PURPOSE Retinal photoreceptor cells are tonically depolarized in darkness. Ca2+ influx in darkness plays a critical role in the regulation of neurotransmitter release and melatonin synthesis in these sensory cells. The purpose of the present study was to examine the dynamic changes of intracellular Ca2+ concentrations ([Ca2+]in ) in response to a tonic(More)
A new bisphosphonate, disodium dihydrogen (cycloheptylamino) methylene bisphosphonate monohydrate (YM175), was compared with 3-amino-1-hydroxypropylidene-1, 1-bisphosphonate (AHPrBP) and 1-hydroxyethylidene-1,1-bisphosphonate (HEBP) in terms of its effect on tumour induced osteolysis using a bladder tumour in mice (MBT-2). The method consisted of(More)
The relationship between the expression level of putative drug resistance factors and sensitivity to anticancer drugs in human normal renal proximal tubule epithelial cells (RPTEC) and 3 kinds of renal cell carcinoma (RCC) cells, VMRC-RCW (RCW), OS-RC-2 (OS2), TUHR14TKB (14TKB), was examined. RPTEC exhibited high expression of P-glycoprotein (Pgp),(More)
