Exogenous LEA proteins expression enhances cold tolerance in mammalian cells by reducing oxidative stress.

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
Understanding the molecular mechanisms that confer cold resistance in mammalian cells might be relevant for advancing medical applications. This study aimed to exploit the protective function of Late Embryogenesis Abundant (LEA) proteins, known to provide resistance to low temperatures in extremophiles and plants, by their exogenous expression in mammalian cells, and compare their effects with the well characterized antioxidant, vitamin E.Remarkably, the expression of LEA proteins in mammalian cells exerted cold-protective effect similar to Vitamin E. LEA proteins preserved cell viability during cold stress and ensured a normal metabolic activity after warming. Their protective action was due to the mitigation of cold-induced mitochondrial stress and the overproduction of reactive oxygen species (ROS), leading in turn to enhanced cytoskeleton stability and decreased DNA damage. Our studies showed that plant-derived LEA proteins exhibit remarkable cold protection effects in mammalian cells through their potent antioxidant properties, which was found comparable to Vitamin E.
