Action against Disease ModelSotrastaurin acetateTotal protein kinase C (PKC) activity and the expression of 9 isoforms were determined in the estrogen receptor (ER) positive MCF-7 h uMan breast cancer cell line, this line transfected to overexpress either PKC-Ø¢ or erbB2, and in 3 ER negative breast cancer cell lines.[18]
The Effect of Target Knockout, Knockdown or Genetic VariationsThe Prkca(-/-) mice showed no signs of retinal degeneration up to 12 months of age, but ERG measurements indicated a decelerated increase in the ascending limb of the scotopic (rod-sensitive) b-wave as well as a delayed return to baseline. These results suggest that PKC¦Į is an important modulator that affects bipolar cell signal transduction and termination. Confocal microscopy of retinal sections showed that PKC¦Į co-localized with calbindin, which indicates a PKC¦Į localization in close proximity to the horizontal cell terminals. In addition, the implicit time of the ERG c-alpha originating from the retinal pigment epitheli uM (RPE) and the recovery of photoreceptors from bleaching conditions were substantially faster in the knockout mice than in the wild-type control animals”£hese results suggest that PKC¦Į is a modulator of rod-bipolar cell function by accelerating glutamate-driven signal transduction and termination[19]
