Resumen
In many cells, including hepatocytes, receptors coupled to phosphoinositide hydrolysis stimulate oscillatory changes in cytosolic [Ca<SUP>2+</SUP>] ([Ca<SUP>2+</SUP>]<SUB>i</SUB>). I have used two methods to examine the means whereby such [Ca<SUP>2+</SUP>]<SUB>i</SUB> transients are linked to the stimulation of glycogenolysis. By perifusing rat hepatocytes prelabelled with [<SUP>3</SUP>H]-glucose, I showed that phenylephrine increases the rate of [<SUP>3</SUP>H]-glucose release by 2-3 fold, and confirmed this effect using a colorimetric assay for glucose.

Resumen
Bacteria have evolved ways to sense and respond to changes in their population density through quorum sensing (QS) systems, and to adapt to changes in the extracellular environment through two component systems (TCS). In Pseudomonas aeruginosa, QS and the GacS/GacA TCS are global regulatory systems that modulate the expression of virulence genes at the transcriptional and post-transcriptional level, respectively. Although in P. aeruginosa the QS network has been extensively characterized, the way the Gac/Rsm global regulatory system is regulated is still unclear. The study of QS and Gac/Rsm ne

Resumen
Ca2+ signaling is essential for a wide variety of cellular activities, ranging from short term activities, such as synaptic and muscle contraction, to long term processes, such as proliferation and differentiation. Store-operated Ca2+ entry (SOCE), an important Ca2+ influx pathway in non-excitable cells, well coordinates Ca2+ release from ER and Ca2+ influx through plasma membrane. STIM1 and Orai1, serving as ER Ca2+ sensor and pore forming subunit, respectively, are the two essential components of SOCE machinery. In addition to activate Orai1 channel, studies have shown that STIM1 regulates o

Resumen
Parathyroid hormone (PTH) secretion maintains free-ionised extracellular calcium (Ca2+o) homeostasis under the control of the calcium-sensing receptor (CaR). In humans and dogs, blood acidosis and alkalosis is associated with increased or suppressed PTH secretion respectively. Furthermore, large (1.0 pH unit) changes in extracellular pH (pHo) alter Ca2+o sensitivity of the CaR in CaR-transfected HEK-293 cells (CaR-HEK). Indeed, it has been found in this laboratory that even pathophysiological acidosis (pH 7.2) renders CaR less sensitive to Ca2+o while pathophysiological alkalosis (pH 7.6) incr

Signalling processes regulate various aspects of living cells via modulation of protein activity. The interactions between the signalling proteins can occur at single or multiple sites. Although single site protein interactions are relatively easy to understand, these rarely occur in living systems. It is therefore important to investigate multisite interactions. Despite the recent progress in experimental studies, the underlying molecular mechanisms and molecular functions of the multisite interactions are still not clear and therefore require systems approaches for deeper understanding, for

Presenilin (PS) is the catalytic subunit of the gamma-secretase which is responsible for the cleavage of amyloid precursor protein to form beta amyloid (Aβ). Mutations in PS cause familial Alzheimer’s disease (FAD) by increasing the Aβ plaques formation in the brain and thereby induce neurodegeneration. Apart from this, FAD-linked PS mutations have been demonstrated to disrupt cellular calcium (Ca2+) homeostasis.

Presenilin-1 (PS1) mutations caused by the PSEN1 gene mutations are the major cause of early onset familial Alzheimer’s disease (EOFAD). Two Chinesespecific EOFAD related PS1 mutations, V97L and A136G, have been found. Studies suggested that V97L mutation lead to the overexpression of Aβ42 and tau hyperphosphorylation, which are the major hallmarks of Alzheimer’s disease (AD), while properties of A136G were unclear.
