No evidence of DUI in the Mediterranean alien species Brachidontes pharaonis (P. Fisher, 1870) despite mitochondrial heteroplasmy
2022
AbstractTwo genetically different mitochondrial haplogroups of Brachidontes pharaonis (p-distance 6.8%) have been identified in the Mediterranean Sea. This hinted at a possible presence of doubly uniparental inheritance in this species. To ascertain this possibility, we sequenced two complete mitogenomes of Brachidontes pharaonis mussels and performed a qPCR analysis to measure the relative mitogenome copy numbers of both mtDNAs. Despite the presence of two very similar regions composed entirely of repetitive sequences in the two haplogroups, no recombination between mitogenomes was detected. In heteroplasmic individuals, both mitogenomes were present in the generative tissues of both sexes…
VALUTAZIONE DI ALCUNI BIOMARKERS DI STRESS OSSIDATIVO E DELLA FREQUENZA DEGLI APLOGRUPPI MITOCONDRIALI IN UNA POPOLAZIONE DI PAZIENTI CON MALATTIA DI…

La malattia di Fabry comprende una estrema varietà fenotipica in relazione con il grande numero di organi e sistemi coinvolti. La diagnosi di malattia di Fabry è complessa a causa del numero di organi/sistemi coinvolti e dei fenotipi clinici non specifici e della sua rarità. La progressione clinica della malattia si manifesta tra i 30-40 anni quando per i numerosi organi coinvolti compaiono manifestazioni cliniche quali insufficienza cardiaca, renale ed eventi cerebrovascolari. La morte di solito sopraggiunge durante la quarta/quinta decade di vita ed è secondaria all’interessamento cardiaco, renale o cerebrale anche se l’avvento della dialisi e della terapia enzimatica sostitutiva stanno s…
Mitochondrial genetic haplogroups and depressive symptoms: A large study among people in North America.
2017
Background:\ud A possible relationship between mitochondrial haplogroups and psychiatric diseases (e.g. schizophrenia and bipolar disorder) has been postulated, but data regarding depression is still limited. We investigated whether any mitochondrial haplogroup carried a significant higher risk of depressive symptoms in a large prospective cohort of North American people included in the Osteoarthritis Initiative.\ud \ud Methods:\ud Cross sectional data was derived from the Osteoarthritis Initiative. The haplogroup was assigned through a combination of sequencing and PCR-RFLP techniques. All the mitochondrial haplogroups were named following this nomenclature: H, U, K, J, T, V, SuperHV, I, W…
