However,the cause of the cognitive dysfunction remains unclear. METHODS Gab1^(loxP/loxP) were bred with ChAT-Cre mice to generate ChAT-Cre; Gab1^(f/f) mice. Excitability of cholinergic neurons wererecorded using whole-cel patch clump. A series of behavioral analyses were used to address the changes of cognitive function in ChAT-Cre; Gab1^(f/f) mice. Neurochemical changes on brain of conditional knockout mice were evaluated by using immunohistochemistry and Western blotting analysis. RESULTS Grb2-associated-binding protein 1(Gab1) is adocking/scaffolding molecule known to play an important role in cell growth and survival. Here,wereport that Gab1 is decreased in cholinergic neurons in a mousemodel of AD. We found that selective downregulation of Gab1 in the septum impaired learning and memory and hippocampal long-term potentiation,whereas overexpression of Gab1 in the same area rescued the cognitive deficitsseen in ChAT-Cre; Gab1^(f/f) and APP^(swe)/PS1 mice.^(18)F-FDGmicroP ET imaging data indicated that Gab1 treatment had no effect on metabolic activity of glucose in APPswe/PS1 mice. Moreover,we identify abnormal function of SKchannelscontributes to increased firing in cholinergic neuronsof ChAT-Cre; Gab1^(f/f) mice. CONCLUSION Gab1 signaling may serve as a potential treatment target for neurological disorders involving dysfunction of central cholinergic neurons.展开更多

Methods One hundred and twelve patients with unresectable HCC were randomly divided into two groups (A and B) to receive superselective TACE. Low-dose anticancer drugs including mitomycin C (MMC) 2 ～ 8 mg,epirubicin (EPI) 5 ～ 10 mg and carboplatin (CBP) 100 mg were used in group A (n = 52),and conventional-dose of anticancer drugs (MMC 10 mg,EPI 40 mg and CBP 300 mg)for patients in group B(n = 60). Lipiodol-anticancer drugs emulsion was injected into the feeding arteries of tumor and then followed by embolization of gelatin sponge (GS) or polyvinyl alcohol (PVA) particles. Laboratory examination of the liver function including Child-Pugh scores,total bilirubin (TBIL),albumin (ALB) and alanine aminotransferase (ALT) were evaluated respectively before TACE and at third day,one week and four weeks after this procedure. Results In both groups,TBIL,ALT,and Child-Pugh scores increased (P < 0.001 or P < 0.05) and ALB decreased (P < 0.001 or P < 0.01) at three days and one week after TACE. Four weeks after-procedure,all the parameters described above showed no significant difference than those before the procedure in group A (P > 0.05). On the contrary in group B,a significant difference (P < 0.05) was found in the comparison of these parameters (except ALT). Conclusion Superselective TACE with low-dose anticancer drugs may induce transient impairment of liver function in the patients with HCC,but those patients used conventional-dose of anticancer drugs frequently cause lasting and more serious worsening of liver function.

Of note, the NAMPT metabolic pathway connects NAD-dependent sirtuin signaling, constituting a strong intrinsic defense system against various stresses. Most recently, we and others have demonstrated several mechanisms by which NAMPT might serve as a therapeutic target against ischemic stroke, including cerebroprotection in the acute phase as well as vascular repair and neurogenesis in the chronic phase. The molecular mechanisms underlying these bene- fits have been explored in vivo and in vitro for neural cells, endothelial progenitor cells, and neural stem cells. Therapeutic interventions using NMN, NAMPT activators and ischemic conditioning are promising for stroke salvage and rehabilitation. Here, we discuss the current NAMPT data in the context of translational efforts for stroke treat- ment.展开更多

Methods The networks between the ingredients/drugs and relevant target proteins for XZD, GXBD, and modern anti-CAD drugs were constructed, respectively. A master network based on the three established networks was further generated. By comparing the similarities and the differences of the targets containing in the master net- work between the individual formula and the modern drugs, the potential anti-CAD targets for XZD and GXBD were i- dentified for further pharmacological investigations. Results Although the herbal formulations and the chemical con- stituents of XZD and GXBD were significant different, both formulas presented the great similarity on target proteins and with the Tanimoto coefficient of 0. 7225. Comparison the formula-specific targets to modem drugs targets, 50 mu- tual targets with higher possibility were modulated. Moreover, a total amount of 114 mutual targets between formulas derived from the master network were identified to be not yet related to those of the approved anti-CAD drugs. Among them, the top 10 targets were identified to be NOS3, PTPN1, GABRA1, PRKACA, CDK2, MAOB, ESR1, ADH1C, ADH1B and AKR1B1. The formula-specific targets of XZD or GXBD which were not yet covered by the current anti- CAD drugs provided the potential opportunities to discovery of the new drug candidates from the two formulas for CAD treatment. Conclusion The established method of network analysis provides a novel approach for screening of the potential therapeutic targets based on the chemical constituents in traditional Chinese medicines or formulas. It is cru- cial for this work to select relatively favorable therapeutic areas of traditional Chinese medicines, syndrome-oriented formulas and syndrome differentiation of same diseases. Meanwhile, this kind of work is helpful for unveiling the mo- lecular mechanism of TCM formulas.展开更多

Numerous somatic genetic markers in eg tyrosine kinase receptors or transcription factors have been identified to be indicative for the treatment with anti-cancer drugs. In contrast, only some recommendations have been developed considering hereditary variants in drug metabolizing enzymes such as TPMT, DYPD or UGT1A1. Although a huge knowledge has been gained on the association of drug transporters variants such as ABCB1 or ABCG2 and clinical outcome, the overall data is inconsistent and the predictability of the related phenotype is low. However, there is increasing evidence that individual phenotypic differences may result not only from genetics, but also from epigenetic alterations such as histone-acetylation or DNA-methylation. Moreover,interactions with non-coding RNAs contribute to protein expression and may modulate drug action. Currently intriguing developments of novel therapeutic approaches through epigenetic drugs are emerging. The overall complexity of epigenetics in drug action is so far only little understood. Of significant importance are the consequences of mi RNA interaction for drug resistance in cancer by regulating target genes and efflux transporters. Further intriguing findings address DNAmethylation as modifier of transporter function and its consequences in cancer development and treatment. The progress of science may lead to the discovery of rare, but functionally relevant SNPs and a better understanding of multiple genomic, epigenomic as well as phenotypic factors, contributing to drug response in malignancies.展开更多

Viral infection and cancer are biologically and medically correlated and in many ways share common cellular pathways that lead to disease development or progression. Better understanding how these signaling events are specifically activated by different pathogenic stimuli and how they activate different downstream transcriptions in response to these stimuli at high specificity and efficiency will provide a new molecular basis for the development of novel disease biomarkers and therapeutic or preventive targets against both classes of diseases. Research in our laboratory has been prompted to investigate the regulation and modes of action of these pathways, with a more intensive focus on the NF-κB signaling, in the settings of severe or oncogenic viral infection as well as cancer development. It is hoped that our research will lead to eventual clinical application of biomarkers derived from these signaling pathways.展开更多
