Abstract
BACKGROUNDTargeted arterial infusion of verapamil combined with chemotherapy (TVCC) is an effective clinical interventional therapy for esophageal squamous cell carcinoma (ESCC), but multidrug resistance (MDR) remains the major cause of relapse or poor prognosis, and the underlying molecular mechanisms of MDR, temporal intratumoral heterogeneity, and clonal evolutionary processes of resistance have not been determined.METHODSTo elucidate the roles of genetic and epigenetic alterations in the evolution of acquired resistance during therapies, we performed whole-exome sequencing on 16 serial specimens from 7 patients with ESCC at every cycle of therapeutic intervention from 3 groups, complete response, partial response, and progressive disease, and we performed whole-genome bisulfite sequencing for 3 of these 7 patients, 1 patient from each group.RESULTSPatients with progressive disease exhibited a substantially higher genomic and epigenomic temporal heterogeneity. Subclonal expansions driven by the beneficial new mutations were observed during combined therapies, which explained the emergence of MDR. Notably, SLC7A8 was identified as a potentially novel MDR gene, and functional assays demonstrated that mutant SLC7A8 promoted the resistance phenotypes of ESCC cell lines. Promoter methylation dynamics during treatments revealed 8 drug resistance protein-coding genes characterized by hypomethylation in promoter regions. Intriguingly, promoter hypomethylation of SLC8A3 and mutant SLC7A8 were enriched in an identical pathway, protein digestion and absorption, indicating a potentially novel MDR mechanism during treatments.CONCLUSIONOur integrated multiomics investigations revealed the dynamics of temporal genetic and epigenetic inter- and intratumoral heterogeneity, clonal evolutionary processes, and epigenomic changes, providing potential MDR therapeutic targets in treatment-resistant patients with ESCC during combined therapies.FUNDINGNational Natural Science Foundation of China, Science Foundation of Peking University Cancer Hospital, CAMS Innovation Fund for Medical Sciences, Major Program of Shenzhen Bay Laboratory, Guangdong Basic and Applied Basic Research Foundation, and the third round of public welfare development and reform pilot projects of Beijing Municipal Medical Research Institutes.

Abstract
Cancer is a complex group of diseases that constitute the second largest cause of mortality worldwide. The development of new drugs for treating this disease is a long and costly process, from the discovery of the molecule through testing in phase III clinical trials, a process during which most candidate molecules fail. The use of drugs currently employed for the management of other diseases (drug repurposing) represents an alternative for developing new medical treatments. Repurposing existing drugs is, in principle, cheaper and faster than developing new drugs. Antihypertensive drugs, primarily belonging to the pharmacological categories of angiotensin-converting enzyme inhibitors, angiotensin II receptors, direct aldosterone antagonists, β-blockers and calcium channel blockers, are commonly prescribed and have well-known safety profiles. Additionally, some of these drugs have exhibited pharmacological properties useful for the treatment of cancer, rendering them candidates for drug repurposing. In this review, we examine the preclinical and clinical evidence for utilizing antihypertensive agents in the treatment of cancer.

Abstract
BACKGROUND AND PURPOSE Selective ophthalmic artery infusion chemotherapy has improved ocular outcomes in children with retinoblastoma. Our aim was to correlate quantitative tumor reduction and dichotomous therapeutic response with technical and adjunctive factors during selective ophthalmic artery infusion chemotherapy for retinoblastoma. An understanding of such factors may improve therapeutic efficacy. MATERIALS AND METHODS All patients with retinoblastoma treated by selective ophthalmic artery infusion chemotherapy at a single center during a 9-year period were reviewed. Only first-cycle treatments for previously untreated eyes were studied. Adjunctive factors (intra-arterial verapamil, intranasal oxymetazoline external carotid balloon occlusion) and technical factors (chemotherapy infusion time, fluoroscopy time) were documented by medical record review. Quantitative tumor reduction was determined by blinded comparison of retinal imaging acquired during examination under anesthesia before and 3-4 weeks after treatment. The dichotomous therapeutic response was classified according to quantitative tumor reduction as satisfactory (≥ 50%) or poor (<50%). RESULTS Twenty-one eyes met the inclusion criteria. Patients ranged from 2 to 59 months of age. Adjuncts included intra-arterial verapamil in 15, intranasal oxymetazoline in 14, and external carotid balloon occlusion in 14. Quantitative tumor reduction ranged from 15% to 95%. Six showed poor dichotomous therapeutic response. A satisfactory dichotomous therapeutic response was correlated with intra-arterial verapamil (P = .03) in the aggregate cohort and in a subgroup undergoing treatment with single-agent melphalan at a dose of <5 mg (P = .02). In the latter, higher average quantitative tumor reduction correlated with intra-arterial verapamil (P < .01). CONCLUSIONS Intra-arterial verapamil during selective ophthalmic artery infusion chemotherapy is correlated with an improved therapeutic response, particularly when treating with lower doses of single-agent melphalan.

