Induse jõe oru inimeste, parside, India juutide ja Tharu hõimu geneetilise põlvnemise piiritlemine
Väitekirja elektrooniline versioon ei sisalda publikatsiooneKäesolev on viies Tartu Ülikoolis valminud väitekiri Lõuna-Aasia rahvaste geneetilisest ajaloost. Asustatud kaasaegse inimese poolt märksa enne viimase jääaja maksimumi, elab tänapäeval selles regioonis üle 1.8 miljardi inimese – pea veerand inimkonnast. Seega ei ole võimalik süvitsi mõista kaasaegse inimese geneetise varieeruvuse kujunemist, sh eriti väljapool Sahara-alust Aafrikat, omamata detailsemat teadmist Lõuna-Aasia rahvaste geneetikast
Väitekiri põhineb neljal ilmunud artiklil. Neist esimeses uurisime Kirde-Indiat asustavaid rahvaid seoses võimaliku pärinevusega Induse oru kultuurist ja järgnenud vedade ajastust. Teine ja kolmas artikkel on pühendatud migratsioonidele, mis tõid Indiasse religioosses mõttes uusi rahvagruppe: parsid Iraanist alates 7. sajandi lõpupoolelt ja juudid, kelle saabumine Indiasse on toimunud mitme lainena. Neljandas artiklis on vaatluse all Nepaalis, kuid ka India põhjapoolsetes osariikides elutsev rahvarohke tharu hõim.
Esimes artikli huvitavamaks leiuks on usutavasti juba vedade ajastust tuntud Rori populatsiooni genoomis väljenduv suurem geneetiline afiinsus põhjapoolse stepivööndi rahvastega, samuti ka lääne-eurooplastega, mis räägib põhja-lõunasuunalistest migratsiooni(de)st eelajaloolisel ajal.
Parside saabumist Lõuna-Aasiasse seostatakse Iraani islamiseerumisega 7. sajandil. Võrreldes parside genoome nende ajaloolises kontekstis leidsime ulatusliku segunemise Lõuna-Aasia rahvastega, sealjuures asümeetriliselt isa ja emaliinides. Sama saab väita ka Indias judaistliku traditsiooni elemente säilitanud erinevate kogukondade kohta, kelle genoomis on siiski selgelt säilunud Lähis- ja Kesk-Ida pärandit.
Puudutavalt aga geneetiliselt ulatuslikult varieeruvat tharu hõimu, kelle hulgas on selgesti eristatav ka Ida-Aasia komponent, segunenuna Lõuna-Aasia pärandiga, paistab õigustatud olevat neid vaadelda esmajoones mitte sedavõrd deemilise, kuivõrd just kultuurilise konstruktsioonina.Presented hereby is the 5th in a series of PhD theses prepared in Tartu University, addressing genetics of population history of the South Asian peoples. Inhabited considerably before the Last Glacial Maximum, the region harbors by now about 1.8 billion humans – almost a quarter of the global population. Therefore, understanding of present-day variation of the latter, in particular outside sub-Saharan Africa, is not possible without deeper knowledge about genetics of South Asian populations.
This thesis is based on four published papers. The first one is focused on selected populations inhabiting northeastern Indus Valley, bearing, in particular, in mind ancient Indus Valley civilization and following it Vedic period. The second and the third paper address historically somewhat better known migrations, bringing to India religiously distinct Parsi and Jewish peoples. The fourth paper analyses the genetic variation of a populous Tharu tribe, living predominantly in Nepal, but also in northern provinces of India.
Perhaps the most interesting finding of the first paper is that the presumably identified already in Vedic texts, Ror population exhibits significant genetic affinity with northern Steppe and West European peoples, testifying about prehistoric north to south migration(s).
The arrival of Parsis to South Asia in 7th century was a consequence of the Islamization of Iran. Comparing Parsi genomes in their historic contexts, we observed their extensive admixture with South Asians, in particular, asymmetrically in paternal and maternal lineages. Nearly the same can be said about different Indian communities that preserved Judaist traditions: their genomes show affinities to peoples living in the Near and Middle East.
As far as the genetically highly diverse Tharu tribe is concerned, a clearly distinct East Asian contribution can be seen, admixed with South Asian genetic heritage. It seems justified to identify the Tharu as cultural, rather than demic phenomenon.https://www.ester.ee/record=b542949
Human Papillomavirus and Related Diseases
Cervical cancer is the second most prevalent cancer among women worldwide, and infection with Human Papilloma Virus (HPV) has been identified as the causal agent for this condition. The natural history of cervical cancer is characterized by slow disease progression, rendering the condition in essence preventable and even treatable when diagnosed in early stages. Pap smear and the recently introduced prophylactic vaccines are the most prominent prevention options, but despite the availability of these primary and secondary screening tools, the global burden of disease is unfortunately still very high This book will focus on the clinical and diagnostic aspects of HPV and related disease, highlighting the latest developments in this field
Biometrics
Biometrics uses methods for unique recognition of humans based upon one or more intrinsic physical or behavioral traits. In computer science, particularly, biometrics is used as a form of identity access management and access control. It is also used to identify individuals in groups that are under surveillance. The book consists of 13 chapters, each focusing on a certain aspect of the problem. The book chapters are divided into three sections: physical biometrics, behavioral biometrics and medical biometrics. The key objective of the book is to provide comprehensive reference and text on human authentication and people identity verification from both physiological, behavioural and other points of view. It aims to publish new insights into current innovations in computer systems and technology for biometrics development and its applications. The book was reviewed by the editor Dr. Jucheng Yang, and many of the guest editors, such as Dr. Girija Chetty, Dr. Norman Poh, Dr. Loris Nanni, Dr. Jianjiang Feng, Dr. Dongsun Park, Dr. Sook Yoon and so on, who also made a significant contribution to the book
Selected Works in Bioinformatics
This book consists of nine chapters covering a variety of bioinformatics subjects, ranging from database resources for protein allergens, unravelling genetic determinants of complex disorders, characterization and prediction of regulatory motifs, computational methods for identifying the best classifiers and key disease genes in large-scale transcriptomic and proteomic experiments, functional characterization of inherently unfolded proteins/regions, protein interaction networks and flexible protein-protein docking. The computational algorithms are in general presented in a way that is accessible to advanced undergraduate students, graduate students and researchers in molecular biology and genetics. The book should also serve as stepping stones for mathematicians, biostatisticians, and computational scientists to cross their academic boundaries into the dynamic and ever-expanding field of bioinformatics
Frameshift mutations at the C-terminus of HIST1H1E result in a specific DNA hypomethylation signature
BACKGROUND: We previously associated HIST1H1E mutations causing Rahman syndrome with a specific genome-wide methylation pattern. RESULTS: Methylome analysis from peripheral blood samples of six affected subjects led us to identify a specific hypomethylated profile. This "episignature" was enriched for genes involved in neuronal system development and function. A computational classifier yielded full sensitivity and specificity in detecting subjects with Rahman syndrome. Applying this model to a cohort of undiagnosed probands allowed us to reach diagnosis in one subject. CONCLUSIONS: We demonstrate an epigenetic signature in subjects with Rahman syndrome that can be used to reach molecular diagnosis
