ABSTRACT:
A transgenic diabetes type II model laboratory animal is disclosed which comprises β-cells expressing a dominant negative form (dnFGFR1c) of FGFR1c. Also disclosed is the use of the Ipf1/pdx1 promoter for controlling expression of FGFR1c; β-cells in which the expression of PC1/3 is down-regulated or absent or which are competent to express a dominant negative form (dnFGFR1c) of FGFR1c; mature β-cells incompetent to express Glut2 or in which the processing of proinsulin is substantially impaired; a method of preventing or treating type II diabetes.
