Abstract
Combination pharmacotherapy is becoming increasingly necessary because most diseases are pathophysiologically controlled at the subcellular level by target proteins in a combinatorial manner. We demonstrate the application of the stimulus-response mechanistic model in characterising the drug and physiological properties of pharmacodynamic drug-drug interactions (PDDI) using previously published in vitro and in vivo drug combination experiments. The in vitro experiment tested the effect of a combination of SCH66336 and 4-HPR on the survival of in squamous cell carcinoma cell lines, while the in vivo experiment tested the effect of a combination of cetuximab and cisplatin on tumour growth inhibition in female xenograft mice. The model adequately described both experiments, quantified both system and drug properties and predicted the nature of the PDDI mechanism. Strong baseline signals of 7.35 and 610 units existed in the in vitro and in vivo experiments respectively. An overall synergistic relationship (interaction index = 1.03E-8) was detected in the in vitro experiment. In the in vivo model, the overall interaction index was 70,139.45 implying an antagonistic interaction between the cisplatin and the cetuximab signals.

Abstract
The aim of the study is to investigate the anti-tumor effect of Bifidobacterium infantis 35624 in a xenograft model in BALB/c mice injected with 4T1 cells as a support for chemotherapeutic treatments of doxorubicin in vivo. The MTT assay was used to determine the cytotoxicity of doxorubicin against cancer cells, and apoptosis was analyzed by using flow cytometry. 4T1 cells (2 × 104 cells/mouse) were injected to BALB/c mice, and mice were fed with/without gavage B. infantis milk (108 CFU/mL) for 14 days and treated with doxorubicin on 5th and 10th days. The weights of the mice were recorded during the study, and the tumor sizes were measured by caliper at the 14th day. CD8 + T cell response was analyzed by using flow cytometer, and the results were compared to control and tumor control groups. The IC50 value for doxorubicin on 4T1 cell lines was determined as 0.053 ± 0.012 µg/mL. The apoptotic effect of doxorubicin at IC50 concentration was determined as 82.3% of cells to late apoptosis, 3.6% of cells to pro-apoptosis, and 6.2% of cells to necrosis. The treatment of doxorubicin, B. infantis milk, and the combination of them inhibited the tumor volumes by 55.50%, 40.69%, and 75.95%, respectively. B. infantis administration significantly enhanced the PHA-induced splenocyte proliferation (P < 0.05). It was shown that IFN-γ was effective in tumor growth and regression of metastasis. Consequently, the combination of B. infantis milk and doxorubicin showed the best anti-tumor effect.

Abstract
The importance of Ca2+ signaling, and particularly Ca2+ channels, in key events of cancer cell function such as proliferation, metastasis, autophagy and angiogenesis, has recently begun to be appreciated. Of particular note are two-pore channels (TPCs), a group of recently identified Ca2+-channels, located within the endolysosomal system. TPC2 has recently emerged as an intracellular ion channel of significant pathophysiological relevance, specifically in cancer, and interest in its role as an anti-cancer drug target has begun to be explored. Herein, an overview of the cancer-related functions of TPC2 and a discussion of its potential as a target for therapeutic intervention, including a summary of clinical trials examining the TPC2 inhibitors, naringenin, tetrandrine, and verapamil for the treatment of various cancers is provided.

