  • Patent number: 8273722
    Abstract: Compositions, kits, systems, equipment, and protocols utilize synthetic siRNA having a delivery facilitating moiety in improved bioprocesses that enhance the production of biomaterials. The siRNA can target genes associated with the following: 1) deleterious vector derived genes; 2) genes that confer non-optimal growth or differentiation properties to the cells; 3) genes that can influence heterogeneity or post-translational modification pattern of the desirable gene product; 4) genes that highly express non-desired proteins; 5) genes that express proteins which interfere with purification of the desired protein; and 6) other genes that can interfere with the bioprocess.

  • Publication number: 20100184209
    Abstract: The present invention provides compositions and methods for inhibiting gene silencing by the RNAi pathway. The RNAi inhibitors of the invention have a reverse complement (RC) region to the target molecule of interest (e.g., miRNA) in association with at least one flanking region coupled to either at the 3? or 5? end of the RC region. The flanking regions can be single-stranded or can have one or more regions of double stranded nucleic acid with or without a hairpin loop. The RNAi inhibitors described herein can inhibit endogenous targets, including but not limited to microRNAs, or piRNAs, or can be used to inhibit the effects of exogenously introduced molecules, such as synthetic siRNAs, siRNAs expressed from vector constructs (e.g., viral expression systems), or siRNAs generated by enzymatic methods. Inhibition is specific, potent, prolonged, and can be performed on a single target or multiple targets simultaneously.
