Sulfated polysaccharide of Sepiella maindroni ink targets Akt and overcomes resistance to the FGFR inhibitor AZD4547 in bladder cancer

Figure 5. Dual treatment with SIP-SII and AZD4547 potentiates the inhibition of Akt and downstream effectors. (A) Western blot analysis of RT112 and JMSU1 cells exposed (24 h) to DMSO, 5.0 μM SIP-SII, 100 nM AZD4547, or SIP-SII combined with AZD4547. (B) Western blot analysis of RT112 and JMSU1 cells treated for 24 h with DMSO, 5.0 μM SIP-SII, 100 nM AZD4547, or SIP-SII combined with AZD4547 in the presence of 0.5 μM BKM120.