Abstract
Eupatorin is a polymethoxy flavone extracted from Orthosiphon stamineus and was reported to exhibit cytotoxic effects on several cancer cell lines. However, its effect as an anti-breast cancer agent in vivo has yet to be determined. This study aims to elucidate the potential of eupatorin as an anti-breast cancer agent in vivo using 4T1 challenged BALB/c mice model. In this article, BALB/c mice (20-22 g) challenged with 4T1 cells were treated with 5 mg/kg or 20 mg/kg eupatorin, while the untreated and healthy mice were fed with olive oil (vehicle) via oral gavage. After 28 days of experiment, the mice were sacrificed and blood was collected for serum cytokine assay, while tumors were harvested to extract RNA and protein for gene expression assay and hematoxylin-eosin staining. Organs such as spleen and lung were harvested for immune suppression and clonogenic assay, respectively. Eupatorin (20 mg/kg) was effective in delaying the tumor development and reducing metastasis to the lung compared with the untreated mice. Eupatorin (20 mg/kg) also enhanced the immunity as the population of NK1.1+ and CD8+ in the splenocytes and the serum interferon-γ were increased. Concurrently, eupatorin treatment also has downregulated the expression of pro-inflammatory and metastatic related genes (IL-1β. MMP9, TNF-α, and NF-κB). Thus, this study demonstrated that eupatorin at the highest dosage of 20 mg/kg body weight was effective in delaying the 4T1-induced breast tumor growth in the animal model.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Locally known as 'pecah batu', 'bayam karang', 'keci beling' or 'batu jin', the Malaysian medicinal herb, Strobilanthes crispus (S. crispus), is traditionally used by the local communities as alternative or adjuvant remedy for cancer and other ailments and to boost the immune system. S. crispus has demonstrated multiple anticancer therapeutic potential in vitro and in vivo. A pharmacologically active fraction of S. crispus has been identified and termed as F3. Major constituents profiled in F3 include lutein and β-sitosterol. AIM OF THE STUDY In this study, the effects of F3, lutein and β-sitosterol on tumor development and metastasis were investigated in 4T1-induced mouse mammary carcinoma model. MATERIALS AND METHODS Tumor-bearing mice were fed with F3 (100 mg/kg/day), lutein (50 mg/kg/day) and β-sitosterol (50 mg/kg/day) for 30 days (n = 5 each group). Tumor physical growth parameters, animal body weight and development of secondary tumors were investigated. The safety profile of F3 was assessed using hematological and histomorphological changes on the major organs in normal control mice (NM). RESULTS Our findings revealed significant reduction of physical tumor growth parameters in all tumor-bearing mice treated with F3 (TM-F3), lutein (TM-L) or β-sitosterol (TM-β) as compared with the untreated group (TM). Statistically significant reduction in body weight was observed in TM compared to the NM or treated (TM-F3, TM-L and TM-β) groups. Histomorphological examination of tissue sections from the F3-treated group showed normal features of the vital organs (i.e., liver, kidneys, lungs and spleen) which were similar to those of NM. Administration of F3 to NM mice (NM-F3) did not cause significant changes in full blood count values. CONCLUSION F3 significantly reduced the total tumor burden and prevented secondary tumor development in metastatic breast cancer without significant toxicities in 4T1-induced mouse mammary carcinoma model. The current study provides further support for therapeutic development of F3 with further pharmacokinetics studies.

Abstract
Owing to their tunable properties, controllable degradation, and ability to protect labile drugs, hydrogels are increasingly investigated as local drug delivery systems. However, a lack of standardized methodologies used to characterize and evaluate drug release poses significant difficulties when comparing findings from different investigations, preventing an accurate assessment of systems. Here, we review the commonly used analytical techniques for drug detection and quantification from hydrogel delivery systems. The experimental conditions of drug release in saline solutions and their impact are discussed, along with the main mathematical and statistical approaches to characterize drug release profiles. We also review methods to determine drug diffusion coefficients and in vitro and in vivo models used to assess drug release and efficacy with the goal to provide guidelines and harmonized practices when investigating novel hydrogel drug delivery systems.

