ALK IHC and FISH discordant results in patients with NSCLC and treatment response: for discussion of the question-to treat or not to treat?

Introduction: Lung cancer is the most common cancer worldwide. Latest guidelines from the College of American Pathologist and the European society of medical oncologists indicate anaplastic lymphoma kinase (ALK) rearrangement testing is standard practice. Historically, diagnostics for ALK used fluorescence in situ hybridisation (FISH); however, immunohistochemical (IHC) assays are becoming common practice.

Developmental expression of the 84-kDa ODF sperm protein: localization to both the cortex and medulla of outer dense fibers and to the connecting piece.

Outer dense fibers (ODF) are specialized cytoskeletal elements of the mammalian sperm tail which are composed of several prominent proteins. We previously reported the isolation of a cDNA (111-450) encoding a putative 84-kDa ODF protein. Here we demonstrate by independent cDNA isolations and by translational/immunoprecipitation of testicular mRNAs using anti-ODF 84 antibodies that 111-450 cDNA encodes the 84-kDa protein.

Interactional cloning of the 84-kDa major outer dense fiber protein Odf84. Leucine zippers mediate associations of Odf84 and Odf27.

The study of mammalian sperm tail outer dense fibers (ODF), a structure of unknown function, is hampered by the insoluble nature of ODF proteins and the availability of only one cloned component, Odf27. We report here the first use of the Odf27 leucine zipper as bait in a yeast two-hybrid screen to isolate a novel testis-specific protein whose interaction with Odf27 depends critically on the Odf27 leucine zipper. We find that the novel gene, 111-450, encodes a product that localizes to ODF as determined by fluorescence microscopy and immunoelectron microscopy and that the gene 111-450 product is identical to the major ODF protein, Odf84.

Pregnancy and birth after intracytoplasmic sperm injection with spermatozoa from a patient with tail stump syndrome.

Tail stump syndrome, which may be associated with primary ciliary dyskinesia, is also associated with morphological defects of the flagellum resulting in severe asthenozoospermia. Until recently, these morphological anomalies caused definite male infertility. Today, however, new methods such as micromanipulation techniques provide a rational therapy for this patient group.
