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

When faced with nutrient deprivation, Saccharomyces cerevisiae cells enter into a nondividing resting state, known as stationary phase. The Ras/PKA (cAMP-dependent protein kinase) signaling pathway plays an important role in regulating the entry into this resting state and the subsequent survival of stationary phase cells. The survival of these resting cells is also dependent upon autophagy, a membrane trafficking pathway that is induced upon nutrient deprivation. Autophagy is responsible for targeting bulk protein and other cytoplasmic constituents to the vacuolar compartment for their ultimate degradation. The data presented here demonstrate that the Ras/PKA signaling pathway inhibits an early step in autophagy because mutants with elevated levels of Ras/PKA activity fail to accumulate transport intermediates normally associated with this process. Quantitative assays indicate that these increased levels of Ras/PKA signaling activity result in an essentially complete block to autophagy. Interestingly, Ras/PKA activity also inhibited a related process, the cytoplasm to vacuole targeting (Cvt) pathway that is responsible for the delivery of a subset of vacuolar proteins in growing cells. These data therefore indicate that the Ras/PKA signaling pathway is not regulating a switch between the autophagy and Cvt modes of transport. Instead, it is more likely that this signaling pathway is controlling an activity that is required during the early stages of both of these membrane trafficking pathways. Finally, the data suggest that at least a portion of the Ras/PKA effects on stationary phase survival are the result of the regulation of autophagy activity by this signaling pathway.
