Abstract
Psoriasis is a chronic, proliferative, and inflammatory skin disease closely associated with inflammatory cytokine production. Cyclophilin A (CypA) is an important proinflammatory factor; however, its role in psoriasis remains unclear. The present data indicate that CypA levels are increased in the lesion skin and serum of patients with psoriasis, which is positively correlated with the psoriasis area severity index. Furthermore, extracellular CypA (eCypA) triggered psoriasis-like inflammatory responses in keratinocytes. Moreover, anti-CypA mAb significantly reduced pathological injury, keratinocyte proliferation, cytokine expression in imiquimod-induced mice. Notably, the therapeutic effect of anti-CypA mAb was better than that of the clinically used anti-IL-17A mAb and methotrexate. Mechanistically, eCypA binds to ACE2 and CD147 and is blocked by anti-CypA mAb. eCypA not only induces the dimerization and phosphorylation of ACE2 to trigger the JAK1/STAT3 signaling pathway for cytokine expression but also interacts with CD147 to promote PI3K/AKT/mTOR signaling-mediated keratinocyte proliferation. These findings demonstrate that the binding of eCypA to ACE2 and CD147 cooperatively triggers psoriasis-like inflammation and anti-CypA mAb is a promising candidate for the treatment of psoriasis.

Quinacrine enhances the efficacy of cisplatin by increasing apoptosis and modulating cancer survival proteins in a colorectal cancer cell line. J Cancer Res Ther 2023; 19:1988-1997.

Abstract
BACKGROUND Cisplatin and platinum-based compounds have been used successfully to treat various cancers. However, their use is often restricted due to the acquired resistance by cancer cells. Over-expression of p53 and inhibition of NF-kB sensitize several cancer cells towards cisplatin-induced apoptosis. Quinacrine, a cytotoxic drug with predictable safety revealed to concurrently suppress NF-kB and activate p53, which may be an attractive adjuvant in cisplatin chemotherapy. Therefore, the objective of the present study was to establish the role of quinacrine as an adjuvant in lowering the dose of cisplatin during cancer therapy to circumvent its toxic effects. MATERIALS AND METHODS The colon cancer (HCT-8) cells were cultured and cell survival assays were performed using standard procedures. Cell cycle arrest and the extent of apoptosis were determined using a muse cell analyzer. Cancer survival proteins were analyzed using western blotting techniques. RESULTS AND CONCLUSION We demonstrated that concomitant use of quinacrine with cisplatin increased cell apoptosis, suppressed cell proliferation and inhibited colony formation in a colorectal cancer cell line. Moreover, cell cycle arrest in the G0/G1 and G2/M phases and upregulation of p53 expression were observed. There was also downregulation of NF-kB and Bcl-xL protein expressions, both of which are associated with enhanced cell apoptosis and an increase in the sensitivity of cancer cells to cisplatin, overcoming its chemoresistance. Overall, the results of the present study and available literature clearly indicate that the use of quinacrine as an adjuvant with cisplatin may enhance its anti-cancer activity and reduce chemoresistance.

Abstract
Renal toxicity is a serious side effect that hinders the use of cisplatin, a commonly used and effective chemotherapeutic agent. Meanwhile, quinacrine is an FDA approved drug that has been stated for its anti-inflammatory effect. Thus, we investigated the ameliorative effect of quinacrine against cisplatin-induced renal toxicity. Single intraperitoneal (i.p.) 10 mg/kg cisplatin administration induced renal injury in rats. Our results showed that 10 mg/kg/day quinacrine decreased the mortality rate of rats from 46.15% (cisplatin group) to 12.5%, and significantly decreased renal tissue fibrosis, relative kidney to body weight ratio, serum creatinine and urea levels compared with the cisplatin group. Indeed, quinacrine significantly decreased renal malondialdehyde concentration and increased renal total antioxidant capacity, compared with the cisplatin group. Furthermore, quinacrine caused significant upregulation of renal sirtuin-1 (SIRT-1) with significant downregulation of intercellular adhesion molecule-1 (ICAM-1) and tumor necrosis factor-α (TNF-α). Moreover, quinacrine significantly blocked cisplatin-induced apoptosis, which was made evident by downregulating renal apoptotic proteins (BAX and p53) and upregulating the renal anti-apoptotic protein BCL2, compared with the cisplatin group. In conclusion, this study demonstrates, for the first time, that quinacrine alleviates cisplatin-induced renal toxicity via upregulating SIRT-1, downregulating inflammatory markers (ICAM-1 and TNF-α), reducing oxidative stress, and inhibiting apoptosis.

