Methotrexate induced cell death mechanisms in MCF-7 adenocarcinoma breast cancer cells: Enhanced cytotoxicity following dff45-siRNA pre-treatment
Publication date: Available online 30 August 2018Source: SynergyAuthor(s): Fatemeh Kiani, Negin Rasouli, Tahereh Kashkoolinejad, Shahrokh Safarian, Seyed Jalal Zargar, Nader SheibaniAbstractThere are many efforts to diminish risks associated with the use of cancer chemotherapeutic agents through design and utilization of new strategies including gene therapy. We previously showed knockdown of dff45 or overexpression of dff40, the important apoptosis regulators, resulted in enhanced sensitization of cancer cells to chemotherapeutic agents. Here we show that pre-treatment with dff45-siRNA additively increased the overall cyt...

A Light-Driven Therapy of Pancreatic Adenocarcinoma Using Gold Nanorods-Based Nanocarriers for Co-Delivery of Doxorubicin and siRNA
In this work, we report the engineering of polyelectrolyte polymers coated Gold nanorods (AuNRs)-based nanocarriers that are capable of co-delivering small interfering RNA (siRNA) and an anticancer drug doxorubicin (DOX) to Panc-1 cancer cells for combination of both chemo- and siRNA-mediated mutant K-Ras gene silencing therapy. Superior anticancer efficacy was observed through synergistic combination of promoted siRNA and DOX release upon irradiating the nanoplex formulation with 665 nm light. Our antitumor study shows that the synergistic effect of AuNRs nanoplex formulation with 665 nm light treatment is able to inhibit...

Chemotherapy priming of the Pancreatic Tumor Microenvironment Promotes Delivery and Anti-Metastasis Efficacy of Intravenous Low-Molecular-Weight Heparin-Coated Lipid-siRNA Complex
Conclusion: These results suggested our sequential delivery of PTX-Lip and LH-Lip/siBCL-2 might provide a practical approach for PDAC or other ECM-rich tumors.

Ribosomal protein S3 selectively affects colon cancer growth by modulating the levels of p53 and lactate dehydrogenase.
In this study, we aim at determining the expression levels of RPS3 in a colon cancer cell line Caco-2 compared to a normal colon mucosa cell line NCM-460 and study the effects of targeting this protein by siRNA on cellular behavior. RPS3 was found to be expressed in both cell lines. However, siRNA treatment showed a more protruding effect on Caco-2 cells compared to NCM-460 cells. RPS3 knockdown led to a significant decrease in the proliferation, survival, migration and invasion and an increase in the apoptosis of Caco-2 cells. Western blot analysis demonstrated that these effects correlated with an increase in the level o...

Thromboxane A2 receptor‐mediated release of matrix metalloproteinase‐1 (MMP‐1) induces expression of monocyte chemoattractant protein‐1 (MCP‐1) by activation of protease‐activated receptor 2 (PAR2) in A549 human lung adenocarcinoma cells
Abstract Matrix metalloproteinases (MMPs) and monocyte chemoattractant protein‐1 (MCP‐1, CCL2) are known to be upregulated in many tumors. Their roles in tumor invasion and metastasis are being uncovered. How they are related to each other and involved in tumor progression remains to be determined. Earlier it was reported that I‐BOP‐initiated activation of thromboxane A2 receptor (TP) induced the release of MMP‐1, MMP‐3, and MMP‐9 from lung cancer A549 cells overexpressing TPα (A549‐TPα). Herein it was found that MMP‐1, but not MMP‐3 or MMP‐9, induced the expression of MCP‐1 in A549 cells. Conditi...

β‑catenin signaling pathway regulates cisplatin resistance in lung adenocarcinoma cells by upregulating Bcl‑xl.
Authors: Zhang J, Liu J, Li H, Wang J Abstract The Wnt/β‑catenin signaling pathway has been reported to regulate cisplatin resistance in several types of cancer cell. The present study aimed to investigate the role and underlying mechanism of Wnt/β‑catenin signaling in cisplatin resistance of lung adenocarcinoma cells. Wild‑type and cisplatin‑resistant A549 human lung adenocarcinoma cells (A549/WT and A549/CDDP, respectively) were cultured in vitro and exposed to different cisplatin concentrations. Cells were incubated with 10 mM lithium chloride (LiCl) to activate β‑catenin signaling. Cell prolifera...

Cognitive improvement following ischemia/reperfusion injury induced by voluntary running ‑wheel exercise is associated with LncMALAT1‑mediated apoptosis inhibition.
Cognitive improvement following ischemia/reperfusion injury induced by voluntary running‑wheel exercise is associated with LncMALAT1‑mediated apoptosis inhibition. Int J Mol Med. 2018 Feb 12;: Authors: Shang JL, Cheng Q, Duan SJ, Li L, Jia LY Abstract Previous human and animal studies demonstrated that voluntary exercise may improve cognitive function and facilitate neuronal plasticity in ischemia/reperfusion (I/R) models. However, the possible underlying mechanisms remain to be elucidated. Metastasis‑associated lung adenocarcinoma transcript 1 (MALAT1), a long noncoding RNA (lncRNA), may be as...

The prognostic value of N6-methyladenosine RBM15 regulators in lung adenocarcinoma
Cell Mol Biol (Noisy-le-grand). 2022 May 22;68(1):130-139. doi: 10.14715/cmb/2022.68.1.17.ABSTRACTN6-methyladenosine (m6A) is the most common internal modification in mammalian mRNAs while RNA-binding motif protein 15 (RBM15) is an important methyltransferase in m6A modification. Increasing evidences have shown that RBM15 has a close correlation with lung cancer. However, specific functions of RBM15 in lung adenocarcinoma (LUAD) are limited. RBM15 expression was analyzed in human LUAD tissues and matched healthy lung tissue. RBM15 was knocked down via siRNA in A549 and H1734 cells. The relationships between RBM15 with cell...

Upregulation of dual-specificity phosphatase-26 is required for transforming growth factor β1(TGFβ1)-induced Epithelial-mesenchymal transition in A549 and PANC1 cells
CONCLUSIONS: Data provided suggest that TGFβ1 modulates the expression of DUSP genes and that upregulation of DUSP26 may be required for TGFβ1-promoted EMT in A549 and PANC1 cells. Further studies should be carried out to elucidate the requirement of individual DUSPs in TGFβ1-associated EMT in tumor cells.PMID:36053282 | DOI:10.1007/s11033-022-07893-1
