Burden of dry eye disease in Germany: a retrospective observational study using German claims data.

Purpose: To evaluate the clinical and economic burden of dry eye disease (DED) among affected patients in Germany.

Methods: Adult patients (≥18 years) with ≥1 confirmed diagnosis of DED during the study period (2008-2015) were identified from the medical claims of ~3.6 million insured patients from Betriebskrankenkassen, a German statutory health insurance database.

Circulating APRIL levels are correlated with advanced disease and prognosis in rectal cancer patients.

We have previously shown that the tumor necrosis factor family member a proliferation-inducing ligand (APRIL) enhances intestinal tumor growth in various preclinical tumor models. Here, we have investigated whether APRIL serum levels at time of surgery predict survival in a large cohort of colorectal cancer (CRC) patients. We measured circulating APRIL levels in a cohort of CRC patients (n=432) using a novel validated monoclonal APRIL antibody (hAPRIL.

Tubulin glycylases are required for primary cilia, control of cell proliferation and tumor development in colon.

TTLL3 and TTLL8 are tubulin glycine ligases catalyzing posttranslational glycylation of microtubules. We show here for the first time that these enzymes are required for robust formation of primary cilia. We further discover the existence of primary cilia in colon and demonstrate that TTLL3 is the only glycylase in this organ.

Chronic lymphocytic leukemia disease progression is accelerated by APRIL-TACI interaction in the TCL1 transgenic mouse model.

Although in vitro studies pointed to the tumor necrosis factor family member APRIL (a proliferation-inducing ligand) in mediating survival of chronic lymphocytic leukemia (CLL) cells, clear evidence for a role in leukemogenesis and progression in CLL is lacking. APRIL significantly prolonged in vitro survival of CD5(+)B220(dull) leukemic cells derived from the murine Eμ-TCL1-Tg (TCL1-Tg [transgenic]) model for CLL. APRIL-TCL1 double-Tg mice showed a significantly earlier onset of leukemia and disruption of splenic architecture, and survival was significantly reduced.

The TNF family member APRIL promotes colorectal tumorigenesis.

The tumor necrosis factor (TNF) family member APRIL (A proliferation inducing ligand) is a disease promoter in B-cell malignancies. APRIL has also been associated with a wide range of solid malignancies, including colorectal cancer (CRC). As evidence for a supportive role of APRIL in solid tumor formation was still lacking, we studied the involvement of APRIL in CRC.

Therapy-resistant tumor microvascular endothelial cells contribute to treatment failure in glioblastoma multiforme.

Glioblastoma multiforme (GBM) is a devastating disease with high mortality and poor prognosis. Cancer stem cells (CSCs) have recently been defined as a fraction of tumor cells highly resistant to therapy and subsequently considered to be responsible for tumor recurrence. These cells have been characterized in GBM and suggested to reside in and be supported by the tumor microvascular niche.

Fusion of intestinal epithelial cells with bone marrow derived cells is dispensable for tissue homeostasis.

The epithelial lining of the intestine is characterized by an immense cellular turn-over ascertaining an extensive regenerative capacity. Multiple reports suggest that besides the local intestinal stem cell pool, circulating cells of bone marrow origin (BMDCs) contribute to this process by fusing with the epithelial lineage. However, the functional relevance of these observations is unknown.
