PPT1 and prostate cancer: Indeed, it has been reported that both ACSL1 and PPT1 were upregulated in prostate cancer cells.43 STRING analysis showed that ACSL1 does interact with PPT1, and studies have shown that PPT1 glycosylation can affect its ability to form complexes.44 These results do point to a correlation between ACSL1 and PPT1 in prostate cancer that was potentially mediated by glycosylation.
