Actinomycin Derivatives: Structural Diversification and Biological Activities

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Actinomycins are chromopeptide antibiotics exhibiting remarkable structural diversity and broad bioactivity. This review traces their development from naturally occurring D‐, X‐, A‐, G‐, Y‐, and Z‐type analogs to precursor‐directed, synthetic, and semisynthetic derivatives.

Rapid screening of staphylokinase protein variants using an unpurified cell‐free expression system

open access: yesFEBS Open Bio, Volume 16, Issue 8, Page 1452-1458, August 2026.
An unpurified cell‐free protein synthesis (CFPS) platform enables rapid functional screening of staphylokinase variants. Direct plasminogen‐activation assays performed in microplate format provide real‐time activity readouts, allowing rapid identification and ranking of variants with improved or reduced fibrinolytic activity without protein ...

The RNA‐Binding Protein PARN Remodeled 3′ UTR Structure Defines Poly(A)‐Loading Sites to Mediate Immunoglobulin Homeostasis

open access: yesAdvanced Science, Volume 13, Issue 43, 3 August 2026.
ABSTRACT Class Switch Recombination (CSR) is essential for generating high‐affinity antibody isotypes from IgM during adaptive humoral responses. Despite well‐established roles for various transcription factors, whether CSR is subject to dedicated post‐transcriptional control represents a significant gap in knowledge.

NAT10‐Mediated ac4C Modification of circANKRD12 Reprograms the Tumor Microenvironment

open access: yesAdvanced Science, Volume 13, Issue 46, 17 August 2026.
NAT10‐dependent acetylation of circANKRD12 drives translation of the circANKRD12_354aa protein, which binds HDAC2 to stabilize c‐Myc via deubiquitination, promoting multiple myeloma (MM) cell proliferation. Concurrently, the circANKRD12‐HDAC2 axis suppresses H3ac‐mediated transcription of IFN‐γ, TNF‐α, and GZMB in NK cells, leading to NK cell ...

Proteomic Differentiation of Colorectal Cancer From Normal Tissue via Ex Vivo E‐Biopsy: A Novel Approach to Molecular Sampling for Diagnostic Precision

open access: yesCancer Medicine, Volume 15, Issue 8, August 2026.
ABSTRACT Colorectal cancer (CRC) is one of the most common malignancies worldwide. Early and accurate diagnosis remains a clinical priority, yet current biopsy techniques are invasive, spatially limited, and may not capture the molecular heterogeneity of tumors.

Morphological Characterization and Complete Mitochondrial Genome of a New Epizoic Hexamerous Brittle Star Gymnolophus sexradia sp. Nov

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
This study describes a new hexamerous epizoic brittle star species, Gymnolophus sexradia sp. nov., from the South China Sea, which lives on crinoid hosts and exhibits a six‐armed body plan possibly indicating fissiparity. Its vertebral and arm plate structures enhance horizontal flexibility for grasping the host, and phylogenetic analysis based on ...

De Novo Assembly and Comparative Mitochondrial Genome Analysis of Three Salt Marsh Specialist Ground Beetle Species (Coleoptera: Carabidae)

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We assembled and analyzed the complete mitochondrial genomes of 10 individuals from the salt marsh ground beetles Bembidion minimum, Dicheirotrichus gustavii, and Pogonus chalceus, revealing the conserved insect gene order, the typical set of 37 mitochondrial genes, and a pronounced AT‐bias (~80%).

Mitochondrial Genome Sequencing and Phylogenetic Analysis of Myotis pequinius and M. chinensis

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
This study first determined the complete mitochondrial genomes of Myotis pequinius (17,395 bp) and M. chinensis (17,014 bp), which both contain 13 protein‐coding genes, 22 tRNAs, 2 rRNAs, and a D‐loop, exhibiting an AT‐rich base composition. Phylogenetic analysis based on the 13 protein‐coding genes revealed that the two species are closely related and

Beyond a Metabolite: Lactylation as a Pivotal Regulator of Colorectal Cancer Pathogenesis and Treatment Resistance

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
This review elucidates how lactylation, a novel histone modification driven by lactate, regulates colorectal cancer pathogenesis. We summarize its roles in tumor progression, metastasis, stemness, immunosuppression, and therapy resistance, and discusses the promising therapeutic strategies of targeting the lactylation pathway.
