Abstract
Proteins are the ultimate product of gene expression. As they hinge between gene transcription and phenotype, they offer a more realistic perspective of toxicopathic effects, responses and even susceptibility to insult than targeting genes and mRNAs while dodging some inter-individual variability that hinders measuring downstream endpoints like metabolites or enzyme activity. Toxicologists have long focused on proteins as biomarkers but the advent of proteomics shifted risk assessment from narrow single-endpoint analyses to whole-proteome screening, enabling deriving protein-centric adverse outcome pathways (AOPs), which are pivotal for the derivation of Systems Biology informally named Systems Toxicology. Especially if coupled pathology, the identification of molecular initiating events (MIEs) and AOPs allow predictive modeling of toxicological pathways, which now stands as the frontier for the next generation of toxicologists. Advances in mass spectrometry, bioinformatics, protein databases and top-down proteomics create new opportunities for mechanistic and effects-oriented research in all fields, from ecotoxicology to pharmacotoxicology.

Alyahya AAI, Asad M. Repeated 28-DAY oral dose study on Boswellia sacra oleo gum resin extract for testicular toxicity in rats. JOURNAL OF ETHNOPHARMACOLOGY 2020; 258:112890. [PMID: 32330512 DOI: 10.1016/j.jep.2020.112890] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/08/2019] [Revised: 04/10/2020] [Accepted: 04/14/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Frankincense (Boswellia sacra Fluck.,) is a widely used herbal drug and household medicine for treatment of several diseases. Earlier toxicological studies revealed its proulcerogenic effect and no significant hepatotoxic or nephrotoxic effects in rats. However, some other members of Boswellia species such as Boswellia papyrifera (Caill. ex Delile) Hochst and Boswellia carterii have been reported for testicular toxicity in rats. AIM OF THE STUDY Testicular toxicity of standardized methanolic extract of B. sacra oleo gum resin was determined through repeated oral dose administration for 28 days. Biochemical, histological and genetic changes in rat testes were evaluated. MATERIALS AND METHODS B. sacra extract was analyzed for its boswellic acid content by high performance liquid chromatography (HPLC) method. The extract was administered at three different doses to rats. Effect on behavior, weight, food and water consumption along with changes in serum testosterone levels and cytoarchitecture of testis, epididymis and adrenal gland were determined. Gene expression of GSTPi, IGFBP3 and HSP70 in testis was also studied. RESULTS Boswellic acids (α and β) were present in highest concentration whereas acetyl-11-keto beta boswellic acid was present in relatively smaller amounts. The extract did not produce any significant change in the behavior of the animals, food/water consumption or weight gain. Serum testosterone levels were significantly decreased only by highest tested dose of Boswellia extract (1000 mg/kg, p.o). Histological examination did not reveal any variation in the structure of testis, adrenal gland and epididymis after administration of the extract while the expression of all three studied genes was significantly decreased. CONCLUSION The results indicate that B. sacra extract does not possess any toxic effect on testis. On the contrary, decrease in gene expression of GSTPi, IGFBP3 and HSP70 revealed its antioxidant potential that may protect testes against effect of toxicants. However, a significant reduction in serum testosterone levels point to mechanisms other than direct testicular toxicity.

Abstract
Certain dietary flavonoids exhibit protective potentials against drug-induced male reproductive toxicities. We investigated the protective effects of quercetin and rutin on sulphasalazine-induced alterations in steroidogenic enzyme activity, hormone profile and spermiotoxicity in rats. Sulphasalazine (SASP, 600 mg/kg bw) was administered alone or in combination with quercetin (20 mg/kg bw) or rutin (10 mg/kg bw) for 14 days. SASP treatment significantly increased relative weights of the epididymis and seminal vesicles. Also, testicular and epididymal sperm numbers (TSN, ESN), motility, daily sperm production (DSP) and acrosome reaction (AR) significantly decreased. SASP altered plasma testosterone, luteinising hormone (LH) and follicle-stimulating hormone (FSH) levels while testicular cholesterol levels, 3β-hydroxysteroid dehydrogenase (3β-HSD) and 17β-hydroxysteroid dehydrogenase (17β-HSD) activities were decreased. Elevated malondialdehyde levels and concomitant decrease in reduced glutathione, glutathione-S-transferase, peroxidase and superoxide dismutase activities were evident in testis and epididymis of SASP-treated rats. Quercetin or rutin co-treatment with SASP significantly reversed organ weights, preserved sperm integrity, restored plasma hormone levels and increased cholesterol levels, 3β-HSD and 17β-HSD activities in testis. Both flavonoids also prevented oxidative stress in testis and epididymis of SASP-treated rats. Quercetin and rutin protect against the negative effects of SASP treatment on reproductive capacity in male rats.

