- Schematic representations of the SF reporter constructs (left panel). The relative luciferase activity (Fluc/Rluc) was measured as described previously (right panel). Data are presented as means (n = 4). Error bars represent ± s.d. In the negative control construct (NC), a 159-bp fragment of a non-promoting sequence taken within the gfp gene was cloned upstream the −356 to fill the space between −515 and −356.
- Genomatix in silico analysis of the region from −515 to −356 upstream of the transcription start site (TSS). Boxes indicate transcription factor-binding sites. Grey boxes indicate transcription factors known to be expressed in ovarian somatic stem (OSS) cells (modEncode data).
- Schematic representation of firefly reporters carrying deletions of each predicted transcription factor-binding site. The Fluc/Rluc activity was measured as described previously (right panel). Data are presented as means (n = 4). Error bars represent ± s.d.
