The Telomerase Database
Telomerase is a ribonucleoprotein enzyme that extends DNA at the chromosome ends in most eukaryotes. Since 1985, telomerase has been studied intensively and components of the telomerase complex have been identified from over 160 eukaryotic species. In the last two decades, there has been a growing interest in studying telomerase owing to its vital role in chromosome stability and cellular immor...
متن کاملTumorogensis : The Dual Role of Telomerase
Carcinogenesis is a multistep process characterized by the gradual accumulation of genetic changes that ultimately lead to cancer. These genetic mutations can impart limitless replicative potential to the cancer cells making them immortal. Telomeres are repeat nucleotide sequence TTAGGG that are present at the end of chromosomes. Its functions are to protect the chromosomal ends and to ensur...
متن کاملFunctionally interacting telomerase RNAs in the yeast telomerase complex.
The ribonucleoprotein (RNP) enzyme telomerase from Saccharomyces cerevisiae adds telomeric DNA to chromosomal ends in short increments both in vivo and in vitro. Whether or not telomerase functions as a multimer has not been addressed previously. Here we show, first, that following polymerization, the telomerase RNP remains stably bound to its telomeric oligonucleotide reaction product. We then...
متن کاملIranian Brain Imaging Database: A Neuropsychiatric Database of Healthy Brain
Introduction: The Iranian Brain Imaging Database (IBID) was initiated in 2017, with 5 major goals: provide researchers easy access to a neuroimaging database, provide normative quantitative measures of the brain for clinical research purposes, study the aging profile of the brain, examine the association of brain structure and function, and join the ENIGMA consortium. Many prestigious databases...
