Murine genes encoding the seven H1 histone isoforms H1.1-H1.5, H1(o) and H1t have been isolated and sequenced. We have established expression patterns of these genes in several tissues during postnatal development. For that analysis, RNase protection assay rather than Northern blot hybridization was used, since the sequences of these genes are highly similar and would cross-hybridize under Northern blot conditions. Expression patterns of H1.1 to H1.5 and H1(o) were determined in tissues of animals at days 5, 9 and 20 after birth and of adult mice. In addition, RNA was analyzed in three mouse cell lines (NIH3T3, P19, TM4). Transcription of the subtype genes H1.2 and H1.4 was found in all tissues and cell lines studied. The most varied expression patterns were obtained with the H1.1 subtype. H1.1 mRNA was found at high concentrations in thymus and spleen throughout development and in testis beginning with a low expression in 5-day-old animals and increasing levels in testis RNA from 9- and 20-day-old and adult mice. H1(o) mRNA was found primarily in highly differentiated tissues with concentrations decreasing from 5-day-old to adult animals.

The histone gene H1t is expressed exclusively in pachytene spermatocytes of the testis. In this report we have eliminated the single copy H1t gene by homologous recombination from the mouse genome to analyse the function of the H1t protein during spermatogenesis. Mice homozygous for the mutated H1t gene locus developed normally and showed no anatomic abnormalities until the adult stage. In addition, H1t-deficient mice were fertile and reproduced as wild-type mice. The process of spermatogenesis and the testicular morphology remained unchanged in the absence of H1t. RNase protection analysis demonstrated that H1.1, H1.2 and H1.4 histone gene expression is enhanced during spermatogenesis in H1t-deficient mice.
