[PMID: 34576262 PMCID: PMC8469885 DOI: 10.3390/ijms221810103] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 09/11/2021] [Accepted: 09/15/2021] [Indexed: 12/24/2022] Open
Abstract
Cannabidiol (CBD), a nonpsychoactive phytocannabinoid, has recently emerged as a potential cytotoxic agent in addition to its ameliorative activity in chemotherapy-associated side effects. In this work, the potential interactions of CBD with docetaxel (DOC), doxorubicin (DOX), paclitaxel (PTX), vinorelbine (VIN), and 7-ethyl-10-hydroxycamptothecin (SN-38) were explored in MCF7 breast adenocarcinoma cells using different synergy quantification models. The apoptotic profiles of MCF7 cells after the treatments were assessed via flow cytometry. The molecular mechanisms of CBD and the most promising combinations were investigated via label-free quantification proteomics. A strong synergy was observed across all synergy models at different molar ratios of CBD in combination with SN-38 and VIN. Intriguingly, synergy was observed for CBD with all chemotherapeutic drugs at a molar ratio of 636:1 in almost all synergy models. However, discording synergy trends warranted the validation of the selected combinations against different models. Enhanced apoptosis was observed for all synergistic CBD combinations compared to monotherapies or negative controls. A shotgun proteomics study highlighted 121 dysregulated proteins in CBD-treated MCF7 cells compared to the negative controls. We reported the inhibition of topoisomerase II β and α, cullin 1, V-type proton ATPase, and CDK-6 in CBD-treated MCF7 cells for the first time as additional cytotoxic mechanisms of CBD, alongside sabotaged energy production and reduced mitochondrial translation. We observed 91 significantly dysregulated proteins in MCF7 cells treated with the synergistic combination of CBD with SN-38 (CSN-38), compared to the monotherapies. Regulation of telomerase, cell cycle, topoisomerase I, EGFR1, protein metabolism, TP53 regulation of DNA repair, death receptor signalling, and RHO GTPase signalling pathways contributed to the proteome-wide synergistic molecular mechanisms of CSN-38. In conclusion, we identified significant synergistic interactions between CBD and the five important chemotherapeutic drugs and the key molecular pathways of CBD and its synergistic combination with SN-38 in MCF7 cells. Further in vivo and clinical studies are warranted to evaluate the implementation of CBD-based synergistic adjuvant therapies for breast cancer.

Res Vet Sci 2020; 133:157-162. [PMID: 32992127 DOI: 10.1016/j.rvsc.2020.09.018] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Revised: 09/17/2020] [Accepted: 09/17/2020] [Indexed: 11/27/2022]
Abstract
For the current European legislation, the chemical analysis of drug residues is the exclusive accepted method to identify animals illicitly treated with growth promoters. Glucocorticoids and their metabolites are no detectable by LC/MS-MS methods in biological fluids when the growth promoter administration is discontinued several days prior to the slaughtering. The aim of this study was to elucidate the effect on the expression of genes belonging to the glucocorticoid pathway in three types of skeletal muscle of calves treated with prednisolone or dexamethasone in combination with estradiol. A gene expression change of glucocorticoid receptors (NR3C1 and NR3C2), their chaperones molecules (FKBP prolyl isomerase 4 and 5, FKBP4 and 5) and pre-receptor system (hydroxysteroid 11-beta dehydrogenases 1 and 2, HSD11B1 and 2) may indicate potential biomarkers of glucocorticoid treatment. In the biceps brachii muscle, the administration of dexamethasone with estradiol increased HSD11B2 (P < 0.01) and NR3C2 (P < 0.01) gene expression, whereas prednisolone administration increased HSD11B1 transcript levels (P < 0.05). In the longissimus lumborum muscle, NR3C2 gene expression decreased following prednisolone administration (P < 0.05). FKBP5 gene expression decreased in all considered muscles of calves administered with dexamethasone and estradiol (P < 0.01), whereas increased in the longissimus lumborum (P < 0.01) and vastus lateralis (P < 0.05) muscle of prednisolone-treated group (P < 0.05). The opposite effect of dexamethasone and prednisolone appears very promising to develop a low-cost screening test, because the expression analysis of a unique gene in a given tissue may distinguish the dispensed molecules.

