Compound C inhibits nonsense-mediated RNA decay independently of AMPK [PDF]

, 2018
The nonsense mediated RNA decay (NMD) pathway safeguards the integrity of the transcriptome by targeting mRNAs with premature translation termination codons (PTCs) for degradation.

Autophagy Inhibition by Fangji Huangqi Decoction Enhances Tumor Immunogenicity and Potentiates PD‐1 Blockade

Cancer Science, EarlyView.
In tumor cells, MHC‐I is typically degraded through autophagy, leading to reduced antigen presentation. However, Fangji Huangqi Decoction (FJHQ), acting as an autophagy inhibitor, suppresses lysosomal acidification, which in turn inhibits the degradation of MHC‐I. This results in increased surface expression of MHC‐I on tumor cells.

PTPN22 regulates NLRP3-mediated IL1B secretion in an autophagy-dependent manner [PDF]

, 2017
A variant within the gene locus encoding PTPN22 (protein tyrosine phosphatase, non-receptor type 22) emerged as an important risk factor for auto-inflammatory disorders, including rheumatoid arthritis, systemic lupus erythematosus and type 1 diabetes ...

A Curcumin‐Derived HSP70 Inhibitor Disrupts Lysosomal Function to Suppress Triple‐Negative Breast Cancer Progression

Cell Proliferation, EarlyView.
Novel curcumin‐derived M4 binds HSP70's ATPase domain, disrupting HSP70‐mediated lysosomes‐autophagy pathway to inhibit TNBC growth and metastasis, and synergizes with paclitaxel for potent combination therapy. ABSTRACT Structural modification of curcumin yielded a novel series of 1,4‐pentadien‐3‐one oxime ether derivatives, among which compound M4 ...

GCN2 in proteostasis: structural logic, signalling networks and disease

The FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.

Exercise‐related microRNAs in Caenorhabditis elegans regulate calcium homeostasis and mitochondrial dynamics: Conserved pathways, divergent microRNAs

The FEBS Journal, EarlyView.
Exercise‐related microRNAs cel‐miR‐249‐3p and cel‐miR‐77‐5p in C. elegans regulate lifespan, fitness, mitochondrial morphology and membrane potential. Although lacking direct mammalian orthologs, H2O2‐induced microRNAs mmu‐miR‐181a‐5p and mmu‐miR‐378a‐3p regulate myogenesis, autophagy, mitochondrial content and respiration in murine myoblasts ...

Disruption of iron metabolism resulting from Dmt1/Slc11a2 deficiency compromises Notch protein degradation and transcriptional activation

The FEBS Journal, EarlyView.
Divalent metal transporter 1 (Dmt1) maintains iron homeostasis and lysosomal proteostasis required for physiological Notch receptor–ligand signaling. Dmt1 loss lowers iron storage capacity (ferritin), increasing intracellular Fe2+, driving ROS and lipid peroxidation, and leading to lysosomal/mitochondrial dysfunction.

A Lavandula angustifolia flower extract and dipeptide‐4 blend modulates oxidative, glycative, autophagic and circadian pathways in human skin models

International Journal of Cosmetic Science, EarlyView.
The blend enhanced antioxidation, anti‐glycation, autophagy and circadian regulation in cell and skin models. Key markers included mitochondrial ROS, γ‐H2AX, AGEs, ATP, melatonin, LC3 and SOD. Significant improvements were visualized via fluorescence and quantified with statistical markers.