Abstract
This study aimed to investigate the potential role of co-treatment with doxorubicin (DOX) and verapamil (VRP) nanoparticles in experimentally induced hepatocellular carcinoma in mice and to investigate the possible mechanisms behind the potential favorable effect of the co-treatment. DOX and VRP were loaded into chitosan nanoparticles (CHNPs), and cytotoxicity of loaded and unloaded drugs against HepG2 cells was evaluated. Male albino mice were divided into eight groups (n = 15): (1) normal control, (2) diethylnitrosamine, (3) CHNPs, (4) free DOX, (5) CHNPs DOX, (6) free VRP, (7) CHNPs VRP, and (8) CHNPs DOX + CHNPs VRP. Either VRP or DOX loaded into CHNPs showed stronger growth inhibition of HepG2 cells than their free forms. DOX or VRP nanoparticles displayed pronounced anticancer activity in vivo through the decline of vascular endothelial growth factor and B cell lymphoma-2 contents in liver tissues, upregulation of antioxidant enzymes, and downregulation of multidrug resistance 1. Moreover, reduced cardiotoxicity was evident from decreased level of tumor necrosis factor-α and malondialdehyde in heart tissues coupled with decreased serum activity of creatine kinase-myocardial band and lactate dehydrogenase. Co-treatment with CHNPs DOX and CHNPs VRP showed superior results versus other treatments. Liver sections from the co-treatment group revealed the absence of necrosis, enhanced apoptosis, and nearly normal hepatic lobule architecture. Co-treatment with CHNPs DOX and CHNPs VRP revealed enhanced anticancer activity and decreased cardiotoxicity versus the corresponding free forms.

Abstract
OBJECTIVE The MDR of metastatic breast cancer cells is accompanied by the overexpression of P-gp transporter. This study has been focused to determine whether silencing the expression of P-gp by aptamer-labeled siRNA nanoparticles could enhance the delivery of doxorubicin into breast cancer cells in culture. METHODOLOGY The nanoparticle F-31 was prepared using DOTAP, cholesterol, and PLGA, and then incorporating Mal-PEG to facilitate aptamer-binding. The nanoparticles were surface-functionalized with aptamer A6, which targets Her-2 receptors overexpressed on the surface of breast cancer cells. RESULTS This study has shown that the uptake of Dox by Dox-resistant 4T1-R is significantly less than Dox-sensitive 4T1-S which is partly attributed to the higher expression of drug-efflux pump P-gp on the surface of the resistant cells. The targeted knockdown of P-gp has been enhanced when the particles carrying P-gp siRNA was labeled with aptamer. Concurrently, the uptake of Dox into the Dox-resistant 4T1-R breast cancer cells has increased significantly when the P-gp was silenced by P-gp siRNA-encapsulated aptamer-labeled nanoparticles. CONCLUSIONS This preliminary study concludes that downregulating P-gp expression by targeted delivery of P-gp siRNA using aptamer-labeled lipid-based hybrid nanoparticles could effectively increase the intracellular trafficking of doxorubicin in Dox-resistant mouse breast cancer cells.

Abstract
Aim: Breast cancer is the most common cancer among Arab women and also around the world. Chronic cardiotoxicity and multidrug resistance are potential limiting factors of doxorubicin (DOX), a known anthracycline antibiotic. Materials & methods: DOX cytotoxicity was evaluated by the sulforhodamine method. DOX cellular uptake, detection of P-glycoprotein activity and the photomicrograph of MCF-7 cells were also determined. Results: Diltiazem (DIL) treatment improved DOX cytotoxic activity and increased the cellular uptake of DOX significantly and aggregation of rhodamine 123, reflecting inhibition of P-glycoprotein pump. Cytopathological investigation of MCF-7 cells revealed marked cytotoxic activity of DOX in the presence of DIL. Conclusion: DIL treatment enhanced DOX cytotoxic effect and reduced multidrug resistance, which increased the drug accumulation intracellularly.

