Alkaline phosphatase as a reporter of sigma(S) levels and rpoS polymorphisms in different E-coli strains
(SPRINGER, 2008)
sigma(S) is responsible for the transcriptional regulation of genes related to protection against stresses and bacterial survival and it accumulates in the cell under conditions of stress, such as nutrient limitation. An ...
La (im)posible articulación entre represión y desmentidaThe (im)possible articulation between repression and disavowal

Increased aerobic metabolism is essential for the beneficial effects of caloric restriction on yeast life span
(SPRINGER/PLENUM PUBLISHERS, 2008)
Calorie restriction is a dietary regimen capable of extending life span in a variety of multicellular organisms. A yeast model of calorie restriction has been developed in which limiting the concentration of glucose in the ...
Repression of Growth Regulating Factors by the MicroRNA396 Inhibits Cell Proliferation by UV-B Radiation in Arabidopsis Leaves
(American Society of Plant Biologist, 2013-09)
Because of their sessile lifestyle, plants are continuously exposed to solar UV-B radiation. Inhibition of leaf growth is one of the most consistent responses of plants upon exposure to UV-B radiation. In this work, we ...

Repression of 5-aminolevulinate synthase gene by the potent tumor promoter, TPA, involves multiple signal transduction pathways
(Elsevier Science Inc, 2005-04)
The potent tumor promoter, 12-O-tetradecanoylphorbol-13-acetate (TPA) induces activator protein-1 (AP-1) transcription factors, early response genes involved in a diverse set of transcriptional regulatory processes, and ...
The Arabidopsis bZIP Gene AtbZIP63 Is a Sensitive Integrator of Transient Abscisic Acid and Glucose Signals
(AMER SOC PLANT BIOLOGISTS, 2011)
Glucose modulates plant metabolism, growth, and development. In Arabidopsis (Arabidopsis thaliana), Hexokinase1 (HXK1) is a glucose sensor that may trigger abscisic acid (ABA) synthesis and sensitivity to mediate glucose-induced ...
