Abstract

BACKGROUND

Estrogen Receptor α (ERα), a member of the nuclear receptor superfamily of transcription factors, plays a central role in breast cancer development. More than two-thirds of patients with breast cancer are ERα-positive; however, a proportion becomes resistant. Phosphorylation of ERα is one of the mechanisms associated with resistance to endocrine therapy. In a kinome screen, we have identified the large tumor suppressor homolog-2 (LATS2) as a potential kinase, acting on ERα.

MATERIALS AND METHODS

The role of LATS2 on activation of ERα transcription and its functional consequences was examined by various molecular and cellular biology techniques.

RESULTS

LATS2 co-localises with ERα in the nucleus. LATS2-silencing increases expression of ERα-regulated genes and inhibits proliferation. At the protein level, inhibition of LATS2 reduces the expression of cyclin-D1 and Nuclear Receptor Co-Repressor (NCoR) while increasing the expression of p27.

CONCLUSION

Identifying novel kinases which modulate ERα activity is relevant to therapeutics. LATS2 modulates ERα-regulated gene transcription, through direct and/or indirect interactions with ERα.