Abstract
The incidence of gastric cancer is extremely high in China, prompting the development of effective therapeutic strategies. Sodium selenite (SS) affects the proliferation and redifferentiation of gastric cancer cells and the Adriamycin prodrug Ac-Phe-Lys-PABC-ADM (PADM) reduces toxicity in gastric cancer treatment. However, the mechanisms involved therein remain unclear. In this study, nude mice were transplanted with SGC-7901 gastric cancer cells to construct a tumor xenograft model. After administration of SS and PADM, tumor weight and size were reduced. In addition, the levels of alanine aminotransferase, aspartate transaminase, creatinine, and lactate dehydrogenase were decreased, indicating improved hepatic and renal function and inhibited cancer cell metabolism. Furthermore, combined treatment of SS and PADM downregulated the expression of cell cycle-related proteins (cyclin-dependent kinase 4, Ki67, cyclin E, and cyclin D1), elevated that of proapoptosis proteins (Bax, cleaved caspase-3, cleaved caspase-9, and P53), and upregulated that of mitochondrial apoptosis-associated proteins (apoptotic protease activating factor 1 and second mitochondria-derived activator of caspases). In conclusion, combined treatment of SS and PADM effectively promoted apoptosis in gastric cancer xenografts via the mitochondrial apoptosis pathway.

Abstract
Background There are currently a number of barriers hindering the successful treatment of breast cancer, including the metastatic spread of cancer cells. In looking for new anticancer agents, we reported two novel hydrazide derivatives with anti-cancer activity in human breast cancer cells. The current study aims to explore the therapeutic potential of the most effective one, N'-((5-nitrothiophen-2-yl)methylene)-2-(phenylthio)benzohydrazide (compound B), on metastatic breast cancer, which is resistant to available chemotherapeutics. Methods 4T1 mammary carcinoma cells were inoculated into the fat pad mammary of 5–7-week-old female BALB/c mice and then the effective compound was intraperitoneally administered for 4 weeks. Proliferation index and angiogenesis in tumor and lung tissues were examined with immunohistochemistry. In vitro assessments were also carried out to evaluate the effect of the compound on invasion of MDA-MB-231 cells. Results Our results demonstrated that this effective derivative significantly inhibited invasion of MDA-MB-231 cells in vitro as shown by Matrigel assay and quantitative real-time method for MMP-9 expression after 48 h of treatment. Daily administration of the compound suppressed the growth of primary tumor and its metastasis to lung, which was confirmed by H&E experiment at a dose of 1 mg/kg in a well-known metastatic model of 4T1 breast cancer in syngeneic BALB/c mice. These outcomes were supported by the immunohistochemical examinations of the tumor and lung tissues of mice. Tumors and lungs in mice treated with the effective compound showed a reduced proliferation index and a smaller microvessel density compared to the control. Conclusion This study highlights an anti-metastatic role for a novel hydrazide derivative in both in vitro and in vivo models of breast cancer.

Abstract
The incidence of aspergillosis continues to rise sharply, while the progress made in expanding the antifungal drug arsenal remains extremely slow, indicating an urgent need for new strategies. Previous studies have shown that the calcium signaling pathway, which is evolutionarily conserved in mammals and fungi, is involved in regulating the tolerance of azoles in fungi. In this study, we performed a preliminary screening among various combinations of different clinical calcium channel blockers and different antifungal drugs. We found that the combination of itraconazole and verapamil showed the best synergistic effect against Aspergillus fumigatus. Thereafter, using the checkboard assays we observed synergistic effects of the combination treatment against most of the A. fumigatus strains tested, including itraconazole-sensitive and itraconazole-resistant strains, with a fractional inhibitory concentration index (FICI) < 0.5. Furthermore, we showed that verapamil strongly decreased the cytosolic calcium transients following itraconazole stimulation by an aequorin-mediated method. Moreover, verapamil influenced the efflux of rhodamine 6G, an azole mimic substance. An ergosterol assay revealed that verapamil alone had no effect on ergosterol biosynthesis, but the combination of itraconazole and verapamil treatment decreased the ergosterol level. Further murine assays were performed using a luciferase-probed bioluminescence imaging method. Drug combination therapy reduced lung burden and improved survival rate. In conclusion, verapamil is a promising candidate to enhance the antifungal activity of itraconazole against A. fumigatus. In addition, our study suggests the effectiveness of an emerging approach based on bioluminescence imaging in monitoring the efficacy of drug combination therapy for invasive aspergillosis.

