Heterogeneity Landscape of Circulating Tumor Cells in Clinical Utility

open access: yesAdvanced Therapeutics, EarlyView.
This study reports the heterogeneity spectrum of circulating tumor cells. The factors involved in the spectrum promote CTCs to overcome barriers in the metastatic cascade but impact the clinical outcome of cancer patients. In summary, the heterogeneities in association with CTCs ultimately reduce patient survival and facilitate increasing mortality of ...

Fibronectin Fibers Progressively Lose Their Tension in Invasive Human Breast Carcinoma while Being Tensed in DCIS and Healthy Breast Tissue

open access: yesAdvanced Science, EarlyView.
Extracellular matrix remodeling is crucial in cancer progression. Using a peptide to probe the tension of ECM fibers, it was found that Fibronectin fibers gradually lose tension as human breast carcinoma progresses, while their tension is maintained in ductal carcinoma in situ (DCIS), the non‐invasive precursor of breast cancer. This loss of tension is

NOX2 Contributes to High‐Frequency Outer Hair Cell Vulnerability in the Cochlea

open access: yesAdvanced Science, EarlyView.
This study first identifies NOX2 as a differentially expressed gene related to oxidative damage in the apical and basal turns through single‐cell RNA sequencing. NOX2 gene knockout mitigates OHCs damage caused by neomycin and noise and enhances Nrf2 expression and nuclear translocation.

Unraveling the Role of MDK‐SDC4 Interaction in Pancreatic Cancer‐Associated New‐Onset Diabetes by Single‐Cell Transcriptomic Analysis

open access: yesAdvanced Science, EarlyView.
Midkine (MDK) is a mediator of the interaction between pancreatic cancer and beta cells. MDK, which originated from pancreatic ductal adenocarcinoma cells, exerted deleterious effects on paraneoplastic beta cells by binding to the SDC4 receptor on the beta cell surface and subsequently downregulating the Ras signaling pathway, thereby impairing insulin
