  Two key enzymes play important roles in the bioconversion of xylitol from d-arabitol, namely d-arabitol dehydrogenase (ArDH) and NADH-dependent xylitol dehydrogenase (XDH), respectively (Qi et al., 2014). In an earlier study, we developed a high xylitol yield strain by expressing xdh in E. coli BL21

  2020-02-21

  

  Nucleophosmin (NPM1), which also plays a role on the nuclear export of ribosomal proteins and subunits (Maggi et al., 2008), is also a relevant MYC target, presumably through an interaction with CRM1. Conversely, it has been recently reported that specific SINE compounds reduce the levels of MYC in

  2020-02-21

  

  Under conditions of energy scarcity or nutritional restriction, AMPK, a critical energy sensor, is activated in response to the increased ratio of AMP to ATP. Various kinases may phosphorylate AMPK, leading to its activation. For example, AMPK phosphorylation by liver kinase B 1 (LKB1) at Thr172 res

  Introduction Addiction to opioids such as morphine is a chronic disorder that affects the mesocorticolimbic dopaminergic pathway in the brain. Activation of the pathway ultimately leads to dopamine release in the nucleus accumbens (NAc) (Di Chiara et al., 1998) and stimulation of dopamine recepto

  Many studies have found that there is an aberrant DNA methylation in the imprinting control region of development-related genes in the spermatozoa of oligozoospermic men (Kobayashi et al, 2007, Marques et al, 2004, Marques et al, 2008), which most likely results from expressional changes in the DNMT

  (A) An “optimized BEI-SEIscore” based on the trends, emerged from the statistical analysis of several optimization studies in pharmaceutical industry (Abad-Zapatero, 2007, Abad-Zapatero and Blasi, 2011). This type of optimized scores has been used in many previous studies. Ki=1nM at 300° K, compare

  Conventional aromatic radiofluorination via nucleophilic substitution requires electron-withdrawing activating group(s) at the ortho or para position to achieve good radiolabeling yield. In the case of CJ-042794 (), the phenoxy substitution para to the fluoro group is considered an electro-donating

  Of note, BRQ and LFM are two well-known immunosuppressive agents (Batt, 1999). As for LFM, it was reported as immunosuppressive therapy for bone marrow (Avery et al., 2004) and renal (Chon and Josephson, 2011) transplantation. Accumulating evidence indicated that organ transplant patients irrelevant

  Introduction Plasmodium falciparum malaria continues to be a major global cause of mortality and morbidity. Malaria treatment and control has been complicated by the emergence of resistance to widespread antimalarial drug use. The most common method for measuring antimalarial resistance is estima

  DAPK-1 is involved in the p53 dependent apoptotic pathway and it is a mediator of γ-interferon induced apoptosis. DAPK-1 is also involved in other death signaling pathways (tumor necrosis factor-α, CD95 and transforming growth factor-β) and it blocks tumor metastasis in vivo. The loss of DAPK mRNA S

  Some of the psychoactive actions of nicotine are mediated by the nigrostriatal and mesolimbic pathways (Di Chiara, 2000, Di Chiara et al., 2004). The nigrostriatal pathway originates in the dopaminergic neurons located in the substantia nigra and terminates in the putamen and nucleus caudatus which

  In the present study, cells were exposed to a low level of arsenite and a low cytotoxic concentration of BaP. Thus, γ-H2AX loss correlated with repair of DNA damage in cells co-exposed to arsenite and BaP. These results show that arsenite inhibits repair of BaP-induced DNA damage. In a previous stud

  Our published results also show that the Y2 and the Y5, but not the Y1, receptors mediate NPY-induced excitation-secretion coupling in EECs (Abdel-Samad et al., 2012). Thus, it is highly important to consider controlling ET-1 circulating level via blockade of Y2 and/or Y5 receptor activation (Abdel-
