In earlier experiments on snails, a behavioral model was employed of certain food rejection to study the mechanisms of the reconsolidation of long-term associative memory. It was found that conditioned food stimuli (reminder) presentation, combined with injections of NMDA glutamate receptor antagoni

Nowadays, more than 500 kinases have been identified of human genome [2]. Imatinib (Gleevec) was the first tyrosine kinase inhibitor approved by the US Food and Drug Administration (FDA) for the treatment of chronic myeloid leukemia [3], and kinases have become an attractive target for the developme

Mechanisms of homeostasis At face value, homeostatic mechanisms may seem like nothing more than a simple balance between opposing forces; however, the ability of Mec1/Tel1 to each orchestrate both negative and positive regulation greatly complicates the system under consideration and argues again

2023-02-08
Somatostatin analogs also bind to somatostatin receptors. It has been reported that octreotide has a high affinity for hSSTR2, moderate affinity for hSSTR3 and hSSTR5, and does not bind to hSSTR1 or hSSTR4 (Ben-Shlomo and Melmed 2008). Compared to octreotide, pasireotide displays 40-, 30-, and 5-fol

In this study, we showed that TRIM48 promotes ASK1 activation through ubiquitination-dependent degradation of a negative regulator of ASK1 activation, protein arginine methyltransferase 1 (PRMT1). Knocking down TRIM48 suppressed oxidative-stress-induced cell death mediated by ASK1, and the additiona

AP-1 activity is increased by MAP kinase stimulation in different cell types (Whitmarsh and Davis, 1996), while MKP-1, the enzyme that catalyzes the dephosphorylation and inactivation of MAP kinases in the nucleus, inhibits AP-1 (Rössler et al., 2008, Rössler and Thiel, 2009, Mayer et al., 2011, Thi

Materials and methods Results Discussion Endophilin A1 is a membrane-binding protein that is mainly distributed in the central nervous system (Giachino et al., 1997), localizes in the dendritic shafts and spines of mature neurons (Yang et al., 2015), and relates to the function and morpholo

Moreover, mice exposed to high-cholesterol diet have mildly activated astrocytes, increased expression of ApoE and aquaporin-4 in the hippocampus, and altered levels of proteins associated with Aβ metabolism (Chen et al., 2016), which is related to a higher demand for cholesterol transport and the n

Synthesis of the pterin-7-carboxamides was achieved, as shown in , based on a previously reported method that utilizes DBU as a key additive to dissolve pterin in organic solvents and accelerate the reaction., With this method, the pterin-amino daunorubicin conjugates (–) were readily obtained by

Pregnane X receptor (PXR) is a nuclear receptor that plays an important role in regulation of metabolism and disposition of structurally diverse xenobiotics as well as endogenous steroids and bile acids (Bertilsson et al., 1998, Kliewer et al., 1998, Lehmann et al., 1998). PXR regulates the metaboli

A clear link between α2-ADR stimulation and decreased respiration in β-cells is established and consistent with proteomics data. Current discoveries in islets have identified physical interactions between ADR-coupled G proteins and cellular components such as insulin vesicles and ion channels (Zhao

The biological characteristics of cancer invasion and metastasis are mainly attributed to the poor prognosis in cancer. It has been reported that overexpression of Ack1 promoted the migratory and invasive properties of breast cancer TPMPA by sustaining expression of epidermal growth factor. In cont

Using constant potential amperometry and electrochemical enzyme-based biosensors selective for choline—and, therefore, an accurate readout of 5-EdU release (Baker et al., 2015; Bruno et al., 2006a; Parikh et al., 2004, 2007)—tonic and phasic release of acetylcholine were measured simultaneously in t
