3T3 cell lines stably expressing Pax6 or Pax6(5a): a new tool used for identification of common and isoform specific target genes.
Kiselev, Yury; Eriksen, Tonje Engevik; Forsdahl, Siri; Nguyen, Lan Huong Thi; Mikkola, Ingvild (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)Pax6 and Pax6(5a) are two isoforms of the evolutionary conserved Pax6 gene often co-expressed in specific stochiometric relationship in the brain and the eye during development. The Pax6(5a) protein differs from Pax6 by having a 14 amino acid insert in the paired domain, causing the two proteins to have different DNA binding specificities. Difference in functions during development is proven by the ... -
A co-operative evaluation of different methods of detecting BCR-ABL kinase domain mutations in patients with chronic myeloid leukemia on second-line dasatinib or nilotinib therapy after failure of imatinib
Ernst, Thomas; Gruber, Franz; Mikkola, Ingvild; Pelz-Ackermann, Oliver; Maier, J; Pfirrmann, M; Muller, MC; Porkka, Kimmo; Niederwieser, D; Hochhaus, A; Lange, T (Journal article; Tidsskriftartikkel; Peer reviewed, 2009) -
Crosstalk between p38 MAPK and GR Signaling
Zeyen Øyås, Lisa; Seternes, Ole Morten; Mikkola, Ingvild (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-19)The p38 MAPK is a signaling pathway important for cells to respond to environmental and intracellular stress. Upon activation, the p38 kinase phosphorylates downstream effectors, which control the inflammatory response and coordinate fundamental cellular processes such as proliferation, apoptosis, and differentiation. Dysregulation of this signaling pathway has been linked to inflammatory diseases ... -
Generation of a PAX6 knockout glioblastoma cell line with changes in cell cycle distribution and sensitivity to oxidative stress
Hegge, Beate; Sjøttem, Eva; Mikkola, Ingvild (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-02)<i><p>Background</i>: The transcription factor PAX6 is expressed in various cancers. In anaplastic astrocytic glioma, PAX6 expression is inversely related to tumor grade, resulting in low PAX6 expression in Glioblastoma, the highest-grade astrocytic glioma. The aim of the present study was to develop a PAX6 knock out cell line as a tool for molecular studies of the roles PAX6 have in attenuating ... -
The long noncoding RNA NEAT1 and nuclear paraspeckles are up-regulated by the transcription factor HSF1 in the heat shock response
Lellahi, Seyed Mohammad; Rosenlund, Ingrid Arctander; Hedberg, Annica; Kiær, Liv Torill; Mikkola, Ingvild; Knutsen, Erik; Perander, Maria (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-10)The long noncoding RNA (lncRNA) <i>NEAT1</i> (nuclear enriched abundant transcript 1) is the architectural component of nuclear paraspeckles, and it has recently gained considerable attention as it is abnormally expressed in pathological conditions such as cancer and neurodegenerative diseases. <i>NEAT1</i> and paraspeckle formation are increased in cells upon exposure to a variety of environmental ... -
MicroRNA-193b-3p represses neuroblastoma cell growth via downregulation of Cyclin D1, MCL-1 and MYCN
Roth, Sarah Andrea; Hald, Øyvind Holsbø; Fuchs, Steffen; Løkke, Cecilie; Mikkola, Ingvild; Flægstad, Trond; Schulte, Johannes; Einvik, Christer (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-06)Neuroblastoma is the most common diagnosed tumor in infants and the second most common extracranial tumor of childhood. The survival rate of patients with high-risk neuroblastoma is still very low despite intensive multimodal treatments. Therefore, new treatment strategies are needed. In recent years, miRNA-based anticancer therapy has received growing attention. Advances in this novel treatment ... -
Pax6 regulates the expression of Dkk3 in murine and human cell lines, and altered responses to Wnt signaling are shown in Flpln-3T3 cells stably expressing either the Pax6 or the Pax6(5a) Isoform

Phosphorylation of steroid receptor coactivator-3 (SRC-3) at serine 857 is regulated by the p38 MAPK-MK2 axis and affects NF-κB-mediated transcription
Shrestha, Anup; Bruckmüller, Henrike; Kildalsen, Hanne; Kaur, Gurjit; Gaestel, Matthias; Ljones Wetting, Hilde; Mikkola, Ingvild; Seternes, Ole Morten (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-09)Steroid receptor coactivator-3 (SRC-3) regulates the activity of both nuclear hormone receptors and a number of key transcription factors. It is implicated in the regulation of cell proliferation, inflammation and in the progression of several common cancers including breast, colorectal and lung tumors. Phosphorylation is an important regulatory event controlling the activities of SRC-3. Serine 857 ... -
The third helix of the homeodomain of paired class homeodomain proteins acts as a recognition helix both for DNA and protein interactions
Bruun, Jack-Ansgar; Thomassen, Ernst I.s.; Kristiansen, Kurt; Tylden, Garth Daryl; Holm, Turid; Mikkola, Ingvild; Bjørkøy, Geir; Johansen, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2005)The transcription factor Pax6 is essential for the development of the eyes and the central nervous system of vertebrates and invertebrates. Pax6 contains two DNA-binding domains; an N-terminal paired domain and a centrally located homeodomain. We have previously shown that the vertebrate paired-less isoform of Pax6 (Pax6ΔPD), and several other homeodomain proteins, interact with the full-length ...
