Identified RNA molecules that regulate action of male hormone in prostate cancer

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

A study detected in tumoral tissue hundreds of RNAs that do not encode proteins but appear to regulate effects of androgens and androgen receptors on gene expression in tumors. By investigating the connection between the presençe of these molecules and tumor aggressiveness, the research paves the way for new scientific approaches focusing on the transcription process of noncoding RNA.

Study describes enzyme's key role in immune response to Chagas disease parasite

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

A study shows that the expression of PI3Kγ protein increases during infection by T. cruzi, an essential response in avoiding excessive inflammation and controlling parasitemia. Heart tissue analyses involving human patients who developed cardiopathy in the disease's chronic stage also provided results. The next challenge is to devise treatment for Chagas using molecules capable of modulating the cellular signaling pathway mediated by PI3Kγ.
