Ionizing Radiation and Ultraviolet Light Irradiation‐Associated DNA Damage Increasing Genomic Instability Risk

open access: yesCancer Science, EarlyView.
UV irradiation induces two major types of pyrimidine dimers, CPDs and 6–4PPs. Whereas 6–4PPs efficiently induce cell‐cycle arrest, CPDs do not and frequently persist into S phase. As a result, DSBs can arise in the presence of unrepaired CPDs after 6–4PPs have been repaired, increasing the risk of genomic instability.

Clues of ancient incomplete lineage sorting during bivalve evolution undermine support for Heterodonta

open access: yesCladistics, EarlyView.
Abstract A long‐standing challenge in phylogenomics has been the resolution of relationships originated from ancient radiations. In these cases, phenomena such as incomplete lineage sorting can increase the support for conflicting resolutions. Most of the diversity in the Class Bivalvia originated during an Ordovician radiation; indeed, several deep ...

Macrophage Lipid Homeostasis Drives IVDD via a Senescence‐Dependent Impairment of Efferocytosis

open access: yesCell Proliferation, EarlyView.
Intervertebral disc degeneration (IVDD) has been a leading cause of low back pain and lacks disease‐modifying therapies. Although dysregulated disc lipid metabolism is implicated, its impact on the immune microenvironment, particularly macrophages, remains unknown.

GCN2 in proteostasis: structural logic, signalling networks and disease

open access: yesThe FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.

Transgenic selection and underlying mechanisms in apicomplexan parasites

open access: yesThe FEBS Journal, EarlyView.
Transgenic selection markers have driven genetic engineering in apicomplexans, enabling precise, iterative experiments. This review discusses mechanistic details of drug selection markers, strategies for marker recycling, and practical considerations for several clinically relevant parasites.

RNF13 regulates the endolysosomal pathway through interaction with the small GTPase Arl8B

open access: yesThe FEBS Journal, EarlyView.
The E3 ubiquitin ligase RNF13 functions as a regulatory scaffold, organizing Arl8B‐dependent complexes and tuning downstream signaling that controls endolysosomal organization and trafficking. In this model, wild‐type RNF13 associates with Arl8B on endolysosomes, whereas Arl8B (E22D/F55A) or RNF13 (L244A) variants weaken complex assembly, potentially ...
