Alternatif tıpta kemoterapi benzeri tedavi yöntemlerine ek olarak sıklıkla bitkisel kökenli doğal ilaçlar kullanılmaktadır. Panax ginseng bunlardan biridir ve sinir sistemi kaynaklı hastalıklarda tercih edilmektedir. Çalışmamızda amaç, sisplatinden önce kullanılan ginsengin YKG1 glioblastoma hücrelerinde hücre ölümü canlılığı bakımından değerlendirilmesidir. Ticari satın alınan hücreleri, % 5 C...

Back ground: Although the cell differentiation is an inseparable part of development in multicellular organisms, the regulating molecular pathway of it still is not fully defined. In the other hand, apoptosis is a fundamental physiological process which plays an essential role in a variety of biological events during development. Moreover, recent studies have found that apoptosis shows several ...

Excessive use of Ketamine (KET) has a neurotoxic effect on the brain. This study explored Transient Receptor Potential Vanilloid 4 (TRPV4) KET-induced neurotoxicity in hippocampus. We extracted and identified rat hippocampal neuronal cells. The neurons were treated with different concentrations (0, 0.1, 1, 10, 100, 300 1000 μmol/L) KET (6, 12 24 hr). Cell viability was detected by cell counting...

Treatment of human neuroblastoma SH-SY5Y cells with 1 mM 1-methyl-4-phenylpyridinium (MPP+) for 3 days induced production of reactive oxygen species (ROS), followed by caspase-3 activation, cleavage of poly(ADP-ribose) polymerase (PARP), and apoptotic cell death with DNA fragmentation and characteristic morphological changes (condensed chromatin and fragmented nuclei). Simultaneous treatment wi...

Selenium, an essential trace element, showed the significant protective effects against liver and kidney damage induced by some heavy metals. However, the mechanism how selenium suppresses cadmium (Cd)-induced cytotoxicity remains unclear. In this study, we investigated the protective mechanism of selenium on Cd-induced apoptosis in LLC-PK(1) cells via reactive oxygen species (ROS) and mitochon...

Alzheimer's disease (AD) is a fatal neurodegenerative disease. Brain amyloid-β deposition is a crucial feature of AD, causing neuronal cell death by inducing oxidative damage. Reactive oxygen species (ROS) activate NF-κB, which induces expression of Nucling. Nucling is a pro-apoptotic factor recruiting the apoptosome complex. Lycopene is an antioxidant protecting from oxidative stress-induced c...

Lycorine, a main phenanthridine Amaryllidaceae alkaloid, has shown wide ranging pharmacological activities. This study aimed to investigate the antitumor activity of lycorine against pancreatic cancer and to elucidate the underlying mechanisms. Human pancreatic cancer cell line PANC-1 was treated with lycorine. Cell viability was monitored by MTT assay. The expression of related proteins was id...

Radiation exerts direct as well as indirect effects on DNA through the generation of reactive oxygen species (ROS). Irradiated hematopoietic progenitor cells (HPCs) experience DNA strand breaks, favoring genetic instability, due to ROS generation. Our aim was to study the effect of a range of radiation doses in HPCs and the possible protective mechanisms activated by insulin-like growth factor-...
