Q: The pathogenicity of many bacteria depends on the injection of effector proteins via type III secretion into eukaryotic cells in order to manipulate cellular processes. TAL (transcription activator-like) effectors from plant pathogenic Xanthomonas are important virulence factors that act as transcriptional activators in the plant cell nucleus, where they directly bind to DNA via a central domain of tandem repeats. Here, we show how target DNA specificity of TAL effectors is encoded. Two hypervariable amino acid residues in each repeat recognize one base pair in the target DNA. Recognition sequences of TAL effectors were predicted and experimentally confirmed. The modular protein architecture enabled the construction of artificial effectors with new specificities. Our study describes the functionality of a distinct type of DNA binding domain and allows the design of DNA binding domains for biotechnology.

Q: Burns are one of the most devastating conditions encountered in medicine. The injury represents an assault on all aspects of the patient, from the physical to the psychological. It affects all ages, from babies to elderly people, and is a problem in both the developed and developing world. All of us have experienced the severe pain that even a small burn can bring. However the pain and distress caused by a large burn are not limited to the immediate event. The visible physical and the invisible psychological scars are long lasting and often lead to chronic disability. Burn injuries represent a diverse and varied challenge to medical and paramedical staff. Correct management requires a skilled multidisciplinary approach that addresses all the problems facing a burn patient. This series provides an overview of the most important aspects of burn injuries for hospital and non-hospital healthcare workers.workers.

Q: Methyl-CpG binding protein 1 (MBD1) regulates gene expression via a DNA methylation-mediated epigenetic mechanism. We have previously demonstrated that MBD1 deficiency impairs adult neural stem/progenitor cell (aNSC) differentiation and neurogenesis, but the underlying mechanism was unclear. Here, we show that MBD1 regulates the expression of several microRNAs in aNSCs and, specifically, that miR-184 is directly repressed by MBD1. High levels of miR-184 promoted proliferation but inhibited differentiation of aNSCs, whereas inhibition of miR-184 rescued the phenotypes associated with MBD1 deficiency. We further found that miR-184 regulates the expression of Numblike (Numbl), a known regulator of brain development, by binding to the 3'-UTR of Numbl mRNA and affecting its translation. Expression of exogenous Numbl could rescue the aNSC defects that result from either miR-184 overexpression or MBD1 deficiency. Therefore, MBD1, miR-184, and Numbl form a regulatory network that helps control the balance between proliferation and differentiation of aNSCs.

A:
Epigenetic regulation of miR-184 by MBD1 governs neural stem cell proliferation and differentiation.
