HNRNPK and posterior cortical atrophy: In human and murine PCa cells, hnRNP K and AR colocalize in the nucleoplasm in a complex that is highly proximal to DNA, and treatment with bicalutamide (BIC) and/or 4-hydroxy-tamoxifen results in anomalous hnRNP K phosphorylation and in a consequent modulation of the complex [6].
