Neutrophil Extracellular Traps Amplify Neutrophil Recruitment and Inflammation in Neutrophilic Asthma by Stimulating the Airway Epithelial Cells to Activate the TLR4/NF-κB Pathway and Secrete Chemokines

Formation of neutrophil extracellular traps (NETs) and neutrophil swarming was seen in a mouse model of neutrophilic asthma. Additionally, NETs were found to stimulate airway cells to express CXCL1, CXCL2, and CXCL8 via the TLR4/NF-κB pathway, which recruits neutrophils to the inflammation site.

Chelerythrine Suppresses Proliferation and Metastasis of Human Prostate Cancer Cells via Modulating MMP/TIMP/NF-κB System

The addition of chelerythrine significantly inhibited the proliferation of androgen-independent prostate cancer DU145 and PC-3 cells at the concentration of 5 and 10 μM, but not on androgen-dependent prostate cancer LNCaP cells as well as normal prostate epithelial cell line PrEC cells.

ERK/MAPK Signaling Is Essential for Intestinal Development through Wnt Pathway Modulation

Scientists found that deletion of Erk1/2 in intestinal epithelial cells at embryonic stages resulted in an unexpected increase in cell proliferation and migration, expansion of intestinal stem cells and formation of polyp-like structures, leading to postnatal death.

Berberine Inhibits Intestinal Epithelial Barrier Dysfunction in Colon Caused by Peritoneal Dialysis Fluid by Improving Cell Migration

In the wound healing assay, berberine exhibited the ability to promote cell migration, indicating that berberine could probably recover the function of intestinal epithelial cells when the intestinal epithelial barrier was damaged by the peritoneal dialysis fluid.

AUF1 Promotes Stemness in Human Mammary Epithelial Cells through Stabilization of the EMT Transcription Factors TWIST1 and SNAIL1

Scientists showed that AU-rich element RNA-binding protein 1 was an important inducer of the epithelial-to-mesenchymal transition process through stabilization of SNAIL1 and TWIST1 and the consequent promotion of breast cancer stem cells.

Distinct Phenotypes of Cancer Cells on Tissue Matrix Gel

Scientists investigated mammary epithelial cell phenotypes and metabolic profiles on animal breast extracellular matrix-derived tissue matrix gel, Col I, and Matrigel. Atomic force microscopy, fluorescence microscopy, acini formation assay, differentiation experiments, spatial migration/invasion assays, proliferation assay, and nuclear magnetic resonance spectroscopy were used to examine biological phenotypes and metabolic changes.
