Figure 1. Lhx3 mRNA and protein are expressed in mouse pituitary Pit-1/Triple but not Pit-1/0 cells.
(A) Lhx3a or Lhx3b mRNA was amplified by RT-PCR in Pit-1/0 and Pit-0/Triple cells. Beta actin primers were used in a positive control to test cDNA integrity. (B) Protein levels of LHX3 were determined by western blotting of whole cell protein extracts of Pit-1/0 and Pit-1/Triple cells. Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) antibodies were used as positive controls. Each experiment was performed three times with similar results.
