Turkish Journal of Medical Sciences

Background/aim: Thermopsis turcica is a perennial species endemic to Turkey and different extracts of T. turcica have an antiproliferative effect on cancer cells, but there has not been any report on HeLa (human cervical cancer) cells. Materials and methods: To get a better understanding of the molecular mechanism of anticancer activity of methanolic extracts of leaves (LE) and flowers (FE) of T. turcica, we employed 2-DE-based proteomics to explore the proteins involved in anticancer activity in HeLa cells. Results: T. turcica extracts showed a potent cytotoxic effect on HeLa cells with the IC50 values of 1.75 mg/mL for LE and …


The Potential Of Salvia Officinalis As A Suppressor Of Cell Proliferation In Animal Feed And Human Nutrition: An Experimental Stud, Muhammet Kuddusi̇ Erhan Jan 2020

The Potential Of Salvia Officinalis As A Suppressor Of Cell Proliferation In Animal Feed And Human Nutrition: An Experimental Stud, Muhammet Kuddusi̇ Erhan

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to examine the in vitro cytotoxic activities of Salvia officinalis (sage) oil on human immortalized keratinocyte (HaCaT) cell lines by using an [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide] (MTT) cytotoxicity assay after the Salvia officinalis oil administration in different doses and time-points. In vitro cytotoxic activities of Salvia officinalis oil on HaCaT cell lines were assessed, and MTT assays were used to determine cell viability. The HaCaT cells (100 µL) were cultured in 96well plates at 2 × 104 cells per well and treated with different concentrations of Salvia officinalis oil (25 µM, 50 µM, 100 µM, 150 µM, …


The Anti Proliferative Effects Of Rosemary Oil On Keratinocyte Cell Line, Hacat, Muhammet Kuddusi̇ Erhan Jan 2020

The Anti Proliferative Effects Of Rosemary Oil On Keratinocyte Cell Line, Hacat, Muhammet Kuddusi̇ Erhan

Turkish Journal of Veterinary & Animal Sciences

This study aims to investigate the action of rosemary oil on the immortalized keratinocyte cell line. Samples of Rosmarinus officinalis that were growing uncultivated in central Turkey were harvested during flowering in May 2016. The rosemary oil was obtained by the hydrodistillation of the dried ground material in a Clevenger-like apparatus. Human cells from the immortalized nontumorigenic keratinocyte cell line were seeded at a concentration of 5000 cells/well on 96 well plates. Cell viability was measured at the 24, 48, and 72 h. Five different doses of 1.25% to 20% Rosmarinus officinalis oil, 20% DMSO (for toxic examination), and 1 …


Physiological And Pharmacological Roles Of Melatonin In The Pathophysiologicalcomponents Of Cellular Injury After Ischemic Stroke, Ertuğrul Kiliç, Berrak Çağlayan, Mustafa Caglar Beker Jan 2020

Physiological And Pharmacological Roles Of Melatonin In The Pathophysiologicalcomponents Of Cellular Injury After Ischemic Stroke, Ertuğrul Kiliç, Berrak Çağlayan, Mustafa Caglar Beker

Turkish Journal of Medical Sciences

Apart from its metabolic or physiological functions, melatonin has a potent cytoprotective activity in the physiological and pathological conditions. It is synthetized by the pineal gland and released into the blood circulation but particularly cerebrospinal fluid in a circadian manner. It can also easily diffuse through cellular membranes due its small size and lipophilic structure. Its cytoprotective activity has been linked to its potent free radical scavenger activity with the desirable characteristics of a clinically- reliable antioxidant. Melatonin detoxifies oxygen and nitrogen-based free radicals and oxidizing agents, including the highly toxic hydroxyl-and peroxynitrite radicals, initiating cellular damage. However, the cytoprotective …


Evaluation Of Cytotoxic, Apoptotic Effects And Phenolic Compounds Of Sea Cucumberholothuria Tubulosa (Gmelin, 1791) Extracts, Mehli̇ka Alper, Melek Güneş Jan 2020

Evaluation Of Cytotoxic, Apoptotic Effects And Phenolic Compounds Of Sea Cucumberholothuria Tubulosa (Gmelin, 1791) Extracts, Mehli̇ka Alper, Melek Güneş

Turkish Journal of Veterinary & Animal Sciences

This study aimed to investigate the potential cytotoxic effects and phenolic contents of aqueous (HTS) and methanolic (HTM) extracts of Holothuria tubulosa gathered from Muğla (Turkey) against different cancer cells for the first time. An MTT assay was carried out to determine cellular viability. Apoptotic cell death was determined using flow cytometry. DNA fragmentation assay and caspase-3 activity analysis were carried out. Both extracts were analyzed by high performance liquid chromatography (HPLC) for quantification of phenolic compounds. Both HTS and HTM extracts generally caused a decrease in the cell viability in a concentration- and timedependent manner. The lowest IC$_{50}$ value …


Protective Effects Of Apocynin On Damaged Testes Of Rats Exposed To Methotrexate, Kübra Kavram Sarihan, Melda Yardimoğlu Yilmaz, Fatma Ceyla Eraldemi̇r, Yusufhan Yazir, Esra Acar Jan 2020

Protective Effects Of Apocynin On Damaged Testes Of Rats Exposed To Methotrexate, Kübra Kavram Sarihan, Melda Yardimoğlu Yilmaz, Fatma Ceyla Eraldemi̇r, Yusufhan Yazir, Esra Acar

Turkish Journal of Medical Sciences

Background/aim: Methotrexate (MTX), widely used as a drug in cancer, has many adverse effects on tissues. Apocynin (APO) is a NADPH oxidase inhibitor and is known with many antioxidant properties. In this study, we aimed to evaluate the adverse effects of MTX on testicular tissue and the protective effects of APO at two different doses (20 mg/kg and 50 mg/kg) on MTX-induced testicular damage.Materials and methods: Fifty adult male Wistar albino rats (8 weeks old and weighing 200-250 g) were divided into five groups of 10 rats each: 1. saline control, 2. dimethyl sulfoxide (DMSO) control, 3. MTX, 4. APO-20 …

Melatonin, Aging, And Covid-19: Could Melatonin Be Beneficial For Covid-19 Treatment In The Elderly?, Güler Öztürk, Kazi̇me Gonca Akbulut, Şevi̇n Güney Jan 2020

Melatonin, Aging, And Covid-19: Could Melatonin Be Beneficial For Covid-19 Treatment In The Elderly?, Güler Öztürk, Kazi̇me Gonca Akbulut, Şevi̇n Güney

Turkish Journal of Medical Sciences

The aim of this review is to summarize current studies on the relationship between melatonin and aging. Nowadays, age-related diseases come into prominence, and identifying age-related changes and developing proper therapeutic approaches are counted as some of the major issues regarding community health. Melatonin is the main hormone of the pineal gland. Melatonin is known to influence many biological processes in the body, including circadian rhythms, the immune system, and neuroendocrine and cardiovascular functions. Melatonin rhythms also reflect the biological process of aging. Aging is an extremely complex and multifactorial process. Melatonin levels decline considerably with aging and its decline …
