Sphingolipids including sphingosine‐1‐phosphate and ceramide participate in numerous
cell programs through signaling mechanisms. This class of lipids has important functions in
stress responses; however, determining which sphingolipid mediates specific events has
remained encumbered by the numerous metabolic interconnections of sphingolipids, such
that modulating a specific lipid of interest through manipulating metabolic enzymes causes
'ripple effects', which change levels of many other lipids. Here, we develop a method of …

Sphingolipids including sphingosine‐1‐phosphate and ceramide participate in numerous cell programs through signaling mechanisms. This class of lipids has important functions in stress responses; however, determining which sphingolipid mediates specific events has remained encumbered by the numerous metabolic interconnections of sphingolipids, such that modulating a specific lipid of interest through manipulating metabolic enzymes causes ‘ripple effects’, which change levels of many other lipids. Here, we develop a method of integrative analysis for genomic, transcriptomic, and lipidomic data to address this previously intractable problem. This method revealed a specific signaling role for phytosphingosine‐1‐phosphate, a lipid with no previously defined specific function in yeast, in regulating genes required for mitochondrial respiration through the HAP complex transcription factor. This approach could be applied to extract meaningful biological information from a similar experimental design that produces multiple sets of high‐throughput data.
