Strategies to enhance the response of liver cancer to pharmacological treatments. Am J Physiol Cell Physiol 2024; 327:C11-C33. [PMID: 38708523 DOI: 10.1152/ajpcell.00176.2024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Revised: 04/26/2024] [Accepted: 04/26/2024] [Indexed: 05/07/2024]
Abstract
In contrast to other types of cancers, there is no available efficient pharmacological treatment to improve the outcomes of patients suffering from major primary liver cancers, i.e., hepatocellular carcinoma and cholangiocarcinoma. This dismal situation is partly due to the existence in these tumors of many different and synergistic mechanisms of resistance, accounting for the lack of response of these patients, not only to classical chemotherapy but also to more modern pharmacological agents based on the inhibition of tyrosine kinase receptors (TKIs) and the stimulation of the immune response against the tumor using immune checkpoint inhibitors (ICIs). This review summarizes the efforts to develop strategies to overcome this severe limitation, including searching for novel drugs derived from synthetic, semisynthetic, or natural products with vectorial properties against therapeutic targets to increase drug uptake or reduce drug export from cancer cells. Besides, immunotherapy is a promising line of research that is already starting to be implemented in clinical practice. Although less successful than in other cancers, the foreseen future for this strategy in treating liver cancers is considerable. Similarly, the pharmacological inhibition of epigenetic targets is highly promising. Many novel "epidrugs," able to act on "writer," "reader," and "eraser" epigenetic players, are currently being evaluated in preclinical and clinical studies. Finally, gene therapy is a broad field of research in the fight against liver cancer chemoresistance, based on the impressive advances recently achieved in gene manipulation. In sum, although the present is still dismal, there is reason for hope in the non-too-distant future.

Abstract
BACKGROUND The active-targeted drug delivery systems had attracted more and more attention to efficiently overcome multidrug resistance (MDR) in cancer treatments. The aim of the work was to develop a multifunctional nano-structured liposomal system for co-delivery of doxorubicin hydrochloride (DOX) and celecoxib (CEL) to overcome doxorubicin resistance in breast cancer. METHODS A functional hybrid peptide (MTS-R8H3) with unique cellular penetrability, endo-lysosomal escape and mitochondrial targeting ability was successfully synthesized using solid phase synthesis technology. The peptide modified targeted liposomes (DOX/CEL-MTS-R8H3 lipo) for co-delivery of DOX and CEL were formulated to overcome the chemoresistance in MCF/ADR cells. RESULTS DOX/CEL-MTS-R8H3 lipo showed nanosized shape and displayed high stability for one month. The cytotoxicity effect of the co-delivery of DOX and CEL through peptide modified liposomes had remarkable treatment efficacy on killing MCF/ADR cells. Targeted liposome exhibited greater cellular entry ability about 5.72-fold stronger than DOX solution. Moreover, as compared with unmodified liposomes, the presence of MTS-R8H3 peptide entity on liposome surface enhanced the mitochondrial-targeting ability and achieved effective reactive oxygen species (ROS) production with significant inhibition of P-gp efflux activity. CONCLUSION The study suggested that the DOX/CEL-MTS-R8H3 lipo is a promising strategy for overcoming drug resistance in breast cancer treatments with high targeting inhibition efficiency.

Celecoxib induces apoptosis through Akt inhibition in 5-fluorouracil-resistant gastric cancer cells. Toxicol Res 2021; 37:25-33. [PMID: 33489855 DOI: 10.1007/s43188-020-00044-3] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Revised: 02/10/2020] [Accepted: 03/04/2020] [Indexed: 10/24/2022] Open
Abstract
Gastric cancer is the fifth leading cause of cancer and a global public health problem. 5-Fluorouracil (5-FU) is the primary drug chosen for the treatment of advanced gastric cancer, but acquired cancer drug resistance limits its effectiveness and clinical use. Proliferation assays showed that a gastric carcinoma cell line, AGS and 5-FU-resistant AGS cells (AGS FR) treated with 3-100 μM 5-FU for 48 h or 72 h showed different sensitivities to 5-FU. Immunoblot assay demonstrated that AGS FR cells expressed more COX-2 and PGE2-cognated receptor EP2 than AGS cells. AGS FR cells considerably produced PGE2 than AGS upon stimulation with 5-FU. These results suggest that COX-2 expression is associated with 5-FU resistance. Unlike AGS FR cells, AGS cells showed increased levels of both cleaved caspase-3 and Bax following 5-FU treatment. Treatment of cells with the COX-2 selective inhibitor celecoxib induced cell death of AGS FR cells in a time- and concentration-dependent manner. FACS analysis showed that celecoxib at high doses caused apoptotic cell death, demonstrating a concentration-dependent increase in the cell populations undergoing early apoptosis and late apoptosis. This apoptotic induction was strongly supported by the expression profiles of apoptosis- and survival-associated proteins in response to celecoxib; pro-apoptotic cellular proteins increased while expressions of COX-2 and p-Akt were downregulated in a concentration-dependent manner. An increase in PTEN expression was accompanied with downregulation of p-Akt. Based on the data that downregulation of COX-2 was correlated with the concentrations of celecoxib, COX-2 may play a key role in celecoxib-induced cell death of AGS FR cells. Butaprost, the EP2 agonist, promoted proliferative activity of AGS FR cells in a concentration-dependent manner compared with AGS cells. In cells exposed to butaprost, expressions of COX-2 and p-Akt were increased in a concentration-dependent manner with concomitantly reduced PTEN levels. Taken together, 5-FU-resistance in gastric cancer is correlated with COX-2 expression, and therefore the selective inhibition of COX-2 leads to suppression of cell proliferation of AGS FR cells. Modulation of COX-2 expression and its catalytic activity may be a potential therapeutic strategy to overcome 5-FU-resistant gastric cancer.