Abstract
Propolis is an adhesive substance which is collected and used by honeybees. Propolis is a potent antioxidant and a free radical scavenger. This study was designed to determine whether propolis could protect against dysfunction and oxidative stress induced by methotrexate-induced injury in rat testis. A total of 40 male Wistar albino rats were divided into four groups: group 1 was the untreated control. On the eighth day of the experiment, groups 2 and 3 received single intraperitoneal injections of methotrexate (MTX) at 20mg/kg. Groups 3 and 4 received 100mg/kg/day propolis (by oral gavage) for 15 days by the first day of the experimental protocol. Then the rats were decapitated under anesthesia, and their testes were removed. The histopathological and biochemical analysis along with apoptosis assessment of testis tissues were compared. Immunohistochemical analysis of Heat shock protein-70 (HSP-70) and Proliferating Cell Nuclear Antigen (PCNA) were performed. The phenolic characterization of propolis was performed by Liquid chromatography-mass spectrometry (LC-MS/MS). Methotrexate caused tended to increase in malondialdehyde level and in the number of apoptotic cells; it also caused a decrease in MSTD and JTBS, PCNA and HSP-70 expression and xanthine oxidase levels in group 2. Propolis prevented the rise in malondialdehyde, xanthine oxidase levels and HSP-70 expression and improved testicular morphology and JTBS. It was found that, methorexate gives rise to serious damage in the testes and propolis is a potent antioxidant agent in preventing testicular injury.

Abstract
1,3-Dinitrobenzene (DNB) is an industrial intermediate and testicular toxicant that has been shown to target Sertoli cells. The mechanism of action of DNB in the testis, however, is unclear. To investigate global alterations in gene or protein expression during testicular toxicity, testes from rats treated orally with DNB were subjected to microarray and two-dimensional gel electrophoresis (2-DE) analyses. Histopathological abnormalities were detected in the testes of the DNB-treated rats. Microarray analysis revealed that, during early testicular toxicity, several genes involved in apoptosis, germ cell/Sertoli cell junction, and tight junction signaling pathways were differentially expressed. Based on 2-DE analysis, 36 protein spots showing significantly different expression during early testicular toxicity were selected and identified. Network analysis of the identified proteins revealed that these proteins are associated with cellular development or reproductive system diseases. Collectively, these data will help clarify the molecular mechanism underlying testicular toxicity in DNB-exposed rats.

Abstract
Aim of the current study was to investigate the ability of deltamethrin to induce testicular injury in rats and its possible attenuation with lycopene. Rats were divided into three groups: Group I (DEL) received deltamethrin, 5 mg/kg b.w./day orally, in corn oil. Group II (DEL + Lyc) received oral dose of lycopene (4 mg/kg b.w./day) in corn oil concurrently with deltamethrin following the same regimen as in group I. Group III (Control) received appropriate volume of corn oil. After 4 weeks, deltamethrin-treated rats showed decreased body weight, serum testosterone, luteinizing hormone and follicle-stimulating hormone levels. Testicular total oxidant capacity (TOC), nitrite/nitrate (NOx), poly (ADP-ribose) polymerase (PARP), and DNA damage were significantly increased. RT-PCR demonstrated significant up-regulation in testicular mRNA for glutathione-S-transferase and heat-shock protein-70 (HSP-70), whereas steroidogenic acute regulatory (StAR) protein was down-regulated after deltamethrin exposure. Lycopene was able to restore body weight, serum testosterone, StAR mRNA, TOC, NOx levels, and PARP activity with significant decrease in HSP-70 mRNA, and DNA damage. In conclusion, lycopene was able to counteract the deleterious effect of deltamethrin.

Abstract
Proteomics, an interface of rapidly evolving advances in physics and biology, is rapidly developing and expanding its potential applications to molecular and cellular biology. Application of proteomics tools has contributed towards identification of relevant protein biomarkers that can potentially change the strategies for early diagnosis and treatment of several diseases. The emergence of powerful mass spectrometry-based proteomics technique has added a new dimension to the field of medical research in liver, heart diseases and certain forms of cancer. Most proteomics tools are also being used to study physiological and pathological events related to reproductive biology. There have been attempts to generate the proteomes of testes, sperm, seminal fluid, epididymis, oocyte, and endometrium from reproductive disease patients. Here, we have reviewed proteomics based investigations in humans over the last decade, which focus on delineating the mechanism underlying various reproductive events such as spermatogenesis, oogenesis, endometriosis, polycystic ovary syndrome, embryo development. The challenge is to harness new technologies like 2-DE, DIGE, MALDI-MS, SELDI-MS, MUDPIT, LC-MS etc., to a greater extent to develop widely applicable clinical tools in understanding molecular aspects of reproduction both in health and disease.

