Epigenetic Silencing of RFX7 Defines a Transcriptional Axis Linking Lactate Metabolism to Immune Checkpoint Therapy in Glioblastoma

open access: yesAdvanced Science, EarlyView.
Glioblastoma (GBM) exhibits RFX7 silencing via promoter hypermethylation, which downregulates PIK3IP1 to activate PI3K/AKT signaling, increase lactate accumulation, and enhance histone H4K12 lactylation. This lactylation upregulates PD‐L1/CSF1 expression and drives the immunosuppressive microenvironment formation.

Tumor‐Intrinsic ARHGEF3 Enhances Antitumor Immunity by Promoting T‐Cell Infiltration and Limiting Myeloid Cell‐Mediated Immunosuppression

open access: yesAdvanced Science, EarlyView.
ARHGEF3 is broadly downregulated across human cancers and correlates with patient prognosis. Tumor‐intrinsic ARHGEF3 activates the RHOA–ROCK–PTEN cascade to inhibit AKT signaling, thereby promoting chemokine‐driven T‐cell infiltration and relieving lipid‐mediated myeloid immunosuppression.

The role of PTEN in cardioprotection against ischaemia-reperfusion injury

open access: yes, 2009
Activation of the PI3K/AKT pathway protects the heart from ischaemia-reperfusion injury. Phosphatase and Tensin Homolog deleted on Chromosome10 (PTEN) is a negative regulator of this pathway.

Endogenous Engineering Reprograms Extracellular Vesicles for Enhanced Therapeutic Function

open access: yesAdvanced Science, EarlyView.
This review explains how Extracellular vesicles‐producing cells can be endogenously engineered to load therapeutic proteins and nucleic acids. We summarize physiological and genetic strategies that harness native sorting pathways for selective cargo loading.

AN INTRONIC VARIANT IN PTEN GENE IS PROBABLY INVOLVED IN SPLICING ALTERATION EVENTS.

open access: yes, 2019
PTEN is a gate-keeper tumor-suppressor gene involved in various cell cycle pathways. Germline mutations of one allele of PTEN were found associated with Cowden syndrome, which is an inherited disease characterized by multiple hamartomas.

ANXA2‐mediated Phagocytosis Generates AR+ Macrophages to Confer Enzalutamide Resistance in Prostate Cancer

open access: yesAdvanced Science, EarlyView.
A novel resistance mechanism is mediated through phagocytosis of cancer cells by AR+ TAMs. This process, dependent on ANXA2, enables macrophages to acquire AR protein from engulfed tumor cells. The internalized AR translocates into the macrophage nucleus, where it binds directly to the IL‐6 promoter, augmenting IL‐6 transcription and secretion ...

“Membrane‐Guided” Repair Strategy: Precision Delivery of GGT1 Degrader for Targeted Repair and Regeneration of Spinal Cord Neurons

open access: yesAdvanced Science, EarlyView.
This study confirms that GGT1 is a key driver of neuronal ferroptosis following spinal cord injury. We developed NSCm@EA, a biomimetic delivery system coated with neural stem cell membranes, for precise delivery of enocyanin to injured neurons. By combining targeted delivery with ubiquitination degradation mechanisms, this system promotes MGRN1 ...

PTEN recruitment controls synaptic and cognitive function in Alzheimer's models

open access: yes, 2016
Dyshomeostasis of amyloid-β peptide (Aβ) is responsible for synaptic malfunctions leading to cognitive deficits ranging from mild impairment to full-blown dementia in Alzheimer's disease.

Nucleic Acid Therapeutics for “Undruggable” Cancer Targets: Mechanisms, Challenges, and Prospects

open access: yesAdvanced Science, EarlyView.
Nucleic acid therapeutics bypass the structural limitations of conventional drugs by targeting mRNA rather than proteins. This review examines how antisense oligonucleotides, siRNAs, miRNAs, aptamers, and mRNA vaccines intervene against historically undruggable oncoproteins including Ras, MYC, and p53, highlighting mechanistic advances, delivery ...

Arresting times for PTEN [PDF]

open access: yesThe EMBO Journal, 2011
EMBO J 30 13, 2557–2568 (2011); published online June032011 [PMC free article] [PubMed] The tumour suppressor PTEN (phosphatase and tensin deleted on chromosome 10) is an important regulator of cell proliferation and migration. In this issue of The EMBO Journal, Lima-Fernandes and colleagues show that the universal signalling scaffold protein, β ...
