I was going to answer that there are none when I stumbled on a report about 3 PC cell lines from Brazil which were described in 2010 and which I had not yet entered in the Cellosaurus. You will find here the two relevant papers:
Piantino C.B., Salvadori F.A., Ayres P.P., Kato R.B., Srougi V., Leite K.R., Srougi M.; An evaluation of the anti-neoplastic activity of curcumin in prostate cancer cell lines; Int. Braz. J. Urol. 35:354-360(2009).
PubMed=19997870; DOI=10.1007/s11626-009-9249-7;
Piantino C.B., Sousa-Canavez J.M., Bellodi-Privato M., Srougi M., Camara-Lopes L.H., Gattas G.J.F., Goncalves F.T., Fridman C., Leite K.R.M.; Establishment and characterization of androgen-independent human prostate cancer cell lines, PcBra1, PcBra2, and PcBra3; In Vitro Cell. Dev. Biol. Anim. 46:123-130(2010).
And the 3 preliiminary entries for the Cellosaurus:

As these cell lines are not distrbuted by any cell line collections, you will need to contact the laboratory in Brazil directly. Also note that there has not been any publication since the original ones in 2009-2010, so its not certain that these cell lines are still available. Anyway you should try and let me know in this thread if you did get access to them.
