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

Biochemical 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

Blood, 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+

Oscillations Governed by the Incoherent Dynamics in Necroptotic Signaling

Frontiers 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.

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

Nature 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

Cell 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 ...

Self-propelled deformable particle model for keratocyte galvanotaxis [PDF]

Biophys. J. p130-142 January 03, 2023, 2022
During wound healing, fish keratocyte cells undergo galvanotaxis where they follow a wound-induced electric field. In addition to their stereotypical persistent motion, keratocytes can develop circular motion without a field or oscillate around the field direction.

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

Bioengineering, 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.

A model of cell biological signaling predicts a phase transition of signaling and provides mathematical formulae. [PDF]

PLoS ONE, 2014
A biological signal is transmitted by interactions between signaling molecules in the cell. To date, there have been extensive studies regarding signaling pathways using numerical simulation of kinetic equations that are based on equations of continuity ...
