Tumour promoting and suppressing roles of the atypical MAP kinase signalling pathway ERK3/4-MK5.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)Perturbed action of signal transduction pathways, including the mitogen-activated protein (MAP) kinase pathways, is one of the hallmarks of many cancers. While the implication of the typical MAP kinase pathways ERK1/2-MEK1/2, p38MAPK and JNK is well established, recent findings illustrate that the atypical MAP kinase ERK3/4-MK5 may also be involved in tumorigenic processes. Remarkably, the ERK3/4-MK5 ... -

Autocrine Prostaglandin E-2 Signaling Promotes Tumor Cell Survival and Proliferation in Childhood Neuroblastoma
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)Prostaglandin E2 (PGE2) is an important mediator in tumor-promoting inflammation. High expression of cyclooxygenase-2 (COX-2) has been detected in the embryonic childhood tumor neuroblastoma, and treatment with COX inhibitors significantly reduces tumor growth. Here, we have investigated the significance of a high COX-2 expression in neuroblastoma by analysis of PGE2 production, the expression pattern ... -
Any difference? : use of a CAM provider among cancer patients, coronary heart disease (CHD) patients and individuals with no cancer/CHD
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)Background: Although use of complementary and alternative medicine (CAM) among cancer patients has been described previously, prevalence of use has not commonly been compared to other disease groups in a true population sample where CAM use or cancer is not the main focus.
