Histone deacetylases (HDACs) inhibition causes hyperacetylation of histones leading to growth arrest, differentiation and apoptosis of tumor cells, representing a new strategy in cancer therapy. Many of previously reported HDACs inhibitors are hydroxamic acid derivatives, which could chelate the zinc ion in the active site in a bidentate fashion. However, hydroxamic acids occasionally have produced problems such as poor pharmacokinetics, severe toxicity and low selectivity. Herein we describe the identification of a new series of non-hydroxamate HDACs inhibitors bearing diketo ester moieties as zinc binding group. HDACs inhibition assay and antiproliferation assays in vitro against multiple cancer cell lines were used for evaluation. These compounds displayed low antiproliferative activity against solid tumor cells, while good antiproliferative activity against human leukemic monocyte lymphoma cell line U937. Compound CPUYS707 is the best with GI50 value of 0.31 micromol x L(-1) against U937 cells, which is more potent than SAHA and MS-275. HDACs inhibition activity of these compounds is lower than that expected, further evaluation is needed.

Aim To investigate the effects of Aplysin on the inhibition of gastric cancer cell in vitro .Methods MTT assay was used to examine the inhibition of gastric cancer cell 1ine SGC-7901 by Aplysin in different concentrations and at different times.The morphologic changes and the apoptosis of SGC-7901 was observed by inverted microscope and Hematoxylin-Eosin(HE)staining.Reverse transcriptase polymerase chain reaction(RT-PCR)assay was used to detect the changes of COX-2 mRNA expressions.Results Aplysin could decrease the proliferation significantly in a dose-dependent manner in SGC-7901 cells.When treating SGC-7901 with Aplysin in concentration of 120, 240 mg·L~(-1) for 24 h, the growth of the cell was obviously inhibited observing by inverted microscope.Aiso, when treating with the same concentration for 18 h, its chromatin became crimpled and breakdown, as well as cell shrinkage and apoptotic bodies formation when using HE staining.The apoptotic rates(%)of SGC-7901 was(15.0±2.12)%, (18.4±2.3)%, respectively, which was significantly higher than(1.4±0.55)% that in control group(P <0.01).60、120、240 mg·L~(-1) Aplysin could not effectively inhibited the mRNA expressions of COX-2(P ＞0.05).Conclusions Aplysin can inhibit the proliferation and induces apoptosis of SGC-7901 cells.

Aim To investigate the effects of diallyl di-sulfide( DADS) on G2/M arrest in Chk1/MGC803 and Chk2/MGC803 cells so as to establish stable human gastric cancer MGC803 cells with overexpression of Chk1/2 gene. Methods The colony formation, flow cytometry, RT-PCR and Western blot were used to de-tect the proliferation, cell cycle, and expression of Chk1/2 mRNA and protein, p-Chk1/2, CDC25C and cyclinB1, respectively. Results The colony formation showed that the colony forming efficiency in Chk1/MGC803 and Chk2/MGC803 cells treated by 30 mg· L-1 DADS was lower than in control group and vector group ( P <0. 05 ) . Flow cytometry demonstrated that 41. 3%, 57. 4%, 68. 9% and 42. 9% of G2/M cells in Chk1/MGC803 were increased than in MGC803 and Chk2/MGC803 , respectively after treated by DADS in 12,24, 36 and 48 h(P <0. 05). At the same time, RT-PCR disclosed that expression of Chk1 and Chk2 mRNA had no marked change. Western blot showed that total proteins of Chk1 and Chk2 and p-Chk2 had invisible change, but expression of p-Chk1 was up-reg-ulated, and CDC25C and cyclinB1 were down-regula-ted time-dependently in Chk1/MGC803 cells ( P <0. 05 ) . Conclusion DADS arrests MGC803 cells at G2/M by increasing p-Chk1 expression to cause down-regulation of CDC25C and cyclinB1 simultaneously.

