Abstract
Paediatric patients with relapsed B cell acute lymphoblastic leukaemia (B-ALL) have poor prognosis, as relapse-causing clones are often refractory to common chemotherapeutics. While the molecular mechanisms leading to chemoresistance are varied, significant evidence suggests interactions between B-ALL blasts and cells within the bone marrow microenvironment modulate chemotherapy sensitivity. Importantly, bone marrow mesenchymal stem cells (BM-MSCs) and BM adipocytes are known to support B-ALL cells through multiple distinct molecular mechanisms. This review discusses the contribution of integrin-mediated B-ALL/BM-MSC signalling and asparagine supplementation in B-ALL chemoresistance. In addition, the role of adipocytes in sequestering anthracyclines and generating a BM niche favourable for B-ALL survival is explored. Furthermore, this review discusses the role of BM-MSCs and adipocytes in promoting a quiescent and chemoresistant B-ALL phenotype. Novel treatments which target these mechanisms are discussed herein, and are needed to improve dismal outcomes in patients with relapsed/refractory disease.

Abstract
Leukaemia is a malignant disease of the blood. Current treatments for leukaemia are associated with serious side-effects. Plant-derived polyphenols have been identified as potent anti-cancer agents and have been shown to work synergistically with standard chemotherapy agents in leukaemia cell lines. Polyphenols have multiple mechanisms of action and have been reported to decrease cell proliferation, arrest cell cycle and induce apoptosis via the activation of caspase (3, 8 and 9); the loss of mitochondrial membrane potential and the release of cytochrome c. Polyphenols have been shown to suppress activation of transcription factors, including NF-kB and STAT3. Furthermore, polyphenols have pro-oxidant properties, with increasing evidence that polyphenols inhibit the antioxidant activity of glutathione, causing oxidative DNA damage. Polyphenols also induce autophagy-driven cancer cell death and regulate multidrug resistance proteins, and thus may be able to reverse resistance to chemotherapy agents. This review examines the molecular mechanism of action of polyphenols and discusses their potential therapeutic targets. Here, we discuss the pharmacological properties of polyphenols, including their anti-inflammatory, antioxidant, anti-proliferative, and anti-tumour activities, and suggest that polyphenols are potent natural agents that can be useful therapeutically; and discuss why data on bioavailability, toxicity and metabolism are essential to evaluate their clinical use.

Abstract
Viruses have developed strategies to counteract the apoptotic response of the infected host cells. Modulation of apoptosis is also thought to be a major component of viral persistence and progression to leukemia induced by retroviruses like human T-lymphotropic virus type 1 (HTLV-1) and bovine leukemia virus (BLV). Here, we analyzed the mechanism of ex vivo apoptosis occurring after isolation of peripheral blood mononuclear cells from BLV-infected sheep. We show that spontaneous apoptosis of ovine B lymphocytes requires at least in part a caspase 8-dependent pathway regardless of viral infection. Cell death is independent of cytotoxic response and does not involve the tumor necrosis factor alpha/NF-kappaB/nitric oxide synthase/cyclooxygenase pathway. In contrast, pharmaceutical depletion of reduced glutathione (namely, gamma-glutamyl-l-cysteinyl-glycine [GSH]) by using ethacrynic acid or 1-pyrrolidinecarbodithioic acid specifically reverts inhibition of spontaneous apoptosis conferred indirectly by protective BLV-conditioned media; inversely, exogenously provided membrane-permeable GSH-monoethyl ester restores cell viability in B lymphocytes of BLV-infected sheep. Most importantly, intracellular GSH levels correlate with virus-associated protection against apoptosis but not with general inhibition of cell death induced by polyclonal activators, such as phorbol esters and ionomycin. Finally, inhibition of apoptosis does not correlate with the activities of GSH peroxidase and GSH reductase. In summary, our data fit into a model in which modulation of the glutathione system is a key event involved in indirect inhibition of apoptosis associated with BLV. These observations could have decisive effects during therapeutic treatment of delta-retroviral pathogenesis.

Abstract
Improvements in the traditional glutathione (GSH)-reductase recycling method for determining total glutathione levels in adherent growing cells have been achieved by eliminating the direct use of expensive nicotinamide adenine dinucleotide phosphate (NADPH) and normalizing the levels of GSH to moles/liter instead of the more usual but more error-prone method of normalizing with cellular protein. A glucose-6-phosphate-dehydrogenase auxiliary reaction has been added to the microtiter-adapted enzyme method of Tietze; thus NADP(+) and glucose-6-phosphate replace NADPH in the method. This modification lowers the possibility for substrate inhibition of the reductase by high levels of NADPH during the initial phase of the reaction while at the same time reducing the assay costs by 75-85%. To calculate the cellular concentration of GSH, the number of cells used for the GSH determination, estimated by counting cell nuclei of benzalkonium chloride-lysed cells with a Coulter Counter Z2, and the average cell volume, also determined with the Coulter Counter, are multiplied to give the total sample volume. The quotient of the amount of GSH found in the cells and the total sample volume yields the GSH concentration in moles/liter. The assay has been validated with respect to precision (+/-2.6%), relative accuracy (-4.2 %), linearity (r(2)=0.98), linear range (0.5-10 microM), and limit of detection (80 pmol). Recovery was cell line dependent and ranged between 70 and 103% in the six cell lines. As an application of this method, the GSH concentrations in six human cancer cell lines were determined, without and with a 24-h preincubation with 200 microM D,L-buthionine-S,R-sulfoximine (BSO), an inhibitor of GSH biosynthesis. As expected, BSO lowered GSH levels on the average 85%.

