MMP-2 expression and activity in
Mpv17 transfectants. (A) Northern analysis of
Mpv17-negative LUSVX cells and two different clones of
LUSVX cells, stably transfected with different Mpv17 expression
constructs (LuMpv9, LuMpv15). The two Mpv17 transcripts can be detected
at 3.5 kb and 4.5 kb, respectively; 2.7 kb is the size of the MMP-2
transcript and 1.4 kb is the size of the GAPDH transcript. (B)
Substrate gel analysis (Zymogram) of LUSVX, LU-Mpv9, and LU-Mpv15
cells.