To establish single- and double-transfected transgenic cells stably expressing hMATE1, hMATE1 cDNA was cloned by RT-PCR from human cryopreserved kidney tissue, and subcloned into pcDNA3.1(+) plasmid by virtue of both HindIII and Kpn I restriction enzyme sites. Subsequently, the recombined pcDNA3.1(+)- hMATE1 plasmid was transfected into MDCK, MDCK-hOCT1 or MDCK-hOCT2 cells using Lipofectamine 2000 Reagent. After a 14-day-cultivation with hygromycin B at the concentration of 400 µg · mL(-1), all clones were screened with DAPI and MPP+ as substrates to identify the best candidate. The mRNA content of hMATE1, the cellular accumulation of metformin with or without cimetidine as inhibitor, or transportation of cimetidine was further valuated. The results showed that all of the three cell models over expressed hMATE1 mRNA. The cellular accumulation of metformin in MDCK-hMATE1 was 17.6 folds of the control cell, which was significantly inhibited by 100 µmol · L(-1) cimetidine. The transcellular transport parameter net efflux ratios of cimetidine across MDCK-hOCT1/hMATE1 and MDCK-hOCT2/hMATE1 monolayer were 17.5 and 3.65, respectively. In conclusion, cell models with good hMATE1 function have been established successfully, which can be applied to study the drug transport or drug-drug interaction involving hMATE1 alone or together with hOCT1/2 in vitro.

OBJECTIVETo explore the mechanisms of acupuncture treatment promoting the motor function recovery of neonate rats with cerebral palsy.

METHODSThe improved hypoxic-ischemic encephalopathy (HIE) means was performed to establish the model of neonate rats with cerebral palsy. All neonate rats were randomly divided into 3 groups: sham group, model group and acupuncture group (n = 20). We observed and scored motor function of rats, measured the levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in serum, and also measured the expression of synaptophysin (SYP) and growth associated protein-43 (GAP-43) in the diseased region of cerebral tissue.

RESULTSThe motor function scores (11.3 +/- 0.29) and the serum level of SOD (147.1 +/- 12.7) U/ml in acupuncture treatment group were higher than those of model group ( P < 0.05). The serum level of MDA was lower in acupuncture treatment group than that of model group (P < 0.05). The expression of SYP and GAP-43 in the diseased region of cerebral tissue of acupuncture treatment group were higher than those of model group ( P < 0.05) .

CONCLUSIONAcupuncture-therapy could improve the motor function of neonate rats with cerebral palsy by decreasing the content of MDA in serum, increasing the contents of SOD in serum, and prolonging the upregulation of SYP and GAP-43 expressions in hmin tissue.

Objective To investigate the clinical value of low-dose decitabine (DAC) in elderly patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) patients with intermediate-or high-risk. Methods Low-dose DAC (10 mg/d, 7 days) combined with CAG regimen were given to 19 elderly patients with AML and intermediate- or high-risk MDS patients. The efficacy and adverse reactions were evaluated after a course of treatment, and the patients were followed up for survival. Results After a course of treatment, 8 patients achieved complete remission (CR), 7 patients achieved partial remission (PR). After 4 courses of treatment, 68.4 % (13/19) of patients achieved CR, the overall response rate reached 78.9% (15/19). Fewer side effects were seen associated with chemotherapy. After 42 months of follow-up, there were 12 survival cases, the median survival time was 13.5 months (3-42 months). Conclusion Low-dose DAC combined with CAG regimen have a better efficacy, higher safety, and lower economic burden for elderly AML patients and intermediate- or high-risk MDS patients, which is beneficial to greatly improve patients' compliance.

Objective To investigate the clinical characteristics and methods of diagnosis and treatment of granular lymphocytic leukemia (LGLL).Methods Clinical data of 3 patients with LGLL were retrospectively analyzed and relevant literature was reviewed.Results 3 patients were all onset with lymphocytosis,whose conditions progressed slowly.The diagnosis of 2 patients was T-LGLL with immunological characteristics of CD3+ CD4 CD8+ CD56-CD57+.The other patient' s diagnosis was NK-LGLL,whose immunological characteristic was CD3-CD4-CD8-CD56+ CD57-.Two of them didn' t need any treatment.One of them was treated with cyclosporine because of agranulocytosis and recurrent infection.Conclusions LGLL is a group of heterogeneous diseases,which clinical characteristic and prognosis are different.Flow cytometric immunopheotype,TCR Vβ analysis and TCR gene rearrangement are helpful to diagnosis.
