JOURNAL OF PHARMACY AND BIOALLIED SCIENCES 2023; 15:15-20. [PMID: 37313537 PMCID: PMC10259734 DOI: 10.4103/jpbs.jpbs_50_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 02/04/2023] [Accepted: 02/16/2023] [Indexed: 06/15/2023] Open
Abstract
Background The ATP-Binding Cassette (ABC) transporter has long been studied to confer drug resistance in human tumors and play important role in metabolic processes and cellular signaling. The overexpression of ABCB1, ABCC1, ABCC2, ABCC3, and ABCG2 leads to decreased sensitivity of lung cancer to cisplatin. At the transcription level, the expression of ABC transporters is highly regulated and requires the complex interplay of factors involved in differentiation and development, cell survival and apoptosis upon intrinsic and environmental stress. The p53 regulation of drug-resistance genes is also complex yet not well understood. Previously, we demonstrated the synergistic interaction between bixin or fucoxanthin with cisplatin in A549 lung cancer cells. Objectives Current study aims to identify whether carotenoids enhancing therapeutic effect of Cisplatin due to the ability to reverse drug resistance associated proteins, such as ABC transporter and regulating the tumor suppressor corresponding gene, p53. Methods Real-Time Quantitative-Polymerase Chain Reaction (RT-qPCR) was performed to estimate the expression level of ABCC1 and ABCC2, and p53 of A549 cell lines in response to carotenoids alone and in combination with cisplatin. Results and Conclusion The administration of bixin or fucoxanthin decreases the expression of ABCC1 and ABCC2. Both carotenoids, either alone or in combination with cisplatin, upregulated p53 gene expression indicating the mechanism of proliferation inhibition and apoptosis occurs via the p53 caspase-independent pathway.

Multidrug Resistance Like Protein 1 Activity in Malpighian Tubules Regulates Lipid Homeostasis in Drosophila. MEMBRANES 2021; 11:membranes11060432. [PMID: 34201304 PMCID: PMC8229909 DOI: 10.3390/membranes11060432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 05/30/2021] [Accepted: 06/05/2021] [Indexed: 11/16/2022]
Abstract
Simple Summary Multidrug resistance proteins (MRPs) are important for ion transport, toxin/xenobiotic secretion, and signal transduction. Although studies have been undertaken to understand their physiological function, it is not fully known how MRPs may regulate metabolism. We knocked down the expression of Drosophila multidrug-resistance like protein 1 (MRP) in several tissues central to metabolic regulation. Reducing MRP in Malpighian tubules, the functional equivalent to the human kidney, was sufficient to disrupt metabolic homeostasis, owing to abnormal lipid accumulation, as well as changes in feeding behavior. It also increased oxidative stress resistance in adult flies, possibly due to reduced levels of reactive oxygen species. Abstract Multidrug resistance proteins (MRPs), members of the ATP-binding cassette transporter (ABC transporter) family, are pivotal for transporting endo- and xenobiotics, which confer resistance to anticancer agents and contribute to the clearance of oxidative products. However, their function in many biological processes is still unclear. We investigated the role of an evolutionarily conserved MRP in metabolic homeostasis by knocking down the expression of Drosophila multidrug-resistance like protein 1 (MRP) in several tissues involved in regulating metabolism, including the gut, fat body, and Malpighian tubules. Interestingly, only suppression of MRP in the Malpighian tubules, the functional equivalent to the human kidney, was sufficient to cause abnormal lipid accumulation and disrupt feeding behavior. Furthermore, reduced Malpighian tubule MRP expression resulted in increased Hr96 (homolog of human pregnane X receptor) expression. Hr96 is known to play a role in detoxification and lipid metabolism processes. Reduced expression of MRP in the Malpighian tubules also conveyed resistance to oxidative stress, as well as reduced normal levels of reactive oxygen species in adult flies. This study reveals that an evolutionarily conserved MRP is required in Drosophila Malpighian tubules for proper metabolic homeostasis.