Expression of corticosteroid hormone receptors, prereceptors, and molecular chaperones in hypothalamic-pituitary-adrenal axis and adipose tissue after the administration of growth promoters in veal calves. Domest Anim Endocrinol 2020; 72:106473. [PMID: 32361423 DOI: 10.1016/j.domaniend.2020.106473] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Revised: 02/14/2020] [Accepted: 03/01/2020] [Indexed: 02/08/2023]
Abstract
The action of glucocorticoids on target tissues is regulated by the glucocorticoid and mineralocorticoid receptors (codified by the NR3C1 and NR3C2 gene, respectively). Moreover, the prereceptor system, represented by the hydroxysteroid 11-beta dehydrogenases (HSD11Bs), catalyzes the interconversion from active glucocorticoids into inactive compounds. This study aimed to determine whether the expression of the prereceptor system, the corticosteroid receptors, and the molecules regulating their intracellular trafficking (FKBP prolyl isomerase 4 and FKBP prolyl isomerase 5) could be regulated in the hypothalamic-pituitary-adrenal axis and in different type of adipose tissue of calves by the administration of dexamethasone in combination with estradiol or prednisolone. Research about the glucocorticoid effects on bovine target tissues may allow development of new diagnostic methods that use potential molecular biomarkers of glucocorticoid treatment. The administration of dexamethasone in combination with estradiol increased the gene expression of HSD11B1 (P < 0.01), HSD11B2 (P < 0.05), NR3C1 (P < 0.01), and NR3C2 (P < 0.01) in the adrenal glands; NR3C2 in the intramuscular adipose tissue (P < 0.01), and HSD11B1 in the subcutaneous adipose tissue (P < 0.01). Prednisolone administration increased the gene expression of HSD11B1 (P < 0.01), NR3C1 (P < 0.05), and NR3C2 (P < 0.05) in the adrenal glands and HSD11B1 (P < 0.01) in the subcutaneous adipose tissue. Interestingly, most of the examined tissues/organs showed a significant variation of FKBP5 gene expression after the administration of dexamethasone in combination with estradiol. So, these changes suggest that the FKBP5 gene expression could be a possible biomarker of the illegal dexamethasone administration in calves.

Abstract
The aim of this work was to study the transcriptional effects of glucocorticoids on corticosteroid hormone receptors, prereceptors (11β-hydroxysteroid dehydrogenase 1 and 2, 11β-HSD1 and 2), and chaperones molecules regulating intracellular trafficking of the receptors (FKBP51 and FKBP52) in thymus of veal calves. Moreover, the expression of FKBP51 and FKBP52 gene were investigated in beef cattle thymus. In the cervical thymus of veal calves, dexamethasone administration in combination with estradiol decreased FKBP51 expression (P < 0.01). The same treatment increased mineralocorticoid receptor (MR) (P < 0.01) and 11β-HSD1 expression (P < 0.05) compared to control group in the cervical thymus of veal calves. The thoracic thymus of veal calves treated with dexamethasone and estradiol showed a decrease of FKBP51 (P < 0.05), FKBP52 (P < 0.05), glucocorticoid receptor (P < 0.05), and MR expression (P < 0.05) compared to control group in the thoracic thymus of veal calves. The gene expression of FKBP51 decreased both in cervical (P < 0.01) and thoracic thymus (P < 0.01) of beef cattle treated with dexamethasone and estradiol. In addition, also prednisolone administration reduced FKBP51 expression in the cervical thymus (P < 0.01) and in the thoracic thymus of beef cattle (P < 0.01). The gene expression of FKBP52 increased only in the cervical thymus following dexamethasone administration (P < 0.01). The decrease of FKBP51 gene expression in thymus could be a possible biomarker of illicit dexamethasone administration in bovine husbandry. Moreover, so far, an effective biomarker of prednisolone administration is not identified. In this context, the decrease of FKBP51 gene expression in thymus of beef cattle following prednisolone administration could play an important role in the indirect identification of animals illegally treated with prednisolone.

