The invention refers to a new human liver cell line which may be used for toxicological, physiological and, in particular, gene therapeutic examinations. Fields of application are molecular biology, medicine and pharmaceutical industry. The new human liver cell line is marked positive owing to the parameters albumin and alpha-1-antitrypsin (ATT) and negative owing to alpha-fetoprotein (AFP). It has been deposited in the Deutsche Sammlung von Mikroorganismen (DSM ACC2302).

Human liver cell line

Liver-specific adenovirus expression vector

A tissue-specific, suitably liver specific vector for gene therapy of a diseased host, wherein a therapeutic gene is coupled to a promoter chemically, enzymatically, or over an antibody, packaged in a polypeptide coat, and coupled to a component of a preselected virus of the tissue to be treated, and when the tissue is liver tissue, then the virus is hepatitis B virus.

Agents for stimulating the dividing activity of mammalian cells are presented, which have as an active substance a nucleotide sequence with a complimentary sequence (anti-sense) to a domain of the mRNA of tumor suppressor retinoblastoma or p16 genes acting on cell dividing activity. For Rb, the agents are nucleotide sequences 5'-GGTTTTGGGCGGCATGAC-3' (SEQ ID NO: 1) and 5'-CTCAGTAAAAGTGAACGA-3' (SEQ ID NO: 2); a nucleotide sequence comprising 49 base pairs, wherein the domain of the mRNA comprises nucleotides 124 to 152; and a 360 base pair nucleotide wherein the domain of the mRNA comprises an Hpa I restriction endonuclease site, an ASP718 endonuclease site, a portion of the 5' untranslated domain of the Rb gene, and a first exon of the Rb gene. For p16, the agent comprises GATCCATGCT GCTCC (SEQ ID NO: 3).
