Abstract

CONTEXT: Chronic sex steroid deficiency has effects on adipose fatty acid (FA) storage mechanisms and fat oxidation, but the chronology of events are not well understood. OBJECTIVE: The objective of the study was to examine the acute effects of female sex steroid suppression on cellular mechanisms affecting abdominal and femoral subcutaneous adipose tissue FA storage. DESIGN: This study had a randomized, longitudinal, parallel study design. SETTING: The study was conducted at the Mayo Clinic Clinical Research Unit. PARTICIPANTS: Thirty-eight nonsmoking premenopausal women aged 18-50 years participated in the study. INTERVENTION: The intervention included randomization to receive one of the following: 1) no treatment (control), 2) 3.75 mg of Lupron, or 3) 3.75 mg of Lupron and estrogen, but not progesterone, replacement for 49 days, resulting in at least 4 weeks of sex steroid suppression. MAIN OUTCOME MEASURES: Body composition, fat cell size, postprandial chylomicron and nonchylomicron triglyceride concentrations, adipose tissue meal FA storage, direct free fatty acid storage, lipoprotein lipase, acyl CoA synthetase, and diacylglycerol acyltransferase activities, and CD36 content were measured. RESULTS: Compared with the control group, the fed state femoral lipoprotein lipase activity was reduced in women taking Lupron and those taking Lupron and estrogen replacement. In addition, we observed significantly greater postprandial chylomicronemia in the Lupron group than in the other two groups. There were no differences in overall fat storage and oxidation. Depending on the mode of data expression (per unit lipid vs per 1000 adipocytes), there were modest changes in acyl CoA synthetase, diacylglycerol acyltransferase, and CD36 in response to acute sex hormone suppression. CONCLUSIONS: Our results suggest estrogen and progesterone may have different effects on the regulation of FA metabolism and that acute sex steroid deficiency in women does not alter fat storage and oxidation.

  • With chronic (at least 6 months) or acute (at least 4 weeks) testosterone suppression, the proportion of meal fat stored in lower body subcutaneous adipose tissue is greater than in males with normal testosterone concentrations.

    “However, with both chronic (at least 6 months) (20) and acute (at least 4 weeks) (115) testosterone suppression, the proportion of meal fat stored in lower body subcutaneous adipose tissue is greater than in those with normal testosterone concentrations.”

    From Sex differences in the metabolism of glucose and fatty acids by adipose tissue and skeletal muscle in humans (2025) · cites this paper as [115]

    The citation (115) is attached to the acute-suppression part of the sentence. The Discussion (page unavailable) explicitly reports no effect of acute sex-hormone suppression on regional meal fatty-acid storage. The study examined estrogen and progesterone suppression in premenopausal women, not testosterone suppression in males. (LLM, conf=0.85)

    Checked by a reasoning model — may be wrong.

  • Neither 7 days nor 4 weeks of gonadal hormone suppression in young men using GnRH agonists changes postprandial fat oxidation or meal fat oxidation following a mixed meal.

    “However, neither 7 days (117) nor 4 weeks (115) of gonadal hormone suppression in young men using GnRH agonists changes postprandial fat oxidation (indirect calorimetry) or meal fat oxidation (isotopic tracers) following consumption of a mixed meal.”

    From Sex differences in the metabolism of glucose and fatty acids by adipose tissue and skeletal muscle in humans (2025) · cites this paper as [115]

    The 'Substrate and meal FA oxidation' section reports no differences in postprandial total fatty acid oxidation or meal fatty acid oxidation after at least four weeks of suppression. But the study enrolled premenopausal women, not young men. The seven-day result is attached to a different citation in the citing sentence and is not assessed here; page numbers are not available in the supplied passages. (LLM, conf=0.89)

    Experimental — accuracy not yet measured
  • The proportion of meal fat stored in upper body subcutaneous adipose tissue is greater than in lower body subcutaneous adipose tissue regardless of whether males have normal, chronically low, or acutely reduced testosterone status.

    “The proportion of meal fat stored in upper body subcutaneous adipose tissue is greater than in lower body subcutaneous adipose tissue regardless of whether males have normal (20, 115), chronically low (20), or acutely reduced (115) testosterone status.”

    From Sex differences in the metabolism of glucose and fatty acids by adipose tissue and skeletal muscle in humans (2025) · cites this paper as [115]

    The Regional meal and direct FA storage section reports a greater proportion of meal fat stored in upper- than lower-body subcutaneous tissue in two treatment groups of women; the control group showed only a trend. This supports the regional comparison, but the study does not establish it in men with normal, chronically low, or acutely reduced testosterone. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • The increase in meal fat storage in acutely hypogonadal males was associated with greater LPL and ACS activity in the femoral region.

    “This increase in meal fat storage was associated with greater LPL and ACS activity in the femoral region of acutely hypogonadal males, indicating a role of these two enzymes in the storage of meal FA in the femoral subcutaneous adipose tissue depot (115).”

    From Sex differences in the metabolism of glucose and fatty acids by adipose tissue and skeletal muscle in humans (2025) · cites this paper as [115]

    The LPL activity and meal FA storage section reports an association between femoral LPL activity and meal-fat storage when all groups of women were combined, but not a significant femoral association within the acutely hypogonadal group. The Discussion says acute hormone suppression did not increase regional meal-fat storage; its femoral ACS association concerns direct FFA storage, not meal-fat storage. The study examined women, not males. (LLM, conf=0.88)

  • LPL and ACS activity may play a role in storage of meal FA in the femoral subcutaneous adipose tissue depot.

    “This increase in meal fat storage was associated with greater LPL and ACS activity in the femoral region of acutely hypogonadal males, indicating a role of these two enzymes in the storage of meal FA in the femoral subcutaneous adipose tissue depot (115).”

    From Sex differences in the metabolism of glucose and fatty acids by adipose tissue and skeletal muscle in humans (2025) · cites this paper as [115]

    The “LPL activity and meal FA storage” section reports a correlation between fed LPL activity and femoral meal-fatty-acid storage across the combined groups, supporting a possible role for LPL. But this study examined women, not acutely hypogonadal males; its ACS association concerned direct FFA storage rather than meal-fatty-acid storage. The Discussion also reports no effect of acute hormone suppression on regional meal-fatty-acid storage, contrary to the cited sentence’s claimed increase. (LLM, conf=0.88)

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.
