Amiloride 58-67 glucose-6-phosphate isomerase 1 Mus musculus 25-28 35538691-6 2022 Low pHe reduced intracellular pH (pHi), while amiloride treatment, which is known to reduce pHi, induced c-Src phosphorylation through AhR. Amiloride 46-55 glucose-6-phosphate isomerase 1 Mus musculus 92-95 2574175-4 1989 These pHi changes were dependent on extracellular Na+ and inhibited by amiloride. Amiloride 71-80 glucose-6-phosphate isomerase 1 Mus musculus 6-9 16336655-1 2005 BACKGROUND: Amiloride derivatives, commonly used for their diuretic and antihypertensive properties, can also cause a sustained but reversible decrease of intracellular pH (pHi). Amiloride 12-21 glucose-6-phosphate isomerase 1 Mus musculus 173-176 2835488-6 1988 In the presence of amiloride (0.1 mM) or the absence of Na+, application of ACh caused a significant decrease in pHi and removal of amiloride or replacement with Na+-containing saline, respectively, rapidly increased the pHi. Amiloride 19-28 glucose-6-phosphate isomerase 1 Mus musculus 113-116 2835488-6 1988 In the presence of amiloride (0.1 mM) or the absence of Na+, application of ACh caused a significant decrease in pHi and removal of amiloride or replacement with Na+-containing saline, respectively, rapidly increased the pHi. Amiloride 19-28 glucose-6-phosphate isomerase 1 Mus musculus 221-224 2883187-3 1987 The recovery of pHi to its resting value was blocked by the removal of extracellular Na+, by the addition of extra-cellular H+, and by the addition of analogs of amiloride selective for inhibition of Na+/H+ exchange. Amiloride 162-171 glucose-6-phosphate isomerase 1 Mus musculus 16-19 23428-13 1977 Amiloride (10(-4)M) reversibly reduced the rate of pH(i) recovery to much the same extent as removal of external Na. Amiloride 0-9 glucose-6-phosphate isomerase 1 Mus musculus 51-56 3254411-15 1988 In HCO3- -free solution pHi recovery was completely blocked when either Na+ was removed or when amiloride was applied indicating an exclusive activation of the Na+-H+ exchanger. Amiloride 96-105 glucose-6-phosphate isomerase 1 Mus musculus 24-27 2835488-6 1988 In the presence of amiloride (0.1 mM) or the absence of Na+, application of ACh caused a significant decrease in pHi and removal of amiloride or replacement with Na+-containing saline, respectively, rapidly increased the pHi. Amiloride 132-141 glucose-6-phosphate isomerase 1 Mus musculus 221-224 3367375-4 1988 After myocytes were acid-loaded with NH4Cl, the pHi recovered from acidosis to the resting level within a few minutes via amiloride-sensitive Na+/H+ exchange. Amiloride 122-131 glucose-6-phosphate isomerase 1 Mus musculus 48-51 3367375-6 1988 The inhibition of the pHi recovery from acidosis by ouabain is possibly caused by an inhibition of amiloride-sensitive Na+/H+ exchange, which is secondary to a suppression of Na+ efflux through (Na+, K+) pump. Amiloride 99-108 glucose-6-phosphate isomerase 1 Mus musculus 22-25 6338733-4 1983 Amiloride, a specific blocker of the transmembrane sodium proton exchange, has been used to demonstrate that this mechanism is also operative in the beta-cell membrane in the control of pHi. Amiloride 0-9 glucose-6-phosphate isomerase 1 Mus musculus 186-189 8554515-5 1995 Recovery of pHi in L1210 cells after a nigericin- or NH4(+)-mediated acid load in HCO3(-)-free buffers was mediated by Na+/H+ antiporter activity, in addition to a minor Na(+)-independent and amiloride-insensitive pathway. Amiloride 192-201 glucose-6-phosphate isomerase 1 Mus musculus 12-15 15193158-6 2004 Islet pHi was altered using amiloride, removal of medium Cl-, and changing medium pH. Amiloride 28-37 glucose-6-phosphate isomerase 1 Mus musculus 6-9 12493726-6 2003 The Na(+)-dependent rate of pH(i) recovery was also inhibited by amiloride, indicating H(+) extrusion through NHEs; however, the amiloride sensitivity of the apical membrane was less than that of the basolateral membrane, suggesting the involvement of different types of NHEs in the two membranes. Amiloride 65-74 glucose-6-phosphate isomerase 1 Mus musculus 28-33 12493726-6 2003 The Na(+)-dependent rate