We examined the effect of resveratrol (RVT) and its two derivatives (3,3′,4,4′-tetrahydroxy-trans-stilbene and 3,3′,4,4′,5,5′-hexahydroxy-trans-stilbene) on human peritoneal mesothelial cell (HPMC)-dependent angiogenesis in vitro. To this end, angiogenic activity of endothelial cells (HUVEC, HMVEC, and HMEC-1) was monitored upon their exposure to(More)
The role of mesothelial cells in the intraperitoneal spread of ovarian cancer is still elusive. In particular, it is unclear whether these cells constitute a passive barrier preventing cancer cell progression or perhaps act as an active promoter of this process. In this report we show that omental human peritoneal mesothelial cells (HPMCs) stimulate(More)
Gastrointestinal cancers metastasize into the peritoneal cavity in a process controlled by peritoneal mesothelial cells (HPMCs). In this paper we examined if senescent HPMCs can intensify the progression of colorectal (SW480) and pancreatic (PSN-1) cancers in vitro and in vivo. Experiments showed that senescent HPMCs stimulate proliferation, migration and(More)
The aim of our study was to examine the irritation potential of new eye drops containing 2% choline salicylate (CS) as an active pharmaceutical ingredient (API) and various polymers increasing eye drop viscosity (hydroxyethylcellulose, hydroxypropyl methylcellulose, methylcellulose, polyvinyl alcohol, polyvinylpyrrolidone). The standard method for assessing(More)
In this project we examined how the presence of human peritoneal mesothelial cells (HPMCs) modifies (supports or inhibits) colorectal and pancreatic cancer cell progression in mice peritoneal cavity. Experiments were performed using primary, omentum-derived HPMCs, commercially available colorectal (SW-480) and pancreatic (PSN-1) cancer cells, and(More)
Sirtuins are a NAD(+)-dependent deacetylases involved in several cellular processes like e.g. transcriptional silencing, regulation of apoptosis, fat homeostasis and aging. Mammalian sirtuins are located in cytoplasm, nucleus as well as mitochondria. The sirtuins exhibit a number of intriguing biological properties and increase of their activity was(More)
Sir2 proteins known as sirtuins belong to the family of NAD(+)-dependent deacetylases. Seven mammalian homologues belonging to the family of Sir2 proteins (SIRT2 1-7) were identified. Due to catalytic activity involving multiple substrates, sirtuins play an important role in regulating processes prerequisite to proper functioning of the body. They exhibit(More)
About 30-60% of patients with schizophrenia show resistance to neuroleptic treatment. In about 5-20% of them the resistance to antipsychotic treatment appears during the first therapy (primary resistance), however in the rest of patients, treatment resistance develops during 5 to 10 years of the illness (secondary resistance). In addition, another group of(More)
Natural product derived from plants and animals were used in folk medicine for centuries. The venoms produced by animals for hunting of self-defence are rich in bioactive compounds with broad spectrum of biological activity. The papers presents the most promising compounds isolated from venoms of snakes, scorpions and toads. For these compounds both:(More)
The role of CYP1A1 and CYP1B1 enzymes in the biotransformation and biological activity of the methylated resveratrol analogue, 3,4,5,4'-tetramethoxystilbene (DMU-212) is still elusive. Our recently published data have shown that one of the metabolites of DMU-212, 3'-hydroxy-3,4,5,4'-tetramethoxystilbene (DMU-214) exerts more potent cytotoxic effects in(More)
