| Abstract: | We report the silencing of CA1 mRNA in PC3 and MDA cells. The levels of mRNA coding CA1 protein in the knock‐down mRNA (CA1 siRNA) cells have been measured by RT‐PCR and were approximately 5% (PC3) and 20% (MDA‐MB‐231), respectively, of the level of control (Mock siRNA) used during silencing. In PC3 and MDA‐MB‐231 cells, the mRNAs for COL1A1 and COL4A4 were up‐regulated. The mRNAs for CTHRC1, LAMC2, and WNT7B were not changed when compared to the control. The morphology of the cells during the treatments remained the same. On the Western blots, the lysate from the silenced cells showed lower levels of CA I as well. |
