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 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...
background: hairy cell leukemia (hcl) is a chronic b-cell lymphoid leukemia characterized by pancytopenia, splenomegaly, myelofibrosis and the presence in peripheral blood, bone marrow and spleen of atypical lymphoid cells with a hairy aspect. the study aims to evaluate a group of patients with hairy cell leukemia, hospitalized in the clinic of hematology and oncology, kermanshah, iran, on a pe...
Hairy cell leukemia is an indolent, chronic B-cell lymphoproliferative disorder comprising approximately 2 to 3% of all adult leukemias in the United States. Hairy cells are clonal expansions of mature, activated B-cells. They co-express CD11c, CD19, CD20, CD22, CD25, and CD103. Hairy cells possess clonal immunoglobulin gene rearrangements and express monoclonal surface immunoglobulin of either...
Monoclonal antibodies reactive with hairy cell leukemia were developed to aid in the diagnosis of this subtype of B cell chronic lymphocytic leukemia and to gain better insight into the origin of hairy cells. Three antibodies were found to be of value in the diagnosis of hairy cell leukemia. Antibody B-ly 2 can be considered a pan-B cell reagent and generally reacts similar to CD22 antibodies. ...
background: plant cell cultivations are considered as an alternative to agricultural processes for producing valuable phytochemicals (secondary metabolites). the use of plant cell cultures has overcome several inconveniences for the production of secondary metabolites. objective: the essential oils isolated from roots of 24-month-old field grown valerian (valeriana sisymbriifolium) and hairy ro...
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...
Dear Editor-in-Chief A 28 yr male was presented in October 2015 at Medicine Outpatient Department, Safdarjung Hospital, New Delhi- India with generalized weakness, fever and cough for preceding 15 days. Clinicoradiologic examination revealed pallor, firm, non-tender splenomegaly measuring 13.7 cm and hepatomegaly (liver span - 16.9 cm). However, no lymphadenopathy was found.
this experiment was carried out to evaluations the allopathic foliar application of safflower)carthamus tintorius) aqueous extracts on growth and leaf cell membrane leakage of hairy vetech (vicia villosa). the experimental arrangement was crd in four replications. results showed that by increasing the concentration of safflower extracts, shoot dry weight and peroxidase enzyme activity decrease...
