β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations
Advanced Biology, Volume 9, Issue 3, March 2025.Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Activación del crecimiento de Plantulas de sietecueros (Tibouchin lepidota) por Fitohormonas
Acta Biológica Colombiana, 1996 Many tropical tree species when seedling have a slow growing period that seems to be controlled by a physiological mechanism of hormonal regulation. In "sietecueros" (Tibouchina lepidota (Bnpl.) Baill), different plant hormones like polyamines, auxines ...

The Biophysical Limitations in Physiological Transport and Exchange in Plants Grown in Microgravity
, 2002 This paper describes how changes in the physical behavior of fluids and gases in microgravity can limit the physiological transport and exchange in higher plants. These types of effects are termed indirect effects of microgravity because they are not due
