[Thyroglobulin gene expression in human thyroid cells in various types of thyroid pathology].

Highly purified thyroglobulin mRNA was isolated from human nodal euthyroid goiter. Full length cDNA was synthesized from 33S RNA by using reverse transcriptase in the presence of human placenta ribonuclease inhibitor. DNA complementary to human Tg mRNA was used in liquid hybridization experiments to determine the quantity of Tg mRNA.

[Mapping of the thyroglobulin gene in high molecular weight DNA from the human thyroid in normal conditions and in thyroid pathology].

A highly purified thyroglobulin (Tg) mRNA was isolated from human nodal euthyroid goiter. Ultracentrifugation in a 5-20% sucrose density gradient revealed that the protein has a sedimentation coefficient of 33S. cDNA was synthesized from the 33S RNA, using reverse transcriptase in the presence of a human placental ribonuclease inhibitor.

[Use of growth hormone genes for the diagnosis of the disease of dwarfism].

The pattern of BamHI fragments of DNA from three children suggested to suffer the isolated growth hormone deficiency type. IA was not different from normal pattern registered in blot hybridization with [32P]cDNA of the growth hormone gene. The data permits one to exclude the above mentioned disease that is characterized by the deletion of HGH-N gene.
