Abstract

Minocycline is protective in models of transient middle cerebral artery occlusion (MCAO). We studied whether minocycline and doxycycline, another tetracycline derivative, provide protection in permanent MCAO. Because minocycline inhibits matrix metalloprotease-9 (MMP-9), we also compared minocycline's protective effect in wild type (wt) and MMP-9 knock-out (ko) mice. Wt FVB/N, Balb/C, and two lines of MMP-9 ko and their wt C57Bl/6 control mice were subjected to 24- or 72-hour permanent MCAO. Drug administration was started either 12 hours before or 2 hours after the onset of MCAO. Infarct size was determined by triphenyltetrazolium staining or T2-weighted MRI. Zymography was used to study the expression of MMPs. In wt strains, tetracycline treatments started before MCAO reduced the infarct size by 25% to 50%, whereas the treatment started after MCAO was not protective. Minocycline inhibited ischemia-provoked pro-MMP-9 induction in wt mice, but was not protective in MMP-9 ko mice. Pro-MMP-2 was induced by MCAO in wt and MMP-9 ko mice. MCAO-induced pro-MMP-2 was downregulated by minocycline treatment in wt mice but remained in MMP-9 ko mice at the same level as in saline-treated wt mice. Tetracyclines are protective in permanent MCAO when the treatment is started before the insult. Minocycline may provide protection by interfering with MMPs.

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.
