CELL CYCLE CONTROLLING COMPOSITIONS AND METHODS OF USING SAME

摘要

A method of controlling cell cycle progression including into a cell to be controlled during the interphase portion of the cell cycle regulating composition. The composition is selected from the grou p consisting of a protein and a fragment of the pro-tein to alter the cell cycle progression of the cell while maintaining t he viability of the cell. The protein fragments have been found to have the unexpected and surprising characteristic of being soluble in low concentrations of glycerol, thereby enhancing their value in pharmaceutical applications.
