1) Le variazioni di sequenza del DNA mitocondriale e del cromosoma Y come marcatori d'origine etnica e di antiche interazioni tra popolazioni umane. Al momento della fecondazione lo zigote riceve metà del DNA dalla madre e metà dal padre. Il contributo dello spermatozoo differisce però da quello della cellula uovo per due caratteristiche distinte e complementari:
(a) non fornisce mitocondri vitali, che pure possiedono un proprio genoma circolare (~16570 paia di basi), per cui il DNA mitocondriale (mtDNA) è trasmesso per sola via materna;
(b) solo lo spermatozoo fornisce il cromosoma Y in metà delle fecondazioni (dando vita a embrioni maschili), e pertanto il cromosoma Y è trasmesso per sola via paterna.
L'mtDNA e la porzione non-ricombinante del cromosoma Y (NRY) non ricombinano durante la meiosi, e ciò fa si che, nel caso della specie umana, il primo sia un registro molecolare della "storia" delle donne, attraverso le quali è stato trasmesso, mentre il secondo riassuma la "storia" dei maschi. Quindi, questi due sistemi di trasmissione uniparentale forniscono informazioni genetiche complementari, che possono essere confrontate sia tra loro, sia con quelle ottenute dal cromosoma X e dagli autosomi. Data l'assenza di ricombinazione, il differenziamento dell'mtDNA e della regione NRY è avvenuto solo per l'accumulo sequenziale di nuove mutazioni lungo linee di radiazione, nel primo caso esclusivamente materne, nel secondo esclusivamente paterne. Nel corso del tempo questo processo di divergenza molecolare ha dato origine a entità monofiletiche che sono ora chiamate aplogruppi. Poiché il processo di differenziazione molecolare è avvenuto in gran parte durante e dopo il processo di colonizzazione umana delle varie regioni e continenti, gli aplogruppi e i sub-aplogruppi tendono a essere limitati a specifiche aree geografiche e gruppi di popolazioni. Quindi l'identificazione molecolare degli aplogruppi, la quantificazione della loro variabilità interna, e l'analisi della loro distribuzione etnico-geografica possono fornire dati importanti sull'origine dell'Uomo e sui processi genetici e demografici che hanno generato le popolazioni moderne.
2) Il ruolo della variazione di sequenza "normale" dell'mtDNA nell'espressione di malattie/fenotipi: analisi di sequenza completa di mtDNA rappresentativi di tutti gli aplogruppi umani. La produzione di ATP mitocondriale mediante la fosforilazione ossidativa è essenziale per il mantenimento delle normali funzione di organi e tessuti e sono note numerose mutazioni del DNA mitocondriale (mtDNA) che, interferendo con la sintesi di ATP, causano serie patologie a trasmissione materna. Le mutazioni patologiche dell'mtDNA identificate finora erano probabilmente le più facili da evidenziare e, secondo molti, rappresentano solo la frazione più estrema di un gruppo molto più ampio di mutazioni che pur essendo "naturali" non sono necessariamente "neutrali". In anni recenti, un ruolo della variazione di sequenza "naturale" dell'mtDNA è stato postulato per numerose altre patologie e fenotipi (compreso il processo di invecchiamento) che mancano di un chiaro pattern di trasmissione, e si è ipotizzato che i genotipi "naturali" dell'mtDNA (che possono essere molto divergenti l'uno dall'altro a causa dell'elevato tasso evolutivo dell'mtDNA) possano modulare l'espressione non solo delle mutazioni patologiche dell'mtDNA, ma anche dei genotipi nucleari. E' opinione comune che per verificare queste ipotesi occorra acquisire nuovi dati sulla variazione di sequenza di questi genotipi mitocondriali, e questi si possono ottenere solo mediante sequenziamento di interi genomi mitocondriali. Il nostro laboratorio sta sequenziando questi genomi allo sopo di creare un database di sequenze che includa sequenze complete per ciascuno degli aplogruppi e sottoaplogruppi mitocondriali presenti nella nostra specie (per un totale di parecchie centinaia di sequenze complete).
