Balaha M, De Filippis B, Cataldi A, di Giacomo V. CAPE and Neuroprotection: A Review. Biomolecules 2021; 11:biom11020176. [PMID: 33525407 PMCID: PMC7911454 DOI: 10.3390/biom11020176] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 01/15/2021] [Accepted: 01/25/2021] [Indexed: 12/13/2022] Open
Abstract
Propolis, a product of the honey bee, has been used in traditional medicine for many years. A hydrophobic bioactive polyphenolic ester, caffeic acid phenethyl ester (CAPE), is one of the most extensively investigated active components of propolis. Several studies have indicated that CAPE has a broad spectrum of pharmacological activities as anti-oxidant, anti-inflammatory, anti-viral, anti-fungal, anti-proliferative, and anti-neoplastic properties. This review largely describes CAPE neuroprotective effects in many different conditions and summarizes its molecular mechanisms of action. CAPE was found to have a neuroprotective effect on different neurodegenerative disorders. At the basis of these effects, CAPE has the ability to protect neurons from several underlying causes of various human neurologic diseases, such as oxidative stress, apoptosis dysregulation, and brain inflammation. CAPE can also protect the nervous system from some diseases which negatively affect it, such as diabetes, septic shock, and hepatic encephalopathy, while numerous studies have demonstrated the neuroprotective effects of CAPE against adverse reactions induced by different neurotoxic substances. The potential role of CAPE in protecting the central nervous system (CNS) from secondary injury following various CNS ischemic conditions and CAPE anti-cancer activity in CNS is also reviewed. The structure–activity relationship of CAPE synthetic derivatives is discussed as well.

Int J Oncol 2020; 57:161-170. [PMID: 32377719 PMCID: PMC7252454 DOI: 10.3892/ijo.2020.5053] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2019] [Accepted: 02/28/2020] [Indexed: 12/15/2022] Open
Abstract
Optimizing the currently available treatment options for pancreatic cancer (PC) is a priority. Cabazitaxel (CTX), a semisynthetic taxane, is mainly used for treating patients with PC who are resistant to paclitaxel (PTX) or docetaxel, due its poor affinity for P-glycoprotein. However, there are only a few studies demonstrating the effect of CTX on PC. The present study aimed to investigate the efficiency and underlying mechanism of CTX in PC treatment. Cell proliferation, colony formation assay and apoptosis analysis were achieved in the two human PC cell lines AsPC-1 and BxPC-3. Drug sensitivity test was performed in BxPC-3 tumor-bearing mice. The results demonstrated that CTX had a lower half maximal inhibitory concentration compared with PTX for the inhibition of cell proliferation, both in vivo and in vitro. Furthermore, the nuclear factor-κB (NF-κB) pathway was activated following cell treatment with CTX, and NF-κB p65 overexpression attenuated CTX cytotoxicity. In addition, the combined use of the specific NF-κB inhibitor caffeic acid phenethyl ester (CAPE) with CTX significantly enhanced CTX effect, both in vivo and in vitro. Similarly, the mRNA and protein expression of B-cell lymphoma-2 was decreased in AsPC-1 and BxPC-3 cells following treatment with CTX and CAPE, suggesting that NF-κB may serve a crucial role in CTX efficiency. In conclusion, results from our previous study indicated that CTX could potentially replace PTX in the treatment of PC, and the present study demonstrated that CTX combination with an NF-κB inhibitor may be considered as a potential therapeutic option for PC, which may improve the prognosis of patients with PC.

Abstract
The phospholipase D (PLD) family has a ubiquitous expression in cells. PLD isoforms (PLDs) and their hydrolysate phosphatidic acid (PA) have been demonstrated to engage in multiple stages of cancer progression. Aberrant expression of PLDs, especially PLD1 and PLD2, has been detected in various cancers. Inhibition or elimination of PLDs activity has been shown to reduce tumour growth and metastasis. PLDs and PA also serve as downstream effectors of various cell-surface receptors, to trigger and regulate propagation of intracellular signals in the process of tumourigenesis and metastasis. Here, we discuss recent advances in understanding the functions of PLDs and PA in discrete stages of cancer progression, including cancer cell growth, invasion and migration, and angiogenesis, with special emphasis on the tumour-associated signalling pathways mediated by PLDs and PA and the functional importance of PLDs and PA in cancer therapy.