Abstract
BACKGROUND Allium species are magnificently nutritious and are commonly used as a part of the diet in Iran. They have health enhancing benefits including anticancer properties due to the presence of numerous bioactive compounds. Herein, we investigated in vitro and in vivo anticancer properties of Allium bakhtiaricum extracts. METHODS Anti-growth activity of different fractions was explored in vitro on different cancerous cells using MTT assay, Annexin V/PI and SA-β-gal staining, Western blotting, flowcytometric and immunofluorescence microscopic evaluations. In vivo antitumor activity was investigated in BALB/c mice bearing 4 T1 mammary carcinoma cells. RESULTS We demonstrated that chloroformic and ethyl acetate fractions exert cytotoxic activity toward MDA-MB-231 cells, the most sensitive cell line, after 72 h of treatment with IC50 values of 0.005 and 0.006 mg/ml, respectively. Incubation of MDA-MB-231 cells with ¼ and ½ IC50-72h concentrations of each fraction resulted in a significant G2/M cell cycle arrest. ¼ IC50-72h concentration of the chloroform fraction led to the disruption of polymerization in mitotic microtubules. Exposure of human breast cancer cells to different concentrations of the extracts at different incubation times did not induce apoptosis, autophagy or senescence. Our in vivo study revealed that administration of the chloroform extract at a dose of 1 mg/kg/day strongly suppressed mammary tumor progression and decreased the number of proliferative cells in the lung tissues indicating its anti-metastatic effect. CONCLUSION Our findings imply that the chloroform fraction of Allium bakhtiaricum possesses the suppressive action on breast cancer through mitotic cell cycle arrest suggesting a mechanism associated with disturbing microtubule polymerization.

Abstract
The first-line chemotherapy drug adriamycin (ADM) is widely used for the treatment of breast cancer, but the acquired drug resistance and the normal tissue toxicity remain clinical challenges. Alteronol has been reported to exert wide-ranging anti-tumor activity. In this study, we firstly examined the synergistic anti-tumor effects and the underlying mechanisms of alteronol combined with ADM in breast cancer. We have found that the combination of alteronol and ADM significantly suppressed the expression levels of the cell cycle-related proteins (CDC2 and Cyclin B1) and induced cell cycle arrest at the G2/M phase, leading to cell proliferation inhibition in breast cancer 4T1 cells. Moreover, co-treatment of alteronol and ADM (i) remarkably activated p38 and JNK kinases, (ii) elevated ROS levels, (iii) triggered mitochondrial dysfunction, (iv) released cytochrome c into the cytoplasm, (v) upregulated apoptosis-related proteins, e.g., cleaved PARP, Bax, and cleaved caspase-3/9, and (vi) downregulated the expression of Bcl-2, followed by apoptosis. Furthermore, our in vivo studies showed that the low-dose combination of alteronol (2 mg/kg) and ADM (1 mg/kg) significantly inhibited tumor growth in tumor bearing mice, and the anti-tumor effect of the combination was the same as that of high-dose ADM (8 mg/kg). In addition, the low-dose combination group showed lower toxicities to major organs than the high-dose ADM group. Taken together, these data demonstrate that the low-dose combination of alteronol and ADM could notably improve the anti-tumor activity and have lower toxicities to major organs than those in high-dose ADM group.

