(2007) Expression of NF-kappaB parallels COX-2 expression in oral precancer and cancer: association with smokeless tobacco.Int.J.Cancer, 120, 2545-2556].
Cyclooxygenase-2 (COX-2) is overexpressed in various types of human malignancies including squamous cell carcinomas (SCCs) of the esophagus, but little is known about COX-2 expression in premalignant esophageal squamous dysplasia.
Cyclooxygenase-2 (COX-2) upregulation is recognized to confer advantage in progression in a wide variety of cancers, with colorectal cancer most intensively investigated.
Cyclooxygenase-2 (COX-2) is one of the rate-limiting enzymes in metabolism of arachidonic acid, and COX-2 inhibitors demonstrate preventive effects on cancer, especially on colorectal cancer.
COX-2 messenger RNA (mRNA) was detected in 3 of 4 patients with Dukes' stage A, 13 of 14 patients with Dukes' stage B, and 10 of 11 patients with Dukes' stage C or D. COX-2 mRNA was detected in 5 of 7 patients with proximal cancer and in 21 of 22 patients with distal cancer.
Cyclooxygenase-2 (COX-2) has been implicated in a variety of human malignancies and, accordingly, COX-2 selective inhibitors are being investigated as important chemopreventive and therapeutic agents.
COX-2 protein expression was found in cancer as well as the surrounding stromal cells (including infiltrating inflammatory cells and endothelial cells of tumor-associated microvessels).
Cyclooxygenase-2 (COX-2), an inducible enzyme involved in prostaglandin (including PGE(2)) biosynthesis, is overexpressed in several epithelial malignancies including breast cancer.
Cyclooxygenase-2 (COX-2) is a key enzyme that catalyzes the biosynthesis of prostaglandins from arachidonic acid and plays a critical role in some pathologies including inflammation, neurodegenerative diseases and cancer.
Cyclooxygenase-2 (Cox-2) is a key enzyme in the conversion of arachidonic acid to prostaglandins that has been shown to have a particular importance in the progression of several malignancies including nasopharyngeal carcinoma (NPC).
Cyclooxygenase-2 (COX-2), involved in the inhibition of apoptosis and, the potentiation of cell growth, is frequently overexpressed in human malignancies including osteosarcoma (OS).
Cyclooxygenase 2 (COX-2) receptors are present on neoplastic cells and are proposed to participate in initiation, transformation, progression and metastasis of cancer.
