Regulation of gene transcription by the progesterone receptor (PR) in cooperation with coactivator/corepressor complexes coordinates crucial processes in female reproduction. To investigate functional relationships between PR and steroid receptor coactivators (SRCs) in distinct cell types of uterine tissue during gene transcription, we generated a new transgenic mouse model utilizing a Progeste...
Medaka genomic BAC clones, which contained two types of medaka hemopexin-like protein gene (Wap65), mWap65-1 and mWap65-2, were screened and their genomic sequences were determined by the shotgun strategy. The exon-intron organizations were highly conserved between both mWap65s and human hemopexin genes. The 5'-flanking regions of mWap65-1 and mWap65-2 contained various putative transcription f...
Adenosine A2A receptors (A2ARs) in the nucleus accumbens (Acb) have been demonstrated to play an important role in the arousal effect of adenosine receptor antagonist caffeine, and may be involved in physiological sleep. To better understand the functions of these receptors in sleep, projections of A2AR neurons were mapped utilizing adeno-associated virus (AAV) encoding humanized Renilla green ...
Viral vectors are engineered virus variants able to deliver nonviral genetic information into cells, usually by the same routes as the parental viruses. For several virus families, replication-competent vectors carrying reporter genes have become invaluable tools for easy and quantitative monitoring of replication and infection, and thus also for identifying antivirals and virus susceptible cel...
The neuropeptide galanin has diverse roles in the central and peripheral nervous systems, by activating the G protein-coupled receptors Gal1, Gal2 and the less studied Gal3 (GalR1-3 gene products). There is a wealth of data on expression of Gal1-3 at the mRNA level, but not at the protein level due to the lack of specificity of currently available antibodies. Here we report the generation of kn...
Embryonic stem cells (ES) are pluripotent and may therefore serve as a source for the generation of specific cell types required for future therapies based on cell replacement. The isolation of defined cell populations from a certain lineage or tissue is a prerequisite for the analysis of the potential of such ES-derived cells in animal transplantation studies. Here, using the Cre/loxP system, ...
یکی از چالشهای فرایند انتقال ژن در ماهیان، توسعة سیستمهایی برای انتقال کارآمد DNA است. در این پژوهش از پروتئینهای باکتریایی برای هدفمندسازی انتقال ژن به تیرة سلولی ماهی زبرا استفاده شده است. اگروباکتریوم با نام علمی Agrobacterium tumefaciens قادر به انتقال کارآمد DNA خود به صورت یک مجموعه DNA-Protein به سلولهای گیاهی است. پروتئینهای اگروباکتریوم VirD2 و VirE2 در این فرایند نقش مهمی را ایفا...
