Stromal‐Derived IL‐8 Promotes M2 Macrophage Polarization via the RhoA/MRTF‐A/SRF Transcriptional Axis to Impair CD8+ T Cell Cytotoxicity in Lung Cancer

open access: yesAdvanced Science, EarlyView.
In the recondite pulmonary neoplastic milieu, DESMIN+ cancer‐associated fibroblasts function as the paramount stromal source of IL‐8, precipitating a deleterious immunological metamorphosis by engaging CXCR2 receptors on the myeloid lineage. This paracrine stimulus triggers a mechanotransduction cascade characterized by RhoA‐dependent actin ...

Perivascular Matrix Densification Dysregulates Angiogenesis and Activates Pro‐Inflammatory Endothelial Cells

open access: yesAdvanced Science, EarlyView.
Perivascular matrix densification promotes the emergence of aberrant endothelial tip cells (ATECs) that invade and persist within fibrotic microenvironments. Using in vivo lineage tracing and a human microvessel model, this study shows that fibrous matrix cues destabilize VE‐cadherin–mediated junctions to gate TGF‐β signaling, inducing a pro ...

Mitigating Cancer Therapy–Related Cognitive Impairment by Targeted Activation of Undruggable Phosphatase

open access: yesAdvanced Science, EarlyView.
An RVG‑engineered exosomal saRNA delivery system (RVG‑EVs‑saPtpro) effectively targets and activates hippocampal PTPRO, functioning as a “molecular brake” to alleviate cancer therapy‑related cognitive impairment (CTRCI) by enhancing neuronal survival, neurogenesis, and synaptic plasticity.

TSPYL5 Promotes Triple‐Negative Breast Cancer Metastasis by Antagonizing USP10‐Mediated PTEN Stabilization to Unleash a ZEB1‐Dependent EMT Program

open access: yesAdvanced Science, EarlyView.
The hyperactivation of PI3K/AKT signaling in PTEN wild‐type triple‐negative breast cancer represents a clinical paradox. We delineate a novel post‐translational regulatory axis wherein the oncogene TSPYL5 competitively antagonizes the deubiquitinase USP10.

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Pulmonary Vein Variation: A Case report study [PDF]

open access: yesMajallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Īlām
Introduction:  The heart consists of four chambers: the right atrium, right ventricle, left atrium, and left ventricle. Pulmonary veins return oxygenated blood from the lungs to the left atrium, typically through four veins—two from each lung—entering ...

Morphological dilemma: Anomalous pulmonary venous confluence or cor triatriatum—does it matter?

open access: yesJournal of the Saudi Heart Association, 2018
Cardiac variant of total anomalous pulmonary venous return is a rare entity, whereby all the pulmonary veins drain directly to the right atrium or coronary sinus. The effective left heart blood flow channels through a small stretched patent foramen ovale
