A molecular entity for Ca2+-dependent Cl- transport has not been well characterized in salivary cells. Here, we identify a rat CLCA homologue (rCLCA1) using a polymerase chain reaction (PCR)-based strategy. The full length of the isoform was 3.3 kb, and the predicted open reading frame encoded a 903-amino acid protein. Immunoblotting using a specific(More)
BACKGROUND AND AIMS Many Orchidaceous species are threatened globally by development and over-collection from their natural habitats for horticultural purposes. Artificial propagation from seeds is difficult in most terrestrial orchids native to temperate regions. Seed production is another limiting factor in the artificial propagation for these species(More)
Several members of the transient receptor potential (TRP)-channel family are expressed in cancer cells. One, cold/menthol-sensitive TRPM8, is reportedly an important player in carcinogenesis in human prostate cancer, although its involvement in oral squamous cell carcinoma (SCC) remains unclear. The present(More)
The effects of a lipid component of oxidized low-density lipoproteins (ox-LDL), l-α-palmitoyl-lysophosphatidylcholine (LPC), on membrane currents of isolated canine renal artery smooth muscle cells (RASMC) were examined using the whole-cell configuration of the patch-clamp technique. In RASMC exposed to nominally Ca2+-free solutions and dialyzed with 0.1 mM(More)
We investigated actions of uridine 5'-triphosphate (UTP) in rat aorta, cerebral and mesenteric arteries, and their single myocytes. UTP (≥10 µM) elicited an inward-rectifying current strongly reminiscent of activation of P2X(1) receptor, and a similar current was also induced by α,β-methylene adenosine 5'-triphosphate (ATP) (≥100 nM). UTP desensitized(More)
We analyzed the proteome of a crenararchaeon, Aeropyrum pernix K1, by using the following four methods: (i) two-dimensional PAGE followed by MALDI-TOF MS, (ii) one-dimensional SDS-PAGE in combination with two-dimensional LC-MS/MS, (iii) multidimensional LC-MS/MS, and (iv) two-dimensional PAGE followed by amino-terminal amino acid sequencing. These methods(More)
Epidermal growth factor (EGF) has recently been localized in salivary, pancreatic, and Brunner's glands in humans, but little is known about its release and its action on gastric secretion. This study, performed on healthy subjects, was designed to determine the release of immunoreactive EGF in plasma and in salivary and gastric secretions under basal(More)
We investigated the significance of milky spots for malignant cells in peritoneal dissemination using three mouse carcinomatous peritonitis models. P388 leukemia and Colon 26 cancer cells were labeled with bromodeoxyuridine (BrdU) and mice were inoculated intraperitoneally. After 24 h the greater omentum and the mesenterium were removed and stained(More)
A new delivery formulation (5FU-MS) of 5-fluorouracil (5FU), 5FU incorporated in microspheres composed of poly(glycolide-co-lactide) matrix, has been developed for the treatment of peritoneal carcinomatosis, and is designed to slowly release the incorporated 5FU for 3 weeks. Intraperitoneal 5FU-MS distributed higher concentrations of 5FU to the(More)
T-type voltage-gated Ca2+ channels have unique electrophysiological properties, suitable for generating Ca2+ oscillations and waves and thus controlling the proliferation of various tumor cells. In the present study, we investigated the role of Cav3.1, a candidate tumor suppressor gene, in neoplastic processes, and compared the differences between Cav3.1(More)
