آپوپتوز (مرگ برنامه ریزی شده سلول) یک مولفه حیاتی در فرآیند های مختلفی همچون تغییرات طبیعی سلول، تکوین صحیح و کارکرد سیستم ایمنی، آتروفی وابسته به هورمون، تکوین جنینی و مرگ سلولی القاء شده با مواد شیمیایی می باشد و از طریق دو مسیر داخلی و خارجی آغاز می گردد. در مسیر داخلی محرک های مختلفی باعث رهایی سیتوکروم c از میتوکندری می شود. سپس سیتوکروم c به apaf-1 متصل و آن را به همراه پروکاسپاز9 فعال می...
multiple sclerosis is an autoimmune disease of the central nervous system which its main characteristic is an inflammation and demyelination and subsequent, neural degeneration. many studies have shown that inflammation causing neuronal demyelination. ms is the most common cause of chronic neurological disability in during youth which the prognosis is that can be death. platelet activating fact...
Background and purpose: Minocycline is an antibiotic which has anti-inflammatory and anti-seizure properties. There is no reliable evidence on the effect of Minocycline on histological structures of cerebellar Purkinje neurons. This study aimed at elucidating this effect in epileptic rats. Materials and methods: This experimental study was conducted in 24 rats which were randomly divided into ...
The anti-CD20 monoclonal antibody rituximab (Rituxan, IDEC-C2B8) has shown promising results in the clinical treatment of a subset of patients with low grade or follicular non-Hodgkin's lymphoma (NHL). However, chemotherapy- and rituximab-refractory NHL patients may benefit from a regimen in which rituximab acts as a sensitizing agent. This study examined the apoptotic signaling mediated by rit...
Background Rho-kinase signal pathway is a new target for cancer therapy. Fasudil, a selective Rho-kinase inhibitor, is found to exert antitumor effects on several types of cancer, but whether fasudil has antitumor effects on laryngeal carcinoma is still unknown. The aim of this study was to determine the effects of fasudil on laryngeal carcinoma and explore the underlying molecular mechanisms i...
Generation of reactive oxygen species (ROS) and activation of caspase cascade are both indispensable in Fas-mediated apoptotic signaling. Although ROS was presumed to affect the activity of the caspase cascade on the basis of findings that antioxidants inhibited the activation of caspases and that the stimulation of ROS by itself activated caspases, the mechanism by which these cellular events ...
Apoptosis is induced by different stimuli, among them triggering of the death receptor CD95, staurosporine, and chemotherapeutic drugs. In all cases, apoptosis is mediated by caspases, although it is unclear how these diverse apoptotic stimuli cause protease activation. Two regulatory pathways have been recently identified, but it remains unknown whether they are functionally independent or lin...
Apaf-1 is a mammalian homolog of CED-4 that regulates cell death by participating in a ternary complex with cytochrome c, and procaspase-9. In the case of CED-4, two splice variants exist. The smaller (CED-4S) is proapoptotic while the larger (CED-4L) contains a short in-frame insert and is anti-apoptotic. We cloned a murine variant of apaf-1, termed apaf-1L, which contains an eleven amino acid...
