Abstract: In the present study, effect of Na-Bu on the pRb phosphorylation was analysed in the primary cultures of 12 VS tumors. Primary cultures of VS tumors were established from the fresh tumor tissues removed surgically and were treated with Na-Bu. Na-Bu treatment for 48 h led to morphological changes and apoptotic cell death in VS tumor cells. Na-Bu treatment decreased level of total pRb and phosphorylated form of pRb and caused specific dephosphorylation at Ser 249/Thr 252 and Ser 567. In the untreated and Na-Bu treated cells (when present), pRb was localised in the nucleus. Moreover, in Na-Bu treated cells the nucleus appeared highly condensed as compared to untreated cells. Results of the present study indicated that Na-Bu treatment modulated pRb phosphorylation status and caused apoptotic cell death in VS tumors.
