Any process that modulates the frequency, rate or extent of karyogamy, the creation of a single nucleus from multiple nuclei as a result of membrane fusion.

Any process that stops, prevents, or reduces the frequency, rate or extent of signal transduction mediated by the stress-activated MAPK cascade.

Any process that stops, prevents, or reduces the frequency, rate or extent of DNA endoreduplication.

Any process that modulates the frequency, rate or extent of DNA endoreduplication.

Any process that activates or increases the frequency, rate or extent of DNA endoreduplication.

The process in which amyloid-beta is removed from extracellular brain regions by cell surface receptor-mediated endocytosis, followed by intracellular degradation.

Cell-cell signaling that mediates the transfer of information from a neuron to a glial cell. This signalling has been shown to be mediated by various molecules released by different types of neurons, e.g. glutamate, gamma-amino butyric acid (GABA), noradrenaline, acetylcholine, dopamine and adenosine.

Cell-cell signaling that mediates the transfer of information from a glial cell to a neuron. This signaling has been shown to be mediated by various molecules, depending on which glial cells release them, and in which tissues the signalling occurs, e.g. microglial cell-derived nerve growth factor (NGF) in the retina, or microglial cell-derived superoxide ions in the cerebellum.

A protein complex that links the endoplasmic reticulum with mitochondria and may have a role in promoting exchange of calcium and phospholipids between the two organelles.

Catalysis of the reaction: L-arabitol + NADP+ = L-arabinose + NADPH + H+.

Catalysis of the reaction: D-xylitol + NADP+ = D-xylose + NADPH + H+.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a synapse between a multiple synapse bouton and two or more dendritic spines protruding either from a single dendrite or from multiple dendrites.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a synapse between a multiple synapse bouton and one or more dendritic spines.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an insulin stimulus. Insulin is a polypeptide hormone produced by the islets of Langerhans of the pancreas in mammals, and by the homologous organs of other organisms.