Cancer Manag Res 2020; 12:1913-1927. [PMID: 32214849 PMCID: PMC7078713 DOI: 10.2147/cmar.s228718] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2019] [Accepted: 02/13/2020] [Indexed: 12/16/2022] Open
Abstract
Purpose Hypertension and cancer are frequently found comorbidity occurring in same individual. This study was intended to evaluate the anticancer effects of commonly used antihypertensive medications and chemotherapy on chemoresistant lung cancer cells. Methods Calcium channel blockers (CCBs), including Verapamil, Diltiazem, and Nifedipine, either alone or combined with docetaxel (DOC) or vincristine (VCR) were used to treat A549 lung adenocarcinoma chemoresistant sublines. Cell viability was determined by MTT assay, and colony formation assay was used to demonstrate the long-term effect of CCBs on proliferation of the sublines. Apoptosis was evaluated by Annexin V assay and autophagy intensity was quantitated from acidic vesicular organelle formation. Pan-caspase inhibitor, shATG5 interference and chloroquine were applied to study the roles of Verapamil on apoptosis and autophagy, with related proteins verified by Western blot analysis. Results Results show that 10 μM of Verapamil and Diltiazem, but not Nifedipine, differentially induce autophagy in DOC-resistant or VCR-resistant A549 cells, respectively. When CCBs are combined with DOC or VCR to treat the sublines, 10 μM of Verapamil induces autophagy more significantly than Diltiazem and Nifedipine, respectively, in DOC-resistant (54.91±0.76, 18.03±0.69, 7.05±0.30) or VCR-resistant A549 (32.41±1.04, 21.51±0.63, 7.14±0.24) cells. Inhibition of apoptosis by pan-caspase inhibitor partly reduced cell death indicates association of caspase-dependent cell death but with persistence of autophagy. Inhibition of autophagy by interfering ATG5 expression reduced c-PARP level and apoptotic cells suggest a pro-death role of autophagy. Chloroquine treatment enhanced autophagosome accumulation and cell death but with reduced c-PARP level suggests that mechanism of caspase-independent cell death also contributes to Verapamil/chemotherapy-induced anticancer effects. Conclusion Verapamil combined with DOC or VCR induces chemoresistant lung cancer cells to death through autophagy burst and apoptosis more strongly than Diltiazem and Nifedipine. Administering Verapamil or Diltiazem individually with chemotherapy, but not Nifedipine, can be considered in lung cancer patients with hypertension.

Abstract
Multidrug resistance (MDR) is one of the major obstacles to clinical cancer chemotherapy. Herein, we designed new pH-sensitive pluronic micelles with the synergistic effects of oxidative therapy and MDR reversal. Pluronic (P123) was modified with α-tocopheryl succinate (α-TOS) via an acid-labile ortho ester (OE) linkage to give a pH-sensitive copolymer (POT). Self-assembled POT micelles exhibited desirable size (~80 nm), excellent anti-dilution ability, high drug loading (~85%), acid-triggered degradation and drug release behaviours. In vitro cell experiments verified that POT micelles could significantly reverse MDR through suppressing the function of drug effluxs mediated by P123 and induce more reactive oxygen species (ROS) generation mediated by α-TOS, resulting in enhanced cytotoxicity and apoptosis in MDR cells. In vivo studies further revealed that DOX-loaded POT micelles (POT-DOX) possessed the highest drug accumulation (3.03% ID/g at 24 h) and the strongest tumour growth inhibition (TGI 83.48%). Pathological analysis also indicated that POT-DOX could induce more apoptosis or necrosis at the site of tumour without distinct damage to normal tissues. Overall, these smart POT micelles have great potential as promising nano-carriers for MDR reversal and cancer treatment.

