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>).

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.

Abstract:
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).

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

Abstract:
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

Abstract:
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
