1 · What the graph read from it

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.

2 · The registry

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

The metal-dependent histone deacetylases (HDACs) adopt an alpha/beta protein fold first identified in rat liver arginase. Despite insignificant overall amino acid sequence identity, these enzymes share a strictly conserved metal binding site with divergent metal specificity and stoichiometry. HDAC8, originally thought to be a Zn(2+)-metallohydrolase, exhibits increased activity with Co(2+) and Fe(2+) cofactors based on k(cat)/K(M) (Gantt, S. L., Gattis, S. G., and Fierke, C. A. (2006) Biochemistry 45, 6170-6178). Here, we report the first X-ray crystal structures of metallo-substituted HDAC8, Co(2+)-HDAC8, D101L Co(2+)-HDAC8, D101L Mn(2+)-HDAC8, and D101L Fe(2+)-HDAC8, each complexed with the inhibitor M344. Metal content of protein samples in solution is confirmed by inductively coupled plasma mass spectrometry. For the crystalline enzymes, peaks in Bijvoet difference Fourier maps calculated from X-ray diffraction data collected near the respective elemental absorption edges confirm metal substitution. Additional solution studies confirm incorporation of Cu(2+); Fe(3+) and Ni(2+) do not bind under conditions tested. The metal dependence of the substrate K(M) values and the K(i) values of hydroxamate inhibitors that chelate the active site metal are consistent with substrate-metal coordination in the precatalytic Michaelis complex that enhances catalysis. Additionally, although HDAC8 binds Zn(2+) nearly 10(6)-fold more tightly than Fe(2+), the affinities for both metal ions are comparable to the readily exchangeable metal concentrations estimated in living cells, suggesting that HDAC8 could bind either or both Fe(2+) or Zn(2+) in vivo.