Abstract
A comparative study of proteome maps from control and Cd-exposed rat liver was performed using a new technology of two-dimensional liquid chromatography separation method (PF-2D system, Beckman Coulter). Rats were fed for one month 0 or 100 μg Cd g(-1). The between-replicate and between-sample variations showed good repeatability and suitable reproducibility for the two dimensions of separation of proteins. In this complex mixture, PF-2D led to the separation of two major peaks which differed between control and Cd-exposed rat livers, one being identified by mass spectrometry as Cu/Zn superoxide dismutase (SOD), a well-known biomarker of Cd exposure, the other as phosphatidylethanolamine binding protein (PEBP). SOD content was decreased in Cd-exposed rat liver, compared to the control group which was corroborated by a significant decrease of SOD activity. PEBP content also tended to be decreased after Cd exposure. Present results demonstrate interest but also limitations of proteomic approach using PF-2D system to analyze effects of chemicals on organisms.

Abstract
Two-dimensional gel electrophoresis (2DGE) continues to be a useful approach to study protein expression. Although liquid chromatographic and mass spectrometric approaches that overcome some of the limitations and labour intensity of 2DGE are increasingly popular, this electrophoretic approach still has exceptional relevance in toxicology. Despite the technical challenges, pharmacologists/toxicologists continue to use gel-based proteomics to assess the biological and health effects of chemical treatment and exposure. This brief review addresses the use of 2DGE-based proteomics in drug development and toxicology, emphasising its unique strengths and weaknesses, and considers recent developments in this strategy that have evolved to directly confront the issues of dynamic range and reproducibility that have previously limited the overall use of 2D electrophoresis.

Abstract
Aims of this chapter on the role of toxicoproteomics in assessing organ-specific toxicity are to define the field of toxicoproteomics, describe its development among global technologies, and show potential uses in experimental toxicological research, preclinical testing and mechanistic biological research. Disciplines within proteomics deployed in preclinical research are described as Tier I analysis, involving global protein mapping and protein profiling for differential expression, and Tier II proteomic analysis, including global methods for description of function, structure, interactions and post-translational modification of proteins. Proteomic platforms used in toxicoproteomics research are briefly reviewed. Preclinical toxicoproteomic studies with model liver and kidney toxicants are critically assessed for their contributions toward understanding pathophysiology and in biomarker discovery. Toxicoproteomics research conducted in other organs and tissues are briefly discussed as well. The final section suggests several key developments involving new approaches and research focus areas for the field of toxicoproteomics as a new tool for toxicological pathology.

Abstract
The aliphatic ether 1,6-dimethoxyhexane (DMH) was previously identified as a testicular toxicant. Testis protein extracts from control and DMH-treated rats were subjected to two-dimensional gel electrophoresis for comparison of protein expression profiles. MALDI-ToF peptide mass fingerprinting of differentially expressed proteins resulted in the conclusive identification of heat shock-related 70kDa protein 2 (HSP70.2), 60kDa heat shock protein, mitochondrial precursor (HSP60) and protein disulfide isomerase A3 precursor (ERp60). The potential involvement of these proteins in chemically induced perturbation of spermatogenesis and their utility as biomarkers of testicular toxicity are discussed in light of the knowledge currently available from the literature.

Abstract
Development of toxicological and clinical biomarkers for disease diagnosis, quantification of toxicant/drug responses and rapid patient care are major concerns in modern biology. Even after human genome sequencing, identification of specific molecular signatures for unambiguous correlation with toxicity and clinical interventions is a challenging task. Differential protein expression patterns and protein-protein interaction studies have started unraveling rigorous molecular explanation of multi-factorial and toxicant borne diseases. Proteome profiling is extensively used to investigate etiology of diseases, develop predictive biomarkers for toxicity and therapeutic interventions and potential strategies for treatment of complex and toxicant mediated diseases. In this review, achievements and limitations of proteomics in developing predictive biomarkers for toxicological and clinical interventions have been discussed.
