The present study describes a technique for quantitation of mRNA in a few isotypic cells obtained from an intact organ structure by combining laser-assisted cell picking and real-time PCR. The microscopically controlled lasering of selected cells in stained tissue sections was applied to lung alveolar macrophages, which are unique in that they can(More)
The excitability of pulmonary artery smooth muscle cells (PASMC) is regulated by potassium (K+) conductances. Although studies suggest that background K+ currents carried by 2-pore domain K+ channels are important regulators of resting membrane potential in PASMC, their role in human PASMC is unknown. Our study tested the hypothesis that TASK-1 leak K+(More)
The human neutrophil NB1 glycoprotein (NB1 GP, HNA-2a, CD177) has gained clinical importance for being involved in pulmonary transfusion reactions and immune neutropenias. The NB1 GP shows the unique feature of being expressed only on a neutrophil subpopulation. Recently, we identified splicing defects responsible for an NB1 GP deficiency. In this study, we(More)
Infertile men exhibit an aberrant protamine-1 (Prm1) to protamine-2 (Prm2) ratio at both the mRNA and protein level. We therefore investigated whether male infertility could be related to the amount of Prm1 and Prm2 mRNA by applying real time quantitative PCR following RNA extraction from routinely Bouin-fixed and paraffin-embedded testicular biopsies.(More)
Carcinoma in situ (CIS) represents the preinvasive stage of human germ cell tumors, but the mechanism leading to pubertal proliferation and invasive malignancy remains unknown. Among testicular gap junctional proteins, connexin 43 (Cx43) represents the predominant Cx, and, previously, an inverse correlation between synthesis of Cx43 protein and progression(More)
PURPOSE Transient elastography (FibroScan, [TE]) and serum fibrosis markers such as the FibroTest (FT) are established methods for the noninvasive staging of liver fibrosis. A study using real-time elastography (HI-RTE), which is integrated in a conventional ultrasound system, was recently published with comparable results to transient elastography. The aim(More)

Systemic vasculitides constitute a heterogeneous group of diseases. Autoimmunity mediated by B lymphocytes and their humoral effector mechanisms play a major role in ANCA-associated vasculitis (AAV) as well as in non-ANCA associated primary systemic vasculitides and in the different types of autoimmune connective tissue disorders and rheumatoid arthritis.(More)
Smoking is the most important risk factor for both lung cancer (LC) and chronic obstructive pulmonary disease. The aim of this study was to investigate the role of myeloid cell nuclear factor-κB in the regulation of tumor cell growth signaling. We subjected mice lacking myeloid RelA/p65 (relaΔ−/−) to a metastatic LC model. Cigarette smoke (CS) exposure(More)
The receptor activator of NF-κB (RANK), its ligand (RANKL) and osteoprotegerin (OPG) have been reported to play a role in the pathophysiological bone turnover and in the pathogenesis of breast cancer. Based on this we investigated the role of single nucleotide polymorphisms (SNPs) within RANK, RANKL and OPG and their possible association to breast cancer(More)
