Phosphatidylserine Increases IKBKAP Levels in Familial Dysautonomia Cells
Figure 6
Other supplements also increase IKAP mRNA levels in an FD cell line.
(A) Sharp·PS GOLD4508P (Gold), (B) SharpGPC 85F (GPC), or (C) Krill oil+4225F (Krill oil) were added to FDB cells at the indicated concentrations. RNA was extracted 24 hr following the addition of the supplement. Left side: QPCR analysis of the level of exon 20 inclusion isoform (wt). Data were normalized to that of untreated control cells. Right side: RT-PCR analysis of the splicing of IKAP in FDB cells. All splicing products were separated on a 2% agarose gel after RT-PCR reaction using primers to exons 19 and 21. The PCR products were eluted and sequenced. All experiments were repeated independently three times, and the results shown are representative of an average experiment. QPCR experiments were amplified in triplicate; results shown are mean values ± SD.
