Toxicon 2022; 217:112-120. [PMID: 35995098 DOI: 10.1016/j.toxicon.2022.08.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 08/01/2022] [Accepted: 08/08/2022] [Indexed: 12/24/2022]
Abstract
INTRODUCTION Wedelia trilobata (Sphagneticola trilobata) is a plant used in this popular medicine for treating infectious, sores and swellings in some rural communities, and their extract has antioxidant, anti-inflammatory, antitumor and hepatoprotective effect. Cancer is a molecularly heterogeneous disease caused by environmental and, genetic factors, among others. Since the complexity of the disease leads to low response rates to the different treatments used, it is necessary to find alternative drugs aimed at its control. The objective of our study was to assess whether grandiflorenic acid (GFA) has antitumor activity on breast (MCF7), liver (HuH7.5), and lung (A549) tumor cell lines. METHODS We used cell integrity assessment methods to assess whether (GFA) would be cytotoxic for tumor cell lines at doses ranging from and the pattern of death involved in this effect. RESULTS Treatment using GFA significantly inhibited cell proliferation in the three studied cells, followed by a decrease in cell size. The assessment of the death mechanisms showed the treatments increased the production of reactive oxygen species, caused exposure of phosphatidylserine, depolarization of the mitochondrial membrane, and, decrease plasma membrane integrity, indicating mechanisms related to apoptosis. Besides, we found the formation of autophagy vacuoles in our tests. CONCLUSION Finally, our study found the effect of GFA on breast (MCF7), lung (A549), and liver (HuH7.5) tumor cell lines induce cytotoxicity and patterns of death associated with apoptosis and autophagy, and oxidative stress generation plays a role in these two pathways of cell death. Thus, this study revealed GFA exhibits anti-cancer activity in vitro and could help future studies to improve strategies for cancer treatment with involving natural compounds.

Abstract
Simple Summary Cancer is a leading cause of death worldwide. While numerous studies have been conducted on cancer treatment, clinical treatment options for cancers are still limited. To date, animal cancer models for cancer therapeutic studies have faced multiple challenges, including inaccuracy in the representation of human cancers, high cost and ethical concerns. Therefore, lab-grown human cancer models are being developed quickly to fulfill the increasing demand for more relevant models in order to improve knowledge of human cancers and to find novel treatments. This review summarizes the development of lab-grown human cancer models for biomedical applications, including cancer therapeutic development, assessment of human tumor biology and discovery of key cancer markers. Abstract Cancer is one of the leading causes of death worldwide, and its incidence is steadily increasing. Although years of research have been conducted on cancer treatment, clinical treatment options for cancers are still limited. Animal cancer models have been widely used for studies of cancer therapeutics, but these models have been associated with many concerns, including inaccuracy in the representation of human cancers, high cost and ethical issues. Therefore, in vitro human cancer models are being developed quickly to fulfill the increasing demand for more relevant models in order to get a better knowledge of human cancers and to find novel treatments. This review summarizes the development of in vitro human cancer models for biomedical applications. We first review the latest development in the field by detailing various types of in vitro human cancer models, including transwell-based models, tumor spheroids, microfluidic tumor-microvascular systems and scaffold-based models. The advantages and limitations of each model, as well as their biomedical applications, are summarized, including therapeutic development, assessment of tumor cell migration, metastasis and invasion and discovery of key cancer markers. Finally, the existing challenges and future perspectives are briefly discussed.

Abstract
BACKGROUND Despite advancements in cancer treatment, breast cancer (BC) is still one of the leading causes of death among women. The majority of anti-breast-cancer medications induce serious side effects and multidrug resistance. Although several natural compounds, such as evening primrose oil (EPO), have been shown to have anticancer properties when used alone, their combination with the anticancer medicine tamoxifen (TAM) has yet to be investigated. The present study aimed to investigate the anticancer efficacy of EPO, alone or in combination with TAM, in the BC cell lines MCF-7 and MDA-MB-231, as well as to elucidate the mechanism of action. METHODS The MTT assay was used to investigate the cytotoxic effect of EPO on the two cell lines, and we discovered an acceptable IC50 that was comparable to TAM. The ELISA, qRT-PCR, flow cytometry and colorimetric techniques were used. RESULTS The combination of EPO and TAM suppressed the VEGF level, VEGF gene expression and Cyclin D1 signaling pathways, arrested the cell cycle, and induced the apoptotic signaling pathways by increasing the Bax/Bcl-2 ratio and caspase 3 activity; this revealed significant anti-tumor activity. CONCLUSIONS The most significant finding of this study was the confirmation of the anticancer activity of the natural product EPO, which potentiated the activity of the anticancer drug TAM against MCF-7 and MDA-MB-231 BC cell lines through the induction of apoptosis, inhibiting angiogenesis and halting cell proliferation.

