CLN7 neuronal ceroid lipofuscinosis is an inherited lysosomal storage neurodegenerative disease highly prevalent in children. CLN7/MFSD8 gene encodes a lysosomal membrane glycoprotein, but the biochemical processes affected by CLN7-loss of function are unexplored thus preventing development of potential treatments. Here, we found, in the Cln7 ∆ex2...

The neuronal ceroid lipofuscinoses (NCLs) are a family of monogenic life-limiting pediatric neurodegenerative disorders collectively known as Batten disease ¹ . Although genetically heterogeneous ² , NCLs share several clinical symptoms and pathological hallmarks such as lysosomal accumulation of lipofuscin and astrogliosis 2,3 . CLN7 disease belon...

We utilized a deep neural network to search for host-target acting antivirals among experimental and approved drugs with potential activity against coronavirus-born diseases. To achieve the goal we searched for gene expression signatures of molecular perturbations most closely resembling the effects of the COPB2 gene knockout since COPB2 is require...

The glycolytic rate in neurons is low in order to allow glucose to be metabolized through the pentose-phosphate pathway (PPP), which regenerates NADPH to preserve the glutathione redox status and survival. This is controlled by 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase-3 (PFKFB3), the pro-glycolytic enzyme that forms fructose-2,6-bisphos...

During metastatic growth, cells of solid tumors undergo phenotypical changes related to epithelial-mesenchymal transition. Epithelial-mesenchymal transition is regarded as a potential target for prospective antitumor drugs. Fluorescent reporter systems for evaluation of the expression of markers of epithelial and mesenchymal status (E- and N-cadher...
Article
The possibility of interactions between warfarin and dasatinib and their interactions with other drugs metabolized by cytochrome P450 isoform CYP3A4 was demonstrated using a previously created cytochrome P450 substrate—inhibitor panel for preclinical in vitro studies of drug biotransformation on a 3D histotypical microfluidic cell model of human li...
Article
We developed a cytochrome P450 substrate-inhibitor panel for preclinical in vitro evaluation of drugs in a 3D histotypical microfluidic cell model of human liver (liver-on-a-chip technology). The concentrations of substrates and inhibitors were optimized to ensure reliable detection of the principal metabolites by HPLC-mass-spectroscopy. The select...
Article
We studied the relationship between microcirculation parameters and functional status of HepaRG cells in spheroids and chose an optimal regimen within the physiologically permissible limits of mechanical impact for the cells that maintains the expression of functional genes of the liver.
Article
We studied the effects of DMSO and fibroblasts during HepaRG cell spheroid formation and conditions of their subsequent culturing on the levels of mRNA of the major cytochromes P450. A protocol of spheroid formation from differentiated HepaRG cells and their culturing in serum- and DMSO-free medium is developed.

Abietane diterpenes have attracted much attention because they display a wide range of biological activities, including antitumor activities. These compounds are the most diverse of the diterpenoids isolated from species of Plectranthus. Naturally occurring diterpene parvifloron D is the main phytochemical constituent of Plectranthus ecklonii. To e...
Article
In the present study, the cytotoxicity of 30 diterpenoids with an abietane or a halimane skeleton was determined against five human tumor cell lines (HL-60, U937, Molt-3, SK-MEL-1, and MCF-7). Diterpenoids containing an abietane skeleton including taxodone (1) and taxodione (2), as well as the semisynthetic derivatives 12, 14, 15, 17, and 22, were...

Flavonoids are naturally occurring polyphenolic compounds which display a vast array of biological activities. In this study, we investigated the effects of tamarixetin on viability of human tumor cell lines and found that it was cytotoxic against leukemia cells and in particular P-glycoprotein-overexpressing K562/ADR cells. This compound inhibited...

A new cysteine protease (SpCP) with a molecular mass of about 50 kDa and optimal functioning at pH 8.0 was isolated from the culture medium of a Serratia proteamaculans 94 psychrotolerant strain using affinity and gel permeation chromatography. The enzyme N terminal amino acid sequence (SPVEEAEGDGIVLDV-) exhibits a reliable similarity to N terminal...

MicroRNAs (miRNAs) are a class of small regulatory RNAs that control a level of expression of protein encoding genes. Their role in brain pathologies is unknown. We made a first attempt to carry out a genetic study coupled with gene expression analysis of microRNA in human neuropsychiatric pathology. Presumably, at least one third of known miRNA ge...
