Accumulation of unusual sterile transcripts of TCRb in mouse hybridoma, murine tumour and non-human primate marmoset Ttumour

Accumulation of immunoglobulin Ig RNA (from several loci viz., CH, Ca , Jk-Ck and Sm during Igm isotype switching) in B cells and T cell receptor (TCR) RNAs (a , b and g ) in T cells of unusual sizes emanating from germline and rearranged genes were reported to accumulate in human and mouse (and murine too). The precise mechanism and function of these sterile RNA species are yet to be delineated. Similar accumulation of RNA species of unusual sizes were identified with DNA-RNA hybridization and isolation of cDNA employing with DNA and antibody probes in mouse hybridoma, murine tumour, non-human primate marmoset tumour and human leukemic cells.