Abstract
AIM This study aims to prepare green nanocomposite (HPMC/5-FL@GO) from the most biocompatible materials, hydroxypropyl methylcellulose (HPMC) and graphene oxide (GO), to enhance the drug activity of immobilized 5- Fluorouracil (5-FU) with decreasing the side effect of long-run treatment protocols with highly efficient drug-drug activity. METHOD AND RESULTS Different samples were characterized by ATR-FTIR spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM) coupled with energy dispersive X-ray analysis (EDX), transmission electron microscopy (TEM), Thermogravimetric analysis (TGA), and dynamic light scattering (DLS) along with cytotoxicity and anticancer study. A homogenous and compatible nanocomposite structure with a homogenous drug distribution was confirmed. The results suggested that the prepared nanocomposite has a low cytotoxicity effect against normal Vero cell lines compared with 5-FU. The antitumor activities of the same nanocomposite (20.4 and 74.3 μg/ml on A549 and HepG-2) were lower than that of 5-FU (54.1and 103 μg/ml on A549 and HepG-2). CONCLUSION AND IMPLICATIONS According to the attained results, the HPMC/5-FL@GO can be expected to be widely applied in a biomedical application such as cancer therapy with the unique biocompatible to human cells.

Abstract
In this study, Egyptian beebread (EBB) was investigated for its nutritive value, chemical composition, antioxidant properties, antimicrobial and antitumor activities. Results indicated that EBB was a good source of protein (23.58 ± 0.183 g/100 g BB), total free sugar (20.266 ± 0.930) and potassium (290.202 ± 2.645 mg/100 g). Additionally, 14 fatty acids were identified in EBB, wherein polyunsaturated and monounsaturated fatty acids represented 51.06% ± 0.09% and 9.86% ± 0.01%, respectively. The EBB extract exhibited almost 400% better antiradical activity than BHT, with IC50 of EBB extract being 10.7 µg/mL compared to 39.5 µg/mL for BHT. EBB exhibited higher inhibitory activity than the reference compound against Staphylococcus aureus and Escherichia coli, followed by Bacillus subtilis. No inhibitory activity was observed against Aspergillus Niger. Additionally, the highest inhibitory activity was recorded against Caco-2 cells, followed by PC3 and HepG-2 cancer cell lines with IC50 values 262, 314 and 386 μg/mL, respectively. These findings establish the potential of EBB as an antioxidant, antimicrobial and antitumor agent, with possible applications as natural food supplements and natural preservatives.

Abstract
Omega-3 polyunsaturated fatty acid (ω-3 PUFA) supplements for chemoprevention of different types of cancer including lung cancer has been investigated in recent years. ω-3 PUFAs are considered immunonutrients, commonly used in the nutritional therapy of cancer patients. ω-3 PUFAs play essential roles in cell signaling and in cell structure and fluidity of membranes. They participate in the resolution of inflammation and have anti-inflammatory effects. Lung cancer patients suffer complications, such as anorexia-cachexia syndrome, pain and depression. The European Society for Clinical Nutrition and Metabolism (ESPEN) 2017 guidelines for cancer patients only discuss the use of ω-3 PUFAs for cancer-cachexia treatment, leaving aside other cancer-related complications that could potentially be managed by ω-3 PUFAs. This review aims to elucidate whether the effects of ω-3 PUFAs in lung cancer is supplementary, pharmacological or both. In addition, clinical studies, evidence in cell lines and animal models suggest how ω-3 PUFAs induce anticancer effects. ω-3 PUFAs and their metabolites are suggested to modulate pivotal pathways underlying the progression or complications of lung cancer, indicating that this is a promising field to be explored. Further investigation is still required to analyze the benefits of ω-3 PUFAs as supplementation or pharmacological treatment in lung cancer.

