The transformed cells are indifferent to reagents noncomplementary to the E1 region. Thus polyalkylating derivatives of single-stranded 30-200-mers act as addressed mutagenes which react in a specific way with the integrated complementary DNA sequences of E1 oncogene in transformed rodent cells and realize oncogene-directed mutagenesis in vivo. During this treatment temporary normalized cells reverting to the initial transformed phenotype are also produced.

Analysis of the nucleotide sequence, carried out in four DNA fragments after the enzymatic hydrolysis' enabled to detect the only one common 13 residues nucleotide sequence, which is apparently involved in the recognizing site for vestrictase Eco CK: (A/T) (A/T) N (A/T) CGCNCNNNG. This sequence was not found in several DNA molecules with well-known primary structure, stable to the action of this enzyme.

Treatment of rodent cell cultures transformed by oncogenic SA7 with polyalkylating oligomers which are complementary to the long region of the minus or plus chains of E1 DNA of SA7 revealed a rather high extent of mutant cell clones formation. The cells formed were normalized; they had lost some properties of the transformed cells. Dividing cell clones inherited the new phenotypic properties: morphology, slower and more limited proliferation, and higher dependence on bovine serum growth factors. Some of the mutant cell DNAs demonstrated different mutations in the E1A sequences of the integrated proviral oncogene. There were exchanges G to C (leu to val) in the 525 and C to A (asp to tyr) in the 555 positions of E1A oncogene. Besides a deletions in the 1057-1477 E1A region or/and a mutation in the 1457-1477 of E1A were observed. Thus the inherited cell normalization observed is performed due to oncogene-directed mutagenesis in vivo.

Focus forming transformants were cloned with a final dilution technique and a new cell line G11 was created as a result. Transformed status of this cell line is evidenced by changes in morphology, specific cytochemical and adhesion properties, ability to grow in semisolid agar and FCS concentration growth independence. Presence of intact integrated E1a-region of adenovirus SA7 oncogene was shown by blot-hybridization technique. Transformed status of G11 cells can be explained by integration of SA7 oncogene, that is evidenced indirectly by the increased resistance to heat shock.

Single-stranded DNAs of the recombinant phages thus obtained (mp8G and mp9G) partially digested with DNAse II were used to synthesize polyalkylating derivatives capable of specific hybridisation and subsequent alkylation of complementary G sequences of corresponding phage DNAs. After incubation of complementary alkylated DNA in the presence of lysine, the preselected region (G fragment) was specifically eliminated without damaging vector sequences. The method of complementary-addressed cleavage proved to be useful for precise analysis of reactions of polyalkylating derivatives within complementary complexes.

It can be used for rapid and effective diagnosis of hemophilia A, especially, in combination with the blot-hybridization technique that detects other polymorphic variants of FVIII gene. The method proposed is highly accurate, reliable and simple. It allows one to analyze submicrogram quantities of DNA without using radiolabeled probes. The whole procedure takes several hours. The variant discussed can, possibly, be the part of the general scheme of hemophilia diagnosis completely based on the effective PCR test.

Derivatives penetrate the SH2 cells and their distribution in the subcellular fractions are proportional to the concentration of reagent in the medium. The transport efficiency of the derivatives is inhibited sharply with cell concentration increase and practically does not depend on the action of cell metabolism inhibitors. The data obtained assumes the mechanism of the derivatives transport to be liquid endocytosis. Being distributed in the cell components the polyalkylating derivatives were accumulated by the cell nuclei up to 10(5)-10(7) molecules per nucleus. Transport efficiency is much greater in the anchored cells than in the suspended ones. Though essential dephosphorylation of the utilized substances is observed in the SH2 cells, part of them maintain native chain length and the 5'-phosphate group after 1 h incubation in nucleic acids obtained from the cell nuclei.

For the latter the primers derived from exon 19 and 20 sequences allowed to amplify the whole intron 19 resulting in a 730 bp fragment. Hind III restriction of this fragment provides polymorphic fragments of 250 bp or 160 bp and 90 bp respectively. An also occurring 480 bp fragment can be used as internal control to circumvent misdiagnosis due to incomplete or failure of restriction. The Hind III polymorphism was successfully used in prenatal diagnosis of an affected male in the first trimenon of pregnancy. Fetal sexing was also performed by PCR technique using Y specific primers.

The sensitivity determined by amplification of DNA mixture in dilutions was 1-2%. Based on the data obtained, various types of hemopoiesis recovery after bone marrow transplantation were determined; in most cases, a complete donor chimerism was revealed; in some patients, mixed chimerism; and in one case, a host type of hemopoiesis was found. An association between hemopoiesis type and further development of the disease was observed.

Due to the insert sequencing and blotting of human leukocytes DNA, the DNA probes obtained can be useful for screening of mutations in the human CSF-1 gene.

It was shown that the heterozygosity index of this polymorphism in the studied population is much lower (0.71) than in Western Europe (0.80-0.85), which can apparently be explained by a higher frequency of the prevailing allele 1690 (0.52 compared to 0.36). Five new St14 alleles were detected during this study. The total informativity of the polymorphic markers St14 and HindIII (intron 19 of the factor VIII gene), which are most commonly used for hemophilia A detection, was evaluated. Among 83 investigated women, only 57 (69%) were heterozygous for at least one of the markers used, which is also much lower than in Western-European populations (90-95%).

The tRNA incorporation determined after tRNA hydrolysis on cell surface by RNAase increases linearly with a rise in the initial concentration from 0.5 to 500 micrograms per ml. According to gel electrophoresis of intracellular nucleic acids, after a 3 hour incubation the [32P]tRNA incorporated into the cells by 50% to form tRNA fragments without any conspicuous reutilization. The kinetic curve of tRNA incorporation during the first 60 min demonstrates a severalfold decrease in the initial maximal incorporation of [32P]tRNA into the cells (2 min), with a subsequent restoration of the incorporation within 2-3 hours.

Integration of the gene was tested by polymerase chain reaction. The effect of the procedure averaged 50-80% of marked CFUc. Electroporation did little damage to hemopoietic cell precursors. Gene transfer can be made most effectively using bone marrow from mice injected 5-fluorouracil 4 days prior to the experiment.

The existence of marker gene in stromal cells was established by the method of polymerase chain reaction. The transduced stromal precursor cells create normal haemopoietic microenvironment.

Cultures were infected six times during the first 3 weeks of cultivation. At 4 weeks, the adherent cell layers (ACLs) were implanted under the renal capsule of syngeneic unirradiated and irradiated mice. Cells from newly formed ectopic foci were explanted into secondary LTBMC. ACLs containing the marker gene were detected by polymerase chain reaction. About 74% of stromal cells in ACLs contained Neor gene. The possibility of stable gene transduction into stromal precursor cells competent to transfer the hematopoietic microenvironment was established.
