后分别测宫颈癌细胞和宫颈癌细胞外泌体中
CXCL1
表达量,均减少(
P
<0. 05);低表达
CXCL1
后可明显抑制宫颈癌增殖、侵袭和迁移能力。

Objective
2
To explore the effects of exosomal
CXCL
on the biological behavior of cervical cancer cells and its underlying mechanisms.
Methods
2
Chemokine
CXCL
was first screened through bioinformatics databases. The GEPIA database was analyze
CXCL
expression in cervical cancer tissues and adjacent normal cervical tissues. Western blot was performed to detect
CXCL
expression levels in cervical cancer cells (Caski) and normal cervical epithelial cells (H8). The successful isolation of exosomes was confirmed by nanoparticle tracking analysis, transmission electron microscopy (TEM) and Western blot. ELISA was employed to detect the expression level of exosomes
CXCL
was determined by ELISA. After
CXCL
knockdown via siRNA transfection, cells were divided into three groups: blank control, negative control and experimental groups. Cell proliferation was evaluated using the CCK-8 assay, while cell migration and invasion were assessed by Transwell assays.
Results
2
Exosomal
CXCL
expression was significantly upregulated in cervical cancer cells compared with normal c
ervical epithelial cells (
P
<
0. 01), and also markedly elevated in cervical cancer tissues compared with adjacent normal tissues. After low expression of
CXCL
knockdown significantly reduced
CXCL
expression in both cancer cells and their derived exosomes(
P
<
0. 05). Low expression markedly inhibited the proliferation, invasion and migration abilities
Conclusion
2
Silencing exosomal
CXCL
may inhibit the malignant biological behavior of cancer cells.
