This invention is in the field of lymphadenopathy virus. This invention relates to a diagnostic means and method to detect the presence of DNA, RNA, or antibodies of the lymphadenopathy retrovirus associated with the acquired immune deficiency syndrome or of the lymphadenopathy syndrome by the use of DNA fragments or the peptides encoded by said DNA fragments. The invention further relates to the DNA fragments, vectors comprising them, and the proteins expressed.

This invention is in the field of lymphadenopathy virus. This invention relates to a diagnostic means and method of detecting lymphadenopathy associated virus or related viruses or DNA pro-viruses with cloned DNA sequences which are hybridizable to genomic RNA and DNA of lymphadenopathy associated virus. It further relates to the cloned DNA sequences and a process for their preparation.

The inventors have isolated cloned cDNA encoding the RNA genome of Human Immunodeficiency Virus type 1 (HIV-1). Various clones are described, which encode different regions of the genome, including those regions encoding viral antigens or proteins. Hybridization results indicate the difference between the HIV-1 clones and those of HTLV-I and HTLV-II. The inventors have also produced a restriction map of the entire cloned genomic sequence in order to facilitate further subcloning and using the restriction fragments in other hybridization tests and in methods to express encoded sequences.

Method for detecting human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) activity

This invention is in the field of lymphadenopathy virus, which has been designated Human Immunodeficiency Virus Type 1 (HIV-1) to detect the presence of DNA, RNA or antibodies of the lymphadenopathy retrovirus associated with the acquired immune deficiency syndrome or of the lymphadenopathy syndrome by the use of DNA fragments or the peptides encoded by said DNA fragments. The invention further relates tot he DNA fragments, vectors comprising them and the proteins expressed.

Recombinant DNA modified by a nucleotide sequence coding for a specific polypeptide sequence whose expression is sought, this recombinant DNA being appropriate to the transformation of eucaryotic cell lines, notably human or animal, the endogenous polymerases of which are susceptible of recognizing the adenovirus promoters. The DNA according to the invention is more particularly characterized by the fact that the said insertion nucleotide sequence is placed under the direct control of the early promoter of the E1A region of the genome of adenovirus.

A previously isolated hepatitis B virus (HBV) integration in a 147 bp cellular DNA fragment linked to hepatocellular carcinoma (HCC) was used as a probe to clone the corresponding complementary DNA from a human liver cDNA library. Nucleotide sequence analysis revealed that the overall structure of the cellular gene, which has been named hap, is similar to that of the DNA-binding hormone receptors. Six out of seven hepatoma and hepatoma-derived cell-lines express a 2.5 kb hap mRNA species which is undetectable in normal adult and fetal livers, but present in all nonhepactic tissues analyzed. Low stringency hybridization experiments revealed the existence of hap related genes in the human genome. The cloned DNA sequence is useful in the preparation of pure hap protein and as a probe in the detection and isolation of complementary DNA and RNA sequences. The hap protein is a retinoic acid (RA) receptor identified as RAR-&bgr;.
