An in vitro lung system to assess the proinflammatory hazard of carbon nanotube aerosols

Barosova, Hana ; Karakocak, Bedia Begum ; Septiadi, Dedy ; Petri-Fink, Alke ; Stone, Vicki ; Rothen-Rutishauser, Barbara

In: International Journal of Molecular Sciences, 2020, vol. 21, no. 15, p. 5335

In vitro three-dimensional (3D) lung cell models have been thoroughly investigated in recent years and provide a reliable tool to assess the hazard associated with nanomaterials (NMs) released into the air. In this study, a 3D lung co-culture model was optimized to assess the hazard potential of multiwalled carbon nanotubes (MWCNTs), which is known to provoke inflammation and fibrosis,...

Different coordination abilities of 1,7- and 4,7-phenanthroline in the reactions with copper(II) salts: Structural characterization and biological evaluation of the reaction products

Stevanović, Nevena Lj. ; Andrejević, Tina P. ; Crochet, Aurélien ; Ilic-Tomic, Tatjana ; Drašković, Nenad S. ; Nikodinovic-Runic, Jasmina ; Fromm, Katharina M. ; Djuran, Miloš I. ; Glišić, Biljana Đ.

The reactions between equimolar amounts of CuX2 (X = NO3− and CF3SO3−) and two aromatic nitrogen-containing heterocycles differing in the position of nitrogen atoms, 1,7- and 4,7-phenanthroline (1,7- and 4,7-phen), were performed in ethanol/methanol at room temperature. When CuX2 salts were mixed with 4,7-phen, two copper(II) complexes, [Cu(NO3)2(4,7-Hphen)2](NO3)2 (1) and...

The Mre11-Nbs1 interface is essential for viability and tumor suppression

Kim, Jun Hyun ; Grosbart, Malgorzata ; Anand, Roopesh ; Wyman, Claire ; Cejka, Petr ; Petrini, John H.J.

In: Cell reports, 2017, vol. 18, no. 2, p. 496-507

The Mre11 complex (Mre11, Rad50, and Nbs1) is integral to both DNA repair and ataxia telangiectasia mutated (ATM)-dependent DNA damage signaling. All three Mre11 complex components are essential for viability at the cellular and organismal levels. To delineate essential and non-essential Mre11 complex functions that are mediated by Nbs1, we used TALEN-based genome editing to derive Nbs1...
