Daily full spectrum light exposure prevents food allergy-like allergic diarrhea by modulating vitamin D and microbiota composition.

NPJ Biofilms Microbiomes 2021 May 6;7(1):41. Epub 2021 May 6.

Liver Transplantation Center, Kaohsiung Chang Gung Memorial Hospital, Kaohsiung, Taiwan.

The importance of sun exposure on human health is well recognized, and a recent trend in the avoidance of sun exposure has led to the risk of missing the beneficial effects such as vitamin D biogenesis. Vitamin D insufficiency is one of the risk factors for the development of food allergies (FAs), and vitamin D status controls gut homeostasis by modulating the microbiota. This study aimed to explore the impact of daily full spectrum light exposure (phototherapy) on the pathogenesis of FAs. Read More

Fanconi anemia and the underlying causes of genomic instability.

Environ Mol Mutagen 2020 08 6;61(7):693-708. Epub 2020 Feb 6.

Department of Pharmacological Sciences, State University of New York at Stony Brook, Stony Brook, New York.

Fanconi anemia (FA) is a rare genetic disorder, characterized by birth defects, progressive bone marrow failure, and a predisposition to cancer. This devastating disease is caused by germline mutations in any one of the 22 known FA genes, where the gene products are primarily responsible for the resolution of DNA interstrand cross-links (ICLs), a type of DNA damage generally formed by cytotoxic chemotherapeutic agents. However, the identity of endogenous mutagens that generate DNA ICLs remains largely elusive. Read More

Structure of the Fanconi anaemia monoubiquitin ligase complex.

Nature 2019 11 30;575(7781):234-237. Epub 2019 Oct 30.

MRC Laboratory of Molecular Biology, Cambridge, UK.

The Fanconi anaemia (FA) pathway repairs DNA damage caused by endogenous and chemotherapy-induced DNA crosslinks, and responds to replication stress. Genetic inactivation of this pathway by mutation of genes encoding FA complementation group (FANC) proteins impairs development, prevents blood production and promotes cancer. The key molecular step in the FA pathway is the monoubiquitination of a pseudosymmetric heterodimer of FANCD2-FANCI by the FA core complex-a megadalton multiprotein E3 ubiquitin ligase. Read More

Reduced fractional anisotropy in depressed patients due to childhood maltreatment rather than diagnosis.

Neuropsychopharmacology 2019 11 5;44(12):2065-2072. Epub 2019 Aug 5.

Department of Psychiatry, University of Münster, Münster, Germany.

Reduced fractional anisotropy (FA) associated with Major Depressive Disorder (MDD) overlaps anatomically with effects of childhood maltreatment experiences. The aim of this study was, therefore, to replicate the negative effect of childhood maltreatment on white matter fiber structure and to demonstrate, that alterations in MDD might be partially attributed to the higher occurrence of childhood maltreatment in MDD. Two independent cohorts (total N = 1 256) were investigated in a diffusion tensor imaging study: The Münster Neuroimaging Cohort (MNC, N = 186 MDD, N = 210 healthy controls, HC) as discovery sample and the Marburg-Münster Affective Disorders Cohort Study (MACS, N = 397 MDD, N = 462 HC) as replication sample.

The Fanconi Anemia Pathway in Cancer.

Annu Rev Cancer Biol 2019 Mar 3;3:457-478. Epub 2018 Dec 3.

Department of Radiation Oncology and Center for DNA Damage and Repair, Dana-Farber Cancer Institute, Boston, Massachusetts 02215, USA;

Fanconi anemia (FA) is a complex genetic disorder characterized by bone marrow failure (BMF), congenital defects, inability to repair DNA interstrand cross-links (ICLs), and cancer predisposition. FA presents two seemingly opposite characteristics: () massive cell death of the hematopoietic stem and progenitor cell (HSPC) compartment due to extensive genomic instability, leading to BMF, and () uncontrolled cell proliferation leading to FA-associated malignancies. The canonical function of the FA proteins is to collaborate with several other DNA repair proteins to eliminate clastogenic (chromosome-breaking) effects of DNA ICLs. Read More

Focal Adhesions Undergo Longitudinal Splitting into Fixed-Width Units.

Curr Biol 2018 07 14;28(13):2033-2045.e5. Epub 2018 Jun 14.

Department of Biochemistry and Cell Biology, Geisel School of Medicine at Dartmouth, Hanover, NH 03755, USA. Electronic address:

Focal adhesions (FAs) and stress fibers (SFs) act in concert during cell motility and in response to the extracellular environment. Although the structures of mature FAs and SFs are well studied, less is known about how they assemble and mature de novo during initial cell spreading. In this study using live-cell Airyscan microscopy, we find that FAs undergo "splitting" during their assembly, in which the FA divides along its longitudinal axis. Read More

Conformational states during vinculin unlocking differentially regulate focal adhesion properties.

Sci Rep 2018 02 9;8(1):2693. Epub 2018 Feb 9.

Department of Molecular Cell Biology, Weizmann Institute of Science, Rehovot, 7610001, Israel.

Focal adhesions (FAs) are multi-protein complexes that connect the actin cytoskeleton to the extracellular matrix, via integrin receptors. The growth, stability and adhesive functionality of these structures are tightly regulated by mechanical stress, yet, despite the extensive characterization of the integrin adhesome, the detailed molecular mechanisms underlying FA mechanosensitivity are still unclear. Besides talin, another key candidate for regulating FA-associated mechanosensing, is vinculin, a prominent FA component, which possesses either closed ("auto-inhibited") or open ("active") conformation.
