A Signaling Cascade of Nuclear Calcium-CREB-ATF3 …

Synapse-to-nucleus signaling triggered by synaptic NMDA receptors can lead to the buildup of a neuroprotective shield. Nuclear calcium activating the cAMP response element binding protein (CREB) plays a key role in neuroprotection acquired by synaptic activity. Here we show that in mouse hippocampal neurons, the transcription factor Atf3 (activating transcription factor 3) is a direct target

Objectives: To determine how changes in mitochondrial calcium uniporter (MCU) complex (MCUC) function influence mitochondrial dynamics and contribute to PAH’s cancer-like phenotype. Methods: PASMCs were isolated from patients with PAH and healthy control subjects and assessed for expression of MCUC subunits.

Parathyroid hormone controls paracellular Ca2+ transport …

Significance Renal calcium reabsorption is a critical process for maintaining systemic calcium homeostasis. Although the role of parathyroid hormone (PTH) in the regulation of transcellular Ca 2+ reabsorption in distal convoluted tubules is well understood, its potential role in controlling the paracellular Ca 2+ transport in the thick ascending li of Henle (TAL) has not been investigated.
