Amyotrophic Lateral Sclerosis is characterized by TDP-43 proteinopathy in the brain. Here, the authors find TDP-43 aggregation might be mediated by the loss of Asparaginase-like 1, an enzyme that degrades detrimental isoaspartates and is downregulated by the endogenous retrovirus HML-2.

R-loop accumulation at transcription sites poses a persistent threat to genome integrity. Here the authors demonstrate a role for PSIP1/LEDGF protein in reducing R-loop levels at the site of transcription and preventing transcription replication conflict to maintain genome integrity.

mTOR signalling both inhibits autophagy and promotes cell proliferation. Cecconi and colleagues report that AMBRA1 links these two processes by facilitating dephosphorylation and degradation of the proto-oncogene c-Myc.

Glycosylation of human IgG antibodies in bacterial hosts has proven challenging. Here, the authors identify a bacterial enzyme enabling E. coli to glycosylate IgGs at native sites, thereby advancing therapeutic antibody development in this host.

DNA interstrand crosslinks induced by acetaldehyde are repaired by both the Fanconi anaemia pathway and by a second, excision-independent repair mechanism.

The benefit of regular exercise on the heart has been well documented but the role of RNA m⁶A modification in exercise-induced cardiac remodelling remains largely unknown. In this study, the authors report that METTL14 plays an important role in RNA m⁶A modification in exercise-induced physiological cardiac hypertrophy.

Hutchinson-Gilford Progeria Syndrome is characterized by premature aging with cardiovascular disease being the main cause of death. Here the authors show that inhibition of the NAT10 enzyme enhances cardiac function and fitness, and reduces age-related phenotypes in a mouse model of premature aging.

The authors characterize SMCHD1 as a nuclear lamina-associated protein in human myoblasts where it serves as an anchor for heterochromatin. Loss of SMCHD1 leads to B-to-A compartment transitions and numerous changes in 3D chromatin organization.

RNA circularization is vital for circRNA therapeutics. Here, authors present two in vitro methods—PIET and CIRC—where CIRC employs intact self-splicing introns to generate circRNAs efficiently, and enables large circRNA generation, broadening the circRNA platform’s potential.

The kinase Mst1, which acts in the Hippo pathway, controls cell proliferation, differentiation and apoptosis. Junichi Sadoshima and his colleagues show that Mst1 in cardiomyocytes phosphorylates the protein Beclin1 to coordinately suppress autophagy and promote apoptosis, thereby having deleterious effects on the heart.

Su et al. find that BACH1 specifically interacts with the p53 (R175H) hotspot mutant. This has double oncogenic effects, leading to increased expression of the pro-metastatic targets of BACH1 as well as blockage of its capacity to activate ferroptosis.

Small cell lung cancer presents high and multi-site metastatic potential. Here, the authors discover that FOXA2, regulated by ASCL1, promotes multi-site metastasis in small cell lung cancer by inducing a fetal neuroendocrine gene expression program.

Noncoding transcripts contribute to the adaptation of cellular processes to oxygen levels. Here the authors characterize a hypoxia responsive lncRNA lincNORS and show that it has a role in cellular sterol homeostasis.
