These results indicate that ultrasound-mediated PTX-miR-34a-MBs synergistically inhibit the growth of cervical cancer via the upregulation of miR-34a and downregulation of Bcl-2 and CDK6.
As reported before, aberrant expression of proteins associated with signaling pathways, such as phosphatidylinositol 3-kinase(PI3K), EGF-R, β-catenin, and Erk and Bcl-2 was discovered in CC.
In the present study, we investigated the regulation by cisplatin on protein kinase C β (PKC β), on B-cell lymphoma 2 (Bcl-2) and on apoptosis in cervical cancer Hela cells.
The up-regulation of Bcl2 and c-Met promotes the cervical cancer's progress, and the expression of miR-34a and miR-206 significantly correlated with the progression and prognosis in cervical cancer.
The present study aimed to investigate the effect of ALA‑PDT on human cervical cancer through the regulation of microRNA‑143 (miR‑143) and the Bcl-2/Bax signaling pathway.
Therefore, our research revealed the mechanistic links between miR-744 and Bcl-2 in the pathogenesis of cervical cancer through modulation of Caspase-3, leading to the inhibition of cervical cancer cell growth.
Bcl-2 up-regulation has been implicated in the resistance to cisplatin in a variety of cancer cell lines, however its role in cervical cancer is confounding.
Mifepristone reversed the resistance of HeLa/MMC cells to MMC in vitro; the overexpression of the GCS gene and the increased expression of apoptosis-related protein Bcl-2 may play important roles in the formation of multidrug resistance in cervical cancer.
Our data demonstrated that leptin interferes with the expression of oncogenic c-myc and anti-apoptotic bcl-2, and regulates cell turnover and facilitates the progression of cervical cancer.
Direct involvement in the regulation of Bcl-2 may be one of the mechanisms through which miR-143 may play a role in the pathogenesis of cervical cancer.
Our data demonstrated that MALAT1 was involved in cervical cancer cell growth, cell cycle progression, and invasion through the regulation of gene expression, such as caspase-3, -8, Bax, Bcl-2, and BclxL, suggesting that MALAT1 could have important implications in cervical cancer biology.
ARL6IP1 was involved in cervical cancer cell growth, cell cycle progression, and invasion through regulation of gene expression, such as Caspase-3, Caspase-9, p53, TAp63, NF-κB, MAPK, Bcl-2, and Bcl-xL, suggesting that ARL6IP1 could have important implications in cervical cancer biology.
To analyze aberrant expression of the apoptotic protein p53 and the anti-apoptotic protein Bcl-2 in premalignant lesions of the uterine cervix induced by human papillomavirus (HPV) infection and its significance for early diagnosis of cervical cancer.
Features of Notch1 activation as measured by intracellular Notch1, high levels of Jagged1, Hes1 and Cdk9 were paralleled by nuclear translocation of both NF-kappaB p50 and p65 with target gene expression (IkappaB-alpha, Bcl-2, and CyclinD1) in human cervical cancer sections.
Deregulation of the apoptotic machinery plays a major role in cell death, cellular transformation and cancer. p53, Bcl-2, Bcl-XL, Bax and Mdm2 mRNA expression patterns were evaluated in tissue samples with cervical intraepithelial neoplasia (CIN) and cervical cancer compared to those of normal cervical tissues, and correlated with the underlying cervical lesions.
Our study suggests that coexpression of ER, PR, and bcl-2 may be a useful tool in identifying the CIN III lesions with low risk of progression to cervical cancer.
