Abstract

One of the key challenges in lipidomics is to quantify lipidomes of interest, as it is practically impossible to collect all authentic materials covering the targeted lipidomes. For diverse ceramides (CER) in human stratum corneum (SC) that play important physicochemical roles in the skin, we developed a novel method for quantification of the overall CER species by improving our previously reported profiling technique using normal-phase liquid chromatography-electrospray ionization-mass spectrometry (NPLC-ESI-MS). The use of simultaneous selected ion monitoring measurement of as many as 182 kinds of molecular-related ions enables the highly sensitive detection of the overall CER species, as they can be analyzed in only one SC-stripped tape as small as 5 mm x 10 mm. To comprehensively quantify CERs, including those not available as authentic species, we designed a procedure to estimate their levels using relative responses of representative authentic species covering the species targeted, considering the systematic error based on intra-/inter-day analyses. The CER levels obtained by this method were comparable to those determined by conventional thin-layer chromatography (TLC), which guarantees the validity of this method. This method opens lipidomics approaches for CERs in the SC.

  • Earlier studies have reported that ceramides with odd-chain FAs exist at high levels in the SC.

    “Earlier studies have reported that ceramides with oddchain FAs exist at high levels in the SC (Fig. 3F, supplemental Table S3) (7,55).”

    From Comparative profiling and comprehensive quantification of stratum corneum ceramides in humans and mice by LC/MS/MS (2020) · cites this paper as [55]

    The Methods passage lists an odd-chain ceramide, CER[N(17)S(18)], as an internal standard, not as a ceramide found at high levels in stratum corneum. Searches for odd-chain fatty acids and their abundance found no passage in our copy reporting the claimed high levels; the paper discusses quantifying ceramide species generally. (LLM, conf=0.72)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
