Role of thymosin beta 4 in hair growth.

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
Although thymosin beta 4 (Tβ4) is known to play a role in hair growth, its mechanism of action is unclear. We examined the levels of key genes in a Tβ4 epidermal-specific over-expressing mouse model and Tβ4 global knockout mouse model to explore how Tβ4 affects hair growth. By depilation and histological examination of the skin, we confirmed the effect of Tβ4 on hair growth, the number of hair shafts and hair follicle (HF) structure. The mRNA and protein expression of several genes involved in hair growth were detected by real-time PCR and western blotting, respectively. Changes in the expression of β-catenin and Lef-1, the two key molecules in the Wnt signaling pathway, were similar to the changes observed in Tβ4 expression. We also found that compared to the control mice, the mRNA and protein expression of MMP-2 and VEGF were increased in the Tβ4 over-expressing mice, while the level of E-cadherin (E-cad) remained the same. Further, in the Tβ4 global knockout mice, the mRNA and protein levels of MMP-2 and VEGF decreased dramatically and the level of E-cad was stable. Based on the above results, we believe that Tβ4 may regulate the levels of VEGF and MMP-2 via the Wnt/β-catenin/Lef-1 signaling pathway to influence the growth of blood vessels around HFs and to activate cell migration. Tβ4 may have potential for the treatment of hair growth problems in adults, and its effects should be further confirmed in future studies.
