Progress on the Signal Transduction and Crosstalk Mechanism of Humic Substances in Promoting Plant Root and Shoot Growth

Guangdong nongye kexue
Humic substances (HS), a natural polymer isomeric mixture, is an important component of terrestrial ecosystem. Its promotion effect on plant growth has been widely studied in recent years. Multiple signaling pathways play an important role in the process

Mitochondrial SLC25A46 Rewires Fatty Acid Oxidation to Promote Cell Proliferation and Ferroptosis Evasion in Ovarian Cancer by Stabilizing CACT

Advanced Science, EarlyView.
Mitochondrial SLC25A46 is upregulated in ovarian cancer (OC) and correlates with poor prognosis. SLC25A46 stabilizes CACT to activate fatty acid oxidation, increasing ATP and NADPH production to drive cell proliferation and ferroptosis evasion. SLC25A46 silencing sensitizes OC cells to ferroptosis and carboplatin, offering a promising therapeutic ...

A Universal Protein Ladder for Standardization of Diverse FRET Assays

Advanced Science, EarlyView.
Translating FRET measurements from in vitro to intracellular environments requires universal benchmarks. We present a modular protein ladder using TPR motifs to harmonize data across diverse platforms. This predictable calibration curve bridges single molecule FRET measurements, with cell based measurements including FLIM‐FRET.

The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

Advanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

UFL1‐Mediated UFMylation of ENO1 Restrains Aerobic Glycolysis and Colorectal Cancer Progression

Advanced Science, EarlyView.
UFMylation restrains aerobic glycolysis and colorectal cancer progression by modifying the glycolytic enzyme ENO1. Pharmacological enhancement of the UFL1–ENO1 interaction by the FDA‐approved antibiotic torezolid promotes ENO1 UFMylation, suppresses tumor metabolism, and sensitizes colorectal cancer to chemotherapy, revealing an actionable metabolic ...
