Phosphoinositide-specific phospholipase $C\delta$$PLC\delta$) plays an important role in many cellular responses and is involved in the production of second messenger. The present study was conducted to obtain the biochemical characteristics of the expressed recombinant $PLC\delta$ in E. coli cloned from Misgurnus mizolepis and partially purified $PLC\delta$ enzymes from liver tissues of M. mizolepis (wild ML-$PLC\delta$). The ML $PLC\delta$ gene was cloned and expressed under the previous report (Kim et al., 2004), and purified the recombinant protein by successive chromatography using $Ni^{2+}$-NTA affinity column and gel iltration FPLC column. The wild ML-$PLC\delta$ protein was solublized with 2 M KCI and purified by successive chromatography on open heparin-Sephagel and analytical TSKgel heparin-5PW. Both the recombinant and wild ML-$PLC\delta$ form of protein showed a concentration-dependent PLC activity to phosphatidylinositol 4,5-bis-phosphate (PIP$_2$) or phosphatidylinositol (PI). Its activity was absolutely $Ca^{2+}$- dependant, which was similar to mammalian $PLC\delta$ isozymes. Maximal PI-hydrolytic activations of recombinant and wild ML- TEX>$PLC\delta$ was at pH 7.0 and pH 7.5, respectively. In addition, the enzymatic activities of recombinant and wild ML-$PLC\delta$ were increased in concentration-dependent manner by detergent, such as sodium deoxycholate SDC), phosphatidylethanolamine (PE) and phosphatidylcholine (PC). The activities decreased in contrast by a polyamine, such as spermine. Western blotting showed that several types of $PLC\delta$ isozymes exist in various organs. Taken together our results, it suggested that the biochemical characteristics of ML-$PLC\delta$ are similar with those of mammalian $PLC\delta1$ and ${\delta}3$ isozymes.
The present study performed the isolation of cytosolic ascorbate peroxidase (APX) isozymes and analyzed the pattern of their activity development and also investigated the change in some other enzyme activities related to the ascorbate-glutathione pathway from the senescing wheat leaves. The aim of this work is to examine the possibility that in the cytoplasm of wheat leaves the ascorbate-glutathione pathway p!ays a significant role in relation to leaf senescence involving an $H_2O_2$ accumulation and then to show the effect of benzyladenine (BA) on that pathway. During the leaf senescence characterized by increases in ChI breakdown and H202 accumulation under the 4-day dark incubation of matured leaf segments; i) no significant increase of total cytosolic APX was observed, ii) a dehydroascorbate reductase (DHAR) activity was decreased rapidly, iii) a slight increase of glutathione reductase (GR) activity occurred. In the BA-treated leaves; however, i) the total activity of APX increased conspicuously, ii) the decrease of DHAR activity was relatively inhibited, iii) the GR activity increase was more enhanced, and iv) the decrease of ascorbate content and the increase of H202 content were retarded as compared with those of control leaves. Three isozymes of cytosolic APX were found by using a native-electrophoretic gel in senescing wheat leaves and two of them occurred with major activity. In the developmental patterns of cytosolic APX isozymes, only two isozyme bands ("a" and "b") appeared with almost constant activity through 4 days of incubation in the control leaves, while one additional weak isozyme band ("c") and a little increase of "b" isozyme activity were detected in the BA-treated leaves. EspeciaUy, the development of "a" isozyme activity increased remarkably compared with that of control leaves. The increased capacity for peroxide scavenging due to the enhanced activity of all 3 enzymes (APX, DHAR, GR) participating in the ascorbate-glutathione pathway in BA-treated leaves suggested that this pathway might playa significant role in the processes related to the wheat leaf senescence.scence.
