Export of honeybee prepromelittin in Escherichia coli depends on the membrane potential but does not depend on proteins secA and secY [PDF]

open access: yes, 1989
Honeybee prepromelittin (70 amino acid residues), the precursor of an eukaryotic secretory protein, and a hybrid protein between prepromelittin and mouse dihydrofolate reductase (257 amino acid residues) were expressed in Escherichia coli and ...

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 ...

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 ...

A Unifying Scenario on the Origin and Evolution of Cellular and Viral Domains [PDF]

open access: yes, 2009
The cellular theory on the nature of life has been one of the first major advancements in biology. Viruses, however, are the most abundant life forms, and their exclusion from mainstream biology and the Tree of Life (TOL) is a major paradox in biology ...

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

Crosstalk between ubiquitination and translation in neurodevelopmental disorders

open access: yesFrontiers in Molecular Neuroscience
Ubiquitination is one of the most conserved post-translational modifications and together with mRNA translation contributes to cellular protein homeostasis (proteostasis).

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.

Rippling life on a dormant planet: hibernation of ribosomes, RNA polymerases, and other essential enzymes

open access: yesFrontiers in Microbiology
Throughout the tree of life, cells and organisms enter states of dormancy or hibernation as a key feature of their biology: from a bacterium arresting its growth in response to starvation, to a plant seed anticipating placement in fertile ground, to a ...