Abstract
Hydrogel is an ideal scaffold in the fields of regenerative medicine and tumor therapy because of its biomimetic ability to modulate tissue microenvironment. Herein, we fabricated a new kind of self-healing hydrogel based on graphene nanoparticle and expanded its application in postoperative recurrence of breast cancer. First, a facile method was used to prepare self-healing hydrogel via Schiff-base linkage, which composed of chondroitin sulfate multialdehyde (CSMA), branched polyethylenimine (BPEI) and BPEI conjugated graphene (BPEI-GO). BPEI-GO was doped in the network and participated in Schiff-base reaction and stabilized the structure, as well as provided sustained drug delivery, and near-infrared laser (NIR)-triggered photothermal effect. The hydrogels exhibited excellent self-healing (∼100%) and improved mechanical properties (7,000 Pa). Further, in vitro breast cancer cell inhibition study showed enhanced cell killing efficiency with synergistic chemo-photothermal therapy. In the breast cancer postoperative recurrence prevention mice model, we found that combination of Doxorubicin (DOX) and photothermal therapy in CSMA/BPEI/BPEI-GO hydrogels group reduced tumor recurrence to 33.3%, compared with 66.7% for DOX-loaded hydrogels without NIR irradiation, 66.7% for local administration of free DOX, 100% for hydrogels with NIR irradiation, blank hydrogels, and blank control. This study suggests the great potential of CSMA/BPEI/BPEI-GO hydrogels for postoperative recurrence prevention of breast cancer.

Abstract
BACKGROUND AND OBJECTIVE Doxorubicin (DOX), despite having antitumor properties, also exhibits cardiotoxicity. Resveratrol has antitumor property for breast cancer cells. 99mTc-MIBI has higher absorption rate in human breast cancer cell line MCF-7. In the present study, the authors intend to investigate the effect of DOX and resveratrol on the absorption of 99mTc-MIBI in breast cancer cell xenografts in mice. MATERIALS AND METHODS Sixteen xenograft models in nude mice were divided into four groups. Group I (S, control) received 2% DMSO in 0.9% saline, group II (D) 2.5 mg/kg DOX, group III (D + R) 20 mg/kg/d resveratrol with 2.5 mg/kg DOX (total dose of 15 mg/kg in six injections), and group IV (R) 20 mg/kg/d resveratrol for 2 weeks. Single-photon emission computed tomography (SPECT) images were taken for the determination of 99mTc-MIBI absorption. Mice were sacrificed, and the percentage of injected dose per gram (%ID/g) of the heart, liver, tumor, and muscle was measured using a gamma counter. Hematoxylin-eosin staining and Masson's trichrome staining were used for investigation of histopathological changes. RESULTS The %ID/g of tumor was lowest in group D + R. The severity of tumor necrosis or apoptosis was highest in group D + R, but there is no significant difference in pathological injuries and %ID/g of tumor between the group D + R and group D. In addition to the results of the %ID/g, the severity of pathological injuries to the liver and heart cells in group D + R was higher compared with group D. There is a significant difference in the %ID/g of the liver between the group D + R and group D. SPECT images showed that the lowest amount of %ID/g was observed in the tumor of group D + R. CONCLUSIONS According to the results of pathology, biodistribution study, and imaging, the combination of DOX and resveratrol has shown higher antitumor effect; hence, 99mTc-MIBI can be used to evaluate their antitumor effect.

Verapamil and riluzole cocktail liposomes overcome pharmacoresistance by inhibiting P-glycoprotein in brain endothelial and astrocyte cells: A potent approach to treat amyotrophic lateral sclerosis. Eur J Pharm Sci 2018; 120:30-39. [PMID: 29704642 DOI: 10.1016/j.ejps.2018.04.026] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2017] [Revised: 04/03/2018] [Accepted: 04/18/2018] [Indexed: 12/13/2022]
Abstract
Riluzole is currently one of two approved medications for the treatment of amyotrophic lateral sclerosis (ALS). However, brain disposition of riluzole, as a substrate of P-glycoprotein (P-gp), is limited by the efflux transporters at the blood-brain barrier (BBB). We propose to develop a liposomal co-delivery system that could effectively transport riluzole to brain cells by reducing efflux pumps with a P-gp inhibitor, verapamil. Riluzole and verapamil cocktail liposomes were prepared by lipid film hydration. The average particle size of cocktail liposomes was 194.3 ± 6.0 nm and their polydispersity index (PDI) was 0.272 ± 0.017. The encapsulation efficiencies of verapamil and riluzole in the cocktail liposomes were 86.0 ± 1.4% and 85.6 ± 1.1%, respectively. The drug release from cocktail liposomes after 8 h in PBS at 37 °C was 78.4 ± 6.2% of riluzole and 76.7 ± 3.8% of verapamil. The average particle size of liposomes did not show significant changes at 4 °C after three months. Verapamil cocktail liposomes inhibited P-gp levels measured by western blotting in dose and time-dependent manners in brain endothelial bEND.3 cells. Increased drug efflux transporters were detected in bEND.3 and astrocytes C8D1A cells, promoted by tumor necrosis factor (TNF-α) or hydrogen peroxide (H2O2). Restored accumulations of riluzole and fluorescent dye rhodamine 123 were observed in bEND.3 cells after treatments with cocktail liposomes. It indicated that inhibitory potential of co-delivery liposome system towards P-gp could mediate the transport of both P-gp substrates. Verapamil and riluzole co-loaded liposomes may be used to overcome pharmacoresistance of riluzole for improving ALS therapy.

