Abstract
Placenta is a highly specialized organ that is necessary for successful gestation. Several models of the placental barrier are used to study how it functions, including the transplacental transport of xenobiotics. One of these models, human choriocarcinoma cell line BeWo is widely used in vitro. Notably, cancerous BeWo cells form multilayer structures that normally are not found in the human placenta. Here, we aim to develop techniques suitable for monitoring BeWo b30 cells in culture. To assess the state of BeWo b30 cells growing on a membrane, we use impedance spectroscopy, which allows us to estimate the number of cell layers by the change in the electrical parameters of the biological system. In mature BeWo b30 cell cultures, we also note a significant increase in the expression of genes encoding metallothioneins (particularly, MT1B, MT1F, and MT2A) and syncytins (ERVW-1 and ERVFRD-1), which can be used as biomarkers reflecting the development of mature phenotypic characteristics, namely, trophoblastic invasion and formation of the syncytium.

Abstract
Drug bioavailability studies commonly employ in vitro barrier tissue models consisting of epithelial and endothelial cells. These experiments require that the cell barrier quality be assessed regularly, which is usually performed using various labeled substrates and/or evaluation of transepithelial (transendothelial) electrical resistance (TEER). This technique provides information on the integrity of the monolayer, but not on differentiation-induced changes in the cell morphology. The present work shows that impedance spectroscopy can be applied to monitor both the integrity of the monolayer and the morphological changes of Caco-2 cells. The growth kinetics of the apical membrane was determined by calculating the electrical capacitance of the cell monolayer. In the course of differentiation, the most pronounced changes in the expression levels were observed for the mRNAs that encode SLC30A10 and SLC23A3 transporters. Their increase correlated with an increase in the apical membrane area, indicating that SLC30A10 and SLC23A3 mRNA levels assessed by qRT-PCR may be employed as cell differentiation biomarkers in Caco-2 models.

Abstract
Extracellular microRNA are one of the indicators of the functional state of cells. Culturing of Caco-2 cells under the conditions of microcirculation in a Homunculus microfluidic device allows better simulating natural environment of the body in comparison with static culturing. Impedance spectroscopy (BioClinicum Research Center) was used for non-invasive estimation of the monolayer quality and changes in the cell apical membrane due to the formation of microvilli. Under static conditions, Caco-2 cells release more microRNA from the apical membrane than under microcirculation conditions, while secretion of miR-320a, miR-24-3p, and miR-221-3p microRNA under static conditions can indicate stress of the cells and activation of inflammatory response. Under microcirculation conditions, the expression of laminin-α1 (LAMA1) was lower than under static conditions, which indicates deeper differentiation of cells.

Abstract
We compared available methods for monitoring the integrity of in vitro models of barrier tissues and studied the possibility of using impedance spectroscopy to solve this problem. It was demonstrated (theoretically and experimentally) that TEER measurements are not sufficiently sensitive to detect small defects in the cell barrier that significantly affect its permeability. For obtaining reliable results, it is necessary to set a sufficiently high threshold TEER, which leads to the loss of many intact samples. At the same time, impedance spectroscopy has all advantages of the classical method of measuring TEER (it is rapid and non-invasive method), while its application in combination with the methods of machine learning allows reliable detection of defects in the cell barrier.

Abstract
BACKGROUND "Branched tail" oxyquinolines, and adaptaquin in particular, are potent HIF prolyl hydroxylase inhibitors showing promising results in in vivo hemorrhagic stroke models. The further improvement of the potency resulted in identification of a number of adaptaquin analogs. Early evaluation of toxicity and metabolism is desired right at the step of lead selection. OBJECTIVE The aim of the study is to characterize the toxicity and metabolism of adaptaquin and its new improved analogs. METHOD Liver-on-a-chip technology with differentiated HepaRG cells followed by LC-MS detection of the studied compounds and metabolites of the P450 substrate-inhibitor panel for CYP2B6, CYP2C9, CYP2C19, and CYP3A4. RESULTS The optimized adaptaquin analogs show no toxicity up to a 100-fold increased range over EC50. The drugs are metabolized by CYP3A4 and CYP2B6 as shown with the use of the cytochrome P450 substrate-inhibitor panel designed and optimized for preclinical evaluation of drugs' in vitro biotransformation on a 3D human histotypical cell model using "liver-on-a-chip" technology. Activation of CYP2B6 with the drugs tested has been observed. A scheme for adaptaquin oxidative conversion is proposed. CONCLUSION The optimized adaptaquin analogs are suitable for further preclinical trials. Activation of CYP2B6 with adaptaquin and its variants points to a potential increase in Tylenol toxicity if administered together.

Abstract
The mistletoe lectin viscumin (MLI) is a ribosome-inactivating protein from Viscum album widely used in cancer therapy. Its antitumor properties are due to its immunomodulating action, previously demonstrated in experiments involving intravenous, subcutaneous, and oral administration of viscumin. To investigate whether viscumin has a cytotoxic effect on the intestinal epithelium, its safety was assessed using (i) impedance spectroscopy to measure the integrity of the colorectal adenocarcinoma Caco-2 cell monolayer after exposure to viscumin and (ii) a novel technique of determining the portion of viscumin-inactivated ribosomes. It was shown that inactivation of at least 20% of the ribosomes within 6 h did not lead to disruption of the Caco-2 cell monolayer or alter the physicochemical parameters of enterocyte membranes.
