TERRA Incognita at chromosome ends.
Telomeres are transcribed in long noncoding RNA named TERRA. Although TERRA functions have been extensively investigated, the role of TERRA in telomerase recruitment and regulation is still elusive. In this issue of EMBO Reports, Moravec et al report in Schizosaccharomyces pombe that telomere shortening induces the expression of TERRA [1]. They show that polyadenylated TERRA molecules specifica...
متن کاملRetrotransposons that maintain chromosome ends.
Reverse transcriptases have shaped genomes in many ways. A remarkable example of this shaping is found on telomeres of the genus Drosophila, where retrotransposons have a vital role in chromosome structure. Drosophila lacks telomerase; instead, three telomere-specific retrotransposons maintain chromosome ends. Repeated transpositions to chromosome ends produce long head to tail arrays of these ...
متن کاملSelective Samples and the Accuracy of Screening for Intellectual Disabilities: Learning Disability Screening Questionnaire
The Learning Disability Screening Questionnaire (LDSQ) was developed primarily to provide a short and effective screening instrument to indicate possible intellectual disability amongst persons who come in contact with the service system. This study examined the validity of the Norwegian version of LDSQ in a sample of 35 subjects. All participants were outpatients referred for neuropsychologica...
متن کاملSTN1 protects chromosome ends in Arabidopsis thaliana.
Telomeres shield the natural ends of chromosomes from nucleolytic attack, recognition as double-strand breaks, and inappropriate processing by DNA repair machinery. The trimeric Stn1/Ten1/Cdc13 complex is critical for chromosome end protection in Saccharomyces cerevisiae, while vertebrate telomeres are protected by shelterin, a complex of six proteins that does not include STN1 or TEN1. Recent ...
متن کاملA learning disability screening program in a public school.
The outline of screening program for learning disabilities in a public school is presented in this paper. The screening program consisted of four standardized measures (Information Subtest of the WPPSI, SEARCH, Evanston Early Identification Scale, Bender-Gestalt) and six of the clinical observations suggested by Ayres. Forty-three kindergarten and first graders (25 males, 18 females) were teste...