Altern Ther Health Med 2015; 15:404. [PMID: 26553005 PMCID: PMC4640413 DOI: 10.1186/s12906-015-0927-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2014] [Accepted: 11/02/2015] [Indexed: 01/24/2023]
Abstract
Background During the past few years, there has been an increasing interest among the Traditional and Folk medical practitioners of Sri Lanka in the use of a decoction prepared from Flueggea leucopyrus (Willd.) for treating various cancers including breast cancer. In the present study, the cytotoxicity of this decoction and its effects on Heat Shock Protein (HSP) expression and apoptosis were compared in three breast cancer phenotypes, to scientifically evaluate if a decoction prepared from F. leucopyrus (Willd.) is useful for the treatment of breast cancer. Methods Cytotoxic potential of the F. leucopyrus decoction was determined by evaluating its effects in MCF-7, MDA-MB-231 and SKBR-3 breast cancer cell lines, and MCF-10A (non-cancerous) breast cell line, by use of the Sulphorhodamine (SRB) assay. The effect of the decoction on HSP gene expression in the above cells was evaluated by (a) Real time reverse transcription PCR (RT-PCR) and (b) Immunofluorescence analysis of HSP protein expression. Effects of the decoction on apoptosis were evaluated by (a) fluorescent microscopic examination of apoptosis related morphological changes and (b) DNA fragmentation (c) Caspase 3/7 assay. Results F. leucopyrus decoction can mediate significant cytotoxic effects in all three breast cancer cells phenotypes (IC50 values: 27.89, 99.43, 121.43 μg/mL at 24 h post incubation periods, for MCF-7, MDA-MB-231, SKBR-3 respectively) with little effect in the non-cancerous breast cell line MCF-10A (IC50: 570.4 μg/mL). Significant (*P <0.05) inhibitions of HSP 90 and HSP 70 expression were mediated by the decoction in MCF-7 and MDA-MB-231, with little effect in the SKBR-3 cells. Clear apoptotic morphological changes on Acridine orange/Ethidium bromide staining and DNA fragmentation were observed in all three breast cancer cell lines. Caspase 3/7 were significantly (*P <0.05) activated only in MDA-MB-231 and SKBR-3 cells indicating caspase dependent apoptosis in these cells and caspase independent apoptosis in MCF-7 cells. Conclusions Modulation of HSP 90 and HSP 70 expressions is a possible mechanism by which the decoction of F. leucopyrus mediates cytotoxic effects MCF-7 and MDA-MB-231 cells. This effect appears to correlate with enhanced apoptosis in these cells. In SKBR-3 cells, mechanisms other than HSP inhibition may be utilized to a greater extent by the decoction to mediate the observed cytotoxic effects. Overall findings suggest that the decoction has the potential to be exploited further for effective treatment of breast cancer.

Abstract
Breast cancer drug development costs nearly $610 million and 37 months in preclinical mouse model trials with minimal success rates. Despite these inefficiencies, there are still no consensus breast cancer preclinical models. Murine mammary adenocarcinoma 4T1-luc2 cells were implanted subcutaneous (SQ) or orthotopically percutaneous (OP) injection in the area of the nipple, or surgically into the chest 2nd mammary fat pad under direct vision (ODV) in Balb/c immunocompetent mice. Tumor progression was followed by in vivo bioluminescence and direct measurements, pathology and survival determined, and tumor gene expression analyzed by genome-wide microarrays. ODV produced less variable-sized tumors and was a reliable method of implantation. ODV implantation into the chest 2nd mammary pad rather than into the abdominal 4th mammary pad, the most common implantation site, better mimicked human breast cancer progression pattern, which correlated with bioluminescent tumor burden and survival. Compared to SQ, ODV produced tumors that differentially expressed genes whose interaction networks are of importance in cancer research. qPCR validation of 10 specific target genes of interest in ongoing clinical trials demonstrated significant differences in expression. ODV implantation into the chest 2nd mammary pad provides the most reliable model that mimics human breast cancer compared from subcutaneous implantation that produces tumors with different genome expression profiles of clinical significance. Increased understanding of the limitations of the different preclinical models in use will help guide new investigations and may improve the efficiency of breast cancer drug development .

Abstract
Stathmin, a steroid-responsive regulatory protein of oligodendrocyte migration and survival, is highly expressed in active brain lesions of patients with multiple sclerosis (MS) and probably involved in myelin degeneration and repair. Here, we analyzed a single nucleotide polymorphism (rs182455) within the stathmin promoter that is close to a putative steroid-responsive element and has a high minor allelic frequency, in 647 clinically well characterized MS patients and 519 healthy controls. Allelic frequencies were comparable between MS patients and healthy controls. Furthermore, disease course (relapsing-remitting versus secondary progressive versus primary progressive), age of onset or progression index did not convincingly differ between genotypes. We conclude that despite potential importance of stathmin in the pathogenesis of MS, the rs182455 polymorphism does not influence MS susceptibility or clinical disease course.
