چکیده

Cytokeratin 1, an intermediate filament keratin, was isolated as a partner of the tyrosine kinase Src from neuroblastoma NMB7 cells. The cytokeratin 1-Src complex was found to be associated with the molecular scaffolder RACK1 (receptor for activated protein kinase C). Interestingly, the cytokeratin 1-Src-RACK1 complex was found to actively bind with membrane receptors such as integrin beta1. We are interested in using this complex to find downstream kinases and phosphatases that bind upon cytokine stimulation, especially during neurogenesis.

Retroperitoneal Anaplastic Neuroblastoma in a 3-Year-Old Female: A Rare Case Report

Neuroblastoma is the most common extracranial solid tumor in childhood. In different classification of neuroblastomas, a subset of undifferentiated or poorly differentiated tumors with bizarre histological features has been mentioned. A 3-year-old girl presented with abdominal pain. Her haematological and biochemical parameters were normal except her urinary vanelylmandelic acid level was elevat...

Overexpression of the integrin-linked kinase mesenchymally transforms mammary epithelial cells.

Signals generated by the interaction of beta1 integrins with laminin in the basement membrane contribute to mammary epithelial cell morphogenesis and differentiation. The integrin-linked kinase (ILK) is one of the signaling moieties that associates with the cytoplasmic domain of beta1 integrin subunits with some specificity. Forced expression of a dominant negative, kinase-dead form of ILK subt...

The spatial relationship between stem cells and their progeny in the basal layer of human epidermis: a new view based on whole-mount labelling and lineage analysis.

In order to examine the spatial organisation of stem cells and their progeny in human epidermis, we developed a method for whole-mount epidermal immunofluorescence labelling using high surface beta1 integrin expression as a stem cell marker. We confirmed that there are clusters of high beta1 integrin-expressing cells at the tips of the dermal papillae in epidermis from several body sites, where...

Dystrophin Dp71f associates with the beta1-integrin adhesion complex to modulate PC12 cell adhesion.

Dystrophin Dp71 is the main product of the Duchenne muscular dystrophy gene in the brain; however, its function is unknown. To study the role of Dp71 in neuronal cells, we previously generated by antisense treatment PC12 neuronal cell clones with decreased Dp71 expression (antisense-Dp71 cells). PC12 cells express two different splicing isoforms of Dp71, a cytoplasmic variant called Dp71f and a...

Distinct ErbB2 receptor populations differentially interact with beta1 integrin in breast cancer cell models

ErbB2 is a member of the ErbB family of tyrosine kinase receptors that plays a major role in breast cancer progression. Located at the plasma membrane, ErbB2 forms large clusters in spite of the presence of growth factors. Beta1 integrin, membrane receptor of extracellular matrix proteins, regulates adhesion, migration and invasiveness of breast cancer cells. Physical interaction between beta1 ...
