Nuclear cGAS: sequestration and beyond [PDF]
Protein & Cell, 2021 AbstractThe cyclic GMP-AMP (cGAMP) synthase (cGAS) has been identified as a cytosolic double stranded DNA sensor that plays a pivotal role in the type I interferon and inflammation responses via the STING-dependent signaling pathway. In the past several years, a growing body of evidence has revealed that cGAS is also localized in the nucleus where it ...

Virologica Sinica, 2018 The cGAS-MITA pathway of cytosolic DNA sensing plays essential roles in immune response against pathogens that contain DNA or with DNA production in their life cycles. The cGAS-MITA pathway also detects leaked or aberrant accumulated self DNA in the cytoplasm under certain pathological conditions, such as virus induced cell death, DNA damage ...

The multifaceted functions of cGAS
Journal of Molecular Cell Biology, 2022 Abstract Pattern recognition receptors are critical for the sensing of pathogen-associated molecular patterns or danger-associated molecular patterns and subsequent mounting of innate immunity and shaping of adaptive immunity. The identification of 2′3′-cyclic guanosine monophosphate–adenosine monophosphate (cGAMP) synthase (cGAS) as a ...

Nuclear cGAS: guard or prisoner? [PDF]
The EMBO Journal, 2021 cGAS, an innate immune sensor of cellular stress, recognizes double-stranded DNA mislocalized in the cytosol upon infection, mitochondrial stress, DNA damage, or malignancy. Early models suggested that cytosolic localization of cGAS prevents autoreactivity to nuclear and mitochondrial self-DNA, but this paradigm has shifted in light of recent findings ...

The many faces of cGAS: how cGAS activation is controlled in the cytosol, the nucleus, and during mitosis [PDF]
Signal Transduction and Targeted Therapy, 2021 Psychosocial stress is one of the main environmental factors contributing to the development of psychiatric disorders. In humans and rodents, chronic stress is associated with elevated inflammatory responses, indicated by increased numbers of circulating myeloid cells and activation of microglia, the brain-resident immune cells.

Barrier-to-autointegration factor 1 protects against a basal cGAS-STING response [PDF]
, 2020 Although the pathogen recognition receptor pathways that activate cell-intrinsic antiviral responses are well delineated, less is known about how the host regulates this response to prevent sustained signaling and possible immune-mediated damage. Using a

The cGAS Paradox: Contrasting Roles for cGAS-STING Pathway in Chromosomal Instability [PDF]
Cells, 2019 Chromosomal instability (CIN) is an intricate phenomenon that is often found in human cancer, characterized by persisting errors in chromosome segregation. This ongoing chromosome mis-segregation results in structural and numerical chromosomal abnormalities that have been widely described to promote tumor evolution.

Nonspecific DNA Binding of cGAS N Terminus Promotes cGAS Activation [PDF]
The Journal of Immunology, 2017 Abstract The cytosolic DNA sensor cyclic GMP-AMP synthase (cGAS) mediates innate immune responses against invading pathogens, or against self-dsDNA, which causes autoimmune disorders. Upon nonspecific binding of cytosolic B–form DNA, cGAS synthesizes the second messenger 2′3′-cGAMP and triggers STING-dependent signaling to produce type I

UHPLC-PDA-ESI-TOF/MS metabolic profiling and antioxidant capacity of arabica and robusta coffee silverskin: antioxidants vs phytotoxins [PDF]
, 2017 A deeper knowledge of the chemical composition of coffee silverskin (CS) is needed due to the growing interest in its use as a food additive or an ingredient of dietary supplements.

Cytoplasmic chromatin triggers inflammation in senescence and cancer [PDF]
, 2017 Chromatin is traditionally viewed as a nuclear entity that regulates gene expression and silencing. However, we recently discovered the presence of cytoplasmic chromatin fragments that pinch off from intact nuclei of primary cells during senescence, a ...