Int J Mol Sci 2020; 21:ijms21041282.

Abstract
In this study, we aimed to elucidate the anti-invasive effects of Cudrania tricuspidata root-gold nanoparticles (CTR-GNPs) using glioblastoma cells. We demonstrated the rapid synthesis of CTR-GNPs using UV-vis spectra. The surface morphology, crystallinity, reduction, capsulation, and stabilization of CTR-GNPs were analyzed using high resolution transmission electron microscopy (HR-TEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FT-IR). Furthermore, CTR-GNPs displayed excellent photocatalytic activity as shown by the photo-degradation of methylene blue and rhodamine B. Cell migration and invasion assays with human glioblastoma cells were performed to investigate the anti-invasive effect of CTR-GNPs on U87 cells that were treated with phorbol 12-myristate 13-acetate. The results show that CTR-GNPs can significantly inhibit both basal and phorbol 12-myristate 13-acetate (PMA)-induced migration and invasion ability. Importantly, treatment with CTR-GNPs significantly decreased the levels of metalloproteinase (MMP)-2/-9 and phospholipase D1 (PLD1) and protein but not PLD2, which is involved in the modulation of migration and the invasion of glioblastoma cells. These results present a novel mechanism showing that CTR-GNPs can attenuate the migration and invasion of glioblastoma cells induced by PMA through transcriptional and translational regulation of MMP-2/-9 and PLD1. Taken together, our results suggest that CTR-GNPs might be an excellent therapeutic alternative for wide range of glioblastomas.

Abstract
Introduction: Up-regulation of phospholipase D (PLD) is functionally related to tumorigenesis and oncogenic signals. Chrysin, caffeic acid phenethyl ester (CAPE) and ethanolic extract of propolis (EEP) are three safe compounds which have been shown to possess antiproliferative, antioxidant, anti-inflammatory and antineoplastic properties. In this study, the effects of these three compounds on PLD1 gene expression were examined in AGS cell line. Methods: After determining the appropriate concentrations of EEP, CAPE, and chrysin, AGS cells were cultured in mediums with proper ratios of the compounds. AGS cells were maintained in exponential growth and the culture mediums refreshed every other day. Finally, after extracting total RNA from AGS cells, real-time PCR was performed to evaluate the mRNA expression of PLD1 in the presence of each compound. Results: CAPE decreased the mRNA level of PLD1 gene in a dose-dependent manner. A solution with 30 μM concentration of CAPE was the effective dose in comparison to control group as well as 15 and 20 μM concentrations of the compound, whereas no changes were observed in the presence of EEP and chrysin. Conclusion: Taken together, the results of the study indicated that CAPE might exert its anti-neoplastic effect by targeting PLD1 expression in AGS cell line.

Abstract
Lipids are key building blocks of biological membranes and are involved in complex signaling processes such as metabolism, proliferation, migration, and apoptosis. Extracellular signaling by growth factors, stress, and nutrients is transmitted through receptors that activate lipid-modifying enzymes such as the phospholipases, sphingosine kinase, or phosphoinositide 3-kinase, which then modify phospholipids, sphingolipids, and phosphoinositides. One such important enzyme is phospholipase D (PLD), which cleaves phosphatidylcholine to yield phosphatidic acid and choline. PLD isoforms have dual role in cells. The first involves maintaining cell membrane integrity and cell signaling, including cell proliferation, migration, cytoskeletal alterations, and invasion through the PLD product PA, and the second involves protein-protein interactions with a variety of binding partners. Increased evidence of elevated PLD expression and activity linked to many pathological conditions, including cancer, neurological and inflammatory diseases, and infection, has motivated the development of dual- and isoform-specific PLD inhibitors. Many of these inhibitors are reported to be efficacious and safe in cells and mouse disease models, suggesting the potential for PLD inhibitors as therapeutics for cancer and other diseases. Current knowledge and ongoing research of PLD signaling networks will help to evolve inhibitors with increased efficacy and safety for clinical studies.

Immunoregulation by IL-7R-targeting antibody-drug conjugates: overcoming steroid-resistance in cancer and autoimmune disease. Sci Rep 2017; 7:10735.

