  • Methods for in vitro investigating mitochondrial replication dysfunction in a biological sample, kits and uses thereof, therapeutic methods against progeroid-like syndromes or symptoms and screening method for identifying particular protease inhibitor(s) and/or nitroso-redox stress scavenger compound(s)
    Patent number: 11287433
    Abstract: The invention relates to a method for in vitro investigating mitochondrial replication dysfunction in a biological sample removed from a subject susceptible of suffering from physiological ageing or physiopathological conditions related to physiological ageing, or physiopathological ageing or associated symptoms or conditions, in particular premature ageing or accelerated ageing, or of a progeroid syndrome, such as Cockayne syndrome (CS), or neurodegenerative disorders or symptoms thereof, in which the levels of at least one species selected in the group of: POLG1 protein, POLG1 RNA, POLG2 protein, protease(s) which have POLG as a target, in particular serine protease(s) such as HTRA3 protein, HTRA2 protein and, HTRA3 RNA or HTRA2 RNA, or any combination of these species, are investigated.

  • Stable and long-lasting siRNA expression vectors and the applications thereof
    Patent number: 7973155
    Abstract: The invention relates to a siRNA expression vector that can inhibit or eliminate the expression of a target gene in a mammalian cell, said vector comprising: a bacterial cassette containing a bacterial origin of replication and a bacterial selection marker M1; a eucaryotic cell selection cassette comprising a marker M2 for selecting eucaryotic cells under the control of an appropriate promoter; a cassette EBV comprising at least one fragment of the antigen EBNA-1, at least one fragment FR, and at least one fragment of the region DYAD; and a siRNA transcription cassette comprising at least one region coding for a siRNA corresponding to the target gene to be inhibited or eliminated, under the control of elements for regulating transcription in mammalian cells, said regulating elements including at least one promoter capable of transcribing a siRNA in mammalian cells, and a transcription terminator. The invention also relates to the applications of one such expression vector.
