Several genome-wide association studies have implicated the transcription factor E-twenty- six version 5 (Etv5) in the regulation of body mass index. Further substantiating the role of Etv5 in feeding behavior are the findings that targeted disruption of Etv5 in mice leads to decreased body weight gain and that expression of Etv5 is decreased in the ventral tegmental area and substantia nigra pars compacta (VTA/SNpc) after food restriction. As Etv5 has been suggested to influence dopaminergic neurotransmission by driving the expression of genes that are responsible for the synthesis and release of dopamine, we investigated if expression levels of Etv5 are dependent on nutritional state and subsequently influence the expression levels of tyrosine hydroxylase. While it was shown that Etv5 expression in the VTA/SNpc increases after central administration of leptin and that Etv5 was able to drive expression of tyrosine hydroxylase in vitro, AAV-mediated gene transfer of Etv5 into the VTA/SNpc of rats did not alter expression of tyrosine hydroxylase in vivo. Moreover, AAV-mediated gene transfer of Etv5 in the VTA/SNpc did not affect measures of energy balance or performances in a progressive ratio schedule. Thus, these data do not support a role for increased expression of Etv5 in the VTA/SNpc in the regulation of feeding behavior.

In the face of increasing and diversifying graduate application numbers, evidencebased selective admissions have become a pressing issue. By conducting multilevel regression analyses on institutional admissions data from a Dutch university, this study aims to determine the predictive value of undergraduate academic indicators for graduate study success on research masters' programs in the life sciences. The results imply that in addition to undergraduate grade point average, undergraduate thesis grade is a valid predictor of graduate grade point average. To a small extent, the examined undergraduate academic indicators also predict graduate degree completion and time to degree. The results from this study can be used by admissions committees for evaluating and improving their current practices of graduate selective admissions.
