Jaunu ģenētisko variantu funkcionāla raksturošana izmantojot izolētas pacientu šūnas
2022
Mutācijas gan mitohondriālajā DNS, gan kodola DNS var izraisīt traucējumus mitohondriju oksidatīvās fosforilēšanas sistēmā, kas var būt cēlonis smagām mitohondriālajām slimībām. Mitohondriālo slimību diagnostika ir komplicēta, un tai izmanto lielu laboratorijas metožu klāstu. Darba “JAUNU ĢENĒTISKO VARIANTU FUNKCIONĀLA RAKSTUROŠANA IZMANTOJOT IZOLĒTAS PACIENTU ŠŪNAS” mērķis ir raksturot jaunus ģenētiskos variantus reto ģenētisko slimību pacientiem, izmantojot molekulārās un bioķīmiskās metodes, kā arī perifēros leikocītus un kultivētus fibroblastus. Tika veikta DNS variantu validācija ar Sangera sekvencēšanu, šūnu līniju izveidošana un kultivēšana, mitohondriju izdalīšana no šūnu kultūrām u…
Whole mitochondrial genomes unveil the impact of domestication on goat matrilineal variability
2015
Background The current extensive use of the domestic goat (Capra hircus) is the result of its medium size and high adaptability as multiple breeds. The extent to which its genetic variability was influenced by early domestication practices is largely unknown. A common standard by which to analyze maternally-inherited variability of livestock species is through complete sequencing of the entire mitogenome (mitochondrial DNA, mtDNA). Results We present the first extensive survey of goat mitogenomic variability based on 84 complete sequences selected from an initial collection of 758 samples that represent 60 different breeds of C. hircus, as well as its wild sister species, bezoar (Capra aega…

Shedding Light on the Dark Ages: Sketching Potential Trade Relationships in Early Medieval Romania through Mitochondrial DNA Analysis of Sheep Remains
2021
Southeast Europe has played an important role in shaping the genetic diversity of sheep due to its proximity to the Danubian route of transport from the Near East into Europe, as well as its possible role as a post-domestication migration network and long tradition of sheep breeding. The history of Romania and, in particular, the historical province of Dobruja, located on the shore of the Black Sea, has been influenced by its geographical position at the intersection between the great powers of the Near East and mainland Europe, with the Middle Ages being an especially animated time in terms of trade, migration, and conflict. In this study, we analyzed the mitochondrial control region of fi…
The EDNAP mitochondrial DNA population database (EMPOP) collaborative exercises: organisation, results and perspectives.
2003
This paper presents an overview of the organisation and the results of the collaborative exercises (CE) of the European DNA Profiling (EDNAP) Group's mitochondrial DNA population database project (EMPOP). The aim of the collaborative exercises was to determine whether uniformity of mtDNA sequencing results could be achieved among different laboratories. These were asked to sequence either the complete mtDNA control region or the two hypervariable regions HVI (16024-16365) and HVII (73-340) from DNA extracts, buccal swabs or bloodstains, proceeding in accordance with the protocol and strategies used in each individual laboratory. The results of the collaborative exercises were employed to id…
Cryptic species within the freshwater copepod genus Hemidiaptomus (calanoida, diaptomidae).
2009
The copepod genus Hemidiaptomus is composed by about 17 large-bodied species inhabiting the freshwater temporary water bodies of the whole Palaearctic region. It currently comprises three subgenera, which are mostly parapatric and present only limited co-occurrence areas. There is no consensus on the taxonomical arrangement of the entire group, and to date no molecular studies have been carried out to test it. Accordingly, a thorough revision of the entire genus using a combined morphological and molecular approach is strongly advisable. We have thus decided to investigate the pattern of morphological and molecular diversity of three species of the genus Hemidiaptomus belonging to the three…