EJNMMI Res 2021; 11:9. [PMID: 33492449 PMCID: PMC7835267 DOI: 10.1186/s13550-021-00752-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2020] [Accepted: 01/11/2021] [Indexed: 11/30/2022] Open
Abstract
Background [18F]Fluoromisonidazole ([18F]FMISO) is a PET imaging probe widely used for the detection of hypoxia. We previously reported that [18F]FMISO is metabolized to the glutathione conjugate of the reduced form in hypoxic cells. In addition, we found that the [18F]FMISO uptake level varied depending on the cellular glutathione conjugation and excretion ability such as enzyme activity of glutathione-S-transferase and expression levels of multidrug resistance-associated protein 1 (MRP1, an efflux transporter), in addition to the cellular hypoxic state. In this study, we evaluated whether MRP1 activity affected [18F]FMISO PET imaging. Methods FaDu human pharyngeal squamous cell carcinoma cells were pretreated with MRP1 inhibitors (cyclosporine A, lapatinib, or MK-571) for 1 h, incubated with [18F]FMISO for 4 h under hypoxia, and their radioactivity was then measured. FaDu tumor-bearing mice were intravenously injected with [18F]FMISO, and PET/CT images were acquired at 4 h post-injection (1st PET scan). Two days later, the same mice were pretreated with MRP1 inhibitors (cyclosporine A, lapatinib, or MK-571) for 1 h, and PET/CT images were acquired (2nd PET scan). Results FaDu cells pretreated with MRP1 inhibitors exhibited significantly higher radioactivity than those without inhibitor treatment (cyclosporine A: 6.91 ± 0.27, lapatinib: 10.03 ± 0.47, MK-571: 10.15 ± 0.44%dose/mg protein, p < 0.01). In the in vivo PET study, the SUVmean ratio in tumors [calculated as after treatment (2nd PET scan)/before treatment of MRP1 inhibitors (1st PET scan)] of the mice treated with MRP1 inhibitors was significantly higher than those of control mice (cyclosporine A: 2.6 ± 0.7, lapatinib: 2.2 ± 0.7, MK-571: 2.2 ± 0.7, control: 1.2 ± 0.2, p < 0.05). Conclusion In this study, we revealed that MRP1 inhibitors increase [18F]FMISO accumulation in hypoxic cells. This suggests that [18F]FMISO-PET imaging is affected by MRP1 inhibitors independent of the hypoxic state.

Abstract
Hypoxia in tumor tissues plays a pivotal role in tumor progression and angiogenesis, and is associated with cancer therapeutic resistance. For the diagnosis of hypoxia, non-invasive imaging techniques, especially positron emission tomography (PET) with 2-nitroimidazole-based probes, are used, since 2-nitroimidazole-based probes are considered to undergo reductive metabolism on their 2-nitroimidazole moiety and become trapped in hypoxic cells. However, the detailed mechanism of their accumulation remains unclear because of the difficulty in estimating the metabolites by radioisotopic analysis. Imaging mass spectrometry (IMS) can distinguish the distribution patterns of the drug and its metabolites. To clarify the accumulation mechanism of 2-nitroimidazole-based probes in hypoxic cells, we evaluated [18F]fluoromisonidazole (FMISO), a 2-nitroimidazole-based PET probe, in combination with radioisotopic analysis and IMS. We found that the glutathione conjugate of reduced FMISO (amino-FMISO-GS) was the main FMISO metabolite, and was specifically distributed in the hypoxic regions of tumors. The same phenomenon was observed when we examined another 2-nitroimidazole-based probe, pimonidazole. The in vitro cellular uptake study revealed that FMISO accumulation in hypoxic cells depends on the cell type. In those cells exhibiting higher FMISO uptake, the reactive glutathione level and enzyme (glutathione S-transferase; GST) activity catalyzing the glutathione conjugation reaction was significantly higher, whereas the expression level of the efflux transporter (multidrug resistance-associated protein 1; MRP1) was significantly lower. Our study suggests that 2-nitroimidazole-based probes accumulate in hypoxic cells via glutathione conjugation following reductive metabolism, which depends not only on the glutathione conjugation capacity of the cells but also on hypoxic conditions.

Abstract
OBJECTIVE 18F-fluoromisonidazole (FMISO), a well-known PET imaging probe for diagnosis of hypoxia, is believed to accumulate in hypoxic cells via covalent binding with macromolecules after reduction of the nitro group. Previously, we showed the majority of 18F-FMISO was incorporated into low-molecular-weight metabolites in hypoxic tumors, and the glutathione conjugate of reduced FMISO (amino-FMISO-GS) distributed in the tumor hypoxic regions as revealed by imaging mass spectrometry (IMS). The present study was conducted to clarify whether FMISO is metabolized to amino-FMISO-GS within tumor cells and how amino-FMISO-GS contributes to FMISO accumulation in hypoxic cells. We also evaluated the relationship between FMISO accumulation and the glutathione conjugation-related factors in the cells. METHODS Tumor cells (FaDu, LOVO, and T24) were treated with 18F-FMISO and incubated under normoxic or hypoxic conditions for 4 h. The FMISO metabolites were analyzed with LC-ESI-MS. Several glutathione conjugation-related factors of tumor cells were evaluated in vitro. FaDu tumor-bearing mice were intravenously injected with 18F-FMISO and the tumors were excised at 4 h post-injection. Autoradiography, IMS and histologic studies were performed. RESULTS Amino-FMISO-GS was the main contributor to FMISO incorporated in hypoxic FaDu cells in vitro and in vivo. Total FMISO uptake levels and amino-FMISO-GS levels were highest in FaDu, followed by LOVO, and then T24 (total uptake: 0.851 ± 0.009 (FaDu), 0.617 ± 0.021 (LOVO) and 0.167 ± 0.006 (T24) % dose/mg protein; amino-FMISO-GS: 0.502 ± 0.035 (FaDu), 0.158 ± 0.013 (LOVO), and 0.007 ± 0.001 (T24) % dose/mg protein). The glutathione level of FaDu was significantly higher than those of LOVO and T24. The enzyme activity of glutathione-S-transferase catalyzing the glutathione conjugation reaction in FaDu was similar levels to that in LOVO, and was higher than that in T24. Quantitative RT-PCR analysis revealed that the expression levels of efflux transporters of the glutathione conjugate (multidrug resistance-associated protein 1) were lowest in FaDu, followed by LOVO, and then T24. CONCLUSIONS FMISO accumulates in hypoxic cells through reductive metabolism followed by glutathione conjugation. We illustrated the possibility that increased production and decreased excretion of amino-FMISO-GS contribute to FMISO accumulation in tumor cells under hypoxic conditions.

