Figure 5From: Challenging the roles of CD44 and lipolysis stimulated lipoprotein receptor in conveying Clostridium perfringens iota toxin cytotoxicity in breast cancerCD44 confers resistance through inhibition of endocytosis. (A) SUM1315mo LSR knockdown and CD44 overexpressing cells were treated with Ia only or iota toxin for 30 min, followed by lysosome imaging. A minimum of fifteen fields was viewed per treatment per experiment. (B) SUM1315mo LSR knockdown and overexpressing and CD44 overexpressing cells were treated with Ia or Ia + Ib for 4 h. Cells were washed, lysates were isolated and analyzed via western blot using an Ib-specific antibody; α-tubulin was used as a loading control. Representative western blot and corresponding intensity were measured via ImageJ.Back to article page