Abstract
BACKGROUND The aim of this study was to investigate the role of ubiquitin carboxyl-terminal hydrolase L1 (UCHL1) in the reversal effect of verapamil (VER) on chemo-resistance to Adriamycin (ADM) in treatment of hepatocellular carcinoma (HCC). MATERIAL AND METHODS HCC cell lines SMMC-7721 and BEL-7402 were used as model cell lines. High-throughput transcriptome sequencing based on Illumina technology was used to screen whether UCHL1 mediated the reversal effect of VER on chemo-resistance. Quantitative real-time PCR (qRT-PCR) was performed to determine the expression level of UCHL1 mRNA in HCC cells, and western blot analysis was performed to examine the protein expression of UCHL1 protein in HCC cells. Immunohistochemistry assay was performed to determine the protein expression of UCHL1 in tissue samples from patients presenting with either positive or negative responses to the reversal therapeutic regimen of VER. Moreover, cell models with UCHL1 knockdown and overexpression were established to examine the reversal effect of VER on chemo-resistance to ADM in HCC cells. Cell apoptosis was determined by flow cytometry following Annexin V-PI staining. RESULTS The expression levels of UCHL1 genes correlated with the level of apoptosis induced by ADM+VER. Overexpression of UCHL1 genes promoted apoptosis in cells treated with VER+ADM. UCHL1 knockdown using siRNA weakened the effect of ADM+VER, indicating that ADM+VER promotes HCC cell apoptosis and that UCHL1 genes participate in VER-mediated promotion in tumor cell apoptosis. CONCLUSIONS Upregulation of UCHL1 enhanced the reversal effect of VER on chemo-resistance to ADM and promoted cell apoptosis. The underlying mechanism of the function of UCHL1 and the signaling pathway involved in its effect are to be investigated in our future research.

Abstract
Hepatocellular carcinoma (HCC) is one of the most lethal cancers worldwide. Surgical resection and liver transplantation are still the best options for treatment. Nevertheless, as the number of patients who may benefit from these therapies is limited, alternative therapies have been developed, including chemotherapy. However, partly due to the expression of multidrug resistance (MDR) proteins, it has been found that HCC is a highly chemoresistant tumor. The major family of MDR proteins is the ATP-binding cassette (ABC) transporter superfamily, which includes P-glycoprotein (Pgp) and MDR-associated protein 1 (MRP1). Positron emission tomography using the radiolabeled analog of glucose, 2-deoxy-2-((18)F)fluoro-D-glucose ([(18)F]FDG), has been used in diagnostic imaging of various types of tumors. Clinical studies are inconsistent but experimental studies have shown that [(18)F]FDG uptake is associated with tumor grade and is inversely proportional to Pgp expression in HCC. These studies unveil that [(18)F]FDG can be a substrate of Pgp, although that relationship remains unclear. This review sums up the relationship between MDR expression in HCC, and [(18)F]FDG uptake by tumor cells, showing that this radiopharmaceutical may provide a useful tool for the study of chemoresistance in HCC, and that the use of this marker may contribute to the therapeutic choice on this highly aggressive tumor.

Abstract
Despite continuous improvements in therapeutic protocols, cancer-related mortality is still one of the main problems facing public health. The main cause of treatment failure is multi-drug resistance (MDR: simultaneous insensitivity to different anti-cancer agents), the underlying molecular and biological mechanisms of which include the activity of ATP binding cassette (ABC) proteins and drug compartmentalisation in cell organelles. We investigated the expression of the main ABC proteins and the role of cytoplasmic vacuoles in the MDR of six hepatocellular carcinoma (HCC) cell lines, and confirmed the accumulation of the yellow anti-cancer drug sunitinib in giant (four lines) and small cytoplasmic vacuoles of lysosomal origin (two lines). ABC expression analyses showed that the main ABC protein harboured by all of the cell lines was PGP, whose expression was not limited to the cell membrane but was also found on lysosomes. MTT assays showed that the cell lines with giant lysosomes were more resistant to sorafenib treatment than those with small lysosomes (p<0.01), and that verapamil incubation can revert this resistance, especially if it is administered after drug pre-incubation. The findings of this study demonstrate the involvement of PGP-positive lysosomes in drug sequestration and MDR in HCC cell lines. The possibility of modulating this mechanism using PGP inhibitors could lead to the development of new targeted strategies to enhance HCC treatment.

