Collectively, these findings suggest that Twist1-mediated modulation of MDR1/P-gp expression plays an important role in sensitization of cervical cancer cells to cisplatin, and also indicate a novel therapeutic strategy to overcome drug resistance through inactivation of Twist1 expression in cervical cancer.
The mRNA expression levels of MDR1, LRP and GSTP1 in CC were 0.57±0.32, 0.58±0.29 and 0.44±0.24, respectively, whereas those in healthy cervical tissues were 0.19±0.10, 0.17±0.14 and 0.18±0.10, respectively.
We found that miR-506 was significantly downregulated in human CC cell lines (HeLa and C33A) and clinical CC specimens as compared with matched cell lines and adjacent normal tissues, while the expression level of ABCC4 was higher in tumor tissues than it in adjacent normal tissues.
Both NOS1 and ABCG2 are important proliferation-promoting oncogenes in cervical cancer, which are expected to provide a certain theoretical basis for the treatment of cervical cancer.
This study was aimed to evaluate the short-term (72-h treatment) effects of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) on the expression and function of ABCG2 in cervix carcinoma and gastric cancer cells.
Here we report that the Polo-like kinase PLK1, an essential mitotic kinase regulator, is an important downstream effector of c-ABL in regulating the growth of cervical cancer. c-ABL interacted with and phosphorylated PLK1.
Aqueous cinnamon extract (ACE-c) from the bark of Cinnamomum cassia causes apoptosis in human cervical cancer cell line (SiHa) through loss of mitochondrial membrane potential.
In this study we evaluated the expression and function of CXCR3 and CXCR7 receptors in cervical carcinoma, rhabdomyosarcoma and glioblastoma cell lines.
It was further found that the level of knowledge on cervical cancer and PAP smear test was higher in the case group, which was more sensitive with regard to being informed about cervical cancer as compared to general society.
Considering the relationship between the purinergic signaling and cancer, we studied the E-NTPDases, ecto-5'-nucleotidase, and E-NPPs in human cervical cancer cell lines and keratinocytes.
A decrease in mtROS was found to induce formation of β-cytoplasmic actin stress fibers and circumferential rings in cervical cancer SiHa and Ca-Ski cells.
GSEA analysis of cervical cancer specimens also showed that HPV16 E6 rather than HPV18 E6, was significantly associated with actin cytoskeleton assembly.
These findings demonstrate that NHERF1 inhibits Wnt signaling-mediated proliferation of cervical cancer via suppression of ACTN4, and NHERF1 downregulation may contribute to the progression of cervical cancer.
