Figure 6. Lithium chloride synergizes with gemcitabine in reducing cell viability and tumorigenic potential of PDA cells.

Figure 6

(A) Growth inhibition of PANC-1 and AsPC-1 cells after treatment with 20 mM LiCl, 200 nM gemcitabine and combination of LiCl and gemcitabine. Data (Mean ± SEM) were representative of three independent experiments. P values are indicated by asterisks (relative to control): *P<0.05, **P<0.01, ***P<0.001. (B) Tumorigenic potential of PANC-1 cells as monitored by colony formation after treatment with LiCl, gemcitabine and combination of LiCl and gemcitabine.
