    • Expression and function of the miR-143/145 cluster in vitro and in vivo in human breast cancer 

      Johannessen, Charles; Moi, Line; Kiselev, Yury; Pedersen, Mona Irene; Dalen, Stig Manfred; Braaten, Tonje; Busund, Lill-Tove (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-26)
      MicroRNAs (miRNAs) are small non-coding RNAs that function as post-transcriptional regulators of gene expression and are dysregulated in cancer. Studies of miRNAs to explore their potential as diagnostic and prognostic markers are of great scientific interest. Here, we investigate the functional properties and expression of the miR-143/145 cluster in breast cancer (BC) in vitro and in vivo. The ER ...

    • A gender specific improved survival related to stromal miR-143 and miR-145 expression in non-small cell lung cancer 

      Skjefstad, Kaja Konstanse; Johannessen, Charles; Grindstad, Thea K.W.; Kilvær, Thomas Karsten; Paulsen, Erna Elise; Pedersen, Mona Irene; Dønnem, Tom; Andersen, Sigve; Bremnes, Roy M.; Richardsen, Elin; Al-Saad, Samer; Busund, Lill-Tove (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-04)
      Micro RNAs (miRNA) are small non-coding RNAs that post-transcriptionally regulate gene expression. Dysregulation of miRNA cluster 143/145 has been reported in several malignancies, but their role in non-small cell lung cancer (NSCLC) remains elusive. This study investigates the prognostic impact of miR-143 and miR-145 in primary tumors and metastatic lymph nodes in NSCLC tissue. Tissue from 553 ...

    • Molecular targets and biological effects of PAX6 in lung cancer 

      Johannessen, Charles (Master thesis; Mastergradsoppgave, 2013-05-15)
      Lung cancer is by far the leading cause of cancer-related mortality worldwide regardless of sex, and has a dismal overall 5-year survival rate of approximately 15%. More than 85% of all lung cancers are non-small cell lung cancer (NSCLC), and about 50% of these are adenocarcinomas. Targeted treatment has shown promising results in treating certain types of NSCLC, but the overall survival is still ...

    • Prognostic impact of CXCL16 and CXCR6 in non-small cell lung cancer: Combined high CXCL16 expression in tumor stroma and cancer cells yields improved survival 

      Hald, Sigurd; Kiselev, Yury; Al-Saad, Samer; Richardsen, Elin; Johannessen, Charles; Eilertsen, Marte; Kilvær, Thomas Karsten; Al-Shibli, Khalid; Andersen, Sigve; Busund, Lill-Tove; Bremnes, Roy M.; Dønnem, Tom (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-05-29)
      Background: The chemokine CXCL16 and its receptor CXCR6 are expressed by a variety of immune cells and have been shown to influence angiogenesis. The expression of CXCR6 and CXCL16 has been examined in numerous human cancers; however no studies have yet investigated their influence on prognosis in non-small cell lung cancer (NSCLC). We aimed to explore their prognostic significance in NSCLC, in ...

    • Transcription factor PAX6 as a novel prognostic factor and putative tumour suppressor in non-small cell lung cancer 

      Kiselev, Yury; Andersen, Sigve; Johannessen, Charles; Fjukstad, Bjørn; Olsen, Karina Standahl; Stenvold, Helge; Al-Saad, Samer; Dønnem, Tom; Richardsen, Elin; Bremnes, Roy M.; Busund, Lill-Tove (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-22)
      Lung cancer is the leading cause of cancer deaths. Novel predictive biomarkers are needed to improve treatment selection and more accurate prognostication. PAX6 is a transcription factor with a proposed tumour suppressor function. Immunohistochemical staining was performed on tissue microarrays from 335 non-small cell lung cancer (NSCLC) patients for PAX6. Multivariate analyses of clinico-pathological ...
