Cadmium increased 23 kDa prolactin (PRL) protein expression in anterior pituitary cells in culture.

<p>Anterior pituitary cells were incubated with 10 nM Cd or vehicle (control) for 8 h. Protein expression was measured by western blot. Bars represent mean ± SEM of PRL densitometric values normalized to β-actin and are expressed as percent of control. **P<0.01, Student’s ‘t’ test (N=3).