The aim of this study was to examine the metabolic adjustment of lactate dehydrogenase (EC 1.1.1.27, LDH) isozymes to the environmental temperature in bluegill (Lepomis macrochirus). This study included three groups of bluegill collected in April (group Ⅰ), May (group Ⅱ), and September (group Ⅲ). The LDH activities of skeletal muscle, heart, and brain tissues were higher in group Ⅲ than in groups Ⅰ and Ⅱ. The citrate synthase (EC 4.1.3.7, CS) activity was higher in skeletal muscle but lower in heart and brain tissues of group Ⅱ as compared to group Ⅰ. In contrast, the CS activity was lower in skeletal muscle and higher in heart and brain tissues in group Ⅲ than in group Ⅱ. Furthermore, the LDH/CS activity ratio was higher in the skeletal muscle and brain in group Ⅲ than in groups Ⅰ and Ⅱ. Accordingly, anaerobic metabolism was increased in group Ⅲ. LDH A4, A2B2, and B4 isozymes were expressed in skeletal muscle, heart, liver, and brain tissues. The LDH C hybrid was detected in brain tissue. The LDH A4 isozyme was successfully purified by affinity chromatography. The molecular weight of the purified LDH A4 isozyme was 136 kDa and its optimal pH for enzymatic activity was 8.0. The KmPYR values of LDH in skeletal muscle were 0.161-0.227 mM using pyruvate as a substrate. These kinetic properties of LDH in skeletal muscle are consistent with the fact that bluegill is a cold-adapted species. These results may be useful for predicting the habitat use of this fish.
OA-8159, a new Phosphodiesterase (PDE) 5 inhibitor, has exhibited potent erectogenic potential in a penile erection test in rats and anesthetized dogs. In this study, we investigated the mechanism of its erectogenic activity by measuring the activity of OA-8159 against a various PDE isozymes and assessing cGMP and cAMP formation in a rabbit corpus cavernosum in vitro. DA-8159 inhibited the PDE 5 activity in rabbit and human platelets, which the $IC_{50}$ was 5.84$\pm$1.70 nM and 8.25$\pm$2.90 nM, respectively. The $IC_{50}$ of DA-8159 on PDE 1, PDE2, PDE 3 and PDE 6 were 870$\pm$57.4 nM, $101\pm$5 $\mu$M, 52.0$\pm$3.53 $\mu$M and 53.3$\pm$2.47 nM, respectively. This suggests that DA-8159 is a potent, highly selective, competitive inhibitor of PDE 5-catalyzed cGMP hydrolysis. The rates of cGMP hydrolysis catalyzed by human platelets-derived PDE 5 as a function of the cGMP concentration (5~100 nM) and two-fixed DA-8159 concentration (11.3 and 18.8 nM) were investigated in order to characterize the mode of PDE 5 inhibition by DA-8159. DA-8159 increased the apparent 4K_{m}$ value for cGMP hydrolysis but had no effect on the apparent $V_{max}$, indicating a competitive mode of inhibition. DA-8159 increased the cGMP concentrations in the rabbit corpus cavernosum dose dependently. In the presence of sodium nitroprusside (SNP), DA-8159 significantly sti\mulated the accu\mulation of cGMP when compared to the control level. This indicated that the enhancement of a penile erection by DA-8159 involved the relaxation of the cavernosal smooth \muscle by NO-sti\mulated cGMP accu\mulation. In conclusion, DA-8159 is a selective inhibitor of PDE 5-catalyzed cGMP hydrolysis and the enhancement of a penile erection by DA-8159 is mediated by the relaxation of the cavernosal smooth \muscle by the NO-sti\mulated cGMP accu\mulation.
Poly-pharmacy has been on the rise because of aging of population and chronic disease. Most of drug metabolism happens in the liver by CYP isozymes and the metabolism by CYP450 enzymes. The Cytochrome P450 (CYP) is a superfamily of enzymes that catalyzes the oxidations of many endogenous and exogenous compounds. Primary human Hepatocytes (HH) are considered as the gold standard model for In vitro drug interaction studies. However, there are several limitations (cost, limited life span) for using HH cells. HepaRG cells are being used as a possible alternative. HepaRG cells were cultured in William E medium containing the positive control inducers (1A2: 10, 25, 50 ${\mu}M$ omeprazole, 2C9 and 2C19: 10 ${\mu}M$ rifampin, 3A4: 10, 25, 50 ${\mu}M$ rifampin) at $37^{\circ}C$, 5 % $CO_2$ in a humidified atmosphere. This study was to evaluate the induction of CYP isozymes (1A2, 2C9, 2C19 and 3A4) using LC-MS/MS. We evaluated the potential induction ability of Bosentan, as a drug of pulmonary artery hypertension, in HepaRG cells. For reference, dose of the Bosentan is determined to the basis of the $C_{max}$ (835 mg/ml) value. The enzyme activity demonstrated that CYP2C9 and 3A4 were induced up to 20 times by Bosentan. Like as In vivo, the enzyme activity of CYP2C9 and CYP3A4 is significantly induced in a dose-dependent by Bosentan.