Abstract
Glucocorticoids remain among the most important drugs in the treatment of acute lymphoblastic leukemia (ALL). Although the mechanisms of glucocorticoid resistance have been studied in some T-cell leukemic cell lines, less work has been done with B-cell lines. We established a dexamethasone (DEX)-resistant human pre-B lineage leukemia cell line (697/DEX) and investigated the mechanism of resistance. 697/DEX was over 430-fold more resistant to DEX compared with the parental cells (697/Neo). Overexpression of Bcl-2 protein was not observed in 697/DEX, different from the mechanism of resistance in Bcl-2-virus-infected cells (697/Bcl-2). Although the expression of p-glycoprotein (Pgp) in 697/DEX was positive, its functional activity was not detected. The numbers of glucocorticoid receptors (GR) in 697/DEX and 697/Bcl-2 were significantly lower than those in 697/Neo. In addition, 697/DEX and 697/Bcl-2 had higher levels of glutathione (GSH) than 697/Neo. In the presence of L-buthionine-(S, R)-sulfoximine (BSO), an inhibitor of GSH synthesis, both 697/DEX and 697/Bcl-2 recovered their sensitivity to DEX. Interestingly, cell death by the depletion of GSH did not involve caspase-3/7 activation in 697/Bcl-2 and 697/DEX, different from 697/Neo, suggesting a death mechanism through caspase-independent programmed cell death or necrosis. In conclusion, DEX-resistance in 697/DEX was related not only to a GR decrease, but also to an increase in intracellular GSH level in the DEX-resistant B-cell leukemia cell line. Circumvention of DEX-resistance with BSO may offer an approach to overcoming resistance to chemotherapy in B-cell lineage ALL.

Mitochondrial membrane sensitivity to depolarization in acute myeloblastic leukemia is associated with spontaneous in vitro apoptosis, wild-type TP53, and vicinal thiol/disulfide status.

Abstract
Nonresponse to remission-induction chemotherapy, which remains a major problem in acute myeloblastic leukemia (AML), has been linked to cellular resistance to apoptosis. Because the apoptosis induced by chemotherapeutic drugs is mediated by loss of mitochondrial transmembrane potential (MTP), it was postulated that sensitivity to mitochondrial membrane depolarization might be heterogeneous in AML. Using the uncoupling agent carbonyl cyanide m-chlorophenylhydrazone (mClCCP), the mitochondrial membrane sensitivity to depolarization (mClCCP concentrations that inhibit 50% of the transmembrane potential [IC(50)]) in AML blasts was measured and demonstrated marked interclonal heterogeneity, with the existence of comparatively sensitive (median mClCCP IC(50), 4 microM) and resistant (median mClCCP IC(50), 10 microM) clones. Furthermore, the mClCCP IC(50) was inversely associated with spontaneous in vitro apoptosis (P =.001). It was high in cases with mutant TP53 and correlated with the total cellular level of the multidrug resistance-associated protein (P =.019) but not of bcl-2, bax, or bcl-x. It was also found that the dithiol oxidant diamide, in contrast to the monovalent thiol oxidant diethyl maleate, increased the sensitivity of mitochondrial membranes to mClCCP. To confirm that TP53 directly affects MTP in leukemic cells and to establish the role of vicinal thiol oxidation in the TP53-dependent pathway, CEM 4G5 leukemia cells with forced, temperature-dependent expression of TP53 were studied. Monobromobimane, which inhibits mitochondrial membrane depolarization by preventing dithiol cross-linking, inhibited depolarization and apoptosis in 4G5 cells. It was concluded that in leukemia, TP53 and vicinal thiol/disulfide status are determinants of mitochondrial membrane sensitivity to depolarization, which is in turn associated with spontaneous apoptosis.

Abstract
A preliminary study has linked raised blast glutathione levels with chemoresistance in acute myeloid and lymphoblastic leukemia in adults and children. In this study, therefore, the relationship between leukemic blast glutathione levels and prognosis in childhood acute lymphoblastic leukemia (ALL) was investigated. A total of 77 childhood ALL samples were analyzed, 62 at initial presentation and 15 at relapse. A 20-fold interindividual variation in glutathione levels at presentation (median, 6.54 nmol/mg protein; range, 1.37 to 27.9) was demonstrated. The median level in T-lineage ALL was 2. 3-fold higher than in B-lineage ALL (Mann-Whitney test, P <.0001). There was a significant correlation between presenting white cell count (WBC) and glutathione level (Spearman rank correlation coefficient, rho = 0.45, P =.001). A high DNA index correlated with low glutathione levels (Mann-Whitney test, P =.013). There was no significant relationship between glutathione levels and in vitro drug sensitivity. Patients with glutathione levels above the median had a significantly greater risk of relapse (log-rank test statistic, 5.55; P =.018), and the overall survival rate was significantly reduced (log-rank test statistic, 4.38; P =.04). Multivariate analysis demonstrated that glutathione concentration was of independent prognostic value when assessed in conjunction with age, gender, WBC, and immunophenotype. The association of elevated blast glutathione levels with an increased risk of relapse suggests that glutathione-depleting agents may be of therapeutic value in patients who present with a high WBC.
