AIMS Keratinocyte apoptosis is a major pathogenic mechanism in dermal complications, such as graft versus host disease (GVHD), after allogeneic bone marrow transplantation. However, the mechanisms by which recipient target cells undergo apoptosis in GVHD are still unclear, but may result from DNA damage caused by chemotherapeutic agents and/or by direct cytokine action. The basis of this invest...

objective(s):in previous investigations, we have shown para-nonylphenol (p-np) caused significant reduction of proliferation and differentiation of rat bone marrow mesenchymal stem cells (mscs) in vitro. in this study, we first treat the rats with p-np, then carried out the biochemical and morphological studies on mscs. materials and methods: proliferation property of cells was evaluated with t...

Background: Alzheimer disease is the main cause of dementia in middle-aged and elderly people. Considering the improving effects of creatine supplementation on cognitive performance, this study aimed to determine the effects of creatine supplementation on learning, memory, and apoptosis in an experimental model of Alzheimer’s disease. Methods: Thirty-two male Wistar rats each weighing 250±50...

Objective: Liver cancer is one of the most common causes death, with reduced survival rates. The development new chemotherapeutic agents essential to find effective cytotoxic drugs that give minimum side effects surrounding healthy tissues. main objective present study was evaluate and mechanism cell death induced by crude diethyl ether extract Xylocarpus mouccensis on human hepatocellular carc...

Neonatal isolation (NI) has detrimental consequences on the hippocampal neurons of rat neonates. It been reported to enhance neuronal cell death and impair memory behaviors. We conducted this study assess effects NI apoptosis recognition impairment in hippocampus One group male Wistar neonates exposed NI; reared with 1-hour neonatal for eight consecutive days (P2-P9). On other hand, control nor...

Spinal cord injury (SCI) is the major cause of severe disability worldwide, which leads to neuron death, neuronal degeneration, and functional changes in spinal cord. Eucommia ulmoides extract (EUE) composed multiple iridoids phenols possesses anti-oxidative anti-inflammatory effects various pathologies. This study aims evaluate EUE on SCI underlying mechanisms. Male adult Sprague-Dawley rats (...

Myocardial ischemia-reperfusion (MI/R) injury is a common and serious complication following reperfusion treatment for myocardial infarction (MI). Increasing evidence has verified the crucial role of circular RNAs (circRNAs) in MI/R processes. The objective this study was to investigate effects potential regulatory mechanisms circHMGA2 on injury. Hypoxia/reoxygenation (H/R) models were establis...

background and aims. there is no report on the apoptotic impact of allium sativum l. (garlic) on the oral squamous cell carcinoma (kb); hence, this study was designed to survey the apoptotic effects of garlic fresh juice (gfj) on the kb cells. materials and methods. mtt assay (microculture tetrazolium assay) was carried out to evaluate the cytotoxicity of gfj on kb cells. furthermore, tunel (te...

background and objective: garlic has been known worldwide as a dietary constituent with many pharmacological effects. the present in vitro study was designed to investigate the putative anticancer effect of garlic extract on cancer cells, and if this effect was through apoptosis induction. material and methods:  human colon adenocarcinoma cells ht29 were treated with different doses (1, 5 and 1...

PURPOSE The effects of leukotriene (LT) B4 and its receptor antagonist LY293111 on proliferation and apoptosis of human pancreatic cancer cells were investigated, both in vitro and in vivo. EXPERIMENTAL DESIGN Six human pancreatic cancer cell lines (MiaPaCa-2, HPAC, Capan-1, Capan-2, PANC-1, and AsPC-1) were used. Expression of LTB4 receptors, BLT1 and BLT2, was measured by reverse transcript...