Two different ${\alpha}$-amylase isozymes (AMY1 and AMY2) found in barley malt share up to 80% of amino acid sequence identity with each other, but their enzymatic properties differ remarkably. AMY1 shows the highest activity at low concentration of calcium ion, while AMY2 is highly active at high calcium concentration. Meanwhile, BASI (Barley ${\alpha}$-Amylase/Subtilisin Inhibitor) protein specifically inhibits only AMY2. In the present study, three separate regions in AMY genes (I, II, and III) were assigned on the basis of restriction enzyme sites and four kinds of chimeric amylases have been obtained by swapping a part of regions with each other. Each chimera gene was successfully over-expressed in Pichia pastoris. From the results of enzymatic characterization, both AMY211 and AMY122 showed the mixed or intermediate type of calcium-dependent activity between AMY1 and 2. Meanwhile, only AMY221 chimera could be significantly inhibited by BASI protein. As a result, it can be proposed that some amino acid residues in the region I and II, except region III, of barley ${\alpha}$-amylases play very important roles in calcium-dependency and interaction with BASI.

Burkholderia gladioli pv. alliicola CH1 showed typical soft rot symptoms at higher than $20^{\circ}C$ but very weak soft rot symptoms at temperature under $10^{\circ}C$. Among the nine agro-chemicals, oxolinic acid WP, streptomycin + copper hydroxide WP and streptomycin WP were found to be effective for the inhibition of the pathogen in vitro. The results of scanning electron microscopic investigation showed that onion bulbs was macerated by infection of B. gladioli pv. alliicola CH1. B. gladioli pv. alliicola CH1 was able to produce polygalacturonase but did not produce pectin lyase and carboxymethylcellulase. In analysis of the polygalacturonase activity of the isolated pectin-degradation enzymes from B. gladioli pv. alliicola CH1 total protein, three activity bands 45 kDa, 35 kDa, and 29 kDa were detected by the direct (or in-gel) activity staining on SDS-PAGE.
We previously shown that LES contraction depends on $M_3$ receptors linked to PTX insensitive $G_q$ protein and activation of PLC. This results in production of $IP_3$, which mediates calcium release, and contraction through a CaM dependent pathway. In the esophagus ACh activates $M_2$ receptors linked to PTX sensitive $G_{i3}$ protein, resulting in activation of PLD, presumably, production of DAG. We investigated the role of PLC isozymes which can be activated by $G_q$ or $G{\beta}$ protein on ACh-induced contraction in LES and esophagus. Immunoblot analysis showed the presence of 3 types of PLC isozymes, $PLC-{\beta}1$, $PLC-{\beta}3$, and $PLC-{\gamma}1$, but not $PLC-{\beta}2$, $PLC-{\beta}4$, $PLC-{\gamma}2$, $PLC-{\delta}1$, and $PLC-{\delta}2$ from both LES and esophageal muscle. ACh produced contraction in a dose dependent manner in LES and esophageal muscle cells obtained by enzymatic digestion with collagenase. $PLC-{\beta}1$ or $PLC-{\beta}3$ antibody incubation reduced contraction in response to ACh in LES but not in esophageal permeabilized cells, but $PLC-{\gamma}1$ antibody incubation did not have an inhibitory effect. The inhibition by $PLC-{\beta}1$ or $PLC-{\beta}3$ antibody on Ach-induced contraction was antibody concentration dependent. The combination with $PLC-{\beta}_1$ and $PLC-{\beta}_3$ antibody completely abolished the contraction, suggesting that $PLC-{\beta}1$ and $PLC-{\beta}3$ have a synergism to inhibit the contraction in LES. $PLC-{\beta}1$, -${\beta}3$ or -${\gamma}1$ antibody did not reduce the contraction of LES cells in response to DAG ($10^{-6}$ M), suggesting that this isozyme of PLC may not activate PKC. When $G_{q/11}$ antibody was incubated, the inhibitory effect of the incubation of PLC ${\beta}3$, but not of PLC ${\beta}_1$ was additive (Fig. 6). In contrast, when $G_{\beta}$ antibody was incubated, the inhibitory effect of the incubation of PLC ${\beta}_1$, but not of PLC ${\beta}_3$ was additive. This data suggest that $G_{q/11}$/11 or $G{\beta}$ may activate cooperatively different PLC isozyme, $PLC{\beta}_1$ or $PLC{\beta}_3$ respectively.

