background: oligodendrocytes, the myelinating glial cells of central nervous system, are highly vulnerable to ischemic‑induced excitotoxic insult, a phenomenon in which calcium overload triggers cell death. berberine is an alkaloid extracted from medicinal herbs as coptidis rhizoma with several pharmacological effects like inhibition of neuronal apoptosis in cerebral ischemia. methods: we exami...

mono-targeting by imatinib as a main antitumor agent does not always accomplish complete cancer suppression. 2,5-dimethyl-celecoxib (dmc) is a close structural analog of the selective cyclooxygenase-2 (cox-2) inhibitor, celecoxib, that lacks cox-2 inhibitory function. in this study, we aimed to show the apoptotic effects of imatinib in combination with dmc in human ht-29 colorectal cancer (crc)...

background: radiation-induced bystander effect is a response which results in damage in non-irradiated cells in response to signals from the irradiated cells. the aim of the present study was to investigate microwave-induced bystander effect from a gsm mobile phone simulator on induction of apoptosis in jurkat cell line. materials and methods: jurkat cells were divided into three groups of non-...

introduction: oxidative stress and neuroinflammation are involved in neurodegeneration procedure in parkinson’s disease. recently, neuroprotective potential of boswellia resin has been demonstrated. therefore, this study examined whether administration of boswellia resin would attenuate mpp+- induced neuronal death in sk-n-sh- cell line, a human dopaminergic neurons- in vitro. methods: boswelli...

ATM, ATR and DNA-PK are critical for DNA damage response (DDR) and sequential repair, leading to genomic stability. In this study, we found the expression of these proteins is markedly induced by PMA during THP1 differentiation without the change in the level of transcripts. Also, inhibitors of these protein activity suppressed PMA-induced morphological change of THP1 cells. Our results suggest...

Ehrlichia chaffeensis is an obligatory intracellular bacterium which resides in an early endosome in monocytes. E. chaffeensis infection in a human monocyte cell line (THP1) significantly altered the transcriptional levels of 4.5% of host genes, including those coding for apoptosis inhibitors, proteins regulating cell differentiation, signal transduction, proinflammatory cytokines, biosynthetic...

nano-silver (agnp) has biological properties which are significant for consumer products, food technology, textiles and medical applications (e.g. wound care products, implantable medical devices, in diagnosis, drug delivery, and imaging). for their antibacterial activity, silver nanoparticles are largely used in various commercially available products. thus, the use of nano-silver is becoming ...

Abstract Background The poor prognosis of advanced HCC and limited efficacy current systemic treatments emphasize the need for new or combined targeted therapies. development is a multistage process in which liver injury appears complex microenvironment associated with oxidative stress. NOX enzymes are main source ROS during hepatocarcinogenesis NOX1 particular has shown correlation patients. T...

objective(s): glioblastoma is the most lethal tumor of the central nervous system. here, we aimed to evaluate the effects of exogenous delivery of p53 and a nanoformulation of curcumin called dendrosomal curcumin (dnc), alone and in combination, on glioblastoma tumor cells. materials and methods: mtt assay was exploited to measure the viability of u87-mg cells against dnc treatment. cells were ...