Abstract
BACKGROUND Acute kidney injury (AKI) is a serious clinical problem with high rate of mortality and morbidity. Currently used prophylactic and therapeutic strategies to address AKI are limited and warrant further studies. In the present study an attempt was made to investigate the effect of quinacrine, a phospholipase A2 inhibitor against glycerol induced AKI in rats. METHODS Adult female Wistar rats were divided in to five groups. After 24 h of water deprivation rats in groups 3, 4 and 5 received an intraperitoneal injection of quinacrine (3 mg/kg, 10 mg/kg and 30 mg/kg of body weight respectively). Thirty minutes after the first injection of quinacrine animals in groups 3, 4 and 5 received an intramuscular injection of 25% glycerol (10 ml/kg of body weight). The animals in group 2 received 25% glycerol (10 ml/kg of body weight) only whereas rats in group 1 served as control . The quinacrine administration was continued once daily for three days, on the fourth day animals were sacrificed, blood and kidney were collected for various biochemical and histopathological studies. RESULTS Glycerol treatment produced significant renal structural abnormalities and functional impairment (increased urea and creatinine). Increase in myeloperoxidase (MPO) and malondialdehyde (MDA) clearly suggested the involvement of oxidative stress and neutrophilic activity following glycerol administration. Quinacrine dose dependently attenuated glycerol induced structural and functional changes in kidney. CONCLUSION The reversal of glycerol induced AKI by quinacrine points towards a role of phospholipase A2 (PLA2) in the pathogenesis of renal injury. The result of this study suggests that quinacrine may offer an alternative mode of treatment for AKI.

Abstract
1. The effects of dietary vitamin E (DL-alpha-tocopheryl acetate) on carcase and meat quality, oxidative stability, fatty acid composition of muscle lipids, and gene expression related to lipid metabolism were studied in Beijing-you chickens. 2. A total of 360 female birds were distributed among 6 treatments, containing 6 replicates, each of 10 birds. The feed for each treatment was supplemented with vitamin E (0, 10, 50, 100, 150, or 200 mg/kg feed). At 120 d, 30 birds from each treatment were slaughtered to examine the effect of dietary vitamin E supplementation on evaluated traits. 3. The results showed that supplemental vitamin E in diet significantly increased alpha-tocopherol contents of breast and thigh muscles, reduced the drip loss and improved tenderness but did not influence carcase yield, meat colour or pH value 24 h after slaughter. 4. Thiobarbituric acid reactive substance (TBARS) values decreased with increase in dietary vitamin E, and the addition of 100 mg/kg or more vitamin E had a beneficial effect on oxidative stability as indicated by TBARS values during storage up to 7 d. 5. Dietary vitamin E supplementation significantly altered fatty acid composition of breast muscle. Supplementing with 200 mg/kg vitamin E led to lower saturated fatty acids and greater polyunsaturated fatty acids proportions in breast muscle than control and 10 mg/kg vitamin E treatments. 6. Vitamin E supplementation significantly inhibited expression of the cytosolic phospholipase A(2) gene (cPLA(2)) in breast muscle, while enhancing that of the peroxisome proliterator-activated receptor beta (PPAP-beta) and heart fatty acid binding protein genes (H-FABP). The results indicate that dietary supplementation with vitamin E increased lipid stability in muscle and improved meat quality and fatty acid composition, probably by its influence on the expression of genes related to lipid metabolism.

Abstract
OBJECTIVES Long-term treatment with cyclosporine (CsA) results in chronic nephrotoxicity, which is known to be mediated by several cytokines including transforming growth factor-betal. Cytokines are known to play an important role in innate immunity, apoptosis, angiogenesis, cell growth, and differentiation. They are known to be involved in most disease processes, including cancer, cardiac disease, and nephrotoxicity. To evaluate changes of cytokines in a rat model of CsA-induced chronic nephrotoxicity, we performed a cytokine array. METHODS Experiments were performed on two groups of rats; normal control group and CsA-treated group. Cytokine array in rat serum was performed using Cytokine Antibody Array I kit from RayBiotech. RESULTS Serum creatinine, urine creatinine, and creatinine clearance increased in the CsA-treated group. Among the several cytokines, the expressions of the lipopolysaccharide-induced CXC chemokine (LIX), monocyte chemoattractant protein 1 (MCP-1), nerve growth factor (beta-NGF), and tissue inhibitor of metalloproteinase-1 (TIMP-1) in the CsA-treated group were increased above that of cytokines in the control group. The density of the LIX in controls was 0.62, and in the CsA-treated group was 1.24. The density of the MCP-1 in controls was 0.68, and in CsA-treated, 1.43. The density of the beta-NGF in controls was 0.62, and that in CsA-treated, 1.24. The density of the TIMP-1 in controls 1.13, and in CsA-treated, 1.40. CONCLUSIONS Our data suggested that among several cytokines elevated levels of the LIX, MCP-1, beta-NGF, and TIMP-1 are the contributing factors to CsA-induced nephropathy.

