Nrf2 and p21 regulate the fine balance between life and death by controlling ROS levels.
On the other hand, p21 facilitates apoptotic processes when DNA damage is beyond repair. 8 Furthermore, cellular stress that does not damage DNA, such as hypoxia or exposure to ribonucleotide biosynthesis inhibitors, may also induce p53-dependent expression of p21. 7 In our recent study, 9 we have revealed a novel mechanism by which p21 protects cells against oxidative stress through upregula-t...
متن کاملThe Balance between Life and Death of Cells: Roles of Metallothioneins
Metallothionein (MT) is a highly conserved, low-molecular-weight, cysteine-rich protein that occurs in 4 isoforms (MT-I to MT-IV), of which MT-I+II are the major and best characterized proteins.This review will focus on mammalian MT-I+II and their functional impact upon cellular survival and death, as seen in two rather contrasting pathological conditions: Neurodegeneration and neoplasms. MT-I+...
متن کاملMetabolic sensing by p53: keeping the balance between life and death.
T here is no life without stress, and there is no life without mechanisms for adaptation to stress. Stress perturbs the balance of a living system, thereby scrutinizing the plasticity of its regulatory networks. These networks shape the composition and behavior of living systems. Biological networks serve the adaptability of the whole system, wherein multiple sensors and effectors cooperate to ...
متن کاملthe relationship between collocational competence and listening comprehension
پس از پیدایش روش تدریس tpr توسط جیمز اشر که توجه و تآکید بسیاری بر مهارت شنیداری داشت زبانشناسان همواره در صدد یافتن راههایی برای بهبود این مهارت در زبان آموزان می باشند. از طرفی جی-آر-فرث که از پیشگامان زبانشناسی می باشد بر تآثیر لغات و بویژه گروه کلمات که اغلب در گفتار با هم می آیند (هم آیی کلمات)تأکید بسیار کرده است. به این دلیل و به منظوربررسی رابطه بین این دو عامل یعنی درک شنیداری و دانش...
15 صفحه اولthe relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
