  Our data also showed that D2 dopamine receptor was down-regulated in the hippocampus, NAc and striatum of F1-MEP animals, which was only significant in the hippocampus. Both agonists and antagonists of D2 dopamine receptor are able to decrease heroin self-administration (Hemby et al., 1996; Rowlett

  In this report, we present spectroscopic evidence on the effect of different solvents having proton acceptor and proton donor ability and pH of the medium on the abstraction of amino proton of PI (Scheme 1) for controlling the nonradiative rates. Despite the general utility of PI as a DNA intercalat

  For reductive amination by L-AmDH, the term related to the enzyme-ammonia complex is excluded rather than the enzyme-pentanone term (Table 1). If this were an ordered mechanism, this would imply ammonia binds second, after NADH and before 2-pentanone. However, a large KM,NH4 value renders ammonia bi

  In cancer, interactions between the transformed cancer PFI-2 and other cell types recruited to the tumor are important. Tumor associated macrophages provide cancer cells with a suitable low-grade inflammatory milieu including growth promoting factors. Our results suggest a novel pro-tumorigenic mech

  2019-11-01

  

  The Liver X Receptor-α and -β (LXRs, NR1H3 and NR1H2, respectively) are members of the nuclear receptor superfamily that play a central role in controlling cholesterol homeostasis [9], [10]. In macrophages, LXRs can decrease the cellular sterol burden by inducing expression of the cholesterol efflux

  From these and other studies, it is clear that acriflavine is an interesting imidazoline with pleiotropic anticancer effects [21], [22], [43]. Its past systemic use in the clinical setting as an antibiotic without any major toxicity reported encourages further development of the drug for cancer tre

  Besides EGFR, other tyrosine kinase receptors are currently gaining attention as potential therapeutic targets. Included among these is the fibroblast growth factor receptor (FGFR) family, which is involved in the progression of a variety of cancers.7, 8, 9, 10, 11 In lung cancer, fibroblast growth

  Discussion The regulation of intracellular cholesterol levels is a biological process of vital importance for cellular function and integrity, and involves robust transcriptional and post-transcriptional mechanisms that are sensitive to metabolic feedback control. Amongst post-transcriptional mec

  A second advance came with the discovery that conformationally-flexible benzamide analogs having an N-phenylpiperazine moiety possessed good affinity and modest selectivity for D3 versus D2 receptors [3,[14], [15], [16]]. This observation spawned a significant effort by medicinal chemists to develop

  Transcription can also be impaired by lesions in the template DNA strand, which may lead to stalling of RNA polymerase (RNAP) or to transcriptional mutagenesis, thus producing mutant RNAs and proteins [[3], [4], [5], [6], [7]]. At the same time, RNAP can act as a sensor for DNA lesions, by attractin

• ATP dependent DNA ligases in vertebrates

  2019-10-31

  

  ATP-dependent DNA ligases in vertebrates are divided in three families [7]. Family I DNA ligases are responsible for sealing the nicks during DNA replication and in long-patch base excision repair (BER). Family III DNA ligases are involved in short-patch BER. Lastly, family IV DNA ligases are involv

  Results Discussion Repair by NHEJ implicitly requires the pairing together of broken chromosome ends. A complex of Ku, XRCC4, DNA ligase IV, and XLF (PEC) is necessary and sufficient for this purpose (Reid et al., 2015). Here, we describe dynamic changes in this complex that are triggered by d

  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
