The LDLR mRNA exhibits a cell- and tissue-specific half-life, ranging from about 2 hours in human HepG2 cells to about 3 hours in Hepa 1-6 mouse hepatocytes.
“The LDLR mRNA exhibits a cell-and tissue specific half-life, ranging from ~2 h in human HepG2 cells and ~3 h in Hepa 1-6 mouse hepatocytes, indicating a potential for rapid modulation of LDLR protein production [21,22].”
From The low-density lipoprotein receptor: Emerging post-transcriptional regulatory mechanisms (2025) · cites this paper as [21]
The Results section reports an approximately 2-hour LDLR mRNA half-life in HepG2 cells under several AKT-inhibitor treatments. The paper does not report a 3-hour half-life in Hepa 1-6 mouse hepatocytes; its 3-hour result concerns inhibitor-treated HepG2 cells. Page numbers are unavailable in our copy. (LLM, conf=0.88)
Experimental — accuracy not yet measuredDifferent research groups have identified more than ten different compounds that enhance LDLR mRNA stability and subsequently increase LDLR protein levels, although the mechanisms and specificity are not fully understood.
“Adding to the complexity of LDLR mRNA regulation, different research groups have identified more than ten different compounds that enhance LDLR mRNA stability and subsequently increase LDLR protein levels, although the mechanism(s) behind these effects and how specific they are is not yet fully understood [19,21,24,32,[35][36][37][38][39][40][41].”

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.