Abstract
The present study evaluated the efficacy of chemotherapy combined with targeted arterial infusion of verapamil in patients with advanced gastric cancer. Forty patients were enrolled. Targeted arterial infusion of verapamil was done once a month, 3-5 times per patient, along with chemotherapy. After 2 bouts of combined treatment, the efficacy was evaluated. Primary gastric tumor was confirmed in 38/40 patients, and unconfirmed in 2/40 patients due to adhesion of tumors to surrounding tissue. Combined treatment was administered in 38 patients with defined tumors. Complete response to the treatment was in 5/38 (13.1 %) patients, partial response in 27/38 (71.1 %) patients, stable disease in 4/38 (10.5 %) patients, and progressive disease in 2/38 (5.26 %) patients. The effective rate (i.e., complete + partial response) comprised 84.2 %. There were 31 patients with liver metastases; 10/31 (32.3 %) patients showed complete response, 16/31 (51.6 %) patients showed partial response, 3/31 (9.7 %) patients had stable disease, and 2/31 (6.5 %) patients had progressive disease. The effective rate in these patients was 83.8 %. Thirty-seven patients were followed up, and 27/37 (73.0 %) patients were alive for 6 months or longer, 19/37 (51.3 %) for 12 months, 8 (35.1 %) for 18 months, and 8/37 (21.6 %) for 24 months. In conclusion, in patients with advanced gastric cancer, chemotherapy is more effective when combined with targeted arterial infusion of verapamil, leading to extended patients' survival and improved quality of life.

Abstract
PURPOSE To develop a reproducible technique for selective ophthalmic artery infusion chemotherapy (SOAIC) that is technically efficacious in children with unfavorable patterns of ophthalmic artery (OA) flow. MATERIALS AND METHODS Initially, all SOAIC was performed with intention to treat using a standard selective OA (microcatheter) infusion technique (sSOAIC). Temporary balloon occlusion (TBO) of the external carotid artery (ECA), a balloon-assisted SOAIC (bSOAIC) technique, was performed only if OA angiography did not show robust and sustained anterograde OA flow. In our more recent experience, all SOAIC was performed with intention to treat by bSOAIC. Verapamil infusion into the OA and internal carotid artery was performed in selected cases. Technical success was defined as delivery of chemotherapeutic agent(s) into the OA with robust and sustained anterograde perfusion. sSOAIC was considered to have failed if converted to bSOAIC. RESULTS 19 eyes were treated in 17 patients (age 5 months to 16 years) between December 2008 and May 2013. Eighty-three procedures were undertaken and the OA was successfully catheterized in all. Technical success was achieved in 35/41 (85%) sSOAIC cases and 42/42 (100%) bSOAIC cases. TBO of the ECA augmented anterograde OA flow and converted all cases of retrograde OA flow to anterograde. Verapamil further augmented anterograde ocular perfusion during SOAIC. There were no access site complications, strokes, or deaths. CONCLUSIONS TBO of the ECA is a safe, effective, and reproducible method for optimizing ocular hemodynamics during SOAIC regardless of baseline OA flow pattern. Verapamil infusion may further favorably modify OA flow. TRIAL REGISTRATION NUMBER NCT01466855.

Cancer Chemother Pharmacol 2014; 74:473-8. [PMID: 25027208 DOI: 10.1007/s00280-014-2532-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2014] [Accepted: 07/08/2014] [Indexed: 11/28/2022]
Abstract
PURPOSE To establish a simple method for estimating residual peritoneal ascites in order to determine the optimum verapamil (VRP) initial concentration in the intraperitoneal perfusion chemotherapy. METHODS (1) Pelvic size of adults was assessed by measuring distance from the superior margin of pubic symphysis to the connecting line of two anterior superior spine (SL) and to the midpoint of the line (SM) in 172 adults; (2) 35 postoperative gastric or colon cancer patients with indications for use of preventive intraperitoneal chemotherapy were infused with 1,000-1,250 mL 0.9 % normal saline solution for about 15 min and used for perfusate detection by moving along the midpoint of connecting line of two anterior superior spine after 5 min of infusion; (3) The VRP concentration in ascites was detected by liquid chromatography. RESULTS The distance between two anterior superior spines for adult were 29.6 ± 2.6 cm and the distance from the superior margin of pubic symphysis to the midpoint between two anterior superior spines was 10.6 ± 1.9 cm. When the total intraperitoneal infusion fluid was 1,000-1,250 mL, it could be detected by B-mode ultrasonic device at 0.1-0.3 cm directly below the midpoint of two anterior superior spines. The VRP reversal concentration of drug resistance could maintain for 90 min when the residual ascites volume was within the range of 1,000-1,250 mL. CONCLUSIONS Detection of liquid at the position directly below or above the midpoint of two anterior superior spines by B-mode ultrasonic device in patients in erect position could be a simple method for estimation of ascites volume (liquid found at 0.1-0.3 cm directly below the midpoint of two anterior superior spines suggested that ascites volume was smaller than 1,000-1,250 mL). The method could be used for determination of VRP initial concentration for IPC treatment.

