We investigated the role of lamin B2 in non-small cell lung cancer (NSCLC). We detected higher lamin B2 expression in 20 NSCLC tumor tissues obtained from The Cancer Genome Atlas than in adjacent normal lung tissues. LMNB2-RNAi knockdown in A549 and H1299 NSCLC cells inhibited colony formation, cell proliferation and G1-S cell cycle progression while increasing apoptosis. LMNB2 overexpression h...

Kaposi sarcoma (KS) is an angioproliferative tumor derived from endothelial cells in which tumor cells form aberrant vascular structures. Ephrin B2 and ephrin B4 (EphB4) are artery- and vein-specific proteins, respectively, with critical roles in vessel maturation. We investigated whether the disorganized KS vasculature was due to unbalanced expression of ephrin B2 and EphB4. Secondly, we wishe...

After the engagement of Ag receptor, most of the Th cells for their optimal activation require a second (costimulatory) signal provided by the APCs. We demonstrate the isolation and characterization of a 99- to 105-kDa protein (B2), from LPS-activated B cell surface, and its function as a Th2-specific costimulatory molecule. Appearance of B2 as a single entity on two-dimensional gel electrophor...

Molecular detection methods such as RT-PCR for detecting breast cancer-associated gene expression in the peripheral blood have the potential to modify breast cancer (BC) staging and therapy. In this regard, we evaluated the potential of erb-B2 molecular marker in BC detection and analyzed the expression of erb-B2 mRNA in the peripheral blood and fresh tissue samples of 50 pretreated female BC p...

cDNA clones containing sequence similarity to the multifunctional vertebrate protein disulfide-isomerase (PDI, EC 5.3.4.1) were isolated from an alfalfa (Medicago sativa L.) cDNA library by screening with a cDNA sequence encoding human PDI. The polypeptide encoded by a clone designated B2 consisted of 512 amino acids and was characterized by a 24-amino acid hydrophobic leader sequence, two regi...

Bone marrow samples from normal adults and children with nonhematologic malignancies not involving the marrow, acute lymphoblastic leukemia (ALL) in continued remission, and immune cytopenias were studied by two-color immunofluorescence (IF) and flow cytometry to characterize common acute lymphoblastic leukemia antigen (CALLA)-positive marrow lymphoid cells. Marrow was separated by Ficoll/Hypaq...

SIGNIFICANCE High-, long-, and triple-jump athletic events may need to consider whether it is appropriate group vision-impaired athletes in the same classification with loss of different visual functions, a greater emphasis be placed on field (VF) within current system used. PURPOSE Athletes vision impairment are grouped, based their function, into one three classes (B1, B2, B3, B1 being most s...
