Figure Lengend Snippet: Knockdown of FLNB promotes proliferation and inhibits apoptosis of HeLa cells. (A) Relative mRNA expression of FLNB in HeLa cells after it was knocked down using FLNB -specific shRNA was determined by reverse transcription-qPCR. shFLNB_1 and shFLNB_2 indicate two biological repeats of HeLa cells transfected with FLNB-specific shRNA. Ctrl_1 and Ctrl_2 indicate two biological repeats of HeLa cells transfected with empty vector as controls. (B) Cell proliferation of shFLNB was measured by an MTT assay in HeLa cells. Cell apoptosis of cells transfected with shFLNB was measured by (C) flow cytometry and (D) subsequent analysis by a 7-ADD and Annexin V assay. *P<0.05 and **P<0.01 vs. respective Ctrl.

Figure Lengend Snippet: MIM-1 and MIM-5 lowered the cellular viability/proliferative potential in a model of starved HPV-positive cervical cancer cells. Cell viability/proliferative potential of HeLa cells was assessed via AlamarBlue reagent under the experimental conditions presented in (see ) when treated with the vehicle (Veh.), MIM-1 or MIM-5.