of pH(i) recovery was also inhibited by amiloride, indicating H(+) extrusion through NHEs; however, the amiloride sensitivity of the apical membrane was less than that of the basolateral membrane, suggesting the involvement of different types of NHEs in the two membranes. Amiloride 129-138 glucose-6-phosphate isomerase 1 Mus musculus 28-33 9501924-10 1997 Our data indicate that the Na+/H+ exchanger is involved in this process, since acid load and pHi-recovery experiments showed the alkalization to be amiloride-sensitive. Amiloride 148-157 glucose-6-phosphate isomerase 1 Mus musculus 93-96 9298595-5 1997 Amiloride (1 mM) of 5-(N-ethyl-N-isopropyl)-amiloride (10 microM), two previously reported inhibitors of the Na+/H+ exchangers, mimicked the effects produced by 2H2O on pHi and PtdCho turnover. Amiloride 0-9 glucose-6-phosphate isomerase 1 Mus musculus 169-172 9407593-2 1997 Coadministration of amiloride increases the incidence and severity of acetazolamide-induced forelimb malformations and further reduces limb bud pHi. Amiloride 20-29 glucose-6-phosphate isomerase 1 Mus musculus 144-147 1311525-2 1992 When the apical Na(+)-H+ antiporter was inhibited in the absence of AVP with removal of luminal Na+ plus addition of 0.5 mM amiloride, a small but significant increase in pHi was observed after luminal NH4Cl-induced acidification of MTAL cells to pHi less than 6.7. Amiloride 124-133 glucose-6-phosphate isomerase 1 Mus musculus 171-174 8638256-12 1995 However, treatment with acetazolamide plus amiloride for 15 hr produced a marked reduction of pHi values throughout the forelimb bud. Amiloride 43-52 glucose-6-phosphate isomerase 1 Mus musculus 94-97 8381657-0 1993 Therapeutic potential of analogues of amiloride: inhibition of the regulation of intracellular pH as a possible mechanism of tumour selective therapy. Amiloride 38-47 glucose-6-phosphate isomerase 1 Mus musculus 95-97 8381657-3 1993 Amiloride and its analogues DMA (5-(N,N-dimethyl)amiloride), MIBA (5-(N-methyl-N-isobutyl)amiloride) and EIPA (5-(N-ethyl-N-isopropyl)amiloride) are known to inhibit the Na+/H+ antiport and therefore decrease the cells ability to regulate pHi. Amiloride 0-9 glucose-6-phosphate isomerase 1 Mus musculus 239-242 8393012-3 1993 Na/H exchange was assayed as the Na-dependent, amiloride-sensitive component of pHi recovery from an acid load induced by a pulse of NH3/NH4-containing solution. Amiloride 47-56 glucose-6-phosphate isomerase 1 Mus musculus 80-83 8393012-9 1993 In addition, a putative Na/HCO3 cotransport system was monitored as a Na-dependent, amiloride-insensitive pHi recovery mechanisms that was inhibited by 200 microM H2DIDS. Amiloride 84-93 glucose-6-phosphate isomerase 1 Mus musculus 106-109 1396416-11 1992 Amiloride, a Na(+)-H+ exchange inhibitor, decreased the pHi of both DBA and C57 astrocytes more in HEPES HBSS than in HCO3- HBSS. Amiloride 0-9 glucose-6-phosphate isomerase 1 Mus musculus 56-59 1503904-2 1992 Cell killing is enhanced when these agents are used in combination with compounds (amiloride, 4,4"-diisothiocyanostilbene-2,2"-disulfonic acid (DIDS)) which inhibit the membrane-based exchangers responsible for the regulation of intracellular pH (pHi). Amiloride 83-92 glucose-6-phosphate isomerase 1 Mus musculus 247-250 1588302-9 1992 The rate of cellular NH4+ influx in IP-MTAL due to the apical Ba(2+)-sensitive NH4+ transport pathway was sensitive to reduction in cytosolic pH whether pHi was changed by acidifying the basolateral medium or by inhibition of the apical Na+:H+ exchanger with amiloride at a constant pHo of 7.4. Amiloride 259-268 glucose-6-phosphate isomerase 1 Mus musculus 153-156 1311525-2 1992 When the apical Na(+)-H+ antiporter was inhibited in the absence of AVP with removal of luminal Na+ plus addition of 0.5 mM amiloride, a small but significant increase in pHi was observed after luminal NH4Cl-induced acidification of MTAL cells to pHi less than 6.7. Amiloride 124-133 glucose-6-phosphate isomerase 1 Mus musculus 247-250 1311525-6 1992 In the absence of AVP, addition of 0.5 mM amiloride to the luminal perfusate