Cyclic Strain and Macrophage‐Mediated Transport Govern Micron‐Sized PM2.5 Translocation across the Air–Blood Barrier

open access: yesAdvanced Science, EarlyView.
Using a dynamic, tri‐culture air‐blood barrier model, this study reveals that macrophage‐mediated transport governs micron‐sized particle translocation under cyclic strain. The process is highly size‐dependent that 2 µm particles are transported by macrophages, 0.2 µm particles diffuse passively, and 5 µm particles are effectively blocked.

Adapting the Interrelated Two-way Clustering method for Quantitative Structure-Activity Relationship (QSAR) Modeling of a Diverse Set of Chemical Compounds

open access: yes, 2013
Interrelated Two-way Clustering (ITC) is an unsupervised clustering method developed to divide samples into two groups in gene expression data obtained through microarrays, selecting important genes simultaneously in the process.

Folic Acid‐Modified Ginger‐Derived Exosome‐Like Nanoparticles Co‐Delivering Sunitinib Suppress Renal Cell Carcinoma via PI3K‐Akt Pathway Inhibition, P‐gp Downregulation, and Macrophage Reprogramming

open access: yesAdvanced Science, EarlyView.
FPD‐GELNs co‐deliver Su and bioactive components. This active‐passive dual‐targeting strategy suppresses the progression of RCC through the following mechanisms: 1) inhibition of the PI3K‐Akt signaling pathway; 2) downregulation of ABCB1/P‐gp to enhance the chemosensitivity of RCC to Su; and 3) reprogramming of macrophages toward M1 polarization and ...

TRIM38 Suppresses Breast Cancer Progression via Modulating SQSTM1 Ubiquitination and Autophagic Flux

open access: yesAdvanced Science, EarlyView.
TRIM38, an E3 ubiquitin ligase, suppresses breast cancer progression by inhibiting proliferation, migration, and invasion. Downregulated in breast tumor, its loss correlates with poor prognosis. Mechanistically, TRIM38 mediates K63‐linked ubiquitination of SQSTM1/p62 at K420, disrupting SQSTM1‐LC3 interaction and blocking autophagic flux.

The process of cancer. Part I. The role of selected factors in the induction of carcinogenesis

open access: yesJournal of Education, Health and Sport, 2019
Summary Introduction and objective: Cancer arises from genetic and epigenetic changes in the cell. Indication of the direct causes of cancer is no doubt very difficult, because the process of carcinogenesis is a multi-level and multi-stage. Knowledge of

Disrupting the Formation of YAP Condensates Promotes the Activation of AMPKα to Inhibit the Progression of Primary Liver Cancer

open access: yesAdvanced Science, EarlyView.
This study systematically investigates the function and molecular mechanisms of YAP phase separation in multiple primary liver cancers. These findings provide novel insights into phase separation‐mediated primary liver cancer development and validate targeted disruption of this process as an effective therapeutic strategy for primary liver cancer ...