Abstract
PURPOSE To assess the clinical efficacy of targeted arterial perfusion of verapamil and chemotherapeutic agents in the interventional therapy of lung cancer. METHODS Forty patients with advanced lung cancer underwent treatment with targeted arterial perfusion of verapamil and chemotherapeutic agents using Seldinger technique. Interventional therapy was performed once a month, and each subject received interventional treatment for 2 or more cycles. The therapeutic efficacy was evaluated 2 months post-treatment. RESULTS Out of 40 patients with advanced lung cancer, 5 cases achieved complete remission (CR) and 29 cases achieved partial remission (PR), with a total effectiveness (CR + PR) rate of 85 %. Besides, 32 cases achieved significantly alleviated clinical symptoms, and 29 cases had decreased clinical tumor stage. All subjects had stable karnofsky performance status score and body weight. Among the 40 patients, 13 cases had leucopenia, 10 cases had gastrointestinal reactions, 3 cases presented with elevated alanine aminotransferase/aspartate aminotransferase ratio, and 3 cases had fever. However, all these side effects relieved quickly. No elevation of BUN/Cr ratio and allergic reactions was observed. No significant changes in cardiac function and electrocardiogram were noticed after the treatment. CONCLUSIONS Targeted arterial perfusion of verapamil and chemotherapeutic drugs can improve the clinical symptoms of patients with advanced lung cancer and increase the efficacy of chemotherapeutic agents, thereby providing an opportunity for radiotherapy or surgical treatment for advanced lung cancer.

Abstract
OBJECTIVE To study the effects of methyl jasmonate on multidrug resistance in a mouse model of hepatocellular carcinoma. METHODS Multidrug resistant H22 (H22/FAP) hepatocellular carcinoma cells were produced in vitro by continuous exposure to increasing doses of doxorubicin, cisplatin and 5-fluorouracil (FAP regimen). Cell toxicity was measured using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolum bromide (MTT) assay. Survival time was calculated for BALB/c mice that received intraperitoneal injections of H22/FAP cells followed by treatment with methyl jasmonate or verapamil in combination with FAP for 7 days. Adenosine triphosphate (ATP) hydrolysis was used to measure the activity of permeability-glycoprotein (P-gp) ATPase activity in plasma membranes. RESULTS The MTT assay showed that methyl jasmonate significantly enhanced the cytotoxicity of the FAP regimen in multidrug resistant H22/FAP cells. Methyl jasmonate (10 mg/kg and 5 mg/kg) combined with FAP significantly increased survival time in BALB/c mice by 44.25% and 48.01%, respectively, compared with FAP. Methyl jasmonate increased P-gp ATPase activity. CONCLUSION The combined use of methyl jasmonate and the FAP regimen might be a novel strategy for overcoming the multidrug resistance often observed in hepatocellular carcinoma.

Abstract
The aim of this study was assess the therapeutic effect of targeted intra-arterial verapamil infusion in liver cancer patients and its side-effects in a dog model. The blood verapamil levels in dogs were determined after one-off intra-arterial infusion (0.7 mg/kg). Blood pressure, breathing state, and II-lead electrocardiogram were measured. Primary liver cancer patients (100) were randomly assigned into two groups. Controls (50) were treated with targeted intra-arterial infusion, and every patient received once-a-month interventional therapy, twice. Treatment group (50) received chemotherapeutics plus verapamil. Therapeutic and toxic side effects were evaluated. Control (41) and treatment group (45) patients were further treated with a second round of targeted intra-arterial infusion of chemotherapeutics plus verapamil, in 30 days after the 2-time interventional therapy. Every patient accepted interventional therapy 4-5 times during the 6 months after the first confirmed diagnosis. Following verapamil infusion, verapamil in dog liver was tenfold higher than in blood and was 4- to 20-fold higher than that needed for reversing carcinoma drug resistance. After interventional therapy, there were no significant changes in iconographic evaluation indices between the groups. Average activities of aminotransferases were 332 and 178 U/l in the treatment and control groups (P < 0.05). The imaging parameters of the treatment group were significantly better than those of control group. No side effects were found among the 91 patients who accepted verapamil infusion. After verapamil infusion, verapamil levels in dog hepatic tissue exceeded the effective concentration that reverses carcinoma multidrug resistance without any visible changes in the vital signs. Targeted intra-arterial verapamil infusion could improve the chemotherapy for the primary liver cancer patients without any side effects.
