Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants
Advanced Science, EarlyView.The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.

Oncogenic Gain of Function in Glioblastoma Is Linked to Mutant p53 Amyloid Oligomers. [PDF]
, 2020 Tumor-associated p53 mutations endow cells with malignant phenotypes, including chemoresistance. Amyloid-like oligomers of mutant p53 transform this tumor suppressor into an oncogene.

CspA, the Major Cold-shock Protein of Escherichia coli, Is an RNA Chaperone*
Journal of Biological Chemistry, 1997 CspA, the major cold-shock protein of Escherichia coli, is dramatically induced during the cold-shock response. The amino acid sequence of CspA shows 43% identity to the “cold-shock domain” of the eukaryotic Y-box protein family, which interacts with RNA

Advanced Science, EarlyView.NET‐DNA is enriched during early endometriotic lesion establishment and drives anoikis resistance by promoting an ANXA2–TMEM215–BiP axis. This pathway strengthens ER–mitochondria contacts, enhances PINK1/Parkin‐associated mitophagy, preserves mitochondrial homeostasis, and supports ectopic stromal cell survival, thereby facilitating lesion persistence ...

RNA compaction and iterative scanning for small RNA targets by the Hfq chaperone
Nature CommunicationsRNA-guided enzymes must quickly search a vast sequence space for their targets. This search is aided by chaperones such as Hfq, a protein that mediates regulation by bacterial small RNAs (sRNAs).

PLoS ONE, 2014 Hfq is a bacterial RNA chaperone involved in the riboregulation of diverse genes via small noncoding RNAs. Here, we show that Hfq is critical for the uropathogenic Proteus mirabilis to effectively colonize the bladder and kidneys in a murine urinary ...

Advanced Science, EarlyView.This study reveals the dual role of celecoxib in intervertebral disc degeneration. While low concentrations are protective, high concentrations induce toxicity by upregulating HSP90, which synergizes with USP15 to deubiquitinate and stabilize RBX1. This leads to degradation of COMMD1/ATP7B, copper dyshomeostasis, and ultimately, cuproptosis.

Metabolism‐Based Biomarkers for Rapid Phenotypic Antibiotic Susceptibility Testing
Advanced Science, EarlyView.Metabolic differences emerging after antibiotic exposure provide rapid phenotypic signals of susceptibility and resistance. This review summarizes metabolic biomarkers for rapid phenotypic AST, associated with nutrient uptake, respiratory activity, metabolic reprogramming, and enzymatic function. ABSTRACT The accelerating global crisis of antimicrobial
