Nowadays, major attention is being paid to curing different types of cancers and is focused on natural resources, including oceans and marine environments. Jellyfish are marine animals with the ability to utilize their venom in order to both feed and defend. Prior studies have displayed the anticancer capabilities of various jellyfish. Hence, we examined the anticancer features of the venom of Cassiopea andromeda and Catostylus mosaicus in an in vitro situation against the human pulmonary adenocarcinoma (A549) cancer cell line. The MTT assay demonstrated that both mentioned venoms have anti-tumoral ability in a dose-dependent manner. Western blot analysis proved that both venoms can increase some pro-apoptotic factors and reduce some anti-apoptotic molecules that lead to the inducing of apoptosis in A549 cells. GC/MS analysis demonstrated some compounds with biological effects, including anti-inflammatory, antioxidant and anti-cancer activities. Molecular docking and molecular dynamic showed the best position of each biologically active component on the different death receptors, which are involved in the process of apoptosis in A549 cells. Ultimately, this study has proven that both venoms of C. andromeda and C. mosaicus have the capability to suppress A549 cells in an in vitro condition and they might be utilized in order to design and develop brand new anticancer agents in the near future.
Lung cancer is one of the most lethal malignancies in the world. However, current curative approaches for treating this type of cancer have some weaknesses. Therefore, scientists are attempting to discover new anti-lung cancer agents. Sea cucumber is a marine-derived source for discovering biologically active compounds with anti-lung cancer properties. To explore the anti-lung cancer properties of sea cucumber, we analyzed surveys using VOSviewer software and identified the most frequently used keywords. We then searched the Google Scholar database for compounds with anti-lung cancer properties within that keyword family. Finally, we used AutoDock 4 to identify the compounds with the highest affinity for apoptotic receptors in lung cancer cells. The results showed that triterpene glucosides were the most frequently identified compounds in studies examining the anti-cancer properties of sea cucumbers. Intercedenside C, Scabraside A, and Scabraside B were the three triterpene glycosides with the highest affinity for apoptotic receptors in lung cancer cells. To the best of our knowledge, this is the first time that anti-lung cancer properties of sea cucumber-derived compounds have been examined in in silico conditions. Ultimately, these three components displayed anti-lung cancer properties in in silico conditions and may be used for the manufacture of anti-lung cancer agents in the near future.
Diabetes mellitus is one of the most common diseases of the body's endocrine system; and despite great progresses in its controlling in pregnant women the risk of birth of abnormal babies in these patients is significantly higher than healthy people. Now, the original and effective treatment of diabetes is consumption of insulin and glucose-lowering chemical medicines. But, these compounds have numerous side effects. According to this, consumption of medicinal plants in order to reduce the complications of the disease during pregnancy period is recommended. So this study is aimed to investigate possible morphological changes resulting from administration of the extraction of Panax ginseng root on ovarian tissue changes of three-month-old-rats born to diabetic mothers. A number of 32 adult female Sprague-Dawley rats approximately weighing 200-250 g were prepared and divided into four groups of eight each that included: healthy control group (the rats were kept without receiving any material), diabetic control group (the rats received 50 mg/kg Streptozotocin as intraperitoneally), ginseng control group (the rats received 400 mg/kg oral dose of Panax ginseng extract) and ginseng treatment group (the rats received 50 mg/kg dose of Streptozotocin as intraperitoneally and 400 mg/ kg oral dose of Panax ginseng extract). After becoming pregnant and passing from this period, a number of five three-month-old female rat infants were selected from each group. The animals were then dissected and their ovarian tissues were removed for tissue studies and H-E staining. Number of primordial follicles in diabetic control group had significant reduction compared to healthy control group. Also the number of primordial follicles in ginseng control group had significant increase compared to diabetic control group. Diameter of primordial, primary, secondary and graafian follicles and corpus luteum had significant decrease compared to the healthy control group. Also the size of primordial, primary, secondary and graafian follicles and corpus luteum had significant increase in ginseng control group compared to diabetic control group. The size of primordial follicle in ginseng treatment group had significant increase compared to diabetic control group (p<0.05). Given the above, it is found that the number and the size of ovarian follicles in three-month-old infants born to diabetic mother rats had reduced due to production of free radicals as well as induction of apoptosis; and Panax ginseng extract, due to its antioxidant compounds and also its apoptogenic properties, had improved changes of ovarian tissue in infants born to diabetic mother rats.
