Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

TopBP1 utilises a bipartite GINS binding mode to support genome replication

Nature Communications
Activation of the replicative Mcm2-7 helicase by loading GINS and Cdc45 is crucial for replication origin firing, and as such for faithful genetic inheritance.

Radiation induced DNA damage responses [PDF]

, 2006
The amazing feature of ionising radiation (IR) as a DNA damaging agent is the range of lesions it induces. Such lesions include base damage, single strand breaks (SSBs), double strand breaks (DSBs) of varying complexity and DNA cross links.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Centromere protection requires strict mitotic inactivation of the Bloom syndrome helicase complex

Nature Communications
The BTRR (BLM/TOP3A/RMI1/RMI2) complex resolves DNA replication and recombination intermediates to maintain genome stability. Alongside PICH, they target mitotic DNA intertwinements, known as ultrafine DNA bridges, facilitating chromosome segregation ...

Xeroderma Pigmentosum Group C Deficiency Alters Cigarette Smoke DNA Damage Cell Fate and Accelerates Emphysema Development [PDF]

, 2018
Cigarette smoke (CS) exposure is a major risk factor for the development of emphysema, a common disease characterized by loss of cells comprising the lung parenchyma.

Cis‐regulatory and long noncoding RNA alterations in breast cancer – current insights, biomarker utility, and the critical need for functional validation

Molecular Oncology, EarlyView.
The noncoding region of the genome plays a key role in regulating gene expression, and mutations within these regions are capable of altering it. Researchers have identified multiple functional noncoding mutations associated with increased cancer risk in the genome of breast cancer patients.

CAS9 is a genome mutator by directly disrupting DNA-PK dependent DNA repair pathway. [PDF]

, 2020
With its high efficiency for site-specific genome editing and easy manipulation, the clustered regularly interspaced short palindromic repeats (CRISPR)/ CRISPR associated protein 9 (CAS9) system has become the most widely used gene editing technology in ...

Risks from low dose/dose rate radiation: what an understanding of DNA damage response mechanisms can tell us [PDF]

, 2009
The DNA damage response (DDR) mechanisms represent a vital line of defense against exogenous and endogenous DNA damage to enhance two distinct outcomes, survival and the maintenance of genomic stability. The latter is critical for cancer avoidance.
