation.

Loss of thyroid gland circadian PER2 rhythmicity in aged mice and its potential association with thyroid cancer development

open access: yesCell Death and Disease, 2022
Molecular clocks operate in peripheral tissues, including endocrine glands, and play important regulatory roles in this context. However, potential age-related changes in the expression rhythmicity of clock genes and the effects of these changes on the ...

Oscillatory ERK Signaling and Morphology Determine Heterogeneity of Breast Cancer Cell Chemotaxis via MEK-ERK and p38-MAPK Signaling Pathways

open access: yesBioengineering, 2023
Chemotaxis, regulated by oscillatory signals, drives critical processes in cancer metastasis. Crucial chemoattractant molecules in breast cancer, CXCL12 and EGF, drive the activation of ERK and Akt.
