Additionally, TRIM32 overexpression promoted lung cancer cell proliferation and motility and mediated the expression of Bax, Bcl-2, cleaved caspase-3, matrix metalloproteinase-2 (MMP-2) and MMP-9 were inhibited by JAK2/STAT3 signaling inhibitor (AG490).
Moreover, we found that the simultaneous administration of fucoidan and cisplatin synergistically inhibited lung cancer cell viability via inducing apoptotic responses, including upregulating cleaved caspase-3 and poly (ADP ribose) polymerase (PARP) expression.
The results indicated that the growth of lung cancer cells A549 might be inhibited with Spica prunellae through activating the proapoptotic protein caspase-3 and inducing cellular apoptotic pathway.
We report the translation of [<sup>18</sup>F]ICMT-11 PET to measure chemotherapy-induced caspase-3/7 activation in breast and lung cancer patients receiving first-line therapy.
In conclusion, this study suggests that Biochanin A inhibits the proliferation of lung cancer cells and induces cell cycle arrest and apoptosis mainly by regulating cell cycle-related protein expression and activating the Bcl-2 and Caspase-3 pathways, thus suggesting that Biochanin A may be a promising drug to treat lung cancer.
TUNEL assay, AV-PI staining and Caspase-3 activity assay measured the effect of the decrease of miR-328 on lung cancer cell apoptosis at both in vivo and in vitro level.
The present study concluded that baicalein combined with cisplatin induced cytotoxicity and apoptosis of A549 cells, and such activity may be associated with the regulation of Bcl-2, Bax and caspase-3, indicating a promising alternative method for lung cancer.
In conclusion, these results indicate that the effects of GluA2 in lung cancer are mediated by the caspase-3 and p53/p21<sup>Cip1/Waf1</sup>/p16<sup>INK4a</sup> signaling pathways.
Our results demonstrated that PA showed significant anti-tumor activity on lung cancer in vitro; the mechanisms were involved in inducing mitochondria-mediated apoptosis via up-regulation of caspase-3, caspase-8, caspase-9, Bid, Bax, down-regulation of Bcl-2 and stimulating the release of Cyto-C from mitochondria.
To further explore the possible impact of 829 A>C SNP on CASP3 transcriptional activity, we detected the dual luciferase activity of PGL3-promoter vectors containing 829A or 829C alleles in lung cancer cell lines and found that report gene expressions driven by 829A containing CASP3 promoter were 1.64-fold, 1.94-fold greater than those driven by CASP3 829C containing counterparts in A549 and NCI-H1975 cells (P<0.001).
Our study provides new insight in understanding of oncogenic role of miR-224 in the lung cancer pathogenesis and suggests that NF-κB/miR-224/CASP3, 7 pathway could be a putative therapeutic target in lung cancer.
Following modification with apoptin, MSCs retained their differentiation capacity, and successfully synthesized and secreted apoptin, which entered target cells and selectively induced lung cancer cell apoptosis through activating caspase-3.
IC50 values measured by sulforhodamine B (SRB) assay at 72 h and apoptosis assays (annexin V staining, cleavage of PARP and caspase-3) suggest that FLLL12 is 5-10-fold more potent than curcumin against a panel of premalignant and malignant lung cancer cell lines, depending on the cell line.
These results demonstrate that gemcitabine: (i) induces up-regulation of FasL in lung cancer cells triggering cell apoptosis via an autocrine/paracrine loop; (ii) induces a Fas-dependent apoptosis mediated by caspase-8 and caspase-3 activation; (iii) enhances the sensitivity of lung cancer cells to cytotoxic activity of LAK cells and malignant pleural fluid lymphocytes, partially via Fas/FasL pathway.
Condurango glycoside-rich components stimulate DNA damage-induced cell cycle arrest and ROS-mediated caspase-3 dependent apoptosis through inhibition of cell-proliferation in lung cancer, in vitro and in vivo.
The impact of miRNA-21 on the expression of cyclin D1, caspase-3, and matrix metalloprotease-9 (MMP9) was also studied. miRNA-21 expression was significantly higher in lung cancer cell lines (A549, HCC827, NCI-H282, and 95-D) than that in normal human bronchial epithelial cells (HBE; p < 0.05).
In the case of the CASP3 77G>A, subjects with the GG genotype were at a 1.19-fold increased risk of lung cancer compared with those with at least one variant allele.
To explore the possibility that the genetic alterations of CASP3, which encodes caspase-3, might be involved in the development of human tumors, we analyzed the entire coding region and all splice sites of human CASP3 gene for the detection of somatic mutations in a series of 944 human tumors, including 165 stomach carcinomas, 95 colon carcinomas, 76 breast carcinomas, 80 hepatocellular carcinomas, 181 non-small cell lung cancers, 45 acute leukemias, 28 multiple myelomas, 12 medulloblastomas, 15 Wilms' tumors, 12 renal cell carcinomas, 40 esophagus carcinomas, 33 urinary bladder carcinomas, 33 laryngeal carcinomas, and 129 non-Hodgkin lymphomas.
Adenovirus mediated IkappaBalpha gene transfer improve the anti-cancer effect of paclitaxel to lung cancer cells through the regulation of caspase 3 activation.
