– Distribution of BAC clones
https://brc.riken.jp/dna/GRP0055e#EXR0107e
RIKEN BRC DNA Bank distributes the following Bacterial Artificial Chromosomes (BAC) clones; Mouse (C57BL/6N and MSM/Ms strains), Rat (F344/Stm and LE/Stm strains), Japanese macaque (M. fuscacta), and Drosophila flies (5 species, including D. melanogaster). These BAC clones can be searched by a gene symbols as a key word, and the position of the clone on the genome region can be visually confirmed.
We look forward to receiving your order.
BAC clones are used to construct gene knock out (KO) vectors and reporter genes having fluorescent proteins and LacZ to develop KO and transgenic animals. The BAC clones are also used for cloning the transcriptional regulatory region of genes. One of successful use of BAC clone is described in the following section.
– Glucocorticoid up-regulates PD-1 on T cells
T cell activation is known to be suppressed by an immunosuppressant Glucocorticoid (GC) and by inductively expressed PD-1.
Maeda, N. et al. found the enhancement of PD-1 expression by GC during their study of the effect of immunosuppressants on PD-1 expression. Furthermore, they found that the up-regulation of PD-1 was caused by the transcriptional activation of PD-1 via the GC response element on the transcription regulatory region located upstream of the PD-1 gene.
In their study, the genomic fragment of the transcriptional regulatory region of PD-1 used for this analysis was amplified by PCR from the B6N BAC clone B6Ng01-240G08 provided by us.
