Alternaria Alternata Toxins Synergistically Activate the Aryl Hydrocarbon Receptor Pathway in Vitro
biomolecules Article Alternaria alternata Toxins Synergistically Activate the Aryl Hydrocarbon Receptor Pathway In Vitro Julia Hohenbichler 1 , Georg Aichinger 1 , Michael Rychlik 2 , Giorgia Del Favero 1 and Doris Marko 1,* 1 Department of Food Chemistry and Toxicology, University of Vienna, 1090 Vienna, Italy; [email protected] (J.H.); [email protected] (G.A.); [email protected] (G.D.F.) 2 Chair of Analytical Chemistry, Technical University of Munich, 80333 Munich, Germany; [email protected] * Correspondence: [email protected] Received: 18 June 2020; Accepted: 30 June 2020; Published: 9 July 2020 Abstract: Alternaria molds simultaneously produce a large variety of mycotoxins, of which several were previously reported to induce enzymes of phase I metabolism through aryl hydrocarbon receptor activation. Thus, we investigated the potential of naturally occurring Alternaria toxin mixtures to induce Cytochrome P450 (CYP) 1A1/1A2/1B1 activity. Two variants of an extract from cultured Alternaria alternata, as well as the toxins alternariol (AOH), alternariol monomethyl ether (AME), altertoxin I (ATX-I), and altertoxin II (ATX-II), were tested singularly and in binary mixtures applying the 7-ethoxy-resorufin-O-deethylase (EROD) assay in MCF-7 breast cancer cells. Sub-cytotoxic concentrations of the two toxin mixtures, as well as ATX-I, ATX-II and AOH, exhibited dose-dependent enhancements of CYP 1 activity. ATX-I and ATX-II interacted synergistically in this respect, demonstrating the two perylene quinones as major contributors to the extract’s potential. Binary mixtures between AOH and the two altertoxins respectively exhibited concentration-dependent antagonistic as well as synergistic combinatory effects. -

A Day in the Life of the Vice-Chancellor
A Day in the Life of the Vice-Chancellor rofessor Joseph J.Y. Sung has been Vice-Chancellor of CUHK for several months, and so far, a hectic schedule is the norm rather Pthan the exception. One day in November 2010, he treated patients, taught students, gave lectures, received University guests, officiated at a ceremony, and attended a student gathering. From dawn to dusk, he shifted between his many roles, but always with zeal and composure. 8:15 am. The Vice-Chancellor cast a towering shadow at the entrance to the CUHK-PWH Medical Centre in the morning light, his doctor’s coat a reminder of the role by which Hong Kong first knew him. He had not just arrived. He had been at the Prince of Wales Hospital since 7:30 am for a meeting. He was scheduled to see patients at the medical centre, something he said he would continue to do before taking up the vice-chancellorship. ‘Good morning, Vice-Chancellor. How are you? You seem so much busier than when you were a professor. Thanks for making time to see me.’—A typical greeting as such is a valid proof of patients’ awareness of the many hats the doctor is wearing. Two Year 5 medical students joined Sung at the clinic. He spoke to the patient in Cantonese and explained the condition to the students in English. At one point, he spent eight minutes explaining the pros and cons of two drugs, as well as the correct dosage and the criteria for choosing one over the other. -
Academic Freedom in Hong Kong Since 2015: Between Two Systems
Academic Freedom in Hong Kong since 2015: Between Two Systems Kevin Carrico January 2018 Hong Kong Watch Academic Freedom in Hong Kong 1 EXECUTIVE SUMMARY The state of academic freedom in Hong Kong is a microcosm of the state of “one country, two systems” as a whole. It is alive, and generally well, but only due to constant public vigilance against growing threats. Hong Kong’s students and scholars played a central role in the 2014 Occupy protests for political reform. As a result, since early 2015, a growing top-down backlash has attempted to limit academic freedom and bring academia under the authorities’ control. This post-Occupy retribution is manifested in the following trends: • Controversial academic figures have been removed from their posts, seen promotions blocked, or faced extra-legal campaigns to pressure their removal. These were all driven by political motivations. • State-appointed and politically connected figures have governed universities in a manner divorced from the will of students and faculty. • There is a growing push to place limits on freedom of speech, without any legal basis. Although academic work in Hong Kong remains considerably freer than in the rest of the People’s Republic of China, these trends suggest that elements of academic control in place elsewhere in China are gradually being incorporated into the Hong Kong system, threatening the city’s academic freedom and thus its universities’ reputations. POLICY RECOMMENDATIONS • Educators must directly and openly confront “taboo” topics in Hong Kong, or run the risk of enabling a censorship regime that will continually expand, swallowing up new topics as forbidden. -