Abstract
In the study, we probed into the effect of Resveratrol (RES) on Doxorubicin (DOX)-resistant breast neoplasm cell line MCF-7/DOX as well as the mechanism of RES underlying the DOX-resistant breast cancer. CCK-8 assay was utilized to assess the survival rates and sensitivity of breast neoplasm cell lines MCF-7 or MDA-MB-231 to DOX and RES. DOX-resistant MCF-7 cell line was successfully cultivated with DOX dose increasing and was named MCF-7/DOX. Afterwards, wound healing and Transwell assays were performed to measure the migration and invasion capabilities of MCF-7/DOX cells, while cell propagation and apoptosis were determined by colony formation assay and flow cytometry analysis. Both western blotting and immunohistochemistry were conducted to examine the expression of proteins involved in PI3K/Akt signaling pathway. Nude mice xenograft model was constructed to further verify the effects of DOX and RES on breast neoplasm in vivo. RES restored DOX sensitivity in MCF-7/DOX cells, inhibiting biological functions of MCF-7/DOX cells and promoting cell apoptosis in vitro and impeding tumor growth in vivo. It was revealed by the mechanistic studies that MCF-7/DOX cells could regain the drug sensibility with RES treatment through inactivating the PI3K/Akt signal transduction pathway. RES could reverse DOX resistance in breast neoplasm cells and inhibited DOX-resistant breast cancer cell propagation and metastasis and facilitated cell apoptosis by modulating PI3K/Akt signaling pathway. © 2018 IUBMB Life, 70(6):491-500, 2018.

Abstract
BACKGROUND Multidrug resistance (MDR) and drug transporter P-glycoprotein (P-gp) represent major obstacles in cancer chemotherapy. We investigated 19 synthetic curcumin derivatives in drug-sensitive acute lymphoblastic CCRF-CEM leukemia cells and their multidrug-resistant P-gp-overexpressing subline, CEM/ADR5000. MATERIAL AND METHODS Cytotoxicity was tested by resazurin assays. Doxorubicin uptake was assessed by flow cytometry. Binding modes of compounds to P-gp were analyzed by molecular docking. Chemical features responsible for bioactivity were studied by quantitative structure activity relationship (QSAR) analyses. A 7-descriptor QSAR model was correlated with doxorubicin uptake values, IC50 values and binding energies. RESULTS The compounds displayed IC50 values between 0.7±0.03 and 20.2±0.25μM. CEM/ADR5000 cells exhibited cross-resistance to 10 compounds, collateral sensitivity to three compounds and regular sensitivity to the remaining six curcumins. Molecular docking studies at the intra-channel transmembrane domain of human P-gp resulted in lowest binding energies ranging from -9.00±0.10 to -6.20±0.02kcal/mol and pKi values from 0.24±0.04 to 29.17±0.88μM. At the ATP-binding site of P-gp, lowest binding energies ranged from -9.78±0.17 to -6.79±0.01kcal/mol and pKi values from 0.07±0.02 to 0.03±0.03μM. CEM/ADR5000 cells accumulated approximately 4-fold less doxorubicin than CCRF-CEM cells. The control P-gp inhibitor, verapamil, partially increased doxorubicin uptake in CEM/ADR5000 cells. Six curcumins increased doxorubicin uptake in resistant cells or even exceeded uptake levels compared to sensitive one. QSAR yielded good activity prediction (R=0.797 and R=0.794 for training and test sets). CONCLUSION Selected derivatives may serve to guide future design of novel P-gp inhibitors and collateral sensitive drugs to combat MDR.

