Rainey NE, Armand AS, Petit PX. Sodium arsenite and arsenic trioxide differently affect the oxidative stress of lymphoblastoid cells: An intricate crosstalk between mitochondria, autophagy and cell death. PLoS One 2024; 19:e0302701. [PMID: 38728286 PMCID: PMC11086853 DOI: 10.1371/journal.pone.0302701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Accepted: 04/10/2024] [Indexed: 05/12/2024] Open
Abstract
Although the toxicity of arsenic depends on its chemical forms, few studies have taken into account the ambiguous phenomenon that sodium arsenite (NaAsO2) acts as a potent carcinogen while arsenic trioxide (ATO, As2O3) serves as an effective therapeutic agent in lymphoma, suggesting that NaAsO2 and As2O3 may act via paradoxical ways to either promote or inhibit cancer pathogenesis. Here, we compared the cellular response of the two arsenical compounds, NaAsO2 and As2O3, on the Burkitt lymphoma cell model, the Epstein Barr Virus (EBV)-positive P3HR1 cells. Using flow cytometry and biochemistry analyses, we showed that a NaAsO2 treatment induces P3HR1 cell death, combined with drastic drops in ΔΨm, NAD(P)H and ATP levels. In contrast, As2O3-treated cells resist to cell death, with a moderate reduction of ΔΨm, NAD(P)H and ATP. While both compounds block cells in G2/M and affect their protein carbonylation and lipid peroxidation, As2O3 induces a milder increase in superoxide anions and H2O2 than NaAsO2, associated to a milder inhibition of antioxidant defenses. By electron microscopy, RT-qPCR and image cytometry analyses, we showed that As2O3-treated cells display an overall autophagic response, combined with mitophagy and an unfolded protein response, characteristics that were not observed following a NaAsO2 treatment. As previous works showed that As2O3 reactivates EBV in P3HR1 cells, we treated the EBV- Ramos-1 cells and showed that autophagy was not induced in these EBV- cells upon As2O3 treatment suggesting that the boost of autophagy observed in As2O3-treated P3HR1 cells could be due to the presence of EBV in these cells. Overall, our results suggest that As2O3 is an autophagic inducer which action is enhanced when EBV is present in the cells, in contrast to NaAsO2, which induces cell death. That's why As2O3 is combined with other chemicals, as all-trans retinoic acid, to better target cancer cells in therapeutic treatments.

A drug potency signature links progression of chronic lymphocytic leukemia to mitochondria-related stress responses and metabolic reprogramming under hypoxia. Toxicol Appl Pharmacol 2020; 398:115016. [PMID: 32325063 DOI: 10.1016/j.taap.2020.115016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Revised: 04/15/2020] [Accepted: 04/17/2020] [Indexed: 11/23/2022]
Abstract
Chronic lymphocytic leukemia (CLL) cells change their metabolic program between normoxia and hypoxia, possibly affecting cytotoxic drug potency by altering mitochondria-related cell stress responses (MRCSR) including mitophagy, mitochondrial biogenesis, and mitochondrial proteostasis. We evaluated in CLL cells from nine patients, the single and multiple-combined drug potency of arsenic trioxide (ATO), valproic acid (VPA), vincristine (VCR) and MG132 as four pharmacological sensors influencing mitochondrial apoptosis, mitochondrial biogenesis, mitophagy, and mitochondrial proteostasis respectively, under normoxia and hypoxia to force hypoxia-induced metabolic reprogramming (HMR). Untreated cells from all patients remained viable under O2 levels below 0.5% for 72 h. We obtained 21 measures of drug potency and interaction at 50% effect level that we denoted drug potency signature (DPS). Using the comparative DPS between normoxia and hypoxia, two non-supervised classification algorithms discriminated CLL patients with active disease (ADT) and stable disease (NAD) and showed complete consistency with their clinical characteristics. In ADT group under hypoxia, the potency of MG132 was increased, the interaction of ATO + VPA and ATO + VPA + VCR shifted towards antagonism, and ATO + VPA + VCR + MG132 shifted towards synergism, indicating a prominent role of mitochondrial proteostasis. Classification of patients based on DPS, depended on the contrasting response of drugs under hypoxia and normoxia, owing to HMR. Using these drugs as pharmacological sensors, we linked the metabolic arrangement of CLL cells under hypoxia, to potency of drugs targeting MRCSR, and to the clinical features of individual patients, therefore providing new sources of data on disease progression, drug response and risk prognosis.