Digestive Diseases 063 LI KA SHING INSTITUTE of HEALTH SCIENCES PROGRESS REPORT 2016
Appendix: Digestive Diseases 063 LI KA SHING INSTITUTE OF HEALTH SCIENCES PROGRESS REPORT 2016 01 Research Progress Summary DIGESTIVE DISEASES A. Molecular pathogenesis 1. Using a genome-wide shRNA screen in colorectal cancer (CRC) cells with mutations in APC and KRAS, the team identified a novel oncogenic candidate SLC25A22. SLC25A22 plays an important role in tumour metabolism in KRAS-mutant CRC by promoting biosynthesis of the nonessential amino acid aspartate. SLC25A22 protein and mRNA levels were independent prognostic markers associated with poor survival in KRAS-mutant CRC patients. 2. Whole genome sequencing has identified solute carrier family 12 member 5 (SLC12A5) as a novel amplification gene in colorectal cancer. SLC12A5 possessed oncogenic properties by promoting tumour proliferation and metastasis, and inhibiting cell apoptosis. SLC12A5 protein overexpression was found to be an independent prognostic factor associated with shortened survival in colorectal cancer patients. 3. Using methylated DNA immunoprecipitation array, the team identified Carbonic Anhydrase 4 (CA4) as a novel tumour suppressor gene silenced in colorectal cancer through promoter methylation. CA4 inhibited Wnt signalling pathway via WTAP–WT1–TBL1 axis, thereby suppressing colorectal cancer development. The team also found that methylation status of CA4 may serve as an independent biomarker for the recurrence of CRC. 4. Sequencing of fimH gene of Escherichia coli (E. coli) leads to the identification of α-hemolysin-positive (hly+) type 1 E.coli that contributes to adenomagenesis and CRC in human females. Hly+ type 1-E. coli were more prevalent in stools from females with adenoma and CRC and their abundance was correlated with poor survival. Feeding hly+ type 1-E. -
Application of Various Molecular Modelling Methods in the Study of Estrogens and Xenoestrogens
International Journal of Molecular Sciences Review Application of Various Molecular Modelling Methods in the Study of Estrogens and Xenoestrogens Anna Helena Mazurek 1 , Łukasz Szeleszczuk 1,* , Thomas Simonson 2 and Dariusz Maciej Pisklak 1 1 Chair and Department of Physical Pharmacy and Bioanalysis, Department of Physical Chemistry, Medical Faculty of Pharmacy, University of Warsaw, Banacha 1 str., 02-093 Warsaw Poland; [email protected] (A.H.M.); [email protected] (D.M.P.) 2 Laboratoire de Biochimie (CNRS UMR7654), Ecole Polytechnique, 91-120 Palaiseau, France; [email protected] * Correspondence: [email protected]; Tel.: +48-501-255-121 Received: 21 July 2020; Accepted: 1 September 2020; Published: 3 September 2020 Abstract: In this review, applications of various molecular modelling methods in the study of estrogens and xenoestrogens are summarized. Selected biomolecules that are the most commonly chosen as molecular modelling objects in this field are presented. In most of the reviewed works, ligand docking using solely force field methods was performed, employing various molecular targets involved in metabolism and action of estrogens. Other molecular modelling methods such as molecular dynamics and combined quantum mechanics with molecular mechanics have also been successfully used to predict the properties of estrogens and xenoestrogens. Among published works, a great number also focused on the application of different types of quantitative structure–activity relationship (QSAR) analyses to examine estrogen’s structures and activities. Although the interactions between estrogens and xenoestrogens with various proteins are the most commonly studied, other aspects such as penetration of estrogens through lipid bilayers or their ability to adsorb on different materials are also explored using theoretical calculations.
