Prognostic and predictive role of gene mutations in chronic lymphocytic leukemia: results from the pivotal phase III study COMPLEMENT1.

Next generation sequencing studies in Chronic lymphocytic leukemia (CLL) have revealed novel genetic variants that have been associated with disease characteristics and outcome. The aim of this study was to evaluate the prognostic value of recurrent molecular abnormalities in patients with CLL. Therefore, we assessed their incidences and associations with other clinical and genetic markers in the prospective multicenter COMPLEMENT1 trial (treatment naive patients not eligible for intensive treatment randomized to chlorambucil (CHL) vs.

CONIFER - Non-Interventional Study to Evaluate Therapy Monitoring During Deferasirox Treatment of Iron Toxicity in Myelodysplastic Syndrome Patients with Transfusional Iron Overload.

Background: The non-interventional study CONIFER was designed to assess the safety and clinical practicability of deferasirox for the treatment of transfusional iron overload in myelodysplastic syndrome (MDS) patients.

Methods: Patients included in the study were diagnosed with MDS and received at least 1 treatment with deferasirox. The observation period covered the time from the initial visit until the last follow-up.

Angiogenin induces modifications in the astrocyte secretome: relevance to amyotrophic lateral sclerosis.

Unlabelled: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease affecting lower and upper motoneurons. Recent studies have shown that both motor neurons and non-neuronal neighbouring cells such as astrocytes and microglia contribute to disease pathology. Loss-of-function mutations in the angiogenin (ANG) gene have been identified in ALS patients.

Motoneurons secrete angiogenin to induce RNA cleavage in astroglia.

Amyotrophic lateral sclerosis (ALS) is an incurable neurodegenerative disorder affecting motoneurons. Mutations in angiogenin, encoding a member of the pancreatic RNase A superfamily, segregate with ALS. We previously demonstrated that angiogenin administration shows promise as a neuroprotective therapeutic in studies using transgenic ALS mice and primary motoneuron cultures.

Successful expansion but not complete restriction of tropism of adeno-associated virus by in vivo biopanning of random virus display peptide libraries.

Targeting viral vectors to certain tissues in vivo has been a major challenge in gene therapy. Cell type-directed vector capsids can be selected from random peptide libraries displayed on viral capsids in vitro but so far this system could not easily be translated to in vivo applications. Using a novel, PCR-based amplification protocol for peptide libraries displayed on adeno-associated virus (AAV), we selected vectors for optimized transduction of primary tumor cells in vitro.
