The Kelch-like ECH-associated protein 1 (Keap1)-NF-E2-related factor 2 (Nrf2) system is essential for cytoprotection against oxidative and electrophilic insults. Under unstressed conditions, Keap1 serves as an adaptor for ubiquitin E3 ligase and promotes proteasomal degradation of Nrf2, but Nrf2 is stabilized when Keap1 is inactivated under oxidative/electrophilic stress conditions. Autophagy-d...
The accumulation of damaged mitochondria has been proposed as a key factor in aging and the pathogenesis of many common age-related diseases, including Parkinson disease (PD). Recently, in vitro studies of the PD-related proteins Parkin and PINK1 have found that these factors act in a common pathway to promote the selective autophagic degradation of damaged mitochondria (mitophagy). However, wh...
Macroautophagy is a key stress-response pathway that can suppress or promote tumorigenesis depending on the cellular context. Notably, Kirsten rat sarcoma (KRAS)-driven tumors have been reported to rely on macroautophagy for growth and survival, suggesting a potential therapeutic approach of using autophagy inhibitors based on genetic stratification. In this study, we evaluated whether KRAS mut...
اتوفاژی یک فرایند محافظت شده در یوکاریوتها برای حذف اجزای سلولی آسیب دیده یا نا خواسته است. این مسیر در مقاومت به بیماریهای گیاهی نیز دخیل میباشد اما مکانیزم آن دقیقا مشخص نیست. در این مطالعه تاثیر دو پروتیین سرکوبگر (:Pفسفوپروتیین و :P3پروتیین فرعی 3) متعلق به ویروس موزائیک زرد راه راه جو (BYSMV) بر بیان چهار ژن مهم دخیل در اتوفاژی شامل ATG2، ATG6، ATG7 و AGO1 در ...
در سالهای اخیر نقش اتوفاژی در خاموشی آرانای القاء شده توسط ویروس از طریق فعالیت پروتئینهای سرکوبگر خاموشی آرانای به اثبات رسیده است. به منظور درک بهتر نقش احتمالی سرکوبگر خاموشی HC-Pro ویروس ای سیب زمینی در فرآیند اتوفاژی (autophagy)، اثر این سرکوبگر ویروسی روی بیان تعدادی از ژنهای مهم و دخیل در اتوفاژی مورد بررسی قرار گرفت. ژنHC-Pro ویروس ای سیب زمینی در ناقل بیان...
Perinatal asphyxia induces neuronal cell death and brain injury, and is often associated with irreversible neurological deficits in children. There is an urgent need to elucidate the neuronal death mechanisms occurring after neonatal hypoxia-ischemia (HI). We here investigated the selective neuronal deletion of the Atg7 (autophagy related 7) gene on neuronal cell death and brain injury in a mou...
Testicular heating suppresses spermatogenesis which is marked by germ cell loss via apoptotic pathways. Recently, it is reported that autophagy also can be induced by heat treatment in somatic cells. In this study, the status of autophagy in germ cells after heat treatment, as well as the partnership between autophagy and apoptosis in these cells was investigated. The results demonstrated that ...
Plant autophagy plays an important role in delaying senescence, nutrient recycling, and stress responses. Functional analysis of plant autophagy has almost exclusively focused on the proteins required for the core process of autophagosome assembly, but little is known about the proteins involved in other important processes of autophagy, including autophagy cargo recognition and sequestration. ...