reduced steady-state pHi by 0.40 +/- 0.07 units, whereas exposure of the basolateral membrane to the same concentration of amiloride had no effect on pHi (delta pHi = 0.01 +/- 0.01 units). Amiloride 42-51 glucose-6-phosphate isomerase 1 Mus musculus 98-101 1311525-6 1992 In the absence of AVP, addition of 0.5 mM amiloride to the luminal perfusate reduced steady-state pHi by 0.40 +/- 0.07 units, whereas exposure of the basolateral membrane to the same concentration of amiloride had no effect on pHi (delta pHi = 0.01 +/- 0.01 units). Amiloride 42-51 glucose-6-phosphate isomerase 1 Mus musculus 227-230 1311525-6 1992 In the absence of AVP, addition of 0.5 mM amiloride to the luminal perfusate reduced steady-state pHi by 0.40 +/- 0.07 units, whereas exposure of the basolateral membrane to the same concentration of amiloride had no effect on pHi (delta pHi = 0.01 +/- 0.01 units). Amiloride 42-51 glucose-6-phosphate isomerase 1 Mus musculus 227-230 1311525-7 1992 AVP reduced the magnitude of cell acidification on exposure of apical membranes to amiloride (delta pHi = 0.16 +/- 0.03) but increased the pHi response to basolateral amiloride (delta pHi = 0.09 +/- 0.00). Amiloride 167-176 glucose-6-phosphate isomerase 1 Mus musculus 139-142 1311525-7 1992 AVP reduced the magnitude of cell acidification on exposure of apical membranes to amiloride (delta pHi = 0.16 +/- 0.03) but increased the pHi response to basolateral amiloride (delta pHi = 0.09 +/- 0.00). Amiloride 167-176 glucose-6-phosphate isomerase 1 Mus musculus 139-142 1964210-7 1990 This Na(+)-induced increase in pHi was almost completely inhibited by 0.5 mmol/l amiloride and was associated with a rapid, amiloride-sensitive increase in aNai. Amiloride 81-90 glucose-6-phosphate isomerase 1 Mus musculus 31-34 1914146-6 1991 Recovery of pHi after NH4Cl prepulse was markedly inhibited in low-Na+ and in amiloride-containing HEPES HBSS. Amiloride 78-87 glucose-6-phosphate isomerase 1 Mus musculus 12-15 1847362-2 1991 We investigated the possible relationship between changes in the thermal response of SCK mouse mammary tumor cells in vitro and changes in intracellular pH (pHi) due to amiloride in the present study. Amiloride 169-178 glucose-6-phosphate isomerase 1 Mus musculus 157-160 1847362-6 1991 The presence of 0.5 mM amiloride significantly reduced pHi in both pH 7.2 and 6.6 medium. Amiloride 23-32 glucose-6-phosphate isomerase 1 Mus musculus 55-58 1847362-8 1991 The combined effect of heat and amiloride in reducing the pHi of SCK cells was additive. Amiloride 32-41 glucose-6-phosphate isomerase 1 Mus musculus 58-61 1847362-9 1991 These results suggest that the effects of amiloride on the thermal response of SCK cells might be mediated in part by a decrease in pHi. Amiloride 42-51 glucose-6-phosphate isomerase 1 Mus musculus 132-135 1964210-7 1990 This Na(+)-induced increase in pHi was almost completely inhibited by 0.5 mmol/l amiloride and was associated with a rapid, amiloride-sensitive increase in aNai. Amiloride 124-133 glucose-6-phosphate isomerase 1 Mus musculus 31-34 2156445-6 1990 Recovery of pHi was dependent on luminal Na+ (apparent Km = 13.2 +/- 3.2 mM) and was inhibited by amiloride (apparent Ki = 10.6 microM), consistent with the activity of an apical Na(+)-H+ antiporter. Amiloride 98-107 glucose-6-phosphate isomerase 1 Mus musculus 12-15 2107748-5 1990 Steady-state pHi of BC3H-1 cells in NHB acidified reversibly on exposure to 0.5 mM 4,4"-diisothiocyanostilbene-2,2"-disulfonic acid (DIDS; 1.4 +/- 0.3 x 10(-4) pH/s), 1 mM amiloride (2.0 +/- 0.7 x 10(-4) pH/s), or Na-free solution (8.3 +/- 2.4 x 10(-4) pH/s) and alkalinized upon exposure to Cl-free solutions (9.7 +/- 2.2 x 10(-4) pH/s). Amiloride 172-181 glucose-6-phosphate isomerase 1 Mus musculus 13-16 2107748-7 1990 This new steady-state pHi acidified very slowly upon exposure to 1 mM amiloride (0.3 +/- 0.1 x 10(-4) pH/s), acidified more rapidly upon exposure to 0.5 mM DIDS (5.9 +/- 0.6 x 10(-4) pH/s) or Na-free solutions (9.8 +/- 1.0 x 10(-4) pH/s), and alkalinized on exposure to Cl-free solutions (24.5 +/- 1.3 x 10(-4) pH/s).