The effects of exercise and selenium added high fat diet on edurance and serum lipid components were studied in rats. A total of 72 male Sprague-Dawley ($150{\pm}35g$, body weight) were divided into trained group and untrained group and were bred for 7 weeks. Each group had 6 different dietary subgroups; namely, basal diet, 20% shortening and 20% soybean oil subgroup and selenium (0.01mg%) added each subgroups. Exercises of 8-min treadmill running and 10-min swimming were given to the trained group every other day during the experimental period while only treadmill running was given to the untrained group during the last week. The amounts of food intake, changes in body weight and endurance were determined once a week and serum lipid components were measured before and after experimental period. Following are the results obtained : 1) The untrained group took a slightly larger amount of food than that in the trained group. The food efficiency is, however, higher in the trained group. Body weight increased more in untrained group, while high fat diet resulted in greater increment in body weight than that in normal diet groups. 2) The trained group showed remarkably longer endurance than the untrained group and selenium added high fat diet enhanced the effect. 3) The trained group showed lower blood level of T-chol., TG and TG/PL than the untrained group. All the other blood values of HDL-chol., PL, MDL-chol./T-chol., HDL/LDL and A/G ratio were higher in trained group. 4) Soybean oil added dietary groups exibited lower blood levels of T-chol., TG, TG/PL and A/G than those in shortening added dietary groups. On the contrary, the former groups showed higher blood HDL-chol., PL., HDL, HDL-chol. and HDL/LDL ratio than those of soybean oil added dietary groups. 5) $LDH_5$ was the most abundant one among serum LDH isozymes. The electrophoretic pattern of serum LDH isozymes was not changed by exercise training and selenium added high fat diet. 6) Exercise training lowered blood GOT and TBA. These effects were enhanced by soybean oil added diets. From the above results it was concluded that a regular and long term exercise training as well as a small amount of selenium added high fat diet result in reduction of body weight and TBA and improve dietary efficiency and physical endurance in rats.
The metabolism of lactate dehydrogenase (EC 1.1.1.27, LDH) and $C_4$ isozyme were studied in tissues of Coreoperca herzi and Pseudogobio esocinus acclimated to rapid increase of dissolved oxygen (DO). In C. herzi the LDH activity was changed $35-39\%$ in brain and liver tissues, and within $20\%$ in other tissues. The $B_4$ isozyme was increased and isozyme containing subunit C was decreased in muscle tissue. The $B_4$ isozyme was increased in heart and kidney. In P. esocinus, the LDH activity in liver tissues was largely increased to $150\%$ for 30 minute and $70\%$ in other tissues. The $A_4$ isozyme was increased in muscle and $B_4$ isozyme was increased in other tissues. Especially, the metabolism of liver tissue in P. esocinus was regulated by increasing liver-specific $C_4$ and decreasing $A_4$ isozyme. But the metabolism of eye tissue in C. herzi was regulated by decreasing LDH activity and eye-specific $C_4$ isozyme. The LDH activity and LDH isozyme in P. esocinus were largely increased than C. herzi acclimated to rapid increase of DO. And eye-specific $C_4$ and liver-specific $C_4$ isozymes played role as lactate oxidase. Therefore, the response of species acclimated to rapid increase of DO seems to be variable, perhaps due to prior exposure to environmental conditions.
