Action against Disease Model PSN357 Preclinical data also suggest a role for glycogen phosphorylase, as exemplified by the results obtained with GPI-688, PSN-357 and CP-368296 in animal models Drug Info
The Effect of Target Knockout, Knockdown or Genetic Variations In comparison to the normal course of the encystment process demonstrated in Fig. 3b and Fig. 4a to d, the glycogen phosphorylase knockdown resulted in a dramatic decrease in the n uMber of mature cysts and an increase in the n uMber of immature precysts (Fig. 3a and 4e to h). In both treated and untreated cultures, trophozoites predominated until 12 h poststimulation, whichwas the stage when the cells started to round up (Fig. 4a and e). In the siRNA-treated cultures, approximately 38% of cells (n = 130) detached and became rounded to form the precysts after approximately 24 h of encystment (Fig. 3a). The n uMber of precysts further increased, so that after 72 h, 70% of the cells with the glycogen phosphorylase knockdown presented the precyst phenotype (Fig. 3a and4h). As shown in Fig. 3b and 4d, at the corresponding stage of the normal encystment process, the precysts were absent and the mature cysts constituted 83% of the population. Some mature cysts were detected in siRNA-treated cultures (Fig. 3a and 4h), but their levels did not exceed 4.5%. [530881]
