A) GC synthesis in thymocytes is regulated by androgens. Expression of genes encoding steroidogenic enzymes involved in GC synthesis was analyzed by qPCR in thymocytes from castrated mice (n=8) as compared to sham-operated controls (n=8). B) LUC activity stimulated by thymocytes derived from castrated mice vs. sham-operated control mice, as determined by the GC reporter gene coculture assay. C) Expression of genes encoding GC steroidogenic enzymes from castrated + testosterone treated mice (n=8), as compared to vehicle-treated castrated mice (n=8). D) CS secretion by cultured (20 h) thymocytes from castrated+testosterone-treated mice vs. castrated + vehicle-alone-treated mice, as determined by ELISA. E) LUC activity stimulated by thymocytes derived from castrated + testosterone-treated mice vs. castrated+vehicle-alone-treated mice. Control, reporter cells (transfected HEK293 cells) without thymocytes; T, reporter cells plus thymocytes. *P < 0.05; **P < 0.001. NS, not significant.
