Expression of \u3cem\u3eRhizobium leguminosarum\u3c/em\u3e CFN42 Genes for Lipopolysaccharide in Strains Derived from Different \u3cem\u3eR. leguminosarum\u3c/em\u3e Soil Isolates [PDF]

open access: yes, 1990
Two mutant derivatives of Rhizobium leguminosarum ANU843 defective in lipopolysaccharide (LPS) were isolated. The LPS of both mutants lacked O antigen and some sugar residues of the LPS core oligosaccharides.

QSOX2‐Mediated Disulfide Bond Modification Enhances Tumor Stemness and Chemoresistance by Activating TSC2/mTOR/c‐Myc Feedback Loop in Esophageal Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
High QSOX2 enhances stemness, drug resistance, and metastasis of ESCC cells. QSOX2‐mediated disulfide bond modification activates mTOR/c‐Myc signaling. CAFs‐secreted IGF‐1 drives mTOR/c‐Myc/QSOX2 positive feedback loop. Combining Ebselen, rapamycin, and cisplatin induces tumor dormancy in mice.

3D‐Printed Titanium Trabecular Scaffolds with Sustained Release of Hypoxia‐Induced Exosomes for Dual‐Mimetic Bone Regeneration

open access: yesAdvanced Science, EarlyView.
This study presents 3D‐printed Ti‐6Al‐4V trabecular scaffolds combined with hypoxia‐induced exosomes encapsulated in PEGDA/GelMA microspheres for sustained release. The scaffolds mimic the structure of natural bone, while the exosome delivery system enhances osteogenesis and angiogenesis, significantly promoting bone regeneration and offering a ...

Dissection of Nodule Development by Supplementation of \u3cem\u3eRhizobium leguminosarum\u3c/em\u3e biovar \u3cem\u3ephaseoli\u3c/em\u3e Purine Auxotrophs with 4-Aminoimidazole-5-Carboxamide Riboside [PDF]

open access: yes, 1992
Purine auxotrophs of Rhizobium leguminosarum biovar phaseoli CFN42 elicit uninfected pseudonodules on bean (Phaseolus vulgaris L.). Addition of 4-aminoimidazole-5-carboxamide (AICA) riboside to the root medium during incubation of the plant with these ...

The E3 Ubiquitin Ligase ARIH1 Facilitates Colorectal Cancer Progression by Promoting Oxidative Phosphorylation via the Mitochondrial Translocation of K63‐Linked Ubiquitinated PHB1

open access: yesAdvanced Science, EarlyView.
The RBR E3 ubiquitin ligase ARIH1, which is upregulated in colorectal cancer cells, promotes cell growth and metastasis and correlates with an unfavorable CRC prognosis. Mechanistically, ARIH1 catalyzes K63‐linked ubiquitination of PHB1, enhancing the interaction between PHB1 and Akt.

Inoculation of Acacia mangium with alginate beads containing selected Bradyrhizobium strains under field conditions : long-term effect on plant growth and persistence of the introduced strains in soil [PDF]

open access: yes, 1994
Les essais d'innoculation faits avec 4 souches différentes de Bradyrhizobium ont un effet positif sur la croissance de Acacia mangium dont la provenance est aussi hautement significative. A long terme la souche Aust 13c a toujours un effet positif.

Responsive ROS‐Augmented Prodrug Hybridization Nanoassemblies for Multidimensionally Synergitic Treatment of Hepatocellular Carcinoma in Cascade Assaults

open access: yesAdvanced Science, EarlyView.
This study proposes a novel HCC therapy using CA‐4S2@ES‐Cu nanomedicines to amplify cuproptosis, enhancing chemotherapy and immunotherapy. CA‐4 and ES‐Cu synergistically inhibit tumor growth, induce immune responses, and reverse the immunosuppressive microenvironment, offering an effective multidimensional therapeutic strategy for HCC treatment ...

Fn14 Controls the SIRT2‐Mediated Deacetylation of Slug to Inhibit the Metastasis of Epithelial Ovarian Cancer

open access: yesAdvanced Science, EarlyView.
It is reported that Fn14 inhibited EOC metastasis by regulating Slug‐mediated EMT. Furthermore, Fn14 altered the subcellular localization of SIRT2 by interacting with SIRT2, leading to reduced SIRT2 shuttling into the nucleus and subsequently promoting the acetylated degradation of Slug.
