BACKGROUND Increased platelet aggregation is implicated in the pathogenesis of ischemic stroke and anti-platelet strategy may contribute to its therapy. Panaxatriol saponin (PTS), the main components extracted from Panax notoginseng, has been shown to be efficacious in the prevention and treatment of ischemic stroke in China. The aim of this study is to determine the anti-platelet activity and ...

Plasmodium chabaudi malaria parasite organelles are major elements for ion homeostasis and cellular signaling and also target for antimalarial drugs. By using confocal imaging of intraerythrocytic parasites we demonstrated that the dye acridine orange (AO) is accumulated into P. chabaudi subcellular compartments. The AO could be released from the parasite organelles by collapsing the pH gradien...

We have demonstrated previously cell surface receptors for gastrointestinal peptides on 10 human colon cancer cell lines. Because most of the cells studied bind muscarinic cholinergic agonists, we undertook the determination of the cholinergic receptor subtype expressed by human colon cancer cells, as well as the biological function of these receptors, and more specifically, the effect on cell ...

This article contains results of analyses of angiotensin II receptors expression in human adipose tissue and stem/stromal cells isolated from adipose tissue. We also provide here data regarding the effect of angiotensin II on intracellular calcium mobilization in adipose tissue derived stem/stromal cells (ADSCs). Discussion of the data can be found in (Sysoeva et al., 2017) [1].

A recent study shows that sphingosine kinase and its lipid product have an essential signalling function; they act in the mobilization of calcium ions in antigen-stimulated mast cells. This finding may have relevance to signalling in other cells of the immune system.

high-dose chemotherapy and autologous stem cell transplantation (sct) have become an effective care for many patients with hematological malignancies. harvesting the stem cells is one the most important parts of sct. the two most commonly used mobilization regimens are the use of granulocyte colony-stimulating factor (g-csf) or g-csf plus chemotherapy. however, about 10-30% of patients are unab...

peripheral blood stem cell transplantation (pbsct) is an effective treatment for hematological malignancies. mobilization of peripheral blood progenitor cells performs in different ways among transplantation centers. forceful mobilization schedules are comprised of growth factor alone, chemotherapy along with growth factor and also, a newly combination of novel agent such as plerixafor with any...

Purinergic receptor expression and involvement in steroidogenesis were examined in NCI-H295R (H295R), a human adrenal cortex cell line which expresses all the key enzymes necessary for steroidogenesis. mRNA/protein for multiple P1 (A(2A) and A(2B)), P2X (P2X₅ and P2X₇), and P2Y (P2Y₁, P2Y₂, P2Y₆, P2Y₁₂, P2Y₁₃, and P2Y₁₄) purinergic receptors were detected in H295R. 2MeS-ATP (10-1000 µM), a P2Y₁...

It is known that expression of endothelin-1 (ET-1) increases in the epidermis after UVB irradiation, and that this plays an important role during the induction of pigmentation both as a mitogen and as a melanogen for normal human melanocytes (NHMC). When ET-1 acts on NHMC via the endothelin B receptor (ET(B)R) on their cell surface, mobilization of intracellular calcium is induced, which is fol...

Previously, we reported that endoplasmic reticulum calcium stores were a direct target for paclitaxel initiation of apoptosis. Furthermore, the actions of paclitaxel attenuated Bcl-2 resistance to apoptosis through endoplasmic reticulum-mediated calcium release. To better understand the calcium-regulated mechanisms of paclitaxel-induced apoptosis in breast cancer cells, we investigated the role...
