TranscriptomicsIncomplete X-inactivation initiated by a hypomorphic Xist allele in the mouse
Mammals have evolved a mechanism to compensate for the difference in the number of X chromosome genes between XX females and XY males by inactivating one of the two X chromosomes in females. This X chromosome inactivation phenomenon is triggered by Xist gene, which is essential for X-inactivation to...

TranscriptomicsImpeding Xist expression from the active X chromosome improves mouse somatic cell cloning
Cloning mammals by somatic cell nuclear transfer (SCNT) is highly inefficient because of aberrant genomic reprogramming. In addition to random reprogramming errors, we hypothesized the presence of specific errors as evidenced by common anomalies among clones. We found that Xist, which normally inact...

TranscriptomicsAnalysis of small RNAs in piRNA pathway mutant mouse testes
Piwi-interacting RNAs are 25-32 nt small RNAs bound to Piwi proteins. To know the steps where factors involved in the piRNA biogenesis (MILI, MIWI2, ZUC (MitoPLD), MVH) work, we sequenced small RNAs from mutant mouse testes and analyzed piRNAs. Examination of small RNAs in testes of mutant mouse
