Mitochondrial Calcium Uniporter Drives Chemoresistance in Pancreatic Cancer via Glutathione‐Mediated Stemness Maintenance

open access: yesAdvanced Science, EarlyView.
PDAC has a poor prognosis due to chemoresistance. We revealed that MCU upregulation is associated with chemoresistance and stemness in PDAC. MCU‐mediated Ca2+ influx induced ER stress, activating the PERK‐ATF4/NRF2 axis to enhance PSAT1/SLC711 expression and glutathione synthesis, reducing ROS and maintaining stemness.

De Novo Gene Transcription of Connexin Mediates Cytoplasmic Fluid Exchange and Flocking Transitions in Physiological and Cancerous Epithelial Systems

open access: yesAdvanced Science, EarlyView.
EGF‐induced de novo transcription of connexins Cx26 and Cx31 promotes flocking behavior that fluidizes epithelia and enables coordinated collective migration. Connexin‐driven cytoplasmic exchange mechanistically links growth‐factor signaling to invasive dynamics.

Unexpected Metastasis of High Grade Serous Ovarian Cancer to Breast: Case Report and Literature Review [PDF]

open access: yes, 2016
Introduction: Metastasis of ovarian serous carcinoma to breast and/or axillary lymph nodes represents an unusual event. Nevertheless, their detection and distinction from mammary carcinoma are of huge clinical importance because the treatment and ...

Positive Feedback Loop of Histone Lactylation‐Driven HNRNPC Promotes Autophagy to Confer Pancreatic Ductal Adenocarcinoma Gemcitabine Resistance

open access: yesAdvanced Science, EarlyView.
Histone 3 lysine18 lactylation (H3K18la) drives heterogeneous nuclear ribonucleoprotein C (HNRNPC) overexpression, activating autophagy to mediate gemcitabine resistance by stabilizing TNF receptor‐associated factor 6 (TRAF6) mRNA. Concurrently, HNRNPC stabilizes aldehyde dehydrogenase 1 family member A3 (ALDH1A3) mRNA, which enhances glycolysis and ...

Magnetic resonance imaging findings of high-grade ductal carcinoma in situ of the male breast: A case report

open access: yesSAGE Open Medical Case Reports, 2018
Ductal carcinoma in situ in men is incredibly rare and detection by conventional mammography and ultrasound is often challenging. We report an unusual case of a 50-year-old male, with no family history of breast cancer, who presented with an 8-year ...

CD168 Identifies Proliferating Pancreatic Islet Cells in Murine and Human

open access: yesAdvanced Science, EarlyView.
This study identifies CD168 as a conserved surface marker for proliferating β‐cells in mouse, human islets, and pancreatic islet tumors. CD168⁺ cells show high proliferation and low insulin expression. CD168+ cells form mostly uni‐β lineage clones, and some of the clones are multi‐lineage.
