摘要:
The invention provides methods and compositions for the expression of small RNA molecules within a cell using a lentiviral vector. The methods can be used to express doubles stranded RNA complexes. Small interfering RNA (siRNA) can be expressed using the methods of the invention within a cell, which are capable of down regulating the expression of a target gene through RNA interference. A variety of cells can be treated according to the methods of the invention including embryos, embryogenic stem cells, allowing for the generation of transgenic animals or animals constituted partly by the transduced cells that have a specific gene or a group of genes down regulated.
摘要:
Cytomegalovirus (CMV) Intron A fragments for expressing gene products are disclosed. Also described are expression vectors including the fragments, as well as methods of using the same.
摘要:
The invention relates to reporter systems for RNA export, to a method for locating molecules which influence RNA export and to a technique for detecting a virus infection which is based on this method.
摘要:
Disclosed are novel bactericidal/permeability-increasing (BPI) protein products wherein cysteine residue number 132 or 135 is replaced by another amino acid residue, preferably an alanine or serine residue and/or wherein the leucine residue at position 193 is the carboxy terminal residue. Also disclosed are DNA sequences encoding methods for the production of the same in appropriate host cells, and stable homogeneous pharmaceutical compositions containing the analogs suitable for use in treatment of gram negative bacterial infection and its sequelae.
摘要:
Methods and compositions for screening for transdominant effector peptides and RNA molecules selected inside living cells from randomized pools are provided.
摘要:
Disclosed are replicatable viral DNA vectors encoding a site-specific DNA-altering enzyme and a DNA target recognized by the enzyme, the enzyme selectively converting, in a cell expressing the enzyme, the DNA vector to a rearranged form. The invention further relates to methods for assembling recombinant adenoviral DNAs. These methods include the steps of: providing a first linearized DNA vector including a restriction site and a cos site and a second linearized DNA vector including the restriction site, an adenoviral nucleic molecule, and a cos site; and ligating the first and second linearized DNA vectors, the ligation assembling a recombinant adenoviral DNA.
