All results demonstrated that HPPDC nanoparticles can efficiently overcome drug resistance in breast cancer both in vitro and in vivo by combining chemotherapy and COX-2 inhibitor.
The incidence of new-onset breast cancer in NSAID users was significantly decreased in users taking selective cyclooxygenase 2 inhibitors, diclofenac, ibuprofen and piroxicam.
ELISA was conducted to check the concentrations of proteins involved in multiple intracellular signaling pathways, responsible for the promotion of tumor growth and breast cancer progression, namely matrix metalloproteinase (MMP)‑2, matrix MMP‑9, tumor necrosis factor‑α (TNF‑α), cyclooxygenase‑2 (COX‑2), soluble intercellular adhesion molecule 1 (sICAM1) and mTOR.
Kaplan‑Meier survival analysis revealed that six DElncRNAs (INC AC112721.1, LINC00536, MIR7‑3HG, ADAMTS9‑AS1, AL356479.1 and LINC00466), nine DEmRNAs (KPNA2, RACGAP1, SHCBP1, ZNF367, NTRK2, ORS1, PTGS2, RASGRP1 and SFRP1) and two DEmiRNAs (hsa‑miR‑301b and hsa‑miR‑204) had significant effects on overall survival in BC.
We found a statistically significant concordant correlation between extensive HCMV-IE and COX-2 (P < 0.0001) as well as with HCMV-IE and 5-LO (P = 0.0003) in infiltrating BC.
Solid lipid nanoparticles (CLX-SLN), nanostructured lipid carriers (CLX-NLC) and a nanoemulsion (CLX-NE) of celecoxib (CLX), a selective cyclooxygenase-2 inhibitor, were formulated for use in remedy of breast cancer and acute promyelocytic leukemia.
Celecoxib (CXB), a selective cyclooxygenase-2 (COX-2) inhibitor, has antiangiogenetic activity and inhibitory effect on tumor metastasis, and can also enhance the sensitivity of chemotherapeutic drug doxorubicin (DOX) in breast cancer.
Here, we aim to investigate the effect of two novel compounds A and B possessing triaryl structures, which interact with both COX-2 and TGF-β active sites and suppress NF-κB activation, on EMT in a co-culture system with breast cancer and stromal cells.
Activation of HIF-1<i>α</i> by <i>δ</i>-Opioid Receptors Induces COX-2 Expression in Breast Cancer Cells and Leads to Paracrine Activation of Vascular Endothelial Cells.
The enzymes Cyclooxygenase-2 and Phosphoinositide-3-Kinase are most responsible for the corresponding diseases such as inflammation and breast cancer respectively.
HuR and COX-2 protein expression was assessed immunohistochemically on paraffin-embedded breast cancer tissue sections obtained from 121 patients and was statistically analyzed with clinicopathological parameters, estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2), as well as with tumor cells' proliferative capacity and overall and disease-free patients' survival.
Knockdown delta-5-desaturase in breast cancer cells that overexpress COX-2 results in inhibition of growth, migration and invasion via a dihomo-γ-linolenic acid peroxidation dependent mechanism.
1.There are numerous investigations demonstrating that the cyclooxygenase-2 (COX-2) inhibitors might enhance the efficiency of anastrozole in breast cancer.
15-Deoxy-Δ<sup>12,14</sup>-prostaglandin J<sub>2</sub> (15d-PGJ<sub>2</sub>), one of the terminal products of cyclooxygenase-2-catalized arachidonic acid metabolism, has been shown to stimulate breast cancer cell proliferation and migration through Akt activation, but the underlying mechanisms remain poorly understood.
