At present, more than 50 000 plant species are used in phytotherapy and medicine. About 2/3 of them are harvested from nature leading to local extinction of many species or degradation of their habitats. Biotechnological methods offer possibilities not only for faster cloning and conservation of the genotype of the plants but for modification of their gene information, regulation, and expression for production of valuable substances in higher amounts or with better properties.Rhodiola roseais an endangered medicinal species with limited distribution. It has outstanding importance for pharmaceutical industry for prevention and cure of cancer, heart and nervous system diseases, and so forth. Despite the great interest in golden root and the wide investigations in the area of phytochemistry, plant biotechnology remained less endeavoured and exploited. The paper presents research on initiation ofin vitrocultures inRhodiola roseaand some otherRhodiola species. Achievements in induction of organogenic and callus cultures, regeneration, and micropropagation varied but were a good basis for alternativein vitrosynthesis of the desired metabolites and for the development of efficient systems for micropropagation for conservation of the species.

The use of infusions and extracts from domestic plant materials is a promising direction in the development of functional beverages since they contain a wide range of substances of various pharmacological properties. Drinks fortified with physiologically active natural components maintain a certain level of this content in human body. They can have a healing or prophylactic effect. However, there is a lack of technologies for the effective production of biologically active substances from plant materials. Moreover, the development of cultivated botanical medicinal plant species remains quite poor. The present study features the qualitative and quantitative composition of biologically active substances of medicinal plants that are endemics of Siberia. They are Rhodiola rosea (Rhodiola rosea L.) and maral root (Rhaponticum carthamoides). The paper introduces a method for increasing their biosynthetic activity. An experiment helped to select a composition of the nutrient medium for the cultivation of callus cultures of Rhodiola rosea (Rhodiola rosea L.) and maral root (Rhaponticum carthamoides) in vitro, which contributed to an increase in the biosynthesis of biologically active substances. For callus cultures of Rhodiola Rosea (line R.r-1k) the following composition was used: mineral base – MS; sucrose – 30 g; inositol – 100 mg; thiamine – 1.0 mg; pyridoxine – 1.0 mg; Ca-panthetonate – 10 mg; kinetin – 0.05 g; naphthyl acetic acid – 0.1 g; 2.4-D – 0.5. For callus cultures of maral root (line R.c -2k): mineral base – SH; sucrose – 30 g; inositol – 100 mg; thiamine – 5.0 mg; pyridoxine – 0.5 mg; nicotinic acid – 5.0 mg; kinetin – 0.1 g; indoleacetic acid – 1.0 g. The authors developed a technology for the production of functional whey-based tonic drink fortified with extract of carotenoids isolated from the fruits of mountain ash and the extract of biologically active substances Rhodiola rosea and maral root. The presence of biologically active substances in the plant and medicinal raw materials gives the drink antioxidant and bactericidal properties, as well as helps to raise the overall state of the organizm and strengthen the immune system.

Introduction. Geroprotectors are biologically active substances that inhibit the aging process. Many plant species are natural geroprotectors. For instance, Thymus vulgaris and Trifolium pratense are callus cultures with strong geroprotective properties. Study objects and methods. The present research featured T. vulgaris and T. pratense grown in vitro on various nutrient media. Their extracts were obtained by aqueous-alcoholic extraction using the following parameters: water-ethanol solvent Se = 30, 50, and 70 %; temperature Te = 30, 50, and 70°C; time τe = 2, 4, and 6 h. The quantitative and qualitative analysis was based on high-performance liquid mass spectrometry, gas mass spectrometry, and thin-layer chromatography. Results and discussion. The optimal extraction parameters for T. vulgaris were τe = 4 h, Te = 50°C, Se = 70 %, for T. pratense – τe = 6 h, Te = 70°C, Se = 70 %. The chromatography detected flavonoids, phenylpropanoids, simple phenols, higher fatty acids, mono- and sesquiterpenes, and aliphatic hydrocarbons. T. vulgaris appeared to have the highest content of thymol (23.580 ± 1.170 mg/mL); its thymol, apigenin, gallic, chlorogenic, and caffeic components demonstrated geroprotective properties. The extract of T. pratense possessed the highest rutin content (10.05 ± 0.35 mg/mL), and it owed its geroprotective characteristics to rutin, chlorogenic and p-coumaric acids. Conclusion. The callus cultures of T. vulgaris and T. pratense proved to be promising sources of geroprotective biologically active substances.

PURPOSE AND DESIGN: The purpose of this review is to provide an overview of the literature linking Ras signaling pathways and leukemia and to discuss the biologic and potential therapeutic implications of these observations. A search of MEDLINE from 1966 to October 1998 was performed. RESULTS: A wealth of data has been published on the role of Ras pathways in cancer. To be biologically active, Ras must move from the cytoplasm to the plasma membrane. Importantly, a posttranslational modification—addition of a farnesyl group to the Ras C-terminal cysteine—is a requisite for membrane localization of Ras. Farnesylation of Ras is catalyzed by an enzyme that is designated farnesyltranferase. Recently, several compounds have been developed that can inhibit farnesylation. Preclinical studies indicate that these molecules can suppress transformation and tumor growth in vitro and in animal models, with little toxicity to normal cells. CONCLUSION: An increasing body of data suggests that disruption of Ras signaling pathways, either directly through mutations or indirectly through other genetic aberrations, is important in the pathogenesis of a wide variety of cancers. Molecules such as farnesyl transferase inhibitors that interfere with the function of Ras may be exploitable in leukemia (as well as in solid tumors) as novel antitumor agents.

Cystic fibrosis (CF) is an inherited disease associated with chronic severe lung inflammation, leading to premature death. To develop innovative anti-inflammatory treatments, we need to characterize new cellular and molecular components contributing to the mechanisms of lung inflammation. Here, we focused on the potential role of “transient receptor potential vanilloid-4” (TRPV4), a nonselective calcium channel. We used both in vitro and in vivo approaches to demonstrate that TRPV4 expressed in airway epithelial cells triggers the secretion of major proinflammatory mediators such as chemokines and biologically active lipids, as well as a neutrophil recruitment in lung tissues. We characterized the contribution of cytosolic phospholipase A2, MAPKs, and NF-κB in TRPV4-dependent signaling. We also showed that 5,6-, 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acids, i.e., four natural lipid-based TRPV4 agonists, are present in expectorations of CF patients. Also, TRPV4-induced calcium mobilization and inflammatory responses were enhanced in cystic fibrosis transmembrane conductance regulator-deficient cellular and animal models, suggesting that TRPV4 is a promising target for the development of new anti-inflammatory treatments for diseases such as CF.
