Madelon small

Madelon Maurice has received a prestigious VICI grant from NWO. Title: Controlling the controller: Regulation of signals that guide stem and cancer cell growth and differentiation. Stem cell-mediated tissue renewal is precisely controlled by signals from the environment. These signals are often misused by cancer cells. Madelon aims to understand how stem cells capture and process these signals in order to better intervene in these processes in tissue repair and cancer.

29/08/14: VENI grant to Jorg van Loosdregt

Jorg van Loosdregt

Autophagy is a process that is switched on if there are insufficient nutrients and it is important for various cellular functions. The research supported by this grant will study how autophagy affects the immune system. Autophagy-manipulation could help to control autoimmune diseases such as (juvenile) arthritis.

01/12/2013: Anton Martens and Richard Groen from our department received a prestigeous grant from the Leukemia and Lymphoma Society (LLS) in the Quest for Cures program 2013.

AntonMartens kleinThe focus of their project is on the application of a novel in vitro and in vivo humanized engineered BCP scaffold-based bone marrow-like model to study multiple myeloma (MM) and acute leukemia (AML). It will be used to determine the patterns of sensitivity versus resistance to established and investigational therapies in this system, and to characterize the mechanisms whereby the humanized microenvironment alters tumor cell responses to these agents. The grant of in total $ 800,000 is for two years of research and will be carried out in the UMCU and in collaboration with Constantine Mitsiades from the Dana Farber Cancer Institute, Boston USA (November 2013)

Twenty early-career scientists are selected each year to participate in this rigorous training program, which provides junior researchers with a unique, year-long training and mentoring experience. The TRTH faculty is made up of international leaders in hematology who cover biostatistics and biomarkers, genetics and molecular biology, ethics, and phase I clinical study design.

 

01/11/2013: International foundation for Alzheimer research (ISAO) grant to Judith Klumperman

Judith newJudith Klumperman was awarded the ISAO grant for the project 'Targeting lysosomal enzyme activity in Alzheimer Disease'. A hallmark of dystrophic neurons of Alzheimer's Disease (AD) patients is the massive accumulation of dysfunctional endo-lysosomal compartments. Impaired endo-lysosomal proteolysis starts early in the development in AD and is an important cause of Ab accumulation and progression of cellular pathologies. This projects aims to understand the contribution of the endo-lysosomal system to AD development and find tools to alleviate AD-induced defects of endo-lysosomal functioning. 

 

07/10/2013: The 2013 Nobel Prize in Physiology or Medicine has been awarded to Randy Schekman , Jim Rothman , and Tom Südhof  in recognition of their breakthrough experiments on vesicle transport mechanisms.

Work on how cargoes are transported through cells traces back to previous Nobel winners George Palade, Albert Claude, Christian de Duve  and Günther Blobel (1999). The development of electron microscopy and cell fractionation techniques by Palade, Claude and de Duve paved the way for their discoveries of such subcellular organelles/structures as endoplasmic reticulum, lysosomes, and ribosomes as well as the assembly of secretory proteins. Blobel brought the field to the next level by uncovering a bar code on newly synthesized proteins and the characterization of the barcode reader that is required for their targeting and delivery to the correct intracellular compartment.

An initially controversial hypothesis held that newly synthesized secretory proteins are transported in discrete quanta — in vesicular carriers that bud from a donor membrane and deliver their contents by fusion with a target membrane. The principles for incorporating proteins in vesicular carriers were amongst others elucidated by Nobel laureates Mike Brown and Joe Goldstein when analyzing how LDL-associated cholesterol entered the cell.

The molecular rules for generating transport vesicles, their journey through the cytoplasm and fusion with a target organelle were however totally unknown. Randy Schekman and Jim Rothman, both deeply influenced by the reconstitution paradigm of Arthur Kornberg, entered the field in the late seventies and brought our understanding of vesicle traffic from a merely descriptive level to the beginning of a mechanistic understanding.

Schekman used forward genetics in budding yeast to define the trafficking pathways in this organism and characterize a large collection of so called SEC mutants that block vesicular traffic between different compartments. Rothman took on the daunting task of developing a biochemical in vitro assay for reconstituting glycoprotein transport through the Golgi complex in a test tube. With progressively increasing sophistications, he succeeded in purifying and cloning proteins that enabled vesicles to dock and fuse with target membranes. In the fusion reaction, proteins on the vesicles and target membranes bind to each other like the two sides of a zipper. Several of the genes Schekman had discovered in yeast encoded proteins corresponding to those Rothman identified in mammals, revealing an ancient evolutionary origin of the transport system. Collectively, they mapped critical components of the cell´s transport machinery for which they received the Lasker award in 2002.

Südhof investigated how nerve cells communicate with each other in the brain. They do so by releasing neurotransmitter from synaptic vesicles that fuse with the membrane of neurons using the proteins discovered by Rothman and Schekman. Synaptic vesicles should only release content during neuronal signaling, a process controlled by calcium ions. Südhof discovered calcium-sensitive proteins in neurons and the molecular machinery that responds to an influx of calcium ions. These proteins mediate rapid binding of vesicles to the cell surface of the nerve cell and open up the zippers that Rothman identified before, allowing for neurotransmitter release. Südhof´s discovery explained how temporal precision is achieved and how vesicle contents are released on command. He received the Lasker award together with Richard Scheller in September 2013, merely one month prior to the Nobel Prize.
