Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Dissecting pre- to post-implantation transition of DNA methylome-transcriptome dynamics in early mammalian development

Cell Reports
Summary: Pre- to post-implantation transition is an essential step for early mammalian development. The epigenome dynamics such as DNA methylome and transcriptome of embryos have been analyzed, while the coordination between these two molecular layers ...

Syndecan-4 negatively regulates antiviral signalling by mediating RIG-I deubiquitination via CYLD

Nature Communications, 2016
Syndecans are transmembrane proteoglycans implicated in diverse cellular activities. Here the authors show that Syndecan-4 via its cytosolic domain negatively regulates antiviral immunity by enhancing RIG-I interaction with a deubiquitinating enzyme CYLD,

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

Molecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Therapy-induced senescence in breast cancer: an overview

Exploration of Targeted Anti-tumor Therapy
Outcomes for women with breast cancer have improved dramatically in recent decades. However, many patients present with intrinsic drug resistance and others are initially sensitive to anti-cancer drugs but acquire resistance during the course of their ...

Computation of a Theoretical Membrane Phase Diagram, and the Role of Phase in Lipid Raft-Mediated Protein Organization

, 2018
Lipid phase heterogeneity in the plasma membrane is thought to be crucial for many aspects of cell signaling, but the physical basis of participating membrane domains such as "lipid rafts" remains controversial.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Multilayered regulation of GluK3 kainate receptors is mediated by Neto subunits and zinc

Communications Biology
Kainate receptors (KARs), a distinct subfamily of ionotropic glutamate receptors, are critical modulators of synaptic transmission and network excitability. Their function is intricately regulated by auxiliary subunits and endogenous ions.
