Human T-cell leukemia virus IIMo (HTLV-IIMo) is a human retrovirus isolated from a patient with a T-cell hairy cell leukemia. This virus has been shown to have core protein (gag) antigens similar to, but distinct from, those of all known isolates of the prototype human T-cell leukemia virus (HTLV-I). We have used a subgenomic clone of the HTLV-I env-pX region to detect and characterize HTLV-IIMo proviral sequences by performing Southern blot hybridization under conditions of low stringency. Using the HTLV-I probe, we cloned a partial integrated HTLV-IIMo provirus from a genomic library of the producer Mo cell line. These sequences could be characterized by low stringency hybridization with different subgenomic clones of HTLV-I. An HTLV-IIMo-specific subclone was made by isolating a 3.6-kilobase BamHI fragment of the partial provirus. This was used to clone two full-length integrated viral genomes. Using the HTLV-IIMo viral probe, we also showed by hybridization under stringent conditions to DNA and RNA of various infected and uninfected cell lines that these HTLV-IIMo sequences are unique.

UI	MeSH Term	Description	Entries
D007943	Leukemia, Hairy Cell	A neoplastic disease of the lymphoreticular cells which is considered to be a rare type of chronic leukemia; it is characterized by an insidious onset, splenomegaly, anemia, granulocytopenia, thrombocytopenia, little or no lymphadenopathy, and the presence of "hairy" or "flagellated" cells in the blood and bone marrow.

D009693	Nucleic Acid Hybridization	Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

D003001	Cloning, Molecular	The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.	Molecular Cloning
D004262	DNA Restriction Enzymes	Enzymes that are part of the restriction-modification systems. They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another.
