    Genetic variation in human miRNAs : functional consequences and involvement in Cancer 

    Torruella Loran, Ignasi (Date of defense: 2016-10-28)

    Els microRNAs són importants reguladors de gens i destacats contribuïdors a la diversitat fenotípica clarament involucrats en malaltia humana. Hem analitzat la variabilitat genètica en microRNAs i como aquesta variabilitat ...

    Genetic variation in humans and chimpanzees in the prion protein gene 

    Soldevila Trepat, Marta (Date of defense: 2005-06-20)

    En el gen de la proteïna priònica, o PRNP, hem observat que el particular patró de variació que hem trobat basant-nos en dades de seqüenciació en humans es deu a selecció positiva, i que el mètode utilitzat per detectar ...

    Genetic, genomic and epigenetic alterations in congenital malformations : implications in genetic counseling 

    Serra Juhé, Clara (Date of defense: 2012-10-20)

    Mechanisms underlying congenital malformations are largely unknown despite its high incidence, affecting 2-3% of liveborn infants. A broader knowledge about the causes of birth defects would provide valuable information ...
