چکیده به منظور بررسی فعالیت آنتیاکسیدانی در ارقام گلابی درگزی و ویلیام دوشس بعد از مایهزنی با باکتری مولد بیماری آتشک (E. amylovora)، آزمایشی به صورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی در سه تکرار انجام شد. ارزیابی مقاومت بر اساس درصد نسبت پیشرفت بیماری آتشک در شاخه به کل طول شاخه صورت گرفت. برخی از شاخصهای فیزیولوژیکی و بیوشیمیایی شامل آنزیمهای آسکوربات پراکسیداز (APX)، کاتالاز (CA...
Avian pox is a viral disease with a wide host range. In Great Britain, avian pox in birds of the Paridae family was first diagnosed in a great tit (Parus major) from south-east England in 2006. An increasing number of avian pox incidents in Paridae have been reported each year since, indicative of an emergent infection. Here, we utilise a database of opportunistic reports of garden bird mortali...
Proline degradation by proline dehydrogenase/proline oxidase (PRODH/POX) contributes to apoptosis or autophagy. The identification of specific pathway of apoptosis/survival regulation is the aim of this study. We generated knocked-down PRODH/POX MCF-7 breast cancer cells (MCF-7shPRODH/POX). PRODH/POX silencing did not affect cell viability. However, it contributed to decrease in DNA and collage...
هدف این مطالعه ارزیابی اثر تنش شوری بر فعالیت ایزوزیم‌های آنتی‌اکسیدان سوپراکسید‌دیسموتاز (SOD)، کاتالاز (CAT) و پراکسیداز (POX) در 18 ژنوتیپ لوبیا سفید (Phaseolusvulgaris L.) و مقایسه با شرایط طبیعی در قالب فاکتوریل با طرح پایۀ کاملاً تصادفی است. برای هر نوار ژل فعالیت ایزوزیمی با نرم‌افزار MCID به‌صورت میزان ”مساحت × شدت“ محاسبه شد. سه ایزوزیم برای SOD، یک ایزوزیم برای CAT و سه ایزوزیم برای PO...
Proline is a readily released stress substrate that can bemetabolized by proline oxidase (POX) to generate either reactive oxygen species (ROS) to induce apoptosis or autophagy or ATP during times of nutrient stress. However, the contribution of prolinemetabolism to tumorigenesis in hypoxicmicroenvironments has not been explored. In this study, we investigated the different functions of POX und...
Epidemiological studies showed that high levels of oxidized low-density lipoproteins (oxLDLs) are associated with increased cancer risk. We examined the direct effect of physiologic concentrations oxLDL on cancer cells. OxLDLs were cytotoxic and activate both apoptosis and autophagy. OxLDLs have ligands for peroxisome proliferator-activated receptor gamma and upregulated proline oxidase (POX) t...
Fowl pox is a viral disease of domestic and wild birds. The large size of the genome makes it a useful vector for recombinant DNA technology. Although the disease has been described in both commercial and indigenous chickens in Nigeria, data are limited on seroprevalence in free range chickens. Such data are, however, important in the design and implementation of fowl pox virus vector vaccine. ...
Using newer vaccine platforms which have been effective against malaria in rodent models, we tested five immunization regimens against Plasmodium knowlesi in rhesus monkeys. All vaccines included the same four P. knowlesi antigens: the pre-erythrocytic antigens CSP, SSP2, and erythrocytic antigens AMA1, MSP1. We used four vaccine platforms for prime or boost vaccinations: plasmids (DNA), alphav...
This study examines phenolic peroxidase (POX) in Rhizophora mangle L. leaves in order to assess its role in phenolic manipulation and H 2 O 2 scavenging. Sun-exposed and understorey leaves experiencing varying degrees of nutrient stress were analysed from an oligotrophic cay off the coast of Belize. POX activity was unaffected by growth environment, but increased throughout leaf development and...
The p53-dependent initiation of apoptosis is accompanied by the induction of proline oxidase (POX), a mitochondrial enzyme catalyzing the conversion of proline to pyrroline-5-carboxylate with the concomitant transfer of electrons to cytochrome c. However, the contribution of increased POX activity to apoptosis, if any, remains unknown. Using Adriamycin to initiate p53-dependent apoptosis, we sh...