Abstract
Steroid-resistance is a common complication in the treatment of malignancies and autoimmune diseases. IL-7/IL-7R signaling, which regulates lymphocyte growth and survival, has been implicated in the development of malignancies and autoimmune diseases. However, the biological significance of IL-7/IL-7R signaling in steroid treatment is poorly understood. Here, we identified a novel relationship between IL-7R signaling and steroid-resistance, and showed that an anti-IL-7R antibody conjugated with SN-38 (A7R-ADC-SN-38) has strong anti-tumor effects against both parental and steroid-resistant malignant cells. Furthermore, inflammation in the mouse autoimmune arthritis model was suppressed to greater extent by A7R-ADC conjugated to MMAE than by A7R-ADC-SN-38. Given that an increased proportion of IL-7R-positive cells is a common mechanism underlying the pathogenesis of autoimmunity, we found that specific depletion of this cell population abrogated the progression of disease. This suggests that the cytotoxicity and immunosuppressive capacity of A7R-ADC could be modulated to treat specific malignancies or autoimmune diseases through the introduction of different payloads, and represents a novel alternative to steroid therapy.

Abstract
Mesalazine (5-aminosalicylic acid, 5-ASA), a currently used drug for anti-inflammatory bowel disease, is easily oxidized by HOCl, a strong oxidant generated in gut inflammation, to produce electrophilic quinones. We investigated whether this chemical feature has an implication in the anti-inflammatory pharmacology of 5-ASA. Human colon carcinoma HCT116 cells were treated with HOCl-reacted 5-ASA. Oxidized 5-ASA activated Nrf2 while 5-ASA itself was not effective. Activation of Nrf2 led to induction of hemeoxygenase (OH)-1, an anti-inflammatory enzyme. Western blot analysis of Keap1, a cytosolic repressor of Nrf2, following precipitation of biotin-labeled proteins in cell lysates treated with biotin-tagged 5-ASA, revealed a much greater amount of Keap1 when biotin-tagged 5-ASA was oxidized with HOCl. Precipitation of Keap1 was attenuated markedly by pretreatment with oxidized 5-ASA or a sulfhydryl donor. In addition, treatment with oxidized 5-ASA in cell lysates reduced the Keap1 amount that coimmunoprecipitated with Nrf2. In parallel, rectal administration of 5-ASA increased the level of HO-1 and nuclear Nrf2 in the inflamed colonic tissues, but not in normal colonic tissues. Moreover, oral gavage of sulfasalazine, a colon-specific prodrug of 5-ASA currently used clinically, activated the Nrf2-HO-1 pathway in the colonic tissues where inflammation was in progress, which was not observed when inflammation subsided. Collectively, our data suggest that Nrf2-HO-1 pathway is involved in the anti-inflammatory pharmacology of 5-ASA, which was likely being exerted exclusively in the inflammatory state.

Abstract
Caffeic acid phenethyl ester (CAPE), a naturally occurring compound isolated from propolis extract, has been reported to have a number of biological and pharmacological properties, exerting antioxidant, anti-inflammatory, anticarcinogenic, antibacterial and immunomodulatory effects. Recent in vivo and in vitro study findings have provided novel insights into the molecular mechanisms involved in the anti-inflammatory and immunomodulatory activities of this natural compound. CAPE has been reported to have anti-inflammatory properties involving the inhibition of certain enzyme activities, such as xanthine oxidase, cyclooxygenase and nuclear factor-κB (NF-κB) activation. Since inflammation and immune mechanisms play a crucial role in the onset of several inflammatory diseases, the inhibition of NF-κB represents a rationale for the development of novel and safe anti-inflammatory agents. The primary goal of the present review is to highlight the anti-inflammatory and immunomodulatory activities of CAPE, and critically evaluate its potential therapeutic effects.

Abstract
Phospholipase D (PLD) regulates downstream effectors by generating phosphatidic acid. Growing links of dysregulation of PLD to human disease have spurred interest in therapeutics that target its function. Aberrant PLD expression has been identified in multiple facets of complex pathological states, including cancer and inflammatory diseases. Thus, it is important to understand how the signaling network of PLD expression is regulated and contributes to progression of these diseases. Interestingly, small molecule PLD inhibitors can suppress PLD expression as well as enzymatic activity of PLD and have been shown to be effective in pathological mice models, suggesting the potential for use of PLD inhibitors as therapeutics against cancer and inflammation. Here, we summarize recent scientific developments regarding the regulation of PLD expression and its role in cancer and inflammatory processes.
