Abstract

Objective Substrates of placental efflux transporters could compete for a single transporter, which could result in an increase in the transfer of each substrate to the fetal circulation. Our aim was to determine the role of placental transporters in the biodisposition of oral hypoglycemic drugs that could be used as monotherapy or in combination therapy for gestational diabetes. Study design Inside-out brush border membrane vesicles from term placentas were used to determine the efflux of glyburide, rosiglitazone, and metformin by P-glycoprotein, breast cancer resistance protein, and multidrug resistance protein. Results Glyburide was transported by multidrug resistance protein (43 +/- 4%); breast cancer resistance protein (25 +/- 5%); and P-glycoprotein (9 +/- 5%). Rosiglitazone was transported predominantly by P-glycoprotein (71 +/- 26%). Metformin was transported by P-glycoprotein (58 +/- 20%) and breast cancer resistance protein (25 +/- 14%). Conclusion Multiple placental transporters contribute to efflux of glyburide, rosiglitazone, and metformin. Administration of drug combinations could lead to their competition for efflux transporters.

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

  • The actions of PPARγ in the brain of murine models of AD have been controversial, largely due to poor penetrance of its agonists into the brain and active P-glycoprotein-mediated efflux mechanisms.

    “The actions of PPARγ in the brain of murine models of AD have been controversial, largely due to the poor penetrance of its agonists into the brain and active P-glycoprotein-mediated efflux mechanisms (Maeshiba et al., 1997; Hemauer et al., 2010).”

    From Mechanisms Underlying the Rapid Peroxisome Proliferator-Activated Receptor-γ-Mediated Amyloid Clearance and Reversal of Cognitive Deficits in a Murine Model of Alzheimer's Disease (2012) · cites this paper as Hemauer et al., 2010

    The COMMENT section (page not available) says P-glycoprotein transports rosiglitazone from brain to blood, supporting an efflux mechanism for that agonist. The paper does not establish poor brain penetration of PPARγ agonists generally or link that mechanism to controversy about PPARγ actions in murine Alzheimer’s disease models. (LLM, conf=0.86)

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.