Abstract
Chemotherapy is one of the main strategies for cancer treatment, but its effective application is seriously limited by the development of drug resistance. In this study, we designed micellar vectors for doxorubicin based on amphiphilic copolymers sequentially linking β-cyclodextrin (β-CD), polylacticacid (PLA) or polycaprolactone (PCL) block, and polyethylene glycol (PEG) block to overcome drug resistance in human acute myeloid leukemia cells (HL60/ADR) overexpressing multidrug resistance protein 1 (MRP1). The significant enhancement in cytotoxicity and inhibited HL60/ADR tumor growth in mouse was achieved. More importantly, several analyses were performed to understand the interactions between various polymers and MRP1 at the cellular level. The results showed that the polymers did not show remarkable correlation of MRP1 gene and protein expression, but could decrease intracellular ATP, mitochondrial membrane potential and glutathione levels, which was greatly dependent on the molecular structure of polymers. In conclusion, these novel micelles can be considered as a kind of promising drug delivery system for tumor therapy to reverse drug resistance related to MRP1 overexpression.

Glutathione import in Haemophilus influenzae Rd is primed by the periplasmic heme-binding protein HbpA. Proc Natl Acad Sci U S A 2010; 107:13270-5.

Abstract
Glutathione (GSH) is a vital intracellular cysteine-containing tripeptide across all kingdoms of life and assumes a plethora of cellular roles. Such pleiotropic behavior relies on a finely tuned spatiotemporal distribution of glutathione and its conjugates, which is not only controlled by synthesis and breakdown, but also by transport. Here, we show that import of glutathione in the obligate human pathogen Haemophilus influenzae, a glutathione auxotrophe, is mediated by the ATP-binding cassette (ABC)-like dipeptide transporter DppBCDF, which is primed for glutathione transport by a dedicated periplasmic-binding protein (PBP). We have identified the periplasmic lipoprotein HbpA, a protein hitherto implicated in heme acquisition, as the cognate PBP that specifically binds reduced (GSH) and oxidized glutathione (GSSG) forms of glutathione with physiologically relevant affinity, while it exhibits marginal binding to hemin. Dissection of the ligand preferences of HbpA showed that HbpA does not recognize bulky glutathione S conjugates or glutathione derivatives with C-terminal modifications, consistent with the need for selective import of useful forms of glutathione and the concomitant exclusion of potentially toxic glutathione adducts. Structural studies of the highly homologous HbpA from Haemophilus parasuis in complex with GSSG have revealed the structural basis of the proposed novel function for HbpA-like proteins, thus allowing a delineation of highly conserved structure-sequence fingerprints for the entire family of HbpA proteins. Taken together, our studies unmask the main physiological role of HbpA and establish a paradigm for glutathione import in bacteria. Accordingly, we propose a name change for HbpA to glutathione-binding protein A.

Abstract
[35S]S-[5-(4-benzoylphenyl)pentyl]glutathione (GIF-0017) as a biochemical probe targeting the ATP-dependent organic anion transporters GS-X pumps was synthesized by the reaction of [35S]glutathione and excess 4-(5-bromo)pentylbenzophenone under alkaline conditions, with the radiochemical yield of 24-33% after HPLC purification. Photolysis of the mixture of [35S]GIF-0017 and plasma membrane vesicles prepared from the MRP1 cDNA-transfected LLC-PK1 cells resulted in radio-labeling of a 180-kDa membrane protein. Immunoprecipitation and western blotting using an anti-MRP1 monoclonal antibody confirmed that the [35S]GIF-0017-labeled protein was the MRPI/GS-X pump.
