Anti-ageing effects of ubiquinone and ubiquinol in a senescence model of human dermal fibroblasts

Abstract

Coenzyme Q 10 (CoQ 10) is an endogenous lipophilic quinone found in equilibrium between its oxidised (ubiquinone) and reduced (ubiquinol) form, ubiquitous in biological membranes and endowed with antioxidant and bioenergetic properties, both crucial to the ageing process. CoQ 10 biosynthesis decreases with age in different tissues including skin and its biosynthesis can be modulated by 3-hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase inhibitors such as statins. Statin-induced CoQ 10 deprivation has previously been shown to be associated with the development of a senescence phenotype in cultured human dermal fibroblasts (HDF), hence this model was used to further investigate the role of CoQ 10 in skin ageing. The present study aimed to compare the bioavailability of exogenously added CoQ 10, in the form of ubiquinone or ubiquinol, to CoQ 10-deprived HDF, and to determine their efficacy in rescuing the senescent phenotype induced by CoQ 10 deprivation. First, additional senescence markers were implemented to further support the pro-ageing effect of statin-induced CoQ 10 deprivation in HDF. Indeed, numerous senescence-associated secretory phenotype (SASP) markers such as p21, IL-8, CXCL1, and MMP-1 were upregulated, whereas components of the extracellular matrix were downregulated (elastin, collagen type 1). Next, we showed that CoQ 10 supplementation to statin-treated HDF was able to counteract CoQ 10 deprivation and rescued the development of selected senescence/ageing markers in HDF. Ubiquinol resulted more bioavailable than ubiquinone at the same concentration (15 μg/mL) and it significantly improved the cellular oxidative status even within isolated mitochondria highlighting an effective subcellular delivery. Ubiquinol was also more efficient compared to ubiquinone in reverting the expression of the senescent phenotype, quantified in terms of β-galactosidase positivity, p21, collagen type 1, and elastin at the gene and protein expression levels. In conclusion, our results highlight the pivotal role of CoQ 10 for skin vitality and strongly support the use of both forms as a beneficial and effective anti-ageing skin care treatment.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • CoQ10H2 (ubiquinol) is even more efficient than CoQ10 itself in reverting senescence markers expression, both in vitro and in vivo.

    “CoQ10H2 (or ubiquinol), the reduced form of CoQ10, is even more efficient than CoQ10 itself in reverting senescence markers expression, both in vitro and in vivo [66,71].”
  • CoQ10 deficiency has been linked to increased p21 expression, enhanced SASP production and downregulation of collagen type I and elastin.

    “Regarding senescence, CoQ10 deficiency has also been linked to increased p21 expression (a regulator of cell cycle progression), enhanced SASP production and downregulation of some extracellular matrix components (collagen type I and elastin) [66].”
  • Coenzyme Q10, SkQ1, mitoquinone and methylene blue are among mitochondria targeted antioxidants exerting a role in counteracting OS-induced senescence, with CoQ10 being the most studied.

    “Coenzyme Q10 (CoQ10), SkQ1 (a.k.a. visomitin), mitoquinone (MitoQ) and methylene blue are among the mitochondria targeted antioxidants exerting a role in counteracting OS-induced senescence, with CoQ10 being the most studied (Table 1 and Table 2) [57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82].”
  • The outperformance of CoQ10H2 could be at least in part explained by a higher CoQ10H2 bioavailability at the same concentrations, allowing a more efficient subcellular delivery.

    “The reason for this outperformance could be at least in part explained by a higher CoQ10H2 bioavailability at the same concentrations, therefore allowing a more efficient subcellular delivery [66,71].”

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.