In vitro anti-inflammatory properties of Smilax campestris aqueous extract in human macrophages, and characterization of its flavonoid profile. JOURNAL OF ETHNOPHARMACOLOGY 2020; 247:112282. [PMID: 31604138 DOI: 10.1016/j.jep.2019.112282] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/31/2019] [Revised: 09/18/2019] [Accepted: 10/07/2019] [Indexed: 05/20/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Extracts of Smilax campestris Griseb (Smilacaceae) have been employed in the treatment of several inflammatory diseases as a traditional herbal medicine. However, the cellular and molecular mechanisms involved in the observed effects remain elusive. Macrophages are known to play a central role in inflammatory responses. These cells are activated in response to a diversity of danger signals and produce several mediators of inflammation that eventually regulate the immune response. For all the above mentioned, scientific evidence is required to support the popular use of S. campestris. AIM OF THE STUDY We aimed to investigate the anti-inflammatory effect of S. campestris aqueous extract (SME) in activated THP-1 human macrophages, on the production of some mediators of inflammation and oxidative stress in order to provide scientific support for its popular use. MATERIALS AND METHODS The characterization of SME was assessed by HPLC-MS/MS. The production of the pro-inflammatory cytokines and chemokines was evaluated by ELISA. The activity of metalloproteases was evaluated by zymography. The subcellular localization of the NF-κB transcription factor was analysed by Western blot. The superoxide anion and glutathione levels were assessed by flow cytometry. The cytotoxicity induced by SME in THP-1 macrophages was also investigated by the LDH release test. RESULTS In the present study, we have identified catechin and glycosylated derivatives of quercetin (quercetin-3-O-glucoside, quercetin-3-O-galactoside, rutin and quercetin-3-rhamnoside) as major components of the aqueous SME. We found that SME significantly decreased the production of the pro-inflammatory cytokines tumour necrosis factor (TNF)- α, interleukin (IL)-1β, IL-6, IL-8 and monocyte chemoattractant protein (MCP)-1 and the activity of the metalloproteinase (MMP)-9, in lipopolysaccharide-activated macrophages derived from the monocytic cell line THP-1. Furthermore, SME diminished the expression of NF-κB p65 subunit in the nuclear fraction. In addition, SME decreased the production of superoxide anion in THP-1 macrophages, without altering the levels of reduced glutathione. CONCLUSION These results suggest that SME exerts its anti-inflammatory effects in human activated macrophages by inhibiting the production of pro-inflammatory cytokines, matrix metalloproteinases and the NF-κB transcription factor pathway along with a reduction of oxidative stress mediators. Moreover, catechin and glycosylated derivatives of were identified by HPLC-MS/MS in SME. Our findings provide scientific support for the traditional use of the S. campestris extracts.

Abstract
The replication-dependent histone genes are the only metazoan genes whose messenger RNA (mRNA) does not terminate with a poly(A) tail at the 3'-end. Instead, the histone mRNAs display a stem-loop structure at their 3'-end. Stem-loop-binding protein (SLBP) binds the stem-loop and regulates canonical histone mRNA metabolism. Here we report that exposure to arsenic, a carcinogenic metal, decreased cellular levels of SLBP by inducing its proteasomal degradation and inhibiting SLBP transcription via epigenetic mechanisms. Notably, arsenic exposure dramatically increased polyadenylation of canonical histone H3.1 mRNA possibly through down-regulation of SLBP expression. The polyadenylated H3.1 mRNA induced by arsenic was not susceptible to normal degradation that occurs at the end of S phase, resulting in continued presence into mitosis, increased total H3.1 mRNA, and increased H3 protein levels. Excess expression of canonical histones have been shown to increase sensitivity to DNA damage as well as increase the frequency of missing chromosomes and induce genomic instability. Thus, polyadenylation of canonical histone mRNA following arsenic exposure may contribute to arsenic-induced carcinogenesis.

