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

We investigated whether nuclear factor kappa B (NF-kappaB), which exhibits a regulated pattern of activity during murine mammary gland development, plays an important role during lactation and involution, when milk production ceases and the gland undergoes apoptosis and re-modeling. We generated a doxycycline inducible transgenic mouse model to activate NF-kappaB specifically in the mammary epithelium through expression of a constitutively active form of IKK2, the upstream kinase in the classical NF-kappaB signaling cascade. We found that activation of NF-kappaB during involution resulted in a more rapid reduction in milk levels and increased cleavage of caspase-3, an indicator of apoptosis. We also found that activation of NF-kappaB during lactation with no additional involution signals had a similar effect. The observation that NF-kappaB is a key regulator of milk production led us to investigate the role of NF-kappaB during mastitis, an infection of the mammary gland in which milk loss is observed. Mammary gland injection of E. coli LPS resulted in activation of NF-kappaB and milk loss during lactation. This milk loss was decreased by selective inhibition of NF-kappaB in mammary epithelium. Together, our data reveal that activation of NF-kappaB leads to milk clearance in the lactating mammary gland. Therefore, targeting of NF-kappaB signaling may prove therapeutic during mastitis in humans and could be beneficial for the dairy industry, where such infections have a major economic impact.
