Histone deacetylase (HDAC) inhibitors are promising anticancer drugs but their precise mechanisms of actions are not well understood. Cell-cycle regulation and pro-apoptotic effects of two histone deacetylase inhibitors, suberohydroxamic acid (SAHA) and suberoylanilide hydroxamic acid (SBHA), were analyzed in multiple myeloma cell lines RPMI8226 and U266 with differing TP53 status using gene-expression analysis. Enhanced expression of cyclin-dependent kinase inhibitor 1A (CDKN1A/p21 ) detected in the TP53-deleted U266 cell line after SAHA treatment indicates the P53-independent mode of transcriptional activation of CDKN1A gene. In contrast, CDKN1A gene expression was significantly increased by both SBHA and SAHA treatment of TP53-mutated RPMI8226 cells. SAHA appears to be a potentially effective pro-apoptotic and anticancer drug with universal application in the treatment of heterogeneous populations of multiple myeloma cells.

Traditional Chinese medicine (TCM) Brucea javanica (BJO) has shown anti-proliferation efficacy on human carcinoma cells in vitro. The aim of the present study was to evaluate for the first time the efficacy of BJO combined with the first-line chemotherapeutic drug gemcitabine (GEM) on tumor growth-inhibition and survival in a pancreatic cancer patient-derived orthotopic xenograft (PDOX) mouse model. The pancreatic cancer tumor fragment originated from a patient at the Hefei First People's Hospital (Anhui, PR China). The surgical specimen was transplanted orthotopically in nude mice using surgical orthotopic implantation (SOI). All mice were randomized and assigned to 5 groups G1 saline vehicle (0.1ml per mouse, oral, once
