Reference genes (RGs) with uniform expression are used for normalization of reverse transcription quantitative PCR (RT-qPCR) data. Their optimization for a specific biological context, e.g. a specific tissue, has been increasingly considered. In this article, we compare RGs identified by expression data meta-analysis restricted to the context tissue, the jejunum of Mus musculus domesticus, i) t...
Genomic DNA of a patient diagnosed with nonobstructive azoospermia and with the history of allogenic bone marrow transplantation from his sister due to chronic myeloid leukemia was isolated from peripheral blood in order to screen Y chromosome microdeletions. 13 short tagged sites belonging to AZF a, b, and c loci were detected with multiplex polymerase chain reaction technique. Bands were dete...
Numeric sex chromosome imbalances, or aneuploidies, are present in several pathological conditions including tumors, abnormal gestations, and clinical syndromes. Here we report a method to identify karyotypic imbalances of the X and Y chromosomes using the polymerase chain reaction (PCR). The polymerase chain reaction was used to quantitatively coamplify the sex chromosome linked genes ZFX and ...
We have confirmed the faster growth of male preimplantation mouse embryos. We have also studied the transcription of Y chromosomal genes postulated to have a role in sex determination, using the highly sensitive technique of reverse-transcription polymerase chain reaction at these early stages. We find that two sex-determining region genes, Sry and Zfy, are transcribed during mouse preimplantat...
Transcription factors (TFs) and their specific interactions with targets are crucial for specifying gene-expression programs. To gain insights into the transcriptional regulatory networks in embryonic stem (ES) cells, we use chromatin immunoprecipitation coupled with ultra-high-throughput DNA sequencing (ChIP-seq) to map the locations of 13 sequence-specific TFs (Nanog, Oct4, STAT3, Smad1, Sox2...
We report a new approach for molecular sex identification of extant Ursinae and Tremarctinae bears. Two Y-specific fragments (SMCY and 318.2) and one X-specific fragment (ZFX) are amplified in a multiplex PCR, yielding a double test for male-specific amplification and an internal positive control. The primers were designed and tested to be bear-specific, thereby minimizing the risk of cross-amp...
