Ross,27 Mina Ryten,8,28,29 Ali Torkamani,30 Toshiko Tanaka,31 Luigi Ferrucci,31 Susan M. Resnick,32 We examined the role of repeat expansions in the pathogenesis of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) by analyzing whole-genome sequence data from 2,442 FTD/ALS patients, 2,599 Lewy body dementia (LBD) patients, and 3,158 neurologically healthy subjects. Pathogenic expansions (range, 40?64 CAG repeats) in the huntingtin (HTT) gene were found in three (0.12%) patients diagnosed with pure FTD/ALS syndromes but were not present in the LBD or healthy cohorts. We replicated our findings in an independent collection of 3,674 FTD/ALS patients. Postmortem evaluations of two patients revealed the classical TDP-43 pathology of FTD/ALS, as well as huntingtin-positive, ubiquitin-positive aggregates in the frontal cortex. The neostriatal atrophy that pathologically defines Huntington?s disease was absent in both cases. Our findings reveal an etiological relationship between HTT repeat expansions and FTD/ALS syndromes and indicate that genetic screening of FTD/ALS patients for HTT repeat expansions should be considered.

We examined the role of repeat expansions in the pathogenesis of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) by analyzing whole-genome sequence data from 2,442 FTD/ALS patients, 2,599 Lewy body dementia (LBD) patients, and 3,158 neurologically healthy subjects.

Postmortem evaluations of two patients revealed the classical TDP-43 pathology of FTD/ALS, as well as huntingtin-positive, ubiquitin-positive aggregates in the frontal cortex. The neostriatal atrophy that pathologically defines Huntington's disease was absent in both cases. Our findings reveal an etiological relationship between HTT repeat expansions and FTD/ALS syndromes and indicate that genetic screening of FTD/ALS patients for HTT repeat expansions should be considered
Genome-wide structural variant analysis identifies risk loci for non-Alzheimerās dementias
We characterized the role of structural variants, a largely unexplored type of genetic variation, in two non-Alzheimerās dementias, namely Lewy body dementia (LBD) and frontotemporal dementia (FTD)/amyotrophic lateral sclerosis (ALS). To do this, we applied an advanced structural variant calling pipeline (GATK-SV) to short-read whole-genome sequence data from 5,213 European-ancestry cases and 4,132 controls. We discovered, replicated, and validated a deletion in TPCN1 as a novel risk locus for LBD and detected the known structural variants at the C9orf72 and MAPT loci as associated with FTD/ALS. We also identified rare pathogenic structural variants in both LBD and FTD/ALS. Finally, we assembled a catalog of structural variants that can be mined for new insights into the pathogenesis of these understudied forms of dementia

Conceptualizing Green Education Awareness in Primary School to Promote Sustainability
This research aims to make environmental awareness and action an intrinsic part of life at school. This should include the students, teachers, non-teaching staff, and parents, as well as the Local Authority, the media, and local business. Green education endeavors to extend learning beyond the classroom and develop responsible attitudes and commitment. Schools consume enormous quantities of paper and energy, produce tons of waste and carbon emissions, and rarely purchase environmentally friendly products. Schools use cleaners and pesticides with neurological and reproductive toxins, which are dangerous. Poor indoor air quality and nutrition at school are linked to soaring asthma and childhood obesity rates. Research now shows that greener, sustainable school environments can save money and resources, expand learning, and improve health. And ultimately, sustainable schools teach children to become good environmental citizens and will empower them to make a difference in the environment
Structural enzymology binding studies of the peptideāsubstrateābinding domain of human collagen prolyl 4āhydroxylase (typeāII):high affinity peptides have a PxGP sequence motif
Abstract
The peptideāsubstrateābinding (PSB) domain of collagen prolyl 4āhydroxylase (CāP4H, an Ī±2Ī²2 tetramer) binds prolineārich procollagen peptides. This helical domain (the middle domain of the Ī± subunit) has an important role concerning the substrate binding properties of CāP4H, although it is not known how the PSB domain influences the hydroxylation properties of the catalytic domain (the Cāterminal domain of the Ī± subunit). The crystal structures of the PSB domain of the human CāP4H isoform II (PSBāII) complexed with and without various short prolineārich peptides are described. The comparison with the previously determined PSBāI peptide complex structures shows that the CāP4HāI substrate peptide (PPG)3, has at most very weak affinity for PSBāII, although it binds with high affinity to PSBāI. The replacement of the middle PPG triplet of (PPG)3 to the nonhydroxylatable PAG, PRG, or PEG triplet, increases greatly the affinity of PSBāII for these peptides, leading to a deeper mode of binding, as compared to the previously determined PSBāI peptide complexes. In these PSBāII complexes, the two peptidyl prolines of its central P(A/R/E)GP region bind in the Pro5 and Pro8 binding pockets of the PSB peptideābinding groove, and direct hydrogen bonds are formed between the peptide and the side chains of the highly conserved residues Tyr158, Arg223, and Asn227, replacing water mediated interactions in the corresponding PSBāI complex. These results suggest that PxGP (where x is not a proline) is the common motif of prolineārich peptide sequences that bind with high affinity to PSBāII
Crystal structure of the collagen prolyl 4-hydroxylase (C-P4H) catalytic domain complexed with PDI: Toward a model of the C-P4H tetramer
Collagen prolyl 4-hydroxylases (C-P4H) are tetramers, which catalyze the prolyl 4-hydroxylation of procollagen, allowing for the formation of the stable triple-helical collagen structure in the endoplasmic reticulum. The C-P4H -subunit provides the N-terminal dimerization domain, the middle peptide-substrate-binding (PSB) domain, and the C-terminal catalytic (CAT) domain, whereas the -subunit is identical to the enzyme protein disulfide isomerase (PDI). The structure of the N-terminal part of the -subunit (N-terminal region and PSB domain) is known, but the structures of the PSB-CAT linker region and the CAT domain as well as its mode of assembly with the /PDI subunit, are unknown. Here, we report the crystal structure of the CAT domain of human C-P4H-II complexed with the intact /PDI subunit, at 3.8 Ć
resolution. The CAT domain interacts with the a, bā, and aā domains of the /PDI subunit, such that the CAT active site is facing bulk solvent. The structure also shows that the C-P4H-II CAT domain has a unique N-terminal extension, consisting of Ī±-helices and a -strand, which is the edge strand of its major antiparallel -sheet. This extra region of the CAT domain interacts tightly with the /PDI subunit, showing that the CAT-PDI interface includes an intersubunit disulfide bridge with the aā domain and tight hydrophobic interactions with the bā domain. Using this new information, the structure of the mature C-P4H-II tetramer is predicted. The model suggests that the CAT active-site properties are modulated by -helices of the N-terminal dimerization domains of both subunits of the -dimer