Abstract
1. The aim of the present study was to investigate the effects of vitamin E and/or quercetin (Q) on renal function, oxygen radical concentrations in the kidney and some anti-oxidant enzyme activities in rats treated with cyclosporine A (CsA). 2. Groups of rats (270 +/- 15 g), on standard rat chow and water, received all their treatments by gavage for either 4 or 8 weeks. Control groups received either olive oil (0.5 mL) or 25% ethanol (0.5 mL) + olive oil (0.5 mL) per day as vehicle. All experimental groups received 25 mg CsA/kg per day in 0.5 mL olive oil. The vitamin E group received 100 mg vitamin E/kg per day in olive oil in addition to CsA treatment. The quercetin group received 15 mg of Q/kg per day in 0.5 mL of 25% ethanol in addition to CsA treatment. The vitamin E + quercetin group received the two anti-oxidants at the concentrations given in addition to CsA treatment. 3. Quercetin, at a concentration less than one-quarter of vitamin E, was more efficient in lowering blood urea nitrogen, serum creatinine and kidney malondialdehyde in CsA-treated rats. However, neither of the two anti-oxidants was able to normalize these analytes to control values after either 4 or 8 weeks treatment. 4. Quercetin (50 micromol/kg per day) elevated all renal anti-oxidant enzyme activities to values observed in the negative controls. However, vitamin E (232 micromol/kg per day) only normalized glutathione peroxidase activity at the end of either 4 or 8 weeks treatment. Combination treatment with the two anti-oxidants abolished all the ill-effects of CsA. 5. Combination treatment with the two anti-oxidants of renal transplant patients receiving CsA may be beneficial in ameliorating the chronic nephrotoxic effects of the important immunosuppressive drug CsA.

Abstract
Cyclosporine A (CsA) is the first-line immunosuppressant used for the management of solid organ transplantation and autoimmune diseases. Nephrotoxicity is the major limitation of CsA use. Recent evidence suggests that reactive oxygen species (ROS) play an important role in mediating CsA-induced hypertension and nephrotoxicity. Taurine, the major intracellular free beta-amino acid, is known to be an endogenous anti-oxidant and membrane-stabilizing agent. The present study was designed to investigate the effects of taurine on CsA-induced oxidative stress, hypertension and renal dysfunction. 2. Animals were assigned into four groups of seven rats each as follows: (i) control group, receiving vehicle (olive oil; 1 mL/kg, s.c.); (ii) CsA group, given CsA (25 mg/kg per day, s.c.) for 21 days; (iii) taurine group, supplemented with taurine (1% in the drinking water); and (iv) taurine + CsA group, treated with taurine 3 days before and concurrently during CsA injections for 21 days. 3. Cyclosporine A administration elevated blood pressure, reduced serum nitric oxide (NO) levels and deteriorated renal function, as assessed by increased serum creatinine levels and proteinuria and reduced urine flow rate and creatinine clearance compared with vehicle-treated rats. Cyclosporine A induced oxidative stress, as indicated by increased renal tissue concentrations of thiobarbituric acid-reactive substances and reduced concentrations of renal glutathione, glutathione peroxidase and superoxide dismutase. Conversely, no change was noted in renal catalase activity. Moreover, the kidneys of CsA-treated rats showed interstitial inflammation and renal tubular atrophy. 4. Taurine markedly reduced elevated blood pressure, attenuated renal dysfunction and the reduction in serum NO levels and counteracted the deleterious effects of CsA on oxidative stress markers. Furthermore, taurine ameliorated CsA-induced morphological changes. 5. These data clearly indicate the protective potential of taurine against CsA-induced hypertension and nephrotoxicity and suggest a significant contribution of its anti-oxidant property to this beneficial effect.

