  • Overview and Perspective on RTK Heterointeractions Michael D
    Review Cite This: Chem. Rev. 2019, 119, 5881−5921 pubs.acs.org/CR The RTK Interactome: Overview and Perspective on RTK Heterointeractions Michael D. Paul and Kalina Hristova* Department of Materials Science and Engineering, Institute for NanoBioTechnology, and Program in Molecular Biophysics, Johns Hopkins University, Baltimore, Maryland 21218, United States ABSTRACT: Receptor tyrosine kinases (RTKs) play important roles in cell growth, motility, differentiation, and survival. These single-pass membrane proteins are grouped into subfamilies based on the similarity of their extracellular domains. They are generally thought to be activated by ligand binding, which promotes homodimerization and then autophosphorylation in trans. However, RTK interactions are more complicated, as RTKs can interact in the absence of ligand and heterodimerize within and across subfamilies. 19 Here, we review the known cross-subfamily RTK heterointeractions and their possible biological implications, as well as the methodologies which have been used to study them. Moreover, we demonstrate how thermodynamic models can be used to study RTKs and to explain many of the complicated biological effects which have been described in the literature. Finally, we discuss the concept of the RTK interactome: a putative, extensive network of interactions between the RTKs. This RTK interactome can produce unique signaling outputs; can amplify, inhibit, and modify signaling; and can allow for signaling backups. The existence of the RTK interactome could provide an explanation for the irreproducibility of experimental data from different studies and for the failure of some RTK inhibitors to produce the desired therapeutic effects. We argue that a deeper knowledge of RTK interactome thermodynamics can lead to a better understanding of fundamental RTK signaling processes in health and disease.

  • Distinguishing Pleiotropy from Linked QTL Between Milk Production Traits
    Cai et al. Genet Sel Evol (2020) 52:19 https://doi.org/10.1186/s12711-020-00538-6 Genetics Selection Evolution RESEARCH ARTICLE Open Access Distinguishing pleiotropy from linked QTL between milk production traits and mastitis resistance in Nordic Holstein cattle Zexi Cai1*†, Magdalena Dusza2†, Bernt Guldbrandtsen1, Mogens Sandø Lund1 and Goutam Sahana1 Abstract Background: Production and health traits are central in cattle breeding. Advances in next-generation sequencing technologies and genotype imputation have increased the resolution of gene mapping based on genome-wide association studies (GWAS). Thus, numerous candidate genes that afect milk yield, milk composition, and mastitis resistance in dairy cattle are reported in the literature. Efect-bearing variants often afect multiple traits. Because the detection of overlapping quantitative trait loci (QTL) regions from single-trait GWAS is too inaccurate and subjective, multi-trait analysis is a better approach to detect pleiotropic efects of variants in candidate genes. However, large sample sizes are required to achieve sufcient power. Multi-trait meta-analysis is one approach to deal with this prob- lem. Thus, we performed two multi-trait meta-analyses, one for three milk production traits (milk yield, protein yield and fat yield), and one for milk yield and mastitis resistance. Results: For highly correlated traits, the power to detect pleiotropy was increased by multi-trait meta-analysis com- pared with the subjective assessment of overlapping of single-trait QTL confdence intervals. Pleiotropic efects of lead single nucleotide polymorphisms (SNPs) that were detected from the multi-trait meta-analysis were confrmed by bivariate association analysis. The previously reported pleiotropic efects of variants within the DGAT1 and MGST1 genes on three milk production traits, and pleiotropic efects of variants in GHR on milk yield and fat yield were con- frmed.

  • A Molecular Dynamics Simulation Study for Variant Drug Responses Due to FMS-Like Tyrosine Kinase 3 Cite This: RSC Adv.,2017,7, 29871 G697R Mutation†

Recent studies have suggested that the application of small-molecule kinase inhibitors is a promising treatment strategy for patients with primary activating mutations of FLT3; however, the development of secondary mutations, including those of A627T, N676D, F691I, and G697R, that confer acquired resistance to kinase inhibitors has become a severe problem. In this study, we conducted a series of molecular dynamics simulations on PKC412- and sorafenib-bound FLT3 kinases and different apo forms of the FLT3 kinase to explain the minor and severe G697R mutation-induced resistance to sorafenib and PKC412, respectively. Structural analysis on our simulation results revealed that the type II kinase inhibitor sorafenib (IC50 ¼ 9 nM) Creative Commons Attribution 3.0 Unported Licence. assesses its binding site through either the adenine pocket entrance or the back pocket entrance, whereas the type I kinase inhibitor PKC412 (IC50 ¼ 35 nM) intercalates to its binding site from the front pocket entrance. The G697 residue is located at the end of the FLT3 kinase hinge segment and is close to the front and adenine pockets. In G697R mutation where the substituted R697 residue affects both the front and adenine pocket entrances in different manners, sorafenib may approach its binding site Received 11th April 2017 through the back pocket entrance, whereas PKC412 is blocked by the FLT3 kinase.

