BACKGROUND: These serial processes for forming male gametes are basically controlled by the programmed expression of a number of stage-specific genes. However, many aspects of the mechanisms of spermatogenesis have remained elusive because of a lack of suitable in vitro or in vivo models.OBJECTIVE: To screen genes involved in spermatogenesis, and to analyze its expression characteristics. METHODS: Testes cDNA samples from Balb/C mice of different postnatal days (4,9,18,35, 54 days and 6 months, respectively) were hybridized with mouse whole genome Affymetrix chip to screen the testis-ralated genes. The characteristics of the selected genes were analyzed by various bioinformatics tools. RT-PCR was used here to identify the expression of the selected genes in mice testis.RESULTS AND CONCLUSION: The Affymetrix chip probe of mouse Tpap was graduated higher expression with developmental stages of mouse testis. The scaling hybridization signal intensities of the tested testis on days 4, 9,18, 35, 54, and 6 months of postnatal were 4.4 (Absent expression, A), 12.9 (A), 262.4 (Present expression, P), 1136.7 (P), 1617.5 (P) and 1128 (P),respectively. These results indicated that the expression of mouse Tpap wasn't detected on days 4 and 9, but was detected on days 18, 35, 54, and 6 months of mouse testis in our Affymetrix chip analysis. By combination with the RT-PCR analysis of mouse Tpap, we observed mouse Tpap began to express at the age of day 18 in mouse. Tpap is an age-dependent gene in mouse testis.The expression of Tpap corresponds to the appearance of spermatids of mice and indicates that Tpap may have an important role in male mammalian spermatogenesis.

Objective To detect the mutations of transglutaminase 1 (TGM1) gene in a family with lamellar ichthyosis. Methods The genomic DNA was extracted from the proband and his family members. All the encoding exons and adjacent splice sites of TGM1 gene were amplified by PCR. Mutation scanning was carried out via direct bi-directional DNA sequencing. Also the homology of TGM1 was analyzed. Results In the proband, there was a C504T mutation located at codon 142 (R142C) in exon 3 of TGM1 gene, and a nonsense mutation of C1122T located in exon 7, which caused a premature termination of R348X and a defective polypeptide truncated by 470 amino acids in C-terminus. A heterozygote of C504T mutation was carried by the proband′s father and a heterozygote of C1122T mutation in the proband′s mother. The missense mutation of R142C was found at the conservation region of TGM1 gene. Conclusion The mutations of R142C and R348X in TGM1 gene are present in the patient with lamellar ichthyosis.
