Prognostic significance of cytoplasmic SOX9 in invasive ductal carcinoma and metastatic breast cancer.

SOX9, a high mobility group (HMG) box transcription factor, is required for development, differentiation and lineage commitment. It is known to exert its effects through nuclear translocation, such as cell cycle changes in response to retinoic acid treatment in breast cancer cells. However, it is not known whether SOX9 has prognostic significance in human breast cancer.

Understanding behavioral and physiological phenotypes of stress and anxiety in zebrafish.

The zebrafish (Danio rerio) is emerging as a promising model organism for experimental studies of stress and anxiety. Here we further validate zebrafish models of stress by analyzing how environmental and pharmacological manipulations affect their behavioral and physiological phenotypes. Experimental manipulations included exposure to alarm pheromone, chronic exposure to fluoxetine, acute exposure to caffeine, as well as acute and chronic exposure to ethanol.

Qui non proficit, deficit: experimental models for 'integrative' research of affective disorders.

Experimental models are an important tool for the study of biological mechanisms of psychiatric disorders. Although encouraging progress has been made in biological psychiatry of affective disorders, there remain numerous methodological, conceptual, and translational challenges in this field. Mounting clinical data support the view that psychiatric disorders as spectra, rather than as discrete or isolated illnesses.
