Determination of T-cell clonality and expression profiles of Toll-like receptors signaling pathway genes and related miRNAs in patients with mycosis fungoides.

Cutaneous T-cell lymphomas (CTCL) encompass a group of diseases characterized by the presence of malignant clonal CD4+ T lymphocytes in the skin. Mycosis fungoides (MF) is the most prevalent form of CTCL, accounting for approximately 60 % of cutaneous T-cell lymphomas and 50 % of all primary cutaneous lymphomas. Despite ongoing research, the precise pathogenesis of MF remains incompletely understood.

Investigation of Immunovascular Polymorphisms and Intersections in Psoriasis.

Background: Psoriasis is a chronic, inflammatory skin disease. The etiology of the disease is unknown. It is a polygenic and multifactorial disease, which interacts with genetic and environmental factors.

Vitamin D receptor gene polymorphisms and haplotypes (Apa I, Bsm I, Fok I, Taq I) in Turkish psoriasis patients.

Background: Psoriasis is an inflammatory disease characterized by increased squamous cell proliferation and impaired differentiation. Vitamin D, Calcitriol, and its analogues are successfully used for psoriasis therapy. However, it is unknown why some psoriasis patients are resistant to Vitamin D therapy.

Tumour suppressor PTEN enhanced enzyme activity of GPx, SOD and catalase by suppression of PI3K/AKT pathway in non-small cell lung cancer cell lines.

Phosphates and tensin homologue deleted on chromosome 10 (PTEN) is a tumour suppressor gene which dephosphorilates phosphoinositol 3,4,5 triphosphates. Therefore PTEN can regulate PI3K/AKT pathway in cells. Because of promoter methylation or gene deletion, PTEN expression is commonly decreased or lost in non-small cell lung cancer (NSCLC) cell lines.

Is Helicobacter pylori a pathogenic agent of the cervix uteri?

Background: Helicobacter pylori is a gram-negative, microaerophilic rod-shaped bacterium that lives beneath the gastric mucosal layers, on the surface of epithelial cells. Gastric infection with this organism causes inflammation of the gastric mucosa, which can lead to gastritis, duodenal or gastric ulcers and even in rare cases to gastric carcinoma or MALT lymphoma. Approximately 50% of the population of the entire world is believed to be infected with H.

Existence of acute lymphoblastic leukemia and osteosarcoma in a child.

The existence of acute lymphoblastic leukemia (ALL) and osteosarcoma is described. An 8-year-old girl had osteosarcoma diagnosed on radiologic and pathologic examination during ALL maintenance treatment. Cytogenetic analyses in primary cell culture of osteosarcoma tissue from the patient showed complex chromosomal abnormalities including t(1;19), usually seen in B precursor cell ALL, and del 13, found in a great majority of primary osteosarcomas.

Incidence and molecular analysis of glucose-6-phosphate dehydrogenase deficiency in the province of Denizli, Turkey.

Background: G6PD deficiency is a widespread abnormality of glucose-6-phosphate dehydrogenase, a red cell enzyme, which gives rise to hemolysis under oxidative stress. In Turkey, G6PD deficiency has a variable frequency in different regions. The prevalence and genotypes of G6PD deficiency are not known in Denizli province of the Aegean region of Turkey.
