Adjuvant treatment: the contribution of expression microarrays
Lønning, Per Eystein; Chrisanthar, Ranjan; Staalesen, Vidar; Knappskog, Stian; Lillehaug, Johan (Peer reviewed; Journal article, 2007-12-20) -
Alterations of the retinoblastoma gene in metastatic breast cancer
Berge, Elisabet Ognedal; Knappskog, Stian; Lillehaug, Johan; Lønning, Per Eystein (Peer reviewed; Journal article, 2011-01-21)Germline mutations affecting the retinoblastoma gene (RB1) predispose to inherited retinoblastomas but also other malignancies, including breast cancer. While somatic RB1 mutations have been detected in different malignancies, ... -
CHEK2 Mutations Affecting Kinase Activity Together With Mutations in TP53 Indicate a Functional Pathway Associated with Resistance to Epirubicin in Primary Breast Cancer
Chrisanthar, Ranjan; Knappskog, Stian; Løkkevik, Erik; Anker, Gun Birgitta; Østenstad, Bjørn; Lundgren, Steinar; Berge, Elisabet Ognedal; Risberg, Terje; Mjaaland, Ingvil; Mæhle, Lovise; Engebretsen, Lars Fredrik; Lillehaug, Johan; Lønning, Per Eystein (Peer reviewed; Journal article, 2008-08-26)Background: Chemoresistance is the main obstacle to cure in most malignant diseases. Anthracyclines are among the main drugs used for breast cancer therapy and in many other malignant conditions. Single parameter analysis ... -
Expression of biomarkers (p53, transforming growth factor alpha, epidermal growth factor receptor, c-erbB-2/neu and the proliferative cell nuclear antigen) in oropharyngeal squamous cell carcinomas
Ibrahim, Salah Osman; Lillehaug, Johan; Johannessen, Anne Christine; Liavaag, P. G.; Nilsen, Rune; Vasstrand, Endre N. (Peer reviewed; Journal article, 1999)Using immunohistochemistry, expression of p53, transforming growth factor-alpha (TGF-α), epidermal growth factor receptor (EGFR), c-erbB-2/neu and proliferating cell nuclear antigen (PCNA) was examined in 26 fresh frozen ... -
Inverse correlation between PDGFC expression and lymphocyte infiltration in human papillary thyroid carcinoma
Bruland, Ove; Fluge, Øystein; Akslen, Lars A.; Eiken, Hans Geir; Lillehaug, Johan; Varhaug, Jan Erik; Knappskog, Per (Peer reviewed; Journal article, 2009-12-08)Background: Members of the PDGF family have been suggested as potential biomarkers for papillary thyroid carcinomas (PTC). However, it is known that both expression and stimulatory effect of PDGF ligands can be affected ... -
Mutations of the p53 gene in oral squamous-cell carcinomas from sudanese dippers of nitrosamine-rich toombak and non-snuff-dippers from the Sudan and Scandinavia
Ibrahim, Salah Osman; Vasstrand, Endre N.; Johannessen, Anne Christine; Idris, Ali M.; Magnusson, Bengt; Nilsen, Rune; Lillehaug, Johan (Journal article, 1999-11-08)Using PCR-SSCP/DNA sequencing methods, we analyzed 14 oral squamous-cell carcinomas (OSCCs) and 8 pre-malignant oral lesions from different Sudanese patients for prevalence of mutations in exons 5 to 9 of the p53 gene in ... -
Predictive and Prognostic Impact of TP53 Mutations and MDM2 Promoter Genotype in Primary Breast Cancer Patients Treated with Epirubicin or Paclitaxel
Chrisanthar, Ranjan; Knappskog, Stian; Løkkevik, Erik; Anker, Gun Birgitta; Østenstad, Bjørn; Lundgren, Steinar; Risberg, Terje; Mjaaland, Ingvil; Skjønsberg, Gudbrand; Aas, Turid; Schlichting, Ellen; Fjösne, Hans E.; Nysted, Arne; Lillehaug, Johan; Lønning, Per Eystein (Peer reviewed; Journal article, 2011-04-27)Background: TP53 mutations have been associated with resistance to anthracyclines but not to taxanes in breast cancer patients. The MDM2 promoter single nucleotide polymorphism (SNP) T309G increases MDM2 activity and may ... -
The Swedish Snus and the Sudanese Toombak: are they different?
Idris, Ali M.; Ibrahim, Salah Osman; Vasstrand, Endre N.; Johannessen, Anne Christine; Lillehaug, Johan; Magnusson, Bengt; Wallström, M.; Hirsch, Jan M.; Nilsen, Rune (Journal article, 1998-11)In Sweden, snuff (locally known as snus), was introduced since the year 1637. Presently, Sweden has the highest per capita consumption and sale figures of snuff in the world, and the habit is becoming increasingly popular. ...
