Role of the androgen receptor in melanoma aggressiveness.

Malignant melanoma represents the fifth most common cancer in the world and its incidence is rising. Novel therapies targeting receptor tyrosine kinases, kinases and immune checkpoints have been employed with a significant improvement of the overall survival and long-term disease containment. Nevertheless, the disease often progresses and becomes resistant to the therapies.

Chromatin looping links gene expression to the assembly of transcription factories (Review).

Genes are not randomly dispersed within the nuclear space, instead they occupy precise sites either with respect to the nuclear lamina as well as to each other. This observation stands at the basis of the today well accepted concept of nuclear territories where any chromosome shows reproducible spatial connections with a selection of others in a general picture that meets a functional criterion where genes that answer the same stimuli are grouped in the same sites. In fact, transcription is not visible widely dispersed throughout the nucleus but is gathered in several 'granules', called transcription factories that accommodates ~10 genes concurrently transcribed.

Filamin A in triple negative breast cancer.

Triple-negative breast cancer is a rare but highly heterogeneous breast cancer subtype with a limited choice of specific treatments. Chemotherapy remains the only efficient treatment, but its side effects and the development of resistance consolidate the urgent need to discover new targets. In TNBC, filamin A expression correlates to grade and TNM stage.

Filamin A cooperates with the androgen receptor in preventing skeletal muscle senescence.

Aging induces a slow and progressive decrease in muscle mass and function, causing sarcopenia. Androgens control muscle trophism and exert important anabolic functions through the binding to the androgen receptor. Therefore, analysis of the androgen receptor-mediated actions in skeletal muscle might provide new hints for a better understanding of sarcopenia pathogenesis.
