Hairy root culture plays an important role in investigation of alkaloid production in culture in vitro. The complexity of scientific work and the production capacity limitations associated with whole plant systems and unorganized cells can be overcome using culture of hairy roots. This paper presents an example of a strategy to produce secondary metabolites from plants, in which we investigated...

Lymphomatoid papulosis is a rare skin disease. The incidence averages 1.5 cases per 1 million population. It the most common in adults around age of 40. was previously considered as paraneoplastic dermatosis, but recent studies have confirmed that lymphomatoid primary CD30 + T-lymphoma skin. Despite aggressive morphological features, it benign. disease characterized by tendency to spontaneous r...

Hairy polyp is a rare, benign tumor that comprises ectodermal and mesodermal germ layers. The embryogenesis of hairy polyp is precisely unknown, and concurrently, it has a female predominance. Although hairy polyp is observed in every part of the body; it is frequently located in the nasopharynx and oropharynx. Respiratory distress and feeding difficulties are the most related symptoms. Differe...

Analysis of genes preferentially expressed in hairy roots caused by infection with Agrobacterium rhizogenes has provided insights into the regulation of lateral root formation. A hairy root preferential cDNA, HR7, has been cloned from hairy roots of Hyoscyamus niger. HR7 encodes a novel protein partially homologous to a metallocarboxypeptidase inhibitor and is expressed exclusively in the primo...

Linum spp. (Linaceae) has been shown to accumulate cytotoxic lignans such as podophyllotoxin and 6-methoxypodopyllotoxin. Therefore, plant cell and tissue cultures of Linum spp. may be possible alternative sources for the lignan production. In this study, we focused on the production of lignans by root cultures of Linum spp. Hairy root cultures of L. nodiflorum, L.album and L. austriacum and ro...

Background & Aim:A new sustainable tissue-based system is presented by plant hairy roots, preserving all of the several specialized types of cell with critical roles in allowing bioactive secondary molecules to be synthesized more consistently as usual. The system is also essential for studying the production of alkaloid in culture. Experimental: The ...

hairy root systems are formed by transforming plant tissues with the “natural genetic engineer” agrobacterium rhizogenes. in most plants such as cichorium intybus l., hairy root cultures have proven to be an efficient system for secondary metabolites production. the effect of zinc (znso4), a heavy metal, was investigated at different concentrations (0, 1, 5 and 10 mm) on some secondary metaboli...

Protein Phosphatase 6 down-regulation in keratinocytes is a pivotal event that amplifies the inflammatory circuits psoriasis, indicating restoration of protein phosphatase can be rational strategy for psoriasis treatment. Through phenotypic screen, we here identify L-menthol ameliorates psoriasis-like skin inflammation by increasing keratinocytes. Target identification approaches reveal an indi...