MG132-mediated inhibition of the ubiquitin-proteasome pathway ameliorates cancer cachexia. J Cancer Res Clin Oncol 2013; 139:1105-15. [PMID: 23535871 PMCID: PMC7087863 DOI: 10.1007/s00432-013-1412-6] [Citation(s) in RCA: 47] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2013] [Accepted: 02/28/2013] [Indexed: 01/06/2023]
Abstract
Purpose To evaluate the effect of proteasome inhibitor MG132 in cancer cachexia and to delineate the molecular mechanism underlying. Methods We established an experimental cancer cachexia model by subcutaneously implanting colon 26 cells into the armpits of BALB/c mice. Following administration of MG132 at various time points, body weight, food intake, gastrocnemius muscle weight, spontaneous activity and survival of tumor-bearing mice were examined along with tumor growth. Moreover, cachectic markers including glucose, triglyceride, albumin and total proteins as well as levels of the proinflammatory cytokines TNF-α and IL-6 in serum and gastrocnemius tissue were measured. Finally, mRNA and protein levels of p65, IκBα, and ubiquitin E3 ligases MuRF1 and MAFbx in gastrocnemius muscle were assessed. Results MG132 treatment significantly alleviated cancer cachexia as demonstrated by attenuated weight loss, altered carbohydrate metabolism and muscle atrophy and increased spontaneous activity and survival time of tumor-bearing mice. MG132 reduced tumor growth and the levels of TNF-α and IL-6 in serum and gastrocnemius tissue. NF-κB, MuRF1 and MAFbx were also inhibited by MG132. Unexpectedly, MG132 was more efficient when administrated during the early stages of cachexia. MG132 had no effect on food intake of tumor-bearing mice. Conclusion Our results demonstrate that MG132-induced inhibition of the ubiquitin–proteasome pathway in cancer cachexia decreased the activity of NF-κB and the degradation of IκBα, and reduced the levels of TNF-α and IL-6 in serum and gastrocnemius tissue, accompanied by downregulation of MuRF1 and MAFbx. These data suggest that MG132 is a potential therapeutic and preventive agent for cancer cachexia.

Abstract
The ability to modulate balance between cell survival and death is recognized for its great therapeutic potential. Therefore, research continues to focus on elucidation of cell machinery and signaling pathways that control cell proliferation and apoptosis. Conventional chemotherapeutic agents often have a cytostatic effect over tumor cells. New natural or synthetic chemotherapeutic agents have a wider spectrum of interesting antitumor activities that merit in-depth studies. In the present work, we aimed at characterizing the molecular mechanism leading to induction of cell death upon treatment of the lymphoblastoid cell line PL104 with caffeic acid phenylethyl ester (CAPE), MG132 and two conventional chemotherapeutic agents, doxorubicine (DOX) and vincristine (VCR). Our results showed several apoptotic hallmarks such as phosphatidylserine (PS) exposure on the outer leaflet of the cell membrane, nuclear fragmentation, and increase sub-G1 DNA content after all treatments. In addition, all four drugs downregulated survivin expression. CAPE and both chemotherapeutic agents reduced Bcl-2, while only CAPE and MG132 significantly increased Bax level. CAPE and VCR treatment induced the collapse of mitochondrial membrane potential (∆ψm). All compounds induced cytochrome c release from mitochondrial compartment to cytosol. However, only MG132 caused the translocation of Smac/DIABLO. Except for VCR treatment, all other drugs increased reactive oxygen species (ROS) production level. All treatments induced activation of caspases 3/7, but only CAPE and MG132 led to the activation of caspase 9. In conclusion, our results indicate that CAPE and MG132 treatment of PL104 cells induced apoptosis through the mitochondrial intrinsic pathway, whereas the apoptotic mechanism induced by DOX and VCR may proceed through the extrinsic pathway.