Abstract
Emergence of novel treatment modalities provides effective therapeutic options, apart from conventional cytotoxic chemotherapy, to fight against colorectal cancer. Unfortunately, drug resistance remains a huge challenge in clinics, leading to invariable occurrence of disease progression after treatment initiation. While novel drug development is unfavorable in terms of time frame and costs, drug repurposing is one of the promising strategies to combat resistance. This approach refers to the application of clinically available drugs to treat a different disease. With the well-established safety profile and optimal dosing of these approved drugs, their combination with current cancer therapy is suggested to provide an economical, safe and efficacious approach to overcome drug resistance and prolong patient survival. Here, we review both preclinical and clinical efficacy, as well as cellular mechanisms, of some extensively studied repurposed drugs, including non-steroidal anti-inflammatory drugs, statins, metformin, chloroquine, disulfiram, niclosamide, zoledronic acid and angiotensin receptor blockers. The three major treatment modalities in the management of colorectal cancer, namely classical cytotoxic chemotherapy, molecular targeted therapy and immunotherapy, are covered in this review.

Abstract
AIM To evaluate the efficacy and safety of celecoxib combined with chemotherapy in the treatment of metastatic or postoperative recurrent gastric cancer. METHODS This preliminary, three-center, clinical trial study was conducted between September 2010 and December 2016. In the experimental group (n = 100), patients were treated with celecoxib combined with chemotherapy, and chemotherapy alone was used in the control group. Progression-free survival (PFS) was considered as the primary efficacy parameter. Overall survival (OS), remission rate (RR), quality of life (QOL) and drug safety were considered as the secondary efficacy parameters. RESULTS The PFS of the experimental group was 6 months, which was not significantly longer than that of the control group (5 months, P = .73). The average OS was not significantly different between the experimental group (12 months) and the control group (10 months, P = .59). The average OS of the COX-2 positive patients in the experimental group was 14 months and it was significantly longer than the 10-month OS in the control group (P = .01). The PFS of the COX-2 positive patients in the experimental group was 7.5 months, significantly longer than the 5-month PFS of patients in the control group (P < .001). No statistical significance was identified in the incidence of nausea, neutropenia, anorexia, peripheral neurotoxicity, diarrhea, vomiting, asthenia and thrombocytopenia. The EORTC QLQ-C30 questionnaire revealed that the overall QOL of the experimental group was significantly higher than that of the control group (P < .05). No statistical significance was found in the scores of functioning scale between the 2 groups. However, the scores of the symptom scale, especially for pain and fatigue in the experimental group was remarkably higher than that in the control group (P < .05). The overall score of EORTC QLQ-STO22 for the experimental group was considerably higher compared to that for the control group (P < .05). No statistical significance was identified in term of the domains of restrictions on feeding, dysphagia, anxiety, reflux, sense of taste, dry mouth, hair loss and body shape between the 2 groups (P > .05 for all mentioned outcomes). CONCLUSION Celecoxib combined with chemotherapy offers more clinical benefits for COX-2 positive advanced gastric cancer patients.

Abstract
This column is the third in a series exploring drug-drug interactions (DDIs) with a special emphasis on psychiatric medications. The first column in this series discussed why patients being treated with psychiatric medications are at increased risk for taking multiple medications and thus experiencing DDIs and how to recognize such DDIs, and strategies for avoiding them. The second column in the series further discussed strategies for avoiding and/or minimizing adverse outcomes from DDIs. This third column deals with pharmacokinetic considerations concerning DDIs in psychiatric practice. Specifically, this column discusses the 2 major types of pharmacokinetically mediated DDIs: those mediated by cytochrome P450 (CYP) enzymes and those mediated by transport proteins. The role of each of these regulatory proteins in the pharmacokinetics of drugs is reviewed as well as how genetically determined variation in the functional activity of these regulatory proteins can alter the accumulation of a drug in the body (ie, via CYP enzymes) and in specific compartments of the body (ie, via transport proteins), either increasing or decreasing their accumulation leading to either reduced efficacy or increased toxicity. This column further explains how coprescribed drugs can also affect the functional integrity of these regulatory proteins and lead to differences from usual in the accumulation of drugs dependent on the activity of these CYP enzymes and drug transporters. This phenomenon is known as phenoconversion in which a patient can functionally change from his or her genetic status, for example, having extensive or normal metabolism, to having poor or slow metabolism and hence greater accumulation than would be expected based on the patient's genotype.

