- Please help me with these questions, more than one answer may be correct for each:The above figures are showing the results BMAL1 gene knockout on the GFR and blood aldosterone in a mouse model over a 24-hour period (12h light, 12h dark). ZT stands for Zeitgeber times, which is simply the number of hours since the beginning of the light period in the day. GFR (dashed lines) was tested for a match to the modeled circadian cycle (solid line in top figure), and a p-value < 0.05 indicates a significant match (both control and knockouts were tested against the same modeled circadian cycle). Significant differences between control (black) and knockout (red) mice blood aldosterone are marked with stars. 1) Genes/proteins that one could knockout that would likely have a similar effect include: H ATPase NA/K ATPase PER Anion exchanger Cryptochrome 2) According to the figures above,…Figure 5: MCF-7 cells were incubated for 24 h with the drug dilution buffer (control) or various concentrations of indibulin.