Abstract
OBJECTIVES It has been demonstrated that immunosuppressive drug cyclosporine A (CsA) increases the synthesis of reactive oxygen species (ROS) and lipid peroxidation products in vitro and in vivo studies, but its possible toxic effects in ovary tissue have not been defined yet. This study was designed to elucidate possible relation between CsA treatment and oxidant/antioxidant status in rat ovary tissue and, to determine if antioxidant supplementation is beneficial. METHODS CsA and black grape extracts were given to rats orally for 10 days. In each group (control, CsA, CsA plus black grape and black grape alone), there were 7 animals (28 rats in total). After the animals were sacrificed, their ovaries were removed to be used in the measurement of malondialdehyde (MDA) level and activities of superoxide dismutase (SOD), catalase (CAT) and xanthine oxidase (XO) enzymes. RESULTS In the control, CsA plus black grape and black grape alone groups, MDA levels were significantly lower than CsA group. Xanthine oxidase activities were significantly higher in CsA and CsA plus black grape groups than control group. In addition, XO activity was significantly lower in black grape alone group than all the other groups including control group. There were no significant differences in the activities of SOD and CAT enzymes between the groups. CONCLUSION The results suggest that CsA leads to oxidant stress and peroxidation in rat ovary tissues mainly due to increased XO activity. It has been suggested that this oxidant stress and peroxidation reactions can be prevented by antioxidant food supplementation like black grape.

Abstract
INTRODUCTION Nephrotoxicity is a clinically important side effect of cyclosporine (CsA). CsA-induced nephrotoxicity results from increased production of free radical species in the kidney. Epigallocatechin gallate (EGCG) acts as an antioxidant, thus, EGCG may have a protective effect on the alteration of renal function resultant from oxygen free radicals. The purpose of the present study was to investigate the protective effect of EGCG in a rodent model. METHODS Experiments were performed on 3 groups. The normal control group (group 1) received normal saline solution. The CsA-treated group (group 2; 15 mg/kg body weight/d for 14 days) received subcutaneous injections. The EGCG-treated group (group 3) in addition received 25 mg of EGCG/kg body weight by intraperitoneal injection. RESULTS There were significant increases in levels of blood urea nitrogen (BUN)(42.8 +/- 8.2 mg/dL; P < .001), serum creatinine (1.18 +/- 0.60 mg/dL; P < .05), and serum malondialdehyde (3.09 +/- 0.20 nmol/mL; P < .001), and a significant decrease in CCr(0.07 +/- 0.02 mL/min; P < .001) in group 2 compared with group 1. Levels of BUN (30.2 +/- 0.7 mg/dL; P < .01)and CCr (0.12 +/- 0.08 mL/min) were lower in group 3 than in group 2. Serum creatinine (0.71 +/- 0.04 mg/dL) and serum malondialdehyde level (2.13 +/- 0.15; P < .001 nmol/mL) were lower in group 3 than in group 2. There was no significant difference in CsA levels between group 2 (6.86 +/- 1.48 mug/mL) and group 3 (6.69 +/- 0.62 mug/mL). CONCLUSIONS EGCG treatment significantly protected renal function and free radical-mediated injury in the kidney from CsA-induced changes.

Abstract
In the past two decades, transplantation has become a preferred modality of treatment of end-stage failure of vital organs. Currently, with the significant improvement in short-term graft survival rates, the main effort is concentrated on prolonging the functional life span of transplanted organs. One of the theories which were put forward to explain the progressive deterioration of transplant function was that of replicative senescence. Senescence of an organ or tissue results from age and/or environmental stress-dependant modification of cellular function. With time, the accumulation of cellular alterations may lead to deleterious effects in various organs and tissues and adversely affect transplants. In this article we are reviewing the candidate mechanisms of senescence such as telomere shortening, genetic regulation and environmental-'toxic' factors and are examining the implications of the theory of replicative senescence for organ allograft. We are also presenting our experiments with renal ischemia/reperfusion in rat serving as a model of kidney transplantation, where baseline kidney telomere length and novel marker of cellular senescence--senescence associated beta-Galactosidase (SA-Gal) expression in tissue served as markers. For the first time in vivo, we were able to show that with aging of the animals the amount of senescent cells in kidney tissue was increasing, while the average renal tissue telomere length was decreasing. The degree of tissue senescence, as determined by amount of SA-Gal positively stained cells, was inversely correlated with the recovery of the kidney function after ischemia/reperfusion injury. These results confirm the theory of replicative senescence in organ ischemia for the first time in vivo, and quantitatively validate the direct correlation between the amount of senescent cells in the organ and its susceptibility to ischemic injury. We conclude that recent advances in study of the cellular basis of senescence, in vitro and especially in vivo, may hold clues to the understanding of events which could be implicated in the damage or protection of organ allografts.

