Type I Interferon Pathway Activation Disrupts Monocyte Maturation and Enhances Immune Evasion in Multiple Myeloma

open access: yesAdvanced Science, EarlyView.
This study shows that monocytes in multiple myeloma display an excessive interferon response, leading to transcriptional reprogramming and altered differentiation. Using single‐cell sequencing, coculture experiments, and patient samples before and after therapy, the authors demonstrate that induction treatment reduces this interferon response ...

Identification of the prebiotic translation apparatus within the contemporary ribosome [PDF]

open access: yes, 2009
A structural element that could have existed independently in the prebiotic era was identified at the active site of the contemporary ribosome. It is suggested to have functioned as a proto-ribosome catalyzing peptide bond formation and non-coded ...

Spatial and temporal distribution of ribosomes in single cells reveals aging differences between old and new daughters of Escherichia coli

open access: yeseLife
Lineages of rod-shaped bacteria such as Escherichia coli exhibit a temporal decline in elongation rate in a manner comparable to cellular or biological aging.

Red Blood Cells Internalize Extracellular DNA via Apoptotic Bodies with Clinical Relevance to Cancer Patients

open access: yesAdvanced Science, EarlyView.
Mature red blood cells (RBCs) can capture extracellular DNA, with short fragments homologous to cfDNA. This uptake is mediated by apoptotic bodies, which induce RBC oxidative stress, deformation, and accelerated in vivo clearance. The rbcDNA abundance correlates with tumor burden and therapeutic response, highlighting its potential as a liquid biopsy ...

Role of the Mitochondrial Genome During Early Development in Mice [PDF]

open access: yes, 1973
The role of the mitochondrial genome in early development and differentiation was studied in mouse embryos cultured in vitro from the two to four cell stage to the blastocyst (about 100 cells).

Chronic ER Stress Triggers Cell‐Surface Chaperones as the Therapeutic Targets of CAR Cells in Acute Myeloid Leukemia

open access: yesAdvanced Science, EarlyView.
Acute myeloid leukemia (AML) remains a therapeutic challenge due to its heterogeneity and limited targets. Here, multi‐omics analyses are utilized, and it is revealed that AML cells, particularly the FLT3‐ITD+ subtype, undergo chaperone‐mediated ER stress, inducing surface translocation of ER chaperones.

Proteogenomic Characterization Reveals Metabolic Vulnerabilities and Aberrant Phosphorylation in Colorectal Metastasis to Liver

open access: yesAdvanced Science, EarlyView.
This study provides a multi‐omics landscape of treatment‐naïve colorectal liver metastasis and reveals dysregulated molecules and cellular pathways. SHMT1 and NDRG1 Ser330 phosphorylation are demonstrated to display crucial roles in tumorigenesis and liver metastasis. Two proteomics subtypes (metabolism and RNA function) with distinct clinical outcomes

The ribosome-associated quality control pathway supports survival in the absence of non-stop ribosome rescue factors

open access: yesmBio
In bacteria, if a ribosome translates an mRNA lacking a stop codon it becomes stalled at the 3′ end of the message. These ribosomes must be rescued by trans-translation or the alternative rescue factors (ArfA or ArfB). However, mounting evidence suggests

ALDOA‐Mediated Metabolic Reprogramming is a Targetable Vulnerability for Ferroptosis Sensitization in Cancer

open access: yesAdvanced Science, EarlyView.
ALDOA‐depletion‐mediated glycolytic reprogramming promotes autophagy‐mediated degradation of MBOAT2, increasing the ratio of phospholipids containing pro‐ferroptotic polyunsaturated fatty acids over anti‐ferroptotic monounsaturated fatty acids, and thus sensitizing cancer cells to ferroptosis.

METTL5 Enables Immune Evasion of Liver Cancer via Chemokine mRNA Translation Regulation

open access: yesAdvanced Science, EarlyView.
METTL5 reshapes the tumor immune microenvironment through ribosome 18S rRNA m6A modification to regulate the translation of chemokine mRNA. Targeting METTL5‐mediated immunosuppression unleashes anti‐tumor immunity and improves the efficacy of anti‐PD‐1 therapy.
