Thymosin β4 cytoplasmic/nuclear translocation as a new marker of cellular stress. A Caco2 case study.

Biomarkers of cell stress are important for proper diagnosis, and in studies of how cells respond to drug treatment. Biomarkers that respond early to pharmacological treatment could improve therapy by tailoring the treatment to the needs of the patient. Thymosin beta-4 (Tβ) plays a significant role in many aspects of cellular metabolism because of its actin-sequestering properties.