Abstract
Quinacrine has been used for decades and the beneficial effects of this drug are as numerous as its toxic effects. Since endothelial cells (EC) are in many cases the first cells coming in contact with drugs, the effect of quinacrine on certain aspects of EC biology were studied. The presented data demonstrate that quinacrine can have a marked impact on the integrity on EC monolayer without grossly interfering with cell viability. The described impact of quinacrine on EC might explain, at least in part, the toxic effects of this drug observed in the past. Furthermore, quinacrine profoundly effects gene regulation in EC. Quinacrine binds to DNA in a sequence-specific manner. While NF-kappa B-DNA interactions are not effected, AP-1-DNA binding is blocked by quinacrine. Such differential effects are presumably due to intercalation of quinacrine into the AP-1 consensus element. Preincubation of oligonucleotides resembling this sequence blocked the subsequent binding of nuclear extract containing AP-1 protein(s). Taken together, these data suggest that quinacrine interferes with EC physiology and alters the repertoire of EC to respond to stimuli. Furthermore, the differential effects of quinacrine might be exploited to study and gain additional insight in the involvement of AP-1 and NF-kappa B in gene regulation.

Abstract
1. We investigated the simultaneous effects of cyclosporine A (CsA) treatment in rats on glutathione metabolism, oxidative status and their interorgan relationship in the liver and kidney. 2. Reduced and oxidized glutathione (GSH and GSSG, respectively), lipid peroxidation and the activity of several enzymes of the glutathione cycle were evaluated in adult Wistar rats treated daily (i.p.) with saline, CsA vehicle (olive oil) or CsA (10 and 20mg/kg per day) for either 1 or 4 weeks (short- and long-term treatments, respectively). 3. Cyclosporine A treatment elicited a significant depletion in liver GSH content and a decrease in the GSH/GSSG ratio that was unrelated to either the time of treatment or the dose used; these effects were already evident after 1 week of treatment. Renal GSH levels remained unaffected or increased, while those of GSSG increased markedly in all CsA-treated rats, leading to decreases in the GSH/GSSG ratio, except in rats treated in the short term with the lower dose of CsA. These changes in the GSH/GSSG ratio were time and dose dependent. Short-term CsA treatment using the higher dose and long-term treatment with both doses of CsA progressively enhanced lipid peroxidation, which was reflected by increased levels of thiobarbituric acid-reactive substances in both hepatic and renal homogenates. Hepatic gamma-glutamylcysteine synthetase activity was increased after long-term treatment with both doses of CsA, whereas the activity of GSH hepatic peroxidase and GSH transferase was not significantly modified in any of the experimental groups. In contrast, renal gamma-glutamyl transpeptidase activity decreased in a progressive fashion, with the magnitude of this decrease being dose and time dependent. The plasma levels of total glutathione increased only in rats treated in the long term, regardless of the dose of CsA used, and remained unaltered in animals treated in the short term. 4. In summary, the data collected indicate that CsA treatment alters the interorgan homeostasis of glutathione and the oxidative status of the rat liver and kidney, which is associated with increases in lipid peroxidation in both organs, and also induces modifications in the activity of some enzyme related to the glutathione cycle.

Abstract
Cyclosporin A is a widely used immunosuppressive drug having toxic side effects, in particular on kidneys and liver, as a result of its action on different molecular targets. Here we demonstrate that low doses of CsA are able to induce the expression of the heat shock protein HSP27 and its hyperphosphorylation. It also activates the two heat shock transcription factors, HSF1 and HSF2. Since these factors have been shown to be activated by proteasome inhibition, we tested the hypothesis that the inhibitory action of CsA on the proteasome might be responsible for the activation of HSFs and the subsequent expression of HSP27. The increase in multiubiquitinated proteins as well as the stabilization of p53 following CsA addition argues in favor of this hypothesis. The kidney BSC-1 cells are highly responsive to the addition of CsA: the possible link between HSP27 induction and hyperphosphorylation and nephrotoxicity is discussed.

