Background: Angiogenesis is closely related to the growth, invasion and metastasis of the tumor, also anticancer therapy key targets. Scutellaria barbata D. Don (S. barbata), a traditional Chinese medicine, is being used for treatment of many diseases including cancer. However, the antitumor molecular mechanism of S. barbata was unclear. This study is aimed to investigate the inhibitory effect ...

A new cefoxitin-agar medium (CAM)-based assay was compared to the previously published modified three-dimensional (M3D) assay for the detection of AmpC production in Escherichia coli and Klebsiella pneumoniae. Clinical isolates of cefoxitin-resistant E. coli (n = 5) and K. pneumoniae (n = 7) and multiple control strains with and without AmpC enzymes were tested by both methods. The CAM method w...

Cav1.2 Ca(2+) channel activity diminishes in inside-out patches (run-down). Previously, we have found that with ATP, calpastatin domain L (CSL) and calmodulin (CaM) recover channel activity from the run-down in guinea pig cardiac myocytes. Because the potency of the CSL repriming effect was smaller than that of CaM, we hypothesized that CSL might act as a partial agonist of CaM in the channel-r...

BACKGROUND The Lutheran blood group glycoprotein (Lu), an Ig superfamily (IgSF) transmembrane receptor, is also known as basal cell adhesion molecule (B-CAM). Lu/B-CAM is a specific receptor for laminin α5, a major component of basement membranes in various tissues. Previous reports have shown that Lu/B-CAM binding to laminin α5 contributes to sickle cell vaso-occlusion. However, as there are n...

Photodynamic therapy has been developed as an alternative therapy of cancer. The aim of this study was to examine whether PDT with hexenyl ester of 5-aminolaevulinic acid (ALA-hx) inhibits the proliferation of the salivary gland adenocarcinoma SGT cells. Cell proliferation was examined by MTT assay. The gene expression of Coproporphyrinogen oxidase (CPO) and ROS production was also examined. Fl...

Kv7.2 (KCNQ2) is the principal molecular component of the slow voltage gated M-channel, which strongly influences neuronal excitability. Calmodulin (CaM) binds to two intracellular C-terminal segments of Kv7.2 channels, helices A and B, and it is required for exit from the endoplasmic reticulum. However, the molecular mechanisms by which CaM controls channel trafficking are currently unknown. H...

The association of soluble Ca/calmodulin-dependent protein kinase II (CaM kinase II) with postsynaptic densities (PSDs) was determined by activity assay, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and immunoblotting of the enzyme. Soluble CaM kinase II was autophosphorylated with ATP in the presence of Ca and calmodulin, and then it was incubated with PSDs. Autophosphorylated Ca...

The association of soluble Ca2+/calmodulin-dependent protein kinase II (CaM kinase II) with postsynaptic densities (PSDs) was determined by activity assay, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and immunoblotting of the enzyme. Soluble CaM kinase II was autophosphorylated with ATP in the presence of Ca2+ and calmodulin, and then it was incubated with PSDs. Autophosphorylate...

The purpose of this current study was to justify the incorporation of complementary and alternate medicine (CAM) in current cancer treatments. The major drawback of anticancer drugs is their nonselective killing, which ultimately leads to attrition of normal cells. Keeping this as the foundation of our study, we made an effort to compare the cytotoxicity associated with a known chemotherapeutic...
