Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Cyclooxygenase-2 is Involved in the Progression of Thyroid Cancer [PDF]

open access: yes, 2009
Although the inducible form of cyclooxygenase (COX), COX-2, is highly expressed in various cancers and it is also involved in cancer progression, its role in thyroid cancer is not fully understood.

Expression of cyclooxygenase-1 and 2 in chronic tonsillitis

open access: yesIndian Journal of Pathology and Microbiology, 2010
Objectives: Prostaglandins are critical mediators of inflammation and affect both humoral and cell-mediated immune responses. Recent findings show that T and B cells express COX-2 upon activation. The purpose of this study is to investigate the potential

Immunohistochemical Expression of Cyclooxygenase-2 in endometrioid carcinoma

open access: yesAdvanced Medical Journal
Background and objectives: Cyclooxygenase-2 functions as an enzyme which synthesize prostaglandins from Arachidonic acid Cyclooxygenase -2 is one of the important factors in maintaining the endometrium during menstrual cycle.

Cyclooxygenase 2 as a Marker of Early Pregnancy Loss in Cytomegalovirus Infection

open access: yesActa Biomedica Scientifica, 2020
Background. Increased expression of cyclooxygenase 2 in the placenta plays a significant role in the formation of placental disorders in the pathological course of pregnancy.

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Cyclo-Oxygenase 2 Modulates Chemoresistance in Breast Cancer Cells Involving NF-κB

open access: yesCellular Oncology, 2009
Background: Breast cancer cells can develop chemoresistance after prolonged exposure to cytotoxic drugs due to expression of the multi drug resistance (MDR) 1 gene.

Preoperative circulating tumor cells integrated with imaging analysis for prognostic evaluation in head and neck squamous cell carcinoma

open access: yesMolecular Oncology, EarlyView.
Detecting circulating tumor cells (CTCs) in blood before surgery may help predict outcomes in patients with head and neck squamous cell carcinoma (HNSCC). Here, we show when combined with tumor size and lymph node involvement from routine imaging, CTC status identifies high‐risk patients with poorer survival—offering a simple, minimally invasive tool ...

Common promoter variant in cyclooxygenase-2 represses gene expression: evidence of role in acute-phase inflammatory response [PDF]

open access: yes, 2002
Objective: Cyclooxygenase (COX)-2 is a key regulatory enzyme in the synthesis of prostanoids associated with trauma and inflammation. We investigated the COX-2 gene for functional variants that may influence susceptibility to disease.

Brain cyclooxygenase-2 mediates interleukin-1-induced cellular activation in preoptic and arcuate hypothalamus, but not sickness symptoms

open access: yesNeurobiology of Disease, 2010
Interleukin-1ß acts on the CNS to induce fever, neuroendocrine activation, and behavioral changes, but cannot passively cross the blood–brain barrier. According to a widely accepted hypothesis interleukin-1ß induces the synthesis of cyclooxygenase-2 at ...
