Results from this study4

No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone4

In this study, Humanin was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Humanin.

  1. 01LabNot a test of Humanin aloneIn vitro (cell-free)Mechanism

    Humanin changed into a beta-sheet structure at neutral pH with negatively charged DOPG liposomes, but not with neutral DOPC liposomes.

    In plain wordsIn lab tests, humanin folded into a sheet-like shape with negatively charged fat bubbles but not with neutral ones.

    Summary
    Humanin underwent a large structure change into a typical beta-sheet structure at neutral pH in the presence liposome made of a negatively charged 1,2-dioleoyl-sn-glycero-3-phosphoglycerol (DOPG), but not an electrically neutral 1,2-dioleoyl-sn-glycero-3-phosphatidylcholine (DOPC).

    Summary · context
    Here we have examined the structure in lipid environments, i.e., in the presence of liposome by circular dichroism.

    In this study, Humanin was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Humanin.

  2. 02LabNot a test of Humanin aloneIn vitro (cell-free)Mechanism

    NaCl had no effect on the humanin structure in neutral solution or in the presence of DOPC liposome.

    In plain wordsIn lab tests, adding salt did not change the shape of humanin in plain solution or with neutral fat bubbles.

  3. 03LabNot a test of Humanin aloneIn vitro (cell-free)Mechanism

    Increasing temperature changed the humanin structure through aggregation.

    In plain wordsIn lab tests, raising the temperature changed the shape of humanin because it clumped together.

  4. 04LabNot a test of Humanin aloneIn vitro (cell-free)Mechanism

    Humanin had a relatively stable structure against temperature in the presence of DOPG liposome, independent of NaCl.

    In plain wordsIn lab tests, humanin kept a fairly stable shape when heated in the presence of negatively charged fat bubbles.

    Summary
    On the other hand, the effects of temperature on the Humanin structure showed that it has a relatively stable structure in the presence of DOPG liposome independent of the presence of NaCl.