More research is being conducted on myocardial cell treatments utilizing stem cell lines that can develop into cardiomyocytes. All of the forms of cardiac illnesses have shown to be quite amenable to treatments using embryonic (ESCs) and induced pluripotent stem cells (iPSCs). In the present study, we reviewed the differentiation of these cell types into cardiomyocytes from an epigenetic standpoint. We also provided a miRNA network that is devoted to the epigenetic commitment of stem cells toward cardiomyocyte cells and related diseases, such as congenital heart defects, comprehensively. Histone acetylation, methylation, DNA alterations, N6-methyladenosine (m6a) RNA methylation, and cardiac mitochondrial mutations are explored as potential tools for precise stem cell differentiation.
Background & Objective: This study was designed to evaluate the effect of sleeve-gastrectomy procedure on weight loss, glucose and insulin blood levels in overweight dogs. Materials & Methods: In the current study, 5 overweight dogs (31.6±3.03kg) were selected for sleeve-gastrectomy procedure. Insulin and glucose levels were measured from the blood samples that were taken before the surgery and weekly 1.5 month post-operatively. The weight of the dogs was also measured at the same time. The surgery was performed according to the technique described by Gagner 2009, and the dogs received special diet during the recovery period to end of the study. Results: One dog died due to dehiscence and leakage 48 hours post-operatively. Decrease in mean weight was 6.25±0.44 in the first week after surgery and the weight loss process continued to end of the study. Changes in insulin and glucose blood levels demonstrated to have pulsatile patterns. Insulin levels decreased for the first week, but its level increased in the second week period. Again, insulin levels demonstrated to have decreasing pattern in the following 4 weeks. On the other hand, the glucose levels changed each week and did not show any certain pattern. Conclusion: Post-operative weight loss was observed in all cases but it was not statistically significant. It could be due to limited number of the samples. The glucose and insulin changes were attributed to hormonal changes particularly gut hormones that were affected by sleeve-gastrectomy procedure but further detailed studies on hormonal effect are required.
Endometriosis is an enigmatic gynecological disease initiated by the ectopic growth of endometrial tissue and causes critical symptoms such as chronic pelvic pain, cyclic menstrual pain, subfertility or infertility. Considering extensive investigations for explaining the underlying pathophysiology of endometriosis, origin and distinctive processes which lead to endometritic state are not completely understood. In this comprehensive review, studies published from 2010 to 2021 are reviewed in order to provide a bright insight through the applications of translational animal models and endometriosis induction methods for evaluation of endometriosis pathogenesis and treatment. We provided method based inclusion criteria and reviewed all hormone-based studies with concentration on animal models. Additionally, studies with novel induction methods and approaches are categorized separately and analyzed by a novel scoring table for suitability of further investigations. Eventually, our scoring system suggested that the best-evaluated animal model for hormone related endometriosis studies is an “unopposed estrogenicity baboon model of endometriosis”.
Ischemia-reperfusion injury (IRI) is a complex pathophysiological process that can lead to severe and irreversible consequences, including the complete loss of renal function. While standardized strategies for preventing IRI during "back-table" and cold preservation are available, various intraoperative prevention methods have been proposed to mitigate the harmful effects of warm ischemia and reperfusion of the kidney. These methods include pharmacological agents, mechanical interventions, and surgical techniques such as renal capsulotomy, ischemic preconditioning, venous blood reperfusion, renal perfusion, and the use of tissue engineering techniques like mesenchymal stromal/stem cells and/or decellularization. In this comprehensive analysis, we provide a detailed overview of pharmacological agents and intraoperative methods and approaches for the prevention and treatment of renal IRI. We begin by discussing the mechanisms of IRI and the challenges of preventing it during surgery. Then using a bibliometric analysis and molecular docking of brand-new legends we showed eplerenone have the most binding affinity to Aldehyde dehydrogenase (AD), Estrogen receptor (ER), Klotho protein, Mineralocorticoid receptor (MR), and Toll-like receptor 4 (TLR4) for preventing IRI comparing with other available therapeutics, Benzodioxole, Hydrocortisone, Indoles, Nicotinamide adenine dinucleotide, and Niacinamide. Next, we provide a comprehensive analysis of the potential benefits and limitations of various prevention strategies, including an in-depth discussion of the mechanisms of action of pharmacological agents, mechanical interventions, and surgical techniques. Furthermore, we introduce a novel scoring system for the prevention methods of kidney IRI, which takes into account the effectiveness, feasibility, and safety of each method. We then analyze the current state of clinical research in this area and discuss the implications of these methods for future clinical practice. Overall, this article provides a valuable resource for clinicians and researchers seeking to prevent and treat renal IRI in surgical settings, and introduces a new scoring system that can be used to guide the selection of the most effective and safe prevention methods.
