Redox-signalling and antimicrobial peptides

Plants are permanently exposed to a great variety of microorganisms, such as viruses, mycoplasma, bacteria and fungi. However, similar to animals, plants possess an innate immune system. Redox molecules, such as nitric oxide or reactive oxygen species, and antimicrobial peptides, are important elements of this defense system to fight against pathogens and pests.

Ageing....is it inevitable?

Unfortunately yes it is....

But ageing Poorly is not.

Take a look at this short 2 minute video and make your own judgement.

Open PhD position

Our laboratory at the German Cancer Research Center (DKFZ) in Heidelberg, Germany,
is interested in the role of redox signaling and protein redox regulation in tumor cells
(for more information seehttp://www.dkfz.de/en/redoxregulation/).

The PhD position will be part of the newly established Collaborative Research Center (Sonderforschungsbereich, SFB) “Cellular surveillance and damage
 response” (see http://www.zmbh.uni-heidelberg.de/sfb1036/).

The project ‘Thiol peroxidases as sensors and transmitters of cytoprotective peroxide signals’ will address the role of thiol peroxidases in transcription factor regulation. We employ a broad range of techniques, ranging from Molecular Biology and Biochemistry (redox-dependent protein-protein interactions) to Cell Biology (live-cell imaging) and in vivo studies (transgenic mice).

We are an English-speaking, international laboratory with a friendly and productive work atmosphere and state-of-the-art equipment, located in Germany’s largest biomedical research institute. Successful candidates will enter the Helmholtz International Graduate School for Cancer Research.

Applicants must have a Master degree or equivalent in Biology, Biochemistry or related fields. Candidates should have a strong background in Biochemistry, Molecular Biology and/or Cell Biology. We expect excellent communication skills in English and enthusiasm for science.

Applications must include a cover letter, CV, copies of high school and university exams, and two letters of reference. Please send your application as one pdf file to t.dick@dkfz.de.

Signaling mechanisms integrating carbon and nitrogen utilization in plants

Abstract

Carbon (C) and nitrogen (N) are two essential nutrients affecting plant growth and development. Plants are non-motile organisms and have evolved highly sophisticated and complex sensing and signaling mechanisms to respond to the dynamic changes of C and N nutrients in their surroundings. C and N metabolism are tightly coordinated to maintain intracellular C/N homeostasis. However, the regulatory mechanism underlying C/N coordination and balancing in plants remains to be elucidated. It has been suggested that C and N metabolism are modulated by the interaction of C signaling with N signaling or by C/N ratio signaling. This review focuses on cell signaling studies that provide insight into the regulation mechanism of C/N balancing in plants.

Hydrogen sulfide anion regulates redox signaling via electrophile sulfhydration

An emerging aspect of redox signaling is the pathway mediated by electrophilic byproducts, such as nitrated cyclic nucleotide (for example, 8-nitroguanosine 3′,5′-cyclic monophosphate (8-nitro-cGMP)) and nitro or keto derivatives of unsaturated fatty acids, generated via reactions of inflammation-related enzymes, reactive oxygen species, nitric oxide and secondary products.

Redox Signaling in Adult Stem Cell Biology

Indeed, consolidated evidences highlight the importance of redox signalling in the homeostasis of fundamental processes in cell adaptive biology and particularly in controlling the balance between self-renewal and differentiation of stem cells.

In the presented study we investigated the effect of DFX and DFO on the redox homeostasis of hematopoietic stem/progenitor cells (HSPCs) in order to get insights on the differential effect of iron chelators in rescuing altered hematopoiesis.

Redox signaling, mediated by ROS production and likely triggered by changes in the environmental oxygen tension, appears to be essential in regulating HSC self-renewal and preservation of pluripotency
