Expression Pattern :

Pattern  This reporter revealed a striking dimorphism across all stages: while hermaphrodite expression is low and restricted, males exhibit higher and broader neuronal GFP expression throughout development. We used "NeuroPAL" (Neuronal Polychromatic Atlas of Landmarks) to identify cell types using color barcodes. We found that in young adult hermaphrodites, INS-39 was specifically expressed in two sets of neurons, AFD and ASK. In contrast, in males, INS-39 was expressed in five sets of neurons, AFD, ASK, ASJ, ASE, and AWC, all of which are ciliated sensory neurons with thermosensory, chemosensory, olfactory, electrosensory, and photosensory functions. Using fluorescent dye staining of head ciliated sensory cells and an AFD marker, we validated the higher GFP intensity in ASK, ASJ, and AFD neurons in adult males compared to hermaphrodites. Taken together, the robust expression in sensory neurons in males from the earliest stages of development suggests INS-39 is under tight and sex-specific regulatory control.
