查询词典 caliciform cells

Ransforming growth factor beta TGF-β is a potent growth suppressor of normal epithelial cells. However, many types of invasive cancer cells (e.g. breast cancer frequently overproduce TGF-β to enhance their growth and metastasis. Quite frequently, these cells do not possess a functional type II TGF-β receptor, indicating an aberrant TGF-β signaling is responsible for promoting cell growth.

Transforming growth factor beta 对於正常的上皮细胞是一个很强的生长抑制因子，然而，许多种具有蔓延侵犯性的癌细胞常常是表现大量的 TGF-β来促进细胞生长与转移，这些癌细胞通常不表现具有功能性的第二型 TGF-β receptor，显示有另类的 TGF-β讯息传递可以促进细胞生长。

Methods After fixed by paraformaldehyde, vascular endothelial cells from pigs were co-cultured in vitro with natural killer cells from Chinese monkeys at different ratios.

Methods: Human leukemia cell line K562 was treated with different concentrations of WM. The proliferation of K562 cells was examined by MTT assay. DNA damage in K562 cells was examined by single cell gel electrophoresis assay, and apoptosis of K562 cells was detected by Annexin V-FITC/PI double staining. The expressions of total Akt, phosphorate Akt, and NF-κB p65 mRNA and protein were detected by RT-PCR and Western blotting, respectively.
