A Soft Matrix Microenvironment Promotes Laterally Spreading Tumors via Oxidative Phosphorylation‐Dependent Cell Adhesion

open access: yesAdvanced Science, EarlyView.
Laterally spreading tumors (LSTs) are precancerous colorectal lesions characterized by a flat morphology. This study reveals a mechanochemical pathway through which a soft matrix microenvironment diminishes spatial constraints in intestinal adenomas. This process promotes deficiencies in tight junction proteins, mediated by the mechanoreceptor ADORA2B ...

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.

Smartly Assembled near‐Micron RF‐Responsive Agents Bridge Transarterial Embolization and Immunothermal Potentiation

open access: yesAdvanced Science, EarlyView.
ABSTRACT Hepatocellular carcinoma (HCC) remains a significant clinical challenge due to the limited efficacy of conventional treatments like surgery, radiofrequency ablation (RFA), and transarterial embolization (TAE). Here, we develop an innovative TAE and immunothermal therapy strategy based on smartly assembled near‐micron layered double hydroxide ...

Immunohistochemical Expression of Ki-67 and p53 and Their Prognostic Role in Ameloblastoma: A Longitudinal Study

open access: yesOman Medical Journal
Objectives: Ameloblastoma, comprising approximately 11% of all odontogenic tumors, is a locally aggressive tumor with a high recurrence rate. This study aimed to assess the immunohistochemical expression of Ki-67 and p53 and their association with ...

Inhibition of Focal Adhesion Restricts Chemoresistance in Pancreatic Cancer by Targeting SLC7A11 Mediated Ferroptosis

open access: yesAdvanced Science, EarlyView.
FAK signaling drives chemoresistance and tumor evolution in pancreatic ductal adenocarcinoma. The FAK inhibitor IN10018 restores gemcitabine sensitivity by inducing SLC7A11‐mediated ferroptosis through the PI3K‐Akt pathway and remodeling the tumor microenvironment, reducing mesenchymal components while enhancing CD8+ T‐cell infiltration in preclinical ...

A statistical mechanics approach to autopoietic immune networks

open access: yes, 2010
The aim of this work is to try to bridge over theoretical immunology and disordered statistical mechanics. Our long term hope is to contribute to the development of a quantitative theoretical immunology from which practical applications may stem.

Selenium‐Based Nanoplatforms: An Emerging Theranostic Paradigm for Gynecological Cancers

open access: yesAdvanced Science, EarlyView.
This reivew summarizes Selenium as a multifunctional anticancer regulator in gynecological cancers. It reduces tumor risk, enhances therapeutic efficacy, and reduces treatment toxicity. Selenium also overcomes chemoraditherapy resistance, improving overall treatment outcomes. ABSTRACT Gynecological cancers present significant therapeutic challenges due

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 ...

Photodynamic Priming and Minocycline Overcome Chemoresistance by Reprogramming the Pancreatic Tumor Immune Microenvironment In Vivo

open access: yesAdvanced Science, EarlyView.
Dual priming with minocycline and photodynamic priming reprograms the pancreatic tumor microenvironment to overcome chemoresistance. By suppressing DNA repair enzyme Tdp1, inducing photooxidative damage, and enhancing irinotecan delivery via light‐activated nanoencapsulation, this strategy remodels the tumor microenvironment and drives immune ...

KI-67 IMMUNOHISTOHEMICAL EXPRESSION IN PROSTATIC LESIONS

open access: yesThe Iraqi Journal of Medical Sciences, 2017
Background: The cell proliferation marker, ki-67, is a nuclear and nucleolar protein, which can be detected during all active phases of the cell cycle (G1, S, G2, and mitosis), but absent from cell resting phases.
