Humans suffer from high rates of fetal aneuploidy, often arising from the absence of meiotic crossover recombination between homologous chromosomes. Meiotic recombination is initiated by double-strand breaks (DSBs) generated by the SPO11 transesterase. In yeast and worms, at least one buffering mechanism, crossover homeostasis, maintains crossover numbers(More)
The present studies characterize the expression of the alpha 2A, alpha 2B and alpha 2C adrenergic receptor subtypes via in situ hybridization analysis of messenger RNA expression in the adult mouse brain, as well as the pattern of expression of alpha 2A adrenergic receptor messenger RNA at embryonic day E9.5, the earliest time for detection of the messenger(More)
Homology-directed repair (HDR) is a critical pathway for the repair of DNA double-strand breaks (DSBs) in mammalian cells. Efficient HDR is thought to be crucial for maintenance of genomic integrity during organismal development and tumor suppression. However, most mammalian HDR studies have focused on transformed and immortalized cell lines. We report here(More)
The therapeutic mechanism of action underlying many psychopharmacological agents remains poorly understood, due largely to the extreme molecular promiscuity exhibited by these agents with respect to potential central nervous system targets. Agents of the tricyclic chemical class, including both antidepressants and antipsychotics, exhibit a particularly high(More)
Jun dimerization protein 2 (JDP2), a basic leucine zipper transcription factor, is involved in numerous biological and cellular processes such as cancer development and regulation, cell-cycle regulation, skeletal muscle and osteoclast differentiation, progesterone receptor signaling, and antibacterial immunity. Though JDP2 is widely expressed in mammalian(More)
alpha 2-Adrenergic receptors (alpha 2-ARs) respond to norepinephrine and epinephrine to mediate diverse physiological effects. Using in situ hybridization, the expression pattern of the mRNA encoding the three alpha 2-AR subtypes (alpha 2A, alpha 2B, and alpha 2C) was examined in the mouse embryo. The mRNA encoding the three subtypes was first detected at(More)
MicroRNA (miR)-155 is upregulated in breast cancer cells and in sera of patients with breast cancer, but its clinical relevance remains uncertain. The objective of the present effort was to address the transcriptional regulation of miR-155. A bioinformatics analysis of public datasets validated upregulation of miR-155 in tumor cells of patients with breast(More)
The adenosine A1 receptor (A1R) is a key mediator of the neuroprotective effect by endogenous adenosine. Yet targeting this receptor for neuroprotection is challenging due to its broad expression throughout the body. A mechanistic understanding of the regulation of A1R signaling is necessary for the future design of therapeutic agents that can selectively(More)
