From: Mating alters gene expression patterns in Drosophila melanogaster male heads
fit expression in the fat body is increased after courtship culminating in mating. In situ hybridization was performed on cryosectioned male heads and confirmed that fit transcript levels were up regulated in adipose tissue (arrows) of mated males (panel B) compared to control males (panel A) as indicted by increased intensity of purple staining in mated male fat body. Insets in panels A and B show magnified views of head fat. Qualitative assessment of signal intensity in both treatment groups indicates that fit expression increased in mated male heads (panel C).
