XPO1 is upregulated in many malignant tumors and is associated with poor prognosis.

Overexpression of ELF3 in the PTEN-deficient lung epithelium promotes lung cancer development by inhibiting ferroptosis.

Ferroptosis has been shown to play a crucial role in preventing cancer development, but the underlying mechanisms of dysregulated genes and genetic alternations driving cancer development by regulating ferroptosis remain unclear. Here, we showed that the synergistic role of ELF3 overexpression and PTEN deficiency in driving lung cancer development was highly dependent on the regulation of ferroptosis. Human ELF3 (hELF3) overexpression in murine lung epithelial cells only caused hyperplasia with increased proliferation and ferroptosis.

Effects of FGFR2b-ligand signaling on pancreatic branching morphogenesis and postnatal islet function.

Pancreatic development is a complex process vital for maintaining metabolic balance, requiring intricate interactions among different cell types and signaling pathways. Fibroblast growth factor receptors 2b (FGFR2b)-ligands signaling from adjacent mesenchymal cells is crucial in initiating pancreatic development and differentiating exocrine and endocrine cells through a paracrine mechanism. However, the precise critical time window that affects pancreatic development remains unclear.

There is a lack of evidence regarding the effectiveness and safety of traditional Chinese medicine in preventing ARE.

Coupling Probiotics with CaO Nanoparticle-Loaded CoFeCe-LDH Nanosheets to Remodel the Tumor Microenvironment for Precise Chemodynamic Therapy.

Chemodynamic therapy (CDT) has become an emerging cancer treatment strategy with advantages of tumor-specificity, high selectivity, and low systemic toxicity. However, it usually suffers from low therapeutic efficacy. This is caused by low hydroxyl radical (·OH) yield arising because of the relatively high pH, overexpressed glutathione, and low HO concentration in the tumor microenvironment (TME).

This study aimed to assess the catalytic efficiency of 22 CYP3A4 allelic variants on the in vitro oxidative metabolism of methadone. We utilized a baculovirus-insect cell expression system to produce recombinant CYP3A4 variants and subsequently assessed their catalytic activity in the N-demethylation of methadone.

A green, versatile, and facile strategy for anti-biofouling surface with ultra-high graft density polyethylene glycol.

Implantable catheters are susceptible to severe complications due to non-specific protein adhesion on their surfaces. Polyethylene glycol (PEG) coatings, the gold standard for resistance to non-specific protein adhesion, present a challenge in achieving high-density grafting, which significantly restricts their use as anti-biofouling coatings. Herein, we exploited the strong interaction between polyphenols (PCs) and polycations (K6-PEG) to graft PEG onto the surface of PC-Cu (A network of metal polyphenols composed of proanthocyanidins and metal copper ions, with expectation for the coating with excellent resistance to non-specific protein adhesion (PC-Cu@K6-PEG).
