Background: Papaver bracteatum Lindl. Commonly known as Iranian poppy is an important medicinal plant due to the presence of benzylisoquinoline alkaloids. Objective: To evaluate the hairy root culture as a novel method for thebaine production. Methods: To optimize the hairy root culture of P. bracteatum, five strains of Agrobacterium rhizogenes (ATCC15834, C318, A13, 9453 and A4) were used by...
Vertebrate Hairy genes are highly pleiotropic and have been implicated in numerous functions, such as somitogenesis, neurogenesis and endocrine tissue development. In order to gain insight into the timing of acquisition of these roles by the Hairy subfamily, we have cloned and studied the expression pattern of the Hairy gene(s) in amphioxus. The cephalochordate amphioxus is widely believed to b...
The BRAF-V600E mutation defines genetically hairy cell leukemia among B-cell leukemias and lymphomas. In solid tumors, BRAF-V600E is known to aberrantly activate the oncogenic MEK-ERK pathway, and targeted BRAF and/or MEK inhibitors have shown remarkable efficacy in clinical trials in melanoma patients. However, the MEK-ERK pathway status in hairy cell leukemia has not been thoroughly investiga...
Most cases of hairy cell leukemia represent malignancies of B cells. However, recent findings suggest that there is a spectrum of functional capacities within the entity hairy cell leukemia. Two patients with hairy cell leukemia, whose malignant cells in the peripheral blood showed both T- and B-cell features, are reported. The malignant cells of the spleens showed only B-cell characteristics. ...
Hairy cell leukemia (HCL) is a relatively rare, chronic B-cell lymphoproliferative disorder characterized by splenomegaly, pancytopenia and bone marrow infiltration by hairy cells with circumferential prominent hairy cytoplasmic projections. Splenomegaly with few atypical lymphoid cells in peripheral blood lead to the examination of bone marrow for morphological findings characteristic of hairy...
Hairy cell leukaemia variant is a very rare chronic lymphoproliferative disorder and is closely related to hairy cell leukemia. We hereby describe a case of hairy cell leukaemia variant for the first time in Saudi Arabia. An elderly Saudi man presented with pallor, massive splenomegaly, and moderate hepatomegaly. Hemoglobin was 7.7 g/dl, Platelets were 134 x109/l and white blood count was 140x1...
This study evaluated the induction of hairy roots in Perovskia abrotanoides Karel, a medicinally important member of Lamiaceae family, using different strains of Agrobacterium rhizogenes and various carbon supplies, for the first time. This research established an efficient Agrobacterium mediated transformation system for this plant species through bacterial strains including ATCC15834, TR105 a...
Soybean hairy roots transformed with the resveratrol synthase and resveratrol oxymethyl transferase genes driven by constitutive Arabidopsis actin and CsVMV promoters were characterized. Transformed hairy roots accumulated glycoside conjugates of the stilbenic compound resveratrol and the related compound pterostilbene, which are normally not synthesized by soybean plants. Expression of the non...
High stability of the production of secondary metabolites is an interesting characteristic of hairy root cultures. For 25 years, hairy roots have been investigated as a biological system for the production of valuable compounds from medicinal plants. A better understanding of the molecular mechanism of hairy root development, which is based on the transfer of Agrobacterium rhizogenes T-DNA into...
Background: Trigonella foenum-graecum L. commonly known as fenugreek is a rich source of important medicinal metabolite, i.e. trigonelline. Objective: In this study, hairy roots culture as a novel method for trigonelline production was evaluated. Methods: For optimizing the hairy roots culture of Trigonella foenum-graecum, three strains of Agrobacterium rhyzogenes (ATCC15834, MSU440 and K...
