Figure 1From: Activin B can signal through both ALK4 and ALK7 in gonadotrope cellsALK7 is expressed in LβT2 cells. ALK7 mRNA expression was analyzed by RT-PCR in adult mouse pituitary and brain, and in LβT2 cell RNA. RT+ and RT- indicate that reverse transcriptase enzyme was included or omitted, respectively, during the cDNA synthesis step. The H2O sample confirmed that none of the reagents were contaminated.Back to article page
