Physiology<br>Ph.D.<br>Cardiovascular disease remains the number one cause or mortally in the western world. Heart failure is the most rapidly growing cardiovascular disease (Hobbs, 2004; Levy, et al., 2002). Heart failure, by definition, is progressive deteriorating function of the heart due to progressive cardiac myocytes loss. Though after decades of endeavor of searching the pathophysiology and treatments for heart failure, it remains highly lethal. Therefore, it is vital to find novel therapies to help treat such chronic disease. Replace the lost cardiomyocyte with new ones could restore

Molecular and Cellular Physiology<br>Ph.D.<br>Pathological cardiac stressors, including persistent hypertension or damage from ischemic heart disease, induce a chronic demand for enhanced contractile performance of the heart. The cytosolic calcium (Ca2+) transient that regulates myocyte contraction must be persistently increased in disease states in order to maintain cardiac output to sustain the metabolic requirements of the body. Associated with this enhanced intracellular Ca2+ ([Ca2+]i) state is pathological cardiac myocyte hypertrophy, which results in large part from the activation of Ca2

The largest Ca2+ store in the cell is the ER where Ca2+ levels approach millimolar levels. The ER regulates cytosolic Ca2+ homeostasis by using Ca2+ binding proteins, the SERCA pump, second messenger Ca2+ release upon IP3 receptor activation, and Ca2+-induced Ca2+ release by ryanodine rec

ZnT-1 expression in the pre-implantation mouse embryo and its effect on calcium influx Pre-implantation embryos develop into 9 stages over the first 5 days post-fertilisation. Calcium influx from the external environment via calcium channels, including the L-type and T-type calcium channels, is critical for embryonic gene activation and cell proliferation. In cardiomyocytes these channels are regulated by the ubiquitously expressed zinc-transporter protein ZnT-1. When plasma membrane bound, ZnT-1 facilitates zinc-efflux.

Nod factor (NF) can induce two separate calcium responses in legume root hairs. Nuclear-associated calcium spiking is central to the symbiosis signalling (Sym) pathway, which is necessary for the activation of genes required for nodule formation and bacterial infection. In addition NF activates a tip-focused calcium influx, which is less-well studied but is thought to be involved in bacterial infection. NF also activates ROS transient production at the tip of root hair cells. In this thesis I used fluorescent probes (Ca2+-sensitive Cameleons YC2.1 and YC3.6 and the ROS-sensitive CM-H2DCFDA dye

It was shown in this thesis, that EPA partially blocked the contraction of aortic smooth muscle cells to the vasoactive agents KCl and noradrenaline.

Abstract (sommario):
A O-glicosilação com N-acetil-glucosamina (O-GlcNAc) é uma modificação pós-translacional altamente dinâmica que modula diversas vias de sinalização. O processo de O-GlcNAc é controlado por duas enzimas: a enzima OGT é responsável por catalisar a adição de N-acetil-glucosamina no grupo hidroxila dos resíduos de serina e treonina, enquanto a OGA catalisa a remoção de O-GlcNAc das proteínas modificadas. Proteínas com importante papel na função vascular são alvo de O-GlcNAc e o aumento da expressão de proteínas modificadas por O-GlcNAc promove aumento da reatividade vascular para estímulos contrát

L'objectif de ce travail a été d'améliorer la protection myocardique au cours des épisodes d'ischémie globale inhérents aux interventions chirurgicales cardiaques. Notre modèle expérimental a été le cœur isolé perfusé de rat, soit travaillant soit isovolumique. Les résultats ont été évalués sur les critères hémodynamiques habituels complétés par les critères biochimiques fournis par RMN du phosphore 31. Dans un premier temps, nous avons cherché à mettre au point une solution cardioplégique ayant pour but principal de limiter la surcharge calcique intracellulaire. A cet effet ont été définis un

Similarly, a slow and sustained [Ca2+]i increase, or a slow but not sustained [Ca2+]i increase was observed after intracellular Ca2+ pump was inhibited by thapsigargin (TG) in t

Abstract (sommario):
The effects of phorbol ester, which activates protein kinase C (PKC), and free cytosolic Ca²+ were studied on their role in process extension in cultured murine oligodendrocytes. Previous studies have shown that PKC activation by phorbol esters greatly enhances process formation in cultured oligodendrocytes (OLG), an important step for myelination. Because of the possible involvement of PKC and Ca²+ in process extension in OLGs, we studied the effect of PKC activation on changes in intracellular free Ca²+ concentration ([Ca²+]i). We found that PKC activation by phorbol esters induced a s

During starvation, autophagosomes form mainly at the endoplasmic reticulum (ER)-mitochondria contact sites. However, how cells timely induce autophagy at these sites are unclear. We aimed to elucidate the roles of ER and mitochondrial calcium-reactive oxygen species (ROS) signaling in autophagosome formation at these sites. We used confocal live-cell imaging to monitor autophagy activity in the absence or presence of calcium and ROS inhibitors. We found that autophagy activity b

Abstract (sommario):
Ca2+ dynamics affect many critical cellular processes. In the bag cell neurons of Aplysia californica, intracellular Ca2+ is elevated during a prolonged period of firing known as the afterdischarge. This consists of a fast and slow phase of firing, which triggers peptide secretion and culminates in egg-laying. The present study examines how Ca2+ influx and release shape neurosecretion and membrane activity. Using capacitance tracking as an index of secretion, a 5 Hz, 1 min train, to mimic the fast phase, induced a clear elevation in the membrane surface area of cultured bag cell neurons. The