Abstract
Vulvar squamous cell carcinoma associated with lichen sclerosus (VLS-VSCC) are rare tumors but with higher recurrence and worse prognosis than other types of VSCC. Lack of experimental models has limited the search for better understanding of the biology and development of treatment modalities. In this study, we isolated and characterized primary cells from VSCC (n = 7) and normal vulvar tissue adjacent to tumor (n = 7). Detailed characterization of the novel spontaneously immortalized cell line, VCC1 revealed a characteristic epithelial morphology in vitro and a well-differentiated keratinizing SCC histology in vivo, closely resembling the tumor of origin. VCC1 expressed higher levels of epithelial-mesenchymal transition markers and higher clonogenic properties as compared to other established non VLS-VSCC cell lines. In vitro 3D organotypic assays and in vivo xenografts revealed a prominent role of cancer-associated fibroblasts in VCC1 invasion and tumor formation. In conclusion, VCC1 mirrored several major VLS-VSCC features and provided a robust experimental tool for further elucidation of VLS-related oncogenesis and drug testing.

Abstract
Steroidal hormones progesterone and testosterone play a vital role in breast and prostate cancers. In this research, we have synthesized and characterized a total of thirty-one (31) new nitrogenous derivatives of progesterone and testosterone. The synthesized derivatives (1-31) were screened for their anti-cancer potential against MCF-7 and PC-3 cell lines of breast using MTT assay. The compounds 1-31exhibited significant inhibitory potentials against MCF-7 and PC-3 cell lines. In MCF-7 assay, compound 17 displayed IC50 value of 04 ± 0.02 μM while compound 18 was leading in PC-3 assay with IC50 of 03.14 ± 0.4 μM. Tamoxifen was used as positive control which exhibited an IC50of 0.12 ± 0.03 and 0.26 ± 0.01 μM against MCF-7 and PC-3 respectively. The compounds also showed good anti-inflammatory activity according to oxidative burst inhibition by chemiluminescence technique where ibuprofen was used as positive control with 73.2 ± 1.4% ROS inhibition. The compounds showed the percent ROS inhibition between 23.2 ± 0.2 and -3.2 ± 4.1. The results of the compounds were compared with the positive control ibuprofen. Molecular docking correlations suggest that the compounds exerted their inhibitory activity by binding to the active of the enzyme.

Abstract
Biological effects of rutin bioactive are limited due to its poor oral bioavailability and its degradation in aqueous environments. For the purpose of bioenhancement, different nanoemulsion systems of rutin were developed by aqueous titration method using water as dispersion media. The nanoemulsion systems were characterized for surface morphology, droplet size, polydispersity index, zeta potential, in vitro release profile and the formulations were optimized. The anticancer potential of optimized nanoemulsion was evaluated by cells viability (MTT) assay, nuclear condensation, and ROS activity using human prostate cancer (PC3) cell line. On the basis of cell viability data the inhibitory concentration (IC50) value for optimized nanoemulsion formulation on PC3 cancer cells was found to be 11.8 μM. Fluorescent microscopic analysis and intracellular ROS generation demonstrated significant ROS induction that might lead to triggering the apoptosis pathway. In conclusion, developed nanoemulsion displayed significant efficacy against prostate carcinoma cells.

Abstract
The records are not clear, but Man has been sheltering the cat inside his home for over 12,000 years. The close proximity of this companion animal, however, goes beyond sharing the same roof; it extends to the great similarity found at the cellular and molecular levels. Researchers have found a striking resemblance between subtypes of feline mammary tumors and their human counterparts that goes from the genes to the pathways involved in cancer initiation and progression. Spontaneous cat mammary pre-invasive intraepithelial lesions (hyperplasias and neoplasias) and malignant lesions seem to share a wide repertoire of molecular features with their human counterparts. In the present review, we tried to compile all the genetics aspects published (i.e., chromosomal alterations, critical cancer genes and their expression) regarding cat mammary tumors, which support the cat as a valuable alternative in vitro cell and animal model (i.e., cat mammary cell lines and the spontaneous tumors, respectively), but also to present a critical point of view of some of the issues that really need to be investigated in future research.

