Biological target:
Demeclocycline is a tetracycline antibiotic used to treat a wide variety of susceptible bacterial infections.
In vitro activity:
Because earlier results suggest that demeclocycline alone reduced BTIC growth, it was sought to investigate its direct role further. BTICs were subjected to different concentrations of demeclocycline and found that 5 and 10 μM decreased sphere formation and cell number (Figures 3A,B). Notably, demeclocycline at 10 μM concentration had selective efficacy on BTICs as it was without obvious toxicity to non-transformed CNS cells such as microtubule associated protein-2 (MAP-2) labeled neurons (Figures 3D,E). As the above experiments involved the treatment of freshly dissociated BTIC lines with demeclocycline to determine whether the medication reduced sphere formation and other indices of BTIC growth, it was next addressed whether demeclocycline affected BTIC spheres that were already well-formed. It was found that when demeclocycline (10 μM) was added to growing spheres 3 days after their formation from singly dissociated cells, the drug still reduced the further growth of spheres of the BT025 and BT048 lines (Figures 3F–H). Overall, the results suggest that demeclocycline can control BTIC growth in two ways: using monocytes as an intermediary, and directly by affecting the proliferation and sphere-forming capacity of BTICs.

In vivo activity:
Immunoblot analysis revealed a significant 75% reduction in AQP2 (aquaporin) abundance in the inner medulla of rats treated with demeclocycline compared with control rats (Fig. 10A). However, demeclocycline treatment led to significant 2.5- and 2.0-fold increases in AQP2 abundance in the outer medulla and cortex, respectively (Fig. 10, B and C). In kidney sections from control rats, immunostaining with a total AQP2 antibody demonstrated clear labeling of the apical and basolateral plasma membrane of inner medullary collecting duct cells (Fig. 11, A and C). In comparison, in kidney sections from demeclocycline-treated rats, AQP2 labeling intensity was clearly reduced (Fig. 11B). In addition, the cellular distribution of AQP2 was different in demeclocycline-treated rats; AQP2 was less prominent at the apical and basolateral plasma membrane, and greater numbers of AQP2-positive intracellular vesicles were observed (Fig. 11D). Immunohistochemistry using an antibody against pS256 AQP2 showed a large decrease in labeling intensity in demeclocycline-treated rats compared with control rats (Fig. 11, E and F, for the inner medulla). Additionally, immunoblot analysis revealed that AC5/6 abundance was 50% reduced in the inner medulla of demeclocycline-treated rats (Fig. 12A).
