Nodal Signaling Is Required For Closure Of The Anterior Neural Tube In Zebrafish, Allisan Aquilina-Beck, Kristine Ilagan, Qin Liu, Jennifer O. Liang
Biology Faculty Research
Background: Nodals are secreted signaling proteins with many roles in vertebrate development. Here, we identify a new role for Nodal signaling in regulating closure of the rostral neural tube of zebrafish.
The Organizational Effects Of Oxytocin On The Central Expression Of Estrogen Receptor Alpha And Oxytocin In Adulthood, Kristin M. Kramer, Shigeto Yoshida, Eros Papademetriou, Bruce S. Cushing
The Organizational Effects Of Oxytocin On The Central Expression Of Estrogen Receptor Alpha And Oxytocin In Adulthood, Kristin M. Kramer, Shigeto Yoshida, Eros Papademetriou, Bruce S. Cushing
Biology Faculty Research
Background: Previous studies have demonstrated that neonatal manipulation of oxytocin (OT) has effects on the expression of estrogen receptor alpha (ER alpha) and the central production of oxytocin observed in juveniles ( at weaning, 21 days of age). The goal of this study was to determine whether the effects of neonatal manipulation of OT last into adulthood, and if the effects differ from those observed during the early postnatal period. On the first day of life, prairie voles ( Microtus ochrogaster) received one of three doses of OT (High, 3 mu g; Med, 0.3 mu g; Low, 0.03 mu g), …
Genomic And Expression Analysis Of Multiple Sry Loci From A Single Rattus Norvegicus Y Chromosome, Monte E. Turner, Carey Martin, Almir S. Martins, Jeffrey Dunmire, Joel Farkas, Daniel L. Ely, Amy Milsted
Genomic And Expression Analysis Of Multiple Sry Loci From A Single Rattus Norvegicus Y Chromosome, Monte E. Turner, Carey Martin, Almir S. Martins, Jeffrey Dunmire, Joel Farkas, Daniel L. Ely, Amy Milsted

Background: Sry is a gene known to be essential for testis determination but is also transcribed in adult male tissues. The laboratory rat, Rattus norvegicus, has multiple Y chromosome copies of Sry while most mammals have only a single copy. DNA sequence comparisons with other rodents with multiple Sry copies are inconsistent in divergence patterns and functionality of the multiple copies. To address hypotheses of divergence, gene conversion and functional constraints, we sequenced Sry loci from a single R. norvegicus Y chromosome from the Spontaneously Hypertensive Rat strain (SHR) and analyzed DNA sequences for homology among copies. Next, to determine …

As part of the Episodic Events Great Lakes Experiment, we sampled total suspended matter (TSM), light climate, nutrients, and plankton along cross-margin transects in southern Lake Michigan during February, March, and April 1998-2000 to capture conditions before, during, and after the occurrence of storm-driven recurrent coastal sediment plumes to define the anatomy of the resuspension events and get insights into their interactions with nutrients and plankton. Variability in timing and strength of winter storms among years led to different timing, intensity, and extent of plumes among years. TSM concentrations in the core of plumes varied between 15 and 30 mg …
