Oral administration of NPC43 counters hyperglycemia and activates insulin receptor in streptozotocin-induced type 1 diabetic mice.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionAdenosine, 5'-Se-methyl-5'-seleno-,2',3'-diacetate (NPC43) is a recently identified small, non-peptidyl molecule which restores normal insulin signaling in a mouse model of type 2 diabetes (Lan RESEARCH DESIGN AND
methodsIn this study, STZ was intraperitoneally injected into wild-type mice to induce hyperglycemia and hypoinsulinemia, the main features of T1D. These STZ-induced T1D mice were given NPC43 orally or intraperitoneally and blood glucose levels were measured using a glucometer. Protein levels of phosphorylated and total Insrβ, protein kinase B (Akt) and AS160 (critical for glucose uptake) in the skeletal muscle and liver of STZ-induced T1D mice following oral NPC43 treatment were determined by western blot analysis. In addition, hepatic expression of activated Insr in STZ-induced T1D mice after intraperitoneal NPC43 treatment was measured by ELISA. Student's t-test was used for statistical analysis.
resultsOral administration of NPC43 at a dose of 5.4 or 10.8 mg/kg body weight (mpk) effectively lowered blood glucose levels in STZ-induced T1D mice at ≥1 hour post-treatment and the glucose-lowering activity of oral NPC43 persisted for 5 hours. Blood glucose levels were also reduced in STZ-induced T1D mice following intraperitoneal NPC43 (5.4 mpk) treatment. Protein levels of phosphorylated Insrβ, Akt and AS160 were significantly increased in the skeletal muscle and liver of STZ-induced T1D mice after oral NPC43 (5.4 mpk) treatment. In addition, activation of hepatic Insr was observed in STZ-induced T1D mice following intraperitoneal NPC43 (5.4 mpk) treatment.
conclusionsWe conclude that NPC43 is a de facto fast-acting oral and injectable insulin mimetic which activates Insr and mitigates hyperglycemia in a mouse model of T1D.
