FIGURE 3:

Insulin signaling regulates GSC centrosome orientation. (a) Centrosome misorientation frequency upon overexpression of a dominant-negative (K1409A) or a constitutively active form (Del, R418P, or A1325D) of InR using nos-gal4. n > 300/data point. Siblings from the same cross without the nos-gal4 driver served as controls. p values (Student's t test, two-tailed) are provided on each column compared with its control. Statistically significant values (p < 0.01) are highlighted with asterisks. (b) Akt functions downstream of InR in regulating centrosome orientation. n > 300/data point. (c) Local expression of dilp1, 2, 3, 5, and 6 in the testis reduces centrosome misorientation in poor media. Each dilp was expressed in the testis (nos-gal4>UAS-dilp).
