Synergid cell calcium oscillations refine understanding of FERONIA/LORELEI signaling during interspecific hybridization

Plant Reproduction, 2023
Abstract Key message Pollen tubes from closely related species and mutants lacking pollen tube MYB transcription factors are able to initiate FER/LRE-dependent synergid cell calcium oscillations. Abstract Reproductive isolation leads to the evolution of new species; however,

Bi-modal distribution of the second messenger c-di-GMP controls cell fate and asymmetry during the caulobacter cell cycle [PDF]

, 2013
Many bacteria mediate important life-style decisions by varying levels of the second messenger c-di-GMP. Behavioral transitions result from the coordination of complex cellular processes such as motility, surface adherence or the production of virulence ...

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

iScience, 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.

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

iScience, 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.

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

Cell 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 ...

stim2b Knockout Induces Hyperactivity and Susceptibility to Seizures in Zebrafish Larvae

, 2020
In neurons, stromal interaction molecule (STIM) proteins regulate store-operated Ca2+ entry (SOCE) and are involved in calcium signaling pathways. However, STIM activity in neurological diseases is unclear and should be clarified by studies that are ...

Analysis of circadian pattern reveals tissue-specific alternative transcription in leptin signaling pathway

, 2007
*Background* It has been previously reported that most mammalian genes display a circadian oscillation in their baseline expression. Consequently, the phase and amplitude of each component of a signal transduction cascade has downstream ...

Latrunculin A delays anaphase onset in fission yeast by disrupting an ase1-independent pathway controlling mitotic spindle stability [PDF]

, 2008
It has been proposed previously that latrunculin A, an inhibitor of actin polymerization, delays the onset of anaphase by causing spindle misorientation in fission yeast.

Spatiotemporal oscillations of Notch1, Dll1 and NICD are coordinated across the mouse PSM [PDF]

, 2014
During somitogenesis, epithelial somites form from the pre-somitic mesoderm (PSM) in a periodic manner. This periodicity is regulated by a molecular oscillator, known as the 'segmentation clock', that is characterised by an oscillatory pattern of gene ...
