Positional information readout in $Ca^{2+}$ signaling [PDF]
Living cells respond to spatial signals. Signal transmission to the cell interior often involves the release of second messengers like $Ca^{2+}$ . They will eventually trigger a physiological response by activating kinases that in turn activate target proteins through phosphorylation. Here, we investigate theoretically how positional information can be

Estimation of kinetic rates of MAP kinase activation from experimental data [PDF]
Mathematical model is an important tool in systems biology to study the dynamics of biological systems inside the cell. One of the significant challenges in systems biology is the lack of kinetic rates that should be measured in experiments or estimated ...

ERK-1 MAP kinase prevents TNF-induced apoptosis through bad phosphorylation and inhibition of bax translocation in HeLa cells [PDF]
Extracellular signal-regulated kinase (ERK) 1/2 signaling is involved in tumor cell survival through the regulation of Bcl-2 family members. To explore this further and to demonstrate the central role of the mitochondria in the ERK1/2 pathway we used the

Surveillance-activated defenses block the ROS-induced mitochondrial unfolded protein response. [PDF]
Disturbance of cellular functions results in the activation of stress-signaling pathways that aim at restoring homeostasis. We performed a genome-wide screen to identify components of the signal transduction of the mitochondrial unfolded protein response

praja2 regulates KSR1 stability and mitogenic signaling [PDF]
The kinase suppressor of Ras 1 (KSR1) has a fundamental role in mitogenic signaling by scaffolding components of the Ras/MAP kinase pathway. In response to Ras activation, KSR1 assembles a tripartite kinase complex that optimally transfers signals ...

Analysis of FGF-dependent and FGF-independent pathways in otic placode induction. [PDF]
The inner ear develops from a patch of thickened cranial ectoderm adjacent to the hindbrain called the otic placode. Studies in a number of vertebrate species suggest that the initial steps in induction of the otic placode are regulated by members of the

Extracellular signal-regulated kinase 5 promotes acute cellular and systemic inflammation. [PDF]
Inflammatory critical illness is a syndrome that is characterized by acute inflammation and organ injury, and it is triggered by infections and noninfectious tissue injury, both of which activate innate immune receptors and pathways.

Effects of keratin filaments on ERK signaling during Fas-induced death of cervical cancer (HeLa) cells [PDF]
Survival of cancer cells is influenced by a variety of factors, including physical elements such as keratin filaments. We know HeLa cells containing or lacking keratin 8/18 intermediate filaments (K+ and K- cells, respectively) are more sensitive to the ...