A comprehensive characterization of cell cultures and xenografts derived from a human verrucous penile carcinoma. Tumour Biol 2016; 37:11375-84. [PMID: 26960831 DOI: 10.1007/s13277-016-4951-z] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2015] [Accepted: 01/29/2016] [Indexed: 12/15/2022] Open
Abstract
This study aimed to establish and characterize primary cell cultures and xenografts derived from penile carcinoma (PeCa) in order to provide experimental models for cellular processes and efficacy of new treatments. A verrucous squamous cell carcinoma (VSCC) was macrodissected, dissociated, and cultivated in KSFM/DF12 medium. Cell cultures were evaluated at passage 5 (P5) using migration and invasion assays and were serially propagated, in vivo, in BALB/c nude mice until passage 3 (X1-X3). Immunophenotypic characterization of cultures and xenografts was performed. Genomic (CytoScan HD, Affymetrix) and transcriptomic profiles (HTA 2.0 platform, Affymetrix) for VSCC, cell cultures, and xenografts were assessed. P5 cells were able to migrate, invade the Matrigel, and produce tumors in immunodeficient mice, demonstrating their malignant potential. The xenografts unexpectedly presented a sarcomatoid-like carcinoma phenotype. Genomic analysis revealed a high similarity between the VSCC and tumor-derived xenograft, confirming its xenograft origin. Interestingly, a subpopulation of P5 cells presented stem cell-related markers (CD44(+)CD24(-) and ALDH1(high)) and sphere-forming capacity, suggesting their potential xenograft origin. Cell cultures and xenografts retained the genomic alterations present in the parental tumor. Compared to VSCC, differentially expressed transcripts detected in all experimental conditions were associated with cellular morphology, movement, and metabolism and organization pathways. Malignant cell cultures and xenografts derived from a verrucous penile carcinoma were established and fully characterized. Nevertheless, xenograft PeCa models must be used with caution, taking into consideration the selection of specific cell populations and anatomical sites for cell/tumor implantation.

Abstract
Studies on tumours in domestic animals are believed to greatly contribute to a better understanding of similar diseases in humans. Comparative studies have shown that feline mammary carcinomas share important features with human breast cancers, including a similar biological behaviour and histological appearance. In the present study we have established and characterized at different cellular levels one feline mammary cancer cell line, FkMTp, derived from a cat mammary carcinoma. The FkMTp cell line revealed to be a promising resource and tool to study tumour microevolution and all the mechanisms and processes involved in carcinogenesis from the tumour (primary culture) to the immortalized cell line. Several assays were conducted to assess the growth behaviour, differentiated morphology, anchorage independent growth in soft agar, wound-healing invasion and migration of the cell line across time (from the primary culture until the 160th passage). FkMTp revealed increased levels of anchorage independence, migration and invasion according to the course of time as well as different numbers of ploidy. These results demonstrate and validate the in vitro tumorigenicity of the FkMTp cell line. During the cell line establishment, it was cryopreserved approximately every six passages, including the tumour primary culture, allowing now the possibility to access almost any specific momento of the tumour progression.

Abstract
During the past four decades, an increased number of similarities between canine mammary tumors and human breast cancer have been reported: molecular, histological, morphological, clinical and epidemiological, which lead to comparative oncological studies. One of the most important goals in human and veterinary oncology is to discover potential molecular biomarkers that could detect breast cancer in an early stage and to develop new effective therapies. Recently, cancer cell lines have successfully been used as an in vitro model to study the biology of cancer, to investigate molecular pathways and to test the efficiency of anticancer drugs. Moreover, establishment of an experimental animal model for the study of human breast cancer will improve testing potential anti-cancer therapies and the discovery of effective therapeutic schemes suitable for human clinical trials. In this review, we collected data from previous studies that strengthen the value of canine mammary cancer cell lines as an in vitro model for the study of human breast cancer.

