Nanosize Non-Viral Gene Therapy Reverses Senescence Reprograming Driven by PBRM1 Deficiency to Suppress iCCA Progression.

Polybromo-1 (PBRM1) serves as a crucial regulator of gene transcription in various tumors, including intrahepatic cholangiocarcinoma (iCCA). However, the exact role of PBRM1 in iCCA and the mechanism by which it regulates downstream target genes remain unclear. This research has revealed that PBRM1 is significantly downregulated in iCCA tissues, and this reduced expression is linked to aggressive clinicopathological features and a poor prognosis.

Experiences and opinions of adults with type 1 diabetes on the android-based open-source closed-loop system in China: a qualitative study.

Objective: As an emerging technology, Android-based open-source closed-loop system also called Android Artificial Pancreas System (AAPS), has been increasingly validated by evidence for its effectiveness in improving glycaemic outcomes, positioning it as a crucial option for managing type 1 diabetes (T1D).

A self-gelling hemostatic powder boosting radiotherapy-elicited NK cell immunity to combat postoperative hepatocellular carcinoma relapse.

Liver resection represents a main curative treatment for patients with early-stage hepatocellular carcinoma (HCC), but there is a rather high incidence of postoperative HCC relapse, which severely shortens long-term survival time. Currently, no standard adjuvant strategies are available for preventing HCC relapse in clinical practice. Impaired natural killer (NK) cell anti-tumor immunity has been disclosed as a crucial root of HCC relapse, indicating that reinstating NK cell anti-tumor immunity may show promise to curb HCC relapse.

Proximity Labeling and Genetic Screening Reveal that DSG2 is a Counter Receptor of Siglec-9 and Suppresses Macrophage Phagocytosis.

Biomimetic nanostructural materials based on placental amniotic membrane-derived nanofibers for self-healing and anti-adhesion during cesarean section.

Cesarean section (CS) is highly prevalent surgery among females. However, current absorbable anti-adhesion membranes used clinically can partially prevent postoperative adhesions but show limited efficacy in tissue regeneration, leaving post-cesarean women at risk for severe complications including cesarean scar pregnancy, placenta previa, and uterine rupture. Herein, we designed a fully amniotic membrane (AM)-derived biomimetic nanostructural materials (AM-BNMs) as an anti-adhesion barrier, and validated its therapeutic efficacy in a rat CS model.
