Receptor-specific Ca2+ oscillation patterns mediated by differential regulation of P2Y purinergic receptors in rat hepatocytes

open access: yesiScience, 2021
Summary: Extracellular agonists linked to inositol-1,4,5-trisphosphate (IP3) formation elicit cytosolic Ca2+ oscillations in many cell types, but despite a common signaling pathway, distinct agonist-specific Ca2+ spike patterns are observed.

Splice variants of DOMINO control Drosophila circadian behavior and pacemaker neuron maintenance. [PDF]

open access: yes, 2019
Circadian clocks control daily rhythms in behavior and physiology. In Drosophila, the small ventral lateral neurons (sLNvs) expressing PIGMENT DISPERSING FACTOR (PDF) are the master pacemaker neurons generating locomotor rhythms.

STIM1- and Orai1-mediated Ca2+ oscillation orchestrates invadopodium formation and melanoma invasion

open access: yesJournal of Cell Biology, 2014
Calcium signaling mediated by STIM1 and Orai1 activates Src to promote invadopodium assembly while simultaneously promoting MT1-MMP recycling to the plasma membrane to promote ECM degradation.

The circadian clock protein Cryptochrome 1 is a direct target and feedback regulator of the Hippo pathway

open access: yesiScience, 2023
Summary: Circadian clock controls daily behavior and physiology. The activity of various signaling pathways affects clock gene expression. Here, we show that the core circadian clock gene CRY1 is a direct target of the Hippo pathway effector YAP.

Genetic disruption of the core circadian clock impairs hippocampus-dependent memory [PDF]

open access: yes, 2014
Perturbing the circadian system by electrolytically lesioning the suprachiasmatic nucleus (SCN) or varying the environmental light:dark schedule impairs memory, suggesting that memory depends on the circadian system.

Collective cell migration of Dictyostelium without cAMP oscillations at multicellular stages

open access: yesCommunications Biology, 2019
In Dictyostelium discoideum, a model organism for the study of collective cell migration, extracellular cyclic adenosine 3’,5’-monophosphate (cAMP) acts as a diffusible chemical guidance cue for cell aggregation, which has been thought to be important in

Mathematical models for somite formation [PDF]

open access: yes, 2007
Somitogenesis is the process of division of the anterior–posterior vertebrate embryonic axis into similar morphological units known as somites. These segments generate the prepattern which guides formation of the vertebrae, ribs and other associated ...

Resonance in the Mouse Ventral Tegmental Area Dopaminergic Network Induced by Regular and Poisson Distributed Optogenetic Stimulation in-vitro

open access: yesFrontiers in Computational Neuroscience, 2020
Neurons in many brain regions exhibit spontaneous, intrinsic rhythmic firing activity. This rhythmic firing activity may determine the way in which these neurons respond to extrinsic synaptic inputs. We hypothesized that neurons should be most responsive

Optogenetic perturbation and bioluminescence imaging to analyze cell-to-cell transfer of oscillatory information.

open access: yesGenes & Development, 2017
Cells communicate with each other to coordinate their gene activities at the population level through signaling pathways. It has been shown that many gene activities are oscillatory and that the frequency and phase of oscillatory gene expression encode ...
