Chondroitinase ABC Promotes Axon Regeneration and Reduces Retrograde Apoptosis Signaling in Lamprey
Frontiers in Cell and Developmental Biology, 2021 Paralysis following spinal cord injury (SCI) is due to failure of axonal regeneration. It is believed that axon growth is inhibited by the presence of several types of inhibitory molecules in central nervous system (CNS), including the chondroitin ...

Analysis of chlorophyll fluorescence reveals stage specific patterns of chloroplast-containing cells during Arabidopsis embryogenesis [PDF]
, 2010 http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0716-97602010000100012&lng=es&nrm=isoThe basic body plan of a plant is established early in embryogenesis when cells differentiate, giving rise to the apical and basal regions of the embryo.

Spatial control of Draper receptor signaling initiates apoptotic cell engulfment. [PDF]
, 2017 The engulfment of apoptotic cells is essential for tissue homeostasis and recovering from damage. Engulfment is mediated by receptors that recognize ligands exposed on apoptotic cells such as phosphatidylserine (PS).

From retrograde signaling to flowering time [PDF]
Plant Signaling & Behavior, 2015 Plant's transition from vegetative to reproductive phase is balanced by intricate cascade of genes regulated by both endogenous and environmental inputs. Stress causes suppression of vegetative growth and acceleration of flowering as an emergency response for preservation of the species. Recently, we determined that expression levels of a transcription

Self-repair in a Bidirectionally Coupled Astrocyte-Neuron (AN) System based on Retrograde Signaling
Frontiers in Computational Neuroscience, 2012 In this paper we demonstrate that retrograde signaling via astrocytes may underpin self-repair in the brain. Faults manifest themselves in silent or near silent neurons caused by low transmission probability synapses; the enhancement of the transmission ...

Chloroplast Signaling: Retrograde Regulation Revelations [PDF]
Current Biology, 2011 Developing chloroplasts are able to communicate their status to the nucleus and regulate expression of genes whose products are needed for photosynthesis. Heme is revealed to be a signaling molecule for this retrograde communication.

Chloroplasts are central players in sugar-induced leaf growth [PDF]
, 2016 Leaves are the plant's powerhouses, providing energy for all organs through sugar production during photosynthesis. However, sugars serve not only as a metabolic energy source for sink tissues but also as signaling molecules, affecting gene expression ...

Mitochondrial retrograde signaling regulates neuronal function [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance Mitochondrial retrograde signaling is an ancient mechanism defined as the cellular response to changes in the functional state of mitochondria. We find that in the Drosophila nervous system, mitochondrial dysfunction activates a retrograde response controlling hundreds of nuclear genes.
