Mechanism elucidation of cell‐selective fluorescent probes

Smart Molecules, EarlyView.
This perspective outlines five mechanistic strategies—Protein‐oriented, carbohydrate‐oriented, lipid‐oriented, gating‐oriented, and metabolism‐oriented live‐cell distinctions—for achieving cell‐selective fluorescence in live‐cell imaging. By classifying probes based on their interactions with proteins, carbohydrates, lipids, transporters, or metabolic ...

Fluorophore Modulates Intracellular Distribution of Enzyme‐Instructed Self‐Assembly of Short Peptides in Osteosarcoma Cells

Small Methods, EarlyView.
Fluorophores at the peptide C‐terminus reprogram EISA behavior in osteosarcoma cellsshifting ER vs mitochondrial targeting, altering assembly, and tuning cytotoxicity. Abstract Enzyme‐instructed self‐assembly (EISA) of peptides offers a versatile strategy for developing intracellular nanomedicines, yet the role of C‐terminus fluorophores in modulating ...

Targeting hexokinase 2 to induce breast cancer cell senescence

British Journal of Pharmacology, EarlyView.
Background and Purpose Hexokinase 2 (HK2) is a key enzyme linked to high tumour cell proliferation. Its inhibitors such as 3‐bromopyruvic acid (3‐BP) induce cancer cell death, highlighting HK2 modulation as potential anti‐cancer treatment. However, standard chemotherapies often cause the emergence of senescent cancer cells, which goes along with cell ...

IAP Antagonists Selectively Eliminate Therapy‐Induced Senescent Cancer Cells via TNFα‐Independent Apoptosis

Cancer Science, EarlyView.
Upon chemotherapy, a subset of cancer cells enters a senescent state, referred to as TIS. When IAP antagonists are administered, TIS cells are selectively eliminated through TNFα‐independent apoptosis. TNFα secreted by TIS cancer cells may also act in a paracrine manner to enhance extrinsic apoptosis in neighboring non‐senescent cancer cells.

Ageing‐Dependent Thyroid Hormone Receptor α Reduction Activates IP3R1‐Meditated Ca2+ Transfer in MAM and Exacerbates Skeletal Muscle Atrophy in Mice

Cell Proliferation, EarlyView.
During skeletal muscle ageing, down‐regulation of TRα expression activates IP3R1 transcriptional expression, promotes MAM calcium transport, triggers mitochondrial calcium overload and apoptosis, leading to skeletal muscle atrophy. Restoring TRα expression can improve IP3R1‐mediated mitochondrial calcium overload and apoptosis in ageing skeletal muscle

Beyond nocardioform: Transcriptionally active microbes and host responses in equine mucoid placentitis

Equine Veterinary Journal, EarlyView.
Abstract Background Nocardioform placentitis (NP) is an understudied form of equine placentitis historically attributed to nocardioform bacteria, yet it remains uncertain whether these organisms are the sole pathogens involved. Objectives To elucidate the pathophysiology of NP and the host–pathogen interaction. Study Design In vivo clinical multi‐omics

Structural analysis of the NifL‐NifA complex reveals the molecular basis of anti‐activation of nitrogen fixation gene expression in Azotobacter vinelandii

The FEBS Journal, EarlyView.
Using cryo‐EM combined with biochemical and genetic approaches, we mapped the interaction surface between NifL and NifA to gain insights into the regulation of nitrogen fixation genes in A. vinelandii. Our findings suggest that NifL, a homolog of histidine kinases lacking phosphorylation activity, evolved to act as a steric block of NifA activity ...
