Compensatory Hypertrophy of Thymus Gland

We recently have reported several studies concerning the marked stimulation of growth and regeneration that occurs in the thymus gland of rats, of any age, following double suprarenalectomy (1-3). We showed that, as the result of such a procedure, marked hyperplasia of the involuting thymus, with enlargement of the same, occurs with great constancy. In line with these studies, we undertook a se...

Purification of terminal riboadenylate transferase from calf thymus gland.

A poly(A) polymerase has been purified from the soluble protein fraction of calf thymus gland. The activity is cytoplasmic and nonparticulate. Mn-2+ATP is the preferred substrate. On the basis of disc gel electrophoresis in sodium dodecyl sulfate-acrylamide gels, gel filtration, and sedimentation velocity in sucrose gradients, the enzyme has a molecular weight of 62,000 and appears to consist o...

Metabolic properties of histones from rat liver and thymus gland.

1. The incorporation of (14)C-labelled amino acids into acid-extractable proteins from rat-liver and -thymus nuclei confirmed the existence of a protein component with a higher uptake than that into the major histone components. 2. This rapidly labelled component appeared to contain the thiol groups detectable in the acid extracts. 3. Histone f1 contained 1mol. of serine phosphate/mol. of mol.w...

Deoxynucleotide-polymerizing Enzymes of Calf Thymus Gland

Replication of polydeoxyadenylate and polydeoxythymidylate catalyzed by the high molecular weight DNA polymerase proceeds only in the presence of a complementary oligodeoxynucleotide. The oligodeoxynucleotide initiator chain must be greater than 6 nucleotides for poly(dA) replication and greater than 5 nucleotides for poly(dT) replication. The initiator oligonucleotide is incorporated into prod...
