The Eleutherococcus species including 40 species native to Asia are medicinal plants widely used in traditional medicine. Some of these species are cultivated at the botanical gardens in Europe. On the basis on our earlier studies it was concluded that the extracts of analyzed species act as antioxidants, inhibitors of MMPs, and cytotoxic against Jurkat 45 leukemia cell line. In this study, the anti-leukemic potential of roots and leaves from six Eleutherococcus species cultivated in Poland was determined. The in vitro cytotoxic activity towards human promyelotic leukemia cell line HL60 using trypan blue assay was evaluated. The induction of apoptosis in stimulated leukemia cells was determined by AnnexinV method. Morphological changes in treated cells were observed by microscopic investigations. The results showed that ethanolic extracts from the roots and the leaves of E. senticosus, E. setchuensis, E. sessiliflorus, E.gracilistylus, E. henryi and E. divaricatus exhibit cytotoxic effect towards leukemic HL60 cells. The received IC50 values for roots ranged from 49- 208 μg/mL and for the leaves from 116-518 μg/mL. The ethanol extract from the roots of E. divaricatus showed the highest cytotoxic and proapoptotic effect on HL60 human lymphoid leukemia cell line.

The aim of this work was the isolation and identification of phenolic acids from fruit and leaves of Ailanthus glandulosa Desf. The methods used in the isolation and identification of the compounds were: isolation of phenolic acids modified by Ibrahim and Towers, acidic and alkaline hydrolysis by Schmidtlein and Herrmann and identification of phenolic acids in the isolated fraction of two-dimensional thin layer chromatography (TLC) on cellulose plates. In the course of the study, the presence of phenolic acids in leaves and fruit of Ailanthus glandulosa Desf was confirmed. Overall, proportions of 15 phenolic acids were found and identified in the analyzed material. These are: gallic acid, ellagic acid, caffeic acid, gentisic acid, protocatechuic acid, p-hydroxybenzoic acid, m-hydroxybenzoic acid, ferulic acid, p-coumaric acid, syryngic acid, vanillic acid, salicylic acid, 2-hydroxy-4- methoxybenzoic acid, 2,5-dimethoxycinnamic, p-hydroxyphenylacetic acid, and 3 other compounds named A, B, C, whose identification was not possible due to the lack of suitable reference patterns. Studies have shown that leaves and fruit of the plant Ailanthus glandulosa Desf. contain a large number of phenolic acids which possess many important pharmacological activities.

An analysis of the fractions of free acids and phenolic acids liberated by way of hydrolysis in the rhizomes and herbaceous tissues of Sanguisorba officinalis L. was conducted through utilizing the 2D-TLC method. Fifteen phenolic acids were identified. Our work showed that ellagic, protocatechuic, gentisic, p-hydroxybenzoic, syringic, vannilic and ferulic acids were common in all tested fractions, and gallic and protocatechuic acids were dominant in fractions obtained from the rhizomes, while caffeic, p-coumaric, syringic, vannilic and ferulic acids were abundant in the herbaceous tissues. However, α and β - resorcylic acids were detected only in rhizome phenolic acid fractions liberated from their conjunction with sugars and alcohols. Furthermore, chlorogenic acid was present only in a free form in the herbaceous tissues, while p-hydroxyphenylacetic acid was liberated from conjunction from a herbaceous extract.

Introduction. Recent research shows that programmed cell death has great importance in the pathomechanism of atherosclerosis. The BIRC5 and BIRC6 genes belong to Class III IAPs with the anti-apoptotic effect. The proteins display multidirectional action. According to the available literature, in addition to the effect of apoptosis inhibition they also display other properties. It is suggested that they play an important role in the processes of proliferation and cellular differentiation. Aim. The aim of the study was to assess the expression of the BIRC5 and BIRC6 genes in normal peripheral blood lymphocytes and in peripheral blood lymphocytes of patients diagnosed with atherosclerosis. Material and methods. The analysis was carried out on RNA samples obtained from peripheral blood lymphocytes of 21 patients with diagnosed atherosclerosis. The specific fragment of the analysed gene was obtained through amplification with the use of cDNA synthesised in the reaction of reverse transcription. The test of expression was conducted with the use of the Real-Time PCR method. In the studied cases, the level of expression of the analysed gene was compared to the level of expression of the reference gene, B2M. Results. The study showed that mRNA of the BIRC5 and BIRC6 genes is present in the cells of patients with atherosclerosis, as well as in the cells of healthy individuals. The cells taken from the patients with atherosclerosis were mainly characterized by an increased gene expression in comparison to the normal cells. Conclusion. Increased BIRC6 and BIRC5 gene expression in the cells of the patients with atherosclerosis can suggest an increased amount of the inhibitor protein BRUCE and survivin, and also decreased sensitivity of cells to apoptosis. In the case of the patients who had significantly higher expression of the BIRC6 gene in lymphocytes compared to the norm, hypertension and diabetes mellitus were more common

The BIRC6 gene encodes the Bruce (Apollon) protein. This belongs to the III class of Inhibitors of the Apoptosis Protein (IAP) and demonstrates anti-apoptotic activity (binding, inhibiting and degrading the caspases). Moreover, the Bruce protein shows multilevel activities and additional functions. The Bruce protein is involved in the maintenance of cell viability, and it is also suggested that it plays an important role in cell proliferation and diversification. Many researchers have noticed elevated BIRC6 gene expression in cell lines of brain cancer and ovarian carcinoma, leukemia, breast cancer and even in colorectal cancer tissues. Resistance to chemotherapy-inducted apoptosis in cancers characterized by BIRC6 gene over-expression was also reported. The aim of the study was to assess the BIRC6 gene expression in peripheral blood lymphocytes of patients diagnosed with chronic lymphocytic leukemia.
