Figure 4. mTOR inhibition does not alter the global protein expression of folate transporter isoforms in total PHT cell lysates.

Representative western blots are shown for (a) PCFT (b) FR-α and (c) RFC in cell lysates of PHT cells transfected with scramble, raptor or rictor siRNA. Equal loading was performed. The histogram (d) summarizes the western blot data. Values are means + SEM, n = 3.
