AB  - The careful monitoring of patients with mild/moderate COVID-19 is of particular importance because of the rapid progression of complications associated with COVID-19. For prognostic reasons and for the economic management of health care resources, additional biomarkers need to be identified, and their monitoring can conceivably be performed in the early stages of the disease. In this retrospective cross-sectional study, we found that serum concentrations of high-mobility group box 1 (HMGB1) and heme oxygenase-1 (HO-1), at the time of hospital admission, could be useful biomarkers for COVID-19 management. The study included 160 randomly selected recovered patients with mild to moderate COVID-19 on admission. Compared with healthy controls, serum HMGB1 and HO-1 levels increased by 487.6 pg/mL versus 43.1 pg/mL and 1497.7 pg/mL versus 756.1 pg/mL, respectively. Serum HO-1 correlated significantly with serum HMGB1, oxidative stress parameters (malondialdehyde (MDA), the phosphatidylcholine/lysophosphatidylcholine ratio (PC/LPC), the ratio of reduced and oxidative glutathione (GSH/GSSG)), and anti-inflammatory acute phase proteins (ferritin, haptoglobin). Increased heme catabolism/hemolysis were not detected. We hypothesize that the increase in HO-1 in the early phase of COVID-19 disease is likely to have a survival benefit by providing protection against oxidative stress and inflammation, whereas the level of HMGB1 increase reflects the activity of the innate immune system and represents levels within which the disease can be kept under control.

AB  - Hypertension and its complications are a leading cause of death in the human
population. Several factors can contribute to development of hypertension, such
as genetic predisposition, high salt intake and environmental stressors, underlying
oxidative stress as one of its key trademarks. We studied the effects of increased salt
intake and chronic stress on blood pressure parameters and the activity and protein
levels of antioxidant enzymes in the heart and aorta of borderline hypertensive rats
(BHRs) with genetic susceptibility to hypertension. All animals were randomized into
four groups: (1) Wistar rats kept in baseline conditions; (2) BHRs kept in baseline
conditions; (3) BHRs drinking 0.9% saline solution; and (4) BHRs drinking 0.9% saline
solution and exposed to repeated heterotypic stress. The BHRs exhibited significantly
higher blood pressure, mitochondrial superoxide dismutase (SOD2) and catalase (CAT)
protein levels and lower glutathione peroxidase (GPx) and glutathione reductase (GR)
activities in the aorta, followed by lower CAT and GPx protein levels and higher CAT
and GR activities in the heart, compared with normotensive Wistar rats. In the BHR
aorta, high salt intake elevated CAT and GPx activities, and when combined with stress
it increased GPx and GR activities. In BHR hearts, high salt intake provoked lower CAT
activity. Adding repeated stress to salt treatment further decreased CAT activity, in
addition to Cu2+–Zn2+ superoxide dismutase (SOD1) and GR activities. The protein
level of CAT was lower, whereas SOD2 and GPx increased. Overall, our results suggest
that BHR hearts are better adapted to oxidative pressure, compared with the aorta,
when exposed to salt and stress.

AB  - Background: Osimertinib belongs to the third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) approved for metastatic EGFR-mutant non-small-cell lung carcinoma (NSCLC) patients. Herein, we studied osimertinib selectivity towards NSCLC cells, its efficacy dependence on the EGFR mutation status, and its ability to evade the classical mechanism of multidrug-resistance (MDR) mirrored in the increased expression of main ATP Binding Cassette (ABC) transporters (ABCB1, ABCC1, and ABCG2).
Methods: Primary patient-derived cultures were established from the NSCLC resections. After short-term culturing (2-3 weeks), a mixed population of cancer and non-cancer cells (around a ratio of 1:1) and two co-cultures of NSCLC cell lines (sensitive NCI-H460 and MDR NCI-H460/R) with lung fibroblasts MRC-5 were treated with 8 chemotherapeutics (cisplatin, carboplatin, paclitaxel, docetaxel, etoposide, vinorelbine, gemcitabine, and pemetrexed) as well as osimertinib. The maximum concentration reached in human plasma to which the patient is exposed during therapy (Cmax) was set as an upper limit and four lower concentrations were also applied during the study. Immunofluorescence assay enabling discrimination of epithelial cancer cells positive to a cocktail of antibodies against cytokeratin 8/18 vs. negative mesenchymal non-cancer cells was conducted using high-content imager ImageXpress Pico (Molecular Devices) with CellReporterXpress 2.9 software. Within the same immunoassay, MDR markers (ABCB1, ABCC1, and ABCG2) were analyzed by corresponding antibodies.
Results: Osimertinib showed selectivity against NSCLC cells, particularly in the patient-derived cell culture without EGFR mutations. Other chemotherapeutics were not selective towards cancer cells, on contrary, they showed higher cytotoxicity in non-cancer cells. Osimertinib did not change the expression of ABCB1 in cancer cells, but it significantly decreased the expression of ABCC1 and ABCG2 transporters in cancer and non-cancer cells.
Conclusions: Osimertinib can be valuable as a selective anticancer drug and an MDR modulator even in NSCLC without EGFR mutations.