Abstract
BACKGROUND The clinical significance of biopsies showing both rejection and isometric tubular vacuolization has not been well defined in the literature. METHODS The clinical picture, sequential histopathologic findings, and response to therapy were compared between 24 renal allograft biopsies showing both tubular vacuolization and rejection and 14 biopsies showing vacuolization alone. RESULTS The rejection was categorized as grade 1 in 4/24 (16.6%), grade 2A in 10/24 (41.6%), and grade 2B in 10/24 (41.6%) cases (Banff schema, 1993-1995). Treatment with additional steroids and tacrolimus led to a decrease in the interstitial inflammation score (2.6+/-0.1 to 1.3+/-0.1, P<0.001), tubulitis score (2.6+/-0.1 to 1.1+/-0.1, P<0.001), and serum creatinine (4.4+/-2.2 mg/dl to 3.3+/-2.6 mg/dl, P=0.001). Complete response, partial response and no response to antirejection therapy were observed in 16/24 (66.7%), 3/24 (12.5%), and 5/24 (20.8%) patients, respectively. Although there was a rise in the plasma (1.4+/-0.2 ng/ml to 2.8+/-0.3 ng/ml, P<0.001) and whole blood (16.5+/-2.8 ng/ml to 31.2+/-5.7 ng/ml, P<0.001) tacrolimus levels, repeat biopsy showed no change in the size or extent of tubular vacuolization (mean score 2.88+/-0.19 vs. 2.83+/-0.21). The morphologic characteristics of the tubular vacuoles in these cases did not differ from those observed in 14 cases of tacrolimus nephrotoxicity not complicated by rejection. CONCLUSION Patients with concurrent acute rejection and tubular vacuolization usually benefit from increased immunosuppression. The pathogenesis of the vacuolization in this clinical setting is not clear, but may reflect immune-mediated tubular injury.

Abstract
BACKGROUND/AIMS Biliary glutathione appears to be a major osmotic factor in the generation of bile acid-independent bile flow. This study was designed to investigate its importance in cyclosporine A-induced cholestasis in both acute and short-term-treated rats. METHODS Adult male Wistar rats were treated as follows: (i) with a single i.v. dose of cyclosporine or its vehicle (acute assays); (ii) with cyclosporine, its vehicle or physiological saline, i.p., for 7 days once per day (short-term treatment assays). Bile flow and biliary glutathione levels were determined under anesthesia both before and after intrabiliary hydrolysis of the tripeptide had been inhibited. RESULTS Acute cyclosporine administration, at a dose of 20 mg/kg, brought about an abrupt and marked fall in bile flow and bile acid secretion simultaneously with a rapid decrease in the biliary concentration and secretion rates of total, reduced and oxidized glutathione. When the rats were treated with cyclosporine A for 1 week, at a dose of 10 mg/kg per day, similar cholestatic and inhibitory effects on the biliary secretion of glutathione were noted both before and after the intrabiliary catabolism of the tripeptide had been inhibited with acivicin; in addition, the hepatic content of glutathione was also reduced. The cholestatic effect of the drug was associated with reductions in the four bile flow fractions evaluated: bile acid- and glutathione-dependent bile flow and bile acid- and glutathione-independent bile flow. CONCLUSIONS These findings indicate that cyclosporine-induced cholestasis in the rat is due not only to alterations in the hepatobiliary transport of bile acids but also to an impairment of bile formation dependent on the biliary secretion of glutathione, possibly through inhibition of the canalicular transport of the tripeptide.

Abstract
Paraquat is a pneumotoxin that causes lung injury by enhancing oxidative stress; however, the cellular responses to these redox events are undefined. We previously showed that paraquat produced selective peroxidation of phosphatidylserine that preceded apoptosis in 32D cells. We now report that the phospholipase A2 (PLA2) inhibitor quinacrine can attenuate phosphatidylserine oxidation and also block paraquat-induced apoptosis. Therefore, we investigated the potential for PLA2 to mediate apoptosis after paraquat. We found that, in contrast to quinacrine, the PLA2 inhibitors manoalide, aristolochic acid, and arachidonyl trifluoromethylketone failed to prevent paraquat-induced apoptosis. Moreover, no evidence of PLA2 activation was observed within 7 h after paraquat exposure. Finally, quinacrine failed to inhibit basal and 4-bromo-A-23187-induced release of [3H]arachidonic acid at concentrations that protected paraquat-induced apoptosis. We conclude that paraquat-induced phosphatidylserine oxidation and apoptosis occurred in the absence of PLA2 activation and that quinacrine protected phosphatidylserine and cell viability after paraquat in a PLA2-independent manner.