Abstract
Breast cancer is a complex and heterogeneous disease, and the establishment of cell models in order to properly study the disease at the molecular and cellular level is of utmost importance. Here, we present the cytogenetic characterization and gene expression analysis of the tumoral mammary rat cell line CLS-ACI-1. The use of banding and molecular cytogenetic techniques allowed the description of the complex CLS-ACI-1 karyotype and the identification of breakpoints in clonal chromosome rearrangements. Moreover, a Mycn and Erbb2 comparative expression analysis by RT-qPCR was performed, revealing a high expression level of Mycn in CLS-ACI-1 cells. Moreover, a considerable number of putative mutated genes and chromosome alterations detected through cytogenetic analysis seem to be in the MYCN biological network. Therefore, the CLS-ACI-1 cell line is presented as a promising cell model for the study of the role of MYCN in breast cancer and also as a tool for developing appropriate cancer therapies, namely for Mycn targeting.

Abstract
Background Canine mammary tumors (CMTs) are the most common type of cancer found in female dogs. Establishment and evaluation of tumor cell lines can facilitate investigations of the biological mechanisms of cancer. Different cell models are used to investigate genetic, epigenetic, and cellular pathways, cancer progression, and cancer therapeutics. Establishment of new cell models will greatly facilitate research in this field. In the present study, we established and characterized two new CMT cell lines derived from a single CMT. Results We established two cell lines from a single malignant CMT specimen: DTK-E and DTK-SME. Morphologically, the DTK-E cells were large, flat, and epithelial-like, whereas DTK-SME cells were round and epithelial-like. Doubling times were 24 h for DTK-E and 18 h for DTK-SME. On western blots, both cell lines expressed cytokeratin AE1, vimentin, cytokeratin 7 (CK7), and heat shock protein 27 (HSP27). Moreover, investigation of chemoresistance revealed that DTK-SME was more resistant to doxorubicin-induced apoptosis than DTK-E was. After xenotransplantation, both DTK-E and DTK-SME tumors appeared within 14 days, but the average size of DTK-SME tumors was greater than that of DTK-E tumors after 56 days. Conclusion We established two new cell lines from a single CMT, which exhibit significant diversity in cell morphology, protein marker expression, tumorigenicity, and chemoresistance. The results of this study revealed that the DTK-SME cell line was more resistant to doxorubicin-induced apoptosis and exhibited higher tumorigenicity in vivo than the DTK-E cell line. We anticipate that the two novel CMT cell lines established in this study will be useful for investigating the tumorigenesis of mammary carcinomas and for screening anticancer drugs.

Abstract
The combination of transcriptomic analysis and fluorescence in situ hybridization (FISH) provides a robust methodology to study genomic changes in different biological conditions. Microarrays allow a global study of gene expression in response to the conditions of interest, with comparison between control(s) and one or more test condition(s). The messenger RNA amplification step permits detection of even low abundance transcripts, a critical advantage for applications such as biomaterials research, where the starting material may be limited. Different types of microarrays are commercially available that allow the investigation of specific features, such as exon arrays, microRNA arrays, and gene arrays. Microarrays are available for different model organisms, but we use Affymetrix ® HuGene ® ST (Sense Target) arrays, a type of gene array for analysis of human samples. FISH involves fluorescent detection of probe DNA hybridized to an in situ chromosomal target that can be either whole chromosomes or chromosomal segments. The overall hybridization is similar to labeling with radioactive probes but the incorporation of fluorescent detection of the probe sequences allows for high sensitivity in a simple and quick assay. FISH can be applied to a variety of specimen types depending on the study of interest. In this chapter, we describe the methodologies of these two techniques and provide technical tips that should help overcome challenges in carrying them out.

Abstract
The standing outward K(+) current (IKso) governs the response of cerebellar granule neurons to natural and medicinal stimuli including volatile anesthetics. We showed that SUMOylation silenced half of IKso at the surface of cerebellar granule neurons because the underlying channels were heterodimeric assemblies of K2P1, a subunit subject to SUMOylation, and the TASK (two-P domain, acid-sensitive K(+)) channel subunits K2P3 or K2P9. The heterodimeric channels comprised the acid-sensitive portion of IKso and mediated its response to halothane. We anticipate that SUMOylation also influences sensation and homeostatic mechanisms in mammals through TASK channels formed with K2P1.
