The levels of IL-6 and soluble IL-33R are increased in the renal vein during surgery for clear cell renal cell carcinoma
Gudbrandsdottir, Gigja; Aarstad, Helene Hersvik; Hjelle, Karin Margrethe; Førde, Kristina; Reisæter, Lars Anders Rokne; Bostad, Leif; Aarstad, Hans Jørgen; Beisland, Christian (Journal article; Peer reviewed, 2021)Purpose The main aim was to map serum levels of IL-1/IL-6 family cytokines and relevant receptors from serum samples taken across treatment in patients with Renal Cell Carcinoma (RCC). Additionally, we explored the possible ... -
National Norwegian Practice Patterns for Surgical Treatment of Kidney Cancer Tumors ≤7 cm: Adherence to Changes in Guidelines May Improve Overall Survival
Hjelle, Karin Margrethe; Johannesen, Tom B.; Bostad, Leif; Reisæter, Lars A. R.; Beisland, Christian (Peer reviewed; Journal article, 2018-08)Background: Guidelines on surgical treatment for kidney cancer (KC) have changed over the last 10 yr. We present population-based data for patients with KC tumors ≤7 cm from 2008 to 2013 to investigate whether surgical ... -
pRb2/p130 protein expression and RBL2 mutation analysis in Burkitt lymphoma from Uganda
Kalungi, Sam; Steine, Solrun; Wabinga, Henry; Bostad, Leif; Molven, Anders (Peer reviewed; Journal article, 2009-08-19)Background: The members of the retinoblastoma protein family, pRb, p107 and pRb2 (p130), are central players in controlling the cell cycle.