EAEP improved cell viability as well as attenuated the formation of intracellular reactive oxygen species (ROS) and apoptotic bodies in glutamate-treated hippocampal neuronal cells (HT-22). Furthermore, EAEP improved the expression of brain-derived neurotrophic factor (BDNF) and antioxidant enzymes such as heme oxygenase-1 (HO-1), NAD(P)H quinine oxidoreductase-1 (NQO-1), and glutamate–cysteine ligase catalytic subunit (GCLC) via the tropomyosin-related kinase receptor B/ protein kinase B (TrkB/Akt) signaling pathway. In contrast, the pre-incubation of K252a, a TrkB inhibitor, or MK-2206, an Akt-selective inhibitor, ameliorated the neuroprotective effects of EAEP in oxidative stress-induced neuronal cells. These results suggest that EAEP protects neuronal cells against oxidative stress-induced apoptosis by upregulating the expression of BDNF and antioxidant enzymes via the activation of the TrkB/Akt pathway. In conclusion, such an effect of EAEP, which is rich in carotenoid-derived compounds, may justify its application as a food supplement in the prevention and treatment of neurodegenerative disorders. Keywords: Enteromorpha prolifera; oxidative stress; apoptosis; BDNF; TrkB/Akt pathway 1.

  • Short-Term Rapamycin Persistently Improves Cardiac Function After Cessation of Treatment in Aged Male and Female Mice
    Short-term rapamycin persistently improves cardiac function after cessation of treatment in aged male and female mice. Ellen Quarles A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2017 Reading Committee: Peter Rabinovitch, Chair Michael MacCoss David Marcinek Program Authorized to Offer Degree: Pathology © Copyright 2017 Ellen Quarles University of Washington Abstract Short-term rapamycin persistently improves cardiac function after cessation of treatment in aged male and female mice. Ellen Quarles Chair of the Supervisory Committee: Peter Rabinovitch, Professor and Vice Chair of Research Department of Pathology Cardiac aging is an intrinsic process that results in impaired cardiac function and dysregulation of cellular and molecular quality control mechanisms. These effects are evident in the decline of diastolic function, increase in left ventricular hypertrophy, metabolic substrate shifts, and alterations to the cardiac proteome. This thesis covers the quality control mechanisms that are associated with cardiac aging, results from an anti-aging intervention in aged mice, and a review of mitochondrial dysfunction in the heart. Chapter one is a review of the quality control mechanisms in aging myocardium. Chapter two consists of the results of several mouse experiments that compare the cardiac function, proteomes, and metabolomes of aged and young controls, along with rapamycin treated aged mice. The novelty of this study comes from the inclusion of a group of animals treated only transiently with the drug, then followed for eight weeks post-drug-removal. This persistence cohort may hold clues to deriving long-lasting benefits of rapamycin with only transient treatment.

  • Chemical Biology of Natural Indolocarbazole Products: 30 Years Since the Discovery of Staurosporine
    The Journal of Antibiotics (2009) 62, 17–26 & 2009 Japan Antibiotics Research Association All rights reserved 0021-8820/09 $32.00 www.nature.com/ja REVIEW ARTICLE Chemical biology of natural indolocarbazole products: 30 years since the discovery of staurosporine Hirofumi Nakano and Satoshi O¯ mura Staurosporine was discovered at the Kitasato Institute in 1977 while screening for microbial alkaloids using chemical detection methods. It was during the same era that protein kinase C was discovered and oncogene v-src was shown to have protein kinase activity. Staurosporine was first isolated from a culture of Actinomyces that originated in a soil sample collected in Mizusawa City, Japan. Thereafter, indolocarbazole compounds have been isolated from a variety of organisms. The biosynthesis of staurosporine and related indolocarbazoles was finally elucidated during the past decade through genetic and biochemical studies. Subsequently, several novel indolocarbazoles have been produced using combinatorial biosynthesis. In 1986, 9 years since its discovery, staurosporine and related indolocarbazoles were shown to be nanomolar inhibitors of protein kinases. They can thus be viewed as forerunners of today’s crop of novel anticancer drugs. The finding led many pharmaceutical companies to search for selective protein kinase inhibitors by screening natural products and through chemical synthesis. In the 1990s, imatinib, a Bcr-Abl tyrosine kinase inhibitor, was synthesized and, following human clinical trials for chronic myelogenous leukemia, it was approved for use in the USA in 2001. In 1992, mammalian topoisomerases were shown to be targets for indolocarbazoles. This opened up new possibilities in that indolocarbazole compounds could selectively interact with ATP- binding sites of not only protein kinases but also other proteins that had slight differences in ATP-binding sites.

Received: 9 July 2012; in revised form: 23 August 2012 / Accepted: 4 September 2012 / Published: 14 September 2012 Abstract: The aim of this work was to compare protective and anti-apoptotic effects of α-tocopherol at nanomolar and micromolar concentrations against 0.2 mM H2O2-induced toxicity in the PC12 neuronal cell line and to reveal protein kinases that contribute to α-tocopherol protective action. The protection by 100 nM α-tocopherol against H2O2-induced PC12 cell death was pronounced if the time of pre-incubation with α-tocopherol was 3–18 h. For the first time, the protective effect of α-tocopherol was shown to depend on its concentration in the nanomolar range (1 nM < 10 nM < 100 nM), if the pre-incubation time was 18 h.