AB  - Introduction: Multidrug resistance (MDR) significantly hampers nonsmall cell lung carcinoma (NSCLC) drugs’ efficacy. To evaluate the contribution of MDR markers to anticancer drugs’ sensitivity, we performed pharmacological screening on patient-derived NSCLC cells ex vivo and assessed the expression of MDR markers in cancer and stromal (non-cancer) cells.
Material and Methods: Primary patient-derived cultures were established from the NSCLC resections. After short-term culturing (2-3 weeks), a mixed population of cancer and non-cancer cells were treated with 8 chemotherapeutics (cisplatin, carboplatin, paclitaxel, docetaxel, etoposide, vinorelbine, gemcitabine, and pemetrexed).

Within the same immunoassay, MDR markers (ABCB1, ABCC1, and ABCG2) were analyzed by corresponding antibodies.
Results and Discussions: Among all tested compounds, only gemcitabine increased the number of positive cancer cells to all MDR markers in all investigated primary cell cultures. Pemetrexed did not
change the number of MDR-positive cancer cells. In a patient sample IIIA stage bearing EGFR mutation
(L858R), the number of positive cancer cells to all MDR markers increased upon treatment with cisplatin, carboplatin, paclitaxel, docetaxel, etoposide, vinorelbine, and gemcitabine. Stromal (non-cancer) cells mainly followed the pattern of MDR observed in cancer cells.
Conclusion: Novel functional immunoassay can provide valuable information about the sensitivity of NSCLC to different drugs and possible treatment outcomes based on the
expression of MDR markers.

AB  - Sepsis is a life-threatening condition caused by the dysregulated and overwhelming
response to infection, accompanied by an exaggerated pro-inflammatory state and lipid metabolism
disturbance leading to sequential organ failure. Meldonium is an anti-ischemic and anti-inflammatory
agent which negatively interferes with lipid metabolism by shifting energy production from fatty
acid oxidation to glycolysis, as a less oxygen-demanding pathway. Thus, we investigated the effects
of a four-week meldonium pre-treatment on faecal-induced sepsis in Sprague-Dawley male rats.
Surprisingly, under septic conditions, meldonium increased animal mortality rate compared with
the meldonium non-treated group. However, analysis of the tissue oxidative status did not provide
support for the detrimental effects of meldonium, nor did the analysis of the tissue inflammatory
status showing anti-inflammatory, anti-apoptotic, and anti-necrotic effects of meldonium. After
performing tissue lipidomic analysis, we concluded that the potential cause of the meldonium
harmful effect is to be found in the overall decreased lipid metabolism. The present study underlines
the importance of uninterrupted energy production in sepsis, closely drawing attention to the possible
harmful effects of lipid-mobilization impairment caused by certain therapeutics. This could lead to
the much-needed revision of the existing guidelines in the clinical treatment of sepsis while paving
the way for discovering new therapeutic approaches.

AB  - Background: Sepsis is a life-threatening condition caused by the dysregulated and overwhelming response to infection, accompanied by exaggerated pro-inflammatory state and lipid metabolism disturbance leading to sequential organ failure.1, 2 Meldonium is an anti-ischemic and anti-inflammatory agent, clinically used to treat myocardial ischemia.3 By shifting energy production from fatty acid oxidation to glycolysis, as an oxygen less consuming pathway, meldonium interferes negatively with lipid metabolism. 
Methods: Thus, we investigated the effects of a 4-week meldonium pre-treatment in 300 mg/kg b.m./day dosage on the course of the sepsis induced by a single intraperitoneal injection of faeces (0.5 g faeces/1 mL saline/100 g b.m.)in Sprague-Dawley male rats. The degree of the heart injury was evaluated by measuring tissue pro-apoptotic Bax and anti-apoptotic Bcl-2 ratio, tissue level of the necrotic marker - high mobility group box 1 protein level (HMGB1), together with the heart histology analysis. Sepsis-associated heart inflammation
was assessed by measuring level of an activated form of NF-kB p65 (phospho-NF-κB p65).
Results: In the heart whole homogenates of the septic group of animals (S) HMGB1 level increased 1.7-fold, in comparison to control rats, while meldonium reduced sepsis-induced increase by 18 % (M+S). The underlying mechanism of the proinflammatory action of HMGB1 includes activation of NF-κB signalling
pathways tissue, so the increased HMGB1 level was followed by a 1.4-fold increase of p-NF-κB p65 in the heart of the S group of rats and a 19 % decreased in the heart of M+S group. The apoptotic marker Bax/Bcl-2 ratio changed in the same manner: 1.4-fold increase in the heart of animals from the S group and a 32 % decrease in the heart of the M+S group. On the other hand, heart histology analysis shows that meldonium worsened the heart histological score, causing the severe and diffuse interstitial mononuclear infiltration along with a greater loss of myocytes and myofibrillar contraction band necrosis. The heart lipidomic analysis suggests that meldonium exhibits potentially harmful effects under septic condition due to the lipid-mobilization impairment.
Conclusion: Meldonium exerted anti-inflammatory, anti-apoptotic, and anti- necrotic effects, while it worsened the septic rat heart histology.