Abstract
Breast cancer is the second largest disease affecting women worldwide. It remains the most frequently reported and leading cause of death among women in both developed and developing countries. Tamoxifen and raloxifene are commonly used selective estrogen receptor modulators for treatment of breast cancer in women with high risk, although resistance occurs by tamoxifen after 5 years of therapy and both drugs cause uterine cancer and thromboembolic events. Aromatase inhibitors (AIs) are one of the optional modes used for breast cancer treatment. The combination of AIs along with tamoxifen can also be beneficial. Various therapeutic agents from different sources are being studied, which further need to be improved for potential outcome. For this, clinical trials based on large number of patients with optimal dose and lesser side effects have to be more in practice. Despite the clinical trials going on, there is need of better molecular models, which can identify high risk population, new agents with better benefit having less side effects, and improved biomarkers for treating breast cancer.

Abstract
Despite the major progresses in biomedical research and the development of novel therapeutics and treatment strategies, cancer is still among the dominant causes of death worldwide. One of the crucial challenges in the clinical management of cancer is primary (intrinsic) and secondary (acquired) resistance to both conventional and targeted chemotherapeutics. Multiple mechanisms have been identifiedthat underlie intrinsic and acquired chemoresistance: these include impaired drug uptake, increased drug efflux, deletion of receptors, altered drug metabolism, quantitative and qualitative alterations in drug targets, increased DNA damage repair and various mechanisms of anti-apoptosis. The fast efflux of anticancer drugs mediated by multidrug efflux pumps and the partial or complete reversibility of chemoresistance combined with the absence of genetic mutations suggests a multifactorial process. However, a growing body of recent evidence suggests that chemoresistance is often triggered by the highly acidic microenvironment of tumors. The vast majority of drugs, including conventional chemotherapeutics and more recent biological agents, are weak bases that are quickly protonated and neutralized in acidic environments, such as the extracellular microenvironment and the acidic organelles of tumor cells. It is therefore essential to develop new strategies to overcome the entrapment and neutralization of weak base drugs. One such strategy is the use of proton pump inhibitors which can enhance tumor chemosensitivity by increasing the pH of the tumor microenvironment. Recent clinical trials in animals with spontaneous tumors have indicated that patient alkalization is capable of reversing acquired chemoresistance in a large percentage of tumors that are refractory to chemotherapy. Of particular interest was the benefit of alkalization for patients undergoing metronomic regimens which are becoming more widely used in veterinary medicine. Overall, these results provide substantial new evidence that altering the acidic tumor microenvironment is an effective, well tolerated and low cost strategy for the overcoming of anticancer drug resistance.

Abstract
Hyaluronic acid (HA) is a mucopolysaccharide acid composed of repeating disaccharide units of D-glucuronic acid and N-acetyl-D-glucosamine. Based on numerous characteristics such as viscoelastic properties, water-binding ability, biocompatibility and non-immunogenicity, HA has been approved by FDA for biological and medical applications. In addition, multifarious receptors of HA like CD44, RHAMM and TSG6 are over-expressed on the surface of malignant cells, which play important roles in targeting ability. Bioconjugates linking drugs to HA could improve solubility, prolong half-life, provide active targeting capability and then increase the bioavailability of these coupled drugs by pro-drug strategy. Therefore, a large number of HA-drug bioconjugates have been studied. The purpose of this review was to summarize these HA-drug bioconjugates and further discuss synthetic methods and the relevant application in pharmaceuticals.