Abstract
The evidence that cyclooxygenase-2 (COX-2) is upregulated and plays an important role in carcinogenesis of gastric cancer has triggered the topic of COX-2 inhibitors as chemopreventive agents for gastric cancer. Studies find that COX-2 inhibitors are associated not only with chemoprophylactic effects, but also with chemotherapeutic potentials in gastric cancer. Both COX-dependent and COX-independent pathways have a role in the anticancer efficiency of COX-2 inhibitors. However, enthusiasm is thwarted by the potential toxicity, that is, gastrointestinal toxicity of nonselective COX-2 inhibitors and cardiovascular risk of selective COX-2 inhibitors. Therefore, more studies are needed to develop new targeted antitumor agents (such as prostaglandin E receptor antagonist) and to define fundamental questions such as optimal treatment regimens, integration of cotherapy, and careful selection of candidates.

Abstract
UNLABELLED Devil's Claw (Harpagophytum procumbens) a plant native to Southern Africa, has historically been used in traditional medicine to treat a wide range of diseases and currently is widely employed as anti-inflammatory and pain-relieving natural remedy in Europe and other parts of the world. AIM OF THE STUDY Little is known about possible herb-drug interactions arising from effects of Devil's Claw on the major drug metabolizing enzymes or transporters. This study evaluated in vitro the effects of Devil's Claw on the multidrug transporter ABCB1/P-glycoprotein. MATERIALS AND METHODS The effects of three commercially available Devil's Claw preparations and that of pure harpagoside were studied in the human kidney (HK-2) proximal tubule cell line, constitutively expressing ABCB1/P-glycoprotein (P-gp). Pgp activity and expression were tested by the calcein-AM test and by Western blotting, respectively. RESULTS Commercial preparations inhibited P-gp activity, even if to a different extent, while pure harpagoside was almost ineffective. In cells cultured for three days in the presence of Devil's Claw preparations or pure harpagoside, a dose-dependent P-gp upregulation was found. CONCLUSIONS Our results demonstrate for the first time that Devil's Claw may interact with the multidrug transporter ABCB1/P-gp, the effect not appearing strictly related to the harpagoside relative content. Modulation of both P-gp activity and P-gp expression by Devil's Claw raise the possibility of herb-drug interactions, to be further explored in depth.

Abstract
FOLFOX is a cytostatic drug combination for adjuvant treatment of colorectal cancer (CRC) consisting of 5-fluorouracil (5-FU), leucovorin, and oxaliplatin. The mechanism of synergistic interaction of these drugs is poorly understood and little is known concerning the role of drug transporters and the impact of oxaliplatin metabolites oxalate and dichloro-diaminocyclohexane platinum. We therefore investigated the influence of FOLFOX components on drug transporter expression by quantitative real-time polymerase chain reaction and on the efficacy of each FOLFOX component by proliferation assay in the CRC model cell line LS180. Control experiments with transporter over-expressing cell lines were used to assess the significance of important transporters for the cytostatic activity of FOLFOX components. Moreover, we assessed the pharmacological contribution of the oxalato-ligand to the effect of oxaliplatin. FOLFOX components led to several alterations in expression of drug transporters. For instance, 5-FU significantly suppressed ATP7B and human organic cation transporter 2 and increased multidrug resistance-associated protein (MRP) 2 mRNA expression (5.8-fold). This was accompanied by a significant sensitisation to oxaliplatin. Over-expression of certain ABC-transporters (BCRP/ABCG2, MRP2/ABCC2 or MRP3/ABCC3) was demonstrated to be beneficial for the efficacy of oxaliplatin. The results obtained indicate that both down- and up-regulations of drug transporters could favour synergistic action of this drug combination. Moreover, oxaliplatin metabolite oxalate seems to positively modulate oxaliplatin's action as elucidated by median effect analysis. In conclusion, we propose as one mechanism for FOLFOX synergism the 5-FU mediated suppression of ATP7B, the over-expression of glutathione exporters such as MRP2/ABCC2 and the decrease of glutathione levels by oxalate.

Abstract
A series of icariin derivatives were synthesized. Their multidrug resistance (MDR) reversal activities were evaluated by MTT assay and the results indicated that the derivatives were the potent modulators of MDR. It was showed that the derivatives significantly increased the intracellular accumulation of ADR in MCF-7/ADR cells compared with drug sensitive MCF-7 cells. The results of bi-directional assay and reverse transcription polymerase chain reaction (RT-PCR) assay showed that the derivatives had high inhibitory activity against P-gp efflux function and significantly down-regulated on the expression of P-gp.

Abstract
The abnormal alternation of phosphatidylinositol-3-kinase/Protein Kinase B (PI3K/PKB) and cyclooxygenase-2 (COX-2) signal pathways plays an important role in emergence and development of tumors, which also contributes to a series of biological processes and exerts a tremendous influence on treatment and prognosis of tumors. This review investigates PI3K/Akt and COX-2 signal pathways blockage and their mechanism, and provided a original direction for molecular target therapy of diverse tumors including gastric carcinoma.
